Environment-friendly drain board

Abstract

The invention provides an environment-friendly drain board which comprises a board body and a filtering layer arranged on the board body in a covering mode. A plurality of hollow protrusions are arranged on the board body. The board body is made of melamino-formaldehyde resin, and the distributing rate of the hollow protrusions on the board body is larger than 80%. The filtering layer is made of geotechnical cloth, and the hole diameter of the geotechnical cloth ranges from 20 micrometers to 180 micrometers. The filtering layer and the board body can be combined in a bonding or heat sealing mode. The environment-friendly drain board has the advantages of being good in drain effect, low in machining cost, degradable, environmentally friendly and free of pollution, and saving energy.

Description

technical field [0001] The invention belongs to the field of new materials for civil engineering, and in particular relates to an environment-friendly drainage board. Background technique [0002] China has a vast territory and abundant resources. At the same time, China has a large population, and the availability of land resources has been very tight, and a lot of land needs to be transformed before it can be used. Among them, a large part of the land cannot be used because of the water storage of the soil. Therefore, people have thought of many methods for improving the water storage a long time ago. The traditional drainage method uses masonry tiles as the filter layer, and uses more pebbles or gravel as the filter layer to drain the water to the designated location. Modern people have invented drainage boards to drain water, and using drainage boards instead of pebbles to drain water can save time, labor and energy, save investment, and reduce the load of buildings. ...

Problems solved by technology

[0003] The plastic drainage boards currently used are mostly non-degradable materials such as polypropylene. After the foundation treatment is completed, these plastic drainage boards will exist underground for a long time, which will have a certain impact on the environment and affect the reuse of land. Not conducive to environmental protection

At the same time, some new drainage boards use environmentally friendly materials, but the manufacturing process is more complicated, the energy consumption is high, the strength, toughness and ductility of the drainage board cannot meet the standards, and the actual practicability is poor.
