Background
Since twenty-first century, along with the high-speed development of railway construction in China, high-standard double-track railways with the speed of 200km per hour are increasingly constructed, particularly in mountainous areas in the middle and western regions, line extension is limited by various factors such as large curve radius, complex terrain and geological conditions and the like, the scale of the tunnel is rapidly increased, the number of long and large mountain tunnels is increased, and meanwhile, the requirements of the long tunnel on auxiliary tunnels are increased by considering factors such as construction period, operational maintenance, disaster prevention, evacuation and rescue and the like.
In a conventional disaster prevention evacuation rescue project, particularly a repair-combined emergency rescue station in a tunnel, the evacuation requirement of people after a train on fire stops is met, and an independent people evacuation channel and a smoke evacuation channel are required to be arranged according to the principle of separating people from smoke, as shown in fig. 1 and 2. The personnel evacuation channel is connected with the evacuation flat guide and used for evacuating personnel outside the tunnel, and the smoke exhaust channel is connected with the smoke exhaust channel and used for exhausting fire smoke generated by the fire train, namely at least two auxiliary tunnels connected outside the tunnel need to be arranged on the tunnel body rescue station section. Due to the restrictions of terrain and geological conditions and environmental protection, the selection conditions and difficulties of the auxiliary tunnel with proper length and good entrance conditions are difficult to find on the key lines affecting the construction period of a newly built project, especially in the complicated and hard mountainous areas, so that the arrangement of the auxiliary tunnel at the rescue station is very necessary to be simplified.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a control and separate supplementary gallery structure in tunnel is provided to improve the single supplementary gallery and operate the period rate of utilization, reduce the supplementary gallery quantity in rescue station section, thereby solve the problem of the supplementary gallery site selection difficulty in complicated and hard mountain area, reduce the engineering scale simultaneously, reduce engineering cost.
The utility model provides a technical scheme that its technical problem adopted as follows:
the utility model discloses a control supplementary gallery structure of partition tunnel, the lining cutting structure of supplementary gallery in tunnel comprises hunch wall preliminary bracing structure, hunch wall mould building lining cutting structure and bottom plate structure, characterized by: a reinforced concrete vertical partition wall for dividing the section of the tunnel auxiliary gallery into a personnel evacuation channel and a smoke exhaust channel is arranged in the tunnel auxiliary gallery, the upper end of the reinforced concrete vertical partition wall is fixedly connected with the vault part of the arch wall molded lining structure, and the lower end of the reinforced concrete vertical partition wall is fixedly connected with the bottom plate structure; and a buried rubber waterstop is buried in the longitudinal construction joint of the reinforced concrete vertical partition wall.
The utility model has the advantages that the auxiliary tunnel structure with the left and right separation tunnels replaces the traditional auxiliary tunnel structure, on one hand, the principle of separating human smoke in disaster prevention evacuation rescue is satisfied, the evacuation of people and the smoke pumping and discharging are both in independent space, and the utilization rate of a single auxiliary tunnel during operation is improved; on the other hand, additional auxiliary tunnels are avoided, and the problem that the auxiliary tunnels are difficult to select addresses is effectively solved. Meanwhile, the scale of the auxiliary tunnel project is reduced, and the construction cost is reduced.
