LIFTING SAND-LIFTING MUD DEVICE OF USING COVERING WATER PASSAGE
PROBLEM TO BE SOLVED: To provide a device, easy in handling for recovering and removing underwater deposit, and capable of sucking underwater deposit for a long distance with the practical concentration.SOLUTION: The water absorption pipe tip is maintained on deposit, a water breaking phenomenon is restrained by adjusting sand absorption capacity by changing a sand absorption port height position of a sand collection pipe part, which is berried in the deposit on the downstream of the water suction pipe and absorbs sand, high or low, a partition is provided in a water passage part having a sand absorption port in the vertical direction, sure starting time water absorption is executed by dividing a suction water passage, a water conveyance water passage is formed in a joint between sand absorption ports of a vertical water passage and a horizontal water passage, and continuity of absorption sand is attained by opening a water channel in a traction clearance in a reinforcement rib for dividing a sand absorption port. Upper water of the deposit is also externally supplied to a sand collecting pipe part sand absorption port, and the suction concentration is improved.SELECTED DRAWING: Figure 1
【課題】 水中沈殿物の回収除去を行なうための取り扱いが容易で、長い距離を実用的濃度で吸引できる装置を提供する。【解決手段】 吸水管先端を沈澱物上に維持し、該吸水管下流の沈殿物中に埋没して吸砂する、集砂管部の吸砂口高さ位置を高く低く変えることで、吸砂能力を調整して水破り現象を抑制し、垂直方向吸砂口を備えた水路部分には仕切りを設けて、吸入水路を分割して確実な始動時吸水を行なわせ、垂直水路、水平水路の吸砂口間つなぎ目には導水水路を形成し、吸砂口を分断する補強リブ等には掃流隙間を開窄して吸砂の連続性を図る。更に、集砂管部吸砂口には沈澱物の上方水を外部給水して、吸入濃度の向上を図る。【選択図】 図１
