Construction process for replacing mud protecting wall
The invention discloses a construction process for replacing a mud protecting wall. The construction process comprises the following steps that a pile-stabilizing platform is built and fixed to a construction machine position; a pile holder of the pile-stabilizing platform is opened; a mechanical device is adopted to drill an outer steel reel to the bedrock; a vertical compound type powerful drilling machine is mounted; an inner steel reel is hoisted into the outer steel reel by adopting a special lifting tool; and the vertical compound type powerful drilling machine is started, hole forming drilling is carried out, as the drilling depth is expanded, the inner steel reel follows a drilling tool system to enter a hole, the drilling tool system performs downward drilling till the designed elevation is reached, after the hole forming is completed, the inner steel reel is taken out from the pile hole and withdrawn from the drilling tool system, the vertical compound type powerful drillingmachine is withdrawn from a construction site, and the hole forming is finished. The construction process has the beneficial effects that mud is not needed, the use of construction consumables is reduced, the working environment of the construction personnel is improved, the influence of waste residues generated by the hole forming on the ecological environment is low, the waste residues can be directly discharged into the sea without being treated, the two steel reels can be reused, the economical efficiency is good, and the construction process is safer.
本发明公开了一种替代泥浆护壁的施工工艺，将稳桩平台搭建固定在施工机位，打开稳桩平台自带的抱桩，采用机械设备将外钢卷筒打至基岩定,安装竖向复合式强力钻机,采用专用吊具吊装内钢卷筒至外钢卷筒中；开启竖向复合式强力钻机，进行成孔钻进，随着钻孔深度扩展，内钢卷筒跟随钻具系统进入孔内,钻具系统向下钻进，钻至设计标高，成孔完成后，将内钢卷筒提出桩孔撤出钻具系统，竖向复合式强力钻机撤离施工现场，成孔结束；本发明的有益效果是，不需要使用泥浆，减少了施工耗材的使用，提高施工人员作业环境，成孔产生的废渣对生态环境影响低，无需处理可直排海中，两个钢卷筒可重复利用，经济性好，且施工过程更安全。
