Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering remediation technology, and in particular to a geotechnical engineering slope anchoring support structure. Background Technology

[0002] In scenarios such as road cuts, foundation pits, natural slopes, and mine slopes, in order to prevent geological disasters such as landslides and collapses, it is necessary to set up anchored support structures on geotechnical engineering slopes. By drilling holes into the slope's soil and rock mass and inserting high-strength anchor rods, the axial tensile force is used to reinforce the unstable soil and rock mass, tightly connecting the potential sliding body with the stable bedrock, thereby significantly improving the overall stability and anti-sliding capacity of the slope.

[0003] In traditional geotechnical engineering slope anchoring structures, rock and soil are fixed by anchor rods and the surface of rock and soil is covered by ropes. However, there is a lack of a stable and efficient connection structure between the ropes and anchor rods. The surface of the rock and soil slope lacks effective integration with the internal structure of the rock and soil, and the support and protection of the slope surface is not stable enough. Utility Model Content

[0004] This utility model provides a slope anchoring support structure for geotechnical engineering to solve the problem that traditional slope anchoring structures in geotechnical engineering fix the soil and rock by anchoring rods and covering the soil and rock surface with ropes. However, these structures lack a stable and efficient connection structure between the ropes and anchoring rods, resulting in an ineffective combination between the soil and rock slope surface and the internal structure of the soil and rock, and insufficient support and protection for the slope surface.

[0005] This utility model provides a slope anchoring support structure for geotechnical engineering, specifically including: anchor bolts, anchor caps, and support ropes. The anchor bolts are distributed in the middle of the mesh formed by the cross-arranged support ropes. The anchor bolts longitudinally penetrate the anchor caps and are inserted into the soil layer. The top of the anchor bolts is spirally connected to a bolt cap, which is located on the top of the anchor cap. Four sets of guide rods are distributed on the outer edge of the anchor cap. Each set of guide rods consists of two side guide rods, which are perpendicular to the side wall of the anchor cap. The guide rod sets are connected to sliding connecting rods. The outer end of the sliding connecting rods is hinged to an upper cover plate and a lower cover plate. The upper cover plate and the lower cover plate are connected by locking bolts. The support ropes are held between the upper cover plate and the lower cover plate.

[0006] Furthermore, the anchoring cover has a through-hole in the center, the anchoring screw is slidably connected to the through-hole, and the upper edge of the through-hole is machined with an arc-shaped flange.

[0007] Furthermore, the lower half of the screw cap is provided with a spherical top block with a hemispherical structure, and a cap handle is fixedly connected to the outside of the screw cap.

[0008] Furthermore, the inner surface of the side guide rod is provided with a guide rod protrusion, and a sliding connecting rod is slidably connected between the two side guide rods. A connecting rod groove is provided on the upper and lower surfaces of the sliding connecting rod, and the connecting rod groove is slidably connected to the guide rod protrusion.

[0009] Furthermore, the sliding connecting rod has four fixed-distance insertion holes running longitudinally through it, and the side guide rod has an adjustable-distance insertion hole running longitudinally through it. The adjustable-distance insertion hole and the fixed-distance insertion hole are connected by bolts.

[0010] Furthermore, the lower surface of the upper cover plate is provided with an upper rope placement groove, and the upper surface of the lower cover plate is provided with a lower rope placement groove, the upper rope placement groove and the lower rope placement groove being perpendicular to each other.

[0011] Furthermore, the lower cover plate has a through spiral hole, and a locking bolt is spirally connected to the spiral hole. The locking bolt is longitudinally connected to the upper cover plate.

[0012] This utility model provides a slope anchoring support structure for geotechnical engineering, which has the following beneficial effects:

[0013] In the geotechnical engineering slope anchoring support structure of this utility model, an anchoring cap and a support rope connection structure are provided. By fixing the outer end of the anchoring bolt inserted into the soil and rock to the support rope laid and covering the outer surface of the slope, the support rope is more firmly fixed to the slope, so that the support rope can more firmly fix the rocks and soil layers on the slope surface, and prevent the protective net composed of support ropes from falling off due to landslides, falling rocks, etc.

[0014] In addition, the connection structure between the anchor cap and the support rope can adjust the connection spacing. By sliding the connecting rod and the side guide rod, and with the upper and lower cover plates clamping the protection net nodes, the spacing between the cross nodes of the support rope and the anchor cap can be adjusted. This allows for tolerance, making the construction of the slope protection structure more flexible, and it can also be used in combination with protection nets of different sizes.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1 to 6 : This utility model proposes a slope anchoring support structure for geotechnical engineering, comprising: anchor bolts 1, anchor caps 2, and support ropes 9. The anchor bolts 1 are distributed in the middle of a mesh formed by the cross-arranged support ropes 9. The anchor bolts 1 longitudinally penetrate the anchor caps 2 and are inserted into the soil layer. A screw cap 3 is spirally connected to the top of the anchor bolts 1, located at the top of the anchor caps 2. Four sets of guide rods are distributed along the outer edge of the anchor caps 2. Each set of guide rods consists of two side guide rods 4, which are perpendicular to the sidewall of the anchor caps 2. The guide rod sets are connected to sliding connecting rods 5. An upper cover plate 6 and a lower cover plate 7 are hinged to the outer end of the sliding connecting rod 5. The upper cover plate 6 and the lower cover plate 7 are connected by locking bolts 8. Support ropes 9 are held between the upper cover plate 6 and the lower cover plate 7. During slope support construction, the anchor bolts 1 are inserted into the soil slope, and... Anchor cap 2 is fitted onto the outer end of anchor bolt 1, allowing the anchor bolt 1 to slide into the cap through 201. Bolt cap 3 is screwed into the end of anchor bolt 1, ensuring the spherical top block 301 fits tightly against the arc edge 202 of the through 202, thus securing and positioning the anchor cap 2 to prevent loosening. Then, a protective net composed of support ropes 9 is laid on the slope surface to cover the rocks and soil. The upper cover plate 6 and lower cover plate 7 are rotated and unfolded, and the sliding connecting rod 5 is moved to position the upper cover plate 6 and lower cover plate 7 at the node of the protective net. The vertically intersecting support ropes 9 at the node are placed through the two vertical placement slots in the upper cover plate 6 and lower cover plate 7. Finally, the upper cover plate 6 and lower cover plate 7 are secured and locked with locking bolts 8, achieving a firm connection between the support ropes 9 and the anchor bolt 1, thus improving the coverage of the slope surface by the support ropes 9.

