Description

Technical Field

[0001] The present invention relates to the technical field of verticality detection of foundation pit excavation, and in particular to a rapid verticality detection component and method for foundation pit excavation. Background Art

[0002] A foundation pit is a pit excavated at the designed foundation location according to the base elevation and plan dimensions. Foundation pit excavation involves the excavation and removal of soil at the construction site, either mechanically or manually, in accordance with design requirements, to prepare for subsequent construction. The depth and shape of the excavation typically depend on the building's design requirements. In construction projects, the verticality of the foundation pit is crucial to project safety and quality. Inaccurate verticality can lead to serious problems such as foundation pit collapse and settlement of surrounding buildings.

[0003] In the prior art, when testing the verticality of the foundation pit excavation surface, the traditional testing method is to use the manual hanging line method, that is, select two fixed points at the top of the foundation pit, fix one end of the hanging line on a top fixed point, let the plumb line droop naturally, and the staff use a steel ruler to measure the distance between the plumb line and the foundation pit excavation surface at different heights, and compare the distance between the plumb line and the foundation pit excavation surface at different heights. If the distance difference is small, it means that the verticality of the foundation pit wall is good; if the difference is large, it indicates that there is a problem with the verticality. The traditional verticality detection method is highly dependent on manual labor. When the staff uses a steel ruler to measure, they are greatly affected by manual labor, such as inaccurate line of sight angles, non-vertical placement of the steel ruler, etc., which will lead to errors in the readings, thereby affecting the measurement accuracy and the accuracy of the test results.

[0004] Therefore, we propose a rapid verticality detection component for foundation pit excavation in order to solve the problems raised in the above background technology. Summary of the Invention

[0016] The method for using the verticality rapid detection component for foundation pit excavation includes the following steps:

[0017] S1. Push the first inspection plate, insert the second ground nail into the interior of the foundation pit to fix it, then align the card block with the card slot and push the second inspection plate to install the second inspection plate, and then install another second inspection plate;

[0018] S2. Use the mobile vehicle to push the verticality detection assembly to the upper level of the second detection plate, start the forward and reverse motors, and drive the rotating plate to rotate 180 degrees, so that the laser transmitter rotates from the inside of the mobile vehicle to the upper part of the foundation pit;

[0019] S3. Start the laser transmitter to emit a vertical laser beam. According to the position of the laser line, insert the first vertical plate into the bottom surface of the foundation pit body and fix it. Then insert the splicing plate into the splicing groove to install the second vertical plate on top of the first vertical plate. Then install another second vertical plate.

[0020] S4. Place the balance detection plate between the second vertical plate and the second detection plate, and slide the two detection guide wheels into the first detection slot and the second detection slot.

[0021] S5. The first detection slot always remains vertical. When the second detection slot is also vertical, the two detection guide wheels will remain horizontal and move downward.

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

[0024] 1. When the present invention is used, the balance detection plate is placed between the second vertical plate and the second detection plate, and the two detection guide wheels are made to slide into the first detection groove and the second detection groove, the winding motor is started, and the winding roller is driven to rotate slowly through the output end of the winding motor to release the winding rope, so that the two detection guide wheels roll downward along the inner walls of the first detection groove and the second detection groove respectively, and the first detection groove always remains vertical. When the second detection groove is also in a vertical state, the two detection guide wheels will maintain a horizontal state and move downward. When the first detection groove is in an inclined state, the balance detection plate will gradually tilt under the active connection of the movable ball and the lifting ring, and the inclination sensor will detect the tilt of the balance detection plate. After measuring the inclination angle of the balance detection plate, the data acquisition module collects data and transmits the data to the data processing module for processing and analysis. The PLC controller records and stores the data in real time. The display on the console allows the detection personnel to see the inclination data. According to the detection data, the inclination condition of the inner wall of the foundation pit can be judged, and the slight verticality deviation can be accurately measured, thereby completing the rapid detection of the verticality of the foundation pit surface, greatly improving the detection efficiency. With the cooperation of the data acquisition component and the verticality detection component, automatic verticality detection is realized without excessive human intervention, reducing human errors, and at the same time, the detection results can be fed back in real time, facilitating timely measures.

