Abstract
A ventilation escape opening structure of a city utility tunnel belongs to the technical field of city utility tunnels. The underground comprehensive pipe gallery comprises an underground comprehensive pipe gallery body, an intermediate interlayer, a comprehensive vertical shaft, a ventilation pavilion and an escape well cover in sequence from bottom to top; utility tunnel includes electric power cabin and piping lane utility compartment, establishes the fire prevention division wall in the utility tunnel body, and fire prevention division wall middle part sets up prevents fire door to fire prevention division wall sets up the vent and flees the mouth as central symmetry, and the vent sets up ventilation blower and fire prevention valve, and it sets up perpendicular cat ladder to flee a 4, and middle intermediate layer is established and is ventilated and is fleed and combine the shaft. The advantage lies in, reduces to minimum the ground part, reduces the investment, reduces utility tunnel vent and the mouth of fleing and sets up alone, and weakening utility tunnel drill way is to the influence of city landscape geomorphology when can saving area.
Description
Technical Field
The utility model belongs to the technical field of city utility tunnel, in particular to city utility tunnel ventilation escape opening structure.
Background
The utility tunnel is an underground city pipeline utility tunnel. A tunnel space is built in the city underground, and various engineering pipelines such as electric power, communication, gas, heat supply, water supply and drainage and the like are integrated. The special escape opening and the special vent opening of the lifting opening are arranged, and unified planning, unified design, unified construction and management are implemented.
Utility tunnel belongs to underground tunnel structure, and inside still need guarantee pipeline maintainer's required space of daily maintenance and environment except satisfying the pipelaying. Power cable and heat supply pipeline heat dissipation can produce very big heat and humidity also great in the utility tunnel, and it seems especially necessary to set up piping lane ventilation system rationally. In addition, in the case of emergency, maintenance personnel need to evacuate to the ground from the nearby escape opening in the comprehensive pipe rack.
The ventilation pavilion is the terminal facility of utility tunnel ventilation system, with external direct intercommunication, the ventilation pavilion needs to be higher than ground, the pavilion side sets up ventilation shutter. The escape opening may be communicated with the outside at the same time, and a well cover is arranged and is level with the ground or slightly higher than the ground. In the utility tunnel project of construction in recent years, ground ventilation pavilion and the design problem of the well lid pattern of fleing and height show especially, can reduce the piping lane investment if combine the vent with the mouth of fleing to consider, reduce out ground drill way quantity simultaneously, more can weaken the influence of utility tunnel to the urban landscape geomorphology.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a city utility tunnel ventilation escape opening structure can satisfy utility tunnel ventilation needs under, can also satisfy the piping lane emergence accident back, the requirement of promptly fleing. Reduce out ground drill way quantity, weaken utility tunnel to the influence of city view physiognomy.
The utility model comprises an underground comprehensive pipe gallery body, a middle interlayer, a comprehensive shaft 31, a ventilation pavilion 3 and an escape well cover 2 from bottom to top in sequence; utility tunnel includes electric power cabin 6 and piping lane utility compartment 7, this internal fire prevention partition wall 61 that establishes of utility tunnel, fire prevention partition wall 61 middle part sets up prevents fire door, use fire prevention partition wall to set up vent 5 and escape opening 4 for central symmetry, vent 5 sets up ventilation blower 51 and fire prevention valve 52, escape opening 4 sets up perpendicular cat ladder 1, middle intermediate layer establishes ventilation and the comprehensive shaft 31 of fleing, comprehensive shaft 31 sets up perpendicular cat ladder 1, control box 9 can be placed to middle intermediate layer side wall, 31 top structure parts of comprehensive shaft exceed ground 0.3 meters, upper portion ventilation pavilion 3 is the steel, establish rain-proof tripe 32 all around, 3 top surfaces of ventilation pavilion and 2 fixed mounting of well lid of fleing.
The utility model discloses at this internal fire prevention division wall that sets up of utility tunnel with prevent fire door, both can realize that there is independent ventilation and escape way in every cabin fire prevention subregion, will merge two kinds of functions in the intermediate layer again and set up, will go out ground part and reduce to minimum, reduce the investment, reduce utility tunnel vent and flee for one's life mouthful and set up alone, weakening utility tunnel drill way to the influence of city view physiognomy when can save area.
The utility model combines the ventilation opening of the comprehensive pipe gallery and the escape opening, so that the maintenance personnel can not enter and exit from the escape opening under the normal working condition, and the ventilation system can also run normally; when an emergency occurs, the fan and the fire valve in the fire-proof subarea can be automatically closed, the ventilating shaft which can be safely escaped to the ground by maintenance personnel can be maintained, and the public shaft can be completely used for realizing two functions.
