Abstract
The utility model relates to an anti-explosion separation structure between two tunnels. A communication passageway is arranged between the two bi-directional parallel tunnels, and a separation facility which is convenient to open, resistant to explosion and smokeproof is needed. According to the anti-explosion separation structure between the two tunnels, reinforcing liners are arranged at the two ends of the communication passageway and the inner end of a lining of the communication passageway, reinforced concrete door frame walls are arranged at the inner ends of the reinforcing liners, each reinforced concrete door frame wall is provided with a pre-embedded steel door frame, and an anti-explosion door is arranged on each pre-embedded steel door frame; a strengthened reinforcement bar hidden beam is transversely arranged above each reinforced concrete door frame wall, and a top cavity plugging part grouted by the reinforced concrete is arranged between the portion above each strengthened reinforcement bar hidden beam and each reinforcing liner; a small open roof screed is arranged at the bottom of each reinforced concrete door frame wall. The anti-explosion separation structure between the two tunnels is convenient to open, can achieve the anti-explosion function and the smokeproof function, and is simple to construct, convenient to overhaul, and reliable in safety.
Description
Technical field
the utility model belongs to tunnel traffic field of engineering technology, is specifically related to explosion-proof partition-type structures between a kind of two tunnels.
Background technology
Great development along with traffic engineering such as China railways, highways, the tunnel quantity of building in mountain area rolls up, wherein very large in the accounting of mountain area long tunnel (railway tunnel length is greater than 3 kilometers, highway tunnel length and is greater than 1 kilometer), super long tunnel (railway tunnel length is greater than 10 kilometers, highway tunnel length and is greater than 3 kilometers), greatly improved operation condition.And the safety during runing is also had higher requirement for tunnel, generally be designed to two parallel tunnels for this reason, the transportation of taking on respectively both direction, during as situations such as tunnel wherein has an accident, fire, blasts, another tunnel can maintain and be open to traffic, by the service channel between two tunnels, play the effect of rescue, evacuation simultaneously.Therefore a kind ofly in service channel open conveniently, simultaneously again can the explosion-proof partition facility every cigarette most important, so just can avoid the disaster of a generation tunnel in to bring disaster to another tunnel, the while, personnel can flee from safety area again fast.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly opens conveniently, can be explosion-proof every between two tunnels of cigarette explosion-proof partition-type structures.
The technical scheme that the utility model adopts is:
An explosion-proof partition-type structures between two tunnels, is characterized in that:
In between two tunnels, the inner end of the two ends of service channel, the lining cutting of service channel own arranges reinforcement liner, strengthen liner inner end and be provided with steel concrete door frame wall, on steel concrete door frame wall, be provided with pre-buried steel door frame, on pre-buried steel door frame, explosion proof door be installed;
Steel concrete door frame wall top is horizontal the dark beam of the arrangement of reinforcement of reinforcement, strengthens the dark beam of arrangement of reinforcement top to the top cavity shutoff of strengthening being provided with between liner steel concrete perfusion;
Steel concrete door frame wall bottom is provided with little open roof screed.
The central authorities of top cavity shutoff are provided with for the reserved plain concrete lining cutting of blower fan of blower fan is installed.
Reinforcement liner is 3-5 rice along the scope of service channel direction.
Little open roof screed is 1.5 meters along the scope of service channel direction.
The utlity model has following advantage:
The utility model construction and easy for installation, in the service channel of appropriate location, a tunnel, partition-type structures being set, arranges two places in each passage.The service channel that partition-type structures place is set is strengthened to one deck steel concrete liner, door frame wall is set, by pre-buried steel door frame, sizing explosion proof door is installed, explosion proof door meets opposing according to the shock wave producing after the blast of tunnel transporting cargo type type, explosion proof door door leaf is single fan, to the vertical turn-off of shock wave arrival bearing, open, door leaf and locking are manual opening-closing.Doorframe top arranges the dark beam of strengthening arrangement of reinforcement, and on it, cavity adopts steel concrete shutoff.On door leaf, must eye-catchingly indicate door leaf open and close direction and latch handle (or handwheel) open and close direction, can singlely open.All models steel are all done antirust processing, have the plurality of advantages such as construction is simple, maintenance is convenient, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the utility model plan view.
Fig. 2 is the utility model A-A sectional drawing.
Fig. 3 is the utility model B-B sectional drawing.
In figure, the lining cutting of 1-service channel own, 2-steel concrete door frame wall, 3-strengthens liner, the pre-buried steel door frame of 4-, 5-explosion proof door, 6-strengthens the dark beam of arrangement of reinforcement, the cavity shutoff of 7-top, the little open roof screed of 8-, 9-blower fan is reserved plain concrete lining cutting, 10-Cable Groove, 11-ditch, 12-communicaton and signal cable groove.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in detail.
The utility model relates to explosion-proof partition-type structures between a kind of two tunnels, in between two tunnels, the inner end of the two ends of service channel, the lining cutting 1 of service channel own arranges and strengthens liner 3, near appropriate location, two tunnels, reinforcement liner 3 is 3-5 rice along the scope of service channel direction respectively.Strengthen liner 3 inner ends and be provided with steel concrete door frame wall 2, on steel concrete door frame wall 2, be provided with pre-buried steel door frame 4, on pre-buried steel door frame 4, explosion proof door 5 is installed, carry out sealing.
Steel concrete door frame wall 2 tops are horizontal the dark beam 6 of the arrangement of reinforcement of reinforcement, strengthens the dark beam of arrangement of reinforcement 6 tops to the top cavity shutoff 7 of strengthening being provided with between liner 3 steel concrete perfusion.Steel concrete door frame wall 2 bottoms are provided with little open roof screed 8, along the scope of service channel direction, are 1.5 meters, and anti-sealing, oil are overflow to low threaded list road by high tunnel.The central authorities of top cavity shutoff 7 are provided with for the reserved plain concrete lining cutting 9 of blower fan of blower fan is installed.
It is cited that content of the present utility model is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model manual, is claim of the present utility model and contains.
