[0002] Chinese patent document CN217001831U discloses an anti-deviation device for geological exploration drilling, relating to the field of geological exploration technology. It addresses the problem that existing anti-deviation devices suffer from low friction on soft soil, reducing stability during use. The device includes a base plate; a rectangular sliding cylinder is welded to both the front and rear ends of the base plate, and two extension rods are symmetrically connected inside each rectangular sliding cylinder. Each extension rod has a connecting block at its outer end, and each connecting block is connected to an adjusting support. By rotating the support assembly, if the soil at the exploration location is soft, rotating the second pad to the lower part allows the anti-slip insert at the bottom of the second pad to be inserted into the soft soil, thus increasing the friction on soft soil and improving the stability of the anti-deviation device during use.
[0003] When using the aforementioned anti-deviation device for geological exploration drilling, workers need to manually insert each set of rods into the ground in sequence. If the ground is relatively compacted, the operation is troublesome and laborious, greatly increasing the workload of the workers. Utility Model Content

If the ground is relatively compacted, the operation is more troublesome and laborious, which greatly increases the workload of the staff.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling anti-deviation structure for geotechnical engineering exploration, comprising a hollow block, an anti-deviation component, and a guiding component. The anti-deviation component is disposed below the hollow block and includes a bidirectional threaded rod, a sliding block, a connecting block, a hinge block, and a movable rod.

This ensures that the inner wall of the guide block can fit the drill rod and prevent the drill rod from shifting.
[0008] Preferably, a set of auxiliary handles is fixedly installed on the front and rear sides of the guide block, respectively.
[0009] Preferably, multiple sets of casters are fixedly installed at the bottom of the hollow block.
[0010] Preferably, the top of the hollow block has a through-hole that runs vertically through the rod, and the through-hole is connected to the interior of the guide block.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
