Application of vacuum preloading for soft foundation treatment in grain storage
The application of vacuum preloading for soft foundation treatment in grain storage is introduced from its principle, design, construction and the inspections.Its obvious effect is proved by example.The east coast of China is the most developed economical area and major grain and oil manufacturers.Many grain and oil depots have been established.However, in the places where the depots located, soil is soft dirt with low strength grade, high compressibility, small permeability and high possibility of plastic flow, has increased difficulties of grain and oil depots foundation construction.Without enough knowledge of soft soil and lacking of proper foundation construction method and good technology, depots may slip due to foundations erosion, and big settlement.If the structure slips, equipments for aeration, dehumidifier, antivirus equipment cannot work well.Based on the statement above, reasonable and effective methods for soft soil foundation work is the key point for construction of high quality and high standard grain and oil depots.This paper mainly discussed when we do depots construction work on the soft soil foundation, exact calculation, construction method and result test of fasten method for the soft foundation under the vacuum circumstance ofpreloading.
