Internal and external supporting structure of building foundation pit

Abstract

The invention discloses an internal and external supporting structure of a building foundation pit. The internal and external supporting structure comprises a stabilizing frame, wherein a driving mechanism is arranged at the top of the stabilizing frame; a transmission mechanism is arranged at the center of an inner cavity of the stabilizing frame; supporting plates are arranged on the front, rear, left and right sides of the transmission mechanism; the front and rear groups of supporting plates are first supporting plates; the supporting plates on the left and right sides are second supporting plates; telescopic mechanisms are arranged on the front, rear, left and right sides of the upper end of the outer part of the transmission mechanism and the front, rear, left and right sides of the lower end of the outer part of the transmission mechanism; and a positioning mechanism is arranged at the bottom of the transmission mechanism. The internal and external supporting structure is reasonable in structural design, facilitates good internal and external supporting of the building foundation pit, reduces the possibility of collapse of the building foundation pit and avoids delay of the project progress.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an internal and external support structure of a building foundation pit. Background technique [0002] Construction engineering refers to the engineering entity formed through the construction of various housing buildings and their ancillary facilities and the installation activities of the supporting lines, pipelines and equipment. The earth pit dug, and the building foundation pit is the space excavated from the ground downward for the construction of the underground structure of the building (structure). [0003] At present, in construction projects, excavated square building foundation pits usually do not have good internal and external supports, which may easily cause the building foundation pit to collapse and delay the progress of the project. Therefore, we propose a kind of building foundation pit internal and external support structure. Contents of th...
