高含黏(粉)粒土料充填管袋高效脱水技术
Efficient dewatering technology of geotextile tubes filled with high clay ( silt ) particle-content soil
摘要
Abstract
The slow dewatering speed of geotextile tubes filled with high clay ( silt) particle-content soil generally cannot meet the requirement of the limited construction period in the coastal and estuarine areas of China. A preliminary method of actively discharging the surface muddy water in geotubes to improve the dewatering speed was proposed based on the hanging bag tests and settlement tests of filling slurry. The feasibility and actual results of the new dewatering method has been verified by both laboratory model tests and large-scale field model tests. Based on the test results and the field engineering experience, an efficient construction technology that can actively discharge muddy water with alternately filling and discharging techniques to accelerate dewatering speed of geotextile tubes filled with high clay ( silt) particle-content soil was generalized. The specific procedure and construction steps were also provided.关键词
