Embodiment 1

[0040] Example 1, such as Figure 1-10 As shown, the slope support mechanism includes a support frame 1 and an anchor rod 2. The support frame 1 is composed of an inclined part 10 and a horizontal part 11. Concrete frame, the upper end of the inclined part 10 is horizontally provided with an upper extension end, and the upper extension end is placed on the top of the slope body 5, and the lower end of the inclined part 10 is horizontally provided with a lower extension end, and the lower extension end is placed at the bottom of the slope body 5. The extension end and the lower extension end form a horizontal part 11, and blind holes 50 inclined downward are evenly opened on the outer surface of the slope body 5, and the lower end of the anchor rod 2 is anchored in the blind hole 50 of the slope body 5, and the upper end is embedded in the support frame In the concrete protrusion 12 at the center of each of the four adjacent grids 6 of 1, elastic protective sleeves 20 are evenl...

Embodiment 2

[0051] Embodiment 2, the difference with embodiment 1, such as Figure 11 As shown, the inner surface of the support frame 1 is bonded with a metal mesh 13, and the metal mesh 13 is close to the outer surface of the slope body 5; the advantage is that the metal mesh 13 prevents the exposed debris in the grid 6 of the support frame 1 The sliding of rocks and easy-to-fall rock formations plays a better role in reinforcing the slope 5.

[0052] The construction method of described slope support mechanism, its steps comprise:

[0053] A, uniformly drill a plurality of blind holes 50 inclined downward on the outer surface of the slope body 5, and each blind hole 50 extends into the slope body 5;

[0054] B, evenly set a plurality of openings on the anchor rod 2 and place elastic protective sleeves 20 on the side of the anchor rod 2;

[0055] C, install the lower end of the anchor rod 2 into the blind hole 50, and fix it by grouting;

[0056] D, the two ends of the reinforcement ...

Abstract

The invention relates to a slope supporting mechanism and a construction method thereof. The slope supporting mechanism comprises a supporting frame and anchor rods. Blind holes are uniformly formed in the outer surface of a slope body, the lower ends of the anchor rods are anchored in the blind holes of the slope body, and the upper ends of the anchor rods are embedded in concrete bulges at the centers of every four adjacent grids of the supporting frame, elastic protective sleeves are arranged on the side surfaces of the anchor rods, a fixed piece is arranged in the supporting frame, the fixed piece comprises two strip-shaped straight pipe bodies and a U-shaped strip-shaped pipe body, a reinforcing belt penetrates through the fixed piece, the two ends of the reinforcing belt penetrate through the fixed piece and extend out of the lower ends of the two belt-shaped straight pipe bodies respectively, guide rods are fixed to the upper surfaces of the two ends of the reinforcing belt respectively, and the reinforcing belt and the guide rods which are fixed together are anchored in the blind holes in the slope body, so that the problems that the anchor rods are not prone to being coaxial with and colliding with the holes during installation, anchoring of the anchor rods is not firm, and a retaining wall or a frame is prone to being disengaged from the slope body are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a slope support mechanism and a construction method thereof. Background technique [0002] Slope refers to the slope with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. The instability of the slope seriously endangers personal safety and national property loss. In order to ensure the safety of construction and traffic, slope reinforcement and governance It has become an infrastructure of our country. [0003] To strengthen the slope reinforcement treatment, frame prestressed anchor rods are generally used to reinforce the structure. The prestressed anchors on the slope make the anchor rods play the role of reinforcing the landslide body and gravel, preventing the slope body from moving downward and collapsing. It is a rigid material. It is easy to collide and wear in the hole during installation, and it is not easy to be c...
