水电站引水建筑物各分部施工相互制约矛盾的处理

Solutions to the Contradictions in the Coustructiou of Water Diversion Structures

水电站工程引水建筑物有引水道、进水口、前池、压力管路等分部工程。这些分部工程施工时相互制约,相互干扰矛盾较为突出,往往影响到整个电站工期,因此水电站工程施工引水建筑物各分部工程施工计划的合理安排是电站工程施工的关键。本文详细介绍了铜山二级水电站工程通过合理调整引水隧洞、进水口、沉沙池、前池、压力管路等分部工程的施工计划解决施工时相互制约、干扰工期矛盾的过程。实践证明,通过引水建筑物施工期的合理调整,在确保工程质量、安全的前提下,缩短工期、节约成本的目标是可以实现的。

The diversion structures of hydropower are consisted of catchwater, intake, forebay, and a pressure pipe, etc. All these structures absolutely constrain and affect each other in the course of diversion structures construction and slow down the period of the whole hydropower construction. Therefore, reasonable arrangement of each part of diversion structure constructions is the key to eusure hydropower construction on schedule. This paper described the resolution process of the contradiction in each parts of water diversion structures constructions by the reasonable adjustments of the diversion tunnel, the intake, the settling basin, the forebay, the pressure piping and other segments of Tongshan II Hydropower Project. It is proved that construction time can be reduced and the cost be saved under the condition of the project quality and safety guarantee through reasonable adjustment of construction period.
