巧溪水库是一座以灌溉为主的中型水库,全灌区有干渠2条,长12.6km,支渠11条,长36.9km。近年来,为了节约灌溉用水,减少渠道水的渗漏问题,有计划地进行了渠道的防渗衬砌。为寻求防渗效果好,造价低廉的衬砌形式和材料,在灌区渠道上采取了几种防渗衬砌措施,以进行试验和比较。在灌区南支二渠道上进行的1000m水泥土U型防渗衬砌渠道,就是其中的一种比较型式。
The Qiao River Reservoir is a medium-sized reservoir mainly of irrigation. There are 2 main channels in the whole irrigation area, with a length of 12.6km and 11 branch channels with a length of 36.9km. In recent years, in order to save irrigation water and reduce the leakage of channel water, a canal lining has been planned in a planned way. In order to seek the lining and materials with good seepage prevention effect and low cost, several kinds of impermeable lining measures have been adopted in the irrigation channels for testing and comparison. One type of comparison is the U-shaped impermeable lining of 1000m cement soil carried on the two channels of the south branch in the irrigation area.
