Hefei seepage drainage pipe general specifications blind blind drainage canal seepage 50MM, 80MM infiltration blind drainage tube, 100MM infiltration blind drainage tube, 150MM infiltration blind drainage tube, 200MM infiltration blind drainage pipes and other specifications, special specifications can be customized. Blind infiltration drainage pipe construction method, trench excavation, filling gravel cushion, shop filter. 2, the laying of plastic blind ditch material, the filters were wrapped blind ditch body. 3, the plastic blind ditch plastic blind ditch butt or miter. 4, in vitro blind ditch gravel backfill and compaction. The advantage of infiltration blind drainage tube: (1) high compressive strength, good pressure resistance, and the response is good, there is no reason of overloading or failure of other causes drainage problems; (2) surface of the plastic blind ditch average opening. hole rate of 90-95%, far higher than other similar products, the most effective collection of soil water seepage, and timely collection drain away; (3) has in the soil, the water never degradation, anti-aging, anti-UV high temperature, corrosion resistance, keeping unchanged the characteristics of a permanent material; (4) plastic blind ditch membrane can be chosen depending on the soil conditions, and fully meet the engineering requirements, and to avoid a single membrane products uneconomic shortcomings; (5) hypobaric plastic blind ditch (about 0.91 to 0.93), site construction and installation is very convenient, decrease labor intensity, greatly accelerate the construction efficiency; (6) flexibility, ability to adapt to the soil deformation, can avoid. overload, to 基烈 deformation and fracture differential settlement reasons set drainage failure caused the accident; (7) under the same conditions set draining effect plastic blind ditch material costs, transportation costs, construction costs are lower than other types. blind ditch, overall costs low. Infiltration blind drainage pipe engineering applications: 1. Highway, railway embankment and shoulder drainage blind ditch plastic material laying roads, railway embankment and road shoulder, timely collect and drain away the foreign seepage and rain softened ground to prevent and reduce the differential settlement. Plastic blind ditch laying railway embankment material can prevent mud-pumping diseases. 2. Retaining the back drainage (vertical, horizontal drainage) retaining wall on the back is the easiest part of the catchment. Retaining wall at the back of the plastic blind ditch material is arranged, it may go after discharge water seepage wall, lowering the water table behind the wall to prevent soil softened, eliminating stagnant water pressure to ensure the stability of the retaining wall. 3. Tunnels, underpasses and drainage tunnels, underpasses leakage often occurs in the outer waterproof layer, laying plastic blind ditch material, forming a set of drainage network channel, a way out for water seepage, seepage water to drain away in time, can effectively solve the concrete cracks leakage and other causes. 4. Slopes, embankments and other slope drainage laying plastic blind ditch material in the soil slope, when there is rain and snow, collect the water to drain away from the slopes penetrate plastic blind ditch, protect vegetation, soil from being washed away, avoid soil erosion and prevent landslides landslides. 5. Soft ground treatment level drainage treatment of soft foundation consolidated drained (such as a plastic plate drainage law, Sand Wick, etc.), so there is usually coarse sand cushions as horizontal drainage, the use of plastic blind ditch material partially replace sand pad layer, then drain better, can greatly reduce the cost of materials and construction of high efficiency, no waste. 6. Playgrounds, golf courses, airports, parks and other green laying irrigation drainage ditch plastic blind material in playgrounds, golf courses, airports and other venues of turf, forming the drainage network system. When precipitation can promptly penetrate the ground water to drain away, to prevent ground water muddy. In the dry season the soil can be carried out under irrigation. 7. Heap of coal fields, landfills, compost sites and other venues in the heap of coal field drainage, landfills, compost sites and other venues are arranged below the plastic blind ditch material, and the formation of the drainage network, so that the moisture content is discharged and given percolation centralized processing, which prevents water pollution on the surrounding environment. 8. Decompression of the drainage blanket construction method reduced construction method in the 1980s to promote a new technology, is in the bottom and side walls of buildings lay buried part plastic blind ditch (paved or interval shop), laid on top of the geotextile separation layer, by catchment pipes connected thereto will lead to the infiltration of water pumped water storage in the building, through the pump the water to drain away. Water is also available for use in buildings, quickly ruled out due to underground water seepage, lower the water table, reducing groundwater buildings buoyancy and water pressure, effectively improve the security and stability of the building. 9. Agriculture, horticulture underground irrigation and drainage systems below the depth of the root crop laying plastic blind ditch material, forming irrigation network, such as the laying of plastic film in plastic blind ditch, it can prevent water penetration down. Under capillary action, even slowly dry the crop roots, little water evaporates in the atmosphere, is the most water-saving irrigation methods. When too much rain and snow catchment, the system can be draining sense. 10. Roof garden roof garden cement surface drainage Xianpu plastic blind ditch material, holes and a layer of geotextile, geotextile and then capped with a layer of soil, you can plant flowers and trees in the above form a roof garden. After the case of rain filtered to retain particles penetrate the soil, drain away excess water harvesting, plants will not rot, the soil does not drain. 11. Plastic blind ditch material filter material sewage treatment specially formulated, can be acid and other chemical agents. Blind ditch plastic timber placed sewage tank can be used as filter material. Its specific gravity is lighter than water, and good characteristics and microbial affinity. Clearly than the gravel, etc. for medium to be superior.
