Analysis of Sandless Vacuum Prepressing Technology and Reinforcement Effect Based on Blow Fill Soil
There are many municipal engineering construction sites in coastal cities that use hydraulic reclamation,and the excavation of deep foundation pits is different from the excavation of undisturbed soil.In the article,research was conducted on the soft foundation treatment of Section A of Xidong Road.The project adopted sand free vacuum preloading,and after 6 months of vacuum pumping,it was found that this technology has a very good reinforcement effect.At the same time,the corresponding physical and mechanical indicators of the soft foundation soil have also been greatly improved,which can meet the requirements of engineering design.Based on this,the article analyzes the use of sand free vacuum preloading technology in municipal project engineering and its reinforcement effect,explores technical management and auxil-iary management measures,ensures construction safety and orderly development,and helps to significantly shorten the project construction cy-cle and save costs.The research in the article can provide necessary reference for similar projects.
