特点
Characteristic
◆ 排水效率受制因素较多、易造成地面积水；
◆ the drainage efficiency is subject to many factors, which is easy to cause ground water accumulation;
◆ 由于需要四面找坡导致地面不平整、地表呈现波浪 或漏斗形状；
◆ due to the need for slope making on all sides, the ground surface is uneven, showing wave or funnel shape;
◆ 坡度设计和施工比较复杂；
◆ the slope design and construction are complex;
◆ 由于管道需要一定埋深，因此施工开挖量较大；
◆ because the pipeline needs to be buried to a certain depth, the excavation volume is large;
◆ 管道易于堵塞并造成系统失效；
◆ the pipeline is easy to block and cause system failure;
◆ 管道系统维护成本高；
High maintenance cost of pipeline system;
◆ 有可能与其他埋地管线有冲突。
◆ there may be conflicts with other buried pipelines.
