非开挖施工管道进出洞口的细节设计

On Detailed Design of the Pass in and out Openings of Non-excavation Construction Pipeline

结合非开挖管道工程中常见进出口的问题,提出了在设计环节中应采取利用圆形橡胶板止水,并用钢压板固定。通过实例,分别对顶管施工工艺和牵引管施工工艺从设计、施工及相应规范方面作了简介,尤其对封堵细节作了具体介绍。

Combined with the common pass in and out opening problems occurred in non-excavation pipeline projects, the round rubber sheet and steel pressure plate should be used in the design stage. Through the practice, the jacking pipeline and tractive pipe construction techniques were introduced from design, construction and standards, especially, the plugging details were emphasized.
