Description

Technical Field

[0001] This utility model relates to the technical field of geotechnical engineering protection, specifically to geotechnical protection structures for road slopes. Background Technology

[0002] Civil engineering encompasses all types of engineering projects, including those above ground, underground, and underwater projects. The portion of civil engineering involving rock, soil, underground, and underwater elements is termed geotechnical engineering. For slopes in geotechnical engineering, common failure types are collapse and landslide. A landslide is the process and phenomenon of rock and soil masses sliding downwards along a pre-existing geological interface or a newly formed shear failure surface. Among slope failures, landslides are the most common and severe type.

[0003] Existing slope protection methods generally use anchoring structures to anchor the main protection structure to the slope. However, since slope angles vary, it is difficult to adjust the protection angle using a single vertical steel rod according to the slope angle, which in turn affects the effectiveness of slope protection at different angles. Summary of the Invention

[0004] The purpose of this invention is to provide a soil and rock protection structure for road slopes to solve the aforementioned defects caused by the prior art.

[0005] The roadside slope rock and soil protection structure includes a steel structural pole, a metal mesh, and side support arms. A nut is connected through one side of the steel structural pole, and protective mechanisms are installed on both sides of the steel structural pole. The protective mechanisms adjust the angle of the steel structural pole according to the angle of the mountain, thereby facilitating the protection of rock and soil at different angles and reducing the possibility of falling rocks. A support structure is installed on one side of the steel structural pole to support one side of the steel structural pole, thereby improving the positioning and protective stability of the steel structural pole and the metal mesh on both sides.

[0006] Preferably, the protective mechanism includes a metal mesh, grooved rods, fastening holes, shaft positioning seats, positioning grooves, and fasteners. Grooved rods are symmetrically arranged on the outer side of the metal mesh. The fastening holes are equally spaced on the outer side of the grooved rods. Positioning grooves are provided on both sides of the steel structure rod. The bottom end of the steel structure rod is connected to a shaft positioning seat. Multiple sets of fasteners are equally spaced on the outer side of the steel structure rod.

[0007] Preferably, the metal mesh is connected to the outside of the positioning groove by symmetrically arranged grooved rods.

[0008] Preferably, the steel structure rod is connected to two sets of anchor rods via a shaft positioning seat at its bottom end.

[0009] Preferably, the support structure includes an anchor rod, a side support arm, a groove, a bearing housing, and anchor holes. The anchor rod is threaded to the outside of the shaft positioning seat. A side support arm is provided on one side of the shaft positioning seat. An anchor holes are symmetrically opened at the bottom end of the side support arm. A bearing housing is provided on one side of the side support arm. The bearing housing is located on one side of the steel structure rod. A groove is opened on the outside of the steel structure rod.

[0010] Preferably, the side support arm is connected to the outside of the slide groove via a bearing seat at the top.

[0011] Preferably, the grooved rod is connected to a fastener through equally spaced fastening holes.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. A shaft positioning seat is installed at the bottom of the steel structure pole. The shaft positioning seat drives the steel structure pole to rotate, thereby adjusting the angle of the steel structure pole. The positioning seat is fixed to the steel structure pole by a positioning hole set in the outer end of the shaft positioning seat. The horizontal or vertical angle of the protective net is adjusted by rotating the shaft positioning seat, and the fit angle between the protective net and the slope is flexibly adjusted to adapt to the complex terrain of the adjacent edge.

[0014] 2. During use, the side support arm on one side is used to connect the steel structure pole to one side. The connection height and support angle of the side support arm are then adjusted synchronously according to the angle of the steel structure pole, thus ensuring the stability of the steel structure pole during the protection process.

Multiple sets of fasteners 14 are equally spaced on the outer side of the steel structure rod 1. The grooved rod 4 and the metal mesh 3 are positioned at multiple points by the equally spaced fasteners 14.

[0025] In this embodiment, the metal mesh 3 is connected to the outside of the positioning groove 11 by symmetrically arranged grooved rods 4. The grooved rods 4 are used to position the two sides of the metal mesh 3, thereby improving the convenience of installation and positioning of the metal mesh 3.

[0026] In this embodiment, the steel structure rod 1 is connected to two sets of anchor rods 8 through the shaft positioning seat 7 set at the bottom. The shaft positioning seat 7 is positioned by the symmetrically arranged anchor rods 8 to ensure the stability of the shaft positioning seat 7 installation.

[0027] The support structure 9 includes an anchor rod 8, a side support arm 10, a sliding groove 12, a bearing seat 13, and an anchor hole 15.

[0030] In practical applications, the soil and rock protection structure for this type of road slope includes the following tasks:

[0031] Step 1: During use, first install the shaft positioning seat 7 on one side of the protective soil and rock layer. Then, vertically insert the anchor rod 8 into the bottom of the shaft positioning seat 7. The anchor rod 8 is used to position the shaft positioning seat 7 and the underground rock layer. Then, according to the angle of the soil and rock layer, the angle of the steel structure rod 1 is adjusted by rotating it on the outside of the shaft positioning seat 7. Finally, the screw and nut 2 are used to position the shaft positioning seat 7 and the outside of the steel structure rod 1 to prevent the steel structure rod 1 from loosening.

[0032] Step 2: Then connect the protruding part of the bearing seat 13 on one side of the side support arm 10 to the slide groove 12.
