Precast pile construction method capable of dissipating foundation soil pore water pressure and preventing pile body from floating
The invention belongs to the technical field of precast piles, and particularly relates to a precast pile construction method capable of dissipating foundation soil pore water pressure and preventinga pile body from floating. By changing the stress state of the precast pile in the construction process, an added drainage plate is attached to the pile body of the precast pile and enters a preset stratum along with pile sinking of the precast pile, and construction equipment does not need to be added, then the pore water pressure generated in foundation soil in the precast pile construction process can be effectively dissipated, floating and horizontal displacement generated in the precast pile construction process are effectively controlled, damage to surrounding adjacent buildings, roads and pipelines is avoided, and the influence on the surrounding environment is reduced.
本发明属于预制桩技术领域，具体涉及具有消散地基土孔隙水压力防止桩身上浮的预制桩施工方法，通过改变预制桩施工过程中的受力状态，在预制桩桩体上贴挂增加的排水板跟随预制桩沉桩进入预定地层，无需增加施工设备，即可有效消散预制桩施工过程中在地基土中产生的孔隙水压力，使得预制桩施工过程中的产生上浮和水平位移得到有效控制，避免对周边紧邻建筑、道路及管线产生危害，减少对周边环境影响。
