Zhangjiakou crushed stone plastic blind trench manufacturer's price

The plastic blind channel is composed of a plastic core tube wrapped with a filter fabric assembly. The plastic core tube is primarily made of thermoplastic synthetic resin, which is modified and then extruded into fine plastic filaments in a molten state through a nozzle. These filaments are then fused together at junctions by a molding device.Section 4 indicates the product's structure. When marked as "K," the product is hollow (single-hole). Marked as "D," it indicates a porous product; the number before "D" denotes the number of holes. For example, a circular plastic drainage pipe has an outer diameter of 100mm and is single-hole, hence it is designated as SMY100K. A rectangular plastic drainage pipe has a cross-sectional width of 150mm and a thickness of 50mm, also with a single hole, and is referred to as SMJ150 x 50K. It forms a three-dimensional mesh structure.Plastic core bodies come in various structures such as rectangular, hollow matrix, and circular hollow circular shapes. This material overcomes the shortcomings of traditional blind gutters, featuring high surface porosity, good water collection, high void ratio, excellent drainage, strong compressive resistance, good pressure resistance, flexibility, adaptability to soil deformation, durability, light weight, ease of construction, and significantly reduced labor intensity for workers, resulting in high construction efficiency. Therefore, it is widely welcomed by engineering departments and has been extensively applied. The naming of plastic drainage blind gutters is divided into four parts.Part is coded as SM; the second part indicates the shape of the trench drain, Y for round and J for rectangular; the third part shows the outer dimensions of the trench drain, where for round it denotes the outer diameter of the core (mm), and for rectangular, it represents the cross-sectional dimensions (width x thickness, mm).