[0025] 2. When the present invention is used, push the first detection plate, insert the second ground nail into the interior of the foundation pit body for fixation, then align the card block with the card slot, and push the second detection plate, install the second detection plate, and then install another second detection plate. At this time, the first detection plate and the second detection plate are parallel to the inner wall of the foundation pit body, start the laser emitter, and emit a vertical laser beam. According to the position of the laser line, insert the first vertical plate into the bottom surface of the inside of the foundation pit body for fixation, and then insert the splicing plate into the splicing groove, so that the second vertical plate is installed on the top of the first vertical plate, and then install another second vertical plate. At this time, the first vertical plate and the two second vertical plates remain in a vertical state, which is convenient for the subsequent verticality detection component to detect the vertical condition of the inner wall of the foundation pit body.

[0026] 3. When the present invention is used, the first vertical plate and the second vertical plate are formed by splicing, and the first detection plate and the second detection plate are formed by splicing.

[0040] In this embodiment, when in use, the console 303, the data acquisition module 308, the data processing module 310, the PLC controller 309, the winding motor 402, the inclination sensor 412, the laser emitter 413, the forward and reverse motor 415 and the battery 307 are electrically connected, and the battery 307 is used to power other devices. The console 303 sends an operation instruction to the PLC controller 309, and then the PLC controller 309 controls the corresponding device to work according to the received operation instruction. Four universal wheels with built-in brake pads are installed at the bottom of the mobile vehicle 301. The first detection plate 206 and the second detection plate 207 are installed on the inner wall of the foundation pit body 1 through the splicing component 2. At this time, the first detection plate 206 and the second detection plate 207 are parallel to the inner wall of the foundation pit body 1. When the inner wall of the foundation pit body 1 is relatively vertical, the first detection plate 206 and the second detection plate 207 are relatively vertical. When the inner wall of the foundation pit body 1 is relatively inclined, the first detection plate 206 and the second detection plate 207 are also inclined, so that the first detection groove 211 is inclined. The verticality detection component 4 is moved to the horizontal upper side of the second detection plate 207 by the mobile vehicle 301, and the forward and reverse motors 415 are started. The output end of the forward and reverse motors 415 drives the rotating plate 401 to rotate 180 degrees, so that the laser emitter 413 rotates from the inside of the mobile vehicle 301 to the upper side of the inside of the foundation pit body 1.

The winding roller 403 is driven to rotate slowly through the output end of the winding motor 402, and the winding rope 404 is slowly released, so that it moves slowly downward inside the protective cover 418. As the winding rope 404 is released, the balance detection plate 407 moves slowly downward, driving the two detection guide wheels 410 to roll downward along the inner wall of the first detection groove 211 and the inner wall of the second detection groove 212 respectively.

When the second detection groove 212 is also vertical, the two detection guide wheels 410 will maintain a horizontal state and move downward in the first detection groove 211 and the second detection groove 212. When the first detection groove 211 is in a tilted state, the movable ball 406 and the lifting ring 405 are connected, and the balance detection plate 407 will gradually tilt. At the same time, the inclination sensor 412 will detect the inclination angle of the balance detection plate 407 and transmit the detected inclination data to the data acquisition module in the form of an electrical signal. Block 308 performs data acquisition, and then the data acquisition module 308 transmits the inclination data to the data processing module 310 for processing and analysis, and then transmits the data to the PLC controller 309 for real-time recording and storage. The inclination data can be conveniently viewed by the inspection personnel through the display on the console 303. The inclination condition of the inner wall of the foundation pit body 1 can be judged according to the detection data, and the slight verticality deviation can be accurately measured, thereby completing the rapid detection of the verticality of the foundation pit surface, greatly improving the detection efficiency. With the cooperation of the data acquisition component 3 and the verticality detection component 4, automatic verticality detection is realized without excessive human intervention, reducing human errors, and at the same time, the detection results can be fed back in real time, facilitating timely measures, solving the problem of using the manual hanging line method for verticality detection of the foundation pit excavation surface, which is highly dependent on manual labor. When the staff uses a steel ruler to measure, they are greatly affected by manual labor, such as inaccurate line of sight angle, non-vertical placement of the steel ruler, etc., which will cause errors in the readings, thereby affecting the measurement accuracy and the accuracy of the detection results.

When the winding rope 404 moves up and down inside the protective cover 418, the winding rope 404 is protected by the protective cover 418 to reduce wear and increase service life.

