Description

Technical Field

[0001] The present invention relates to the technical field of bridge compactness monitoring, and particularly to a method for monitoring the concrete compactness of a water-drop curve-shaped pylon. Background Art

[0002] A cable-stayed bridge is a bridge structure system mainly composed of cable stays, and is composed of a compression tower, a tensioned cable and a bending beam. With the progress of technology, the cable-stayed bridge technology is also constantly innovating. The cable-stayed bridge with a water-drop curve-shaped main tower is favored for its simple appearance, dynamic and gentle beauty.

[0003] During the construction process of a cable-stayed bridge with a water-drop curve-shaped main tower, it is necessary to carry out maintenance operations after the concrete pouring of the main tower column. After maintenance, it is necessary to monitor the concrete compactness, mainly for the guarantee of structural safety and bearing capacity. In the monitoring of concrete compactness in cable-stayed bridges, ultrasonic monitoring instruments are mainly used, and flexible probes are used as supporting equipment. The places in the tower column that require concrete compactness monitoring are mainly divided into four parts: the connection section from the top of the tower to the tower body, the curvature change section in the middle of the tower body, the transition area between the enlarged section at the bottom of the tower and the tower body, and the connection node between the pylon and the cross beam. Among them, the first connection section from the top of the tower to the tower body requires high-altitude operations.

[0004] However, in the actual monitoring of concrete compactness, the staff carry ultrasonic monitoring equipment to the designated position at the top of the cable-stayed bridge, use three-dimensional laser scanning to model, dynamically adjust the measuring point spacing along the curved surface, then apply the coupling agent to the measuring point grid position, attach the flexible probe to the coupling agent and slide it along the trajectory. Since the staff's high-altitude operations are interfered by wind, the coupling agent will be blown into an irregular shape, and since the top of the tower column is a curved surface, the coupling agent will flow away too quickly under the action of gravity after being poured on the measuring point grid, making it easy for the staff to have poor signal when using the flexible probe, resulting in a long monitoring operation time and low efficiency. Therefore, the present application provides a method for monitoring the concrete compactness of a water-drop curve-shaped pylon to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a method for monitoring the concrete compactness of a water-drop curve-shaped pylon to solve the problems in the existing situation, that is, due to the interference of wind during the staff's high-altitude operations, the coupling agent is blown into an irregular shape, and since the top of the tower column is a curved surface, the coupling agent will flow away too quickly under the action of gravity after being poured on the measuring point grid, making it easy for the staff to have poor signal when using the flexible probe, resulting in a long monitoring operation time and low efficiency.

[0015] Optionally, the auxiliary monitoring component includes a pressing plate fixedly connected to the outer wall of the cushion plate, a baffle is fixedly connected to the side of the pressing plate, a slot is opened on the pressing plate near the connection of the flexible probe and the connecting pipe, and a sealing ring is fixedly connected to the slot.

[0022] Optionally, the elastic cord is made of an elastic material, and one end is fixedly connected to the middle position of the bottom of the baffle, and the other end is fixedly connected to the middle position of the outer wall of the plug column. The length of the elastic cord is greater than the length of the tube channel.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] In the above solution, through the auxiliary monitoring component, when the staff monitors the compactness of the concrete surface of the high-altitude tower column, the paving plate is clamped and installed on the flexible probe. After determining the position by drawing a grid at the conventional measurement points, the coupling agent is poured on the delivery pipe. Since the coupling agent has a certain viscosity, the falling and flowing speed is not fast. Then, when the coupling agent flows down inside the delivery pipe, manually press on the paving plate and slide the detection in cooperation with the falling coupling agent. At this time, the coupling agent will not be lost and affected by the high-altitude wind under the action of the overall structure of the paving plate. Therefore, when the staff is operating, it can ensure that the flexible probe is stable in monitoring the concrete compactness signal, improving the work efficiency.

