Tunnel deep hole grouting device

The invention provides a tunnel deep hole grouting device, and belongs to the technical field of tunnel grouting equipment. The tunnel deep hole grouting device comprises a steel flower tube, a hydraulic oil cylinder, a moving mechanism, a grouting core tube, a slurry pumping mechanism and a grouting joint. The tunnel grouting can be conveniently completed, manpower is saved, and he construction difficulty is reduced, and supporting force is provided through the grouting joint and a tunnel lining structure, the uneven stress of the entire device is avoided, and the safety of the construction is conveniently improved. The grouting core tube extends into the steel flower tube, more precise segmented grouting can be achieved while the blockage of the steel flower tube is avoided, and different grouting measures are adopted according to different sections to avoid material waste. 本发明提供了一种隧道深孔注浆装置，属于隧道注浆设备技术领域，包括钢花管、液压油缸、移动机构、注浆芯管、浆液泵送机构和注浆接头。本发明能够方便地完成隧道注浆，节省人力，降低施工难度，并且通过注浆接头与隧道衬砌结构提供支撑力，避免整个装置的受力不均，有利于提高施工的安全性，
