Site drainage settlement
Because of the need for four sloping but uneven ground, surface waves and funnel type;
In the design and construction of complex slope;
because the pipeline requires a certain depth, thus a large amount of excavation;
High risk - poor drainage, water area;
In the pipeline has been clogged and cause system failure;
In the pipeline system with high maintenance costs;
There may be other underground pipeline system conflict
Linear drainage:
Linear - simple uniform appearance;
In the linear continuous water drainage, higher efficiency;
simple and easy to find the slope construction;
convenient installation, shallow depth excavation;
can effectively reduce the buried in the pipeline construction;
because of the linear drainage system of water collection Yubi exposure and the ground, easy cleaning and maintenance
