Abstract

The invention discloses a reinforcement method for reducing differential settlement of a strip-shaped shallow foundation house. A strip-shaped shallow foundation of a house is replaced to a box raft deep foundation for reinforcing a settled house; and based on reinforcement, a bored pile and a pile top longitudinal beam integrally cast with the foundation are constructed for realizing the jacking rectification of the house. The reinforcement method is scientific and reasonable in planning, high in reliability, simple in construction structure, liable to realize the process, excellent in mechanical performances of a constructed house structure and capable of effectively reducing differential settlement of the house.

Description

technical field

[0001] The invention belongs to the technical field of civil engineering, in particular to a reinforcement method for reducing the uneven settlement of strip-shaped shallow foundation houses. Background technique

[0002] In this technical field, although there are many studies on the characteristics of the surrounding site deformation caused by the excavation of deep foundation pits in construction projects, and the impact on surrounding pipelines and adjacent buildings, such as the construction of subway stations, etc., for deep and weak sites, ground connections There are still relatively few studies on the impact of wall trenching construction and foundation pit earthwork excavation on multi-storey buildings adjacent to shallow foundations. Shallow foundation buildings with brick-concrete structure have poor tensile performance, while the foundations are often brick strip foundations, which have poor self-regulation ability and are extremely sensitive to ...