[0043] The usage and working principle of the present invention are as follows: first, place the first detection plate 206 on the inner wall of the foundation pit body 1 to be tested for verticality, then push the first detection plate 206 so that the second ground nails 208 on the rear surface of the first detection plate 206 are inserted into the interior of the foundation pit body 1, fix the first detection plate 206 on the inner wall of the foundation pit body 1, then place the second detection plate 207 on the first detection plate 206, and align the two card blocks 210 with the two card slots 209, then push the second detection plate 207 so that the second ground nails 208 on the rear surface are inserted into the inner wall of the foundation pit body 1, at this time, the two card blocks 210 are just stuck in the two card slots 209, and the bottom of the second detection plate 207 falls on the top of the first detection plate 206, then follow the second detection plate 207, as shown in FIG. Figure 2As shown, at this time, the three first detection grooves 211 are connected and in a straight line. The first detection plate 206 and the two second detection plates 207 are parallel to the inner wall of the foundation pit body 1. The verticality detection component 4 is moved to the horizontal position above the second detection plate 207 by the mobile vehicle 301, and the forward and reverse motors 415 are started. The output end of the forward and reverse motors 415 drives the rotating plate 401 to rotate 180 degrees, so that the laser emitter 413 rotates from the inside of the mobile vehicle 301 to the top of the inside of the foundation pit body 1. The laser emitter 413 is started to emit a laser beam to the bottom surface of the inside of the foundation pit body 1. According to the laser line In the vertical direction, the first vertical plate 201 is inserted into the bottom surface of the foundation pit body 1, so that the first ground nail 203 is inserted into the foundation pit body 1 to fix the first vertical plate 201, and then the splicing plate 205 at the bottom of one of the second vertical plates 202 is inserted into the splicing groove 204 at the first vertical plate 201, so that one of the second vertical plates 202 is installed on the top of the first vertical plate 201, and then the other second vertical plate 202 is installed. At this time, the first vertical plate 201 and the two second vertical plates 202 remain in a vertical state, and the three second detection grooves 212 are connected and maintain a straight line.Then, the balance detection plate 407 is placed between the second vertical plate 202 and the second detection plate 207, and the two detection guide wheels 410 slide into the first detection groove 211 and the second detection groove 212. At this time, the balance detection plate 407 remains in a horizontal state, and the winding motor 402 is started. The winding roller 403 is driven to rotate slowly through the output end of the winding motor 402, and the winding rope 404 is slowly released, so that it moves slowly downward inside the protective cover 418. As the winding rope 404 is released, the balance detection plate 407 slowly moves downward, driving the two detection guide wheels 410 to roll downward along the inner wall of the first detection groove 211 and the inner wall of the second detection groove 212 respectively. The first detection groove 211 always remains vertical. When the second detection groove 212 is also vertical, the two detection guide wheels 410 will remain horizontal and move downward in the first detection groove 211 and the second detection groove 212. When the first detection groove 211 is in a tilted state, between the movable ball 406 and the hanging ring 4 05's active connection will cause the balance detection plate 407 to gradually tilt, and at the same time, the inclination sensor 412 will detect the inclination angle of the balance detection plate 407, and transmit the detected inclination data to the data acquisition module 308 in the form of an electrical signal for data acquisition, and then the data acquisition module 308 will transmit the inclination data to the data processing module 310 for processing and analysis, and then transmit the data to the PLC controller 309 for real-time recording and storage. The display on the console 303 is convenient for the detection personnel to see the inclination data, and the inclination condition of the inner wall of the foundation pit body 1 can be judged according to the detection data, and the slight verticality deviation can be accurately measured, thereby completing the rapid detection of the verticality of the foundation pit surface, greatly improving the detection efficiency, and with the cooperation of the data acquisition component 3 and the verticality detection component 4, automatic verticality detection is realized without excessive human intervention, reducing human errors, and at the same time, the detection results can be fed back in real time, so that timely measures can be taken.

[0044] Among them, the console 303, battery 307, data acquisition module 308, data processing module 310, PLC controller 309, winding motor 402, tilt sensor 412, laser emitter 413 and forward and reverse motor 415 are all existing technologies, and their components and usage principles are all public technologies, so no further explanation will be given here.
