Abstract
The utility model be related to cable tunnel escape technical field, specifically it is a kind of suitable for cable bilateral arrange cable tunnel escape between, including tunnel body, escape between, run stair, cable, between described escape include superstructure and underground structure；Described many race stair include off stair and at least one upper strata stair, it is characterised in that：Set on the side wall of tunnel body between the tongue formation escape of outwardly convex, many race stair risen toward ground are provided with described escape.The utility model compared with prior art, realizes while the requirement of electrical cable bilateral arrangement is met and is not required to realize the arrangement between escape by overall increase tunnel width, so that with more preferable economy.
Description
Technical field
The utility model is related to cable tunnel escape technical field, specifically a kind of to be applied to what cable bilateral was arranged
Between cable tunnel escape.
Background technology
Cable tunnel is widely used as a kind of structure of provided underground cable by China, and it is arranged uses cable more
Bilateral arranges that centre is the mode of access path.However, the length of cable tunnel is generally longer, need to preferably it be examined in design
Consider escape and evacuation is required.According to China specification GB50229-2006《Thermal power plant and Substation Design fire safety rules》, electricity
Cable tunnel two ends all should set the extra exit towards ground, and when its length is more than 100m, the spacing of extra exit should not surpass
Cross 75m.Generally, it is vertically terraced using metal more than the extra exit of cable tunnel.However, according to China specification GB50016-2014
《Code for fire protection design of buildings》, construction area is not more than 500m2, number of users is no more than 30 people and buried depth is not more than 10m ground
Lower building, when needing to set 2 extra exits, one of extra exit can be vertically terraced using outdoor metal is led directly to, and
Another extra exit is then needed using between escape.Therefore, in order to preferably suit the requirement in specification to escape and evacuation, cable tunnel
At least 1 is needed to lead directly to outlet between outdoor escape in the extra exit in road.Cable is equipped with when the both sides of cable tunnel and
Tunnel width is narrower, when buried depth is deeper, and setting between escape often turns into the difficult point of design.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, is formed by way of the unilateral wall in tunnel is locally extended out
Between cable tunnel escape, to adapt to the narrow cable tunnel for needing bilateral to arrange cable.
Above-mentioned purpose is realized, a kind of cable tunnel arranged suitable for cable bilateral, including tunnel body, escape is designed
Between, run stair, cable, between described escape include superstructure and underground structure；Described many race stair include off building
Ladder and at least one upper strata stair, it is characterised in that：The tongue formation escape of outwardly convex is set on the side wall of tunnel body
Between, provided with many race stair risen toward ground in described escape.
The off stair of described many race stair are arranged in escape at tunnel body opposite side.
The cable of side is uninterruptedly arranged along the wall between escape between the escape.
The vertical plane of the tongue of described outwardly convex is trapezoidal or square or arc line shaped.
Underground structure between described escape uses reinforced concrete structure, and the superstructure between escape uses masonry structure
Or light section steel structure.
Superstructure between described escape is provided with door and window.
Sensing lamp is set in described escape.
The utility model compared with prior art, is realized while the requirement of electrical cable bilateral arrangement is met and is not required to
Arrangement between escape is realized by overall increase tunnel width, so that with more preferable economy；
It is applicable to deeper edpth of tunnel：The stair that run can be set to be buried to meet different tunnels according to actual conditions more
Deep, usage range is wider.
It is easier to meet requirement of the specification for safe escape：It is vertically terraced compared with common metal in the case of fire and disaster
It is safer, and with higher evacuation capacity.
Brief description of the drawings
Fig. 1 is top view of the present utility model.
Fig. 2 is A-A cut-away views in Fig. 1.
Fig. 3 is B-B cut-away views in Fig. 1.
Embodiment
In conjunction with accompanying drawing, the utility model is further described.
Embodiment 1
Referring to Fig. 1~Fig. 3, a kind of cable tunnel arranged suitable for cable bilateral, including between tunnel body, escape, it is many
Stair, cable are run, superstructure and underground structure are included between described escape；Described many race stair 3 include off stair 3-1
With at least one upper strata stair 3-2, it is characterised in that：The tongue formation escape of outwardly convex is set on the side wall of tunnel body
Between 1, provided with many race stair 3 risen toward ground in described escape.Here many race stair can be wanted according to actual buried depth
Ask, the multiple upper strata stair risen toward ground are set, to meet the requirement of escape and evacuation.
The utility model is used in the unilateral using the local form extended out of tunnel wall, forms the convex of local evagination
Groove, for accommodating 1 between stair formation escape.The more cable tunnel of existing China uses metal vertical ladder as escape opening, and shows
Atlas 15J401《Steel ladder》In 90 degree of steel vertical ladders be only applicable to the high 3.5~5.1m of ladder, if edpth of tunnel exceeds the scope not
It is applicable.And can flexibly be applied to different edpth of tunnels between the utility model escape, particularly when buried depth is deeper, by increasing
Plus stair run number, and design requirement can be still met between the utility model escape.
Further, the off stair 3-1 of described many race stair 3 is arranged at another close to tunnel body in 1 between escape
At side, the also maintenance of the cable to be arranged close to the wall of tunnel body leaves enough spaces.
Further, the cable of 1 side is uninterruptedly arranged along the wall between escape between escape, here the escape of cable edge
Between wall arrangement be exactly to realize requirement that cable is uninterruptedly arranged.
Further, the vertical plane of the tongue of described outwardly convex is trapezoidal or square or arc line shaped.As long as convex
The bending angle of groove can meet the bending radius requirement of cable installation.
Further, 1 underground structure 1-1 uses reinforced concrete structure between described escape, the ground knot between escape
Structure 1-2 uses masonry structure or light section steel structure.
Further, 1 superstructure 1-2 can set the door 2 and window 4 of varying number according to demand between described escape,
More daylightings and ventilation are provided for buried cable tunnel.
Further, sensing lamp is set in described escape.
