Anchored row pile and anchorage wall combined retaining structure

Abstract

The invention discloses an anchored row pile and anchorage wall combined retaining structure. The anchored row pile and anchorage wall combined retaining structure comprises supporting row piles, ribbed soil retaining plates, a soil supporting plate among piles, anchor cables, anchor shaping pull rods and anchorage plates, wherein the ribbed soil retaining plates are shaped in trapezoidal structure with narrow top and wide bottom, one ends of the anchor shaping pull rods are fixed with the anchorage plates, and the other ends of the anchorage plates are fixed on reinforced concrete rib columns. The anchored row piles are combined with the anchor shaping pull rods and the ribbed soil retaining plates on the upper portion, lateral pressure of side slope mass is effectively resisted, and meanwhile, by the aid of the combined structure of the anchor shaping pull rods and the ribbed soil retaining plates, the problem that a lately filled soil layer is low in pulling resistance is solved, side-direction strength of the lately filled and compacted soil mass is fully utilized, length and quantity of the anchor cables are greatly reduced, and height of the row piles is simultaneously reduced. By the aid of the anchored row pile and anchorage wall combined retaining structure, engineering cost is saved, and construction progress is simultaneously accelerated.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a composite retaining structure of anchor-drawn piles and anchorage walls. Background technique [0002] In the process of building construction, it is often encountered that unstable slopes and newly filled slopes are reinforced. The conventional method is to set up full-length support piles and anchor rods (anchor cables) within the entire height range of the slope. Combined with the soil support plate between the piles to form a retaining structure to prevent the deformation and collapse of the loose slope. When slope support is carried out in some newly filled sites, due to the loose structure of the newly filled soil, it cannot provide sufficient frictional force and gripping force with the anchoring body of the anchor rod (anchor cable). And the change of the load at the top of the slope, the anchor rod (anchor cable) of the retaining structure will fail due t...

AI Technical Summary

Problems solved by technology

The invention can not only effectively support the loose slope body, but also solve the problem of low pullout resistance of the newly filled soil layer, make full use of the lateral strength of the newly filled soil layer when the soil is compacted, and save The amount of anchor rod (anchor cable) is reduced, and at the same time, the supporting and supporting functions of the anchor and row piles and the supporting function of the anchor retaining wall are fully utilized, and a good protection effect on the collapsed body is realized.
