Method for reinforcing soft soil foundation structure through bamboo grouting piles

Abstract

The invention provides a method for reinforcing a soft soil foundation structure through bamboo grouting piles. The method achieves the reinforcement of the soft soil foundation through hollowing outbamboo joints of raw bamboos, drying the raw bamboos, reinforcing the ends of the raw bamboos, brushing an anticorrosive material, installing pile tips, driving the raw bamboos, grouting the raw bamboos and laying a mattress layer. According to the method, renewable and fast-formed raw bamboos are fully utilized, materials are convenient to obtain, the materials are green and renewable, sustainable development is achieved, the construction method is simple, fast and low in cost, and the raw bamboo grouting pile composite foundation comprehensively utilizes the effect of a pile body, the effectof a cushion layer and the compaction effect and is widely applied to reinforcement of the soft soil foundation structure.

Description

technical field [0001] The invention relates to a reinforced foundation structure, in particular to a method for reinforcing a soft soil foundation structure with raw bamboo grouting piles, and belongs to the field of civil engineering. Background technique [0002] In the construction of highways and railways, the routes often pass through soft soil sections such as paddy fields and cross-river ditches. The bearing capacity of shallow soft soil layers in these sections often cannot meet the design requirements of structures. Reasonable and economical methods must be used to carry out soft soil foundation Reinforcement treatment. [0003] Soft soil is mainly silt and muddy soil, which has the characteristics of low bearing capacity, high compressibility, high water content and low permeability coefficient. If it is not treated, it will be difficult to use. The general methods for dealing with soft soil foundations include replacement filling method, sand (gravel) pile compa...

AI Technical Summary

Problems solved by technology

The replacement method has the disadvantage of high cost

The sand (gravel) pile compaction method requires special steel pipes and equipment for pressing and pulling pipes, and the construction method is relatively complicated.

For heavy hammer tamping method, dynamic tamping method, rotary spraying method and other methods, construction needs to use large-scale special machinery and equipment, while small bridges and culverts in road network projects have small engineering quantities and require frequent transportation of machinery and equipment, making it impossible to carry out large-scale construction. The cost is too high, it is difficult to play its due benefits
