Anchored pile reinforced earth retaining wall embankment for treating shoreside soft soil roadbed

Abstract

The invention relates to the technical field of shoreside soft soil roadbed treatment, and in particular relates to an anchored pile reinforced earth retaining wall embankment for treating soft soil roadbed with an underlying inclined hard layer. The anchored pile reinforced earth retaining wall embankment comprises a cushion layer (9) and an embankment (10), wherein the embankment further comprises support piles (1), bearing piles (4), pile caps (5), pull rods and pre-stressed anchor rods (6); the support piles (1) are arranged at the deep end of the inclined hard layer; the bearing piles (4) are arranged at the shallow end of the inclined hard layer; the pile caps (5) are connected with the top ends of the support piles (1) and the bearing piles (4); the pull rods are crossly fixed in the pile caps (5); one end of each of the pre-stressed anchor rods (6) is fixed in the inclined hard layer; the other ends of the pre-stressed anchor rods (6) are fixed on the pile caps of the bearing piles at the soft soil shallow end, a horizontal bidirectional reinforcing body (8) and a reinforced earth retaining wall (3); and a row of support piles (1) at the deepest end of the inclined hard layer (12) are fixedly connected with one another by virtue of a connecting beam (2). The stability of the foundation is greatly improved.

Description

technical field [0001] The invention relates to the technical field of shore soft soil foundation treatment, in particular to an anchor-pull type pile bearing reinforced soil retaining wall embankment for treating soft soil subgrades with inclined hard layers underneath. Background technique [0002] In engineering fields such as highways and railways, pile-supported reinforced embankments are widely used in subgrade projects in deep or limited soft soil areas at home and abroad, and good results have been achieved. The way of the existing pile-supported reinforced embankment is: first set the pile body in soft soil, then cast in-situ reinforced concrete pile cap at the top of the surface pile, then lay horizontal reinforcement and cushion on the pile cap, and finally place the pile cap on the pile cap. Construction of embankment on horizontally reinforced cushion. If the thickness of the soft soil is limited and there is a horizontal hard layer under the soft soil layer, t...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an anchor-pull type pile-bearing reinforced soil retaining wall embankment for treating soft soil subgrades on the bank, which solves the problem of soft soil with thick sides when using the prior art to treat soft soil subgrades with inclined hard layers underneath. The displacement of the outer pile is large, prone to bending or buckling damage, and the uneven settlement of the embankment is large, and the stability is difficult to guarantee, etc.
