高寒地区冬季渠道输水防冻结施工技术

Anti-Freezing Construction Technology for Channel Water Transmissionin Winter in Alpine Areas

渠道输水是跨区域长距离调水最有效的手段,可以将水从水源地输送到缺水地区,满足地区的生态系统需要。但在新疆、西藏等高寒地区,渠道输水在冬季易受冰冻灾害影响,冰盖、冰塞堵塞渠道,减小输水流量,严重影响了过流能力。本文研究出高寒地区冬季渠道输水加热装置,该系统配备发热电缆加热系统,利用电能将电缆加热系统中的发热电缆加热,从而防止渠道中的水结冰,最后通过渠道现场试验,验证装置的可行性。

Channel water transfer is the most effective means of cross-regional long-distance water transfer,which can transport water from water sources to water-scarce areas to meet the ecosystem needs of the region.However,in Xinjiang,Tibet and other alpine regions,channel water transmission in winter is vulnerable to freezing disasters,ice caps,ice plugs blocking channels,reducing water flow,seriously affecting the overflow capacity.In this paper,we have researched a heating device for channel water transmission in winter in alpine areas,which is equipped with a heating cable heating system,and uses electric energy to heat the heating cable in the cable heating system,thus preventing the water in the channel from freezing,and finally verifies the feasibility of the device through a channel field test.
