PROBLEM TO BE SOLVED: To provide a dredging device capable of executing dredging work even when an underwater soil surface is weak.SOLUTION: An underwater chamber 1 is a box-shaped rectangular cube, and is opened over the whole surface in a bottom surface part, and has water-bottom traveling four wheels 8 in the bottom part, and executes dredging work by optionally traveling on a water bottom by a plurality of electric underwater screws provided in a four-side surface part of the underwater chamber 1. The underwater chamber 1 discharges sludge and sediment deposited on a water bottom onto the ground by sucking sludge water by a pump installed in an outer wall surface part by agitating on the inside of the underwater chamber 1 by jet-injecting high pressure water toward the water bottom from an injection nozzle when traveling on the water bottom, by installing a plurality of high pressure water injection nozzles in four-side parts of an inside bottom surface part. The dredging work is executed by making a support deck M accompany-travel with the underwater chamber 1 while monitoring a state of the water bottom by an underwater camera provided in a front side surface outer part of a box by a monitoring board provided on the support deck M provided on the water.SELECTED DRAWING: Figure 1
【課題】水中土面が軟弱な場合でも浚渫作業を行うことができる浚渫装置を提供する。【解決手段】水中チャンバー１はボックス形状の長方立方体で、底面部が全面開放され、底部には水底走行用の四車輪８を備え、水中チャンバー１の四側面部位に備えた複数の電動水中スクリュウにより水底を任意に走行して浚渫作業を行う。水中チャンバー１は、内部の底面部の四辺部位には複数の高圧水噴射ノズルが取付けられて居り、水底を走行中に噴射ノズルより高圧水を水底に向かってジェット噴射させて水低に堆積しているヘドロ、土砂等を水中チャンバー１内部で撹拌させて外壁面部位に取付られているポンプで汚泥水を吸引して地上に排出する。浚渫作業は、水上に設けられた支援デッキＭに備えられた監視盤でボックスの前側面外部位に備えられている水中カメラで水底の状況をモニタリングしながら支援デッキＭを水中チャンバー１と併走させて行う。【選択図】図１
