Compared with ordinary level, laser leveling instrument has the following five advantages: (1) The measuring range is longer than the general level and safe to use (for specific instruments, please refer to the instrument manual). In general, when the naked eye stares at the ray for more than 15min, the laser ray emitted by the instrument will not cause harm to the human body), and it can also be observed day and night to establish a constant visual plane reference. (2) The instrument has the advantages of convenient carrying, light weight and low power consumption, and can work normally in complex terrain and harsh environment. The calibration of the instrument is simple and easy, and can be carried out on site. (3) It can eliminate the delay and increase the cost of retest caused by information communication failure, misunderstanding of contact signal, ruler reading error and operation error in conventional leveling. (4) The whole process dynamic monitoring can be carried out, so as to reduce the material and cost loss caused by ultra deep excavation foundation or ultra thick pouring concrete. (5) It can be operated by one person, fast and accurate, saving manpower, reducing cost, simple operation, easy to learn and learn; It can also save 1 / 2-2 / 3 of time. Automatic laser sweeper is one of the crystallization of the close combination of microelectronics technology, laser technology, precision machinery manufacturing technology and surveying and mapping science. It is mainly used for horizontal and vertical control in large-scale water conservancy construction, high-rise building and civil engineering construction. Such as precise leveling survey of concrete ground, large equipment foundation and other surface layers, large-area high-precision land leveling, railway track laying survey, tunnel subgrade track laying survey, etc. Automatic laser leveling instrument has incomparable advantages over level instrument, and can do many jobs that level instrument is not competent for.

When the laser leveler is placed horizontally, a plumb plane and a horizontal line can be generated. Then the remote control can be used for remote operation. The laser is compensated to the horizontal through the automatic compensation mechanism in the machine, and the laser is emitted. When the compensation range is exceeded, stop rotating and emitting laser, and the alarm light will be on. Hang the inner cylinder seat with hanging wire, install the laser diode in the center, and generally emit laser in a vertical direction. The laser emitted in the vertical direction is rotated and emitted in the horizontal direction through the objective lens and the pentagonal prism installed on the motor. Observe the alarm lamp to know whether it is within the automatic leveling compensation range and whether the host is inclined. This can be determined by controlling the gap between the inner cylinder seat and the outer cylinder seat through electronic methods.

The use method of laser vertical collimator 1. The setting of ± 0.00 floor control point is very important. Firstly, the best control line should be determined according to the shape and structure of the project. Secondly, choose the most reasonable control point position on the control line. The control points must avoid reinforced concrete components and other unfavorable factors that affect intervisibility. Ensure good intervisibility between points. 2. After the initial determination of the point location, pay attention to see the structural drawing of the upper part of the point location clearly to ensure that the vertical projection of the point location is on the concrete slab surface. Due to the fact that the structure is staggered, it is necessary to ensure that each floor can be projected onto the floor. 3. Accurately match and verify the determined points. The accuracy of ± 0.00 floor points directly determines the axis projection accuracy of the main structure. 4. After the upper formwork is supported, the control points shall be accurately hoisted on the formwork before the reinforcement, and 150 * 150 holes shall be reserved. Make sure you dig in the air. 5. After concrete pouring, when the upper axis is measured. A plumb meter is set up at the control point, and the laser beam is projected upward at the control point, and the upper layer is received by the laser receiving target. And rotate the plumber 360 ° to see its eccentricity, and take the center to measure the floor. 6. Do a good job in the protection of ± 0.00 layer control points to ensure that they are not damaged. Plumb meter is suitable for high-rise buildings, and the precision of internal control is higher; It is less affected by the weather; The disadvantages are: 1. 2. The reserved hole of concrete slab surface is not easy to repair, which affects the integrity of slab surface. 3. The hidden danger of safety is big, so special attention should be paid to the protection. When measuring, every hole should be opened. If there are falling objects in the hole, it is easy to damage the plumb meter. Although the accuracy of plumb meter is very high, it is easy to set up primary control network in 10 layers.

