The invention provides a combined type tunnel trolley guide rail which comprises steel buttresses and rails. The rails are fixed on the steel buttresses through fixing devices, the fixing devices are bolt bar pieces, the rails are provided with bolt holes matched with the bolt bar pieces, and the steel buttresses are provided with bolt holes matched with the bolt bar pieces. According to the technical scheme, compared with a traditional mode of mounting the rails by adopting pouring concrete continuous beams or concrete buttresses, engineering construction cost is reduced greatly, labor intensity of workers is relieved, and meanwhile the combined type tunnel trolley guide rail can be put into turnover utilization. The steel buttresses and the special rails are simple in machining and manufacturing process and convenient to use, and are manufactured in a machining plant, narrow tunnel construction site space is not occupied, and acceleration of construction progress is facilitated.
Description
technical field [0001] The invention relates to a track, in particular to a combined guide rail for tunnel trolleys. Background technique [0002] In the tunnel lining project, the steel formwork trolley is often used to erect the formwork for concrete pouring construction. Due to the two working conditions of the first pouring warehouse and the second pouring warehouse, the steel formwork trolley must be moved after the construction of the first pouring warehouse is completed. To the position of the post pouring bin. In order to facilitate the movement of the steel formwork trolley, guide rails are usually laid on the tunnel floor to erect the steel formwork trolley. The traditional construction method is to first pour two concrete continuous beams or multiple concrete buttresses on the tunnel ground, and then install the track on it as the walking guide rail of the steel formwork trolley. The main disadvantage of this construction method is: due to the need to pour concr...
