Description

Technical Field

[0001] The utility model belongs to the technical field of rock and soil exploration, and more specifically, particularly relates to a rock and soil directional drilling device. Background Art

[0002] Geotechnical investigation is the use of testing means and methods to investigate and study the site, and analyze and determine the structure, formation age, cause, and soil type of the foundation rock and soil layers. Geotechnical investigation often requires the use of drilling equipment to drill the surface of the rock and soil in advance, so a geotechnical directional drilling device is needed. Most of the existing geotechnical directional drilling devices are composed of a bracket and a drilling rig. The drilling rig can descend to drill the geology so that the rock and soil can be rolled out.

[0003] Existing application number CN202122685106.8 The utility model provides a geotechnical exploration drilling device, which relates to the field of geotechnical exploration. The geotechnical exploration drilling device includes a connecting seat and an auxiliary mechanism, and the auxiliary mechanism is arranged on a fixed pipe. The geotechnical exploration drilling device provided by the utility model drives the driving shaft to rotate by starting the motor, so that the connecting part drives the piston pad at the lower end of the pull rod to move back and forth inside the fixed vertical pipe, so that the water inside the water storage tank intermittently flows into the fixed vertical pipe and is sprayed out by the annular fixed nozzle, softening the soil layer, facilitating the drilling of the drill bit, and effectively avoiding dust, thereby ensuring a good drilling working environment; the foam float slides downward, driving the second induction block at its top to move down to counteract the first induction block. At this time, the battery energizes the warning light, so that the staff can be informed in time that water needs to be added.

[0004] Based on the above, the existing geotechnical directional drilling devices are mostly composed of a bracket and a drilling rig. The drilling rig can descend to drill the geology so that the rock and soil are rolled out, but geotechnical drilling usually requires geological exploration in multiple locations, so the geotechnical directional drilling device needs to be constantly carried by workers. In order to maintain stability during drilling, the bracket needs to be nailed into the ground when fixed, which is inconvenient to disassemble and assemble during transportation, time-consuming and labor-intensive. In the process of drilling with the drilling rig, it is easy to raise a lot of dust during the drilling process. Utility Model Content
