Hydraulic reclamation deep soft foundation one-time drainage consolidation treatment system and method
The invention discloses a hydraulic reclamation deep soft foundation one-time drainage consolidation treatment system and method. The system comprises a vertical drainage plate, a horizontal drainageand sealing combination body, an underwater vacuum water pumping system, a viscous backfill soil layer, a sandy backfill soil layer, a sealing wall, and an underwater heavy hammer; the horizontal drainage and sealing combination body is specifically provided with sand lattices; the head of the vertical drainage plate penetrates through a lower-layer low-density PE geomembrane of the sand latticesand enters the sandy material; the underwater vacuum pumping system comprises a vacuum air-water separation box arranged underwater; and the underwater heavy hammer tamps the surface of the sandy backfill soil layer. According to the reinforcing method for hydraulic reclamation of deep soft soil, the low-position vacuum preloading technology, the surcharge preloading technology and the underwatertamping technology are comprehensively applied, the rapid and safe one-time hydraulic reclamation of the deep soft soil reinforcing effect is achieved, the construction efficiency is improved, and thereinforcing effect is improved.
本发明公开了一种吹填深厚软基一次性排水固结处理系统及方法，该系统包括竖向排水板、水平排水兼密封联合体、水下真空抽水系统、黏性回填土层、砂性回填土层、密封墙及水下重锤，水平排水兼密封联合体具体有砂格，竖向排水板板头刺穿砂格的下层低密度PE土工膜并进入砂性材料中，水下真空抽水系统包括一设置于水下的真空气水分离箱，水下重锤夯击作用于砂性回填土层表面。本发明针对吹填深厚软土的加固方法，采用了低位真空预压、堆载预压及水下夯实技术综合运用，达到快速、安全的一次性吹填深厚软土加固效果，提高了施工效率，增加了加固效果。
