Concrete lattice wall and discrete material pile combined deep soft soil foundation reinforcement treatment structure and construction method

Abstract

The invention provides a concrete lattice wall and discrete material pile combined deep soft soil foundation reinforcement treatment structure and a construction method. A reinforced concrete lattice wall which is orthogonal in the transverse direction and the longitudinal direction is arranged on a deep soft soil foundation; discrete material piles such as gravel piles or sand piles are arranged in the center of the concrete lattice wall frame; the bottoms of the concrete lattice wall and the discrete material piles are located on a soft foundation bottom dense layer or weathered bed rock; and the horizontal permeable cushion layer is arranged at the tops of the concrete lattice wall and the discrete material piles. According to the deep soft soil foundation condition, the rigid reinforcing structure and the flexible reinforcing body are reasonably utilized to jointly reinforce the soft soil foundation, and meanwhile, the reinforcing treatment measure and method create conditions for accelerating drainage consolidation of foundation soft soil and improving the strength of the foundation soft soil, the strength, the bearing capacity and the deformation modulus of the soft soil foundation meet the requirements of an upper structure and a building. And the method is of great significance to a deep soft soil foundation treatment technology under complex conditions.

Description

technical field [0001] The invention relates to the technical fields of architecture, municipal administration, and water conservancy engineering, in particular to a deep soft soil foundation reinforcement treatment structure and construction method combined with concrete lattice walls and bulk material piles. Background technique [0002] Constructing heavy-loaded structures and buildings on deep soft soil foundations is an engineering technical problem often encountered in the fields of construction, municipal and water conservancy projects. The strength, bearing capacity and deformation modulus of soft soil foundations often cannot meet the stability and Therefore, foundation reinforcement measures must be taken to ensure the stability, safety and normal use of structures and buildings. For soft soil foundation, there are many treatment methods in engineering, such as direct excavation, pile foundation treatment, preloading consolidation drainage, grouting, dynamic compac...

AI Technical Summary

Problems solved by technology

The use of reinforced concrete walls can directly increase the strength and bearing capacity of the foundation by using the rigidity of the concrete plus the structure, but it cannot provide drainage channels for the deep soft soil, so it is difficult to use the later strength of the soft soil consolidation
