[0047] Working principle:

[0048] Before drilling, construction workers use a level to preliminarily adjust the ground plane flatness. Then, the drilling auxiliary device is moved to the position where the cut-off wall needs to be drilled. The drill is aligned with the designed hole position in the horizontal direction by rotating the transverse adjusting rod 25. Then, the device is finely adjusted again through the leveling bolts 4 connected between the transverse sliding rail assembly 2 and the longitudinal sliding rail assembly 3, so that the drill is aligned with the designed hole position on the cut-off wall in the vertical direction. After achieving precise positioning, drilling starts. The drilling depth of the drill is controlled by rotating the longitudinal adjusting rod 35 to achieve rapid drilling. During overseas construction, without re-purchasing a vertical drilling positioning device, an auxiliary device can be quickly assembled using the existing materials of the construction thread, which not only saves time and procurement costs, but also is convenient for operation and construction, improving the construction efficiency.

[0049] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
