Tunnel Backfill Repair Method Using Urethane Injection "Tn-p Method"

Tunnel Backfill Repair Method Using Urethane Injection "Tn-p Method"

Polyurethane injection method for tunnel backfill repair with excellent workability.

The "Tn-p Method" is a tunnel repair method designated as a "Technology for Promotion of Utilization" by NETIST. The injection machine's pump sends both Liquid I and Liquid R to the mixing head, where they are mixed through air agitation to form foamed polyurethane (Achilles Airon-R). The injection equipment is very compact, and the filling material is transported in liquid form (in drums) at about 1/40 to 1/12 of the volume after foaming, allowing all materials and equipment to be loaded onto a single 4-ton truck. 【Features】 ■ Excellent workability ■ Compact injection equipment ■ All materials and equipment can be loaded onto a single 4-ton truck ■ Effective for stopping groundwater *For more details, please refer to the PDF document or feel free to contact us.

Achilles Tn-p Method for Tunnel Backfill Repair Using Urethane Injection

Achilles Tn-p Method for Tunnel Backfill Repair Using Urethane Injection

Cost reduction with 40 times high foaming urethane! Improved workability with compact injection equipment!

The "Achilles Tn-p Method," which is a "NETIS Utilization Promotion Technology (formerly registered)," is a tunnel repair technology that involves injecting polyurethane foam into the void behind the tunnel lining for repairs. It is effective in preventing sudden collapse accidents of the ground behind the tunnel lining. With 40 times the expansion of conventional polyurethane, it is economical, and the injection equipment is compact, improving workability. Its lightweight nature reduces the load on the tunnel, and it solidifies in just a few minutes, thereby reducing the risk of accidents caused by material leakage from cracks. 【Features】 ■ The injection equipment is compact, and the injection material is packaged in drums, allowing everything to be loaded onto a single 4-ton truck. ■ Ultra-lightweight, reducing the load on the tunnel lining. ■ Rapid solidification reduces the risk of accidents due to material leakage. ■ Environmentally friendly with no use of fluorocarbons in the foaming agent. Achilles also offers "civil engineering methods" beyond tunnel repair technology, including "lightweight embankment methods." → "Polyurethane LH Method," which sprays on-site polyurethane foam. → "EPS Method," which stacks expanded polystyrene blocks. As the only manufacturer capable of providing these two lightweight embankment methods, we can propose the most suitable construction methods. *For more details, please refer to the catalog. "Construction examples" are also available! Don't miss this opportunity!

Tunnel Backfill Repair Method Using Urethane Injection "Tn-p Method"

Tunnel Backfill Repair Method Using Urethane Injection "Tn-p Method"

Cost reduction with 40 times high foaming polyurethane! Improved workability with compact injection equipment!

The "Tn-p Method," which is a "NETIS Utilization Promotion Technology (Old Registration)," is a tunnel repair technique that involves injecting polyurethane foam into the void behind the tunnel lining for repairs. It is effective in preventing sudden collapse accidents of the ground behind the tunnel lining. With 40 times the expansion of conventional polyurethane, it is economical, and the injection equipment is compact and easy to work with. Additionally, it is lightweight, which reduces the load on the tunnel, and it solidifies in just a few minutes, thereby reducing the risk of accidents caused by material leakage from cracks. 【Features】 - The injection equipment is compact, and the injection material comes in drum cans, allowing everything to be loaded onto a single 4-ton truck. - Ultra-lightweight, reducing the load on the tunnel lining. - Rapid solidification reduces the risk of accidents due to material leakage. - Environmentally friendly, using no fluorocarbons in the foaming agent. ★ To promote the widespread adoption of this method, we have established the "Polyurethane Void Injection Association."
