Safe construction method of shield cutter head repair space
The invention discloses a safe construction method for a shield cutter head repair space, which provides a safe, quick and economical repair space for repairing a shield cutter head of a large-diameter shield tunnel. The method comprises the following steps of finding a proper repair position, precipitation and pile foundation construction, pile grinding to a hollow pile position, construction safety condition confirmation and tool replacement and cutter head repairing. According to the safe construction method, the method of direct piling and then repairing is adopted, the construction process is simple, the construction period is short, three hollow piles are arranged in each row, two hollow piles is used for welding and one hollow pile is used for exhausting air and smoke, the safety ishigh, and the cost is low.
本发明公开了一种盾构刀盘修复空间的安全构建方法，为大直径盾构隧道盾构刀盘修复提供安全、快速、经济的修复空间，其步骤是：找到合适的修复位置→降水、桩基施工→磨桩推进至空心桩位置→施工安全条件确认→刀具更换及刀盘修复，本发明采取直接打桩，然后修复的方法，施工工艺简单，施工工期短，每排设置3个空心桩，两个焊接1个排风排烟，安全性高，成本低。
