Problems solved by technology

[0004] The invention relates to a high-efficiency and fast separated direct-connected vacuum preloading soft foundation treatment method, which overcomes the defects of using a large number of medium-coarse sand cushions in conventional vacuum preloading and consuming a large amount of resources, and reduces the vacuum degree in the original process. The transmission loss in the coarse sand pad shortens the vacuum transmission path; the working principle of the traditional jet vacuum pump is improved, and the water-gas separation device is used to separate the water and gas, which accelerates the directional flow of the water body, improves the way to maintain the vacuum pressure, and improves the Vacuum efficiency saves a lot of electric energy and corresponding power distribution facilities; for the vertical drainage body, the filament fiber non-woven filter membrane is used to increase the equivalent pore size of the filter membrane

Abstract

The invention provides an efficient quick method for treating separated directly-connected vacuum preloaded foundation. The efficient quick method mainly includes: paving knitted cloth or geotextile on a soft foundation to be treated; arranging longitudinal plastic drainers; mounting a vacuum delivering pipe network; arranging water and steam separators; paving a sealing film; mounting a vacuum control room; and vacuumizing. In the efficient quick method, a medium-coarse sand cushion layer in a routine vacuum preloading method is replaced, and a path for delivering vacuum is shortened. Meanwhile, due to the arrangement of the water and steam separators, an air exhausting theory in the conventional vacuum preloading method is changed, curing time is shortened, curing effect is improved, and quickness, efficiency, energy-conservation and environment-friendliness of a construction process are realized.

Description

technical field [0001] The invention relates to a foundation treatment technology, in particular to a high-efficiency and fast separation-type direct-connection vacuum preloading foundation treatment method, which is mainly applicable to soft soil or ultra-soft soil foundation, and belongs to the field of geotechnical engineering. Background technique [0002] With the large-scale land reclamation projects and coastal zone development projects in my country's coastal ports are booming. The coasts of Dalian, Tianjin, Jiangsu, Zhejiang, Guangdong, Guangxi and Hainan are all reclaiming land from the sea on a large scale. These areas are mostly silty soft soils with high water content and high compressibility. my country's rapidly developing economic construction urgently needs fast, efficient, energy-saving and environmentally friendly soft ground treatment technology. The vacuum preloading technology developed in the mid-1980s has been developed and continuously improved for...
