摘　　要：地下综合管廊作为全地下结构,受限于传统施工工艺,后期渗漏问题较严重。结合天津市宝坻区西环路地下综合管廊二期工程,对钢板止水带及橡胶止水带精确定位工作原理与施工技术进行研究。研究结果表明,设置专用固定装置后,有效解决了止水带定位、加固、焊接损伤问题,避免安全隐患,降低施工成本。As an all-underground structure, the underground utility tunnel is limited by traditional construction techniques, the later leakage problems are more serious. Combined with the second phase project of the underground utility tunnel in Baodi District, Tianjin, the work principle and construction technology of the precise positioning of the steel waterstop and rubber waterstop of the underground utility tunnel are studied. The research results show that this technology effectively solves the problem of waterstop positioning, reinforcement and welding damage, also effectively eliminates potential safety hazards and reduces construction costs.