[0021] In this embodiment, the anchoring cover 2 has a through-hole 201 at its center, the anchoring screw 1 is slidably connected to the through-hole 201, the upper edge of the through-hole 201 is machined with an arc-shaped arc edge 202, the lower half of the screw cap 3 is provided with a hemispherical spherical top block 301, and a screw cap handle 302 is fixedly connected to the outside of the screw cap 3; the anchoring cover 2 is fitted onto the outer end of the anchoring screw 1, so that the anchoring screw 1 is slidably connected to the through-hole 201, and the screw cap 3 is screwed into the end of the anchoring screw 1, so that... The spherical top block 301 fits tightly against the through-hole arc edge 202, providing a stable and secure clamping position for the anchoring cover 2, preventing it from loosening. The spherical top block 301 with its spherical structure can also adjust the angle, allowing for a certain angular deviation between the spherical top block 301 and the anchoring cover 2. This ensures that the screw cap 3 maintains a tight and limited position on the anchoring cover 2. The screw cap handle 302 improves the ease of rotation of the screw cap 3, reduces reliance on external tools, and is suitable for slope protection that requires frequent adjustments and modifications.

[0022] In this embodiment, the inner surface of the side guide rod 4 is provided with a guide rod protrusion 401, and a sliding connecting rod 5 is slidably connected between the two side guide rods 4. A connecting rod groove 501 is provided on the upper and lower surfaces of the sliding connecting rod 5, and the connecting rod groove 501 is slidably connected to the guide rod protrusion 401. The sliding connecting rod 5 has four fixed-distance insertion holes 502 extending longitudinally, and the side guide rod 4 has an adjustable-distance insertion hole 402 extending longitudinally. The adjustable-distance insertion hole 402 is connected to the fixed-distance insertion hole 502 by bolts. The sliding connecting rod 5 and the side guide rod 4 are slidably connected to provide guidance, and the sliding connecting rod 5 can be adjusted to extend and retract outside the side guide rod 4 by bolts between the adjustable-distance insertion hole 402 and the fixed-distance insertion hole 502, thereby adjusting the position of the upper cover plate 6 and the lower cover plate 7 and accurately locking the nodes of the protective net.

[0023] In Example 2, based on Example 1, an upper rope placement groove 601 is provided on the lower surface of the upper cover plate 6, and a lower rope placement groove 701 is provided on the upper surface of the lower cover plate 7. The upper rope placement groove 601 and the lower rope placement groove 701 are perpendicular to each other. A spiral through hole 702 is provided through the lower cover plate 7, and a locking bolt 8 is spirally connected to the spiral through hole 702. The locking bolt 8 is longitudinally connected to the upper cover plate 6. Through the cooperation between the upper cover plate 6 and the lower cover plate 7, when the upper cover plate 6 and the lower cover plate 7 are fastened together, the locking bolt 8 passes through the upper cover plate 6 and is screwed into the spiral through hole 702, thus firmly locking the upper cover plate 6 and the lower cover plate 7. The setting of the upper rope placement groove 601 and the lower rope placement groove 701 can limit and place the two vertical support ropes 9 respectively, reduce the slippage of the support ropes 9, and improve the connection firmness of the support ropes 9.

[0024] The working principle of this embodiment is as follows: First, the anchor bolt 1 is inserted into the soil slope, and the anchor cap 2 is fitted onto the outer end of the anchor bolt 1, so that the anchor bolt 1 and the cap through-hole 201 are slidably connected. The bolt cap 3 is screwed into the end of the anchor bolt 1, so that the spherical top block 301 and the arc edge 202 of the through-hole are tightly fitted, and the anchor cap 2 is firmly pressed and positioned to prevent it from loosening. Then, a protective net composed of support ropes 9 is laid on the slope surface to cover the rocks and soil layers on the slope surface. The upper cover plate 6 and the lower cover plate 7 are rotated out and moved and slid. Link 5 moves the upper cover plate 6 and the lower cover plate 7 to the node position of the protective net. Through the cooperation of the upper cover plate 6 and the lower cover plate 7, in the snap-fit ​​state of the upper cover plate 6 and the lower cover plate 7, the locking bolt 8 passes through the upper cover plate 6 and screws into the spiral through hole 702, so as to firmly lock the upper cover plate 6 and the lower cover plate 7. Through the setting of the upper rope placement groove 601 and the lower rope placement groove 701, the two vertical support ropes 9 can be limited and placed respectively, reducing the slippage of the support ropes 9, improving the connection firmness of the support ropes 9, and enhancing the resistance to falling rocks and landslides.
