Pile top buttress type retaining wall supporting structure and construction method

Abstract

The invention discloses a pile top buttress type retaining wall supporting structure and a construction method. The pile top buttress type retaining wall supporting structure comprises a pile and a buttress type retaining wall, the pile is buried within the range which is 2 m below an existing soil slope surface, the buttress type retaining wall is formed at the top of the pile through a connection beam, wherein a shingle of the buttress type retaining wall is vertically arranged on the connection beam, and a wall heel plate transversely extends towards the backfill soil side. The supporting structure combines the advantages of the pile and the buttress type retaining wall, the self stability against overturning of the supporting structure can be improved when the bearing capacity of the top edge of a slope or the bearing capacity of foundation soil is low, moreover, transverse pressure of slope high backfill soil to the supporting structure can be borne, and deformation and slippage are resisted.

Description

1. Technical Field [0001] The invention relates to a side slope filling support structure and a construction method, in particular to a pile-top buttress retaining wall support structure and a construction method. 2. Background technology [0002] In the construction of civil engineering, slope filling is a common project. In order to ensure the stability of the engineering structure, it is usually necessary to construct a supporting structure on the slope. The supporting structure often used in the treatment of slope filling mainly includes Cantilever type supporting pile structure and buttress type retaining wall structure. [0003] 1. Cantilever supporting pile structure [0004] In the current slope support, the cantilever support pile structure is widely used. It is a structure in which manual digging piles or bored piles are arranged in a straight line and connected by connecting beams to jointly resist lateral earth pressure or slope thrust. The advantage of cantilever supp...

Problems solved by technology

[0008] Since the structural stability of the buttress retaining wall is guaranteed by the gravity of the filling soil above the wall body and the wall heel plate, and the main function of the setting of the wall toe plate is to enhance its own anti-overturning stability and base contact stress, therefore, The requirements for the stability, bearing capacity and deformation resistance of the foundation soil are relatively high. When the foundation of the retaining wall is at the edge of the slope top, there may be situations where the stability of the slope and the bearing capacity of the foundation soil cannot be satisfied, and the safety cannot be guaranteed.
