Pile pulling method for box type steel sheet pile
The invention provides a box-type steel sheet pile pulling method, which comprises the following steps that site leveling is realized by paving a heavy-load road; a groove used for the box type steel sheet pile pulling construction position is excavated through an excavator, and water in the groove is drained after the groove is excavated; a plurality of water jet cutters with high-pressure water pipes are additionally arranged on the periphery of the to-be-pulled pile and the connecting positions of the to-be-pulled pile and other piles; and meanwhile, pile pulling is conducted, high-pressure water injection is conducted on a high-pressure water pipe connected with the water jet cutter, and pile pulling is completed while friction resistance of the periphery of the to-be-pulled pile is reduced. According to the method, pile pulling, water injection and pile pulling are conducted at the same time, water injection and pile pulling are conducted at the same time, vibration force generated during pile pulling can generate a shear face on the side face of the pile, high-pressure water penetrates into the surface of the pile, and therefore the pile pulling resistance of the pile is reduced; and meanwhile, a high-pressure water jetting method is used as a pile sinking resistance reduction measure to perform resistance reduction again.
本发明提供了一种箱型钢板桩的拔桩方法，包括以下步骤，利用铺设重载道路实现场地整平；利用挖机开挖用于箱型钢板桩拔桩施工处的沟槽，并在沟槽开挖完成后排出沟内的水；分别在待拔桩的外周，以及待拔桩与其它桩的连接处，增加若干个带有高压水管的水刀；同时进行拔桩以及对水刀连接的高压水管进行高压注水，在减少待拔桩外周的摩擦阻力的同时完成拔桩。本发明中的拔桩，注水和拔桩同时进行，注水和拔桩同时施工可以在拔桩时产生的振动力在桩侧面产生剪切面，让高压水深入桩的表面从而减少桩的拔桩阻力；同时，利用高压射水法作为沉桩减阻措施进行再次的减阻。