[0025] By setting a pressing plate, a baffle, a connecting plate and a clamping plate in the auxiliary monitoring component, after a series of installations, the overall structure of the paving plate will be clamped on the flexible probe, effectively reducing the direct impact of the wind on the flexible probe. When the coupling agent falls, it can ensure that the coupling agent is also inside the overall structure of the paving plate, not easily flowing away by itself and being blown away by the wind. Further, when the pressing plate drives the flexible probe to slide, the bottoms of the pressing plate, the baffle and the connecting plate will first contact the curved surface of the tower column measurement point, and the coupling agent gathered at the bottom of the connecting plate can be evenly smeared on the curved surface of the tower column measurement point, effectively improving the use efficiency of the coupling agent, reducing the loss of the coupling agent caused by the wind and gravity, and improving the effective utilization of resources.

[0026] By setting the feed inlet, the discharge chute, the elastic cord, the pipe channel and the plug post, during the measurement at the measuring point, it is necessary to continuously slide back and forth, and more coupling agent gathered at the bottom of the connection plate can be evenly applied to the curved surface concrete of the tower column. At this time, more coupling agent can flow out, and by continuously sliding regularly, the uniformity of the coupling agent applied to the curved surface of the tower column can be improved. The size of the side baffle is two-thirds of that of the baffle, and a certain gap is left as an observation window to check the dosage of the coupling agent at the bottom of the connection plate, thereby improving the effective utilization of the coupling agent, also improving the uniformity of the coupling agent applied to the curved surface of the tower column, further improving the accuracy of the measurement and reducing the error.

[0049] Step 1. Preliminary preparation: Collect design materials, formulate a detection plan, prepare equipment such as an ultrasonic monitor, and polish and clean the detection surface;

[0053] Step 5. Key points of quality control: Control the environmental conditions, calibrate the equipment, and ensure the qualifications of the operators and the reliability of the detection;

[0054] Step Six, Engineering Case Reference: Actual projects have shown the combined use of multiple technologies and three-dimensional modeling for comparison.

[0055] In this embodiment, as Figures 1 to 12 shown, a connecting pipe 2 is installed on the outer wall of the ultrasonic monitor 1, and a flexible probe 3 is installed at the end of the connecting pipe 2. A cushion plate 4 is attached to the outer wall of the flexible probe 3, and a delivery pipe 5 is fixedly connected to the inner wall of the cushion plate 4; an auxiliary monitoring component is used to assist the staff in the monitoring operation at the top of the tower. The auxiliary monitoring component is connected to the cushion plate 4. In this application, the ultrasonic monitor 1, the connecting pipe 2, and the flexible probe 3 are disclosed as prior art and will not be elaborated here. The cushion plate 4 is exactly snapped onto the outer wall of the flexible probe 3, facilitating the staff to directly contact the cushion plate 4 instead of the flexible probe 3 during operation, reducing damage to the surface of the flexible probe 3. A number of clamping grooves with different sizes and shapes are provided on both sides of the cushion plate 4, and the delivery pipe 5 is fixed to the inner wall of the cushion plate 4. When the cushion plate 4 is installed and snapped, the delivery pipe 5 is also synchronously installed on the flexible probe 3.

[0056] Through the auxiliary monitoring component, when the staff monitors the density of the concrete surface of the high-altitude tower column, the cushion plate 4 is snapped onto the flexible probe 3. After determining the position by drawing a grid according to the conventional measuring points, the coupling agent is poured onto the delivery pipe 5. Since the coupling agent has a certain viscosity, its falling and flowing speed is not fast. Then, when the coupling agent flows down inside the delivery pipe 5, manually press on the cushion plate 4 to slide and detect in cooperation with the falling coupling agent. At this time, the coupling agent will not be lost and affected by the high-altitude wind under the action of the overall structure of the cushion plate 4. Thus, the staff can ensure that the flexible probe 3 monitors the concrete density signal stably during operation, improving work efficiency.

