二江泄水闸运行五年来,闸室和护坦产生了磨损。磨损的部位表现为右重左轻,上重下轻,闸室中间重周围轻。分析表明:年输沙量达)80～154)10~4t的推移质泥沙过闸,是造成磨损的主要原因;坝区弯道河势产生的泥沙横向输移和闸区流速分布的不均匀性,是各部位磨损程度不同的关键。随着库水位的升高和大江工程的投产,过闸水沙会明显减少。因此,泄水闸的检修周期可以适当延长,以4～6年为宜。
During the five years since the operation of the Erjiang Sluice Gate, brake chamber and armor have been worn. Worn parts of the performance of right-weight left light, heavy light under the weight of the central lock chamber light. The analysis shows that the annual sediment transport amount is between 80 and 154). The sediment sluice of 10 ~ 4t pumped sediment is the main cause of wear. The horizontal sediment transport and the velocity distribution of sluice Unevenness, the degree of wear is the key to the different parts. With the rise of reservoir water level and the commissioning of the Dajiang Project, the water and sediment flow across the gates will be significantly reduced. Therefore, the sluice gate maintenance period can be extended to 4 to 6 years is appropriate.
