本文介绍了英国研究人员对特克帕克(Tekpak)-XX、海卓帕克(Hydropak)-20、海卓帕克-30、阿斯卓帕克(Astrapak)-3R、弗拉施帕克(Flashpak)、赛森(Thyssen)和阿克布兰兹(Aquablends)充填材料所形成的充填体强度特性的实验室和现场研究情况。一种简便的充填体强度测试仪器是针穿硬度计。硬度计的试针穿入阻力与充填体的单轴抗压强度相关。充填体强度的现场测试是在从插到充填体内的三根管子中获得的岩芯试样上做的。同时,在充填体的表面也做了穿入试验。现场测试结果表明,充填体的各部分强度不一致,这主要是充填过程中浆体混合不均造成的。
This article describes the British researchers’ performance against Tekpak-XX, Hydropak-20, Hydra Pak-30, Astrapak-3R, Flashpak, Laboratory and field studies of strength characteristics of filling bodies formed by Thyssen and Aquablends fillings. A simple filling body strength test instrument is a needle wear tester. The penetration resistance of the testers of the hardness tester is related to the uniaxial compressive strength of the filling body. Field testing of the strength of the filling body was done on a core sample obtained from three tubes inserted into the filling body. In the meantime, a penetration test was also made on the surface of the filling body. Field test results show that the strength of the various parts of the filling body is inconsistent, which is mainly caused by the uneven mixing of the slurry during the filling process.