[0057] In this embodiment, as Figures 3 to 9As shown, the auxiliary monitoring component includes a pressing plate 401 fixedly connected to the outer wall of the laying plate 4. A baffle 402 is fixedly connected to the side of the pressing plate 401. A slot is provided on the pressing plate 401 near the connection between the flexible probe 3 and the connecting pipe 2, and a sealing ring 403 is fixedly connected to the slot. On both sides of the bottom of the pressing plate 401, connecting plates 404 are fixedly connected. In the middle of both sides of the laying plate 4, limiting plates 405 are fixedly connected. At the top of the inner wall of the pressing plate 401, a clamping plate 406 is fixedly connected. On both sides of the clamping plate 406, clamping rings 407 are fixedly connected. At the bottom of the clamping plate 406, a clamping piece 408 is fixedly connected. On the outer wall of the baffle 402 near the connecting pipe 2, a side baffle 409 is fixedly connected. On both sides of the inner wall of the pressing plate 401, friction pads 410 are fixedly connected. One side of the connecting plate 404 is fixedly connected to the side of the pressing plate 401, and the other side of the connecting plate 404 is fixedly connected to the side of the baffle 402, that is, one side of the connecting plate 404 is adapted to the side of the pressing plate 401, and the other side of the connecting plate 404 is adapted to the side of the baffle 402. The side baffle 409 is in an obtuse shape, and its shape is adapted to the shape of the side of the baffle 402. The friction pads 410 are made of rubber and are divided into upper and lower parts, and are both fixedly connected to the inner wall of the pressing plate 401. The baffle 402 is made of rubber and is integrally in an arc shape. The opening size of the sealing ring 403 is the same as the diameter size of the connecting pipe 2. The sizes of the clamping plate 406, the clamping rings 407, and the clamping piece 408 are sequentially adapted to the sizes of several clamping grooves on both sides of the laying plate 4.

