The pipe body has low impermeability and short service life;
2、 预应力混凝土管在其成型后修补率很高， 维修维护成本大， 管体自身重量较 重， 直接影响现场施工的安装速度， 增加了施工成本； 2. The pre-stressed concrete pipe has a high repair rate after molding, the maintenance and maintenance cost is large, and the weight of the pipe body is heavier, which directly affects the installation speed of the site construction and increases the construction cost;
3、 其他接口形式的混凝土排水管， 管体重量大， 接口形式多为钢性的， 所以在 软土层施工时很容易产生地基下沉现象， 造成管材接口开裂及所输送的污水及其它介 质外泄， 因此施工人员为避免地基下沉需要对地基进行预前处理， 这会使施工的成本 大幅提高， 也增加 施工的难度。 3.
