开槽埋管（承插管、企口管）作业指导书
    1特点
    1．1管道接口防渗漏性能好
钢筋混凝土承插管其接口的水密机理主要依靠接口之间的“O”型橡胶圈的弹性压缩，钢筋混凝土企口管的接口之间的止水材料是采用了目前世界上较先进的拉密尔橡胶止水圈（见图），具有良好的防渗漏性能。
 
    1．2施工工艺简单
    由于钢筋混凝土承插管及企口配用橡胶圈的接口形式均为柔性接口形式，允许在接口部位可发生微量的转角或微量的水平位移
Slot Buried (Cheng intubation, I stand pipe) Operating Instructions
    1 Features
    1.1 channel interface, good performance against leakage
Reinforced concrete bearing tube watertight mechanism of its interfaces rely on interfaces between the "O" ring rubber elastic compression, reinforced concrete pipe interface I stand between the sealing material is used the world's more advanced Rami Seoul rubber sealing ring (see photo), has good anti-leakage performance.
 
    1.2 The construction process is simple
    As the reinforced concrete commitments intubation and I stand with rubber ring with a flexible interface, the interface forms are forms that allow trace may occur in the interface part of the corner or the trace of horizontal displacement
