Heavy-Gauge Profile Forming

Tunnel support profiles commonly rely on a deep or curved cross-section to provide greater structural stiffness. The forming process gradually converts a heavy steel strip into the required section while controlling deformation across the entire width.

The roller arrangement is selected according to the steel grade, thickness, profile depth, and bending radius. Reinforcing ribs, return edges, mounting flanges, or connection surfaces can be incorporated into the section when required by the support design.

For curved tunnel supports, the completed profile may undergo a separate bending operation after roll forming so that the straight section can be matched to the tunnel radius.

Technical Parameters

Structural Section & Tunnel Assembly

A tunnel support profile is normally installed as part of a larger support framework rather than used independently. The finished members can be connected to neighboring frames, longitudinal members, bolts, plates, or other reinforcement components according to the underground support design.

The machine can produce straight sections first, while a downstream bending unit can form them into the required tunnel curvature. This combination is useful when the support profile must follow a specific arch radius.

For profiles requiring connection holes, the punching operation can be incorporated into the production line. Hole spacing and location can be established according to the connection layout between adjacent support members.

Equipment Configuration

Underground Construction Applications

The finished profiles are used in underground structures where steel support members are required to maintain the stability of excavated spaces.

Typical applications include:

Railway tunnel support

Road tunnel construction

Mining roadway support

Underground passages

Utility tunnels

Water-conveyance tunnels

Underground service corridors

Temporary excavation support

In mining applications, the profile may be installed as part of a steel arch support system. In civil tunnel construction, formed steel sections can be combined with shotcrete, rock bolts, mesh, or other reinforcement methods depending on the engineering design.

Profile dimensions can vary significantly between projects. A shallow section may be sufficient for one application, while deeper or thicker profiles may be required where greater structural capacity is specified.

Profile Design & Heavy-Duty Manufacturing

The forming tooling is designed from the finished tunnel support cross-section. Material thickness and steel strength are then used to determine the required forming force, shaft diameter, transmission capacity, and machine-frame strength.

Key design information includes:

For heavy tunnel sections, the machine can use reinforced roller stands and larger-diameter shafts to reduce deflection under forming load. The transmission system can likewise be selected according to the actual material specification rather than applying the same drive configuration used for light-gauge profiles.

Where the support profile must follow an arch-shaped tunnel, a hydraulic bending system can be added after roll forming. The forming and bending stages can then be treated as two coordinated processes: the roll forming section establishes the structural cross-section, while the bending equipment establishes the required installation radius.
