    Plastic inspection Wells,Plastic check well divided into community with check well and municipal use inspection Wells, should be according to the installation position of inspection well in engineering application, determine the corresponding inspection shaft specifications.A well,Inspection shaft should be set 1. Sewage flow slot, chute design specific requirements: slotted sewage check well flow should be 0.85 times with great diameter is flat, the flow of rainwater and confluence system inspection Wells slotted with 0.5 times fill pipe diameter is flat. Chute width at the top of the appropriate maintenance requirements.2. The rain check well want to slime room, various places have different practices, some area inside the village inspection Wells are not heavy mud chamber; In some areas...

    HDPE double-wall corrugated pipe is high density polyethylene as the main raw material, through the two method preparation and molding process. The first step has been produced by the extruder complete shrinkage, density, high strength type "T" slab; The third use of precast slab on the pipe forming machine winding and welding into pipe lining, at the same time, galvanized steel strip rolling into U steel belt into plate belt between the slot, and on the outside of the strip cladding PE become a new gangsu composite material of the outer wall of pipeline.HDPE double-wall corrugated pipe and compared with material solid wall pipe, can save nearly half of all raw materials, corrugated pipe is simple and reliable installation, so the HDPE double-wall corrugated pipe construction cos...
