利用泥浆泵进行渠道开挖,所用机械简单、人员极少,而且开挖速度快、效率高。但是在施工中,因水枪和泥浆流的冲刷,施工边线极难控制,造成后期清理弃土、填土过多,费时而且费工。笔者在多年的施工中,不断地摸索,总结出先超后淤的施工方法(简称“先超后淤法”),能有效地克服泥浆泵施工的不足,取得了良好的经济效益。

The use of mud pump channel excavation, the use of machinery is simple, very few staff, and excavation speed, high efficiency. However, during construction, due to the erosion of the water gun and the mud flow, the construction sideline is extremely difficult to control, resulting in the late disposal of spoil, excessive filling, time-consuming and labor-intensive. The author in many years of construction, continue to explore, summed up the first super-post-silt construction method (referred to as “first ultra-post silt method”), can effectively overcome the lack of mud pump construction, and achieved good economic returns.
