Synchronous follow-up hole-forming construction process of pile casing structure for pile foundation construction
The invention relates to a synchronous follow-up hole-forming construction process of a pile casing structure for pile foundation construction. The synchronous follow-up hole-forming construction process comprises the following steps that S1, site leveling is conducted on a construction site; s2, pile position lofting is conducted, and cross-shaped fender piles are arranged; s3, the pile foundation casing is connected with a drill bit of a drilling machine, the drill bit of the drilling machine is moved to the position above the pile position, first-time drilling is conducted vertically downwards, and a construction hole is drilled in the pile position; s4, the drill bit of the drilling machine is pulled away from the pile foundation pile casing, and the pile foundation pile casing is left in the construction hole; s5, the drill bit of the drilling machine is moved into the construction hole, and drilling is conducted downwards for the second time; s6, the drill bit of the drilling machine is moved out, hole bottom drilling slag and slurry are taken out, and slurry on the inner wall of the pile foundation casing is removed; s7, a reinforcement cage is put into the construction hole; s8, the guide pipe is inserted into the construction hole; and S9, concrete is poured into the guide pipe, and the pile foundation pile casing is pulled out of the construction hole. The method has the effect of improving the construction quality of pile foundation construction drilling.
本申请涉及一种桩基施工用护筒结构同步跟进成孔施工工艺，包括以下步骤：S1.在施工场地进行场地平整；S2.桩位放样，设置十字护桩；S3.将桩基护筒与钻机钻头相连接，将钻机钻头移动到桩位上方，垂直向下进行第一次钻孔，在桩位处钻出施工孔；S4.将钻机钻头抽离桩基护筒，令桩基护筒留在施工孔中；S5.将钻机钻头移入施工孔内，向下进行第二次钻孔；S6.移出钻机钻头，取出孔底钻渣及泥浆，除去桩基护筒内壁的泥浆；S7.向施工孔放入钢筋笼；S8.将导管插入施工孔中；S9.向导管浇注混凝土，将桩基护筒拔出施工孔。本申请具有提高桩基施工钻孔的施工质量的效果。
