白蚁是世界五个虫害之一,危害对象广、范围大,造成的经济损失亦巨,而堤坝遭受白蚁危害,威胁工程安全,更事关重大。危害我省土堤坝的主要是黑翅土白蚁,它在堤坝内可筑成巨大的主巢(直径达一米以上)和数量众多的副巢,其蚁道四通八达,有的贯穿堤坝内外坡形成通道。主蚁道直径达7厘米左右,一旦遭遇水位上涨,贯穿内外坡面的蚁道即成漏水通道,造成背水坡坡面散浸、管涌等险情,甚之发生决堤垮坝的重大灾害。故有“千里金堤,溃于蚁穴”之说。当前各地水利部门,为保证堤坝防洪安全,积极开展堤坝土栖白蚁的防治工 Termite is one of the five pests in the world. It has a wide range of hazards and a huge economic loss. Termites are endangered by termites and threaten the safety of construction. More importantly, termites are one of the five pests in the world. Endanger the dam of our province is mainly the black-winged termites, it can be built within the dam of a large main nest (up to a meter in diameter) and a large number of vice nest, the ant extends in all directions, and some inside and outside the dike formation aisle. The main ants reach about 7 centimeters in diameter. Once the water level rises, the ants that go through the inner and outer slopes become leaky passages, causing the danger of flood and piping on the back slope. Therefore, “thousands of miles Jindi, collapse in the ant nest,” said. At present, water conservancy departments across the country, in order to ensure the safety of dams flood control, and actively carry out prevention and treatment of dams termites termites