[0058] With the above structure, before monitoring the compactness of concrete, the flexible probe 3 is placed at an angle suitable for picking up. Then, the bottom of the cushion plate 4 is aligned with the top of the flexible probe 3 and vertically snapped onto the outer wall of the flexible probe 3. The stability of the snap connection mainly depends on the friction pads 410 on both sides of the inner wall of the cushion plate 4. The friction between the friction pads 410 and both sides of the flexible probe 3 is relatively large, so that under normal use, the cushion plate 4 will not slide out from both sides of the flexible probe 3. Then, after the cushion plate 4 is stable, the pressing plate 401 is also vertically aligned with the top of the cushion plate 4. At the same time, the snap connection plate 406 is aligned with the snap connection grooves on both sides of the cushion plate 4. With the cooperation of the limiting plate 405, the snap connection plate 406 will not tilt outwards and fall off. After the snap connection is stable, the snap connection plate 406, the snap connection ring 407 and the snap connection piece 408 will all be in their respective snap connection grooves. At this time, the pressing plate 401 is in a stable state under the snap connection of the above three. During the operation, it is necessary to slide the flexible probe 3, so a certain pressure needs to be applied to the surface of the pressing plate 401. When applying the force, the snap connection plate 406 will have a slight tendency to slide downwards. Overall, it is manifested that the snap connection ring 407 is subjected to a downward extrusion force, and the snap connection piece 408 will also be subjected to a downward extrusion force. It is worth mentioning that when the snap connection piece 408 is downwardly extruded, that is, when the snap connection plate 406 as a whole slides deeper into the snap connection groove, the snap connection piece 408 will gradually change from an inclined state to a flat state, improving the snap connection effect. At this time, the stability is the strongest, and both the snap connection ring 407 and the snap connection piece 408 have a certain deformation ability. Finally, when the whole pressing plate 401 has not started working, it is also in a stable state. And after the snap connection is completed, the baffle 402, the connecting plate 404 and the side baffle 409 wrap the whole flexible probe 3, effectively reducing the wind force at high altitudes. Among them, the bottoms of the pressing plate 401, the baffle 402 and the connecting plate 404 are all provided with outer wrappings of flexible materials, and the pressing plate 401, the connecting plate 404 and the baffle 402 themselves are also made of flexible materials. After applying pressure to the pressing plate 401, the pressing plate 401, the baffle 402, the connecting plate 404 and the side baffle 409 can better improve the adaptability when contacting the curved surface of the tower column. And the working state after the flexible probe 3 and the cushion plate 4 are snap-connected is as Figure 12, at this time, one end of the connecting pipe 2 can be installed on the ultrasonic monitor 1, and the other end can be installed on the flexible probe 3. Before installing the flexible probe 3 on the connecting pipe 2, it is necessary to pass through the sealing ring 403 to ensure the normal operation of the equipment. Since the whole paving plate 4 is fixed on the outer wall of the flexible probe 3 by clamping, and the pressing plate 401, the baffle plate 402 and the connecting plate 404 are all of integral structure, the stability is high and the operation effect is obvious. Of course, the above-mentioned components are also convenient to replace. Except for the integral structure, the connections between the other components are all fixed by welding. Under the above series of installations, the overall structure of the paving plate 4 will be clamped on the flexible probe 3, thus effectively reducing the direct impact of the wind on the flexible probe 3. When the coupling agent drops, it can ensure that the coupling agent is also inside the overall structure of the paving plate 4 and is not easily lost independently or blown away by the wind. It is worth mentioning that after the coupling agent flows out, it will gather at the position of the connecting plate 404 as Figure 12 , because the working state of the flexible probe 3 is vertical and the surface of the tower column is curved, after using the structure of the paving plate 4, the coupling agent gathers at the bottom of the connecting plate 404. At this time, applying force on the pressing plate 401 to make the flexible probe 3 slide will cause the coupling agent gathered at the bottom of the connecting plate 404 to slide along with it. There will inevitably be residual coupling agent adhering to the measuring point surface of the tower column in the sliding track. Further, when the pressing plate 401 drives the flexible probe 3 to slide, the bottoms of the pressing plate 401, the baffle plate 402 and the connecting plate 404 will first contact the curved surface of the tower column measuring point, and the coupling agent gathered at the bottom of the connecting plate 404 can be evenly smeared on the curved surface of the tower column measuring point, thus effectively improving the use efficiency of the coupling agent, reducing the loss of the coupling agent caused by the wind and gravity, and improving the effective utilization of resources.

[0059] In this embodiment, as Figures 10 to 12 shown, one end of the delivery pipe 5 is fixedly connected with a feed inlet 501. A plurality of blanking grooves 502 are formed on the outer wall of the delivery pipe 5. A retaining piece 503 is clamped on the inner wall of the feed inlet 501. A elastic cord 504 is fixedly connected to the middle position at the bottom of the retaining piece 503. A pipe channel 505 is fixedly connected to the outer wall of the elastic cord 504. The end of the elastic cord 504 far from the retaining piece 503 is fixedly connected with a plug column 506. A hollow circular pipe 507 is fixedly connected to the inner wall of the delivery pipe 5 far from the feed inlet 501. A liquid outlet 508 is formed at the end of the delivery pipe 5 far from the feed inlet 501. The elastic cord 504 is made of elastic material, with one end fixedly connected to the middle position at the bottom of the retaining piece 503 and the other end fixedly connected to the middle position on the outer wall of the plug column 506. The length of the elastic cord 504 is greater than the length of the pipe channel 505. The blanking grooves 502 are formed on the outer wall of the delivery pipe 5 and are arrayed at the bottom of the delivery pipe 5 and distributed along the shape of the delivery pipe 5. A smooth film is coated on the inner wall of the delivery pipe 5, which improves the sliding effect of the plug column 506 on the one hand and prevents the coupling agent from sticking to the inner wall of the delivery pipe 5 when it enters on the other hand.

