Bare rock riverbed steel pipe pile construction equipment and construction method
The invention provides bare rock riverbed steel pipe pile construction equipment and a construction method, and relates to the technical field of steel pipe pile construction.The bare rock riverbed steel pipe pile construction equipment comprises a rotating mechanism and a steel pipe drill bit, the rotating mechanism comprises a drill rod, one end of the drill rod is connected with the steel pipe drill bit, and the steel pipe drill bit is the same as a steel pipe pile in shape; the end, away from the drill rod, of the steel pipe drill is provided with drill teeth. According to the bare rock riverbed steel pipe pile construction equipment, on one hand, the steel pipe drill bit plays a role of a steel casing in the prior art, on the other hand, in the drilling process, the drill teeth on the steel pipe drill bit compact rock soil, waste residues in a steel pipe pile hole site are brought out when the drill rod lifts and pulls the steel pipe drill bit, the steel pipe pile hole site is convenient to clean, and the construction efficiency is high; due to the fact that a steel casing is not additionally arranged, after the steel pipe drill bit lifts slag, under the action of water flow and soil layer lateral pressure, silting can be carried out in a hole after the steel pipe drill bit is pulled out, a covering layer is formed, and vibration sinking construction of the steel pipe pile can be facilitated.
本发明提供了一种裸岩河床钢管桩施工设备及施工方法，涉及钢管桩施工技术领域，所述裸岩河床钢管桩施工设备包括回旋机构及钢管钻头，回旋机构包括钻杆，钻杆的一端连接有钢管钻头，钢管钻头的外部形状与钢管桩形状相同，钢管钻头在远离钻杆的一端设有钻齿。本发明的裸岩河床钢管桩施工设备，钢管钻头一方面起到现有技术中钢护筒的作用，另一方面钢管钻头上的钻齿在钻孔的过程中，挤密岩土，在钻杆提拉钢管钻头时将钢管桩孔位内的废渣带出，实现钢管桩孔位的方便清理，施工效率高；由于没有额外设置钢护筒，钢管钻头提渣后，在水流、土层侧压力的作用下，钢管钻头拔出后的孔内会回淤，形成覆盖层，便可方便钢管桩的振动下沉施工。
