Zusammenfassung: | To provide a water injection control device for a caisson allowing water injection time loss to be decreased upon suspension of a water injection pump.SOLUTION: A water injection device for a caisson 1 provided with a plurality of areas E1, E2 is provided with: water injection pumps 12, 12, 12, 12 placed corresponding to the plurality of areas E1, E2, respectively, and injecting water into respective areas E1, E2; an auxiliary pump 16 connected selectively to the plurality of areas E1, E2 and injecting water into the connected areas E1, E2; and control means 13 controlling the auxiliary pump 16 so as to inject water into either of the areas E1, E2 with a lower water level. In this way, when water level difference between the areas E1, E2 arises, injection time loss is allowed to be suppressed because of water injection into either of the areas E1, E2 with a lower water level using the auxiliary pump 16 without stopping the water injection pump 12, 12, 12, 12 through controlling the control means 13.SELECTED DRAWING: Figure 1
【課題】注水ポンプの停止に伴う注水時間のロスを削減できるケーソンの注水制御装置を提供する。【解決手段】複数のエリアE1,E2を備えたケーソン1の注水制御装置において、複数のエリアE1,E2に対応してそれぞれ配置され、対応するエリアE1,E2に注水する注水ポンプ12,12,12,12と、複数のエリアE1,E2に選択的に接続され、接続されたエリアE1,E2に注水する補助注水ポンプ16と、補助注水ポンプ16を水位の低いエリアE1,E2に注水するように制御する制御手段13と、を備える。これにより、エリアE1,E2間に水位差が生じたら、制御手段13の制御により、注水ポンプ12,12,12,12を止めることなく、水位の低いエリアE1,E2に補助注水ポンプ16による注水を行うから、注水時間のロスを抑えることができる。【選択図】図1 |
