新舞沟重点山洪沟防治方案比选与设计

The Comparison and Design of the Prevention and Control Scheme for Key Mountain Flood Gullies in Xinwugou

文章以务川县浞水镇新舞沟重点山洪沟防治工程为研究对象,通过对洪水情况和现有排洪能力的分析,提出了务川县浞水镇新舞沟重点山洪沟防治工程实施方案。该方案通过新建排洪隧洞,将新舞沟上游洪水引排入浞水河集镇下游主河道内,从而解决集镇的防洪问题。经过综合比较,确定方案二为最佳方案,具有较为合理的隧洞长度和进出口高差,其施工难度相对较低。实施该方案能够有效排洪,提升集镇河段的防洪能力,保障居民的生命财产安全。

The article focuses on the research of the prevention and control project of Xinwugou Key Mountain Flood Ditch in Zhuoshui Town,Wuchuan County.The proposed implementation plan of the Xinwugou key mountain flood ditch prevention and control project in Zhuoshui Town,Wuchuan County is formulated based on an analysis of the flood situation and existing flood discharge capacity.The flood control problem of the town is effectively addressed through construction of a new flood discharge tunnel to divert the upstream flood from Xinwugou into the downstream main river channel of Zhushui River Town.After comprehensive comparison,Plan Two has been determined as the optimal choice due to its relatively reasonable tunnel length,as well as its inlet and outlet height difference,along with its ccomparatively low construction difficulty.The implementation of this plan can effectively mitigate floods,enhance the flood control capacity of the town's river section,and ensure the safety of residents'lives and property.
