Carbon fiber electroosmotic chain type vertical reinforcement structure and its soft foundation treatment method

Abstract

The invention discloses a carbon fiber electroosmotic chain type vertical reinforcement body structure and a treatment method for its soft foundation. It includes: wrapping the granular material with a carbon fiber warp-knitted conductive mesh to form a net bag, connecting the net bag with carbon fiber strips to form a regular tetrahedral structure in space, and the granular material is recycled aggregate from construction waste; after fully stirring the regular tetrahedral structure, sinking Into the vertical reinforcement body containing double-helix carbon fiber strips and PVC drainage pipes; laying sand and gravel cushions on the soft foundation to form a composite foundation, the cushion is sand and gravel cushions for laying horizontal PVC drainage pipes; connecting vertical reinforcement The PVC drainage pipe in the body and the horizontal PVC drainage pipe constitute a complete drainage system; the double-helix rising carbon fiber strips in the vertically reinforced body are connected to a regulated DC power supply to form electroosmotic accelerated drainage; the soft ground treatment method of the present invention It can accelerate the drainage rate of soft foundation, shorten the consolidation period, improve the bearing capacity of composite foundation, and has the advantages of environmental protection and simple construction.

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
