Tunnel temporary levee construction method
The invention discloses a tunnel temporary levee construction method. Comprising the following construction sequence: construction preparation and lofting, retaining wall dismantling and cofferdam filling (including cofferdam underground block stone removal) Temporary levee construction obstacle removal, temporary levee construction, foundation pit one-time drainage, cofferdam removal of retaining wall in the temporary levee, regular drainage facility in the foundation pit, original levee excavation, tunnel construction, levee filling and retaining wall recovery, safety monitoring facility construction, secondary cofferdam construction, retaining wall lower plate pile groove grouting treatment at the temporary levee position, and foundation pit construction. The retaining wall at the temporary levee is recovered; the temporary levee is dismantled; according to the tunnel temporary levee construction method disclosed by the invention, the enclosed temporary levee has the advantages of leakage prevention and high safety; wide popularization and application are facilitated.
本发明公开了一种隧道临时大堤施工方法，包括以下施工顺序：施工准备及放样→挡墙拆除围堰填筑(含围堰地下块石清除)→临时大堤施工障碍物清除→临时大堤施工→基坑一次性排水→临时大堤内挡墙拆除围堰→基坑内经常性排水设施→原大堤开挖→隧道施工→大堤填筑及挡墙恢复→安全监测设施→二次围堰→临时大堤处挡墙下板桩槽灌浆处理→临时大堤处挡墙恢复→临时大堤拆除；本发明公开的隧道临时大堤施工方法，围建的临时大堤具有防渗漏，安全性高的优点；有利于广泛推广应用。
