The invention relates to the technical field of grouting equipment and particularly relates to a grouting head assembly, a using method of the grouting head assembly and a pavement patching grouting process. The grouting head assembly comprises a grouting head body and an elastic expansion component, wherein the elastic expansion component is arranged outside the grouting head body; the elastic expansion component is of a hollow structure with the changeable internal volume; the elastic expansion member is formed with an inlet end for connecting a pressure source. The grouting head assembly isadvantaged in that due to the fact that the elastic expansion component is additionally arranged outside the grouting head body, hydraulic oil and the like can be filled in the grouting head body toenable the grouting head body to expand, a drilled hole is blocked, the effect of preventing grout leakage is achieved, the grouting head body is not prone to shaking, and stable grouting pressure isguaranteed.
本申请涉及注浆设备技术领域，尤其是涉及一种注浆头组件、注浆头组件的使用方法及路面修补注浆工艺，注浆头组件包括：注浆头本体以及弹性膨胀构件；其中，弹性膨胀构件设置于注浆头本体的外部；弹性膨胀构件具有内部容积能够变化的中空结构；弹性膨胀构件形成有用于连接压力源的进口端。可见，由于在注浆头本体的外部增设了弹性膨胀构件，其内部可充装液压油等，使其膨胀，进而封堵住钻孔，起到防止漏浆的作用，而且使得注浆头本体不易晃动，保证注浆压力稳定。
