Background
At present, as underground tunnels are more and more constructed in national engineering construction, development machines are widely adopted in tunnel construction due to the characteristics of high efficiency, environmental protection and safety. Because the hydraulic tunnel is generally buried deeply and the tunnel body is positioned below the ground water level, in order to ensure the safety of the lining structure, drain holes are needed to be arranged in the arch part structure of the lining after the lining construction is finished, the ground water in the rock body outside the lining structure of the tunnel is led into the tunnel, and the lining structure is prevented from being damaged due to too large water pressure of the ground water; however, under the influence of rail transportation and a slag belt conveyor, the construction of the drain hole of the common tunnel is organized after the tunneling and the lining of the tunnel are completely finished. Because the drain hole can not be constructed in time because of not having the construction condition for a long time after tunnel lining construction is accomplished, consequently, cause lining cutting outside water pressure very high, quality problems such as crack appear in the lining, cause adverse effect to lining structure safety. Meanwhile, the construction is organized again after the interference is reduced by the drain holes, so that the project construction period is delayed seriously. And the drain holes are perpendicular to the inner surface of the lining, and the hole diameter is large, so that a geological drilling machine is required for construction. Because the drain hole is perpendicular to the lining hole wall, the direction of a drill rod must pass through the center of the tunnel when the drilling equipment works, the drilling equipment and rail transportation have space sharing and mutual interference, and potential safety hazards exist during the operation.
