The drainage board produced by the company is made of high-density polyethylene that is heated and pressurized to form a drainage channel that can not only create a drainage channel with a certain three-dimensional space support stiffness, but also A lightweight board that can store water. (Manager Wu of Drainage Board Manufacturer)
This kind of board itself has two comprehensive functions of water storage and drainage. The board has the characteristics of extremely high spatial rigidity, and its pressure resistance is obviously better than similar products (it can be tested through on-site tests to withstand The above high compressive load (Manager Wu of the drainage board manufacturer) can also withstand the extreme load conditions of mechanical rolling during the backfilling process of the planting roof. It has the functions of creating drainage within the layer, discharging the infiltration water in the soil, and storing some of the infiltration water
Due to the large area of the underground garage, its use function and the durability of the reinforced concrete structure require strict sealing and waterproofing. The thickness of the upper covering soil layer is often determined based on the needs of the plants being planted, so as to reduce the structural damage as much as possible. load, which forms a shallow basin shape (drainage plate manufacturer supplies Shijiazhuang garage greening drainage plate filter plate)
● Stable impermeable layer, communication with the general environment is blocked
● Deep-rooted plant roots extend horizontally in the basin Extension
● The dryness of the upper part of deep ponding water leads to the simplification of plant species
The shallow basin shape cannot meet the requirements of diverse planting ecology
What urban residential community green spaces need is an ecological environment with diverse plant species, and a broad Leafy trees have the best environmental cleaning effect. Therefore, community green spaces need to be created with broad-leaved trees, shrubs, and perennial herbs. The shallow basin shape obviously cannot meet the above requirements. Therefore, artificial intervention measures must be taken to artificial environment circulation system. (Manager Wu of Drainage Board Manufacturer )
The artificial environmental circulation system in the shape of a shallow basin uses special materials to establish a rapid water and gas flow circulation system.
In the early years, when material technology was underdeveloped, the artificial intervention system used river pebbles to build permeable Drainage layer and graded sand and gravel filter layer construct a soil and water conservation layer. (Drainage plate manufacturer supplies Shijiazhuang garage greening drainage plate filter plate)
The development of modern synthetic material technology provides a better solution for artificial environmental circulation systems in the shape of shallow basins. Convenient construction techniques use plastic raw materials to heat and press the water storage and drainage boards to construct the water storage and drainage layer. Polyester non-woven fabrics filter water and soil conservation. The manual intervention system is more flexible and lightweight. The system structure is designed from top to bottom as follows (Manager Wu of the drainage board manufacturer)
Artificially prepared planting soil layer, natural landfill
Natural soil base layer (compacted according to backfill requirements)
Irrigation system (pre-buried in the soil base layer)
Polyester non-woven fabric Soil and water conservation filter layer
Storage and drainage layer
Fine stone concrete waterproof protective layer
Waterproof layer (according to design)
Leveling (slope) layer
Garage roof reinforced concrete structure
(Manager Wu of Drainage Board Manufacturer) It can be seen from the above that using our water storage and drainage boards greatly reduces the tedious process, reduces the cost of materials and construction, and reduces the time cost of construction.
