Segment joint water leakage treatment method of shield tunnel in operation period

The invention discloses a segment joint water leakage treatment method of a shield tunnel in an operation period. The segment joint water leakage treatment method of the shield tunnel in the operationperiod takes blocking as the main purpose, combines the blocking with discharging, adjusts measures to local conditions, and comprehensively treats water leakage. In the tunnel maintenance process, the segment joint water leakage treatment method of the shield tunnel in the operation period adopts the comprehensive treatment construction method including the steps of filling segment joints with acrylate in a pouring mode for blocking water, using EPDM (ethylene propylene diene monomer) strips for filling the joints again to achieve water resistance and preforming water outlet channels in thejoints preformed in two sides of the tunnel for discharging water, and achieves good treatment effect. 本发明公开了一种运营期内的盾构隧道中管片接缝渗漏水处治方法，本发明以堵为主、堵排结合、因地制宜、综合处理渗漏水。在隧道养护过程中，采用了"丙烯酸盐注浆填充管片接缝堵水、三元乙丙橡胶条重新嵌缝防水、隧道两侧预留接缝预留出水通道排水"的综合处治施工方
