[0033] As described in the background technology, in the tunnel excavation system, the construction process is first cutting, then supporting, and the tunnel support time accounts for 70% of the comprehensive excavation time. Due to the backwardness of the tunnel support equipment and the serious lack of support efficiency, the overall progress of tunnel excavation is seriously restricted. The main reason restricting the tunnel excavation speed of the tunnel boring machine is the low degree of mechanization of the tunnel support using the tunnel boring machine, and the support efficiency lags seriously behind the excavation. The support efficiency of the airborne anchor drilling rig and the single anchor drilling rig supporting the tunnel boring machine is relatively small. The coordination of the drilling rigs on the entire tunnel boring machine working face, the layout of temporary support, the position of personnel, the flow of personnel, the transportation of materials, the escape of personnel, etc., the systematic deficiencies are the fundamental reasons for the backwardness of the excavation support of the entire excavation working face.

The present invention realizes the support operation of the front end of the tunnel boring machine through the first anchor drilling machine, and when the tunnel boring machine is cutting, the support mechanism can be retracted without affecting the cutting operation of the tunnel boring machine and the sight of the tunnel boring machine driver.
