疏浚平原河道,过去主要是采取人力开挖的方法。随着机械施工队伍的不断壮大,已有不少河道的疏浚,主要借助机械来完成,卫河工程就是其中的一个。卫河疏浚采取机械化施工,是根据以下情况决定的:需清淤的土方工程量较大;土质为粉质壤土和粘土,部分河段还有不少坚硬的胶泥坎;水下方量很大,人工清淤有一定困难,且本区劳动力比较缺乏。从两年来的情况来看,采取机械化施工方法,较之人力施工有较大的优越性。
Dredging plains river, in the past mainly to take the human excavation method. With the continuous growth of mechanical construction team, there have been many river dredging, mainly through the use of machinery to complete the Wei River project is one of them. Wei River dredging mechanized construction is based on the following conditions: a large amount of earthwork to be dredged; soil is silty loam and clay, some sections of the river there are a lot of hard plastic ridge; a large amount of water, Artificial dredging has some difficulties, and the lack of labor in this area. Judging from the situation in the past two years, adopting mechanized construction methods has greater advantages over manpower construction.
