Construction method of lock catch steel pipe pile cofferdam
The invention provides a construction method of a lock catch steel pipe pile cofferdam, which comprises the following steps: step 1, planning and determining a construction position of the cofferdam; step 2, along the construction position of the cofferdam, a plurality of first backfill holes are constructed at intervals by using a rotary drilling machine and a steel casing, and a second backfill hole is constructed between every two adjacent first backfill holes; the adjacent first backfill holes and second backfill holes are crossed and overlapped; and 3, lock catch steel pipe pile inserting and driving construction is conducted on the first backfill holes and/or the second backfill holes along the construction position of the cofferdam, and a circle of lock catch steel pipe pile cofferdam is formed. According to the method, the first backfill hole and the second backfill hole are alternately constructed by using the rotary drilling machine through the steel casing by adopting a step-by-step replacement method, and then the lock catch steel pipe pile inserting and driving construction is performed on the backfill holes, so that the holes can be safely and efficiently formed, the lock catch steel pipe pile can be smoothly inserted and driven into the complex stratum, the operation is simple, and the popularization is convenient.
本发明提供了一种锁扣钢管桩围堰的施工方法，包括以下步骤，步骤1、规划确定出围堰的施工位置；步骤2、沿着围堰的施工位置，使用旋挖机利用钢护筒间隔施工若干个第一回填孔，相邻两个第一回填孔之间施工第二回填孔；相邻的所述第一回填孔和所述第二回填孔形成交叉重叠；步骤3、在所述第一回填孔上和/或所述第二回填孔上，沿着围堰的施工位置，进行锁扣钢管桩插打施工，形成一圈锁扣钢管桩围堰。本申请首先使用旋挖机利用钢护筒采用分步置换的方法，进行第一回填孔和第二回填孔交替施工，然后在回填孔上进行锁扣钢管桩插打施工，能够安全高效引孔成形，顺利将锁扣钢管桩插打入复杂地层，操作简单，便于推广。
