Hydraulic Railway Formwork Tunnel Lining Trolley

Hydraulic Railway Formwork Tunnel Lining Trolley

The steel mold is the working device of the trolley. Its appearance quality and dimensional accuracy directly determine the quality of the concrete lining. At the same time, it is the most difficult part to process. A reasonable processing and welding process has been formulated, and a special assembled welding tire mold has been designed and processed. In order to ensure the accuracy of the overall dimensions, minimize welding distortion, and ensure that the outer surface is smooth and free of defects such as unevenness. In order to control the misalignment of adjacent formwork, the stabilizing pin of interference fit is used to fix the connecting plate of adjacent formwork as a whole, which effectively controls the misalignment of adjacent formwork caused by the gap between bolt holes and ensures the quality of concrete lining.

The Railway Tunnel Trolley adopts hydraulic transmission, which simplifies the structure of the trolley frame and reduces the weight. At the same time, it also improves the flexibility and diversity of the structure. After the analysis and comparison of various trolley frame structure schemes, the strength calculation and optimization select 9m four-door frame 12m The main door frame structure scheme reduces the structural weight by more than 40% compared with the mechanical type, and reduces the production cost by more than 25%.

product feature:

* It is widely be used in all kinds of tunnel concrete construction
