Connecting structure for foundation pit stand column and foundation pit bidirectional support

Abstract

The invention belongs to the field of foundation pit stand columns, and particularly relates to a connecting structure for a foundation pit stand column and a foundation pit bidirectional support. Theconnecting structure comprises a stand column base, wherein a connecting piece is fixedly connected to the upper end of the stand column base; a stand column is connected to the middle of the connecting piece in a penetrating mode; a supporting disc is fixedly connected to the top of the upper end of the stand column; a disc fixing frame is fixedly connected to the bottom of the supporting disc;a lifting assembly is fixedly connected to the lower end of the disc fixing frame; a limiting assembly is fixedly connected to the upper end of the supporting disc; and a transverse supporting rod anda longitudinal supporting rod are fixedly connected in the limiting assembly. According to the connecting structure, a limiting piece is arranged, the longitudinal supporting rod and the transverse supporting rod are fixed in the limiting piece through a limiting right-angle plate, so that the longitudinal supporting rod and the transverse supporting rod are connected in pairs, the stability of the foundation pit bidirectional structure can be enhanced conveniently, and the longitudinal supporting rod and the transverse supporting rod are not in direct contact in the limiting piece, the direct contact connection is unstable, and the risk caused by collapse is caused.

Description

technical field [0001] The invention belongs to the field of foundation pit columns, in particular to a connection structure for bidirectional support between foundation pit columns and foundation pits. Background technique [0002] In order to ensure the safety and stability of the underground space formed by the excavation of the ground during the construction of the underground structure, the retaining structure, groundwater control, environmental protection and other measures are called foundation pit engineering. Foundation pit engineering is a system engineering integrating geological engineering, geotechnical engineering, structural engineering and geotechnical testing technology. Its main contents: engineering survey, support structure design and construction, earthwork excavation and backfilling, groundwater control, information construction and surrounding environmental protection, etc. It will be limited by the site conditions and the surrounding environment, so ...

AI Technical Summary

Problems solved by technology

[0004] The traditional foundation pit beam installation method is to set the horizontal support rods and longitudinal support rods on the same horizontal plane, and the horizontal support rods and longitudinal support rods set on the same horizontal plane may be twisted and deformed during the construction process, resulting in structural failure. Collapse and other dangers, and even cause accidents, and the support disc of the existing separate device is not equipped with a lifting structure, so that the device can only meet the specific construction environment, resulting in poor environmental adaptability of the device
