Blasting weir breaking and flood draining method
The invention relates to the technical field of hydraulic engineering, in particular to a blasting weir breaking and flood draining method. The blasting weir breaking and flood draining method comprises the following steps: 1), when a main project encounters super-standard flood in a construction period, starting an emergency response scheme; 2), injecting water into a foundation pit where a hydraulic structure is built so that a hydraulic structure foundation in the foundation pit is submerged in the water; 3), when the foundation pit is filled with the water to reach the design elevation, blasting a downstream cofferdam so that the water in the cofferdam flows into the foundation pit; and 4), after the water level in the foundation pit is flush with the downstream water level, blasting an upstream cofferdam, and completing weir breaking and flood draining. The blasting weir breaking and flood draining method is extremely simple, the hydraulic structure in the foundation pit can be protected by injecting the water into the foundation pit in advance, damage of the flood to the hydraulic structure is reduced, and the blasting weir breaking and flood draining method has great popularization value.
本发明涉及水利工程技术领域，具体地指一种爆破破堰行洪方法。包括以下步骤：1)、当主体工程在施工期遭遇超标准洪水时，启动应急响应方案；2)、向修筑有水工建筑物的基坑内注水，使基坑内的水工建筑物基础淹没在水中；3)、当基坑内充水达到设计高程时，对下游围堰进行爆破，使围堰内的水流入到基坑内；4)、当基坑内水位与下游水位齐平后，对上游围堰进行爆破，完成破堰行洪。本发明的方法极为简单，通过提前向基坑内注水能够保护基坑内的水工建筑物，降低了洪水对水工建筑物的损害，具有极大的推广价值。
