Abstract

The invention relates to a foundation pit supporting and retaining structure and method combined with a high-pressure jet grouting technology. The structure comprises an enclosure structure arranged around the periphery of a foundation pit and used for supporting the foundation pit. Reinforcing bars are implanted into the enclosure structure from the side face, close to the foundation pit, of the enclosure structure. The reinforcing bars are attached to the side face, close to the foundation pit, of the enclosure structure. Concrete is jet-grouted to the side face, close to the foundation pit, of the enclosure structure through the high-pressure jet grouting technology, and a retaining barrier is formed. The reinforcing bars are anchored by the retaining barrier. The foundation pit supporting and retaining structure and method have the beneficial effects that the reinforcing bars are implanted into supporting piles,, the concrete is jet-grouted to the inner side face of the foundation pit through the high-pressure jet grouting technology, and the retaining barrier is formed, so that the universality of the foundation pit supporting and retaining structure is improved, and the precipitation effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a foundation pit support water retaining structure and method combined with high-pressure rotary jetting technology. Background technique [0002] In the process of building structure construction, the construction operation of foundation pit support and dewatering is generally based on site survey information, geological conditions, water level, etc., adopts slope protection support, soil nail support, support pile support and support pile plus anchor cable and other composite support measures. [0003] Generally, the foundation pit support and dewatering construction often has a large foundation pit area, and the precipitation cannot achieve full coverage, which often causes the water flow outside the foundation pit to impact the support structure, resulting in increased safety hazards of the foundation pit, and even engineering hidden dangers such as foundation p...
