Abstract
The utility model discloses a miniature tunnel, including tunnel road surface (4), tunnel top (5), tunnel side (6), canopy (10) and no canopy guardrail (11), tunnel road surface (4), tunnel top (5) and tunnel side (6) are pre -fabricated steel frame or steel concrete structure, in laying behind the on -site Assembly in by tunnel mounting groove side elevation inoxidizing coating (2) and tunnel mounting groove bottom surface inoxidizing coating (3) common flute profile space that constitutes. Because the main part of urban traffic flow is the dilly, implements in intersection necessary also with good conditionsi the utility model discloses, can make the craspedodrome dilly of a pair of orientation realize three -dimensional currently to reduce this and take vehicle sum of keeping straight on on the road surface to the orientation, and then shorten this craspedodrome green lamp time to the orientation, will distribute to more times this to the turning left and other orientations of orientation, thereby improve crossing capacity, effectively alleviate urban traffic and block up, the weak point is with low costs the time limit for a project simultaneously, does not also influence the appearance of the city.
Description
Technical field
This utility model is related to road traffic technology, refers specifically to urban road crossing multilevel traffic.
Background technology
The congestion of urban transportation is primarily not to cause by road but by the deficiency of intersection capacity, often in fact
Rule solution is to build viaduct or tunnel at crossing, but both of which cost long in time limit is high, and viaduct also hinders the appearance of the city.
Utility model content
For solving above technical problem, the utility model discloses a kind of micro-tunneling, including tunnel road surface, tunnel top
Portion, tunnel side, awning and no awning guardrail, described tunnel road surface, tunnel top and tunnel side be Prefabricated steel construction or
Reinforced Concrete Structure, is placed in common by tunnel mounting groove side elevation overcoat and tunnel installation groove bottom overcoat after Assembling
In the channel space constituting；Described tunnel road surface only supplies dilly to pass through, and described tunnel top is concordant with ground, and described
Guarantee under the support of tunnel side that heavy vehicle passes through.
Preferably, when using described awning, tunnel arranges natural drainage facility, and the porch setting in ramp is slowed down
Water fender.
Preferably, when using described no awning guardrail, tunnel arranges forced drainage facility.
Beneficial effect：Because the main body of Forecast of Urban Traffic Flow is dilly, it is being necessary also conditional intersection
Implement this utility model, the straight trip dilly in a pair of direction can be made to realize three-dimensional current, thus reduce this taking to direction
The vehicle fleet of road surface straight trip, and then shorten this straight trip green time to direction, the more time is distributed to this to direction
Turn left and other direction, thus improving going through ability, effectively alleviation urban traffic blocking, short time limit low cost simultaneously,
Do not affect the appearance of the city.

Specific embodiment
As shown in figure 1, micro-tunneling only supplies dilly to pass through, but the master of dilly exactly Forecast of Urban Traffic Flow
Body.Continuously pass through because multilevel traffic can guarantee that, tunnel arranges two-way two-way traffic and can ensure the preferable traffic capacity, therefore tunnel
The span width of road surface 4 is set to 5.5-6 rice；Its tunnel top concordant with ground 15 is just being also used for vehicle and pedestrian
Normal open row.And Prefabricated steel construction or Reinforced Concrete Structure are placed in after assembling at the scene and can excavate rapidly in the tunnel mounting groove of lining cutting,
The required duration is very short.
As shown in Fig. 2 because micro-tunneling is only used for passing through intersection, the length of tunnel road surface 4 is not shorter than 24 meters i.e.
The tunnel top 5 that equal length can be made ensures two-way six car lanes and necessary bicycle lane and footpath, this length
Also micro-tunneling is made need not to be equipped with forced ventilation mechanism；Due to only allowing dilly to pass through and without forced ventilation mechanism,
Tunnel clear height is set as 2 meters, and this height is also sufficient for pick up such small rescue vehicle and enters, vehicle
Convenient rescue when fault or vehicle accident.
The clear height in tunnel is relatively low, and the ramp 9 of access tunnel can also be very short on the premise of keeping the reasonable gradient, saves
Take the area on ground 7.
For reducing the material risk of tunnel hydrops and simplifying draining, ramp 9 should arrange awning 10, and ramp 9 and ground 7
Joint should arrange deceleration water fender 8, and dash is simultaneous to slow down, but tunnel bottom must arrange hydrops alarm device to prohibit in hydrops
Only current, thus preventing accident；If local rainwater is less or can not accept that awning 10 is this to seem setting of independent subway entrance
Apply the limited impact on the appearance of the city it is also possible to arrange no awning guardrail 11, but now need to be equipped with powerful reliable automatic forced draining
Facility.
Because in closing space, the requirement to safety is higher than open spaces, therefore will be on ramp 9 and tunnel road surface 4
Continuous deceleration strip should be set, allow motor vehicles to be difficult to current at a high speed, also allow non-motor vehicle be difficult to pass through；Tunnel planted agent setting prison
Control, houselights, warning light and hydrops alarm signal；Tunnel portal setting height-limiting bar and sign board prevent overrun vehicle from sailing
Enter；Because this micro-tunneling is cheap, even if it is worth to configure a special rescue pick up near each tunnel.
It is being necessary also conditional crossing, the large-scale crossing that such as two major trunk roads intersect, according to all directions traffic flow
Amount, all directions exceed the ratio of vehicle, the existing width of roadway of all directions and the underground pipe network situation of micro-tunneling boundary, Ke Yiling
Live and arrange the direction of micro-tunneling；By Prefabricated steel construction or Reinforced Concrete Structure and Assembling, excavate rapidly and harden ramp and
Lay the mounting groove in tunnel, can be controlled the engineering time within these few days, in addition Friday evening peak to Monday morning peak it
Between.
Congestion in the many city of China not whole city congestion but in some large-scale intersection congestions, and these are large-scale
Also have ready conditions enforcement this utility model in intersection itself, thus by low cost, casual labourer's phase, take up an area less, do not hinder the appearance of the city in the way of
Solve congestion focus it is ensured that rush-hour whole city unimpeded；Even if in non-peak period, this utility model is also beneficial to shorten and leads to
The row time, thus reducing the necessity building more conventional express passway, save construction fund.
