Plastic drainage board_garage drainage board|Hohhot drainage board manufacturer, Manager Wu, /3/. Plastic drainage boards are also called garage drainage boards, building sandwich boards, water filter boards, permeable boards, etc. Plastic drainage boards are mainly used in greening projects: garage roof greening, roof gardens, vertical greening, sloped roof greening, football fields, golf courses. Municipal engineering: airports, road subgrades, subways, tunnels, landfills. Construction engineering: upper or lower floors of building foundations, interior and exterior walls of basements, roof anti-seepage and heat insulation layers, etc. The drainage board is mainly made of raw materials and is blow molded under high pressure. It is a kind of cylindrical or conical convex point with protrusions. The drainage board has a concave and convex hollow rib structure, which can quickly and effectively drain rainwater, greatly reducing or even eliminating the problem. The hydrostatic pressure of the waterproof layer can achieve active waterproofing through this active water conduction principle.

On the roofs of buildings that require greening and planting, waterproofing and drainage measures are usually required. Plastic drainage boards are mainly used for drainage. After the waterproof layer is completed, a layer of plastic drainage boards is laid on it, and then backfilled with planting soil to form an overhead layer at the bottom of the soil, which can smoothly remove excess water and reduce the load of the building in a timely manner. , while ensuring the growth of plants. The drainage board is made of a plastic bottom plate that is stamped into a conical protrusion (or hollow cylindrical porous platform). The top surface of the conical protrusion is glued with a layer of filtering geotextile to prevent soil particles from passing through, thereby avoiding obstruction of the drainage channel and making the drainage channel smooth. The traditional drainage method uses masonry and tiles as the filter layer, and uses more pebbles or gravel as the filter layer to drain water to designated locations. Replacing the cobblestone filter layer with drainage boards for drainage saves time, effort, energy, investment, and reduces the load on the building. A good drainage system plays an important role in the construction period of civil engineering and the normal use and life of the structure. The cylindrical porous drainage board and the geotextile also form a drainage system, thus forming a system with water seepage, water storage and drainage functions. Due to the large area of underground garages, their use functions and the durability of reinforced concrete structures require strict sealing and waterproofing. The thickness of the upper covering soil layer is often determined based on the needs of the plants planted to reduce the load on the structure as much as possible. , which forms a shallow basin shape. In the early years when material technology was underdeveloped, the artificial intervention system used river pebbles to construct a permeable drainage layer and a graded sand and gravel filter layer to construct a soil and water conservation layer. However, in this drainage method, due to the heavy weight of sand, gravel and cobblestones, the load on the roof of the building is increased. The gaps between the sand, gravel and cobblestones also allow plant roots to grow, which will inevitably pierce the waterproof layer.

How to construct the drainage board:
Clean up the garbage at the laying site and level the cement so that there are no obvious concavities and convexities on the site. Outdoor garage roofs and roof gardens need to have -r slopes.
.Roof greening and outdoor garage roof greening can be used with porous seepage pipes, which can drain the water discharged from the drainage board to nearby sewer pipes or nearby city sewers.
3. To prevent water seepage on the basement floor, raise the floor above the foundation, that is, make a layer of drainage board before making the floor, with the round protruding platform downward and blind ditches around it to prevent groundwater from coming up. , the seepage water naturally flows into the surrounding blind ditch through the space of the drainage plate, and then flows into the water collection pit through the blind ditch.

. To prevent water seepage in the inner wall of the basement, a drainage board can be laid on the main wall of the building, with the round protruding platform facing the main wall, and a single layer of wall built outside the drainage board or steel mesh powder cement used to protect the drainage. board, so that the space of the seepage board outside the wall flows straight down into the blind ditch and into the water collection pit.
. When laying drainage boards in any area, care must be taken not to allow dirt, cement, yellow sand and other garbage to enter the front space of the drainage board, and to ensure that the space of the drainage board is unobstructed.
. When the drainage board is laid, protective measures should be taken as much as possible. When laying the drainage board on the surface or in the outdoor garage, the backfilling work should be done as soon as possible to prevent the strong wind from blowing the drainage board and affecting the laying quality. The basement and interior wall waterproofing should be done as soon as possible. A good protective layer to prevent the drainage board from being damaged by people or objects.
. The backfill soil is clayey soil. It is ideal to lay 3-cm yellow sand on top of the geotextile, which is beneficial to the water filtration of the geotextile. If the backfill soil is a kind of nutritious soil or light soil, there is no need to lay it again. A layer of yellow sand, the soil itself is very loose and easy to filter water.
