Abstract
Description
Technical Field
[0001] This application relates to the field of urban interchange technology, and in particular to an interchange that can be quickly constructed on a roadway. Background Technology
[0002] In today's increasingly busy road traffic, especially in urban roads, ensuring smooth traffic flow has become an important issue in urban management, and the key to smooth urban road traffic lies in whether road intersections are unobstructed.
[0003] Currently, smooth traffic flow at urban intersections is mainly achieved through traffic lights and grade-separated interchanges.
[0004] The construction cost of grade-separated interchange bridges is too high, they occupy a large area, and the construction period is long. In particular, they are limited by many factors such as the land area, so they cannot be widely used and are only used at intersections that are particularly busy or have high traffic pressure.
[0005] Therefore, traffic lights remain the primary means of traffic management at intersections. When the light is red, vehicles must stop and wait for the green light. In large and medium-sized cities with heavy traffic, vehicles often line up from one intersection to the next, with speeds below 5 kilometers per hour, and traffic jams frequently occur.
[0006] In addition, in some special circumstances, such as emergency road repairs, or when there is a short-term need to alleviate traffic pressure through interchanges, it is urgent to quickly build interchanges to ensure smooth road traffic. Summary of the Invention
[0007] This application provides a grade-separated interchange that can be quickly constructed on a roadway, in order to solve the problems of high construction costs, large land occupation, long construction periods, and frequent traffic jams caused by traffic lights in the related technologies for urban intersection grade-separated interchanges.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] This application provides a grade-separated interchange that can be quickly constructed on a roadway, which can solve the problems of high construction cost, large land occupation, long construction period, and frequent traffic jams caused by traffic lights in the related technologies for urban intersection grade-separated interchange bridges.
[0025] See Figures 1 to 4 As shown, this application embodiment provides a grade-separated interchange that can be quickly constructed on a lane, the grade-separated interchange comprising: The main girder 10 of the overpass includes an outer girder segment 11 and an inner girder segment 12 that are slidably connected to each other. The inner girder segment 12 is located inside the outer girder segment 11 and can move slidably along the length of the outer girder segment 11.
[0026] When the main beam 10 of the overpass is in storage or transportation, the inner segment 12 of the main beam retracts into the outer segment 11 of the main beam, which can significantly shorten the total length of the main beam 10 of the overpass, reduce the land area occupied and facilitate vehicle transportation.
[0027] When the main girder 10 of the overpass is in operation at the intersection, the inner segment 12 of the main girder extends at least partially beyond the outer segment 11 of the main girder, thereby significantly increasing the total length of the main girder 10 of the overpass and enabling it to span over multiple lanes.
[0028] The overpass ramp 20 includes an uphill ramp 21 and a downhill ramp 22 located at both ends of the main beam 10 and connected to the outer segment 11 and the inner segment 12 of the main beam, respectively. Both the uphill ramp 21 and the downhill ramp 22 include an upper ramp segment 23 and a lower ramp segment 24 that are mutually telescopically connected.
[0029] When the overpass ramp 20 is in storage or transportation mode, the lower segment 24 of the uphill ramp 21 and the downhill ramp 22 is retracted into the upper segment 23 of the ramp, which can significantly shorten the total length of the uphill ramp 21 and the downhill ramp 22, reduce the land area occupied and facilitate vehicle transportation.
[0030] When the overpass ramp 20 is in operation at the intersection, the lower segment 24 of the uphill ramp 21 and the downhill ramp 22 extends at least partially beyond the upper segment 23, thereby significantly increasing the total length of the uphill ramp 21 and the downhill ramp 22 and reducing the gradient for vehicles or pedestrians going up and down the bridge.
[0031] The overpass pier 30 includes a main beam pier 31 that vertically supports the main beam 10 of the overpass, and a ramp pier 32 that vertically supports the overpass ramp 20. The heights of the main beam pier 31 and the ramp pier 32 are adjustable.
