Down-hole hammer rock crushing construction method

The invention discloses a down-the-hole hammer rock crushing construction method, which belongs to the technical field of building construction, and comprises the following steps: measuring and placing points, placing a drilling machine in place, putting down a pile casing, drilling and forming a hole by a down-the-hole drill, cleaning the hole, putting down a reinforcement cage, pouring concrete, and maintaining a formed pile. According to the down-the-hole hammer rock crushing construction method, the large-diameter down-the-hole hammer and the rotary drilling rig are combined, and the problem that drilling of the rotary drilling rig in an extremely hard layer is slow can be effectively solved. 本发明公开了一种潜孔锤岩石破碎施工方法，属于建筑施工技术领域，包括以下步骤：测量放点-钻机就位-下方护筒-潜孔钻钻进成孔-清孔-下方钢筋笼-灌注混凝土-成桩养护。本发明示例的潜孔锤岩石破碎施工方法，将大直径潜孔锤与旋挖钻机相结合，可有效解决旋挖钻机在极硬层的钻进缓慢的问题。
