Sand is internal to the dry burnt-in sand bag in upper strata, and the dry burnt-in sand bag body in upper strata is sewed it up with portable sewing machine after sand is full, finally washed by water closely knit；
Thickness deficiency or during local eminence, should artificial stop-off leveling in time or with the leveling of high-pressure water pipe water-filling；
(5), after the completion of the body of weir, laying protection geotextiles, after the completion of the bath of top layer sand pocket is closely knit, sun-proof geotechnique is laid in time
Cloth, wrap up whole sand pocket cofferdam.
The present invention has the advantages and positive effects of：The present invention efficiently solves higher in material shortage, cost of transportation
Etc. the problem of regional hydraulic reclamation cofferdam construction, can gather materials on the spot, it is easy for construction, it is loose to packing material Particle size requirements, can quick shape
Into cofferdam, construction cost is greatly reduced, the advantages that accelerating construction speed.The method is fully demonstrated by engineering construction example
Its exploitativeness and economical.