[0032] The main beam pier 31 is used to vertically support the main beam 10 of the overpass, and the height of the main beam pier 31 is adjustable to support the main beam 10 of the overpass at a set height above the road. The ramp pier 32 is used to vertically support the overpass ramp 20, and the height of the ramp pier 32 is adjustable to adjust the slope of the overpass ramp 20.
[0033] The height of the main beam pier 31 and the ramp pier 32 is adjustable. When the main beam 10 and the ramp 20 of the overpass are in storage or transportation, the main beam pier 31 and the ramp pier 32 of the overpass pier 30 are retracted or folded to the lowest height, reducing the total height of the main beam 10 and the ramp 20 of the overpass.
[0034] The main girder 10 of the interchange, which is rapidly constructed on the roadway in this embodiment, includes an outer girder segment 11 and an inner girder segment 12 that are mutually telescopically connected. Both the uphill ramp 21 and the downhill ramp 22 include an upper ramp segment 23 and a lower ramp segment 24 that are mutually telescopically connected. The interchange piers 30 include main girder piers 31 that vertically support the main girder 10 and ramp piers 32 that vertically support the ramps 20. The heights of the main girder piers 31 and the ramp piers 32 are adjustable.
[0035] The outer segment 11 and inner segment 12 of the main girder 10 of the overpass, as well as the upper segment 23 and lower segment 24 of the uphill ramp 21 and downhill ramp 22, are assembled into a collapsed state after being prefabricated in the factory (see...). Figure 3 and Figure 4 As shown), the entire unit can be transported to a traffic intersection using a telescopic semi-trailer truck for quick ground-mounted installation (see...). Figure 1 and Figure 2 (As shown).
[0036] This application can alleviate traffic pressure in a timely manner by transporting it to the site and quickly constructing a three-dimensional road network. Pedestrians or vehicles can quickly cross the ground lanes without waiting for traffic lights, thereby helping to make urban traffic smoother.
[0037] In some alternative embodiments: see Figures 1 to 4 As shown in the figure, this application embodiment provides a grade-separated interchange that can be quickly constructed on a roadway. The outer segment 11 of the main beam of the grade-separated interchange includes a first upper bridge deck 111 and a first lower bridge deck 112, as well as a plurality of first web members 113 connecting the first upper bridge deck 111 and the first lower bridge deck 112. The first upper bridge deck 111, the first lower bridge deck 112, and the plurality of first web members 113 together enclose a first driving space.
[0038] The main beam segment 12 includes a second upper bridge deck 121 and a second lower bridge deck 122, as well as multiple second web members 123 connecting the second upper bridge deck 121 and the second lower bridge deck 122. The second upper bridge deck 121, the second lower bridge deck 122, and the multiple second web members 123 together enclose a second driving space. The cross-sections of the first driving space and the second driving space are both rectangular structures and are interconnected.
[0039] The second lower bridge deck 122 is located above the first lower bridge deck 112 and is parallel to it. The second upper bridge deck 121 is located below the first upper bridge deck 111 and is parallel to it. A lower ramp 13 is provided at the connection between the first lower bridge deck 112 and the second lower bridge deck 122, and an upper ramp 14 is provided at the connection between the first upper bridge deck 111 and the second upper bridge deck 121.
[0040] The first lower bridge deck 112, the lower ramp 13, and the second lower bridge deck 122 together form a motor vehicle lane, which is used by cars to quickly cross the lane below without waiting for traffic lights. The first upper bridge deck 111, the upper ramp 14, and the second upper bridge deck 121 together form a non-motorized vehicle lane or pedestrian lane, which is used by pedestrians or non-motorized vehicles to quickly cross the lane below without waiting for traffic lights.
[0041] In this embodiment, the first lower bridge deck 112, the lower ramp 13, and the second lower bridge deck 122 together form a motor vehicle lane, while the first upper bridge deck 111, the upper ramp 14, and the second upper bridge deck 121 together form a non-motor vehicle lane or pedestrian lane. Therefore, the interchange of this application can achieve two-level traffic flow, with the lower motor vehicle lane for one-way car traffic and the upper non-motor vehicle lane or pedestrian lane for pedestrians and non-motorized vehicles.
