  河道疏浚公司工程大部分为群众性工程。堤身比较单薄,排水设备,回填土料的质量难以确保。特别是回填土料为淤泥质粘土的,这部分土料长期处在浸水饱和状态。强度弱而自严重,其下滑力较大。当退水时,由于淤泥质粘土的渗透力。而退水后原堤防临水侧的阻滑压力在削减。所以当断水清淤作业时。堤身内的渗流力和自重等主滑动力不断增加,而阻滑水压力在削减,一旦堤身强度不行就易引起渗流失稳。

  施工前要对照设计资料深入工地查询,依照实地状况和机械设备及施工技能做出详细施工组织设计,专业河道清淤对存在问题提早做出处理预案,对软弱地根底要采取机械带水作业,施工时要操控开挖的速度和施工次序,严格操控超挖的数值。将常规的先掏槽后扩坡的施工办法改为由上而下,按梯形断面开挖。对河面较窄,根底土质较好或滑坡后发生影响不大的地段,能够选用断水作业,使用水力机组冲填结合人工开挖施工,这种办法清淤较彻底。作用较好。施工中要注意观察。及时发现堤面开裂、沉陷变形、土质改变状况,作出相应的应急措施。
