The tunnel invert arch trestle is a specialized construction equipment designed for tunneling operations. It is used to prevent interference between muck removal traffic and the invert arch lining, while also serving as a dedicated tool for emergency rescue and disaster relief.

Product Introduction

　　The tunnel invert arch trestle is a specialized construction equipment designed for tunneling operations. It is used to prevent interference between muck removal traffic and the invert arch lining, while also serving as a dedicated tool for emergency rescue and disaster relief.

　　The inverted arch trestle typically consists of several key components, including the main bridge, front and rear approach bridges, movable and fixed support legs, inverted arch formwork, hydraulic supports, and hydraulic walking mechanisms, as well as major systems such as an automatic pouring system, an automatic vibration system, and an automatic control system.

　　The arch support trestle bridge produced by Luoyang China Railway Qiangli Machinery Co., Ltd features a box-type structure for its main beam, which boasts extremely high strength and rigidity. This design ensures stable operation and minimal deflection even under heavy loads, while also incorporating emergency evacuation and escape functions. The bridge deck adopts a fully enclosed design, significantly enhancing the overall safety of the equipment. The trestle bridge is equipped with a mobile working platform, greatly improving the efficiency of waterproof membrane laying and rebar tying operations. A mobile concrete spreading cart has been installed, offering simple, flexible, and highly efficient operation, thereby substantially reducing workers' physical labor intensity. The trestle bridge utilizes a circumferential sliding formwork system, enabling continuous pouring of the arch support and boosting construction efficiency. Additionally, it is fitted with an anti-floating system that effectively addresses the issue of formwork floating during arch support pouring, thereby enhancing the quality of the arch support casting.

　　The arch support trestle bridge produced by China Railway Qiangli adopts an electromechanical-hydraulic integrated design. All operations are performed via wireless remote control, making it easy to operate, smooth in performance, and safe and reliable. It uses a hydraulic motor-gear direct-drive system; compared to chain drive, this trestle bridge moves more smoothly and reliably. The trestle bridge employs a rubber-tire walking mode, which minimizes damage to the filling surface during its movement.

　　China Railway Qiangli currently produces five major series of arch support trestles—over 20 models in total—including double-track 36-meter, double-track 24-meter, single-track 36-meter, single-track 24-meter, and cantilever 12-meter types—capable of meeting the construction needs of all scenarios, such as high-speed railways, expressways, and water conservancy and hydropower projects.

　　By using the China Railway Qiangli arch support trestle, compared to other similar products, it can effectively reduce labor input by 30% and increase overall efficiency by more than 20%. With five major series and 20 varieties, there's bound to be one that's right for you!
