Document Type and Number:
Japanese Patent JP3240391
Kind Code:
B2
Abstract:
PURPOSE: To make a large spoil bank unnecessary by a method wherein sand deposited on the bottom of a dam reservoir is collected and is formed into blocks, being mixed with solidifying agent in small bonding strength, and after that the blocks are arranged in the area on the downstream side of the dam.
CONSTITUTION: Earth and sand 2 deposited on the bottom of a reservoir of a dam 1 is collected by employing a dredger 3, and is carried through a pipe 4 to a forming facility 5. Then, the sand is mixed with solidifying agent in small bonding strength at the forming facility 5, and thereby blocks 6 that are easily collapsed by penetration action of water or impact force of flow in a river are formed.
