Safe supporting structure for foundation pit supporting in civil engineering

Abstract

The invention relates to the technical field of building, in particular to a safe supporting structure for foundation pit supporting in civil engineering. Aiming at the defects of simple supporting structures, unstable supporting strength and incapability of draining underground water existing in the prior art, the invention proposes the following scheme: the safe supporting structure comprises supporting plates and a supporting foundation, wherein the supporting plates vertically cling to the sidewall of a foundation pit, two fixed rings are welded on each of the upper edge and the lower edgeof one side, far from the sidewall of the foundation pit, of each supporting plate, the two fixed rings on each of the upper edge and the lower edge are on a straight line, and are symmetrically arranged, two first mounting recesses are reserved under the two fixed rings of the upper edge of each supporting plate, and two second mounting recesses are reserved in each supporting plate under the corresponding two first mounting recesses. According to the safe supporting structure, the supporting effect of the supporting plates on the foundation pit is enhanced, consequently, the shape of the foundation pit is kept undeformed, foundation pit collapse is prevented, and the foundation pit is more stable; the underground water in the sidewall of the foundation pit can be drained out via drainage slots, and ultimately flows into an urban sewer via a drainage channel, and thereby convenience is provided for subsequent construction.

Description

[0001] This patent application is a divisional application, the application number of the parent application is 2017101502155, and the application date of the parent application is March 14, 2017. technical field

[0002] The invention relates to the technical field of construction, in particular to a safety support structure for civil engineering foundation pit support. Background technique

[0003] The pit foundation is an earth pit excavated at the foundation design position according to the base elevation and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the nearby buildings, and the waterproof and drainage work should be done well. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to the relevant construction regulations. If the excavation is deep and there are buildings n...