[0060] With the above structure, when the backing plate 4 is stably clamped on the flexible probe 3, it means that the delivery pipe 5 is also in a stable state. At this time, after the measured point curved surface grid of the tower column is drawn, the coupling agent is poured in from the feed port 501. The amount poured is mainly based on the contact distance between the flexible probe 3 and the coupling agent in the existing data. Then the coupling agent flows into the delivery pipe 5 along it. After flowing for a period of time, it will contact the plug 506. Since the internal friction between the plug 506 and the delivery pipe 5 is relatively low, under the action of the gravity and acceleration of the coupling agent, it will slide towards the hollow circular pipe 507. During the sliding process, the coupling agent will flow out from the blanking groove 502. The blanking grooves 502 are distributed at the bottom of the delivery pipe 5 and are evenly arranged in an array along the shape of the delivery pipe 5. The flowing coupling agent will continue to flow along the inner wall of the baffle 402 to the bottom of the connecting plate 404 to gather. After pouring the coupling agent, a short waiting time is required because the coupling agent has a certain viscosity and at this time it has not carried the plug 506 to slide to the hollow circular pipe 507. After waiting for a period of time, the coupling agent will appear on the inner wall of the baffle 402. At this time, pressure can be applied to the pressing plate 401 to drive the flexible probe 3 to slide at each measured point. And during the sliding process, the plug 506 is also sliding towards the hollow circular pipe 507, and the coupling agent will also flow out from each blanking groove 502. Inevitably, a small amount of residual coupling agent will flow into the hollow circular pipe 507 through the plug 506 during the sliding process. After the plug 506 reaches the hollow circular pipe 507, the residual coupling agent will flow into the bottom of the liquid outlet 508 along the hollow position in the middle of the hollow circular pipe 507 and then flow out. Since the overall shape of the delivery pipe 5 is bent downward, the coupling agent can easily flow out of the delivery pipe 5, and very little coupling agent will accumulate inside the delivery pipe 5. When the loss amount of the coupling agent inside the delivery pipe 5 is lower than the elastic force of the pipe channel 505, the pipe channel 505 will rebound. Under the action of the rebound, a very small amount of residual coupling agent will be slid back to the initial position by the plug 506 together, that is, the coupling agent is concentrated on the surface of the plug 506. The cleaning method is to directly take out the retaining piece 503. At this time, the elastic cord 504, the pipe channel 505 and the plug 506 fixed at the bottom of the retaining piece 503 will all be taken out together, and each component can be cleaned and reused. It is worth mentioning that during the process of measuring points, it is necessary to slide back and forth continuously, and more coupling agent gathered at the bottom of the connecting plate 404 can be evenly smeared on the curved surface concrete of the tower column. And different pressures applied to the pressing plate 401 can also change the amount of coupling agent flowing out from the connecting plate 404. That is, when the pressure applied to the pressing plate 401 is reduced, the contact effect between the bottom of the pressing plate 401, the baffle 402 and the connecting plate 404 and the curved surface of the tower column is reduced, the gap increases, and at this time more coupling agent can flow out. Continuously slide regularly to improve the uniformity of the coupling agent smeared on the curved surface of the tower column. And the size of the side baffle 409 is two-thirds of that of the baffle 402, and there is a certain gap that can be used as an observation window to check the amount of coupling agent at the bottom of the connecting plate 404.Thus, the effective utilization of the coupling agent is improved, and the uniformity of the coupling agent applied on the curved surface of the tower column is also improved, thereby improving the accuracy of measurement and reducing errors.

