Ultra-long spiral drilling machine for mud flat cast-in-place pile and construction method
The invention discloses an ultra-long spiral drilling machine for a mud flat cast-in-place pile and a construction method. The ultra-long spiral drilling machine mainly comprises a pile frame and a drilling system. The pile frame comprises a chassis, telescopic oil cylinder supporting legs, walking oil cylinders and detachable stand columns. The drilling system comprises a power head, the top of the power head is connected with a concrete pumping pipeline, the bottom of the power head is connected with a spiral drilling tool, the spiral drilling tool comprises a spiral drilling rod and a spiral drilling bit, and conical alloy cutting teeth are arranged on the spiral drilling bit; the power head is arranged on the stand column in a sliding mode, a pulley assembly is arranged on the top of the stand column, the power head is hung on the stand column, and the other end of an arranged traction rope is connected with a winch. And a drilling tool cleaning device is arranged on one side of the spiral drilling tool. The spiral drill bit is a high-strength alloy cutting tooth suitable for the mud flat area, the high-strength alloy cutting tooth is used for adapting to the complex geological condition of the Yellow River mud flat area, and the technical problem that an existing spiral drilling machine cannot adapt to the complex geological condition of the mud flat area is effectively solved.
本发明公开了一种滩区灌注桩用超长螺旋钻机及施工方法，主要包括桩架及钻进系统；所述桩架包括底盘、伸缩油缸支腿、行走油缸、可拆卸立柱；所述钻进系统包括动力头，所述动力头的顶部连接有混凝土泵送管道，底部连接有螺旋钻具，所述螺旋钻具包括螺旋钻杆和螺旋钻头，所述螺旋钻头上设置有锥形合金截齿；所述动力头滑动设置在所述立柱上，所述立柱的顶部设置有滑轮组件，所述动力头吊设在所述立柱上，所设置的牵引绳的另一端连接有卷扬机；所述螺旋钻具一侧设置有钻具清理装置。本申请的螺旋钻头为适用于滩区的高强度合金截齿，通过使用所述高强度合金截齿以适应黄河滩区复杂的地质情况，有效地解决现有螺旋钻机无法适应滩区复杂地质情况的技术问题。
