A, the top for being located at each idle region in profundal zone or phytal zone of sinkage dock pit in the water surface is laid with first layer by predetermined quantity
The empty van group that is formed by connecting of cabinet assembly, the hollow formation chamber of box house, the tank wall of cabinet, which opens up, leads to chamber
Through-hole can bubble through the water column after chamber water-filling, and the vertical projection area of first layer empty van group and profundal zone or phytal zone are each idle
The area in region is mutually fitted；
B, the empty van group that the second layer is formed by connecting by the cabinet assembly of predetermined quantity is laid in first layer empty van group, first layer is empty
Case group is under the gravity of second layer empty van group, and can sink predetermined depth；
C, the total height by the empty van group of each idle overlying regions of step B repetitive operation to profundal zone or phytal zone and profundal zone
Or the leave unused depth in region of phytal zone is mutually fitted or empty van group total height is left unused the depth in region slightly larger than profundal zone or phytal zone
Degree, forms deep water case group or shallow water case group, and via through holes place counterweight so that under deep water case group or shallow water case group to the chamber of cabinet
It is sink to and is contradicted with each idle region bottom wall in profundal zone or phytal zone, complete the deep water in profundal zone or each idle region in phytal zone
The filling of case group or shallow water case group operates, and is finally completed the empty van filling for preventing the idle region siltation in profundal zone or phytal zone from shoaling
Work.
