The full-circle needle-beam lining trolley is a specialized mechanized equipment for full-circle cross-section concrete lining in underground engineering. Its core positioning is to "replace traditional full scaffolding + combined steel formwork," addressing customers' core pain points of low construction efficiency, high safety risks, poor lining quality, and high labor costs.
In response to the pain points of the water conservancy industry, our company has taken the lead in launching the full-circle needle-beam lining trolley. It is primarily suitable for full-circle cross-section lining construction in various underground engineering projects.
I. Applicable Scenarios:
1. Water conservancy and hydropower engineering: diversion tunnels, water conveyance tunnels, pressure pipelines, surge shafts.
2. Transportation engineering: highway/railway circular tunnels, municipal utility tunnels.
3. Other engineering: mining roadways, underground utility tunnels, etc. Applicable tunnel diameter: φ2m ~ φ18m. Lining thickness: 0.3m ~ 2.0m.
II. Functional Advantages
① Highly efficient and labor-saving: Replaces traditional full scaffolding, reducing labor by over 50%. Formwork erection and stripping are completed with one touch, improving single-cycle operation efficiency by 30%+.
② Superior quality: Full-circle one-time forming, no construction joints, high lining precision, good impermeability, reducing rework costs.
③ Strong adaptability: Customizable for tunnel diameters of 2m~18m, suitable for both thick and thin linings, universally applicable across water conservancy, transportation, and other industries.
④ Safe and reliable: Automated operation, reduced high-altitude work, multiple safety protections, lowering the risk of safety accidents.
⑤ High cost-effectiveness: Formwork can be reused over 500 times, reducing construction costs over long-term use.
