Description

Technical Field

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

[0002] The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Foundation pit excavation refers to the excavation and cleaning of soil at the construction site according to the design requirements using mechanical equipment or manual methods to prepare for subsequent construction. The depth and shape of the excavation usually depend on the design requirements of the building. In construction projects, the verticality of the foundation pit excavation is crucial to the safety and quality of the project. Inaccurate verticality may lead to serious problems such as foundation pit collapse and settlement of surrounding buildings.

[0003] In the prior art, when the excavation surface of a foundation pit is tested for verticality, the traditional detection method is to use the manual hanging line method, that is, to 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 difference in distance 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 cause errors in the readings, thereby affecting the measurement accuracy and the accuracy of the detection results.

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 pushed to move to the upper level of the second detection plate 207 through 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 part of the inside of the foundation pit body 1, as shown in FIG.

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 first detection groove 211 is in an inclined state, under the active connection between the movable ball 406 and the lifting ring 405, the balance detection plate 407 will gradually become inclined. 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 display on the console 303 is convenient for the detection personnel to see the inclination data. 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, which is convenient for timely measures to be taken, and the problem of using the manual hanging line method for verticality detection of the foundation pit excavation surface is solved. The manual dependence on manual labor is very large. 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 method 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 where the verticality is to be detected, 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, and 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 state, the first detection plate 206 and the two second detection plates 207 are parallel to the inner wall of the foundation pit body 1, and the verticality detection component 4 is pushed to move 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 rotating plate 401 is driven to rotate 180 degrees according to the output end of the forward and reverse motors 415, 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, and 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, and the first vertical plate 201 is fixed, 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 another second vertical plate 202 is installed. At this time, the first vertical plate 201 and the two second vertical plates 202 maintain a vertical state, and the three second detection grooves 212 are connected to maintain a straight line state.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 are made to 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 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. The first detection groove 211 always remains vertical. When the second detection groove 212 is also in a vertical state, 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, between the movable ball 406 and the hanging ring 4 05, the balance detection plate 407 will gradually tilt, and 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 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, and 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, so as to complete the rapid detection of the verticality of the foundation pit surface, which greatly improves the detection efficiency, and with the cooperation of the data acquisition component 3 and the verticality detection component 4, the verticality automatic detection is realized without excessive human intervention, which reduces human errors, and can also feedback the detection results in real time, so as to facilitate timely measures.