[0042] In some alternative embodiments: see Figures 1 to 4 As shown in the figure, this application embodiment provides a grade-separated interchange that can be quickly constructed on a roadway. The top surface of the first lower bridge deck 112 of the interchange is provided with a guide rail 114 that slidably connects to the second lower bridge deck 122. The bottom of the second lower bridge deck 122 is provided with a plurality of sliding wheel sets 124 arranged along the length direction of the guide rail 114. Safety guardrails 15 are provided on both sides of the top surface of the first upper bridge deck 111 and the second upper bridge deck 121.
[0043] In this embodiment, a guide rail 114 for sliding connection to a second lower bridge deck 122 is provided on the top surface of the first lower bridge deck 112, and a plurality of sliding wheel sets 124 arranged along the length direction of the guide rail 114 are provided on the bottom of the second lower bridge deck 122. The inner segment 12 of the main beam can flexibly extend and retract within the outer segment 11 of the main beam through the sliding wheel sets 124 and the guide rail 114, thereby reducing the resistance of the inner segment 12 of the main beam extending and retracting within the outer segment 11 of the main beam.
[0044] In some alternative embodiments: see Figures 1 to 4 As shown in the embodiment of this application, an interchange that can be quickly constructed on a lane is provided. The interchange has two sets of uphill ramps 21, namely uphill ramps 211 for motor vehicles and uphill ramps 212 for non-motor vehicles, and two sets of downhill ramps 22, namely downhill ramps 221 for motor vehicles and downhill ramps 222 for non-motor vehicles.
[0045] The motor vehicle uphill ramp 211 is rotatably connected to the end of the first lower bridge deck 112, and the non-motor vehicle uphill ramp 212 is rotatably connected to the end of the first upper bridge deck 111. The motor vehicle downhill ramp 221 is rotatably connected to the end of the second lower bridge deck 122, and the non-motor vehicle downhill ramp 222 is rotatably connected to the end of the second upper bridge deck 121.
[0046] In this embodiment, the motor vehicle uphill ramp 211 is connected to the first lower bridge deck 112 and is located away from the end of the second lower bridge deck 122, and the motor vehicle downhill ramp 221 is connected to the second lower bridge deck 122 and is located away from the end of the first lower bridge deck 112.
[0047] Cars enter the first lower bridge deck 112 and the second lower bridge deck 122 sequentially via the uphill ramp 211, and then exit the overpass via the downhill ramp 221. Pedestrians or non-motorized vehicles enter the first upper bridge deck 111 and the second upper bridge deck 121 sequentially via the uphill ramp 212, and then exit the overpass via the downhill ramp 222.
[0048] In this embodiment, the length directions of the motor vehicle uphill ramp 211, the first lower bridge deck 112, the second lower bridge deck 122, and the motor vehicle downhill ramp 221 are parallel to each other. The length directions of the non-motor vehicle uphill ramp 212 and the non-motor vehicle downhill ramp 222 are perpendicular to or intersect with the length directions of the first upper bridge deck 111 and the second upper bridge deck 121, thereby spatially avoiding the motor vehicle uphill ramp 211 and the motor vehicle downhill ramp 221 and preventing mutual interference in position.
[0049] In some alternative embodiments: see Figures 1 to 4 As shown, this application embodiment provides a grade-separated interchange that can be quickly constructed on a lane. The upper segment 23 of the motor vehicle uphill ramp 211 of the grade-separated interchange is connected to the end of the first lower bridge deck 112 by a first hinge 214. The axis of the first hinge 214 is parallel to the width direction of the main beam 10 of the overpass.
[0050] The upper segment 23 of the motor vehicle uphill ramp 211 is rotatably connected to the end of the first lower bridge deck 112 via the first hinge 214, thereby allowing the motor vehicle uphill ramp 211 to rotate up and down relative to the first lower bridge deck 112 with the first hinge 214 as the axis of rotation, thus allowing the slope of the motor vehicle uphill ramp 211 to be flexibly adjusted.
[0051] The upper segment 23 of the downhill ramp 221 for motor vehicles is connected to the end of the second lower bridge deck 122 by a second hinge 224. The axis of the second hinge 224 is parallel to the width direction of the main beam 10 of the overpass.
