桃江县桃花江水库是一座蓄水7200万m~3,灌溉农田近20万亩的中型水库,养鱼面积4800亩,鱼种池92亩,仅占养鱼面积的1.9％,且绝大部分深度不够,渗漏严重。为此,水库渔场自1990年开始,在总结了浆砌石,三聚磷酸钠,混凝土预制块,xd—103防水复合柔粘和混凝土现浇等多种渠道护坡、防渗效果的基础上,进行了鱼池浆砌石衬三合泥,混凝土预制块衬三合泥和混凝土现浇原浆抹面护坡防渗试验。通过二年的比较,确认混凝土现浇原浆抹面护坡防渗效果最佳。现将其结构设计与施工方法介绍如下: 一、结构设计 1.确定鱼池深度及面积水库修建鱼池是为了解决大水面养殖的鱼种来源。
Taojiang Taohuajiang Reservoir is a medium-sized reservoir with a storage capacity of 72 million m 3 and nearly 200,000 mu of irrigated farmland. The area of fish breeding is 4800 mu and the species pool is 92 mu, accounting for only 1.9% of the fish area, and most of them Inadequate depth, serious leakage. To this end, the reservoir fishery began in 1990, on the basis of summarizing the revetment effect of masonry, sodium tripolyphosphate, concrete prefabricated blocks, xd-103 waterproof flexible composite and concrete pouring and other channels slope protection, The fish pond mortar lining trios mud, concrete prefabricated lining triptych and concrete cast-in-place puree wiping surface slope protection seepage test. Through two years of comparison, confirmed that the concrete pouring plaster surface protection slope seepage control effect best. Now its structure design and construction methods are as follows: First, the structural design 1. Determine the depth and area of fish ponds Reservoir ponds to build fish ponds in order to solve the large surface water sources.
