Abstract
During the operation of the tunnel crossing, to maintain its required technical condition, preventive and repair work is carried out, with the exception of track work, by forces and means of the track distance.
When servicing tunnel crossings, compliance with safety regulations for people, as well as the established mode of train traffi c, must be ensured. To ensure the necessary conditions for the operation and repair of technological equipment, technological service platforms, mezzanines, stairs with non-removable railings are arranged at intersections. When using non-removable or bulky guards during maintenance and repair work at tunnel crossings on highways, the safe movement of vehicles and people is quite problematic.
In cramped tunnel conditions, instead of fences having a welded structure, it is proposed to use a removable railing structure that will not interfere with the movement of railway transport and ensure the safety of work processes. The removable railing device includes: a fastening plate, a fastening bracket into which the railing plate is installed.
The main parameters of removable railings are determined. The sequence of installation of a replaceable fence is described.
The use of removable railings in the enclosing structures will ensure the passage of vehicles, taking into account the requirements for the safety of working processes at tunnel crossings without disturbing the train traffic.
