Resource constraint bottleneck is significant.Bagged sand and jackstone are the mainstream banking materials of coastal water transport, hydraulic engineering at present, wherein bag
Sand loading fill adds up more than 1000km at home.But make ground engineering on a large scale in recent years and cause sand source in short supply, it cuts into a mountain and stone is taken also to satisfy
It tastes and destroys denouncing for ecology.Domestic each research unit is all developing new substitute technology, and wherein mud fill technology is exactly main
Striving direction, nearby draw materials, economical and efficient.
Existing mud fill is divided into two classes, and the first kind is slush mud bag fill；Second class is that curing agent is added
Mud fill.Currently, first kind slush technique is: first adding water pulping with high pressure water, conveying concentration of hydraulic mixture is low, generally
10-15% makes mud fluidization, then bag is conveyed and filled with centrifugal pump, completes a soil engineering bag and charge generally be repeated 3 times, and
And mud draining is slow in soil engineering bag body after filling, construction period is longer；Wherein the second class construction technology is similar with the first kind, and
Add curing agent during filling, mud and curing agent slurry voluntarily mixed in the duct, into bag body after solidify, due to
Stowing pulp concentration is lower, and mixture homogeneity can not control, mix the mud of curing agent during consolidation draining, solidify
Agent number of dropouts is larger, solidifies the problems such as uneven, and cost is also higher, and water content is still higher after consolidation, and due to curing agent
Incorporation it is uneven and cause levee body form after bearing capacity it is uneven.
To solve the above-mentioned problems, we are made that a series of improvement.
