非开挖电力管线下穿河道的问题及防护措施

结合电力排管配套供电工程的相关涉河论证经验，对电力管线非开挖定向钻进技术下穿河道的2种典型断面进行分析，提出电力管建设项目穿河过程中存在的问题和可能对河道堤防结构造成的安全隐患，并对河道堤防结构防护措施提出建议。对维护河道堤防安全，保持河势稳定和河道行洪、输水通畅，保障城市防汛安全均有着重要意义。

Problems and Protective Measures of Trenchless Power Pipeline Undercrossing Rivers

Combined with the experience of river-related demonstration of the power supply project supporting the power pipe, two typical cross-sections of power pipeline trenchless directional drilling technology undercrossing the river are analyzed and discussed. The problems existing in the process of power pipeline projects undercrossing river and the safety hazards to the river embankment structure are proposed. The suggestions for the protection measures of the river embankment structure are put forward. It is of great significance to maintain the safety of river embankments, maintain the stability of river regime, ensure the smooth flow of flood discharge and water conveyance, and ensure the safety of urban flood control.
