摘要
注浆就是利用气压、液压或其他动力将具有凝胶性和流动性、并在凝固后具有一定强度和抗渗透性的浆液均匀地压注进被注介质裂隙内进行渗透、扩散及充填的一种工艺,改善注浆介质力学性能,提高介质强度和抗渗性。为在锚杆支护范围内加强支护,研发了一种矿用注浆锚索,与以往的矿用注浆锚索比较,该矿用注浆锚索进一步提高了注浆锚索的使用效果,大大增强了其便捷性。
Grouting is a process that use pressure, hydraulic or other power to evenly press the slurry,which have gel and fluidity, and after solidification has a certain strength and permeability into the injected media crack for infiltration, diffusion and filling, improves mechanical properties of grouting medium, improves the medium strength and impermeability. In order to strengthen the support within the range of bolt support, a kind of grouting anchor cable for mine was developed. Compared with the previous grouting anchor cable for mine, the grouting anchor cable for mine further improves the use effect of grouting anchor cable and greatly enhances its convenience.
