As urban car culture, survival and development of environmental awareness, the development of underground construction without reducing ground green area is the trend of modern urban construction, which formed a new ecological environment - planting platform basement on a shallow basin ecology environment. In order to achieve the ecological environment of plant diversity, the need for intervention in regulating artificial environment, that set of people for good drainage and ventilation systems. "Sanmenxia planting basement drain" - "Hebi drainage protection board" alternative drainage layer; drainage protection board instead of the traditional practice of 15cm-20cm thick ceramic gravel / gravel drainage layer, thereby reducing the roof load, the degradation of the project cost, between architectural space . HDPE very nature; drainage protection board itself ingredient is high density HDPE, high density plant roots puncture resistant HIPS itself, the application planted roof drainage board to prevent damage to the plant roots waterproof layer, roof structure, thereby preventing the roof from the fundamental leakage; stable high-density HDPE product performance degradation of its own life of 300 years, can be done with the life of the building; high-density HDPE resistance to chemical corrosion, the natural environment and general industrial environments acids, bases, salts can not causing corrosion damage. "Sanmenxia planting basement drain" - "Hebi drainage protection board" 1, in the dry, ventilated storage environment drainage board, to prevent exposure, away from fire; 2, please stand up or lie flat drainage protection board, not tilted or Cross horizontal pressure, Do not stack more than three layers, not heavy heap pressure; 3, when laying should be smooth natural downslope or according to the laying of water; 4, single lap lay geotextile guarantee 150cm, lap Avoid using plastic or compacted sand movement, and then backfill, the first layer of compacted backfill guarantee only after the next, layered backfill must be compacted. "Sanmenxia planting basement drain" - "Hebi drainage protection board" Timber has a very high spatial rigidity characteristics, resistance superior to similar products (by field test test), can withstand high compressive loads 400Kpa above, at the same time planted roof can withstand extreme loads backfill process of mechanical rolling. Build drainage board has an inner drainage layer to create, within the emission of soil water infiltration, storage reservoir section permeate other functions, as opposed to the previous generation of the drain has the following disadvantages: Northern drought, build drainage board can be filled with water, is conducive to the growth of vegetation ; build drainage board bump thick side walls, so the larger compressive strength, can reach 40T, far larger than the plastic tabs (HDPE drainage board high-density, high impact HIPS drainage board), plastic drainage mat and other similar Products (RCC can actually experiment), to meet the construction requirements of backfill and uptime requirements.
