Method for improving water stopping effect of Larsen steel sheet pile
The invention provides a method for improving the water stopping effect of a Larsen steel sheet pile, and belongs to the technical field of building construction technologies. The method for improving the water stopping effect of the Larsen steel sheet pile comprises the following steps that S1, when a screw rod drills a guide hole, when the guide hole is pre-dug, a drill bit at the top end of a drill rod grinds hard geology such as pebbles and rocks to form drilling slag, and the drilling slag in the hole is brought out of the bottom of the hole through rotation of spiral fan blades of the drill rod and then discharged out of the hole through slag outlet holes in the two sides of a sleeve of the drill rod; a hole channel is formed after the drilling slag is discharged; s2, backfilling clay to make slurry; s3, clay and drilling slag are backfilled; s4, reversing and compacting the drill rod; and S5, the Larsen steel sheet piles are pressed in. The water stopping effect of the Larsen steel sheet pile in the strong water-rich, pebble and rock hard geology is improved; the construction method is wide in material source, local materials can be used, the cost is saved, and the best effect is achieved with the minimum investment; the functions of the static pressure pile planting machine are fully utilized, extra construction equipment is not needed, the construction method is simple, and operation is easy and convenient.
本发明提供了一种提高拉森钢板桩止水效果的方法，属于建筑施工技术技术领域。该一种提高拉森钢板桩止水效果的方法：包括如下步骤：S1：螺旋杆钻进引孔，预掘引孔时，钻杆顶端的钻头将卵石、岩石等坚硬地质磨碎形成钻渣，孔内钻渣通过钻杆螺旋扇叶旋转被带出孔底，再通过钻杆套筒两侧的出渣孔排出孔外，排出钻渣后形成一个孔道；S2：回填黏土造浆；S3：回填黏土与钻渣；S4：钻杆反转压实；S5：压入拉森钢板桩。本发明提高了强富水、卵石、岩石坚硬地质拉森钢板桩的止水效果；施工方法材料广泛，可就地取材，节约成本，以最小的投入来实现最好的效果；充分利用静压植桩机自身的功能，无需额外的施工机具配合，施工方法简单，操作简便。
