Static pressure hole guiding device, pile sinking construction device and pile sinking construction method
The invention discloses a static pressure hole guiding device which comprises a pipe body and a force transmission assembly, the force transmission assembly is used for connecting the pipe body with a clamping and pressing mechanism of a static pile driver so that the pipe body can bear downward static pressure of the static pile driver, and the lower portion of the pipe body is of a hollow structure. The invention further provides a pile sinking construction device and a construction method for conducting static pressure pile sinking construction through the pile sinking construction device. According to the static pressure hole guiding device, the pile sinking construction device and the pile sinking construction method, when the static pressure hole guiding device works, the static pressure hole guiding principle is adopted, a large spiral drilling machine is not needed, a special static pressure pile planting machine with a specific function is not needed, and only a common conventional static pile driver for in-situ construction is needed; the construction process is simple, convenient and environment-friendly, the cost is low, a middle hole post-grouting method can be conveniently adopted, the method can be widely applied to pile sinking construction of various types of pipe piles commonly used in civil and constructional engineering, the pile forming quality is high, and the application prospect is good.
本发明公开了一种静压引孔装置，包括管体以及用于将所述管体与静力压桩机的夹压机构相连，以使管体承受静力压桩机的向下静压力的传力组件，所述管体的下部为中空结构。本发明还提供一种沉桩施工装置及一种利用上述的沉桩施工装置进行静压沉桩施工的施工方法。本发明的静压引孔装置、沉桩施工装置及沉桩施工方法，静压引孔装置工作时采用静压引孔原理，不需要大型螺旋钻孔机械，不需要特殊的具有特定功能的专用静压植桩机，利用原地施工的普通常规静力压桩机即可，施工过程简便、环保、成本低，且便于采用中孔后注浆方法，可广泛适用于土木建筑工程常用的各种型号的管桩的沉桩施工，成桩质量高，应用前景好。
