Advanced slant thread expanding body composite pile, construction equipment and construction technology thereof
The invention provides an advanced oblique thread expanding body composite pile which comprises a stirring pile and a plurality of steel pipe piles or precast piles inserted into the stirring pile, an expanding body is arranged at the bottom end of the stirring pile, the steel pipe piles or precast piles are connected through connectors, an expanding head is arranged at the bottom end of the steel pipe pile or precast pile at the lowest end, and the expanding head is connected with the stirring pile. The expanding head is positioned in the expanding body; the invention further provides construction equipment of the advanced oblique thread expanding body composite pile. The construction equipment comprises screwing equipment, wherein the tail end of a suspension arm of the screwing equipment is provided with a rotary hydraulic power head and a plurality of steel pipe piles which are driven by the rotary hydraulic power head and are coaxially arranged in series; the invention further provides a construction technology of the construction equipment of the advanced slant thread expanding body composite pile. By means of the mode, the problems that conventional construction equipment is inconvenient to construct in a foundation pit, long in construction period and insufficient in bearing capacity are solved.
本发明提出了一种超前斜向螺纹扩大体复合桩，包括：搅拌桩和插设于搅拌桩内的多根钢管桩或预制桩，其中在所述搅拌桩的底端设置有扩大体，多根钢管桩或预制桩之间通过接头连接，在最低端钢管桩或预制桩的底端端部设置有扩大头，所述扩大头位于扩大体中；本发明还提出了一种超前斜向螺纹扩大体复合桩的施工设备包括：旋拧设备，在所述旋拧设备的吊臂末端设置有旋转液压动力头以及由旋转液压动力头驱动的同轴串联设置的多根钢管桩；本发明还提出了一种超前斜向螺纹扩大体复合桩的施工设备的施工工艺。通过上述方式，解决了常规的施工设备在基坑内施工不便、施工周期长、承载力不足的问题。
