In many sewer excavation project which do not permit digging to lay out waste pipe or transformation of the road widening,it usually use the technology of oriented methods which have advanced navigation systems,to economicly,rapidly,accurately complete the laying of pipe task.

But the project of sealing the waste pipe around is its successfully up?to?date applicational achievement.

Taking the installation of the sewage pipeline in Bigui Road of Shunde District in Foshan City Guangdong Province as an example, the article introduces its installing process.

A part of reinforced concrete sewage pipes under the middle Su-Hong road in Suzhou Sino-Singapore Industrial Park ruptured and the ground surface sank due to the softening of the soil below, soil liquefaction and sandy drifting resulting from joint leakage.

Optimum research on plot sewage pipe network plan based on fuzzy comprehensive evaluation;

Application of improved single parent genetic algorithm for optimal design of the layout of sewage pipe network;

The simulated calculation of nodal flow in sewage pipe network system is the essential work for the planning design and operation management of the urban sewage pipe network system.

Application of Genetic Algorithm in Optimization of Sewage Networks;

In view of the existing problems of the genetic algorithms,a model of optimized sewage network by using particle swarm optimization(PSO) was proposed.
