Treatment structure and method of high-strength water-permeable fiber concrete pipe gravel core pile soft thick soil base

Abstract

The invention discloses a treatment structure of a high-strength water-permeable fiber concrete pipe gravel core pile soft thick soil base. The treatment structure of the soft base comprises high-strength water-permeable fiber concrete pipe piles, gravel, soft water-permeable blind pipes, water-permeable concrete pile followers, gravel cushion layers and two-way steel-plastic gratings. The high-strength water-permeable fiber concrete pipe piles are filled with the gravel, the soft water-permeable blind pipes are arranged in the high-strength water-permeable fiber concrete pipe piles, the water-permeable concrete pile followers are arranged at the upper ends of the high-strength water-permeable fiber concrete pipe piles, the gravel cushion layers are arranged above and around the water-permeable concrete pile followers, the two-way steel-plastic gratings are arranged on the middle portions and the upper portions of the gravel cushion layers, and the position on the two-way steel-plasticgrating on the uppermost layer is filled with roadbed soil and a roadbed. By means of the novel application and the novel process of a novel material, the soft soil base can be effectively treated athigh quality, the method is simple, the effect is excellent, the bearing force of the soil base is greatly improved, the construction period is greatly shortened, the engineering cost is reduced, andhigh economic benefits are increased.

Description

technical field [0001] The invention relates to a structure and method for treating soft and thick soil foundation of high-strength permeable fiber concrete pipe crushed stone core piles, and belongs to the technical field of road subgrade soft foundation treatment. Background technique [0002] Soft soil foundations are more common in areas with developed water systems, and the quality of soft foundation treatment has therefore become one of the most critical factors affecting project cost and roadbed construction quality in road construction. In the past roadbed soft foundation treatment measures, the main method used There are surcharge preloading, plastic drainage plate drainage consolidation, cement mixing piles, etc. These methods have certain advantages, but also some disadvantages. For example, the surcharge preloading method does not process the original foundation, but directly loads heavy objects such as soil, sand, water, etc. on it, and compresses the soil thro...
