Problems solved by technology

Once the road slope is unstable, it will not only seriously affect the safety of the project, but also seriously threaten the surrounding environment and even the safety of personal and property, bringing bad social impact
[0004] However, the existing technology is insufficient for the stability of the slope, and the anchor rods used cannot achieve high-strength support. The stability of the slope protection layer is weak, and the protection layer is all hardened, which cannot achieve a green and low-carbon environment. Therefore, facing the urgent needs of the current expressway construction in Guangxi, it is urgent to develop new technologies to realize multi-point restraint anchor cables and improve the stability of high road slopes

Embodiment 1

[0038] An improved lattice anchor composite slope reinforcement structure, including a slope surface and a reinforcement structure arranged on the slope surface, the reinforcement structure includes a fixed wall 2 and an anchor net;

[0039] The fixed wall 2 includes a number of fixed columns 21 and a number of beams 22; the fixed columns 21 are fixedly installed at the bottom of the slope at equal intervals; the top surface of the fixed column 21 is provided with installation grooves; the two ends of the beams 22 are fixedly installed in two adjacent installation grooves;

[0040] The anchoring net includes a lattice 3 and an anchor rod 4; the lattice 3 is fixedly connected to one side of the beam 22; the lattice 3 is fixedly connected to the slope through the anchor rod 4.

[0041] In a further optimization scheme, the anchor rod 4 includes a horizontal fastening unit 41, several oblique fastening units 42, anchor pipes 43 and fastening units 44; the horizontal fastening unit...

Embodiment 2

[0073] The difference between this embodiment and the above is that the bottom end of the inclined hole is inclined towards the pressure plate 441, and the guide cylinder 7 is screwed in the inclined hole; one end of the guide cylinder 7 is flush with the outer surface of the anchor pipe 43, and is arranged on the anchor pipe. The other end of the 43 inner cavity is provided with a relief groove; the relief groove can ensure that the universal tube is smoothly introduced into the guide cylinder 7, facilitates the bending of the universal joint 423, realizes the rapid introduction of the universal tube, and improves work efficiency.

Embodiment 3

[0075] The difference between this embodiment and the above-mentioned embodiment is that the top surface of the beam 22 is provided with a rotating groove 1; the two ends of the rotating groove 1 are rotatably connected with a rotating shaft 8, and the rotating shaft 8 passes through the bushing 9 and a plurality of screen plates 32 close to the beam 22. One end is rotationally connected; any one end of the rotating shaft 8 is respectively rotationally connected to one end of two adjacent beams 22 , and the two adjacent rotating shafts 8 are not connected to each other. This embodiment realizes that the lattice structure 3 can be laid on slopes of different angles, which expands the adaptability of the environment; and realizes the separation of the lattice structure 3 and the beam 22, which is conducive to modular production and improves the transportation and laying efficiency. Convenience.

Description

technical field [0001] The invention relates to the field of infrastructure construction, in particular to an improved lattice-bolt composite slope reinforcement structure and a construction method. Background technique [0002] Guangxi is located in the southwestern part of the motherland, at latitude 20°54′~26°23′ north, longitude 104°29′~112°04′ east. Accounting for 71% of the total area, most of the mountains are strongly cut, with great differences in elevation, most of the slopes are greater than 30°, and the geological and landform environmental conditions are complex. Located in the subtropical monsoon climate zone, affected by the combined effect of ocean and plateau climate, high temperature and rainy weather are conducive to the weathering of rock and soil, resulting in various geological disasters. Therefore, Guangxi is a region with fragile geological environment and frequent geological disasters, and is listed as one of the seven provinces with frequent geolog...
