Building foundation pit supporting device with sinking-preventing and water-removing functions

Abstract

The invention relates to the technical field of building foundation pits and discloses a building foundation pit supporting device with sinking-preventing and water-removing functions. The building foundation pit supporting device comprises a base. The base comprises a rotating column, an arc-shaped groove, a columnar groove, a filter screen and an upper metal sheet. The outer side of a second roller is connected to a second belt, the upper end of an air bag is connected to a lower metal sheet corresponding to the upper metal sheet, chutes are separately formed in the back side and the right side of a cone-shaped column, a push rod is connected in the cone-shaped column, and the outer side end of the push rod is connected to an extension plate. The integral gravity of a water tank is increased to push a sliding plate to move downward, the sliding plate drives the cone-shaped column to move downward through a connecting rod, the chutes in the cone-shaped column extrude the push rod to move outward, and the push rod drives the extension plate to move outward. The structure increases the stress area of the base, so that a condition that a foundation pit wall supporting device is easyto incline and sink as soil is softened is avoided, and the supporting effect of the building foundation pit is further guaranteed.

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 ...
