Tunnl Lining Trolley

- Installation: First, the trolley is moved to the construction position along the track, and then the template is adjusted to the correct position and height through the hydraulic system.

- Concreting: After the reinforcement is placed, the concrete is poured into the template through a concrete pump truck. During the concreting process, the trolley bears the pressure of the concrete and maintains the shape and position of the template.

- Demoulding: After the concrete reaches the required strength, the template is removed by the hydraulic system, and then the trolley is moved to the next construction position.

Haide Tunnel Lining Trolley, is full - hydraulic automatic - walking lining trolley: It can realize automatic walking, positioning and form removal through the hydraulic system, which improves the construction efficiency and quality. It is widely used in the concrete secondary lining construction of highway and railway tunnels.

Composition

- Gantry frame: It is mainly composed of longitudinal beams, cross - beams, columns, etc., which bear the weight of the template and concrete.

- Formwork: It is designed according to the shape of the tunnel and is usually made of steel plates. It can ensure the dimensional accuracy and surface quality of the tunnel lining.

- Hydraulic system: It is used to control the lifting, translation and form removal of the template, which has the advantages of high precision and convenient operation.

- Walking mechanism: It is usually driven by an electric motor or a hydraulic motor, which can make the trolley move forward, backward, turn, etc.
