In general, the drilling and blasting method is implemented on the premise that the excavation of a heading machine is difficult to realize, and the tunneling method of the hard rock roadway (tunnel) meets the construction conditions of the drilling and blasting method. However, due to various disadvantages of the drilling and blasting method, a new method for tunneling by adopting hydraulic fracturing combined with a tunneling machine is provided at present, wherein a hard rock lane (tunnel) is drilled and injected with high-pressure water, when the stress around the drilled hole reaches the cracking condition of surrounding rocks, a crack network is formed in the hard rocks, and the effect of destroying the integrity and strength of rock masses in the hard rock lane (tunnel) is achieved, so that the strength of the rock masses in the hard rock lane (tunnel) reaches the degree of continuous cutting and tunneling by using the tunneling machine.
The new method for tunneling the hard rock roadway (tunnel) by adopting the hydraulic fracturing technology still has certain problems, the application of the new tunneling method mainly depends on a drilling machine, hydraulic fracturing equipment and a tunneling machine, in the construction process, according to the drilling design of hydraulic fracturing, the drilling machine is used for drilling the hard rock roadway (tunnel), the drilling machine is moved away after the drilling is finished, then the hydraulic fracturing equipment is moved to the tunneling working face, the hydraulic fracturing is carried out on the rock mass in the working face, and after the fracturing is finished, the hydraulic fracturing equipment is moved away and the tunneling machine is started to the tunneling working face. The repeated movement of the equipment is caused by the narrow space of the tunneling working face, and the limitation of the space only allows one set of equipment to work, so that the labor intensity of workers is improved, the preparation time before tunneling is prolonged, and the tunneling efficiency is influenced.

In the process of underground roadway tunneling and tunnel excavation, the engineering progress is directly influenced by the tunneling efficiency, and an effective mode for improving the tunneling efficiency is to improve the tunneling technology and equipment.
Generally, the following problems are mostly existed in the traditional equipment during the hard rock roadway (tunnel) tunneling process: 1) the blasting discontinuous tunneling mode can generate strong disturbance to surrounding rocks and the earth surface of a roadway (tunnel), and the blasting can generate potential safety hazards and generate harmful gas to threaten the safety of workers; 2) after the blast occurs, long-time ventilation and harmful gas emission are needed, and the tunneling efficiency is affected; 3) the space of a driving working surface is limited, a drilling machine, hydraulic fracturing equipment and a driving machine cannot be arranged at the working surface at the same time, after one equipment finishes working, workers need to move the equipment away and then replace the next equipment for working, and the working efficiency is influenced; 4) the maneuverability of drilling rigs and hydraulic fracturing equipment often depends on the handling of workers, resulting in poor maneuverability.
Therefore, how to improve and optimize the hard rock roadway (tunnel) tunneling construction equipment to achieve the purpose of drilling-pressing-tunneling integration becomes a technical problem to be solved urgently by technical personnel in the field.
