(Summary description)Drainage pipes are mainly responsible for drainage of rainwater, sewage, irrigation and drainage of farmland. Drainage pipes are divided into concrete pipes (CP) and reinforced concrete pipes (RCP). Drainage pipe specifications include pipe inner diameter DO (100mm-3000mm), length LO (30mm-200mm), pressure index, grade Ⅰ, grade Ⅱ and grade Ⅲ. The caliber is divided into: flat mouth, tongue and socket, socket, double socket, steel socket. Production of reinforced concrete drainage pipe equipment: mixing system, pipe mold (flat mouth, tongue and socket, double socket, steel socket), forming equipment (centrifuge, suspension roller, vertical axial extrusion molding machine, vertical Radial extrusion molding machine, core mold vibration hydraulic molding machine, vertical radial extrusion molding machine, core mold vibration hydraulic molding machine, vibration molding device), feeder, steel plate skeleton roll welding machine, hydraulic press, external pressure Machine waiting. The drainage pipe is a new type of permeable and drainage plastic pipe with corrugated appearance formed by adding other additives to high density polyethylene (HDPE). The permeable corrugated pipe is perforated in the groove, and the outer circumference of the pipe is covered with acupuncture geotextile. Processed. According to the type of bellows, it can be divided into single-wall water-permeable bellows and double-wall water-permeable bellows. Because the pipe hole of this product is in the wave trough and is elongated, it effectively overcomes the drawbacks of flat round hole products that are easy to be blocked and affect the drainage effect. According to different drainage requirements, the size of the pipe hole can be 10mm×1mm-30mm ×3mm, and can be evenly distributed in the range of 360 degrees, 270 degrees, 180 degrees, 90 degrees, etc., widely used in roads, railway subgrades, subway projects, waste landfills, tunnels, green belts, sports fields and partial moisture content High-induced slope protection and other drainage fields, as well as underground irrigation and drainage systems for agriculture and horticulture. Together with soft permeable pipes and plastic blind ditch, it has become the three main products in civil engineering construction (water seepage and drainage) in my country. Depending on the drainage pressure, the municipal drainage network can choose double-arm corrugated pipes and straight wall pipes. Straight-wall pipes have strong pressure bearing capacity and can be used as special pipes for large drainage and sewage pipe networks.
