Hebei Cangzhou plastic blind ditch is of high quality and low price

The plastic blind trench is a frame structure formed by hot-melting modified polypropylene strands and overlapping each other, wrapped with a layer of geotextile. The clean water filtered by the geotextile enters the plastic blind trench and is discharged. The cross-section of the permeable pipe can be made into various shapes according to project needs, mainly rectangular and circular. List of plastic blind ditch models, specifications and performance indicators Product Features
The plastic blind ditch itself is made of many tough modified plastic wires that are fused together, and there is no possibility of being crushed or damaged. The cross-section porosity remains above % under pressure. Even if a large pressure is applied, there are always water-passing gaps, and there are still % pores and good recovery.
The average porosity of the surface of the plastic blind groove is %, which is much higher than other similar products. It can most effectively collect seepage water in the soil and drain it away in time.
The three-dimensional mesh combination of the filter membrane made of corrosion-resistant fiber and modified polyethylene has the advantage of never degrading in soil and water. The anti-aging formula can maintain permanent material unchanged. specialty. , The filter membrane of the plastic blind ditch can be selected according to different soil conditions to fully meet the needs of the project.
The plastic blind ditch has a light weight and is very convenient for on-site construction and installation, greatly speeding up the construction efficiency.
Scope of application
, highway, railway roadbed and shoulder drainage, retaining wall back drainage (vertical and horizontal drainage), tunnel, underground passage drainage, hillside, embankment and other slope drainage, sports fields, golf courses , Drainage of green areas such as airports and parks, drainage of coal dumps, landfills, composting sites and other sites, drainage cushions for decompression construction methods, underground irrigation and drainage systems for agriculture and gardening, roof garden drainage
, sewage Processed filter materials
Construction methods
Excavating trenches, filling gravel cushions, and laying filter membranes. , lay plastic blind ditch material and wrap the filter membrane around the blind ditch body. , Butt the plastic blind ditch or miter the plastic blind ditch. , backfill the blind trench with gravel and compact it.
The plastic blind ditch is a frame structure formed by hot-melting modified polypropylene yarn and overlapping each other, and is wrapped with a layer of geotextile. The muddy water is filtered through the outer geotextile into clean water, which enters the plastic blind ditch and is discharged. .
High compressive strength and good pressure resistance
Traditional blind ditch materials often have low compressive strength and are easily damaged under higher pressure, leading to drainage failure. The plastic blind ditch material is resistant to pressure
The plastic blind ditch material adopts an anti-aging formula and its performance is stable and has the characteristics of anti-ultraviolet, high temperature resistance, corrosion resistance, etc. Therefore, the plastic blind ditch material can remain underwater and in the soil for decades. The structure is stable and maintains drainage performance.
Surface porosity
Surface porosity refers to the ratio of the area of pores on the surface of the blind groove material to the surface area, generally expressed in %. It is an important performance that reflects the water absorption capacity of blind ditch materials. Generally speaking, the greater the surface porosity, the better the water absorption performance and the less likely it will be clogged. If the surface porosity is too small, it will easily become clogged and the water will not flow smoothly. The drainage effect is also poor. Under normal circumstances, the surface porosity should be %
Porosity
The void ratio of plastic blind trench refers to the ratio of the void volume of plastic blind trench material to the total volume. The void ratio is expressed in % due to the different arrangement density of fiber filaments. The void ratio of different plastic blind materials generally reaches %-%. The void ratio of plastic blind ditches can be calculated according to the following formula after a weighing test
The plastic blind ditch pipes produced by our company are also called undercover ditches, culverts, etc. The main function is to collect water seepage from the soil. It is used to reduce groundwater pressure and remove excess water to protect soil and buildings from damage due to seepage deformation. It is widely used in underground drainage projects in construction projects such as civil engineering, transportation, water conservancy, industrial and civil construction, mining, and environmental protection. With the development of polymer materials, plastic blind ditches were developed abroad in the 1970s. This product overcomes the shortcomings of traditional blind ditches and has the advantages of high porosity, strong pressure resistance, large drainage, and good durability. Therefore, it is generally welcomed by the engineering community and widely used. Our country began to develop a new generation of plastic blind trench materials in the 1980s and developed products for practical engineering applications in the early 1990s. Plastic blind ditch
