APPARATUS FOR PLACING FLUIDITY SLURRY TO BOTTOM OF WATER

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for placing fluidity slurry to bottom of water, which is capable of placing slurry adequately to the bottom of water permitting definite placement while maintaining the tip of a cylinder embedded into the slurry already placed without requiring a delicate control of the tip of cylinder even though the fluidity of the slurry to be placed to the bottom of water has a certain dispersion. SOLUTION: A slurry supply device 3 supplies continuously or intermittently fluidity slurry A such as concrete, solidification-treated soil, spoil or the like to the upper end of a slurry flow-down cylinder 1 suspended from water surface to the water bottom surface, and flows down the fluidity slurry A sequentially to the bottom of water inside the fluidity slurry A previously flowed down and deposited on the bottom of water with the lower end of the flow-down cylinder 1 embedded in slurry. The flow-down cylinder 1 comprises a tube pump mechanism 10 comprising an elastic cylindrical portion having a cylindrical body made of a soft material such as rubber or synthetic rubber and a smashing mechanism which pushes and smashes it from the outer peripheral side to radial direction and its pushing and smashing position is sequentially moved downward.