[0061] The working principle of the technical solution provided by the present invention is as follows:

[0062] Before monitoring the compactness of concrete, the flexible probe 3 is placed at an angle suitable for picking up, and then the bottom of the paving plate 4 is aligned with the top of the flexible probe 3 and vertically snapped onto the outer wall of the flexible probe 3. The stability of the snap connection mainly depends on the friction pads 410 on both sides of the inner wall of the paving plate 4. The friction between the friction pads 410 and both sides of the flexible probe 3 is relatively large, so that under normal use, the paving plate 4 will not slide out from both sides of the flexible probe 3. Then, after the paving plate 4 is stable, the pressing plate 401 is also vertically aligned with the top of the paving plate 4, and at the same time, the snap connection plate 406 is aligned with the snap connection grooves on both sides of the paving plate 4. With the cooperation of the limiting plate 405, the snap connection plate 406 will not tilt outwards and fall off. After the snap connection is stable, the snap connection plate 406, the snap connection ring 407 and the snap connection piece 408 will all be in their respective snap connection grooves. At this time, the pressing plate 401 is in a stable state under the snap connection of the above three components. During the operation, it is necessary to slide the flexible probe 3, so a certain pressure needs to be applied to the surface of the pressing plate 401. When applying the force, the snap connection plate 406 will have a slight tendency to slide downwards. Overall, it is manifested that the snap connection ring 407 is subjected to a downward extrusion force, and the snap connection piece 408 will also be subjected to a downward extrusion force. It is worth mentioning that when the snap connection piece 408 is extruded downwards, that is, when the snap connection plate 406 slides deeper into the snap connection groove as a whole, the snap connection piece 408 will gradually change from an inclined state to a flat state, improving the snap connection effect. At this time, the stability is the strongest, and both the snap connection ring 407 and the snap connection piece 408 have a certain deformation ability. Finally, the entire pressing plate 401 is in a stable state before the operation starts, and after the snap connection is completed, the baffle plate 402, the connecting plate 404 and the side baffle plate 409 wrap the entire flexible probe 3, effectively reducing the wind force at high altitudes. The bottoms of the pressing plate 401, the baffle plate 402 and the connecting plate 404 are all provided with an outer wrapping of flexible material, and the pressing plate 401, the connecting plate 404 and the baffle plate 402 themselves are also made of flexible material. After applying pressure to the pressing plate 401, the pressing plate 401, the baffle plate 402, the connecting plate 404 and the side baffle plate 409 can better improve the adaptability when contacting the curved surface of the tower column. The working state after the flexible probe 3 and the paving plate 4 are snap-connected is as Figure 12, at this time, one end of the connecting pipe 2 can be installed on the ultrasonic monitor 1, and the other end can be installed on the flexible probe 3. Before installing the flexible probe 3 on the connecting pipe 2, the sealing ring 403 is required to ensure the normal operation of the equipment. Since the whole paving plate 4 is fixed on the outer wall of the flexible probe 3 by snap connection, and the pressing plate 401, the baffle plate 402 and the connecting plate 404 are all of integral structure, the stability is high and the operation effect is obvious. Of course, the replacement of the above-mentioned components is also convenient. Except for the integral structure, the connection between the remaining components is fixed by welding. Under the above series of installations, the whole structure of the paving plate 4 will be snap-connected on the flexible probe 3, thus effectively reducing the direct influence of wind on the flexible probe 3, so that when the coupling agent falls, it can be ensured that the coupling agent is also inside the whole structure of the paving plate 4 and is not easily lost independently or blown away by the wind. It is worth mentioning that after the coupling agent flows out, it will gather at the position of the connecting plate 404 as Figure 12 , because the working state of the flexible probe 3 is vertical and the surface of the tower column is curved, after using the structure of the paving plate 4, the coupling agent gathers at the bottom of the connecting plate 404. At this time, when a force is applied to the pressing plate 401 to make the flexible probe 3 slide, the coupling agent gathered at the bottom of the connecting plate 404 will also slide accordingly. There will inevitably be residual coupling agent attached to the measured surface of the tower column in the sliding track. Further, when the pressing plate 401 drives the flexible probe 3 to slide, the bottoms of the pressing plate 401, the baffle plate 402 and the connecting plate 404 will first contact the measured surface of the tower column, and the coupling agent gathered at the bottom of the connecting plate 404 can be evenly smeared on the measured surface of the tower column, thus effectively improving the use efficiency of the coupling agent and reducing the loss of the coupling agent caused by wind and gravity, and improving the effective utilization of resources.

