New products for plastic blind trenches in Chengdu, Sichuan

The plastic blind ditch is composed of a plastic core wrapped with filter cloth. The plastic core is made of thermoplastic synthetic resin as the main raw material, which has been modified and extruded into thin plastic filaments through a nozzle in a hot-melt state. The extruded plastic filaments are then welded to the nodes through a molding device to form a three-dimensional network. shape structure. At present, plastic cores have various structural forms such as rectangular, hollow matrix, circular hollow circle, etc. This material overcomes the shortcomings of traditional blind ditches, has high surface porosity, good water collection, good void ratio, large drainage, good pressure resistance, good flexibility, good adaptability to soil deformation, good durability, light weight, convenient construction, and greatly reduces the labor intensity of workers. Due to its high construction efficiency, it is generally welcomed by engineering bureaus and has been widely used.
Scope of application of plastic blind trenches) Reinforced drainage of roads and railway roadbed shoulders) Drainage of tunnels, subway underground passages, underground freight yards) Soil and water conservation of hillside and slope development) Vertical and horizontal drainage of various retaining walls ) Drainage of slippery floors) Drainage of ash piles of thermal power plants. Drainage of landfill projects) Drainage of resting green spaces such as sports fields, golf courses, baseball fields, football fields and parks) Drainage of roof gardens and flower beds) Drainage of building foundation projects) Underground irrigation and drainage systems of agriculture and gardening) Drainage systems of low-lying wet lands. Drainage plastic blind ditch materials for land preparation projects are internationally known as composite geotechnical drainage bodies (D), also known as three-dimensional drainage panels and drainage culvert materials for civil engineering. It is a three-dimensional porous material made by heating and melting thermoplastic synthetic resin, extruding fiber filaments through a nozzle, stacking them together, and fusing their joint points. The products are available in various specifications such as circular and rectangular cross-sections. Products with different properties such as high temperature resistance, flame retardant, strong acid and alkali resistance, high elasticity, and high hardness can be produced according to customer orders with different formulas.
Characteristics of plastic blind ditch
The fibers of plastic blind ditch are the left and right filaments that are sintered and sintered to form a three-dimensional network. The principle is the same as the truss principle of steel structures. The surface opening coverage is -% which is twice that of perforated tubes and - times that of resin grid tubes. The surface water absorption rate is extremely high.
. Since it is a three-dimensional structure, its void ratio is -%, and the space is the same as the management. It is lightweight and has more than three times stronger compression resistance than the resin of the tube structure. Therefore, even if it is compressed due to overload, the residual void is up to 100% because it is a three-dimensional structure. % or above, there is no problem of water leakage, and there is no need to consider that it will be crushed by earth pressure.
, Compressive strength, its compression rate is lower than % under high pressure.
Added with anti-aging agent, it is durable and can ensure stability even if it is placed in underwater soil and other places for decades.
It is compression-resistant and flexible and can be used for construction in curves such as curves. It is very light and can be backfilled with a bulldozer if the backfill depth is at the left or right.
. Due to the above characteristics, various problems that occurred in traditional blind ditches in the past, such as uneven settlement or partial blockage due to overloading, which are crushed, resulting in no gaps and functional interruptions, can be solved by plastic blind ditch materials.
Since it adopts hot melt molding without using adhesive, it will not cause collapse due to aging and peeling of the adhesive.
