Fenghua cul common specifications 50MM Fenghua blind tube, 80MM Fenghua blind tube, 100MM Fenghua blind tube, 150MM Fenghua blind tube, 200MM Fenghua blind tube, special specifications can be customized. The advantage of blind pipe: (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) the average hole surface of the plastic blind ditch. up to 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, aging, UV resistance, 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, to avoid overloading. 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 in other types of blind ditch. overall costs low. Engineering Application blind tube: (1), roof drainage (2), playgrounds, golf courses, airports, parks and other green drainage (3), retaining wall on the back of drainage (vertical, horizontal drainage) (4), agriculture, Gardening of underground irrigation and drainage systems (5), slopes, embankments and other slope drainage (6), tunnels, underground drainage channel (7), highway, railway embankment and shoulder drainage (8), soft foundation treatment horizontal drainage pipe major blind Specifications: diameter Φ80mm, Φ100mm, Φ150mm, Φ200mm, special specifications can be customized. Blind tube Features 1, constituent fibers plastic blind ditch about 2mm yarn, mutual contacts melt form type, a three-dimensional mesh body, the same principle and the steel truss creation. Surface shelter openings 95-97%, which is more than five times the bore tube is 3-4 times the resin mesh tube surface, high water absorption. 2, since the three-dimensional structure, a porosity of 80-95%, and constituting the space with the same light management, compression performance than the resin pipe structure of more than 10 times stronger, and therefore, even if the pressure due to overload, it is a three-dimensional structure, so the residual gap of more than 50% water barrier is no problem, no need to consider earth pressure will be crushed. 3, compressive strength, at 250KPa pressure, the compression ratio is less than 10%. 4, plus anti-aging agent, durable in water, soil, etc. into the home for decades but also to ensure stability. 5, compression and flexible for curved corners and other construction site can be very light, if the backfill depth of about 10cm, but also with a bulldozer backfilling. 6, due to the above characteristics, so the past, the traditional blind ditch various problems, such as uneven settlement or partial occlusion caused by overloading, resulting in voids being crushed no cause functional disruptions can solve by plastic blind ditch material . 7, the use of hot melt molding manner without using a binder, the binder aging and it will not cause peeling of collapse. Blind drainage pipe known it? Blind drainage pipe, also known as blind ditch drainage, mainly in synthetic fibers, plastics and synthetic rubber and other raw materials, made by a different process for various types of geotechnical multifunction products. The material hydrophobic, resistance, has a very high surface water seepage through internal capacity and capability; and has excellent compressive deformation capability and adaptability; has excellent chemical inertness, geotechnical engineering use to maintain long life; light weight, convenient and easy to cut, construction and installation. The main role of applications is a row of soil water seepage, to reduce groundwater pressure, remove excess moisture, protecting soil and buildings will not produce seepage deformation and damage. Widely used in underground drainage works civil collection, transportation, water conservancy, civil miners, environmental protection and other construction projects. Gardening blind drainage pipe and general engineering blind tube is slightly different in the material, the use of natural volcanic rock suitable for plant growth and other lightweight, good permeability of the filter material as a filler, in solving the drainage problems at the same time the green base plate , but also solve the general engineering cul use that often appear in lawn color problem.
