    摘要: A plastic drain pipe for drainage includes a first end, a second end, and a pipe sub-section between the first end and the second end. The pipe sub-section includes a collapsible section of corrugated pipe, a first non-collapsible section of corrugated pipe, and a second non-collapsible section of corrugated pipe. The collapsible section of corrugated pipe has a first joining area and a second joining area. The first non-collapsible section of corrugated pipe is connected to the collapsible section of corrugated pipe at the first joining area, and the second non-collapsible section of corrugated pipe is connected to the collapsible section of corrugated pipe at the second joining area. An outermost diameter of the collapsible section of corrugated pipe is approximately the same as an outermost diameter of the first non-collapsible section of corrugated pipe and an outermost diameter of the second non-collapsible section of corrugated pipe.
