Sleeve separation type static pressure hole guiding device, pile sinking construction device and pile sinking construction method
The invention discloses a sleeve separation type static pressure hole guiding device which comprises a separation type sleeve inner barrel and a separation type sleeve outer barrel, the separation type sleeve inner barrel comprises a lower hollow soil taking section and an upper connecting section, and the upper connecting section is movably sleeved with the separation type sleeve outer barrel; and a detachable connecting piece is arranged between the outer cylinder of the separated sleeve and the upper connecting section. The invention further discloses a pile sinking construction device and a pile sinking construction method. According to the sleeve separation type static pressure hole guiding device, the pile sinking construction device and the pile sinking construction method, a conventional static pile driver does not need to be modified at all, the construction method is simpler and more convenient to implement, the working efficiency can be remarkably improved, meanwhile, the single-time hole guiding depth can not be limited by the holding and pressing stroke of the static pile driver, the hole guiding depth is large and can be accurately controlled, and the construction efficiency is improved. The pile cutting length after pile sinking can be reduced, the economical efficiency of application of the prefabricated pipe pile is improved, and the construction cost is saved.
本发明公开了一种套筒分离式静压引孔装置，包括分离式套筒内筒与分离式套筒外筒，所述分离式套筒内筒包括下部中空取土段和上部连接段，所述分离式套筒外筒可活动地套设于所述上部连接段外，所述分离式套筒外筒与所述上部连接段之间设有可拆卸连接件。本发明还公开了一种沉桩施工装置及一种沉桩施工方法。本发明的套筒分离式静压引孔装置、沉桩施工装置及沉桩施工方法，无需对常规静力压桩机进行任何改造，施工方法更简便易行，可显著提高工作效率，同时，单次引孔深度可不受静力压桩机抱压行程限制，引孔深度大且可精确控制，能够减少沉桩后的截桩长度，提高预制管桩应用的经济性节约工程造价。
