Description

Technical Field

[0002] Geotechnical survey refers to the identification, analysis and evaluation of the geological, environmental characteristics and geotechnical conditions of the construction site according to the requirements of the construction project. Since the depth of the measuring hole may be very large, the traditional detection rod is no longer sufficient to measure the hole depth.

[0003] The Chinese patent with authorization announcement number discloses a hole depth measuring device for rock and soil geological exploration. The device is fixed by a fixing component, a borehole box is placed in the hole, the take-up wheel is rotated, and the borehole box is released by the take-up wheel in conjunction with the tape measure. When the borehole box reaches the ground of the hole, a trigger component is used to trigger a signal, thereby facilitating the location of the borehole box. The extended length of the tape measure can be clearly viewed through the fixed bracket to determine the hole depth.

[0004] However, the device still has some shortcomings: when the aperture is large, the cable on the borehole box remains inclined with respect to the axis of the hole, making its measurement data inaccurate, and a single signal contact switch determines the bottom status of the borehole box, which is prone to misjudgment due to contact with obstacles.

[0028] In this embodiment, the wheel 7 lifts the frame 1 until the baffle 4 is above the ground in the initial state. At this time, the frame is pushed to move to the hole to be measured, and the storage tube 9 is roughly judged to be above the inner side of the hole. Then the hydraulic cylinder 8 is started, and the hydraulic cylinder 8 pulls up the slide 6 to reduce the overall height of the frame 1 to the lowest position. At this time, the baffle 4 is inserted into the hole, and then the two-way module 3 is started. The two-way module 3 drives the movable plates 2 on both sides to move away from each other. When the wheels 7 move away from each other, the baffles 4 on both sides move away from each other synchronously and collide with the inner wall of the hole. With the coordinated cooperation of the four baffles 4, the axis of the storage tube 9 and the center of the hole are on the same axis. At this time, the motor A133 is started. , the motor A133 drives the winding roller 132 to release the cable 14, the detector 15 automatically slides out and inserts into the hole, and the limit block 11 automatically slides down to the lowest position in the storage tube 9 due to its own weight, and then the motor B23 drives the bidirectional screw 20 to rotate, the sliders 21 on both sides move away from each other and the mounting plates 16 are synchronously moved away through the connecting rod 21, until all the tensioning wheels 17 are in conflict with the inner wall of the hole, and the cable 14 is continuously released. The detector 15 is always kept in the center of the hole under the action of the tensioning wheel 17. At this time, even if the hole is tilted downward, the cable between the detector 15 and the limit block 11 always remains coaxial with the axis of the inclined hole, thereby improving the measurement accuracy. When more than half of the pressure sensors B24 detect the pressure signal, it is determined that the detector 15 has reached the bottom, and the wheel distance meter 18 stops counting at this time, and the controller integrates the data measured by the wheel distance meter 18 and displays it on the display.

[0029] Embodiment 2

[0030] like Figure 5As shown, the utility model proposes a hole depth measuring device for rock and soil geological exploration. Compared with the first embodiment, a wheel seat is arranged on the mounting plate 16, a center shaft is arranged on the tensioning wheel 17, the center shaft is rotatably connected with the wheel seat, and a pressure sensor A19 is movably arranged on the mounting plate 16, the pressure sensor A19 is electrically connected with the controller, and the detection end of the pressure sensor A19 is connected with the wheel seat.

[0031] In this embodiment, when the tensioning wheel 17 is spaced apart and contacts the inner wall of the hole, the pressure sensor A19 detects the pressure value. When the pressure value reaches a certain value, it is determined that the detector 15 is coaxial with the center of the hole, thereby avoiding excessive tensioning that causes the tensioning wheel 17 to be inserted into a relatively soft geological layer, thereby causing the detector 15 to be blocked from descending.

[0032] Embodiment 3