[0063] When the backing plate 4 is stably clamped on the flexible probe 3, it means that the delivery pipe 5 is also in a stable state. At this time, after the measured point curved surface grid of the tower column is drawn, the coupling agent is poured from the feed port 501. The poured dosage is mainly based on the contact distance between the flexible probe 3 and the coupling agent in the existing data. Then the coupling agent flows into the delivery pipe 5 along it. After flowing for a period of time, it will contact the plug column 506. Since the internal friction between the plug column 506 and the delivery pipe 5 is relatively low, under the action of the gravity and acceleration of the coupling agent, it will slide towards the hollow circular pipe 507. During the sliding process, the coupling agent will flow out from the material discharge groove 502. The material discharge grooves 502 are distributed at the bottom of the delivery pipe 5 and are evenly distributed in an array along the shape of the delivery pipe 5. The flowing-out coupling agent will continue to flow along the inner wall of the baffle 402 to the bottom of the connecting plate 404 to gather. After pouring the coupling agent, a short period of waiting is required. The purpose of waiting is because the coupling agent has a certain viscosity and has not yet carried the plug column 506 to slide to the hollow circular pipe 507 at this time. After waiting for a period of time, the coupling agent will appear on the inner wall of the baffle 402. At this time, pressure can be applied to the pressing plate 401 to drive the flexible probe 3 to slide at each measured point. And during the sliding process, the plug column 506 is also sliding towards the hollow circular pipe 507, and the coupling agent will also flow out from each material discharge groove 502. Inevitably, a small amount of residual coupling agent will flow into the hollow circular pipe 507 through the plug column 506 during the sliding process. After the plug column 506 reaches the hollow circular pipe 507, the residual coupling agent will flow into the bottom of the liquid outlet 508 along the hollow position in the middle of the hollow circular pipe 507 and then flow out. Since the overall shape of the delivery pipe 5 is bent downward, the coupling agent is very easy to flow out of the delivery pipe 5, and very little coupling agent will accumulate inside the delivery pipe 5. When the loss amount of the coupling agent inside the delivery pipe 5 is lower than the elastic force of the pipe channel 505, the pipe channel 505 will rebound. Under the action of the rebound, a very small amount of residual coupling agent will be slid back to the initial position by the plug column 506 together, that is, the coupling agent is concentrated on the surface of the plug column 506. The cleaning method is to directly take out the baffle 503. At this time, the elastic cord 504, the pipe channel 505 and the plug column 506 fixed at the bottom of the baffle 503 will all be taken out together, and each component can be cleaned and reused. It is worth mentioning that during the process of measuring points, it is necessary to continuously slide back and forth, and more coupling agent gathered at the bottom of the connecting plate 404 can be evenly smeared on the curved surface concrete of the tower column. And different pressures applied to the pressing plate 401 can also change the dosage of the coupling agent flowing out from the connecting plate 404. That is, when the pressure applied to the pressing plate 401 is reduced, the contact effect between the bottom of the pressing plate 401, the baffle 402 and the connecting plate 404 and the curved surface of the tower column is reduced, and the gap increases. At this time, more coupling agent can flow out. Continuously slide regularly to improve the uniformity of the coupling agent smeared on the curved surface of the tower column. And the size of the side baffle 409 is two-thirds of that of the baffle 402, and a certain gap is left as an observation window to check the dosage of the coupling agent at the bottom of the connecting plate 404, thereby improving the effective utilization of the coupling agent.It also improves the uniformity of the coupling agent applied to the surface of the tower column, thereby improving the accuracy of measurement and reducing errors.
