摘要
结合乌江构皮滩水电站工程进行了无盖重固结灌浆现场试验,通过对建基面裂隙采用了高强、快硬嵌封堵漏材料进行封堵,从而保证了固结灌浆的压力,实现了真正意义上的无盖重固结灌浆,具有一定的技术创新性。无盖重固结灌浆已经成功应用于构皮滩水电站大坝的基础处理,不但效果良好,而且有效缩短了工期,值得在同类工程中推广应用。
According to the field test of consolidation grouting without cover weight in light of Goupitan Hydropower Station project, sealing the fissures of workfaee with high - strength and fast hardening materials, thus the pressure of consolidation grouting was ensured, the consolidation grouting without cover weight had been realized truly. It has certain technical innovation. The consolidation grouting without cover weight had been applied to dam founda- tion treatment of Goupitan Hydropower Station. Not only was the effect well but also the construction period was shortened. This was worth to popularize to similar projects.
