Steel Tunnel Formwork System Stable Structure For Mining Method Tunnel Lining

Hydraulic tunnel steel formwork underground working machine for Mining method tunnel lining

1. Tunnel lingling trolly:

The trolley developed by Boyoun which is concentrated on commonality, humanity construction. Structure reliable, convenient operation, good tunnel surface etc. The trolley widely used in highway, railway, water projects, hydraulic engineering, public projects, and defense industry projects. The tunnel trolley which consist of formwork assembly, traveling device, portal-frame assembly, Principal and master-slave traveling device, lateral hydraulic oil cylinder, lateral support jack and portal-frame support jack etc.

There are 6m, 7.5m, 9m, 10.5m, 12m different specifications. Customers can choose it according to tunnel length and construction period. The lining trolley can be divided into side & roof arch type, fully round acerate-beam type, the bottom platform needle-beam type, fully round through type etc.

2. Design principles:

- light weight;

- simple, strong and stable structure;

- moved, mounted and stripped easily;

- strong reusability; - small deformation under force;

- adequate space under traveler and providing a big space for bars and formwork construction operation.