Tower ruler is a kind of level ruler. Most of the early level rulers were made of wood, which was heavy and limited in length (generally 2m), so it was not convenient to carry when measuring. Later, it was gradually made of aluminum alloy and other light and high-strength materials, and adopted tower shrinkage form. It was easy to draw out when in use, and the range of single elevation measurement was greatly improved. The length was generally 5m, and it could be contracted when carrying. Because its shape was similar to tower shape, it was often called tower ruler. As the tower ruler is made of metal, the height of all the tower rulers can reach 5m, and most of the tower rulers are used outdoors. Therefore, it is necessary to keep away from the wires to prevent electric shock accidents. When measuring river water level with tower ruler, attention should also be paid to prevent drowning. Use of folding tower ruler The tower ruler is mostly of rectangular drawing structure, and the snap spring pops up at each drawing section. When using, it is necessary to pay attention to whether the snap spring is in place, otherwise the measurement error will be caused. In order to facilitate observation and debate, the distance is marked with a red point above or below the number on the tower ruler. If there is a red point on the number, it means the range of 1m section, and two red points mean the range of 2m section... And so on. If the number on the tower ruler is "4", it means 4m. Maintenance of folding tower ruler The surface of the ruler should be kept clean to prevent damage. The bottom plate of the ruler is easy to be damaged by moisture due to water or wet mud. It should be kept dry and fixed with screws. When using the tower ruler, pay attention to the looseness of the interface and spring plate, and when pulling out the upper section of the tower ruler. Pay attention to whether the interface is secure. If it falls off and is not found, the reading will be wrong. requirement The leveling staff is the length standard for measuring the height difference. If there is any error in the length of the leveling staff, it will bring systematic error influence on the observation results of precision leveling. Therefore, the following requirements are put forward for the precision leveling staff: (1) When the temperature and humidity of the air change, the length of the dividing line of the leveling rod must be kept stable or only slightly changed. In general, the dividing of precision level is painted on invar alloy belt, and invar alloy belt is stretched in the groove of wooden ruler body with a certain tensile force, so that the length of invar alloy belt will not be affected by the expansion and deformation of wooden ruler body. The number of leveling rod division is marked on the wooden ruler on both sides of invar alloy belt, as shown in Fig. 5-7 (a) and (b). (2) The division of the leveling rod must be very correct and precise, and the accidental error and systematic error of the division should be very small. The magnitude of accidental error and systematic error of leveling rod division mainly depends on the level of division and calibration technology. At present, the accidental mean square error of precise leveling rod division is generally in the range of 8 ~ 11 M. Because the systematic error of precise leveling rod division can be corrected by the average true length per meter of leveling rod, the accidental error of division represents the comprehensive accuracy of leveling rod division. (3) The structure of the leveling rod should be straight, and the length, bending and torsion of the ruler body are not easy to occur. Generally, the wooden body of precise leveling rod should be made of high-quality wood with special treatment. In order to avoid changing the length of the leveling rod due to the wear of the bottom of the leveling rod in use, a solid and wear-resistant metal base plate must be nailed on the bottom of the leveling rod. In the precise leveling operation, the leveling rod shall be erected on the special ruler pad or ruler pile with certain weight. The shape of ruler pad and ruler pile is shown in Figure 5-8. (4) A round level device shall be attached to the body of the precise level staff, so as to keep the level staff in a vertical position during operation. Generally, the ruler supporting ring should be installed on the ruler body, so that the ruler supporting person can make the leveling rod stable in the vertical position. (5) In order to improve the alignment accuracy of leveling rod division, the form and color of leveling rod division are coordinated with the color of leveling rod. Generally, the precise leveling rod is divided by black lines, as shown in Figure 5-7. It is helpful for the accurate alignment of leveling rod division during observation by combining with the light yellow ruler. There are two kinds of dividing values of line dividing precision leveling staff: l0 mm and 5mm. As shown in Fig. 5-7 (a), the precise leveling staff with division value of lomm has two rows of divisions. The row of division notes on the right side of the ruler from 0 to 300cm is called the basic division, the row of division notes on the left side from 300 to 600cm is called the auxiliary Division, and the reading difference between the basic division and the auxiliary division at the same height is a constant, which is called the basic auxiliary difference, usually called the ruler constant, Leveling operation can be used to check the accuracy of readings. As shown in Figure 5-7 (b), the precision level with a grid value of 5mm also has two rows of dividers, but the two rows of dividers are staggered by 5mm, so in fact, the left side is odd dividers, and the right side is even dividers, that is, the odd dividers and even dividers occupy one row respectively, without auxiliary dividers. The right side of the wooden ruler is marked with the meter number, and the left side is marked with the decimeter number. The whole mark is from 0.1 to 5.9 M. the actual division value is 5 mm, and the division mark is twice larger than the actual value. Therefore, the actual elevation difference value measured by this kind of leveling rod must be divided by 2. The precise leveling staff with a grid value of 5mm also has an auxiliary dividing line. The bar code level used with the digital code level is shown in Figure 5-9. Through the detector of digital code level to identify the bar code on the level, and then through digital image processing, give the reading on the level, instead of the visual reading on the level.

