Flood drainage method for reservoir area type waste slag yard
The invention discloses a flood drainage method for a reservoir area type waste slag yard. The flood drainage method comprises the following steps that before waste slag, firstly a concrete prefabricated pipe is paved at the bottom of a ditch, a masonry retaining wall is built at the upstream end of the prefabricated pipe to form a water collection area, and rainwater is drained to the downstream through the concrete prefabricated pipe embedded under the waste slag yard in a non-flood season. According to the rising speed of the waste slag yard, a temporary flood drainage channel is built on one side of the waste slag yard before the flood season, flood in the flood season is drained downstream through the temporary flood drainage channel arranged on the upper part of the waste slag yard, and the flood in the flood season can be effectively prevented from flushing the waste slag yard. When the temporary flood drainage channel is built, a layer of composite geomembrane is paved at the bottom, and then a reinforced gabion is built on the composite geomembrane. The flood drainage problem of the reservoir area type waste slag field is effectively solved, and the overall stability of the waste slag field is guaranteed; and meanwhile, waste slag block stones can be prevented from being flushed into the diversion tunnel by flood, and diversion safety in the dam construction period is guaranteed.
本发明公开了一种库区型弃渣场的排洪方法，在弃渣前，首先在沟底铺设混凝土预制管，预制管上游端修建浆砌石挡墙，形成集水区域，非汛期雨水通过弃渣场下埋设的混凝土预制管向下游排泄。根据弃渣场上升速率，汛期前在弃渣场一侧修建临时排洪渠，汛期洪水通过弃渣场上部设置的临时排洪渠向下游排泄，能够有效防止汛期洪水冲刷弃渣场。修建临时排洪渠先在底部铺设一层复合土工膜，然后在复合土工膜上砌筑钢筋石笼。本发明有效解决了库区型弃渣场的排洪问题，保证了弃渣场整体稳定，同时能够防止弃渣块石被洪水冲至导流洞内，保证大坝施工期导流安全。
