Lock catch steel pipe pile cofferdam guide hole construction method
The invention relates to a lock catch steel pipe pile cofferdam guide hole construction method which comprises the following steps: firstly, constructing two pile holes at an interval, respectively arranging wall protection steel casings in the two pile holes, and then constructing a pile hole engaged with the two pile holes between the two spaced pile holes; and the construction process is circulated, and meanwhile, the lock hole steel pipe piles are inserted into the completed pile holes until all the steel pipe piles of the lock catch steel pipe pile cofferdam are inserted and driven. The retaining wall steel casing can support the pile hole, effectively prevents hole collapse caused by insufficient compactness of backfilled clay during hole guiding, can guide excavation of the secant pile hole, and ensures the perpendicularity of the pile hole.
本发明涉及一种锁扣钢管桩围堰引孔施工方法，先间隔施工两个桩孔，并在两桩孔内分别设置护壁钢护筒，然后在两个间隔桩孔之间施工一与两桩孔咬合的桩孔；循环上述施工过程，同时在已完成桩孔内插打锁孔钢管桩，直至完成锁扣钢管桩围堰所有钢管桩插打。护壁钢护筒能对桩孔起支护作用，有效防止引孔时因回填黏土密实度不够而引起塌孔，还能对咬合桩孔开挖起导向作用，保证桩孔垂直度。
