Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction drilling, in particular to a tunnel construction drilling mechanism. Background Art

[0002] During tunnel construction, since a certain volume of closed fissure water may be stored in the bedrock cracks, the closed fissure water may suddenly gush out due to factors such as construction excavation and blasting, causing harm to the construction. Therefore, during tunnel construction, geological advance forecasting and advance drilling should be strengthened to prevent harm caused by sudden water gush, and tunnel construction drilling equipment will be used.

[0003] During the drilling process, once a traditional drilling mechanism encounters water gushing, it is usually necessary to stop drilling and take out the drilling mechanism for drainage, which not only affects the drilling efficiency, but also increases the project cost. Although there are some drilling mechanisms with drainage functions on the market, most of these mechanisms need to completely take out the drilling mechanism for drainage every time they encounter water gushing, which is cumbersome and inefficient to operate. In addition, during the drainage process, these mechanisms are usually unable to monitor the drilling depth in real time, which brings inconvenience to the construction. Therefore, in response to the above technical problems, a tunnel construction drilling mechanism is proposed herein. Utility Model Content
