摘　　要：与传统真空堆载联合预压法相比,大泵量节能真空堆载预压软基处理施工技术是通过55kW节能真空泵连接水气分离罐替代7.5kW射流式真空泵,形成真空预压系统,改变了真空负压的发生原理,并新增掌形接头直排技术及自动抽排水气节能装置,进一步提高软基处理工效,减少用电安全隐患,简化现场施工管理,提高环保效益。Compared with the traditional vacuum-surcharge preloading method,a 55 kW energy-saving vacuum pump connected with a few water-gas separating tanks has been used in this construction technology,which innovatively changes the theory about the formation of vacuum and establishes the system of vacuum preloading. At the same time,hand-joints and the automatic water-gas extraction device are added,which further achieves a higher efficiency,decreases electrical safety risks,simplifies construction management and improves environmental benefits.
