摘要
针对真空预压施工中由于侧向密封系统密封性能差,导致真空预压的加固效果不理想这一问题,提出采用单排粘土密封墙结合人工插膜的侧向密封技术。通过现场试验表明,该技术施工工艺简便,密封效果良好,施工成本较低,具有良好应用价值。
Aiming at sloving the problem of ineffective treating performance due to the poor side direction leakage-proof system during the vacuum preloading construction, a new advanced technique of single-line clay soil sealing wall of mixing piles combined with inserting film is introduced. This new technique is proved by field tests to be conveniently constructing, lower construction cost and effective for improving consolidation of soft clay foundation and has a great value of popularization.
