Underwater rotary excavating cast-in-place pile construction method
The invention discloses an underwater rotary excavating cast-in-place pile construction method which comprises the following steps: step 1, carrying out site arrangement, then carrying out drawing review, meanwhile, carrying out fixed-point axis checking, and then completing pile position lofting; secondly, a drilling machine is placed in place, and a drill bit of the drilling machine is manufactured; step 3, performing primary hole cleaning, and measuring the hole depth, the hole diameter and the gradient after hole cleaning is completed; fourthly, a reinforcement cage is manufactured, and the manufactured reinforcement cage is subjected to hanging welding, positioning and acceptance inspection; sixthly, after the guide pipe is installed, the slurry performance and sediment at the bottom of the hole are detected, and secondary hole cleaning is conducted after detection is completed; and 7, a waterproof plug is arranged, concrete is stirred, a concrete test block is manufactured, meanwhile, the elevation of the top face of the concrete is measured, then underwater concrete pouring is conducted to form a pile, then a pile casing is lifted, and a drilling machine is moved to complete pile construction. According to the construction method of the underwater rotary excavating cast-in-place pile, through the arrangement of the steps, pile position lofting is carried out before hole forming, and therefore the accuracy of the drilling position is well guaranteed.
本发明公开了一种水下旋挖灌注桩施工方法，包括如下步骤：步骤一，进行场地布置，然后进行图纸会审，同时进行定点轴线校核，之后完成桩位放样；步骤二，将钻机就位，制作钻机的钻头；步骤三，进行一次清孔，清孔完成后测量孔深、孔径以及倾斜度；步骤四，制作钢筋笼，将制作完成的钢筋笼吊焊并且定位验收；步骤六，在导管安装完成后，检测泥浆性能和孔底沉渣，并在检测完成后进行二次清孔；步骤七，设置隔水塞，搅拌混凝土，制作砼试块，同时测量砼顶面标高，后进行水下灌注砼成桩，之后提拔护筒，迁移钻机完成桩施工。本发明的水下旋挖灌注桩施工方法，通过上述步骤的设置，在成孔之前进行了桩位放样，如此很好的保证了钻孔位置的精确度。
