Super-thick covering layer large-diameter rock-socketed cast-in-place pile forming construction equipment
The invention relates to the technical field of rock-socketed cast-in-place piles, and discloses super-thick covering layer large-diameter rock-socketed cast-in-place pile forming construction equipment. The construction equipment comprises a full-hydraulic reverse circulation drilling machine, a sedimentation tank and multiple stages of mud tanks which are sequentially arranged and are in communication, and the full-hydraulic reverse circulation drilling machine drills through a covering layer and drills into a rock stratum to form a pile hole; in the drilling process, a gravel pump is started to carry out pumping reverse circulation hole cleaning; and a reinforcement cage and a pouring guide pipe used for pouring concrete into the pile hole to form a rock-socketed cast-in-place pile are put into the pile hole, and after the lower portion of the pouring guide pipe is in place, an air compressor is started to conduct air lift reverse circulation hole cleaning. The super-thick covering layer large-diameter rock-socketed cast-in-place pile forming construction equipment has the advantages of being good in slurry wall protection effect, high in slag discharging efficiency, high in drilling speed, high in rock stratum drilling capacity, good in reverse circulation hole cleaning effect, good in environment-friendly effect and the like.
本发明涉及嵌岩灌注桩的技术领域，公开了超厚覆盖层大直径嵌岩灌注桩成桩施工设备，包括全液压反循环钻机、沉淀池以及多级依序排布连通的泥浆池，全液压反循环钻机钻过覆盖层并钻进岩层，形成桩孔；在钻进的过程中，启动砂石泵进行泵吸反循环清孔；桩孔内下入有钢筋笼以及用于往桩孔内灌注混凝土以形成嵌岩灌注桩的灌注导管，当灌注导管下方到位后，启动空压机进行气举反循环清孔；本发明提供的超厚覆盖层大直径嵌岩灌注桩成桩施工设备，具有泥浆护壁效果好、出渣效率高、钻进速度快、岩层钻凿能力强、反循环清孔效果好以及绿色环保效果好等优点。