[0052] The upper segment 23 of the motor vehicle downhill ramp 221 is rotatably connected to the end of the second lower bridge deck 122 via the second hinge 224, thereby allowing the motor vehicle downhill ramp 221 to rotate up and down relative to the second lower bridge deck 122 with the second hinge 224 as the pivot, thus allowing the slope of the motor vehicle downhill ramp 221 to be flexibly adjusted.
[0053] The upper segment 23 of the non-motorized vehicle uphill ramp 212 is connected to the end of the first upper bridge deck 111 by a third hinge 213. The third hinge 213 is provided with two mutually perpendicular rotating shafts, so that the rotation axis of the third hinge 213 can rotate not only around the height direction of the main beam 10 of the overpass, but also around the horizontal direction of the main beam 10 of the overpass.
[0054] The upper segment 23 of the non-motorized vehicle uphill ramp 212 is rotatably connected to the first upper bridge deck 111 via the third hinge 213, thereby allowing the non-motorized vehicle uphill ramp 212 to freely rotate up and down relative to the first upper bridge deck 111 with the third hinge 213 as the axis of rotation, thus allowing for flexible adjustment of the slope of the non-motorized vehicle uphill ramp 212.
[0055] In addition, the upper segment 23 of the non-motorized vehicle uphill ramp 212 is rotatably connected to the first upper bridge deck 111 via the third hinge 213, thereby allowing the non-motorized vehicle uphill ramp 212 to rotate freely left and right relative to the first upper bridge deck 111 with the third hinge 213 as the axis of rotation, thereby flexibly adjusting the deflection angle between the non-motorized vehicle uphill ramp 212 and the first upper bridge deck 111.
[0056] When the non-motorized vehicle uphill ramp 212 is in storage or transport mode, the third hinge 213 is used to adjust the length direction of the non-motorized vehicle uphill ramp 212 to keep it parallel to the length direction of the first upper bridge deck 111 (see...). Figure 3 and Figure 4 (As shown). When the non-motorized vehicle uphill ramp 212 is in operation, the length direction of the non-motorized vehicle uphill ramp 212 is adjusted by the third hinge 213 to maintain an intersection with the length direction of the first upper bridge deck 111, such that the angle between the two in the height direction projection is 90° (see...). Figure 1 and Figure 2 (As shown).
[0057] The upper segment 23 of the non-motorized vehicle downhill ramp 222 is connected to the end of the second upper bridge deck 121 by a fourth hinge 223. The fourth hinge 223 is provided with two mutually perpendicular rotating shafts, so that the rotation axis of the fourth hinge 223 can rotate not only around the height direction of the main beam 10 of the overpass, but also around the horizontal direction of the main beam 10 of the overpass.
[0058] The upper segment 23 of the non-motorized vehicle downhill ramp 222 is rotatably connected to the second upper bridge deck 121 via the fourth hinge 223, thereby allowing the non-motorized vehicle downhill ramp 222 to freely rotate up and down relative to the second upper bridge deck 121 with the fourth hinge 223 as the axis of rotation, thus allowing the slope of the non-motorized vehicle downhill ramp 222 to be flexibly adjusted.
[0059] In addition, the upper segment 23 of the non-motorized vehicle downhill ramp 222 is rotatably connected to the second upper bridge deck 121 via the fourth hinge 223, which allows the non-motorized vehicle downhill ramp 222 to rotate freely about the fourth hinge 223 relative to the second upper bridge deck 121, thereby flexibly adjusting the deflection angle between the non-motorized vehicle downhill ramp 222 and the second upper bridge deck 121.
[0060] When the non-motorized vehicle downhill ramp 222 is in storage or transport mode, the fourth hinge 223 is used to adjust the length direction of the non-motorized vehicle downhill ramp 222 to keep it parallel to the length direction of the second upper bridge deck 121 (see...). Figure 3 and Figure 4 (As shown). When the non-motorized vehicle downhill ramp 222 is in operation, the length direction of the non-motorized vehicle downhill ramp 222 is adjusted by the fourth hinge 223 to maintain an intersection with the length direction of the second upper bridge deck 121, such as an angle of 90° in the height direction projection (see...). Figure 1 and Figure 2 (As shown).
