Application of drainage plate in planting roof
With the rapid development of urban construction, urban land resources are increasingly tight, the government pays more and more attention to the development and utilization of underground space, the awareness of urban environmental construction is also constantly enhanced, in order to increase the green area of the city, the planting roof has been developed. Planting roofing is a form of greening supplemented by planting soil, planting plants in containers or planting templates to cover the building roof or underground building roof.
After rain, the rainwater infiltration is absorbed by the soil. After the soil is saturated, the water seepage will accumulate on the planting roof, and the long-term deposition of a large amount of water seepage will cause the plant root decay and the leakage of the weak parts of the waterproof layer, so it is necessary to design the water prevention and drainage system. Therefore, the planting roof needs to be solved in two technical problems, that is, how to prevent water seepage and prevent the plant root system from growing on the building, and the drainage plate planting roof system can solve the above two problems.
The drainage plate is made of the polymer synthetic material plastic bottom plate after stamping out the conical platform or convex point, and the top surface of the conical platform is matched with a layer of geotextile to prevent the soil particles from passing, so as to prevent the channel obstruction and make the hole drainage smoothly. Replacing the traditional pebble water filter layer with drainage board can shorten the construction time, save investment and reduce the building load, but also resist the plant root thorns and protect the building and waterproof layer.
The drainage plate produced by our company has excellent elongation rate, strong tensile and compressive strength, stable performance, can effectively control the expansion caused by external factors, to achieve effective waterproof and prolong the service life of the waterproof layer. The use of a firm construction connection method (hot melt welding), can effectively protect the drainage, waterproof layer. The waterproof project to do drainage, prevention, the rainwater quickly discharge, greatly reduce the water pressure on the waterproof layer.
It can also be matched with a rainwater collection system to discharge, collect and use rainwater, which can be used for planting roof plants, and can also be collected for other purposes, saving water resources and creating more value.
In the process of urbanization construction, a large number of infrastructure construction in the city is bound to conflict with the greening land. The planting roof, as a greening form that does not occupy the ground land, has solved this contradiction very well. Therefore, the planting roof has a good development prospect. Our high-quality drainage board products will also become the power for the development of the planting roof, and our company will always provide product and technical support for the development of the urban environment.
