Double-power down-the-hole hammer casing-following drilling construction structure for cast-in-place pile of deep and thick rock-filled layer
The invention relates to the technical field of pile forming construction, and discloses a deep and thick rock-filled layer cast-in-place pile dual-power down-the-hole hammer casing-following drilling construction structure which comprises a down-the-hole hammer drilling machine, an operation platform installed at the top of a steel sleeve and a hopper installed on the operation platform and used for pouring concrete into a pile hole to form a pile body. The down-the-hole hammer drilling machine is provided with a drill rod, an inner through hole is formed in the drill rod, a down-the-hole hammer is arranged at the bottom of the drill rod, the drill rod is sleeved with a steel sleeve, and a slag discharging channel is formed between the steel sleeve and the drill rod. The inner through hole is connected with an air compressor through an air inlet pipe, and the air compressor injects high-pressure air into the inner through hole to drive the down-the-hole hammer to vibrate. The drill rod is connected with the inner side power head, the sleeve is connected with the outer side power head, and in the process of drilling in a soil layer, the outer side power head drives the steel sleeve to drill in advance, and the down-the-hole hammer drills along with the sleeve; in the drilling process of the rock-filled layer, the inner side power head drives the down-the-hole hammer to drill in advance, and the steel sleeve drills along with the pipe and abuts against the rock stratum; in the rock stratum drilling process, the down-the-hole hammer drills independently.
本发明涉及成桩施工的技术领域，公开了深厚填石层灌注桩双动力潜孔锤跟管钻进施工结构，包括潜孔锤钻机、安装在钢套管顶部的作业平台以及安装在作业平台上且往桩孔中灌注混凝土以形成桩身的料斗；潜孔锤钻机具有钻杆，钻杆中具有内通孔，钻杆的底部具有潜孔锤，钻杆外套设有钢套管，钢套管与钻杆之间形成有排渣道；内通孔通过进气管与空压机连接，空压机往内通孔中注入高压气体驱动潜孔锤振动；钻杆与内侧动力头连接，套管与外侧动力头连接，在土层中钻进过程中，外侧动力头驱动钢套管超前钻进，潜孔锤跟管钻进；在填石层钻进过程中，内侧动力头驱动潜孔锤超前钻进，钢套管跟管钻进，并抵接在岩层上；在岩层钻进过程中，潜孔锤独立钻进。
