Water permeable coreboard

Abstract

The present invention discloses a water-permeable core plate, andi s characterized by that the described water-permeable core plate is a kind of hard space grid with more than one bent shannel, and the water-permeable plate made of said water-permeable core plate has the advantages of high permeable efficiency and high drainage efficiency, and can be extensively used for civil engineering drainage, underground drainage and removing water percolation of various structures.

Description

1) Technical field [0001] The invention relates to a water-permeable plate used for removing water seepage underground and inside a structure, in particular to a core plate in the water-permeable plate. Two), background technology [0002] At present, in civil and agricultural projects, it is often necessary to drain the interior of soil or structures, such as lowering the groundwater level, intercepting and draining groundwater, draining the back of retaining walls, and abutments. There are two types of permeable panels commonly used: one is the soft permeable pipe, that is, the permeable pipe with a helical spring covered with a permeable layer, such as figure 1 As shown, the soft permeable pipe made of helical spring core tube has the following disadvantages: 1. Poor mechanical performance: no matter whether the soft permeable pipe is buried in gravel or buried in soil, it cannot withstand lateral loads; 2. The water permeability efficiency is not high: the soft permeabl...

There are two types of permeable panels commonly used: one is the soft permeable pipe, that is, the permeable pipe with a helical spring covered with a permeable layer, such as figure 1 As shown, the soft permeable pipe made of helical spring core tube has the following disadvantages: 1. Poor mechanical performance: no matter whether the soft permeable pipe is buried in gravel or buried in soil, it cannot withstand lateral loads; 2. The water permeability efficiency is not high: the soft permeable pipe is set with closely arranged warp and weft threads for reinforcement, which greatly reduces the water permeability efficiency; The three-dimensional mesh permeable core board, as shown in Figure 2, has the following disadvantages: 1. The porosity is small, resulting in small water permeability and low drainage efficiency; 2. The waste of materials is serious, and a lot of messy materials are used to form products with low drainage efficiency

[0003] The Chinese invention patent specification with the notification number CN2238852Y discloses an elastic-plastic soft permeable pipe. The permeable pipe includes a pipe wall support and a water-permeable filter layer, wherein the inner support of the pipe wall is composed of a spiral spring steel wire and a plastic clip. , the water-permeable filter layer is wound by two layers of soft fabric inside and outside, and its disadvantages are also mentioned above: low water-permeable and drainage efficiency

Notification No. CN2399447Y also discloses a drainage plastic blind ditch material in the specification of Chinese invention patent. and low drainage efficiency
