无损探测修复技术在白龟山水库堤坝白蚁防治中的应用

Application of nondestructive detection and repair technology in prevention and control of termite in the dam of Baiguishan Reservoir

白龟山水库顺河坝白蚁危害严重。为准确、快捷、方便地探查、修复蚁巢,采用探地雷达对堤坝可疑区域进行探测,定位异常点。在不开挖的情况下,根据探得的蚁巢定位,将含防白蚁药剂的浆料,使用压力灌浆机灌注至蚁巢和蚁路中,杀灭白蚁的同时,充填空洞,修复坝身。该技术可供其他类似白蚁防治工程借鉴。

Termite disaster is serious in Shunhe Dam of Baiguishan Reservoir. GPR is used for detecting the suspicious areas of the dam and locating abnormal points in order to detect and repair the ant nest accurately, quickly and conveniently. Paste containing termite medicament is filled into termite nest and termite way by using pressure grouting machine without excavation according to the detected termite nest positioning. Empty holes are filled,and the dam is repaired during termite killing. The technology can be used as reference for other similar termite control projects.
