Abstract

The invention relates to the technical field of construction, in particular to a safety support structure for building pit foundation construction. For the defects that a support structure is simple, the support strength is unstable, and underground water cannot be drained in the prior art, the scheme is provided, the safety support structure comprises a support plate and a support foundation, the support plate is vertically and tightly attached to the side wall of a pit foundation, and the upper edge and the lower edge of the side, away from the side wall of the pit foundation, of the support plate are each provided with two fixing rings in a welding manner. The two fixing rings on each of the upper edge and the lower edge are both located on the same straight line and are symmetrically formed. Two first mounting grooves are reserved in the positions, below the two fixing rings, of the upper edge of the support plate. Second mounting grooves are reserved in the portions, below the two first mounting grooves, of the support plate. By the adoption of the safety support structure, the support function of the support plate on the pit foundation is enhanced, the shape of the pit foundation is kept unchanged, the collapse of the pit foundation is avoided, and the pit foundation is more stable; and the underground water on the side wall of the pit foundation is drained through a drain groove and finally flows to an urban sewer through a drain canal, and convenience is provided for later construction.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a construction safety support structure for a building pit foundation. Background technique [0002] The pit foundation is a soil pit excavated at the base design position according to the base elevation and the base plane size. Before excavation, the excavation plan should be decided according to the geological and hydrological data and the conditions of the buildings near the site, and waterproof and drainage work should be done. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the size of the slope shall be determined according to the relevant construction regulations. If the excavation is deep and there are nearby buildings, the pit foundation wall support method, the shotcrete wall protection method, the large-scale pit foundation or even the underground diaphragm wall and the column-type bored pile interlocking method can be u...
