将塑料排水板用插板机插入软土中,然后在土面加载予压(或采用真空予压),土中水将沿塑料板的排水通道逸出,地基得以加固。这种方法称为塑料板排水法,其原理与砂井法相同。塑料板排水法在国外已成功应用于公路、铁路、港口、房屋、机场及围海造地等软基加固工程中。在我国天津新港已经应用和将要应用的塑料板已达20余万米;连云港计划今年试验要用2万米,其他(如上海、宁波等地)软基
The plastic drainage board inserted into the soft board with a plug-in machine, and then loaded in the soil surface pressure (or vacuum pressure), soil water will escape along the plastic drainage channels, the foundation can be reinforced. This method is called plastic plate drainage method, the principle and the sand method the same. Plastic board drainage law in foreign countries has been successfully used in highways, railways, ports, houses, airports and reclamation and other soft ground reinforcement projects. In Tianjin, China, Xingang has been applied and will be the application of plastic panels has reached more than 20 million meters; Lianyungang plans to use this year’s test 20,000 meters, other (such as Shanghai, Ningbo and other places) Soft Foundation
