Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] like figure 1 , 2 , shown in 3, 4, and 5, the anti-slide fixing device for the concrete layer of the slope surface construction includes an anchoring section 3 that is obliquely arranged in the anchoring hole 2 that the rock formation 1 offers, and is fixed by the concrete and the anchoring hole 2, and the anchoring section 3 The anchorage length is 4-8m, and there are multiple anchor cables 4 rigidly connected to each other in the anchor section 3. In order to increase the connection strength between the anchor cables 4 and the anchor holes 2, the anchor cables 4 are cylindrical with a thin top and a thick bottom. Or a tapered structure, the anchor cable 4 is provided with a spacer 5 for increasing the connection strength with the anchor segment 3, the spacer 5 includes an annular connector with a connection cavity, and the a...

The invention discloses a concrete layer landslide prevention fixing device for a slope building. The concrete layer landslide prevention fixing device comprises an anchoring section, wherein the anchoring section is obliquely arranged in an anchoring hole formed in a rock stratum and fixed to the anchoring hole through concrete. The anchoring section is internally provided with a plurality of anchor cables which are in rigid connection. Partition frames are arranged on the anchor cables. A grouting pipe used for injecting concrete extends to the position 50-100 mm away from the bottom of the anchoring hole along the anchoring section. A slope base body is poured on the rock stratum, and a sleeve embedded in the slope base body is connected to the anchoring section and internally provided with a flexible prestress rope, wherein the flexible prestress rope is fixedly connected with the anchor cables and extends to the outer side of the sleeve. A prestress plate is movably connected to the position of an opening of the sleeve, and the prestress rope penetrates the prestres plate. An anchor head acting on the prestress plate is connected to the prestress rope. The concrete layer landslide prevention fixing device can improve the mechanical performance of a rock body and a slope, effectively prevent the rock body and the slope from moving and promote the rock body and the slope to be stable, and the purpose of renovating bedding rock, the landslide, a crag and dangerous rock.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to an anti-landslide fixing device for a concrete layer of a building on a slope. Background technique [0002] With the development of society, the construction industry has become inseparable from our life. During the construction process, it is often necessary to pour concrete slopes on the rock mass. The joint between the rock mass and the slope often has cracks or is not tightly combined. The slope Migration is prone to occur, and the overall stability of the slope and rock mass cannot be guaranteed. How to fundamentally improve the mechanical properties of the rock mass, effectively control the displacement of the rock mass, promote its stability, and achieve the goal of remediating bedding, landslides, dangerous rocks, and dangerous The purpose of the stone is the technical problem to be solved at present. Contents of the invention [0003] In order to solve ...
