Title: Vacuum consolidation method, vacuum consolidation dredge method, vacuum consolidation test system, vertical drain driving machine, and air tight loading caisson
Inventor: KONDO MASAYOSHI
IPC: E02D3/10
Filed: 2021-03-24
Abstract: To solve a problem such that an acute consolidation-promoting effect of a vacuum boiling consolidation method is not sufficiently utilized in its feature because of unclear mechanism, for example, in a sludge ground on the sea bed or the like, or an enlarged air-tight loading caisson used for the vacuum boiling consolidation method for the seabed ground and a vacuum consolidation dredge method causes the excessive enlargement of an exclusive work ship and drastic increase in a construction cost.SOLUTION: An acute consolidation-promoting effect is found out to be a fine bubble effect generated in interstitial water by reduced-pressure boiling. A required amount of fine bubbles varies depending on a cation exchange capacity in the ground, and the amount of fine bubbles depends on a boiling time. Therefore, an effective boiling time is calculated by a vacuum consolidation test and is incorporated into a vacuum consolidation process. If the required amount of fine bubbles cannot be secured through short time boiling, fine bubbles are produced by a generator so as to replenish the shortage. Also, an enlarged air-tight loading caisson adopts a self-submerging type air-tight loading caisson without using an exclusive work ship so that a construction cost can be drastically reduced and a public construction cost on a coastal sea area can be reduced.SELECTED DRAWING: Figure 7
