Abstract
The invention discloses an entire-underground cable tunnel safety manhole being used also as a ventilation shaft, which pertains to the technical field of power supply and distribution circuits and comprises an underground firewall with a door, an aboveground firewall, a fire door, a propeller fan, a fire damper, a safety manhole, a vertical ladder, a stair hall, a sump pit and a dredge pump; wherein the safety manhole is also used as a ventilation shaft and adopts an entire-underground type. The entire-underground cable tunnel safety manhole has the advantages that: as the internal structure of the ventilation shaft is optimized, the requirements of ventilation, drainage, fire prevention and routing inspection of the cable tunnel are satisfied, and the entire structure of the ventilation shaft is arranged underground, thus solving the problem of the overall beautiful appearance of a factory and effectively reducing the construction cost. The channel and the ventilation opening of the ventilation shaft are integrated into one, thus being capable of being flexibly arranged without affecting the arrangement of other facilities on the ground in the factory district.
Description
Technical field
The invention belongs to the power and distribution supply cable technical field, safety manhole ventilating shaft of holding concurrently in a kind of full underground type cable tunnel particularly is provided, be applicable to the ventilating shaft and the safety manhole design of trunk electric power pipe network cable tunnel in the factory.
Background technology
Traditional cable tunnel ventilating shaft is positioned on the ground, and floor space is big, arranges intensively, and architectural appearance is difficult for beautifying, and influences the attractive in appearance of plant area's integrated environment, has more drawback.When especially being positioned at both sides, factory owner arterial highway, be difficult for addressing and planning route more, often conflict, be difficult for coordinating with plant area's building and other pipelines.
Traditional cable tunnel ventilating shaft is to utilize the tunnel internal top board as buffer platform, need could arrive ground by the twice catladder when attendant patrols and examines, for patrolling and examining and safe escape causes very big difficulty.
Summary of the invention
The object of the present invention is to provide a kind of full underground type cable tunnel safety manhole ventilating shaft of holding concurrently, solve tunnel ventilation, fire prevention, draining, patrolled and examined the requirement of maintenance, have the characteristics that occupation of land is little, architectural appearance is beautified, optimized plant area's integrated environment simultaneously, move towards to plan science, reasonable, economic more in total figure layout and each pipeline.
Of the present invention comprising: down-hole band door fire wall, aboveground fire wall, labeled door, propeller fan, fire resisting damper, safety manhole, catladder, staircase, sump, dredge pump; The double ventilating shaft of doing of safety manhole adopts complete underground mode, the above no facility in ground, and it is attractive in appearance not influence outdoor environment; Leading to outdoor staircase can be provided with flexibly, does not influence the layout of ground installation; Solve tunnel ventilation, fire prevention, draining and attendant and patrol and examine problem.
Fire prevention and attendant that down-hole band door fire wall, aboveground fire wall, labeled door are used to solve the tunnel patrol and examine problem, down-hole band door fire wall is partitioned into several independently fire compartmentations with the tunnel, fire wall is provided with cable sleeve, cable can pass fire wall by sleeve pipe, the tight shutoff of fire prevention calking can be adopted in slit between sleeve pipe and the cable, can prevent effectively that like this flame from spreading along the tunnel to other position, the tunnel personnel of patrolling and examining can enter adjacent fire compartmentation by labeled door on the wall.Aboveground fire wall will be divided into two subregions in the ventilating shaft, avoided flame to scurry along manhole and fired to adjacent sectors.
Propeller fan, fire resisting damper are used to solve the ventilating problem in tunnel, every 30～100 meters needs one place's ventilating shaft is set along the tunnel direction, ventilating shaft adopts the mode of downcast-air draft well-downcast to be arranged alternately, propeller fan is selected air intake or air draft for use according to the function of ventilating shaft, corresponding each blower fan all is provided with 1 fire resisting damper, when meeting the condition of a fire, ventilation fan and fire resisting damper are closed automatically by electrical interlocks.After finishing, the condition of a fire can discharge fume by manually opened blower fan.
Sump, dredge pump are used to solve the drainage problem in tunnel, each ventilating shaft is provided with two place's sumps, one place is arranged in the tunnel, is used for tunnel drainage, and a place is arranged in the staircase, be used for row's rainwater when the rainy day, dredge pump is fixedly mounted in the sump, generally adopts the chain automatic control of liquid level, and high liquid level opens pump, low liquid level termination of pumping also can manually be controlled by the personnel of patrolling and examining.Gutter is connected in the drainage pipeline networks of plant area.
Safety manhole, catladder, staircase are used to solve attendant's the problem of patrolling and examining, and the attendant can be by manhole and catladder by going up to aboveground in the tunnel, down-hole, go to outdoorly again by staircase, and staircase can be according to the outdoor facility flexible arrangement.
Advantage of the present invention
By optimization to the ventilating shaft internal construction, the requirement of promptly reached cable tunnel ventilation, draining, preventing fires and patrolling and examining, again with undergroundization of entire infrastructure of ventilating shaft, because the spacing of ventilating shaft must guarantee within 100 meters, and generally all be arranged in plant area turnpike road both sides, and very big for the influence attractive in appearance of plant area, adopt this kind design can effectively solve aesthetic problem, owing to cancelled earth construction, effectively reduced construction cost; Under the situation that guarantees original function, adopt complete underground design, reduced the ground occupation of land.
The passage and the ventilation opening of ventilating shaft unite two into one, and can be provided with flexibly, do not influence the layout of plant area's other facility of ground.
By adopting the staircase form to ground in the ventilating shaft, help patrolling and examining and safe escape.
Description of drawings
Fig. 1 is ventilating shaft-3.000 plan view.
Fig. 2 is ventilating shaft-6.400 plan view.
Fig. 3 is the ventilating shaft sectional drawing.
The specific embodiment
Fig. 1 and Fig. 2 are a kind of specific embodiment of the present invention.
Ventilating shaft as shown in Figure 1-3.000 meter plan view, the personnel of patrolling and examining can be by staircase by outdoor down to-3.000 planes, enter the tunnel by manhole again.Be provided with the twice labeled door in the staircase, can enter different fire compartmentations, the other propeller fan that is provided with of labeled door, air-flow can enter in the cable tunnel by blower fan and manhole, because the down-hole has fire wall to separate, so the ventilation of each fire compartmentation all is relatively independent, do not disturb mutually.The staircase end is provided with place's sump, owing to do not have building to block more than the staircase ground, the rainy day has rainwater and flows in the staircase, flows into unified draining in the sump.
