Description

Technical Field

[0001] This utility model relates to the field of bridge pile foundation drilling technology, and in particular to a bridge pile foundation drilling device. Background Technology

[0002] The construction of cast-in-place piles involves first creating pile holes in the soil manually or mechanically, then placing the reinforcing cage into the pile holes, pouring concrete into the holes to form the pile, and finally casting tie beams or pile caps on top of the piles. Bridge pile foundations are usually in the form of pile groups. If the position of a single pile is misaligned, it will lead to uneven stress on the pile foundation, increasing the risk of overall structural instability. An existing bridge pile foundation drilling device with publication number CN222436304U uses a drill rod jack and a drill bit cleaning mechanism. The drill rod jack controls the raising and lowering of the drill rod for drilling, and the drill bit cleaning mechanism cleans the soil outside the drill rod after drilling. However, this design has a drawback during drilling positioning. Because the drill rod jack is fixed to the drilling machine base, it cannot directly position the drill rod, requiring manual movement of the entire device to adjust and position it. This increases the difficulty of accurate positioning and wastes a significant amount of labor costs. Utility Model Content

[0003] The purpose of this utility model is to provide a bridge pile foundation drilling device in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
