Device and method for dissipating excess pore water pressure generated by pile sinking of prefabricated pipe pile
The invention relates to the technical field of buildings, in particular to a device and method for dissipating excess pore water pressure generated by pile sinking of a prefabricated tubular pile, comprising a tubular pile, an end plate arranged at the end of the tubular pile and a pile tip arranged on the bottom surface of the end plate, the device further comprises a flexible plug and filler, the flexible plug is used for penetrating through the end plate to be inserted into the end of the tubular pile core, the filler is arranged in a filling cavity of the flexible plug and melted through heat absorption, a first through hole used for communicating the filling cavity with the tubular pile core is formed in the inserting end face of the flexible plug, and a second through hole is formed in the pile tip. And the filler absorbs heat and melts, so that the second through holes are communicated with the first through holes to form a hydraulic channel along the pipe pile core. According to the device, it can be guaranteed that soil cannot enter the tubular pile cavity in the pile sinking process, it can be guaranteed that an effective drainage channel is formed through the tubular pile cavity after pile sinking is completed, excess pore water pressure generated during pile sinking of the prefabricated tubular pile is rapidly dissipated, and the device has the advantages of being simple in structure, convenient to install, good in drainage effect and the like and can effectively guarantee the engineering quality.
本发明涉及建筑技术领域，具体涉及一种消散预制管桩沉桩产生的超孔隙水压力的装置及方法，包括管桩、设于管桩端部的端头板和设于端头板底面的桩尖，所述装置还包括用于贯穿端头板以插入管桩桩芯端部内的柔性塞和设于柔性塞的填充腔内且通过吸热融化的填充物，所述柔性塞的插入端面设有用于连通填充腔与管桩桩芯的第一通孔，所述桩尖设有第二通孔，所述填充物吸热融化以使第二通孔与第一通孔连通形成沿管桩桩芯的水力通道。本发明既能确保沉桩过程中土体无法进入管桩空腔，又能保证沉桩结束后利用管桩空腔形成有效排水通道，快速消散预制管桩沉桩时产生的超孔隙水压力，该装置具有结构简单、安装方便、排水效果好等优点，能够有效保障工程质量。
