Central axis pre grooving machine
The YQC7000 central axis pre grooving machine is one of the core equipment for pre grooving method tunnel construction. It has functions such as groov
Product details
Product Features
1. Good control of settlement
Due to the simultaneous completion of pre cut groove excavation and concrete pouring, stress release causing soil strain is avoided.
2. Continuous arch shell, highly stable
Due to the prefabrication of continuous arch shells along the transverse direction of the tunnel, there are overlaps between arches along the longitudinal direction of the tunnel, forming a continuous spatial arch structure with high mechanical stability;
Due to the use of mechanized cutting construction, damage to the surrounding rock can be reduced.
3. Economic convenience
As an independent tunnel excavation construction technology, avoid secondary lining such as shotcrete and steel arch support operations.
