Geotechnical engineering deep foundation pit supporting beam frame structure and using method

Abstract

The invention discloses a geotechnical engineering deep foundation pit supporting beam frame structure and a using method, and belongs to the technical field of constructional engineering. The geotechnical engineering deep foundation pit supporting beam frame structure comprises a connector and a supporting frame enclosing purlin, wherein a containing groove is formed in a pressure applying block; a second rotating shaft and a third rotating shaft are fixedly connected in the containing groove; a triangular frame is rotationally connected to the second rotating shaft; a positioning cylinder is rotationally connected to the third rotating shaft; the triangular frame is rotationally connected with the positioning cylinder through a second connecting rod; a reinforcing rod is rotationally connected in the positioning cylinder; one end of the reinforcing rod is fixedly connected with a triangular plate, and the other end of the reinforcing rod is rotationally connected with a conversion base; the triangular frame is rotationally connected with the conversion base through a first connecting rod; and a driving part used for driving the triangular frame to rotate is arranged in the containing groove. According to the geotechnical engineering deep foundation pit supporting beam frame structure and the using method, through the expandable containing type steel supporting beams, the use number of the steel supporting beams is greatly reduced, the hoisting frequency is reduced, the safety is improved, and transferring is facilitated.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a support beam frame structure and a use method of a deep foundation pit in geotechnical engineering. Background technique [0002] Deep foundation pit refers to a project where the excavation depth exceeds 5 meters or the depth does not exceed 5 meters, but the geological conditions, surrounding environment and underground pipelines are particularly complicated. Foundation pit engineering mainly includes the design and construction of foundation pit support system and earthwork excavation, which is a highly comprehensive system engineering. It requires close collaboration between geotechnical and structural engineering technicians. The foundation pit support system is a temporary structure and is no longer needed after the completion of the underground construction. Both the foundation pit and the foundation groove are used to build the foundation of the build...
