一、河道清淤的施工順序要按照自上游到下游的順序進(jìn)行。 First, the construction sequence of dredging should be in accordance with the order from upstream to downstream. 

二、河道清淤在施工前要準(zhǔn)備好卷揚(yáng)機(jī)、立式泥漿泵、泥漿泵浮筒、高壓水泵、水龍帶等設(shè)備，方便將抽出的淤泥及時(shí)處理，以免對周邊環(huán)境造成不必要的影響。 Two. Before construction, the dredging machine, vertical mud pump, mud pump buoy, high pressure water pump, water dragon belt and other equipments should be prepared before the construction. It is convenient to treat the extracted silt in time so as to avoid unnecessary influence on the surrounding environment.
