Concrete-steel structure mixed angle support construction method

Abstract

The invention discloses a concrete-steel structure mixed angle support construction method which sequentially comprises the following steps that slide-resistant piles and top beams are formed, specifically, the slide-resistant piles and the top beams are poured on the side of a road line side soil layer and the side of a subway line side soil layer, and the top beams are formed at the tops of the multiple slide-resistant piles; and early warning layer forming: forming an early warning layer on the slide-resistant pile and the top beam, wherein the early warning layer can observe that the supporting structure generates supporting deformation. When a vehicle running on a soil layer on the side of a road line and a soil layer on the side of a subway line causes supporting deformation of the supporting structure, due to the existence of the early warning layer formed by pouring reinforcing steel bars and concrete, cracking of the concrete on the early warning layer can be visually and rapidly observed through naked eyes, and the problem that deformation cannot be visually observed at present is solved, and the effect of early warning in advance is achieved.

Description

technical field [0001] The invention relates to a concrete-steel structure mixed angle support construction method, which belongs to the technical field of building construction. Background technique [0002] When building a high-rise building, it is necessary to deeply excavate the foundation of the building. Although the high-rise building can obtain a good foundation after deep excavation, it will also cause the danger of collapse of the foundation slope of the deep foundation pit, especially the deep foundation pit with a triangular shape. When the two sides correspond to highways and subway lines, the protection of deep foundation pit slope collapse is particularly important. [0003] In order to effectively protect the slope collapse at the triangular part of the deep foundation pit, the Chinese Patent Publication No. CN103967018B provides a horizontal shear structure for the corner support of the deep foundation pit, which uses corner support layers and columns to pro...

Problems solved by technology

[0003] In order to effectively protect the slope collapse at the triangular part of the deep foundation pit, the Chinese Patent Publication No. CN103967018B provides a horizontal shear structure for the corner support of the deep foundation pit, which uses corner support layers and columns to protect the triangular part of the deep foundation pit. Although the slope can be effectively protected, although the support can be realized, because the support body is made of steel structure, when the vehicles running on the road line or subway line cause the support structure to deform, there is a problem that the deformation cannot be observed intuitively, which is difficult play an early warning role
