Novel plastic drainage plate

Abstract

The invention relates to a plastic drainage board used in the treatment of soft soil foundation, which is a new type of plastic drainage board. The new type of plastic drainage board is composed of a cross-shaped core board and a filter membrane, wherein the cross-shaped core Composed of , protrusions, drainage channels, and a cross-shaped joint center, this new type of high-efficiency anti-bending plastic drainage board can prevent bending and clogging in the soil, increase the contact area with the soil to accelerate drainage, and is very environmentally friendly. That is, with the cylindrical joint point as the center, paste the surface of the cross-shaped core plate and the filter membrane, which can increase the strength of the plastic drainage plate and prevent bending and clogging; Channels increase the number of drainage paths, which is conducive to the drainage of water; the materials used in the new type of high-efficiency and anti-bending plastic drainage boards are degradable materials, which will degrade and disappear after a period of time, which is conducive to the redevelopment and utilization of land.

Description

technical field [0001] The invention relates to a plastic drainage board used in the soft soil foundation treatment process, in particular to a novel plastic drainage board. Background technique [0002] At present, the vacuum preloading method and the vacuum-surcharge combined preloading method are widely used in engineering as economical, efficient and practical soft soil foundation treatment methods. Up to now, bagged sand wells and plastic drainage boards are generally used as vertical drainage bodies. Among them, plastic drainage boards are often preferred because of their convenient construction and economical benefits. The traditional belt-shaped or round-tube plastic drainage board, because the drainage board has a single shape and the overall strength is not high, it is easy to be squeezed by the soil during the drainage process, causing it to twist and bend, which leads to the obstruction of the drainage path of the plastic drainage board , the drainage efficiency...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the existing drainage boards that are easily bent by the extrusion of the soil, which is not conducive to the recycling of land, and provide convenient connection to external equipment, environmentally friendly materials used, strong bending resistance of the drainage board, and three-dimensional drainage channels. A new type of plastic drainage board with large contact area with soil unit and fast drainage efficiency
