长春地区干旱少雨,市内严重缺水,多数居民开始饮用井水,一些工厂、车间停产。因此,从一九七六年冬开始突击修建了工农渠引水工程。自石头口门水库提水(饮马河水源),将水引入“五一”水库,又在“五一”水库岸边新建一座提水流量为3米~3/秒的泵站,再通过28.5公里的新建土渠将水送至长春市内。其中八公里长的填方渠道(包括半填方)山冻土和暖土混合填成,没有夯实。为了防止放水冻融后自然塌陷以及减少渗漏,我们采用了塑料薄膜铺设渠道。运用五年来,情况良好。
In Changchun, where there is arid and no rain, there is a serious water shortage in the city. Most residents start to drink well water and some factories and workshops are discontinued. Therefore, from the winter of 1976, the workers, peasant and diversion works were assaulted and constructed. From Shitoukoumen Reservoir to raise water (Yinmahe water source), the water will be introduced into the “May 1” reservoir, and a new pump station with water flow of 3m ~ 3 / s will be built on the shore of “May 1” reservoir. 28.5 kilometers of new canal will be sent to Changchun City. Among them, eight kilometers of fill channels (including semi-fillings) are filled with mixed frozen earth and warm earth and have not been compacted. In order to prevent natural collapsing after the freeze-thaw and reduce leakage, we adopted a plastic film laying channel. After five years of use, the situation is good.
