高岭拦河闸重建工程施工导流模型试验研究

Experimental Study on Construction Diversion of Reconstruction Project of Gaoling River Sluice

由于高岭拦河闸旧闸消力池池深过浅,运行了近50a后受损严重,水闸需重建。设计的重建工程一期施工导流是利用旧水闸左侧11孔旧溢流坝段泄洪,因此一期施工导流风险较大,是重建工程施工导流的关键。通过高岭拦河闸重建工程施工导流模型试验,对一期导流设计方案进行了修改,改善了导流渠的水流流态,试验提出的一期导流防冲加固方案较有效地保证了工程的运行安全。

As a reason of the too shallow old gate of the power pool of Gaoling River Sluice which is running nearly 50 years,the sluice need to be reconstruct. The construction diversion which is the use of the existing sluice on the left side of the 11-hole existing overflow dam discharge,the first stage construction diversion,with greater risk,is the key to the construction diversion. By that experimental study,the diversion design scheme has been modified to improve the flow regime of the diversion canal,and the onestage diversion and anti-flooding scheme proposed by the experiment is more effective in ensuring the safety of the project.