A horizontal plane and a plumb line can be produced when the laser sweeper is placed vertically, and a plumb plane and a plumb line can be produced when the laser sweeper is placed horizontally. Then remote control can be used for remote operation. The laser is compensated to the level by the automatic compensation mechanism in the machine, and the laser is emitted. When it exceeds the compensation range, stop rotating and emitting laser, and the alarm light will be on. The inner cylinder seat is suspended by hanging wire, and the laser diode is installed in the center position. Generally, the laser is emitted in the vertical direction. The laser emitted in the vertical direction rotates horizontally through the objective lens and the pentagonal prism mounted on the motor. Observe the alarm light to see whether it is within the range of automatic leveling compensation and whether the main engine is inclined. This can be determined by controlling the gap between the inner cylinder seat and the outer cylinder seat through electronic methods. Extended information: The receiver of laser scanner is composed of two receiving diodes and a display. The former receives the laser and the latter displays the spot position. At the same time, the position of the light spot is adjusted by the buzzer with different timbre. The receiver is the upper and lower photodiodes, which indicate the position according to the light difference between the two photodiodes. The laser is not illuminated by photodiode 2 in a, which is indicated by the downward arrow. B photodiodes 1 and 2 are exposed to the same amount of light, indicated by the center mark. An instrument that projects a visible laser beam, according to which the height can be leveled. Another concept is to make the visible laser point (generally red light and green light) sweep the light of the same Leveling Height under the drive of the fast rotating axis, which is a kind of instrument for engineers to locate the leveling height.

The laser vertical collimator is an optical instrument which gives the vertical line of lead based on the gravity line. It can be used to measure the small horizontal deviation relative to the plumb line, to transmit the point position of the plumb line, to measure the vertical contour of the object and to transmit the vertical orientation. It is mainly used in the construction of high-rise buildings, high towers, chimneys, high towers, launching wells, frames, installation of large cylindrical mechanical equipment, horizontal displacement measurement of dams, engineering supervision and deformation observation, etc. Main technical parameters:

Laser sweeper General concept An instrument that projects a visible laser beam according to which the height can be leveled. Another concept is to make the visible laser point (generally red light and green light) sweep the light of the same Leveling Height under the drive of the fast rotating axis, which is a kind of instrument for engineers to locate the leveling height. How folding works For the planimeter which projects the visible beam, it is to use the visible beam to fix the height (the light propagates in a straight line). For the instrument of light spot scanning line, it uses the principle that when the visible laser spot is moving rapidly, because the human vision is temporary, people see that the movement of light spot is a line. When the instrument is leveled, the photoelectrically swept lines are at the same height. Folding type At present, according to the working principle and whether to add a compensation mechanism or not, the laser scanners commonly used in China can be roughly divided into three categories: bubble laser scanners, automatic leveling laser scanners and electronic automatic leveling laser scanners. Folding auto leveling laser scanner The sjz1 automatic leveling instrument developed by Beijing optical instrument factory uses the hanging wire optomechanical compensator to achieve the purpose of automatic leveling within the scope. No matter how the instrument tilts, the laser plane scanned will always be kept in the horizontal plane within the compensation scope. This instrument is suitable for the construction site with large vibration. Folding electronic automatic laser leveling instrument The opto mechanical compensator has the advantages of simple structure, low cost and anti vibration. However, its compensation accuracy decreases with the increase of compensation range, and the general compensation range is limited to more than ten minutes. The modern development of electronic automatic leveling principle can expand the range to about, and has high stability and compensation accuracy. Electronic automatic leveling system is generally composed of sensors, electronic circuits and actuators. The bubble sensor is made up of glass bubble filled with conductive liquid, which is similar to ordinary bubble level. The glass tube is coated with metal cover, and two symmetrical electrodes are formed. There are two resistances between the two electrodes. When the bubble is in the middle, the resistance is equal. When the bubble is inclined, the bubble moves, which destroys the balance state of the two resistances. As a result, the bridge composed of the sensor circuit loses balance and generates the corresponding voltage output. The output signal is electronically processed and amplified to drive the actuator, which makes the servo motor produce the corresponding forward or reverse rotation In addition to resistance, the sensor also uses capacitive or inductive sensing elements.

At present, according to the working principle and whether to add a compensation mechanism or not, the laser scanners commonly used in China can be roughly divided into three categories: bubble laser scanners, automatic leveling laser scanners and electronic automatic leveling laser scanners. Folding bubble laser sweeper The sj2 and SJ3 laser scanners developed by Beijing optical instrument factory in 1996 are simple in structure and low in cost The low cost bubble laser sweeper is suitable for construction, interior decoration and other construction work. After passing through the pentagonal prism, the laser beam is divided into two beams. One beam directly passes through the pentagonal prism, and the other beam changes the direction of 90 degrees. The rotating head of the instrument is driven by the motor through the belt to form a scanning laser plane. The instrument is equipped with a long leveling instrument for Anping instrument. (like the bubble level, the leveling instrument is based on the level, that is to say, the horizontal error of the laser plane depends on the accuracy of the level. If the instrument is placed horizontally, the vertical plane scanned by the laser can be obtained according to the vertical level.) The accuracy of this instrument is largely affected by human factors. Due to the requirements of fast and convenient operation in engineering construction and high precision in some special occasions, bubble leveling is difficult to meet the requirements. Therefore, various automatic laser instruments emerge as the times require, and some unique leveling methods are produced
