Embodiment Construction

[0021] The present invention will be further described below in conjunction with the embodiments, and the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other used embodiments obtained by persons of ordinary skill in the art without creative efforts all belong to the protection scope of the present invention.

[0022] In conjunction with the accompanying drawings, the new anti-seismic retaining and backfilling composite structure of the present invention includes an L-shaped retaining wall 2 installed on the pile foundation 1. As a preferred method of the present invention, the pile foundation 1 adopts a double-row structure, and the pile Foundation 1 is buried to the bearing layer 0.5m. The retaining wall 2 includes a straight wall 22 and a base plate 21 installed on the pile foundation 1. The straight wall 22 and the base plate 21 are connected together to form an L-shaped...

Abstract

The invention belongs to the technical field of slope supporting, and discloses a novel anti-seismic retaining backfilling composite structure for solving the problems that an existing retaining structure is high in construction cost and prone to sedimentation, and potential safety hazards exist. The novel anti-seismic retaining backfilling composite structure comprises an L-shaped retaining wallarranged on a pile foundation. The retaining wall comprises a straight wall and a bottom plate arranged on the pile foundation. The straight wall and the bottom plate are connected together to form the L-shaped stop wall. The upper portion of the bottom plate is filled with a rubble layer. Cavities between the rubble layer and the slope body and between the straight wall and the slope body are filled with foam light concrete. The novel anti-seismic retaining backfilling composite structure has the beneficial effects that the stop wall settlement deformation is little, the wall lateral pressureis small, and the construction period is short.

Description

technical field [0001] The invention belongs to the technical field of slope supports, and in particular relates to a novel anti-seismic retaining and backfilling composite structure, which is used for filling roadbeds of roads and railways. Background technique [0002] When roads and railways are constructed at the toe of steep slopes in soft soil areas, it is often necessary to use retaining structures to close the slope to ensure the stability of the roadbed. Soil fillers are often used for backfilling and rolling treatment behind traditional retaining structures. However, due to the high density of the soil itself, the additional force on the lower foundation is large, and the lateral soil pressure on the vertical arm of the retaining wall is also relatively large, which is likely to cause retaining. Due to engineering problems such as wall instability, the size of the retaining structure is relatively large during design, resulting in long construction period and high ...
