Soft soil foundation for preventing differential settlement of building foundation and construction method thereof

Abstract

The invention discloses a soft soil foundation for preventing differential settlement of a building foundation and a construction method of the soft soil foundation. According to the soft soil foundation, a building area of the soft soil foundation is changed into areas of an identical size, concrete slabs are poured on the periphery of the soft soil pieces with the identical size, concrete slurrycolumn holes are formed in the inner sides of the concrete slabs, then concrete slurry is injected, and soft soil at the top of the concrete slurry is replaced with a gravel filler, so that the overall performance of the soft soil is improved; and embedded concrete piles with different depths are arranged at the bottoms of buildings with different heights, and the middles and the tops of the bottoms of the embedded concrete piles are connected with each other, so that the stress area and the overall stability of the embedded concrete piles are improved, and the phenomenon that other buildingsincline or collapse due to sinking caused by the height difference is avoided. According to the method, the structures of the embedded piles of the buildings and the structure of the foundation workjointly, so that differential settlement of the foundation is reduced.

Description

technical field [0001] The invention relates to the field of construction, in particular to a soft soil foundation for preventing uneven settlement of building foundations and a construction method thereof. Background technique [0002] Soft soil foundation generally refers to the foundation soil with low shear strength, high compressibility and other bad properties. The common ones are natural silt and silty soil, miscellaneous filling soil formed by domestic garbage and industrial waste accumulated randomly by human beings, and flushing soil formed by hydraulic filling mud and sand. In recent years, with the development of my country's economic construction and the needs of external reforms, construction projects such as various factories, commercial buildings, hotels and restaurants, multi-storey and high-rise residences are being built all over the country, and there are fewer and fewer good building foundations. Some buildings can only be located on these bad sites. Fo...

Problems solved by technology

[0003] The characteristic of the soft soil foundation is that the settlement of the building is large and uneven, and effective measures can be taken to control the large settlement. The uneven settlement has many and complicated influencing factors, so it has become a problem for the current buildings to crack or seriously affect the use. The main cause of accidents, not only causing huge losses, but also affecting people's lives
