A kind of pile plate U-shaped support load-reducing structure and construction technology

Abstract

The invention belongs to the technical field of load reduction application of composite retaining building structures, and relates to a pile-slab U-shaped retaining load-reducing structure and construction technology, including rectangular cross-section anti-sliding piles, load-reducing blocks, flexible filler EPS boards and rectangular steel plates; There are multiple anti-slide piles with rectangular cross-section; the load-reducing blocks are parallel to the anti-slide piles with rectangular cross-section and are fixedly connected with the anti-slide piles with rectangular cross-section; The cross-section anti-slide pile forms a solid U-shaped support and load-reduction structure in cross section; the flexible filler EPS board is filled inside the U-shaped support and load-reduction structure and fits with the rectangular steel plate; the U-shaped support and load-reduction structure Stretch from the stable soil to the unstable soil from top to bottom. The invention provides a pile plate U-shaped support load-reduction structure and construction technology which can greatly reduce the earth pressure on the back of the wall to achieve the load-reduction effect, and the construction technology is relatively simple.

Description

technical field [0001] The invention belongs to the technical field of load-reducing application of composite retaining building structures, and relates to a retaining load-reducing structure and a construction process, in particular to a pile plate U-shaped retaining load-reducing structure and a construction process. Background technique [0002] The retaining structure is widely used in civil engineering, railway, highway transportation and water conservancy and hydropower projects. With the development of economic construction and science and technology, the requirements for retaining building structures are getting higher and higher. At present, there are few measures for load reduction analysis and load reduction design involving retaining structures, which need further development. Due to the wide application of the retaining structure, its structure type and application position become more important, and its load-reducing performance and mechanism should be further ...

AI Technical Summary

Problems solved by technology

The existing retaining structures have the following deficiencies in load reduction: (1) lack of corresponding load reduction theory; (2) lack of corresponding load reduction methods; (3) lack of corresponding load reduction construction techniques

A large number of retaining walls are used in the support structure, which does not help in load reduction, and produces a huge waste of resources and affects the construction
