水库大坝白蚁危害及其防治新技术

白蚁是地球上最古老的昆虫之一,至今已生存了2.5亿年。在我国很多地区,白蚁对房屋建筑、水库堤坝、农林生产、通信电缆、交通设施、图书档案等各个领域造成了严重的危害。白蚁危害隐而难察,水库土坝被白蚁掏空坝体是我国南方地区一些中小型水库经常遇到的问题。文章从白蚁危害现状着手,通过对＂复合土工膜＂防治办法和采用灌浆处理法2种方法进行对比后得出结论,在中小型水库中采用灌浆处理法可有效地堵塞白蚁掏洞造成的漏水通道,解决蓄水难题。

Damage of Termite to the Dam of Reservoir and New Prevention and Control Measures

Termite, one of the oldest insect on the earth, has lived for 250 million years to this day. In many parts of Chi- na, termite causes severe damage to buildings, reservoir dam, agricultural production, forestry, communication cable, transportation equipment, books and flies, among other fields. The danger of white ant is hidden and hard to be found. The fact that soil dam reservoir is hollowed out by termite is a common problem facing middle-small reservoirs in southern part of China. In face of this problem, after making comparison between composite geomembrane and grouting as prevention and control measures, the article comes to conclusion that grouting is an effective way to treat leaking tunnel caused by white ant and make water storage possible.
