Large filling bag ecological embankment and revetment building method for river lake channel
The invention provides a large filling bag ecological embankment and revetment building method for a river lake channel. The method comprises the steps that (1), on the basis of cleaning and leveling, an embankment structure is filled with cleaned river lake bottom mud layer by layer through the large filling bag technology until the embankment structure reaches up to a designed elevation of the embankment top and the height of 0.5-1 m beyond the designed elevation is reserved through filling construction; (2), the cleaned river lake bottom mud is filled through a land pump, or special complete equipment and corresponding construction technologies are adopted to directly conduct mechanical paving and filling, and then the filled cleaned river lake bottom mud is sewn into bags; and (3), filling soil materials of the large geotextile filling bag embankment structure are taken from local resources, the bottom mud obtained through river lake regulation and channel excavation and cleaning is used as the filling soil materials, the initial water content of the filling soil materials is controlled within the range from 50%-80%, and the large filling bag embankment structure which is layered appropriately is adopted according to the practical situation. According to the method, the design is reasonable, the process is simple, construction is easy, operation is convenient, cost is low, popularization is easy, the ecological functions are good, and the method is applicable to ecological management and ecological channel construction of river lakes in soft soil areas.
