Foundation pit inclined pile construction method
The invention relates to the field of foundation pit inclined pile construction, and particularly discloses a foundation pit inclined pile construction method which comprises the following steps: S1, preparing for construction, leveling a site, setting a pile position in a to-be-excavated peripheral area of a foundation pit, and calculating a pile diameter, a pile length and an inclined angle; s2, soil taking and drilling are carried out, and drilling is carried out at the pile position according to the set inclination angle to the set depth to form an inclined pile hole; s3, hole cleaning and formed hole inspection are conducted, specifically, a hole cleaning drill bit is used for hole cleaning, and the hole forming quality is inspected; s4, a reinforcement cage is put down, and a guide device used for enabling the head end of the reinforcement cage to be kept in the coaxial state with the inclined pile hole is arranged on the reinforcement cage; a lower cage supporting device is arranged at the opening of the inclined pile hole, so that the reinforcement cage slides into the inclined pile hole in the direction parallel to the axis of the inclined pile hole; and S5, pipe lowering and grouting are conducted, specifically, a guide pipe is lowered in the reinforcement cage, and concrete is poured into the inclined pile hole. The device has the effect that the reinforcement cage can be lowered to a bearing layer in the state that the reinforcement cage is not hung on the inner wall of the inclined pile hole and is coaxial with the inclined pile hole.
本申请涉及基坑斜桩施工领域，具体公开了一种基坑倾斜桩施工方法，其包括以下步骤：S1.施工准备，平整场地，在基坑待开挖外围区域设置桩位，并计算桩径、桩长及倾斜角度；S2.取土钻进，在桩位处按设定倾斜角度钻孔至设定深度形成斜桩孔；S3.清孔及成孔检查，使用清孔钻头进行清孔，并对成孔质量进行检查；S4.下钢筋笼，在钢筋笼上设置用于使得钢筋笼头端保持在与斜桩孔同轴状态的导向装置；再在斜桩孔孔口处设置下笼支撑装置以使钢筋笼以平行于斜桩孔轴线的方向滑入斜桩孔中；S5.下管注浆，在钢筋笼中下放导管并向斜桩孔中灌注混凝土。本申请具有能使钢筋笼以不挂斜桩孔内壁且与斜桩孔同轴的状态下放至持力层的效果。
