土工管袋技术在湖库底泥脱水中的应用研究

为掌握土工管袋充填过程的变化规律及脱水效果,在疏浚船舶和絮凝剂的配合下,通过对土工管袋首次充填过程及后续充填过程进行实验研究,筛选出了最佳的管袋种类、获得了充填过程管袋高度变化曲线、管袋利用效率、底泥脱水后含水率变化曲线以及充填施工过程中的控制方法等技术指标,为土工管袋的工程化提供了指导,为管袋技术的大规模应用和技术集成化奠定了一定的基础。

Application Research of Geotextile Tube in Lake Sludge Dewatering

To obtain the regulation and the efficiency of dewatering, cooperated with dredging and flocculant, it studied the first filling and subsequent filling of geotextile tubes by experiments, screened out the best tube type and obtained the optimal indexes, such as the change curve of the tube height, utilization efficiency of tube, the moisture content of the dewatered sludge, and the control measures of the filling process. It conducted the engineeriong of geotextile tube and settled the basis of scale application and technology integration.
