在总结化学灌浆经验和工程实践的基础上，研制出HGB-1（2）型化学灌浆设备。该设备利用自作用式原理，油缸和泵体作为执行元件，液压动能作为动力源，配以适当的电器控制系统，采用分体式结构，包括自动调速稳压变量泵和密闭的储浆送浆管路系统两个方面，可进行较长距离的控制并适合各种场地的化学灌浆作业，在三峡F215断层现场灌浆试验施工中取得了良好效果。

On the basis of summarizing the chemical grouting experiences and engineering practices, the chemical grouting equipment marked type HGB-1(2) has been developed. The equipment was designed using self action principle, in which an oil cylinder and a pump were adopted as implement elements, liquid pressure kinetic energy was used as source of dynamic force, and a proper electronic control system was set. The separate structure was employed in the equipment , including an automatic governing, steady pressure and variable discharge pump and a close pipeline system for transferring and storing mortar. The equipment may be controlled for a long distance and can satisfy chemical grouting working in situ. Satisfactory results were obtained using the equipment during the treatment of fault F215 of the Three Gorges.
