Novel water storage and drainage plate

Abstract

The invention discloses a novel water storage and drainage plate, which has strong bearing capacity and good mechanical property and is convenient for forming and multifunctional. The novel water storage and drainage plate is a double-sided concave-convex pyramid plate made of plastic. In the pyramid plate, a series of double-sided concave-convex staggered truncated pyramid supporting bodies are processed on a whole plate / sheet by using a method of die pressing, plastic absorption, rolling and the like; the adjacent truncated pyramid units are mutually communicated through a V-shaped groove; and during construction, a geotextile filter layer is spread on the water storage and drainage plate. The novel water storage and drainage plate has excellent mechanical property, can bear load, resist trample, store and discharge water, regulate water quantity and steam, preserve moisture and hold water and soil, is easy for construction and simple and convenient to assemble, can be widely applied in the fields of building engineering, urban greening and the like, is simple in manufacture, is suitable for large-scale batch production, and is low in cost.

Description

technical field [0001] The invention relates to the field of construction and greening engineering, in particular to a novel storage and drainage board. Background technique [0002] At present, drainage boards made of plastic materials are widely used in construction fields, such as: drainage under roofs and foundations, waterproofing of inner and outer walls of underground projects, greening and drainage of golf courses, roofs, and roadsides. However, the existing drainage boards have relatively poor structural strength and bearing capacity, and are easily crushed and damaged when they are crushed by heavy objects or subjected to excessive force, which seriously affects the performance of water storage and drainage. In addition, most of the existing storage and drainage boards have a single function, which can only drain water and have no water storage function. In terms of moisturizing and water retention, especially in field planting, roof greening and other projects, du...

AI Technical Summary

Problems solved by technology

However, the structural strength and bearing capacity of the existing drainage boards are relatively poor. When they are crushed by heavy objects or subjected to excessive force, they are very easy to be crushed and damaged, which seriously affects the performance of water storage and drainage.

In addition, most of the existing storage and drainage boards have a single function, which can only drain water and have no water storage function. In terms of moisturizing and water retention, especially in field planting, roof greening and other projects, due to the low ability of self-regulation due to thin soil layers, the planted Plants and flowers are also prone to dryness and death

At present, there are also products on the market that can store and drain water, but they are all made of small pieces spliced ​​together. The manufacturing cost is high, the construction is complicated, and it is easy to cause leakage.
