Abstract

The utility model discloses an overpass, which is especially suitable for urban roads. In order to solve the technical problem the utility model aiming to settle, the technical scheme is that: a semi-sunk four-level overpass comprises a non-motor lane on the ground, an annular driveway overhead the ground, a vertical driveway which is a channel lower than the ground and a lateral driveway which is a high cross bridge over the annular driveway. For adopting the four-level overpass, the utility model occupies less area and saves land; especially in the road construction and reconstruction in old city or old city area, the utility model can reduce demolition of building and house around and save lots of demolition cost. Meanwhile, due to compact structure and low engineering cost, the overpass can save engineering investment for a country and a construction unit.

Description

Semi-underground four aspect overpass bridges

Affiliated technical field

The utility model relates to a kind of overpass bridge, particularly is applicable to the overpass bridge of urban road.

Background technology

Along with the development of urban construction,, in urban road, adopt overpass bridge more and more in order to save the soil of an inch of land is an inch of gold.And the floor space of existing overpass bridge is very big, and it is built needs to remove and move a large amount of buildings, has therefore increased the cost and the infusion of financial resources of building.

December in 1999 notice of authorization on the 22nd the patent (patent No.: 92112156), disclose a kind of road of grade-separated junction with three diverging interconnections, but that its defective is a floor space is big, the construction costs height.

The utility model content

Technical problem to be solved in the utility model provide a kind of floor space little have an overpass bridge of four layers.

In order to realize that the technical scheme that technical problem to be solved in the utility model adopts is: semi-underground four aspect overpass bridges comprise the nonmotorized vehicle lane on the ground line, overhead annular track on ground line, vertically the track is the tunnel that is lower than ground line, and laterally the track is to make somebody a mere figurehead high overbridge above annular track.

Because the utility model has adopted the overpass bridge of four levels, so floor space is little, has saved the soil, particularly in the road construction and transformation of old city and old town, a large amount of removal expenses is saved in the building around reducing and the removal in house.Owing to the compact conformation of this overpass bridge, construction costs is low simultaneously, also can be that country and Construction unit save construction investment.

Laterally adopt through hole in the track, and on the gap bridge of nonmotorized vehicle lane, adopting half formula railing can effectively improve therebetween daylighting, reducing illumination, not only can save construction cost, can also reduce consequent maintenance cost and labour cost.

The specific embodiment

Semi-underground four aspect overpass bridges of the present utility model comprise the nonmotorized vehicle lane 1 on the ground line, overhead annular track 2 on ground line, and vertically track 3 is for being lower than the tunnel of ground line, and laterally track 4 is for making somebody a mere figurehead high overbridge above annular track 2.

Last track 6 that annular track 2 and ground line intersect and following track 9 are separately positioned on the both sides in vertical track 3 and horizontal track 4.Have a vertical through hole 5 in the center in annular track 2, through hole 5 passes the top that ground line penetrates into vertical track 3.The diameter of this through hole 5 is equal to or less than the width in vertical track 3.

Nonmotorized vehicle lane 1 adopts the following bridge opening 7 in annular track 2 and the gap bridges 8 above vertical track 3 to be interconnected.Adopt half formula railing 11 in the outside in gap bridge 8 and bridge opening 7.

Embodiment:

As shown in Figure 1, any direction road in the same way of semi-underground four aspect overpass bridges all adopts two tracks, so whole road is very spacious, each track is 3 meters, and then the road overall width of the four direction of overpass bridge is 24 meters.At the four direction of overpass bridge, the up gradient 6 in annular track 2 and gug 9 all are separately positioned on the both sides in horizontal track 4 and vertical track 3.Nonmotorized vehicle lane 1 is arranged outside around overpass bridge.When automobile need be turned right when travelling, the gug 9 that the kerb lane of the up gradient 6 by annular track 2 directly changes the right side over to travels.When automobile need turn left to travel, drive to the platform 10 in annular track 2 after, the 90 ° of gugs 9 by the left side that detour left travel.

As shown in Figures 2 and 3, nonmotorized vehicle lane 1 and the same level of ground line.Annular track 2 makes overhead on ground line about 3 meters of platform 10 by up gradient 6 and gug 9.Vertically track 3 is for being lower than the tunnel of ground line, and it is 5 meters that minimum point is lower than ground line.Laterally track 4 is for making somebody a mere figurehead high overbridge above annular track 2, and it is 5 meters that the below of the highest point in horizontal track 4 is higher than annular track 2.So laterally track 4 is sunken to the underground whole height that has reduced on the overpass bridge ground line, the height on the ground line is about 8--9 rice, can not cause big influence to the road and the environment in city.

As shown in Figures 2 and 3, for the ease of the connection around the nonmotorized vehicle lane 1, adopt the following bridge opening 7 in annular track 2 and the gap bridges 8 above vertical track 3 that nonmotorized vehicle lane 1 is interconnected.

As Fig. 3 and shown in Figure 2, have a vertical through hole 5 in the center in annular track 2, through hole 5 passes ground line and penetrates into 3 tops, vertical track, so increased the middle daylighting in tunnel in vertical track 3, and the diameter of through hole is less than or equal to the width in vertical track 3, thereby the turning radius of automobile on annular track 2 reduces, and reaches the angle of 90 ° of turnings.As shown in Figure 3, adopt half formula railing 11 in the outside of the gap bridge 8 of nonmotorized vehicle lane 4 and the outside in bridge opening 7, increased pass a bridge 8 around daylighting.

Under the influence that is subjected to urban road and surrounding enviroment, change the track into the bicycle road, the structure of whole overpass bridge is compact more.In like manner, at the crossing that main line and branch line cross, vertically track 3 or laterally track 4 change the bicycle road into, also belong to protection domain of the present utility model.
