Soft-soil foundation treatment method combining disturbance at different depths with drainage consolidation
The invention discloses a soft-soil foundation treatment method combining disturbance at different depths with drainage consolidation. Multiple drainage bodies, multiple disturbance medium guide pipes and special machinery are arranged, the drainage bodies are hit into a to-be-treated soft soil body to accelerate drainage consolidation of the to-be-treated soft soil body, the special machinery provides a disturbance medium for the disturbance medium guide pipes, each drainage body is a plastic drainage plate or a bagged sand well, and small holes are formed in each disturbance medium guide pipe. The soft-soil foundation treatment method specifically includes the following steps: leveling a site; hitting and arranging the drainage bodies; initially disturbing the soil body; adopting a surcharge preloading or vacuum preloading device to pressurize the to-be-treated soft soil body; disturbing the to-be-treated soft soil body for multiple times according to needs; finishing construction. By the soft-soil foundation treatment method, seepage coefficient can be improved by disturbing soil bodies different in depth, so that soil body solidification speed and soil body treatment depth can be increased, long-time creep deformation of the soil bodies and upper-portion stack load can be reduced, and cost can be lowered.
