Construction method for enabling underground comprehensive pipe gallery to pass through river channel
The invention provides a method for enabling an underground comprehensive pipe gallery to pass through a river channel, and belongs to the technical field of underground pipe gallery construction. Themethod comprises the following steps that construction information is obtained, and the positions of working wells on the two sides of a river channel are determined; reinforcing, waterproofing and excavation construction are conducted on all the working wells; a pipe pushing platform is set in each working well, and debugging is performed on a pipe pushing machine; excavating is performed in thepipe roofing, and internal supports are performed in the excavated pipe roofing; and construction of the pipe gallery main body is gradually conducted in the pipe roofing, the inner supports are sequentially dismantled, and finally the complete underground comprehensive pipe gallery is formed. According to the method, excavation and rerouting of the river channel are avoided, the ecological environment is favorably protected, and meanwhile the risk of cofferdam collapse caused by reduction of the flood drainage capacity is avoided; the method is simple in construction, secondary flow guidingand inverse construction is not needed, the construction period is greatly shortened, and the construction cost is correspondingly reduced; and the adopted pipe roofing underground excavation is deeper in construction depth, the pipeline group can be avoided in the city, and higher safety is achieved.
本申请提供一种地下综合管廊穿越河道的方法，属于地下管廊施工技术领域。该方法包括：获取施工信息，确认河道两侧的各工作井位置；对各工作井进行加固、防水以及开挖施工；在各工作井中设置顶管平台以及顶管机的调试；在管幕内进行开挖，并对开挖后的管幕进行内支撑；在管幕内逐步进行管廊主体的施工，并依次拆除内支撑，最终形成完整的地下综合管廊。该方法避免了对河道的挖掘与改道，有利于保护生态环境，同时避免了到排洪能力降低带来的围堰塌陷的风险；该方法施工简单，不需要进行二次的导流倒边施工，大大缩短了工期，相应的减少施工成本；采用的管幕暗挖，施工深度较深，在城市中能够避开管线群，更加安全。
