Abstract
The invention relates to a two-leaf protective door or a two-leaf cavity door of a tunnel. The two-leaf protective door or the two-leaf cavity door comprises a door frame and two door leaves connected with the door frame through hinges. Each door leaf is of a hollow cuboid structure and is internally provided with an up-down connection rod type lockout structure and a steel framework used for supporting the hollow cuboid structure. The door frame, the hinges and the cuboid structures of the door leaves are all prepared by glass fiber reinforced plastic. By adopting the door leaves and the door frame which are made of the glass fiber reinforced plastic materials, the whole two-leaf protective door or the two-leaf cavity door of the tunnel has the advantages of being light and high in strength and is resistant to corrosion and fatigue, good in durability, convenient to maintain and replace, suitable for the complex environment inside the tunnel and capable of greatly prolonging the service life of tunnel equipment. Furthermore, by improving the external structure of the door frame and the structure of the hinges, the connection firmness of the door leaves and the door frame is further enhanced, thus, the firmness degree of a whole body is improved, and the fatigue resistance of the two-leaf cavity door can be greatly improved.
Description
Technical field
The invention belongs to railway construction technical field is and in particular to a kind of structure of the door of all kinds of cavern in tunnel.
Background technology
Tunnel is the building channel of automobile or train passage.It is usually provided with the cavern of place apparatus, tunnel is prevented in tunnel
Shield door (Dong Shimen) is then to apply in railway tunnel, such as transverse passage-way, various kinds of equipment (ventilation, communication, electric power etc.) cavern, promptly rescue
Help in the caverns such as war, emergency exit, refuge, vertical shaft incoming tunnel, inclined shaft incoming tunnel, repeater, transformer station, its effect has
Fire prevention, antiknock, resist the wind-induced positive and negative blast of train periodicity piston, prevent device damage and support personnel safety and arrange
Specific use door.
Door of the prior art is mainly prepared from using armored concrete or steel, but they all have certain lacking
Fall into, armored concrete door weight is big, switch gate is inconvenient, assemble difficult, yielding, long preparation period；Steel door is perishable, many
Number fire resistance is not enough.And both doors all have the shortcomings that poor durability, fatigue resistance are poor, need time-based maintenance and safeguard.
Content of the invention
Protective door for tunnel of the prior art cavern or the defect of cavern's door presence, the present invention provides a kind of intensity
High, corrosion-resistant, endurance, good endurance, antiknock load are not less than 0.1mpa, fire endurance is not less than the biparting tunnel of 3 hours
Protective door or Dong Shimen.
