Construction method for three-stay mudflat earthwork diker

The invention discloses a construction method for a three-stay mudflat earthwork diker, which relates to construction of river digging and diking engineering. The method comprises river digging and diking integrated construction processes of positioning and moving of a diker, walking of the diker on a mudflat, digging, transportation and filling of an earthwork and construction processes of dehydration, drainage and soil wall support. The method realizes synchronization of river digging and filling, puts floating water aside for two purposes, and has high construction efficiency and obvious economic benefit. The method has the advantages of low soil disturbance, high strength, quick solidification, low formed slope ratio, good dyke stability and strong environment adaptability. The methodis suitable for the earthwork engineering in a conveying distance of within 150 meters under the environment conditions such as shoal, marsh, shallow water and the like.