[0061] In some alternative embodiments: see Figures 1 to 4 As shown, this application embodiment provides a grade-separated interchange that can be quickly constructed on a lane. The upper segment 23 of the interchange has guide grooves on both sides to accommodate and slide the lower segment 24 of the ramp. The two sides of the lower segment 24 slide along the length direction of the upper segment 23 of the ramp within the guide grooves.
[0062] The bottom or sides of the upper segment 23 of the ramp are connected to a winch 25. The winch 25 is connected to the lower segment 24 of the ramp by a steel wire rope. The winch 25 drives the lower segment 24 of the ramp to slide on the upper segment 23 of the ramp by winding and unwinding the steel wire rope.
[0063] The top surfaces of both the upper segment 23 and the lower segment 24 of the ramp are covered with anti-slip reinforcement. Safety guardrails 15 are installed on both sides of the top surfaces of the upper segment 23 and the lower segment 24 of the ramp. The safety guardrails 15 are detachably connected to the upper segment 23 and the lower segment 24 of the ramp.
[0064] In this embodiment, the lower ramp segment 24 is located within the guide groove of the upper ramp segment 23 and slides along the length of the upper ramp segment 23, allowing the lower ramp segment 24 to flexibly switch between a retracted and extended state. The extension of the lower ramp segment 24 can change the slope of the ascending ramp 21 and the descending ramp 22, while the retraction of the lower ramp segment 24 facilitates vehicle transportation.
[0065] A winch 25 is connected to the bottom or both sides of the upper segment 23 of the ramp. The winch 25 drives the lower segment 24 of the ramp to slide and extend on the upper segment 23 by winding and unwinding a steel wire rope, thereby facilitating the adjustment of the extension length of the lower segment 24 and improving on-site construction efficiency. The winch 25 can be a manual winch or an electric winch, depending on whether power is provided at the construction site.
[0066] In some alternative embodiments: see Figures 1 to 4 and Figure 7 As shown in the embodiment of this application, a grade-separated bridge that can be quickly constructed on a roadway is provided. The main beam pier 31 and the ramp pier 32 of the grade-separated bridge both include upper pier segments and lower pier segments 306 that are telescopically connected and / or hinged to each other. The top of the upper pier segment is provided with a hinge seat, which is rotatably connected to the main beam 10 of the overpass or the overpass ramp 20 through a rotating shaft. The bottom of the lower pier segment 306 is provided with a flange.
[0067] The upper pier segment comprises an inner segment 302 and an outer segment 301 that are coaxially and slidably connected. Multiple positioning holes 303 are provided on both the inner segment 302 and the outer segment 301, spaced apart along their axial direction. Both the inner segment 302 and the outer segment 301 are hollow structures, and a telescopic cylinder 304 is provided between them.
[0068] The top of the telescopic cylinder 304 is connected to the top of the inner segment 302 of the upper pier, and the bottom of the telescopic cylinder 304 is connected to the bottom of the outer segment 301 of the upper pier. The telescopic cylinder 304 adjusts its own length to realize the telescopic movement of the inner segment 302 of the upper pier within the outer segment 301 of the upper pier, thereby adjusting the height of the upper pier segment.
[0069] When the telescopic cylinder 304 adjusts its own length to achieve the telescopic movement of the inner segment 302 of the upper pier column within the outer segment 301 of the upper pier column to the set height, and the positioning holes 303 on the inner segment 302 and the outer segment 301 of the upper pier column are concentric, the positioning pin is inserted into the positioning holes 303 on the inner segment 302 and the outer segment 301 of the upper pier column to achieve height positioning.
[0070] The top of the lower pier segment 306 is connected to the bottom of the upper pier outer segment 301 by a hinge 307. The lower pier segment 306 rotates up and down relative to the upper pier outer segment 301 with the hinge 307 as the pivot, thereby realizing the folding and supporting action of the lower pier segment 306.
