Advanced grouting equipment and advanced grouting method
According to the technical scheme, the advanced grouting equipment and the advanced grouting method are characterized in that the advanced grouting method comprises the specific steps that an advanced grouting hole is formed in a shield tunneling machine; a drill rod of the advanced drilling machine is adjusted by means of a pipe piece erector and a pitching air cylinder of the advanced grouting equipment, so that the drill rod is inserted into the advanced grouting hole; the advanced drilling machine is controlled to drill holes to the front of a shield tunneling machine cutter head, and grouting operation is conducted; in the drilling process, changes of parameters such as rotating pressure, propulsive force and impact pressure are observed all the time, and shutdown inspection is conducted immediately when abnormal phenomena are found; and a drill rod of the advanced drilling machine is controlled to retreat from the current advanced grouting hole, and the advanced grouting hole is replaced until the advanced drilling machine completes advanced grouting operation in all the advanced grouting holes. According to the method, changes of parameters such as the rotating pressure, the propulsive force and the impact pressure serve as the basis for judging the working state of the drill rod by field control personnel, the requirement of advanced grouting operation for the professional quality of the field control personnel is lowered, and rapid propulsion of shield construction is assisted.
本发明公开了一种超前注浆设备及超前注浆方法，其技术方案要点在于超前注浆方法，具体步骤为在盾构机上设置超前注浆孔；借助管片拼装机和超前注浆设备的俯仰气缸调整超前钻机的钻杆，使其插入超前注浆孔中；控制超前钻机钻孔至盾构机刀盘前，并进行注浆作业；钻孔过程中，时刻观察旋转压力、推进力、冲击压力等参数的变化，发现异常现象应立即停机检查；控制超前钻机的钻杆退出当前超前注浆孔，更换超前注浆孔，直至超前钻机在所有超前注浆孔中均完成超前注浆作业。本发明将旋转压力、推进力、冲击压力参数的变化，作为现场控制人员评判钻杆工作状态的依据，降低了超前注浆作业对现场控制人员专业素质的要求，助力盾构施工快速推进。
