High-bearing-capacity building piling method
The invention relates to a high-bearing-capacity building piling method. The method comprises the steps that firstly, a pipe pile is prefabricated: a pile tip is welded to a pile body, the surface of the pile tip is coated with an anti-rust coating, and the surface of the pile body is coated with an epoxy asphalt coating; secondly, installation is conducted: the pipe pile is vertically hoisted and fixed to a retaining seat at the lower end of a pile hammer, a positioning support is assembled on the ground, and the pile tip at the lower end of the pile body vertically penetrates through a positioning support to abut against the ground; thirdly, pile sinking is conducted: the pile hammer continuously falls down to hit the upper end of the retaining seat, and the retaining seat drives the pile body to gradually sink into the ground; and fourthly, pile splicing is conducted: another pile body with the same diameter is welded and fixed to the upper end of the pile body, and the axis deviation of the two pile bodies does not exceed 2 mm; fifthly, pile feeding is conducted: the top of the upper half pile body at the lower end of the retaining seat, and the upper half pile body is sent into the ground through the pile hammer; and sixthly, pile cutting is conducted. The method has the advantages that large-size pipe pile construction can be achieved, and the construction efficiency and the construction accuracy are improved.
本申请涉及一种高承载力建筑打桩方法，包括步骤一，预制管桩，将桩尖焊接于桩体上，在桩尖表面涂刷防锈涂层，在桩体表面涂刷环氧沥青涂层；步骤二，安装，将管桩竖直吊起并将管桩与桩锤下端的保持座固定，在地面组装定位支架，使得桩体下端的桩尖竖直穿过定位支架抵接在地面上；步骤三，沉桩，将桩锤持续落下下砸至保持座上端，使得保持座带动桩体逐渐沉入地面；步骤四，接桩，在桩体的上端焊接固定另一根同直径的桩体，两根桩体的轴线偏差不超过2mm；步骤五；送桩，将上半部分桩体的顶部固定在保持座下端，通过桩锤送入地面；步骤六，截桩。本申请具有可对大体积管桩施工，加快施工效率和施工准确度等特点。
