Problems solved by technology

[0003] During the construction of some foundation pits, due to changes in the surrounding environment of the foundation pit, or due to project needs, it is necessary to deepen the foundation pit that is about to be constructed. At this time, the original foundation pit support structure has been formed and cannot be changed. The overall stiffness and anti-overturning ability of the pit support structure become weaker

Abstract

The invention discloses a foundation pit supporting reinforcing device which comprises a stiffness jet grouting pile and a jet grouting reinforcement soil body used for being attached to one side of a supporting pile. The stiffness jet grouting pile is arranged in the jet grouting reinforcement soil body and comprises a stiffness body and a jet grouting body attached to the outer surface of the stiffness body. Due to the fact that the jet grouting reinforcement soil body and the stiffness jet grouting pile are arranged on one side of the supporting pile, the resistance of the soil body at the bottom of a foundation pit is strengthened, the supporting pile is effectively prevented from deforming in the working process, and the integral rigidity and the anti-overturning ability of the deepened foundation pit supporting structure are improved. Compared with other reinforcing pile bodies, the construction period of the stiffness jet grouting pile is shorter, and the foundation pit supporting reinforcing device is rapidly and effectively achieved.

Description

technical field [0001] The invention relates to the technical field of foundation pit construction, in particular to a support and reinforcement device for foundation pits. Background technique [0002] With the increasing shortage of urban land, the pace of basement construction is also accelerating, and foundation pit support has become an important link in the excavation of underground structure foundation pits. At present, support piles are widely used as the foundation pit support structure in foundation pit construction to prevent deformation of the surrounding environment of the foundation pit and collapse of the foundation pit, and ensure smooth progress of engineering construction and construction safety. [0003] During the construction of some foundation pits, due to changes in the surrounding environment of the foundation pit, or due to project needs, it is necessary to deepen the foundation pit that is about to be constructed. At this time, the original foundati...
