Double-row pile foundation pit reinforcement structure

Abstract

The invention discloses a double-row pile foundation pit reinforcement structure. The double-row pile foundation pit reinforcement structure comprises a supporting structure consisting of supporting piles positioned at the side walls of foundation pits and crown beams positioned at the top ends of the supporting piles, and also comprises anchorage piles which are arranged parallel to the supporting piles; the anchorage piles and the supporting piles are arranged at predetermined distance and are anchored into a soil body outside the foundation pits; the anchorage piles are fixedly connected with the supporting piles through pull rods. According to the double-row pile foundation pit reinforcement structure, the anchorage piles and the pull rods are added on the basis of the original supporting structures to form an anchorage-type double-row pile supporting structure. The structure is reinforced by fully utilizing the original supporting structure; the pivot span of the existing supporting structure is reduced; the anti-bending capacity is improved; the integrity and the overall rigidity of the overall supporting system are enhanced; the pressure distribution of the original supporting structure is adjusted; the bearing capacity of the original supporting structure is improved; meanwhile, the double-row pile foundation pit reinforcement structure provided by the invention has the characteristics of quick and high-efficiency reinforcement, and low cost, can realize segmented construction, is convenient and quick, has a remarkable reinforcement effect, and is convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a double-row pile foundation pit reinforcement structure. Background technique [0002] The foundation pit refers to the space below the ground excavated for the construction of the foundation and basement of buildings (including structures). The foundation pit is a temporary project, and its function is to provide a space so that the foundation construction can be carried out according to the position specified by the design. [0003] Foundation pit support refers to the support, reinforcement, maintenance and protection measures adopted for the side wall of the foundation pit and the surrounding environment in order to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. In the prior art, row pile support is a common form of support. However, in the actual construction process, the supporting structure of...

Problems solved by technology

However, in the actual construction process, the supporting structure of the foundation pit is often damaged when the load-bearing pressure is too large or the conditions of the surrounding environment and groundwater change suddenly, and the soil instability or excessive deformation occurs, which affects the surrounding environment of the foundation pit and the underground Different degrees of adverse effects on the structure
