Bridges are important infrastructure in the development of the national economy and are of great significance to the development of the national economy and the improvement of people's living standards.

[0003] During bridge construction, different geological conditions will be encountered, often complex geological conditions. Complex geological conditions will cause the construction progress of bridge pile foundation to lag behind. Inadequate detection during the process will affect the subsequent construction judgment, leading to major safety problems such as bridge settlement, bridge deck fracture, and collapse. Bridge construction generally uses advanced drilling for pre-construction survey to explore the geological conditions of the pile foundation, determine the elevation of the pile bottom, and collect cave imaging and other information. This technical measure brings many benefits to the project, such as construction quality assurance, accelerated construction progress, and investment savings.

The trolley 2 can adjust its position as needed, and the support plate 1 can be straddled above the borehole to provide a stable support foundation. Various sensors can be installed in the detection module 505 according to measurement needs, such as laser sensors, camera motion high-definition sensors, ranging sensors, sonar sensors, high-precision three-dimensional laser scanning sensors and laser radar coordinate scanning sensors, etc. The sensors cooperate with each other to obtain relatively complete and accurate information inside the hole.

[0043] In a preferred solution, a slideway 101 is provided through the support plate 1, and two rollers 201 are symmetrically provided on both sides of the trolley 2, the rollers 201 are slidably connected to the slideway 101, and a first limiting wheel 203 is rotatably provided between the two rollers 201 on the same side, and the first limiting wheel 203 abuts against the inner side of the slideway 101. With this structure, the movement and adjustment of the trolley 2 are convenient, and the first limiting wheel 203 prevents the problem of movement jam.

[0044] In the preferred solution, a through slot 102 is provided in the slideway 101, a first through hole 103 is provided at one end of the through slot 102, the cable 3 is passed through the first through hole 103, a screw 6 is detachably provided on one side of the slideway 101 close to the first through hole 103, the first limiting wheel 203 is rotatably provided on the boss 202, the boss 202 is located between the two rollers 201 on the same side, and the screw 6 abuts against the side wall of the boss 202.

A level is arranged on the upper part of the trolley 2, and with this structure, when the trolley 2 is fixed in a suitable position, the height of each stud 105 can be adjusted, so that the support plate 1 can be kept in a relatively horizontal state, which is conducive to the high accuracy of the subsequent lowering of the detector 5 and the more balanced overall force.

[0046] In the preferred embodiment, the driving wheel 401 is connected to the output shaft 407 through the first motor 408, and the output shaft 407 is arranged in the trolley 2. The first baffle 402 and the second baffle 403 are respectively provided on both sides of the driving wheel 401. An annular groove 404 is provided between the first baffle 402 and the second baffle 403. The two annular grooves 404 cooperate to form a clamping space 405. The outer diameter of the first baffle 402 is larger than the outer diameter of the second baffle 403. A first threaded hole 204 is provided on the upper part of the trolley 2. The first threaded hole 204 is connected to a guide cylinder 7 through a screw 6. The guide cylinder 7 includes a sleeve 701 and a mounting plate 702. The cable 3 is inserted into the sleeve 701, and the sleeve 701 is arranged directly above the clamping space 405. With this structure, the state of the first motor 408 can be controlled as needed. Any one of the first motors 408 can be locked and the other motor 408 can work. Alternatively, the two motors 408 can work at the same time and rotate in opposite directions. The first motor 408 adopts a servo motor, and the overall control accuracy and output torque are stable. The two annular grooves 404 are in contact with the cable 3, which play a role of friction drive and locking. At the same time, in order to ensure that the cable 3 entering the top of the driving wheel 401 is vertical, the sleeve 701 of the guide cylinder 7 can play a role of pre-guiding, ensuring high accuracy during lowering, more stable state of the detector 5, more stable operation of each sensor of the detection module 505, and higher value of the obtained numerical value, which is convenient for faster analysis and judgment results in the later stage.

[0047] In the preferred solution, a column 406 is provided outside the second baffle 403, and the two columns 406 are connected by a limiting plate 8, and the limiting plate 8 includes two second through holes 801 arranged opposite to each other, and a clamping block 802 is provided between the two second through holes 801, and the clamping block 802 is located between the two second baffles 403, and the column 406 is passed through the second through holes 801, and the second baffle 403 is connected to the limiting plate 8 by a locking ring 803. With this structure, the two driving wheels 401 cooperate with each other, and the limiting plate 8 fixes the distance between the two driving wheels 401, so as to keep the clamping effect of the annular groove 404 on the cable 3 relatively balanced and stable, and avoid the problem of shaking.

[0048] In the preferred embodiment, an anti-collision ring 9 is provided on the outside of the detector 5, and the anti-collision ring 9 includes a support frame 901, and the support frame 901 is connected to the detector 5 through multiple connecting rods 902. A second threaded hole 905 is provided on the support frame 901, and the support frame 901 is connected to a push rod 903 through a screw 6. A second limiting wheel 904 is rotatably provided at the bottom of the push rod 903, and the second limiting wheel 904 abuts against the inner wall of the borehole. With this structure, the overall lowering is smooth and efficient. Since the drilling state inside the borehole is not the same and is subject to interference from the external environment, the jitter of the cable 3 will directly affect the measuring state of the detector 5. The anti-collision ring 9 protects the relatively small moving range of the detector 5, and the second limiting wheel 904 provided can play a guiding and limiting role. Only when the posture of the detector 5 is stable can the camera therein obtain relatively stable imaging. At this time, the information in the borehole can be transmitted to the external control terminal intuitively and accurately. At the same time, the operation of the high-precision three-dimensional laser scanner also requires a stable state. The use of the anti-collision ring 9 more efficiently provides a guarantee for the stable operation of the detector 5.

