Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering, and particularly relates to a device for detecting the displacement of a slope in geotechnical engineering. Background Art

[0002] Geotechnical engineering mainly refers to some underground construction projects such as slopes, foundation pits and tunnels. According to different types of projects, the equipment and tools used are also different. When constructing a slope, since the slope is mainly a slope with a certain gradient, subsequent displacement may occur in the slope area due to external factors, thus causing potential safety hazards, and it is necessary to detect through a device for detecting the displacement of a slope in geotechnical engineering.

[0003] The existing Chinese patent with the publication number: CN114111666A discloses a device for detecting the displacement of a slope in geotechnical engineering, including a supporting circular plate, a fixed column body, and a displacement detection component. The center of the lower surface of the supporting circular plate is fixedly installed with a positioning support column. The positioning support column includes a hollow column body with a conical bottom end, a positioning hole, a limiting groove, a collar, a return spring, a support platform, a positioning groove, a first spherical ball, a connecting rod, a second spherical ball, a positioning insertion rod, and a connecting frame. A collar is sleeved on the outer circle of the hollow column body, and the collar is screwed with the threaded section of the hollow column body.

[0004] Since the hollow column body serving as a support in the above-mentioned prior art is hollow and partially provided with limiting grooves, the support strength of the hollow part of the hollow column body serving as a support and the wall part of the limiting groove will be reduced. When the displacement of the geotechnical slope occurs after being connected to the geotechnical slope, the hollow column body is easily squeezed and deformed or even broken under the displacement force of the geotechnical slope, and the components inside the hollow column body may be damaged. Summary of the Utility Model

[0005] The utility model provides a device for detecting the displacement of a slope in geotechnical engineering, and the bending resistance of the hollow column body is increased as a whole by arranging a reinforcing disc and a bending resistance component.

[0006] The utility model provides a device for detecting the displacement of a slope in geotechnical engineering, including a hollow column body, and further including: a bending resistance component and a reinforcing disc. The bending resistance component is connected to the hollow part of the hollow column body, and the bending resistance component is used to increase the bending resistance of the supporting part of the hollow column body. The outer diameter of the reinforcing disc matches the inner diameter of the hollow column body and is placed in the upper opening of the hollow column body, and the reinforcing disc is used to reinforce the upper opening of the hollow column body.

[0007] Preferably, a plurality of blind holes are axially formed in the wall thickness part at the upper end of the hollow column body, the axial length of the blind holes is longer than the hollow part of the hollow column body, and the bending resistance component includes a plurality of bending resistance rods, and the plurality of bending resistance rods are inserted and connected to the blind holes in a one-to-one correspondence.

[0008] Preferably, the multiple blind holes are evenly distributed and avoid the position of the upper limit groove on the hollow cylinder.

[0009] Preferably, the anchor tip at the lower conical part of the hollow cylinder is a solid body, and the bottom of the blind hole extends into the solid body.

[0010] Preferably, an internal thread groove is provided in the blind hole, and a hollow threaded rod for threaded connection with the internal thread groove is sleeved outside the bending resistance rod, and the bending resistance rod is fixedly connected to the threaded rod.

[0011] Preferably, it further includes a blind plate fixedly connected to the reinforcement plate. The blind plate is fixedly connected to the upper end of the hollow cylinder, and the reinforcement plate is fixedly connected to the middle of the blind plate.

[0012] Preferably, a flange extends downward along the outer edge of the lower end surface of the blind plate. The flange is annular, and the inner wall size of the flange matches the outer diameter size of the hollow cylinder. The flange is used to reinforce the connection between the hollow cylinder and the blind plate.

[0013] Preferably, the threaded rod is made of cast iron.

[0014] Preferably, the bending resistance rod is rod-shaped and made of cast iron.

[0015] Preferably, the bending resistance rod is a rod-shaped steel bar.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: The reinforcement plate provided can reinforce the upper opening part of the hollow cylinder near the limit groove. The bending resistance member can reinforce the inner wall of the hollow part of the hollow cylinder. The reinforcement plate and the bending resistance member as a whole increase the bending strength of the hollow cylinder.

[0023] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0024] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solutions of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0025] refer to Figure 1 The utility model provides a geotechnical engineering slope displacement detection device, including a hollow cylinder 1, and also includes: an anti-bending part 2 and a reinforcement plate 3. The anti-bending part 2 is connected to the hollow part of the hollow cylinder 1, and the anti-bending part 2 is used to increase the bending strength of the supporting part of the hollow cylinder 1. The outer diameter of the reinforcement plate 3 matches the inner diameter of the hollow cylinder 1 and is placed in the upper opening of the hollow cylinder 1. The reinforcement plate 3 is used to reinforce the upper opening of the hollow cylinder 1.

