[0001] The invention relates to the technical field of tunnel construction, in particular to a telescopic multi-head water-grinding drilling rig for tunnel construction. Background Art

[0002] Water-grinding drilling construction is a new type of construction method. It is often used in construction environments where blasting cannot be used, where there is limited space, or where there are important equipment and facilities nearby. It cannot be replaced in some special working conditions because of its high site applicability, low environmental impact, small vibration and disturbance to surrounding buildings, no restrictions on the supply of pyrotechnics, simple operation, stable progress, and good safety.

[0003] At present, most of the existing water-milling drills are fixed on top of the bracket when in use, and the use position of the drill is extended and adjusted by moving the bracket. This easily leads to the need to frequently adjust the drill bracket when the device is in use, and the bracket needs to be re-fixed after the adjustment, which is cumbersome to use and reduces the efficiency of use.
