A building foundation pit support device with anti-subsidence and water removal

Abstract

The invention relates to the technical field of building foundation pits, and discloses a building foundation pit supporting device with anti-subsidence and water removal, including a base, and the base includes: a rotating column, an arc-shaped groove, a cylindrical groove, a rectangular Groove, filter screen and upper metal sheet, the outside of the second roller is connected with the second belt, the upper end of the airbag is connected with the lower metal sheet corresponding to the upper metal sheet, and the rear and right sides of the tapered column are provided with chute respectively , the inside of the tapered column is connected with a push rod, and the outer end of the push rod is connected with an extension plate. The increase of the overall gravity of the water tank pushes the sliding plate to move downward, and the sliding plate drives the conical column to move downward through the connecting rod. The chute on the conical column squeezes the push rod to move outward, and the push rod drives the extension plate to move outward. This structure increases the stress-bearing area of ​​the base, thereby avoiding soil softening, and the foundation pit wall support device is prone to inclination and depression, which further ensures the support effect of the building foundation pit.

Description

technical field [0001] The invention relates to the technical field of building foundation pits, in particular to a building foundation pit support device capable of preventing subsidence and removing water. Background technique [0002] Foundation pit refers to the space below the ground excavated for the construction of building foundation and basement. The soil 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 nearby, the foundation pit wall support method can be used. In the ...