[0026] In the above embodiments, the reinforcement plate 3 is provided to reinforce the upper opening portion of the hollow column 1 near the limit groove 12, and the anti-bending part 2 is provided to reinforce the inner wall of the hollow part of the hollow column 1. The reinforcement plate 3 and the anti-bending part 2 increase the bending strength of the hollow column 1 as a whole. When the rock slope moves during the detection period, the hollow column 1 reduces the deformation caused by the high-strength extrusion pressure of the slope under the resistance of the reinforcement plate 3 and the anti-bending part 2, and also prevents the hollow column 1 from breaking, avoiding damage to the hollow internal components.

[0027] Further, referring to the figure, a plurality of blind holes 11 are axially opened in the thick wall portion of the upper end of the hollow cylinder 1, and the axial length of the blind hole 11 is longer than the hollow part of the hollow cylinder 1. The anti-bending part 2 includes a plurality of anti-bending rods 21, and the plurality of anti-bending rods 21 are inserted and connected in the blind holes 11 one by one. The conical anchor tip at the lower part of the hollow cylinder 1 is a solid body, and the bottom of the blind hole 11 extends into the solid body.

[0028] In the above embodiments, through the provided blind holes 11, the entire inlaid connection between each bending resistance rod 21 and the inner wall of the hollow column 1 can be achieved. The bending resistance rod 21 is in contact with the inner wall of the blind hole 11, increasing the contact area and enhancing the firmness. By setting the axial length of the blind hole 11 to be longer than the hollow part of the hollow column 1, and the bottom of the blind hole 11 extending into the solid body, when the hollow column 1 is subjected to the squeezing force of the slope, the reinforcement plate 3 and the anchor tip of the hollow column 1 respectively provide upper and lower end limiting and supporting forces to each bending resistance rod 21, thereby overall enhancing the firmness of the hollow column 1.

[0029] Further, referring to Figure 3 , considering that the position where the blind holes 11 are set may interfere with the position of the limiting grooves 12 of the hollow column 1, a plurality of blind holes 11 are evenly distributed and all avoid the positions of the limiting grooves 12 on the hollow column 1.

[0030] In the above embodiments, specifically, the number of the plurality of blind holes 11 is four, and it is not limited to four. The more the number, the stronger the impedance force and the better the bending resistance strength. Considering the cost and the distribution method, four are optimally selected.

[0031] Further, referring to Figure 4 , considering that it is not easy to install the bending resistance rod 21 into the blind hole 11, and directly choosing welding fixation is not easy for later maintenance and replacement. Therefore, an internal thread groove is provided in the blind hole 11, and a hollow threaded rod 4 for threaded connection with the internal thread groove is sleeved outside the bending resistance rod 21, and the bending resistance rod 21 is fixedly connected with the threaded rod 4.

[0032] In the above embodiments, through the provided threaded rod 4, the bending resistance rod 21 can be connected to the hollow column 1 in a detachable spiral manner. At the same time, when the hollow column 1 is subjected to a squeezing force, the threaded rod 4 can also provide partial impedance force, increasing the bending resistance strength of the overall structure.

[0033] Further, referring to Figure 2 and Figure 4 , it further includes a blind plate 5 for fixedly connecting with the reinforcement plate 3. The blind plate 5 is fixedly connected to the upper end of the hollow column 1, and the reinforcement plate 3 is fixedly connected to the middle of the blind plate 5.

[0034] In the above embodiments, the provided blind plate 5 is fixedly connected with the reinforcement plate 3, and the blind plate 5 is fixedly connected with the hollow column 1 to limit the position of the reinforcement plate 3.

[0035] Further, referring to Figure 2 and Figure 4 , a flange 51 extends downward along the outer edge of the lower end face of the blind plate 5. The flange 51 is annular, and the inner wall size of the flange 51 matches the outer diameter size of the hollow column 1. The flange 51 is used to reinforce the connection between the hollow column 1 and the blind plate 5.

[0036] In the above embodiments, an annular groove is formed between the provided flange 51 and the reinforcement plate 3, and the upper opening of the hollow cylinder 1 extends into the groove, increasing the contact surfaces between the inner and outer walls of the hollow cylinder 1 and the flange 51 and the reinforcement plate 3, and enhancing the firmness after welding.

[0037] Further, referring to Figure 3 and Figure 4 , the threaded rod 4 is made of cast iron, and the bending-resistant rod 21 is a rod-shaped one made of cast iron.

[0038] In the above embodiments, by being limited to cast iron material, the cost is relatively low and the hardness is relatively high, and it can withstand a certain extrusion force.

[0039] Further, referring to Figure 3 , considering that cast iron has relatively high hardness but poor toughness and may break when subjected to high-strength extrusion force, it is therefore preferred that the bending-resistant rod 21 is a rod-shaped steel bar.

[0040] In the above embodiments, the steel bar has high bending resistance and also has impedance toughness, which can avoid fracture.

[0041] Only several specific embodiments of the present utility model are disclosed above. However, the embodiments of the present utility model are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present utility model.
