Abstract
The invention discloses a one-way street emergency turning-round gap bridge which is characterized by being arranged on a road insulation band; two sides of the insulation band are respectively provided with a pair of vertical columns; each pair of vertical columns are provided with steel cables; the steel cables of each pair of vertical columns are commonly connected with a blocking surface; the vertical columns are internally provided with traction motors which can be used for pulling up or putting down the blocking surfaces; the two blocking surfaces are mutually matched to form a bridge surface when being put down; and the middle of the insulation band is also provided with a supporting column for supporting the blocking surfaces when the blocking surfaces are put down. By utilizing the one-way street emergency turning-round gap bridge provided by the invention, the blocking surfaces can be put down when urgent situations of water accumulation, torrential rain, fire disasters and the like happen, and thus a turning-round channel is formed, vehicles are evacuated by turning round rapidly so as to prevent the danger caused by long-term congestion and detention.
Description
Technical field:
The present invention relates to a kind of bridge plate, particularly relate to emergent the turning around of a kind of one-way street and pass a bridge, belong to the technical field of means of transportation.
Background technology:
The through street claims again city expressway, and being has the higher speed of a motor vehicle to be long strategic road apart from transport services in the city.Main contact each major area, urban district, main suburb nearby, satellite town, main externally highway.Its specific features is: establish the median strip between roadway, forbid that pedestrian and non motorized vehicle enters express lane; Import and export and adopt full control or part control; Intersect the employing graded crossing with speedway, through street, major trunk roads; Intersect with the less secondary trunk road of the traffic volume and can adopt at grade intersection; Pass by on one's way pedestrian's concentrated setting overhead pedestrian crossing or tunnel; Design speed is 60km/h ~ 100km/h.
Speedway belongs to high-grade highway.Chinese transportation section " highway technical standard " regulation, speedway refer to " can adapt to annual mean round the clock the minibus traffic volume be more than 25000, specialize in the automobile shunting run at high speed, and whole control highways of coming in and going out ".Although various countries are different to the name of speedway, all be specially to refer to have more than 4 tracks, two travel, control fully the access, all adopt clover leaf highway to separation.In addition, have many countries to the part control the access, the clover leaf through main line of non-whole employings is also referred to as speedway.In the speedway category is also listed through main line by International Road Federation in statistics annual report over the years.The construction situation of speedway can reflect the traffic development degree of countries and regions and even the integral level of economic development.
Speedway belongs to high-grade highway.Generally can adapt to 120 kilometers/hour or higher speed, there is the width in 4 above tracks on the road surface.The centre arranges dividing strip, adopts bituminous concrete or cement concrete high class pavement, is provided with complete sign, graticule, signal and lighting device; Forbid that pedestrian and non motorized vehicle on the way walks, adopt graded crossing, pedestrian's bridge crossing or tunnel to pass through with All other routes.Can find out from definition, speedway should meet following 4 conditions in general: (1) is only for galloping; (2) be provided with multilane, median strip, will come and go traffic and separate fully; (3) be provided with plane, traffic interchange; (4) sealing completely, access control, a prospective vehicle is at some traffic interchange turnover highways of regulation.
Summary of the invention:
The technical problem to be solved in the present invention is: through street of the prior art and speedway, common feature often is provided with the isolation strip in the middle of being, the dealing vehicle is kept apart fully, even many metropolitan cities inner ring road is also taked this structure now, so no doubt so that vehicle can not arbitrarily be reversed end for end, piggybacking is overtaken other vehicles etc., standard the rule of travelling, but the problem of bringing is exactly in emergency circumstances can not reverse end for end easily, for example ponding, heavy rain etc. appear in the place ahead, even as Beijing rear flow of water rise cause danger that blocked up the heavy rain in 2012.Especially now the structure of cement steel is all adopted in a lot of isolation strip, is difficult to especially shake.
For solving the problems of the technologies described above, the invention discloses the emergent tune of a kind of one-way street and pass a bridge, concrete technical scheme is as follows:
The emergent tune of a kind of one-way street is passed a bridge, it is characterized in that: the emergent tune of described one-way street is passed a bridge and is arranged on the road separator, it respectively is provided with a column in the both sides, isolation strip, all be provided with cable wire on every column, the common obstruction face that connects on the cable wire of every column, and be provided with the traction electric machine that to stop the face pull-up or to fall in the column, two obstruction faces complemented each other to form bridge floor when falling, also be provided with the bearing post that supported described obstruction face when described obstruction face fell in the middle of described isolation strip.
Preferably, described obstruction face is made by steel plate.
Preferably, described bearing post is the height adjustable structure.
Preferably, described bearing post is jack.
Preferably, has coarse non slip surface on the described obstruction face.
Preferably, the emergent tune of described one-way street is passed a bridge and is had remote control switch.
Beneficial effect of the present invention is: utilize the emergent tune of one-way street of the present invention to pass a bridge, in the time of the emergency such as ponding, heavy rain, fire can occurring forwardly, the obstruction face that fell forms the tune passage, vehicle is evacuated in tune rapidly, is detained the danger that brings to avoid blocking up for a long time.
Description of drawings:
Fig. 1 is the schematic diagram of the emergent tune gap bridge of one-way street of the present invention when packing up;
Fig. 2 is the schematic diagram of the emergent tune gap bridge of one-way street of the present invention when falling;
Wherein, Reference numeral 1-column, the 2-cable wire, 3-stops face, 4-bearing post.
The specific embodiment:
Now by reference to the accompanying drawings the present invention is described further.
Shown in Fig. 1-2, the emergent tune of a kind of one-way street is passed a bridge, it is characterized in that: the emergent tune of described one-way street is passed a bridge and is arranged on the road separator, it respectively is provided with a column 1 in the both sides, isolation strip, all be provided with cable wire 2 on every column 1, the common obstruction face 3 that connects on the cable wire 2 of every column 1, and be provided with in the column 13 pull-ups of obstruction face or the traction electric machine that fell, two obstruction faces 3 complemented each other to form bridge floor when falling, also be provided with the bearing post 4 that supported described obstruction face 3 when described obstruction face 3 fell in the middle of described isolation strip.
