涵管导流在阳霞水库初期导流设计中的应用

The application of culvert diversion in the design of Yang Xia reservoir's initial diversion

涵管导流作为施工导流方式的一种,其自身具有工程规模小、施工工艺简单、施工进度快以及施工风险较低等特点,适用于天然河道狭窄且来流量较小的工程.结合工程特点分时段合理选用涵管导流不仅能够加快施工进度、降低导截流风险,同时能够节约工程投资.文章结合阳霞水库初期导流设计,具体阐述了涵管导流的优缺点及适用条件,旨在为类似工程的设计和施工提供参考.

As a kind of construction diversion method,culvert diversion has its own small-scale projects,the construction process is simple,quick construction progress and construction risk is low.It’s suitable for natural river flow to narrow and small project.Combined with the engineering characteristics of sub period reasonable selection of diversion culvert can not only accelerate the construction progress and reduce the risk of diversion and closure and can save the project investment.According to the design of Yang Xia reservoir’s initial diversion,the paper expounds the advantages and disadvantages of the diversion culvert and the applicable conditions,in order to provide reference for the design and construction of the similar project.
