Tunnel Drilling Machine
Tunnel excavation blasting drilling function
Palm face blasting hole construction, which can drill cutting holes, peripheral holes, and bottom plate holes, suitable for various rock layers such as hard rock and medium soft rock;
Multi angle adjustment of drilling arm, precise control of hole position and depth, reducing tunnel over excavation and improving excavation quality;
High frequency impact rock drilling, with fast drilling speed, replaces traditional manual air drills and reduces labor intensity.
2、 Surrounding rock support drilling function
Anchor bolt hole/anchor cable hole drilling: Full directional drilling of arch crown, side wall, and inverted arch, used for reinforcing surrounding rock with system anchor bolts and prestressed anchor cables;
Locking foot anchor tube drilling: fixing the steel frame of the stepped tunnel to enhance initial support stability and prevent settlement and deformation of the surrounding rock;
Drainage hole construction: Install tunnel seepage drainage holes to divert surrounding rock groundwater and reduce seepage diseases.
3、 Advanced support and reinforcement function
Advanced small conduit drilling: Φ 42 small conduit grouting, suitable for pre reinforcement of shallow buried and fractured surrounding rock tunnels;
Large pipe shed and pipe drilling: equipped with casing follow-up technology, loose soil and pebble layers do not collapse holes, and large section openings prevent collapse;
Advanced grouting hole: filling grouting and consolidation grouting in the formation, reinforcing weak and fractured zones, and enhancing the self stabilization ability of surrounding rock.
4、 Advanced geological exploration and detection function
Horizontal drilling in front of the palm, exploring water, karst caves, faults, and gas fracture zones;
Long distance core drilling, real-time monitoring of rock changes, advance prediction of geological disasters, and avoidance of water inrush and collapse risks;
It can complete geological sampling and formation pressure detection, providing geological data for tunnel construction plans.
5、 Full section no dead corner operation function
The drilling arm can rotate 360 °, pitch up and down, swing left and right, and can be used for construction of high and low arches, low guide tunnels, and side inverted arches;
The telescopic propulsion beam is suitable for different tunnel section sizes, and single arm/multi arm models can synchronize porous construction to improve cycle efficiency;
The track model has a large climbing ability, and can operate stably on slopes, entrance slopes, and muddy tunnel bottoms.
6、 Multi power adaptive environmental protection operation function
Electric mode: zero exhaust and low noise inside the tunnel, meeting the requirements of explosion-proof and environmentally friendly construction in subways and urban tunnels;
Dual use of diesel/oil and electricity: operate independently when there is no external power source at the entrance, switch to electric mode for environmental protection when entering the entrance;
Sealed dust-proof drilling structure reduces dust inside the tunnel and improves the construction environment.
7、 Intelligent and precise construction function
Automatic depth counting, precise control of drilling depth, avoiding uneven depth;
Anti jamming drill automatic retreat protection, automatic pressure relief when encountering interlayers or caves, protecting the drill rod power head;
High end models support automatic drilling for drawing import, remote control, construction data storage, and unmanned operation in high-risk areas.
