Temporary blocking method for dam-crossing box culvert during flood season
The invention discloses a temporary blocking method for a dam-crossing box culvert during a flood season. The method comprises the following steps: S1, calculating seepage pressure P on a plugging area per square meter at a box culvert orifice section, and calculating a box culvert orifice section area S orifice and a hydraulic thrust value F acting on the box culvert orifice; and S2, using bagged soil as a soil plug to resist the hydraulic thrust of the whole box culvert orifice section, according to the hydraulic thrust value F calculated in the step S1, conducting back calculation according to the bagged soil base friction force, and determining the size of the needed soil plug at the box culvert orifice, the area S soil plug needed by the bagged soil to fill the box culvert orifice section and the filling length L soil plug. The flood fighting safety of an unfinished culvert crossing building is ensured under the condition of over-standard heavy water.
本发明公开了一种穿堤箱涵度汛临时封堵方法。它包括：S1：计算箱涵孔口断面处的每平米封堵面积上的渗透压力P，计算箱涵孔口断面面积S孔口以及箱涵孔口上作用的水推力值F；S2：用袋装土作土塞抵挡整个箱涵孔口断面的水推力，根据步骤S1计算的水推力值F按袋装土基底摩擦力反算，确定箱涵孔口处的所需土塞大小，袋装土填塞箱涵孔口断面所需要的面积S土塞和填塞的长度L土填。本发明在超标准大水情况下，保证了未完工穿堤建筑物的度汛安全。
