“千里之堤,溃于蚁穴”.我国南方诸省,土栖白蚁(主要是黑翅土白蚁,水利部门惯称为堤坝白蚁)对水利工程土工建筑物危害严重.据前些年不完全统计,我省的江河堤防及水库主坝受土栖白蚁危害的在80%以上.由于土栖白蚁在堤坝内部营巢筑洞,若不及时除治,幼龄巢发展为成年巢后,随着群体的扩大,蚁道纵横交错,有些甚至贯穿堤坝(以堤防和山塘为多),当水位上涨时,浸润线提高后,蚁道充水,渗径缩短,因而产生管涌、流土,甚至跌窝、塌坡等险象,若抢护不及时,便造成堤坝溃决,使人民生命财产遭受重大损失.为此,必须积极开展专业与群众性相结合的防治堤坝白蚁工作,力争早日消除蚁患,确保堤坝安全,为促进四化建设作出应有的贡献.
“Thousands of embankments, collapse in the nest.” In southern provinces, soil termites termites (mainly black-winged termites, water conservancy departments dams termite dams) on the hydraulic engineering geotechnical buildings serious harm.According to the previous years is not complete Statistics show that in our province, the embankments of the rivers and main dams of the reservoir are harmed by soil-living termites by more than 80%. Because soil-living termites nest and build holes in the dams, if the young nests develop into adult nests, When the water level goes up, the infiltration line will increase, and then the ant tunnel will be filled with water and the seepage will be shortened. As a result, piping, soil and water flow will be generated, Even drop nest, slope collapse and other dangers, if the protection is not timely, they will cause the dam to collapse and make the people’s lives and property suffer a great loss.To this end, we must actively carry out the professional and mass combination of prevention and control dams termite work, and strive to eliminate ants as soon as possible Suffering, to ensure the safety of levees, to make due contributions to promoting the four modernizations.
