Product Name: Green Drainage Board Model NO.: 500mm*500mm Usage: Outdoor, Indoor Color: Green Certification: ISO Function: Anti-static, Fireproof, Heat Insulation, Sound-Absorbing, Waterproof Surface Treatment: Film Coated Ceiling Tile Type: PVC Ceilings Thickness: 2.0mm Material: HDPE Ceiling Tile Shape: Roll Type: Waterproof Roll Material Trademark: xin hang Transport Package: Strapping Specification: 2*20 Origin: Laiwu District, Jinan City, Shandong Province, Chi HS Code: 5603939000 Product Description The plastic drainage board is made of polystyrene (HIPS) or polyethylene (HDPE) as raw material, the plastic bottom plate is punched into a conical protrusion or a convex point of a stiffener (or hollow cylindrical porous). After continuous innovation and research and development, the raw material has been greatly improved and changed. Now it is made of PVC as raw material, and its compressive strength and overall flatness have been greatly improved Lifting, width 1-3m, length 4-10m or moreAlayer of filter geotextile is glued to the top surface of the conical protrusion to prevent soil particles from passing through, so as to avoid blocking the drainage channel and smooth drainage of the channel. The traditional way of drainage uses bricks and tiles as the filter guide layer, and more pebbles are used 30 draining board Or gravel as a filter layer to discharge water to a designated place. However, using drainage board instead of pebble filter to drain water can save time, labor, energy, investment and load of buildings. A good drainage system plays an important role in the construction period of civil engineering and the normal service life of structures. The drainage board and porous seepage pipe form an effective drainage system, and the cylindrical multi empty drainage board and geotextile also form a drainage system, thus forming a system with water seepage, water storage and drainage functions.Water diversion and drainage There are concave and convex hollow vertical bar structures in the waterproof and drainage protection board, which can quickly and effectively lead out rainwater, greatly reduce or even eliminate the hydrostatic pressure of the waterproof layer. Through this active water diversion principle, the active waterproof effect can be achieved. Waterproof performance: Polyethylene (HDPE) polystyrene (PVC) waterproof and drainage protection plate material itself is a good waterproof material. By adopting reliable connection mode, the waterproof and drainage board becomes a good auxiliary waterproof material. Protection and protection Waterproof and drainage protection board can effectively protect the structure and waterproof layer, and resist all kinds of acid and alkali in the soil and root thorn of plants. When the outer wall of basement is backfilled, it can protect the building and waterproof layer from damage. Sound insulation, ventilation and moisture-proof function: The laboratory data show that the HDPE PVC waterproof and drainage protection board can effectively reduce the indoor noise of 14dB, 500Hz, and has obvious noise reduction and sound insulation function. When the waterproof water guide plate is used on the ground or wall, it can also play a good role in ventilation and moisture-proofGreening project: roof greening, roof garden, vertical greening, inclined roof greening, football field, golf course. Municipal Engineering: airport, road subgrade, subway, tunnel, landfill. Construction Engineering: the upper or lower layer of the building foundation, the interior and exterior walls and baseplates of the basement, as well as the roof, roof anti-seepage and thermal insulation layer, etc. Water conservancy project: reservoir seepage prevention, reservoir, artificial lake seepage prevention. Traffic engineering: highway, railway subgrade, dike and slope protection layer[Greening project: roof greening, roof garden, vertical greening, inclined roof greening, football field, golf course. Municipal Engineering: airport, road subgrade, subway, tunnel, landfill. Construction Engineering: the upper or lower layer of the building foundation, the interior and exterior walls and baseplates of the basement, as well as the roof, roof anti-seepage and thermal insulation layer, etc. Water conservancy project: reservoir seepage prevention, reservoir, artificial lake seepage prevention. Traffic engineering: highway, railway subgrade, dike and slope protection layerLaying procedure edit 1. The garbage and cement on the site shall be cleaned and leveled so that there is no obvious concave and convex on the site. The outdoor garage top and roof garden shall have 2-5 ‰ slope making. 2. It can discharge the water discharged from the drainage board to the nearby downpipe or nearby urban sewer. 3. The basement ground is impermeable, and the ground is elevated above the foundation, that is to say, before the ground is made, a layer of drainage plate is made, with the round protruding platform downward and blind ditch left around, so that the ground water cannot come up. The seepage water naturally flows into the blind ditch around through the space of the drainage plate, and then flows into the sump through the blind ditch. 4. The basement wall is impermeable, and the drainage board can be laid on the main wall of the building, with the round protruding platform facing the main wall. A layer of single wall is built outside the drain board or steel wire mesh cement is used to protect the drain board, so that the space of the seepage board outside the wall flows into the blind ditch and the sump directly. 5. When laying the drainage board in any section, attention must be paid to: do not let the soil, cement, yellow sand and other garbage enter the front space of the drainage board to ensure the smooth space of the drainage board. 6. When the drainage board is laid, the protection measures shall be taken as far as possible. When the drainage board is laid on the surface or outdoor garage, the backfilling work shall be done as soon as possible to prevent the laying quality from being affected by the strong wind. basement and interior wall waterproofing should be protected as soon as possible to prevent the drainage board from being damaged by people or objects. 7. The backfill is clayey soil. It is ideal to lay 3-5cm yellow sand on the geotextile, which is conducive to the filtration of geotextile. If the backfill is a kind of nutrient soil or light soil, there is no need to lay another layer of yellow sand, and the soil itself is very loose and easy to filter water. 8. When the drainage board is laid, it can be lapped down to 1-2 fulcrum at the right side of the edge, or the two bottom plates can be aligned. The geotextile is used to lap the top of the drainage board. As long as there is no soil entering the drainage channel of the drainage board, the drainage can be kept smooth.
