Jiuhe new plastic protective drainage board is made of poly benzene ethylene （ HIPS ）Or Drain board product introduction The water storage and drainage board is made of polystyrene (HIPS) or polyethylene plastic base plate, which is stamped into a conical boss (or hollow cylinder Shaped and porous). Application of drainage board: soft foundation treatment projects in domestic and foreign expressway, * * *, airport, power plant, storage yard, port, reclamation, sewage treatment plant, landfill, reclamation, water conservancy and hydropower, wharf construction and other projects, drainage consolidation improves the foundation bearing capacity gardens Project: garage roof greening, roof garden, roof greening, football field, golf course, bathing beach project and other municipal projects; road subgrade, subway tunnel and other construction projects: upper or lower layer of building foundation, interior and exterior walls of basement, roof anti-seepage and thermal insulation layer, etc.
Purpose and construction scheme of drainage board:
Plastic drainage board is widely used in various construction projects with the characteristics of water diversion, drainage and protection.
It is applied to greening projects: garage roof greening, roof garden, vertical greening, inclined roof greening, football field, golf course, etc.
Municipal engineering: airport, road subgrade, subway, tunnel, landfill.
Construction works: upper or lower layers of building foundation, interior and exterior walls and baseplates of basement, roof, roof anti-seepage and thermal insulation layer, etc.
Water conservancy projects: seepage prevention of reservoirs, reservoirs and artificial lakes.
Traffic engineering: highway, * * * subgrade, embankment and slope protection layer.
5 Laying procedures 1. Clean up the garbage on the laying site and level the cement so that there is no obvious concave and convex spots on the site. The outdoor garage roof and roof garden need to have 2-5 ‰ slope making.
2. Use, so that the water discharged from the drainage board can be collectively discharged to the nearby sewer or the nearby urban sewer.
3. The basement floor is impervious to water. The floor is elevated above the foundation, that is, before the floor is made, a drainage board is made. The round platform is downward, and blind ditches are left around to prevent the underground water from flowing up. The seepage naturally flows into the blind ditches around through the space of the drainage board, and then flows into the sump through the blind ditches.
4. For water seepage prevention of the basement wall, drain boards can be laid on the main wall of the building, and the round ledge faces the main wall. A layer of single wall shall be built outside the drainage board or steel mesh powder cement shall be used to protect the drainage board, so that the space of the seepage board outside the wall flows straight down into the blind ditch to the sump.
5. When laying drainage boards in any section, attention must be paid to: do not allow dirt, cement, yellow sand and other garbage to enter the front space of the drainage board to ensure that the space of the drainage board is unblocked.
6. Protective measures shall be taken as far as possible when the drainage board is laid. The backfilling work shall be done as soon as possible when the drainage board is laid on the surface or in the outdoor garage to prevent the drainage board from being disturbed by strong wind from affecting the laying quality. The protective layer shall be made as soon as possible to prevent the drainage board from being damaged by people or objects.
7. The backfill is cohesive soil. It is ideal to pave 3-5 cm yellow sand on the geotextile, which is conducive to the filtration of geotextile; If the backfill is a nutrient soil or light soil, there is no need to lay a layer of yellow sand, and the soil itself is very loose and easy to filter water.
8. When the drainage board is laid, the side and the right are overlapped with 1-2 fulcrums, and the two bottom plates can also be aligned. The upper part is overlapped with geotextile. As long as no soil enters the drainage channel of the drainage board, the drainage can be kept smooth. There are many manufacturers of drainage boards in Shandong, with complete products and reasonable prices. It is a better place to buy drainage boards.
