Sludge reclamation foundation solidification structure and method utilizing vacuum preloading and gravel piles
The invention discloses a dredger fill sludge foundation solidification structure and method utilizing vacuum preloading and gravel piles, the dredger fill sludge foundation solidification structure comprises a first sealing film, a plurality of drainage plate layers and gravel piles arranged at intervals, and the bottom face of a target site is sequentially dredger fill sludge from bottom to top to form a plurality of layers of sludge filling bodies; the drainage plate layers are laid on the upper surfaces of the sludge filling bodies, the first sealing film is laid on the uppermost drainage plate layer, and pile holes allowing gravel piles to be inserted therein are vertically drilled in the sludge filling bodies. The drainage pipeline of each drainage plate layer is communicated with the gravel pile, the grouting pump and the vacuum pump are started and stopped synchronously, the grouting pump injects curing grout into part of or all the pile holes through the grouting pipe, and the vacuum pump is communicated with a drainage port of the drainage pipeline and vacuumizes the lower portion of the first sealing film. A hydraulic reclamation sludge foundation solidification method utilizing vacuum preloading and gravel piles comprises the hydraulic reclamation sludge foundation solidification structure, rapid drainage can be achieved, and the bearing capacity of the solidified foundation is high.
本发明公开了一种利用真空预压、碎石桩的吹填淤泥地基固化结构及方法，吹填淤泥地基固化结构包括第一密封膜和若干排水板层、间隔设置的碎石桩，在目标场地底面上由下至上依次吹填淤泥形成若干层淤泥堆填体，各排水板层铺设于各层淤泥堆填体上表面，第一密封膜铺设于最上方的排水板层的上方，淤泥堆填体竖直钻有可供各碎石桩插入的桩孔；各排水板层的排水管道与碎石桩连通，注浆泵与真空泵同步启停，注浆泵通过注浆管向部分或全部桩孔内注入固化浆液，真空泵与排水管道的排水口连通并对第一密封膜下方抽真空。一种利用真空预压、碎石桩的吹填淤泥地基固化方法，包括上述吹填淤泥地基固化结构，可实现快速排水且固化后地基承载能力高。
