The invention provides a grouting device and a pile end post-grouting construction method. The grouting device comprises a grout bundling bag and a grouting pipe. The grouting pipe is connected with the slurry bundling bag and is used for grouting slurry into the slurry bundling bag; the pulp bundling bag is used for storing the pulp and expanding outwards to form an expanded head; the pulp bundling bag is provided with a closed area and a pulp penetrating area, the closed area and the pulp penetrating area are arranged in the vertical direction, and the closed area is located above the pulp penetrating area; and the slurry permeating area is used for allowing the slurry to seep after a preset pressure value is reached. By means of the configuration, the grout bundling bag has the open type grouting function and the closed type grouting function, the structure of the grouting device is simplified, and the grouting steps are optimized; and meanwhile, the slurry is stored to form an expanded head and the slurry is allowed to seep from the slurry bundling bag, so that the physical extrusion effect and the chemical cementation effect of the slurry are fully exerted.
本发明提供一种注浆装置以及桩端后注浆施工方法，所述注浆装置包括：束浆袋以及注浆管；所述注浆管与所述束浆袋连接，用于向所述束浆袋中灌注浆体；所述束浆袋用于存储所述浆体，并向外扩张以形成扩大头；所述束浆袋具有密闭区和透浆区，所述密闭区与所述透浆区沿竖直方向排布，且所述密闭区位于所述透浆区的上方；所述透浆区用于在达到预定压力值后，允许所述浆体渗出。如此配置，束浆袋具有开式注浆和闭式注浆两种功能，简化了注浆装置的结构，优化了注浆步骤；同时，储存浆体形成扩大头且允许浆体自束浆袋中渗出，充分发挥了浆体的物理挤压作用和化学胶结作用。
