Slope treatment scheme adopting adit-type face-to-face anchorage

Abstract

The invention discloses a slope treatment scheme adopting adit-type face-to-face anchorage. The slope treatment scheme comprises the following steps that first, the geology of a slope needing to be reinforced is surveyed, the treatment scheme is formulated, and an engineering drawing is drawn; second, anchorage cavities with the designated number are driven in the designated positions of the two sides of the slope towards the interior of the slope, and the positions of anchorage holes are marked in the slope surface of the slope and inside the anchorage cavities through a theodolite; third, the anchorage holes are drilled in the slope surface by a drilling machine, anchor cables penetrate into the anchorage holes, the ends, exposed out of the slope surface, of the anchor cables are fixed to the slope surface through outer anchorage heads, and the anchor cable ends in the anchorage cavities are fixed through inner anchorage heads; and fourth, the outer anchorage heads are mutually connected and fixed through steel bars, and the inner anchorage heads are connected through steel bars; and fifth, drainage holes are driven towards the tops of the anchorage cavities at equal distances inthe mode of being perpendicular to the anchorage cavities. In short, the slope treatment scheme has the advantages of complete scheme, convenient and rapid construction, high safety and the like.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a slope treatment scheme using a flat hole type anchor. Background technique [0002] Anchor cable means that when the main cable is anchored in the side hole in the suspension bridge, the main cable should be divided into many strands of steel bundles and anchored in the anchor spindle respectively. These steel bundles are called anchor cables. The anchor cable is fixed on the slope surface through the outer end, and the other end is anchored in the stable rock mass within the sliding surface, passing through the prestressed steel strand on the sliding surface of the slope, directly generating anti-sliding resistance on the sliding surface, increasing the anti-sliding Frictional resistance keeps the structural surface in a compact state to improve the integrity of the rock mass of the slope, thereby fundamentally improving the mechanical properties of the rock m...

AI Technical Summary

Problems solved by technology

[0003] However, the anchor cable often fails due to the relaxation and failure of the surrounding rock at the anchoring end, the aging of the anchoring agent, the progressive failure of the stress concentration at the anchoring end, and the creep and relaxation of the anchor cable, which in turn induces slope problems.
