Cast-in-situ bored pile construction method
The invention provides a cast-in-situ bored pile construction method. The cast-in-situ bored pile construction method comprises the following steps that S1, pile hole positioning is conducted, specifically, after the plane position is determined, measurement is carried out according to an installation drawing, and the pile hole position is marked for use in the next step of construction; S2, site leveling is conducted, specifically, site sundries are cleared, and tamping and leveling are conducted; S3, pile casing burying is conducted, specifically, a steel plate is rolled and welded into a pile casing, the height of the pile casing is larger than or equal to 1.0m, and the pile casing and a pile hole are correspondingly buried in the ground; S4, drilling and hole forming are conducted, specifically, a drilling machine is adopted for forming holes in the pile hole position and clearing the holes; S5, reinforcement cage placement is conducted, specifically, a reinforcement cage is hoisted and placed into the pile hole; and S6, concrete pouring is conducted, specifically, concrete is poured into the pile hole. The cast-in-situ bored pile construction method is simple, the pile position of a drilled hole can be positioned by burying the pile casing, deviation of the drilled hole is avoided, the drilling precision is ensured, the pile casing is made by rolling and welding the steel plate, the equipment cost expenditure is reduced, residues in the drilled hole are cleared in time after drilling, and the bonding strength between the poured concrete and the drilled hole is improved advantageously.
本发明提供一种钻孔灌注桩施工方法，包括以下步骤：S1，桩孔定位，确定平面位置后，安装图纸测量并标记出桩孔位置，以备下步施工使用；S2，平整场地，清理场地杂物，夯实平整；S3，护筒埋设，采用钢板卷制焊接成护筒，护筒的高度大于等于1.0m，将护筒与桩孔对应埋设与地面；S4，钻进成孔，采用钻机在桩孔位置分别成孔并清理；S5，钢筋笼安放，将钢筋笼起吊并放入桩孔内部；S6，混凝土灌注，向桩孔内部灌注混凝土；本发明中的方法简单，通埋设护筒能够对钻孔的桩位进行定位，避免钻孔出现偏差，保证钻孔精度，护筒采用钢板卷制焊接制成，减少设备成本支出，钻孔后及时清理钻孔内部的残渣，有利于提升灌注后混凝土与钻孔之间的结合强度。
