钻孔电磁波技术在水泥浆灌注质量检测中的应用

在江苏省某濒江工地,为了对水泥浆灌注质量进行评价,利用钻孔电磁波开展井间跨孔检测,获得了水泥浆灌注距离,土洞、溶洞和疏松体是否被水泥浆充满,灌注是否密实均匀等信息.检测结果证明该方法可以评价一定面积范围内的水泥浆灌注质量.

Quality test of cement slurry grouting in limestone foundation

In limestone area,groundwater runoff,soil cave,loose body and well-developed karst caves often result in ground collapse so as to influence the safety of ground building. Cement slurry grouting in limestone foundation is an economical,reasonable and effec-tive method to prevent ground collapse. In order to get various kinds of information,such as the distance of cement slurry grouting,and the conditions as to whether soil cave,loose body and karst cave are filled with cement slurry and whether grouting is dense and uni-form,researchers can use borehole electromagnetic wave to carry out cross-hole inspection for grouting quality of cement slurry.