[0049] In a preferred embodiment, the detector 5 includes a first space 501, a second space 502 and a third space 503 arranged from top to bottom, an axis 507 is arranged in the first space 501 and the second space 502, a control unit 504 is arranged in the first space 501, a plurality of detection modules 505 are arranged circumferentially in the second space 502, a gyroscope 506 is arranged in the third space 503, a cleaning unit 10 is arranged on the outside of the detector 5, the cleaning unit 10 includes a circular frame 1002, the circular frame 1002 is slidably connected to the outer wall of the detector 5 through a ball 1003, a brush head 1001 is arranged on the circular frame 1002, the circular frame 1002 is connected to the second motor 1006 through a plurality of pull ropes 1004, the plurality of pull ropes 1004 are symmetrically arranged on the circular frame 1002, the second motor 1006 is arranged on the upper and lower sides of the detector 5, and a fixed pulley 1005 for convenient steering is also provided, and the fixed pulley 1005 is fixed on the detector 5. With this structure, the first space 501, the second space 502 and the third space 503 cooperate with each other, the gyroscope 506 plays the role of correcting deviation and maintaining steady state, and can also play the role of counterweight, the shaft 507 ensures the structural strength of the detector 5, and the overall bearing capacity is better, four second motors 1006 are provided, two second motors 1006 are relatively installed on the upper side of the detector 5, and two second motors 1006 are relatively installed on the lower side of the detector 5, and the second motors 1006 on the upper and lower sides are kept in a vertically arranged state, and the pull rope 1004 can be retracted and released by the two second motors 1006 using the fixed pulley 1005, so as to change the pull rope 1004 The position of the circular frame 1002, in the initial state, the circular frame 1002 is arranged at the lower part of the detector 5. When the outer surface of the detector 5 needs to be cleaned and dusted, the two second motors 1006 on the upper side tighten the pull rope 1004, and the two second motors 1006 on the lower side loosen the pull rope 1004. Each second motor 1006 maintains the same rotation frequency, so that the circular frame 1002 can be smoothly shifted. A transparent panel is arranged on the outside of the second space 502 of the detector 5. The camera of the detection module 505 can observe the information in the hole through the transparent panel. The brush head 1001 adopts a dust-cleaning cloth, and the overall dust removal effect is better, and the dust generated by wiping is relatively less.

[0050] In the preferred solution, a transparent partition 508 is further provided in the second space 502, a cover plate 509 is provided on the outside of the transparent partition 508, the cover plate 509 is slidably arranged on the detector 5, an extension support 510 is provided at the lower part of the cover plate 509, the extension support 510 abuts against the lower part of the circular frame 1002, and an avoidance groove 511 is further provided in the third space 503, a spring 512 is fixed in the avoidance groove 511, the spring 512 is supported at the lower part of the extension support 510, and the cover plate 509 is driven to move downward by pulling down the circular frame 1002, thereby forming a gap 513 in cooperation with the second space 502 The notch 513 is arranged in front of the detection module 505, and also includes a dust suction unit 11 arranged on the detector 5, the dust suction unit 11 includes an air inlet 1101 and an air outlet 1102, the air outlet 1102 is closer to the center of the detector 5, the air outlet 1102 is connected to an air outlet pipe 1103, the air outlet pipe 1103 is symmetrically provided with a diversion pipe 1104, the diversion pipe 1104 is arranged in the first space 501 and the second space 502, the diversion pipe 1104 is located on the outside of the transparent partition 508, and a plurality of fine holes 1105 are provided on the diversion pipe 1104. Due to the change of the external environment, there is a lot of floating dust in the borehole, and it is difficult to ensure that the detector 5 will not collide or interfere with the side wall during random placement. The floating dust will affect the measurement effect and accuracy. The air inlet 1101 of the dust suction unit 11 generates negative pressure to quickly absorb the floating dust in the borehole. A filter element is arranged in the dust suction unit 11 to better collect the floating dust. At the same time, the air outlet 1102 blows air to one side of the transparent partition 508 of the second space 502 to form a stable positive pressure to ensure that external floating dust will not enter. When the second motor 1006 located at the lower side of the detector 5 works, the cover 509 slides down and the second space 502 is opened. The camera in the detection module 505 takes pictures with high clarity and good imaging effect. When the shooting is completed, the second motor 1006 is released, and the cover 509 is reset under the action of the spring 512 to ensure the closure of the second space 502. Then the dust suction unit 11 is closed, and the overall use is convenient.

[0057] S6: The external control terminal displays and analyzes the data, fits the data point cloud into a three-dimensional model through reverse engineering, and counts the parameters to form a summary table.
