Foundation pit supporting structure

Abstract

The invention relates to a foundation pit supporting structure which comprises a soil nailing wall arranged in a foundation pit, a drainage pipe is inserted into the soil nailing wall, the soil nailing wall is provided with a supporting plate used for supporting the soil nailing wall, the supporting plate is provided with a first water inlet pipe, a supporting device used for abutting against the supporting plate is arranged in the foundation pit, and the supporting device comprises a vertical rod, a transverse rod and a water collecting barrel. The transverse rod is vertically arranged on the vertical rod and faces the supporting plate, a sliding rod is movably arranged in the transverse rod in a penetrating mode, the transverse rod is provided with an open groove communicating with the interior of the transverse rod, and the water collecting barrel is coaxially arranged below the transverse rod in a sleeving mode and is slidably connected to the vertical rod; the upper end of the vertical rod is rotationally connected with a fixed pulley, a connecting rope with the two ends connected with the water collecting barrel and the sleeve respectively is in lap joint in the fixed pulley, and the water collecting barrel is communicated with the upper end of the supporting plate through a water passing pipe. The foundation pit slope supporting structure has the effect of improving the strength of foundation pit slope supporting.

Description

technical field [0001] The application relates to the field of foundation pit construction engineering, in particular to a foundation pit supporting structure. Background technique [0002] At present, the foundation pit 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. [0003] In the related art, for foundation pits that are not excavated too deep, soil nail walls are generally used to support the slope of the foundation pit. Soil nail wall is an in-situ soil reinforcement technology. The slope of the foundation pit...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, when the water level in the side slope of the foundation pit is not smooth and the water level is high, the inventor believes that there is a defect that the soil nail wall bears a large lateral pressure and easily causes the side slope of the foundation pit to collapse.
