冬季是江河枯水期,而且每年又有度春汛抗大汛的要求,这决定了水电建设中搞冬季施工是必不可少的。由于冬季施工难度大,超耗大,及现行一些管理办法不尽合理,使冬季施工的企业费用超支严重,效益受损。所以,冬季施工项目需严格控制,同时也要有一套科学的定额管理办法,对高寒地区的冬季施工进行实际消耗分析和定额测定,从而予以适当补偿。黑龙江莲花水电站地处严寒地区,他是在改革后的新机制条件下建设的,以大量实践资料表明,冬季施工超耗严重。
Winter is the river dry season, but also the annual spring flood resistance flood season requirements, which determines the construction of hydropower winter construction is essential. Due to the difficulty in construction in winter and excessive consumption, some existing management methods are not reasonable, which makes the cost of enterprises in winter construction serious over-expenditure and impaired benefits. Therefore, the construction projects in winter need to be strictly controlled, and a set of scientific quota management methods should also be adopted at the same time to conduct actual consumption analysis and quota determination of the winter construction in alpine regions so as to make appropriate compensation. Heilongjiang Lotus Hydropower Station is located in severe cold areas, he is in the reform of the new mechanism under the conditions of construction, with a large number of practical data show that the construction of the winter over-consumption.
