Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of geotechnical construction equipment, in particular to a TBM mounted full-angle normal deep anchor hole drilling machine. BACKGROUND

[0002] With the continuous progress of domestic technology, China has become the world's largest shield / TBM producer, with a production of 661 units in 2023. These equipment has been widely used in the fields of railway, highway, comprehensive pipe gallery, underground space development, water conservancy and hydropower (including water diversion project, pumped storage power station construction), mine and other fields. However, under extremely complex geological conditions, such as fracture zone, fault and extrusion deformation, TBM construction often encounters difficulties, resulting in slow construction progress, even the phenomenon of machine jamming, which seriously affects the construction progress and safety, and greatly increases the additional construction cost. In view of the above problems, full-circle normal long and strong anchoring scheme needs to be carried out behind the TBM cutterhead in construction.

[0003] The anchor rod reinforcement and support technology has been widely used in the fields of tunnel, slope and underground engineering, which is a support method that anchors the anchor rod in the rock mass through drilling, anchors the anchor rod and surrounding rock into a whole through grouting, and enhances the stability of surrounding rock by using the tensile shear effect of anchor rod, which has the advantages of high support strength, wide application range, flexible construction and other advantages. The anchor rod reinforcement effect is closely related to the drilling depth, whether the drilling is along the normal angle and the drilling efficiency. The traditional anchor rod construction usually adopts independent anchor rod drilling machine or TBM mounted anchor rod drilling machine. However, the independent anchor rod drilling machine is operated by manual operation, which has high labor intensity, and in addition, there will be space interference with TBM construction during operation, which leads to low efficiency of anchor rod construction and affects the support time efficiency. The conventional TBM mounted drilling machine cannot carry out normal drilling operation in local narrow space, because the drilling direction and normal angle are about 23°-43°, which will cause two problems, one is that the normal deviation must be controlled within 15°, which will increase the safety risk of anchor cable construction or even cannot be constructed, the other is that if the anchor rod cannot be constructed normally, not only the anchoring efficiency of anchor rod will be reduced, but also the non-normal drilling depth will be longer to ensure the effective drilling depth, which will increase the construction cost. At the same time, the drilling depth of TBM mounted drilling machine is shallow, generally about 3m, and for small diameter TBM, the drilling depth will be smaller. In the reinforcement of surrounding rock under complex geological conditions, the anchor hole construction depth often needs to reach 6-8m or even more than 12m.

[0004] At present, the TBM-mounted drill in the prior art cannot achieve the above drilling depth target. In addition, most of the drills are subject to insufficient flexibility of the positioning mechanism, especially in the narrow space of the TBM, it is difficult to achieve rapid positioning, the positioning time is long, and the existing drill has low drilling and rod connecting efficiency, which seriously affects the anchoring construction quality and supporting time efficiency. Therefore, the TBM-mounted drill capable of efficiently performing 360° full-angle, normal and deep anchor hole drilling operations in the narrow space of the TBM will be an effective measure to effectively ensure the TBM to smoothly pass through the broken zone, fault and extrusion deformation and other extremely complex geological conditions.
