At present, in the domestic tunnel construction process, blasting charging, steel arch installation, anchor construction and reinforcing steel mesh laying is mainly used manually with the help of simple platform construction, the number of people working, labour intensity, installation difficulty, low construction efficiency and high safety risk.
Uniroc Vertical Arch Charging Trolley combines blasting charging, arch installation, anchor construction, reinforcing mesh laying and other overhead work functions into one, which can be applied to blasting charging, multi-bay arch prefabrication and segmentation, multi-bay arch prefabrication and folding, single-bay arch folding, locking anchor, system anchor, and overrunning small conduit in highway, railway, and water conservancy and hydroelectricity full cross-section method, step method, and other construction operations.
Demolition charges
The equipment is equipped with oversized working platform and hole clearing device, which can accommodate 6-8 people working at the same time. The operator operates the platform of the vertical arch charging trolley to move flexibly by himself, and completes the blasthole clearing operation quickly by using the air compressor and clearing pipeline that comes with the equipment.
Multi-bay precast arch installation
Arch installation is an important part to ensure the stability and safety of the surrounding rock, prefabricated platform assembly and connecting bar mesh welding can be completed in the factory. Say goodbye to the traditional shoulder-carrying and hand-carrying, and it can be adapted to a variety of working conditions such as full-section and step method.
Anchor construction
Construction Advantages
Platform lifter HLG312M/HLG312E/HLC312E
Multi-purpose machine for charging, vertical arching and anchoring
It is equipped with two types of chassis: car chassis and engineering chassis, which can meet the requirements of different construction conditions. The equipment is integrated with multi-function, one equipment can complete the prefabricated arch installation, blasting charging, anchor construction and other processes.
Saving money
Significantly reduce construction costs, only 4 people can complete the charging, arching, anchoring multi-process operations, a device can take into account multiple palm face, saving manpower investment of 8-10 people, annual savings of about 1 million in labour costs, about 1 year to recover the investment costs; at the same time, charging, arching team can be merged into a single team to reduce the difficulty of management;
Safety
Improve construction safety, construction personnel working time in the cave is greatly reduced, reducing the safety risk of operators;
Efficient
The construction efficiency is greatly improved, 4 operators can complete the full section loading in 1h, and the three-bay arch installation can be completed in 45 minutes;
Multi-functional
Work rotation time is greatly reduced, and the construction of locking foot anchors, system anchors and overrunning small conduits can be completed at the same time.
By adopting Uniroc platform lifter, together with face drill rig and shotcrete machine, it can quickly complete the drilling, charging and arch installation, anchoring and slurry spraying operations at the palm face, completely abolish the simple platform operation and the air compressor station outside the cave, and achieve the full mechanisation of the tunnel construction operation.
At present, Uniroc platform lifters have been applied in a large number of key projects such as Highland Railway, Yukun High-speed Railway, West-10 High-speed Railway, Xixiang High-speed Railway and Zhenguang High-speed Railway, which have been fully recognised by the construction units. Uniroct, so that the tunnel construction is safer, more economical and more efficient!
