Carbon fiber electroosmosis chain type vertical reinforcement structure and treatment method of soft foundation of carbon fiber electroosmosis chain type vertical reinforcement structure

Abstract

The invention discloses a carbon fiber electroosmosis chain type vertical reinforcement structure and a treatment method of a soft foundation of the carbon fiber electroosmosis chain type vertical reinforcement structure. The method comprises the steps that granular materials are wrapped with carbon fiber warp-knitted conductive nets to form net bags, the net bags are connected through carbon fiber strips to form a spatial regular tetrahedral structure, and the granular materials are construction waste recycled aggregate; after fully stirring the regular tetrahedral structure, sinking the regular tetrahedral structure into a vertical reinforcing body containing the double-helix ascending carbon fiber strip and the PVC drainage pipe; a gravel cushion layer is laid on the soft foundation to form a composite foundation, and the cushion layer is a gravel cushion layer where horizontal PVC drainage pipes are laid; the PVC drainage pipe and the horizontal PVC drainage pipe in the vertical reinforcing body are connected to form a complete drainage system; and the double-helix rising carbon fiber strip in the vertical reinforcing body is connected with a voltage-stabilizing direct-current power supply to form electro-osmosis accelerated drainage. The soft foundation treatment method can accelerate the drainage rate of the soft foundation, shorten the consolidation period and improve the bearing capacity of the composite foundation, and has the advantages of being environmentally friendly, easy to construct and the like.

Description

technical field [0001] The invention relates to the technical field of soft foundation treatment, in particular to a carbon fiber electroosmotic chain type vertical reinforcement structure and a soft foundation treatment method thereof. Background technique [0002] With the rapid development of my country's national economy, the country's continuous increase in infrastructure construction, my country's high-rise buildings, highways, and railway construction have achieved rapid development, and the construction waste generated at the same time cannot be properly disposed of, causing environmental pollution; soft soil foundation The problem has become increasingly prominent and has become one of the key factors affecting project quality, construction period and project cost. When dealing with weak soil foundations, the foundation soil needs to be drained and consolidated so that the foundation soil has a certain strength. Rigid pile composite foundations often have a large dif...

AI Technical Summary

Problems solved by technology

In the treatment of weak soil foundation, the foundation soil needs to be drained and consolidated to make the foundation soil have a certain strength. The rigid pile composite foundation often has a large difference in stiffness between the pile and the soil between the piles. After the foundation soil is drained and consolidated, a large amount of settlement will cause Negative friction resistance of the pile body will cause rigid pile failure, especially when the pile body cannot penetrate the deep and high water content foundation, the rigid pile treatment method cannot be used; Low, the pile body is prone to large lateral expansion, and the crushed stone filler is extruded laterally, which cannot play the role of foundation reinforcement. Although the injection of cement slurry into the crushed stone pile can improve the strength of the upper part of the crushed stone pile, it cannot treat the deep part. For gravel and soil between piles, the treatment effect of grouting method is significantly different due to the difference in soil properties between piles, the quality control is relatively difficult, and the treatment cost is high; the electroosmosis method is more environmentally friendly and efficient for soft soil foundation reinforcement, but it is not suitable for Only has drainage consolidation effect, long treatment period, limited treatment depth, and limited effect on improving the strength of soft soil foundation

Generally speaking, although there are many methods for soft soil foundation treatment, when it is treated, the above-mentioned traditional methods are used due to reasons such as long construction period, high cost, difficulty in controlling post-construction quality, and limited improvement of soft soil foundation strength. , the effect is not obvious in the process of dealing with deep soft soil foundation
