All-casing pipe shoe and down-the-hole hammer pipe-following dual-power rock breaking construction method
The invention relates to the technical field of down-the-hole hammer rock breaking construction methods, and discloses an all-casing pipe shoe and down-the-hole hammer pipe-following dual-power rock breaking construction method. The all-casing pipe shoe and down-the-hole hammer pipe-following dual-power rock breaking construction method comprises the following steps: (1) performing construction preparation; (2) installing an all-casing pipe, lifting a down-the-hole hammer, and enabling the down-the-hole hammer to extend into the all-casing pipe from top to bottom; (3) performing advanced trephine hole guiding on a pipe shoe, and the pipe shoe synchronously performing drilling construction and chiseling construction on a rock stratum; synchronously adopting a gas-liquid dust falling device and a tumbling barrel slag collecting device, so that floating objects are forced to drop and muck is collected in a centralized manner; (4) guiding a hole to a designed groove depth, and pulling out the all-casing pipe; (5) finishing continuous wall hole guiding; (6) using double-wheel milling equipment for milling and repairing the hole to form a groove, and cleaning the hole for the first time; (7) manufacturing and mounting a reinforcing mesh, and mounting a pouring guide pipe; and (8) cleaning the hole for the second time, and pouring concrete. Broken rock slag is blown out of the hole, repeated breaking is avoided, and the rock breaking efficiency is improved; and generated dust pollution is reduced, muck and rock debris are collected, cleared and transported in a centralized mode, and environment-friendly construction is achieved.
本发明涉及潜孔锤破岩施工方法的技术领域，公开了全套管管靴与潜孔锤跟管双动力破岩施工方法，步骤:(1)、施工准备；(2)、安装全套管，提升潜孔锤，将潜孔锤沿自上而下伸入全套管的内部；(3)、管靴进行超前环钻引孔，管靴对岩层同步进行钻施工和凿施工；同步采用气液降尘装置和串筒集渣装置，实现逼降漂浮物和集中收纳渣土；(4)、引孔至设计槽深、拔除全套管；(5)、连续墙引孔完毕；(6)、双轮铣设备铣修孔成槽，进行第一次清孔；(7)、钢筋网片制作和安装，灌注导管安装；(8)、第二次清孔、灌注混凝土。破碎的岩渣吹出孔外，避免了重复破碎，提高破岩效率；减少产生的粉尘污染，渣土、岩屑集中收集清运，绿色环保施工。
