Selection of Plastic Drain Pipe based on Performance Requirements and New Trenchless Technology

Based on introducing the types of plastic drain pipes, selection of plastic drain pipes were analyzed from performance requirements such as stiffness and strength,leak tightness,pipe laying and combination property.Several new trenchless technologies for plastic drain pipe were contrastively analyzed, including fitlining method,draw pipe method,horizontal directional drilling method,and the advantages and disadvantages of various methods are evaluated.
