Shallow soft soil foundation solidification structure and construction method thereof

Abstract

The invention discloses a shallow soft soil foundation solidification structure which comprises a pile nailing assembly, the pile nailing assembly comprises a pile pipe, a nail head, a fixing frame and fixing rings, the nail head is fixedly connected to one end of the pile pipe, the upper end and the lower end of the pile pipe are fixedly sleeved with the two fixing rings, and a plurality of circular openings are evenly formed in the side wall of the pile pipe; the multiple partition assemblies are arranged between the two nail pile assemblies and used for partitioning soft soil, each partition assembly comprises a partition plate, a filter plate and a reinforcing plate, the partition plate is slidably clamped between the fixing frames of the two nail pile assemblies through a clamping assembly and is made of a waterproof hard material, a mounting groove is formed in one side of the partition plate, and the filter plate is arranged in the mounting groove. The reinforcing plate is fixedly arranged in the mounting groove, the filter plate is fixedly connected to a groove opening of the mounting groove, and a plurality of parallel filter grooves are formed in the surface of the filter plate. Through combined use of a drainage consolidation method and a pile machine method, the structure is strengthened, and meanwhile the service time is prolonged.

Description

technical field [0001] The invention relates to the technical field of soft soil foundation solidification, in particular to a shallow soft soil foundation solidification structure and a construction method thereof. Background technique [0002] Soft soil is a general term for a type of soil, and does not refer to a specific soil. In engineering, soft soil is often subdivided into soft cohesive soil, silt soil, silt, peat soil and peat, etc., with high natural water content. , Large natural void ratio, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, large disturbance, poor water permeability, complex layered distribution of soil layers, and different physical and mechanical properties between layers larger features. The bearing capacity and deformation of soft soil foundations often cannot meet the design requirements, so foundation treatment measures should be taken to improve the strength of the foundat...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that during the use of the single drainage consolidation method in the prior art, after the drainage is completed, the surrounding soil is not reinforced, causing the surrounding soil to contain a large amount of water again due to the transfer of water. , reduces the curing effect, and maintains a short curing period, and the single pile driver method is prone to the disadvantages of deflection and loosening of the pile body due to the flow of soft soil during use, and a shallow layer is proposed Solidified structure of soft soil foundation and its construction method
