Damage to the highway can significantly affect emergency rescue efforts. Therefore, it is necessary to drill into the top of the highway subgrade slope to detect the pore water pressure and permeability inside the slope.

[0003] Therefore, it is necessary to provide a rapid detection device for the collapse of highway subgrade slopes caused by burst floods, in order to solve the problems mentioned in the background art. Summary of the Invention

[0005] Furthermore, the detection device includes a column box, a second motor, and a detection rod. The column box is rotatably assembled in the drill barrel, and a second gear is fixed to its left end. The second motor is fixed to the left side of the drill barrel, and a third gear that meshes with the second gear is fixed to the output end of the second motor. Detection rods with a cross mechanism are distributed on the outside of the column box, and the detection rods include detection modules that correspond to the detection holes.

[0006] Furthermore, the detection module includes a detection shell, a sealing plate, a main shaft, an auxiliary shaft, and a permeation belt. The sealing plate is respectively mounted on the left and right ends of the detection shell. The outer wall of the detection shell is provided with a detection port, and an auxiliary shaft with a trapezoidal distribution is provided between the left and right ends of the sealing plate. The permeation belt is sleeved on the auxiliary shaft, and an elastic monitoring frame is also installed on the outer wall of the sealing plate. A retaining seat is installed on the elastic monitoring frame. The sealing plate is also provided with a sliding joint for axial drilling cylinder axis. The left and right ends of the main shaft are respectively installed on the retaining seat through the sliding joint and are used to support the permeation belt.

[0007] Furthermore, a motor for driving and controlling the rotation of the main shaft is installed on one end of the fixed seat.

[0008] Furthermore, the probe port is provided with an inclined scraper.

[0009] Furthermore, the space enclosed by the permeation zone is provided with a triangular support plate with an opening facing the detection port. Both ends of the support plate are fixedly connected to two side sealing plates. A water-guiding cotton strip is filled between the triangular support plate and the permeation zone. The inner side of the sealing plate is provided with a groove. A pressure plate is provided in the groove at the left end, and a water-permeable baffle is provided in the groove at the right end.

[0013] Compared with the prior art, the present invention provides a rapid detection device for the collapse of highway subgrade slopes caused by floods, which has the following advantages:

[0014] This invention utilizes artificially synthesized permeable strips. These strips are prepared within a safe range based on the pore water pressure and permeability conditions of the slope. The maximum permeable strip is designed to accommodate the pore water pressure and permeability within the slope under safe conditions. This serves as a comparison with actual measured pore water pressure and permeability, allowing for rapid assessment of the slope's pore water pressure and permeability. An elastic monitoring frame allows for adjustment of the permeable strip's tension, ensuring a tight seal around the detection port. This creates a sealing tension when the detection port aligns with the detection hole, simulating the pore water resistance within the slope. As pore water flows into the permeable strip, it provides an initial pore water pressure condition suitable for slope safety, facilitating more effective and direct detection of the permeation rate. As the pressure on the permeable strip increases, the elastic monitoring frame monitors the pore water pressure, its distribution, and its area in real time. This allows for rapid assessment of the pore water pressure within the slope, determining whether the permeability exceeds the slope's internal seepage resistance and promptly identifying potential slope collapse.

Detailed Implementation

[0027] Reference Figures 1-11This invention provides a technical solution: a rapid detection device for detecting the collapse of highway subgrade slopes caused by floods, comprising a handle 1 and a detection device 6. The handle 1 is equipped with a gear 2 and a gear ring 3 that are mutually driven. The gear 2 is driven and controlled by a motor 5. A drilling cylinder 4 is mounted on the gear ring 3, and the drilling cylinder 4 has detection holes 41 with a cross-shaped detection direction. The detection device 6 is located inside the drilling cylinder 4 and detects the area facing the detection holes 41. By holding the handle, the drilling cylinder can be quickly picked up, placed, and positioned. With the start of the motor, the drilling cylinder can be driven to drill the slope. After drilling, the drilling cylinder can be slowly rotated by the motor to adjust the detection direction of the detection holes towards the pore water pressure and permeability conditions within the slope to be detected.

