High-rise building steel-concrete foundation structure capable of reducing settlement and construction technology

Abstract

The invention discloses a high-rise building steel-concrete foundation structure capable of reducing settlement. According to the high-rise building steel-concrete circular pile foundation structure, by arranging an adjusting ring, a connecting body, a stabilizing assembly and a locking structure, when circular piles are constructed, the circular piles at all construction sites can be kept on the same horizontal plane, further, the balance stress in the later period is ensured, the problem of settlement of the circular pile foundation during later use is solved, the service life of the circular pile foundation is prolonged, and the construction engineering quality is improved; and according to the construction technology of the high-rise building steel-concrete foundation structure capable of reducing settlement, a base, auxiliary assemblies and positioning structures are arranged to share pressure borne by the circular pile foundation, the base has a good stabilizing effect, then the stability of the circular pile foundation is guaranteed, the resistance of the circular pile foundation to external factors is improved, the sedimentation problem can be further solved, and the effect is obvious.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a settlement-reducing steel-concrete foundation structure and construction technology for high-rise buildings. Background technique [0002] The foundation refers to the soil or rock mass that supports the foundation under the building; the soil layer used as the building foundation is divided into rock, gravel soil, sand, silt, clay and artificial filling; the foundation includes natural foundation and artificial foundation (Composite foundation) Two types; natural foundation is a natural soil layer that does not need reinforcement by humans; artificial foundation requires reinforcement by humans, common stone chip cushion, sand cushion, mixed lime soil backfill and then compacted, etc., subsoil refers to It is the part of the soil that is affected by the load of the upper structure; the soil or rock mass that bears the full load of the building under the foundatio...

AI Technical Summary

Problems solved by technology

[0003] The building foundation of prior art usually is that reinforced concrete structure is main body, and the problem that often occurs in its construction process is foundation settlement, and foundation settlement refers to the subsidence of the foundation surface caused by the compaction of the foundation soil layer under the action of additional stress; Large settlement, especially uneven settlement, will cause the building to tilt and crack so that it cannot be used normally. The solution is usually to simply compact the foundation soil, but its flatness is difficult to ensure consistency. During the construction work, it will lead to uneven stress, which will easily cause local foundation settlement. Therefore, the effect is poor and cannot meet the actual construction needs
