Drilled pile construction method
The invention discloses a drilled pile construction method, and relates to the field of constructional engineering. The drilled pile construction method comprises the following steps of S1, performingconstruction preparation; S2, burying a protective cylinder; S3, arranging a mud pool; S4, performing drilling machine drilling, namely, drilling by using a drilling machine; S5, performing primary hole cleaning, namely, cleaning a hole after the hole is drilled to a designed depth; S6, placing a steel reinforcement cage, namely, after the steel reinforcement cage passes acceptance inspection andwhen pre-operation is performed, splicing the steel reinforcement cage according to a designed size by an operator; and when the steel reinforcement cage is required to be placed, lifting the splicedsteel reinforcement cage to the position above a hole opening, and placing vertically and slowly; S7, placing a guide pipe; S8, performing secondary hole cleaning, after the guide pipe is placed, performing secondary hole cleaning through the guide pipe; S9, pouring underwater concrete; and S10, pulling up the protective cylinder. The trouble in performing butt welding on the steel reinforcementcage at the hole opening when the steel reinforcement cage is placed is avoided, so that the operation of placing the steel reinforcement cage is more convenient; and the construction period of the drilled pile is also shortened.
本发明公开了一种钻孔桩施工方法，涉及建筑工程领域，其包括以下步骤：S1，施工准备；S2，护筒埋设；S3，泥浆池设置；S4，钻机钻孔，通过钻机进行钻孔；S5，一次清孔，钻孔达到设计深度后，清孔；S6，下钢筋笼，钢筋笼验收合格后，在进行前序操作的同时，操作人员先将钢筋笼根据设计尺寸进行拼接；当需要下钢筋笼时，将拼接好后的钢筋笼吊装至孔口上方，垂直缓慢下放；S7，下放导管；S8，二次清孔，下好导管后，通过导管进行二次清孔；S9，灌注水下砼；S10，护筒提拔。通过提前将钢筋笼进行拼接，避免了在下钢筋笼时在孔口对钢筋笼进行对接焊接的麻烦，使得下钢筋笼的操作更加方便，也缩短了钻孔桩施工周期。
