Construction and quality requirement of plastic drainage pipe;

Because the traditional concretes outdoor drainage pipes have many shortcomings in the application process,the main research goal of this article is that the plastic discharge pipe replace the concretes discharge pipe to avoid concrete pipe\'s many questions inapplication.

The article elaborated the Jin city urban district terrain and the draining water pipe network present situation, has analyzed several questions which in the plastic discharge pipe construction must pay attention, as well as plastic discharge pipe in Jin city draining water pipe network\'s application prospect.

Technological requirements and performance of plastic draining materials in common use are introduced in this paper and the stateoftheart of plastic drainage technology applied in geoenvironmental engineering in China is reviewed.

Experimental research of maximum allowable fullness ratio (α) of plastic drainage stack;

Application Enforcement of the plastic drainage pipes had to stablish the theory for estimating of the maximum discharge capacity of the plastic drainage stack in building and the core issue of the theory was to determining of the maximum allowable fullness ratio of the plastic stack.

In the recent year, plastic drainage piping widely applies in municipal drainage piping project.
