Cast-in-situ bored pile construction technology
The invention discloses a cast-in-situ bored pile construction technology, and relates to the field of cast-in-situ piles. The cast-in-situ bored pile construction technology comprises the following steps that a pile casing is installed; drilling a pile hole; placing a reinforcement cage; a grouting pipe is lowered, and the lower end of the grouting pipe is inserted into the pebble bed at the bottom of the pile hole; lowering a conduit; pouring concrete; pile body maintenance and concrete solidification; mortar is injected into the pebble bed at high pressure through the grouting pipe. The method has the effects that the situation of sinking of the filling pile is reduced, and the stability of the filling pile is improved.
本申请公开了一种钻孔灌注桩施工工艺，涉及灌注桩的领域，其包括如下步骤：安装护筒；钻设桩孔；安放钢筋笼；下放注浆管，并将注浆管的下端插入至桩孔底部的卵石层；下放导管；灌注混凝土；桩体养护，混凝土凝固；通过注浆管向卵石层高压注入砂浆。本申请具有减少灌注桩下沉的情况发生，提升灌装桩稳定性的效果。
