NEXT GENERATION HIGH VACUUM CONSOLIDATION SYSTEM AND VACUUM BOILING CONSOLIDATION METHOD, VACUUM CONSOLIDATION DREDGING METHOD, PRESSURE INCREASE/DECREASE TANK, AND VERTICAL DRAIN
To solve the problem that a vacuum boiling consolidation method enabling rapid consolidation requires rapid decompression change, a next generation high vacuum consolidation system enabling the rapid decompression change needs to be constructed, but the rapid decompression by a vacuum pump is impossible in actual foundation.SOLUTION: A new vacuum device is a pressure increase/decrease tank based on Boyle's law. Sealability of a gap of vertically moving pistons is solved by a cylindrical seal surrounding an outer peripheral surface of a cylindrical piston. The method is designed so that contact pressure to an outer cylinder from inside the cylindrical piston through the cylindrical seal becomes larger than fluid pressure acting on the gap. The system causes vacuum boiling due to rapid decompression change by combining a cold trap connected with a heat supply device, the pressure increase/decrease tank that facilitates generation of high vacuum, and a vacuum pump that facilitates adjustment of vacuum pressure.SELECTED DRAWING: Figure 3
【課題】急速圧密となる真空沸騰圧密工法は、急激な減圧変化が必須条件である。これを可能とする次世代高真空圧密システムの構築が必要である。しかし、真空ポンプによる急激な減圧は実際の地盤では無理である。【解決手段】新しい真空装置はボイルの法則に基づく圧力増減タンクである。上下動するピストンの隙間の密封性は、筒型ピストンの外周面を包み込む筒状シールで解決した。その方法は隙間に作用する流体圧力よりも筒状シールを介した筒型ピストン内部から外筒への接触圧力が大きくなるように設計する。当該システムは熱供給装置を連結させたコールドトラップと高真空の発生が容易な圧力増減タンクと真空圧の調整が容易な真空ポンプを組み合わせ、急激な減圧変化で真空沸騰を起こすことで真空沸騰圧密工法を実現した。【選択図】図３
