Continuous forced drainage and compaction combined soft foundation treatment technical method
The invention relates to a continuous forced drainage and compaction combined soft foundation treatment technical method. According to the continuous forced drainage and compaction combined soft foundation treatment technical method, spring soft downcast pipes are transversely arranged at a certain intervals in a certain depth range inside a soil mass according to a reinforcing depth of dredger fill and a soil mass permeability coefficient, both ends of the spring soft downcast pipes are connected with a vacuumizing device by sealing devices and a transverse drainage system is formed inside the reinforced soil mass to carry out forced drainage; after the groundwater level of the field is descended to the position at a distance of 2 to 4m from the ground, drainage consolidation of a foundation is accelerated by repeated variable-energy compaction. The drainage system used by the method is arranged inside the reinforced soil mass; a drainage effect is obvious; in the compaction construction, drainage is synchronously carried out; dissipation of an excess pore water pressure caused by compaction is greatly accelerated; quench time of compaction is shortened; combination of the forced drainage and dynamic compaction technical advantages is realized; the continuous forced drainage and compaction combined soft foundation treatment technical method has the advantages of short construction period, good reinforcing effect, low cost, resource saving and the like.
