The tunnel inverted arch trestle is a specialized construction equipment used in tunnel engineering, designed to prevent interference between mucking haulage and inverted arch lining, while also serving emergency rescue functions.
The inverted arch trestle typically consists of main bridge, front and rear approach bridges, movable and fixed legs, inverted arch formwork, hydraulic supports, and hydraulic traveling mechanisms, as well as major systems such as automatic pouring system, automatic vibration system, and automatic control system.
The inverted arch trestle manufactured by Luoyang China Railway Strong Machinery Co., Ltd. features a box-type main girder structure with extremely high strength and rigidity, ensuring stable travel of heavy-duty vehicles with minimal deflection, while also providing emergency escape functions. The bridge deck adopts a full-coverage design, effectively enhancing overall machine safety. The trestle is equipped with a mobile working platform, greatly improving the efficiency of waterproof membrane installation and rebar binding operations. It is fitted with a mobile distribution cart that is easy, flexible, and efficient to operate, significantly reducing labor intensity. The trestle adopts circumferentially sliding formwork to achieve continuous pouring of the inverted arch, improving construction efficiency. Additionally, it is equipped with an anti-flotation system that effectively addresses the issue of inverted arch formwork floating, thereby enhancing the quality of inverted arch pouring.
The inverted arch trestle produced by China Railway Strong Machinery Company adopts an integrated mechanical-electrical-hydraulic design, with all operations completed via wireless remote control, offering easy operation, smooth performance, and reliable safety. It utilizes a hydraulic motor gear direct-drive configuration, which provides more stable and reliable trestle travel compared to chain drive. The trestle adopts rubber tire traveling mode, minimizing damage to the fill surface during movement.
China Railway Strong Machinery Company currently produces five major series of inverted arch trestle products, including double-track 36-meter, double-track 24-meter, single-track 36-meter, single-track 24-meter, and cantilever 12-meter models, with over 20 product variants, capable of meeting construction needs across high-speed railways, highways, and water conservancy and hydropower projects.
Using the China Railway Strong inverted arch trestle, compared to other similar products, can effectively reduce labor input by 30% and increase overall efficiency by over 20%. With 5 major series and 20 product variants, there is always one that suits you!
