Deep soft foundation reinforcement treatment method

The invention provides a deep soft foundation reinforcement treatment method. The deep soft foundation reinforcement treatment method comprises the following steps: leveling the site of a region to be reinforced; filling a sand bed; inserting a vertical drainage body; digging sealing ditches; laying vacuum lines; mounting a vacuum unit, vacuumizing, laying geotextile on a film when the vacuum degree under the film reaches 80 kPa or above and is stable, and starting heaped loading construction; after the foundation in the region to be reinforced reaches the control consolidation degree (60-80 percent), relieving pressure step by step till stopping vacuumizing; after vacuum pre-pressing unloading, carrying out precipitation construction; performing dynamic compaction; and leveling the site to the construction level. The deep soft foundation reinforcement treatment method combines the functions of vacuum negative pressure, heaped loading positive pressure and dynamic load to form a static-dynamic consolidation compounded reinforcement technology. Compared with a traditional drainage consolidation method, the deep soft foundation reinforcement treatment method shortens 1/3 of the construction period and reduces 30 cm or above of post-construction settlement; and compared with a drainage consolidation + composite foundation secondary treatment method, the deep soft foundation reinforcement treatment method lowers the construction cost by 20-40 percent, is more remarkable in soft foundation reinforcement effect and is suitable for large-area application and popularization.
