CAISSON WATER INJECTION CONTROL METHOD AND WATER INJECTION CONTROL SYSTEM
To provide a caisson water injection control method and a water injection control system that can stably submerge a caisson to the water depth immediately before landing with simple water injection control.SOLUTION: Total water injection control, in which the average water level of each block 14 is calculated by averaging the water levels of the compartments 15 in the block 14 when a caisson 10 is in the desired posture, the relative water level difference between the average water levels of each block 14 is stored as a reference water level difference, and water is injected into each block 14 by a water injection pump 2 individually provided in each block 14, and correction control in which the relative water level difference between the average water levels in the blocks 14 is brought closer to the reference water level difference when the relative water level difference between the average water levels in any of the blocks 14 deviates from the reference water level difference by more than a preset allowable value are repeatedly executed until the caisson 10 moves downward to the water depth immediately before landing at a target position B.SELECTED DRAWING: Figure 1
【課題】簡便な注水制御でケーソンを着底する直前の水深まで安定して沈めることができるケーソンの注水制御方法および注水制御システムを提供する。【解決手段】ケーソン１０が所望の姿勢となった時のブロック１４内の隔室１５の水位を平均したそれぞれのブロック１４の平均水位を算出し、それぞれのブロック１４の平均水位どうしの相対的な水位差を基準水位差として記憶し、次いで、それぞれのブロック１４に個別に設けられた注水ポンプ２によりそれぞれのブロック１４に対して注水を行う全注水制御と、いずれかのブロック１４の平均水位どうしの相対的な水位差が基準水位差から予め設定した許容値を超えて乖離した場合に、ブロック１４の平均水位どうしの相対的な水位差を基準水位差に近づける補正制御と、をケーソン１０が目標位置Ｂに着底する直前の水深に下方移動するまで繰り返し実行する。【選択図】図１