[0028] The detection device 6 includes a column box 61, a second motor 63, and a detection rod 7. The column box 61 is rotatably mounted in the drill barrel 4, and a second gear 62 is fixed to its left end. The second motor 63 is fixed to the left side of the drill barrel 4, and a third gear 64 that meshes with the second gear 62 is fixed to the output end of the second motor 63. The detection rod 7 with a cross mechanism is distributed on the outside of the column box 61, and the detection rod 7 includes a detection module 8 that corresponds to the detection hole 41. The detection module 8 includes a detection shell 81, a sealing plate 82, a main shaft 85, an auxiliary shaft 86, and a penetration strip 87. The left and right ends of the detection shell 81 are respectively equipped with The sealing plate 82 has a detection port 812 on the outer wall of the detection shell 81, and an auxiliary shaft 86 arranged in a trapezoidal shape between the left and right ends of the sealing plate 82. The permeation tape 87 is sleeved on the auxiliary shaft 86, and an elastic monitoring frame 83 is also installed on the outer wall of the sealing plate 82. A retaining seat 84 is installed on the elastic monitoring frame 83. The sealing plate 82 also has a sliding joint 821 axially aligned with the axis of the drilling cylinder 4. The left and right ends of the main shaft 85 pass through the sliding joint 821 and are installed on the retaining seat 84, and are used to support the permeation tape 87. A motor 810 for driving and controlling the rotation of the main shaft 85 is installed on one end of the retaining seat 84.

[0029] The permeable strip is artificially synthesized. In other words, based on the safe range of pore water pressure and permeability of the slope, a permeable strip is prepared to meet the maximum value of pore water pressure and permeability that can be contained within the slope under safe conditions. This permeable strip is used as a comparison value with the actual detected pore water pressure and permeability of the slope, so as to quickly determine and obtain the pore water pressure and permeability of the slope.

[0030] The size of the detection port is smaller than that of the detection hole, so that the tension of the permeable strip can be adjusted by the elastic monitoring frame. This ensures that the permeable strip seals and fits the detection port, creating a certain sealing tension when the detection port and the detection hole are aligned. This simulates the resistance of pore water in the slope. In other words, when pore water flows into the permeable strip, it provides an initial safe pore water pressure condition for the slope, facilitating the detection of its permeation rate. As the pressure on the permeable strip increases, the elastic monitoring frame can monitor the pore water pressure status, distribution, and distribution area in real time.

[0031] The detection port 812 is equipped with an inclined scraper blade. With the control of the motor, it is beneficial to change the local permeable zone after the local permeable zone is used to detect the pore water pressure and permeability. The scraper blade can also remove dirt from the surface in time during the rotation.

[0032] The space enclosed by the permeation zone 87 includes a triangular support plate 814 with its opening facing the detection port 812. Both ends of the triangular support plate 814 are fixedly connected to end sealing plates 82. A water-guiding cotton strip 88 fills the space between the triangular support plate 814 and the permeation zone 87. The inner side of the end sealing plate 82 has a groove; a pressure plate 89 is located in the groove on the left, and a water-permeable baffle 815 is located in the groove on the right. A second sealing plate 811, connected to the right end sealing plate 82 via a metering pipe 816, is also installed on the right side of the first right sealing plate 82. A telescopic rod 71 is installed on the left side of the first left sealing plate 82, and a telescopic mechanism is installed within the rod 71. The output end of the telescopic rod 711 is connected to the connecting rod 712. The connecting rod 712 passes through the pressure plate and the water-guiding strip 88 and extends into the cavity 721 in the box rod 72. The box rod 72 is installed on the right sealing plate 811, and the connecting rod is fixedly assembled with the pressure plate and slidably assembled with the water-guiding strip 88. That is to say, the water that has seeped in is attracted in time by the water-guiding strip so that the pore water in the slope can continue to seep in. Then, by adjusting the connecting rod through the telescopic rod 711, the pressure plate is driven to squeeze the water-guiding strip, so that the seeped water can be measured by the metering pipe and flow into the sealing plate 88 in time.

[0033] Among them, an inner arc plate 813 that fits against the inner wall of the drilling tube is also connected between adjacent detection shells 81 to form a sealing structure.

[0034] The column box 61 has a main cavity 611 on its axial part and a sub-cavity 612 on its periphery that communicates with the column cavity 611. The sub-cavity 612 is connected to the sealing plate 811. The left end of the main cavity 611 is provided with a telescopic rod 65. A piston 66 is installed at the output end of the telescopic rod 65. The drill bit of the drilling tube is also provided with a through hole 613 so that water in the sealing plate 811 can be introduced into the main cavity. Then, the piston is pushed by the telescopic rod to discharge the water in time for the next slope detection.

[0035] The surface of the permeation tape 87 is covered with a water-permeable membrane to improve the smoothness of the permeation tape and facilitate the cleaning of the permeation tape by the scraper.

[0036] In practice, based on the slope texture and structure to be tested, a permeable zone is prepared that meets the maximum requirements for accommodating the internal pore water pressure and permeability under safe conditions. After completion, the zone is assembled, and the drilling barrel is operated by hand to drill into the slope to be tested. The orientation of the probe hole is then adjusted, and the probe port is aligned with the probe hole by adjusting the motor. After a certain period of time, the probe port is repositioned by adjusting the motor again, and then the probe is removed and the measured data is collected. This allows for a quick assessment of the pore water pressure and permeability within the slope.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
