检测地坪注浆加固质量的雷达方法

Assessment of grouting reinforcement for flooring with ground probing radar

探地雷达作是工程物探检测的一项常用技术,现已成熟应用于市政、道路、结构构件的无损检测及验收。为了探究雷达法在地坪注浆加固质量无损检测方面的可行性和准确性。结合工程实例,采用探地雷达对注浆前后地坪分别进行无损检测,并对比分析加固前后的雷达波图,结果表明,雷达法可直观、连续、准确的了解加固后地面的密实情况,弥补目前针对地面注浆加固质量常规检测、验收方法的局限性,为注浆加固工程提供可靠、准确的参考依据。

Combined with engineering instances, used ground probing radar to respectively do non - destructive tests to the floor before and after grouting, and compared and analyzed radar wave charts before and after rein- forcement, the results show that the radar method can be intuitive, continuous and accurate understanding of the dense situation of ground after reinforcement, and make up the limitation of regular testing and inspection meth- ods for ground grouting reinforcement quality, and then provide reliable and accurate references to grouting rein- forcement projects.
