The company is a large comprehensive enterprise known domestic production of geosynthetics and import and export enterprises specialized in the production, research and development of geosynthetics and new composite materials. Mainly produces operating YN crack control paste, crack paste way geogrid way geogrid, fiberglass geogrid, warp knitting geogrid, steel plastic geogrid, mining geogrid 3D geonet mat, high strength geonet, geocell, engineering fiber, plastic blind ditch, soft water pipe, short wire geotextile, filament geotextile, geomembrane, composite geomembrane and other engineering materials. Its products are mainly used in the aerospace, aviation, military, chemical, oil; roads, railways, coal mining, water conservancy, electric power, water and soil conservation, and environmental greening and infrastructure areas, has been widely used in a number of national key projects such as highways, railways . Drainage plate is made of polystyrene (HIPS), or is a polyethylene plastic floor after stamping tapered projection (or a hollow cylindrical porous) formed. The top surface of the conical projections bonding layer filter geotextile to prevent soil particles by in order to avoid blocking of the drainage channel pore smooth drainage. The traditional way of drainage to use masonry tile as a guide filter layer, using more pebbles or gravel as a filtering layer, the water discharged to the designated location. The drainage board replaced pebbles treatment layer to drain the province, effort and energy saving, saving investment, but also to reduce the load of the building. Features: good drainage system has an important role in normal use and service life of the civil construction cycle and structures. HW drainage board porous tube to form an effective sparse drainage system, a drainage system of cylindrical long and short drainage board with geotextile to form a system with water seepage, water storage and drainage function. Uses garden project: the garage roof green roof garden, soccer fields, golf courses, municipal engineering baths engineering: road embankment, subway tunnel construction project: building foundations upper or lower, basement and external wall, roof seepage and insulation layer traffic engineering: highway, railway embankment, dikes and revetment layer laying procedures: 1. laying the scene to clean up the garbage, cement screed, so that the site no obvious bump at the outdoor garage roof and roof garden need 2-5 ‰ slope. Green roof and outdoor garage roof greening with the use of the porous tube, so could concentrate discharged to the nearby water pipes under or near the city sewer discharge water drainage board. Basement ground seepage water, the basis of the above overhead ground, that is, do floor before now to do a layer of drainage board, round projections downward, around the left blind ditch, able to come up groundwater seepage natural inflows through the drainage board space surrounded by blind ditch, and then flows into the sump through the blind ditch. 4. Basement interior wall seepage water, laying drainage board on the main wall of the building, round projections for the main wall. Puzzle to protect the water supply and drainage board, a layer of single wall or steel mesh powder cement wall outside seepage board space straight under inflow blind ditch directly caused by sump drainage board. In any Lot laying drainage board must pay attention: Do not let dirt, cement, sand, and other garbage into the front space of the drainage board, ensure smooth drainage board space. Good protection measures as much as possible when the laying of the drainage board level or outdoor garage laying drainage board should do backfill work as soon as possible, to prevent large wind tangled drainage board affect the laying quality. Basement and interior walls waterproof to do protective layer as soon as possible to prevent drainage board destruction is the person or thing. 7. Backfill soil, Shop 3-5 cm above the geotextile sand as an ideal, conducive to the geotextile filtration; backfill a nutritive soil or light soil no longer laying a layer of sand, soil is very loose easily treatment. 8 Drainage Board laying edge and the edge of the right to take the next 1-2 fulcrum, the two backplane can also touch Sarkozy, above geotextile lap, you can just keep the soil drainage channel into the drainage board, drainage flow . Construction specifications, in a dry, airy environment store drainage board to prevent exposure, away from sources of ignition. 2, please stand up or lie flat drainage protection board, not tilted or cross cross pressure, stack height should not exceed 3 floors, avoid heavy object heap pressure. Laying flat natural downslope or laying in accordance with the flow. The single shop geotextile lap guarantee 150cm, avoid moving the lap joints with rubber or sand compaction, and then backfill, the first layer of backfill guarantee tamping the next step only after stratification backfill must be compacted. The alias of plastic drainage with drainage board, wavy, harmonica type shape. Drainage board is combined with the advantages of the foreign brands drainage board, according to the geological conditions in China developed advanced soft ground and super soft Reinforcement new materials with single-hole cross section, smooth drainage, light weight, tensile compressive strength characteristics. Drainage board the middle plastic extrusion Xinban, is drainage with skeleton and channel, the section was parallel cross on both sides of the parcels of non-woven geotextile filter layer, the core band played the supporting role and infiltrated water filter layer discharged upward, silt, silt-quality soil, the hydraulic fill unsaturated cohesive and miscellaneous fill drainage consolidation method the soft ground treatment good vertical channel, greatly reducing the soft soil consolidation. Drainage board works: Drainage Board flapper machine inserted into the soft ground, in the upper part of the pre-pressure loads, the gap soft ground water discharged by the drainage board upper bedding sand layer or level of plastic pipes, elsewhere discharge, accelerated soft ground consolidation. In the soft ground treatment, drainage board design, the basic construction equipment with bags of sand wells. The drainage board applications: domestic and international highway, railway, airport, power plant, yard, ports, land reclamation, sewage treatment plants, garbage landfill, Reclamation land, water conservancy and hydropower, Pier construction works in soft foundation treatment project . Such as the coastal areas of Tianjin, Lianyungang, Shanghai, Hangzhou, Ningbo, Wenzhou, Fuzhou, Xiamen, Zhanjiang, Guangzhou, Kunming, Wuhan, Nanjing and other mainland regions. Drain Boards to Consolidate Soft Ground advantages: 1. Treatment drainage flow, drainage effect is guaranteed. 2. Material has good strength and ductility for ground deformation capacity without affecting the drainage performance. Drainage board section size vaccination drainage board little disturbance to the foundation. 4 in ultra soft ground the flapper construction. Construction of fast, short construction period, each card machine daily Flashboard more than 15,000 meters lower cost than the bags of sand well. Drainage consolidation method for reinforcing the deep soft ground, from the technical and economic considerations, the drainage board is almost the only economic, effective and feasible method. Drainage board various models applicable: SPB-A-type depth SPB-B-type soft ground in the 0 to 15 m vertical drainage depth of 15 to 25 meters depth of the soft ground vertical drainage SPB-C type 25 ~ SPB-D-type vertical drainage within 35 m of the soft ground depth of 35 meters above the soft ground vertical drainage