[0071] A fine-tuning mechanism 305 is provided at the top of the inner segment 302 of the upper pier column. The fine-tuning mechanism 305 consists of a screw and a nut connected to each other. The hinge is connected to the top of the screw. By adjusting the rotation of the nut relative to the screw, the extension length of the screw can be adjusted, thereby precisely controlling the support height of the main beam pier 31 and the ramp pier 32.
[0072] In some alternative embodiments: see Figure 5 and Figure 6 As shown in the illustration, this application provides a grade-separated interchange that can be quickly constructed on a roadway. The interchange has two or more sets of these sets, which are parallel to each other and symmetrically spaced. Steel bridge decks 40 connect adjacent sets of interchanges. There are two or more sets of steel bridge decks 40, one set spanning the ends of the outer segments 11 of two adjacent main beams, and the other set spanning the ends of the inner segments 12 of two adjacent main beams. Safety railings 15 are connected to both sides of the steel bridge decks 40.
[0073] The interchange in this embodiment has two or more sets, which are symmetrically spaced apart. The two or more sets of interchanges are respectively erected on two lanes with the same or opposite directions of traffic. In order to facilitate the travel of non-motorized vehicles and pedestrians on the two sets of interchanges, steel bridge plates 40 are built on the adjacent two sets of interchanges. Pedestrians and non-motorized vehicles can reach the other three intersections from any intersection, which greatly facilitates the passage of pedestrians and non-motorized vehicles.
[0074] This application's embodiments are not limited to installing two sets of interchanges at a single intersection. The specific number of interchanges is determined based on the number of lanes and traffic congestion. More lanes and less traffic congestion allow for an increase in the number of interchanges, thus improving vehicle throughput. For example, two sets of interchanges can be installed on-site for a two-way four-lane road; two, three, or four sets can be installed on a two-way six-lane road; and two, three, four, five, or six sets of interchanges can be installed on a two-way eight-lane road. Lanes without interchanges are left-turn lanes, right-turn lanes, or straight-through lanes for large trucks.
[0075] All components of the interchange that can be quickly erected on the roadway in this embodiment are manufactured in the factory. After initial assembly in the factory, the main beam 10, the ramp 20 and the pier 30 of the overpass are connected to each other as a whole and are all in a retracted or folded state to reduce their size and facilitate transportation of the whole to the destination by transport vehicles.
[0076] The overpass, consisting of the main beam 10, the ramp 20, and the pier 30, is hoisted onto the telescopic semi-trailer truck, which then transports the entire structure to the installation location at the intersection.
[0077] Telescopic semi-trailer trucks are a specialized vehicle system consisting of a tractor unit and an adjustable-length telescopic semi-trailer. The telescopic structure adapts to different cargo sizes, improving transportation flexibility.
[0078] The core feature of these vehicles is that the semi-trailer chassis is equipped with a telescopic mechanism, such as a pull-out flatbed design, which can change the overall length to facilitate the transport of oversized or standard-sized goods. Common types include low-bed semi-trailers, flatbed semi-trailers, and ramp semi-trailers, suitable for transporting large items such as construction machinery, steel, bridges, and wind turbine blades.
[0079] When the telescopic semi-trailer truck transports the overpass, consisting of the main beam 10, the overpass ramp 20, and the overpass pier 30, to the construction site, it uses the telescopic mechanism equipped on the telescopic semi-trailer truck itself to extend the inner segment 12 of the main beam 10 from the outer segment 11 of the main beam to a set length, and then fixes the inner segment 12 of the main beam to the outer segment 11 of the main beam with fasteners.
[0080] Using the lifting mechanism (such as a lifting hydraulic cylinder) provided by the telescopic semi-trailer truck itself, the inner segment 12 and outer segment 11 of the main beam of the overpass 10, as well as the overpass ramp 20, are lifted upwards, so that they are removed from the top surface of the telescopic semi-trailer truck. Then, the overpass pier 30 is extended downwards and used to switch the support of the inner segment 12, outer segment 11 and overpass ramp 20.
[0081] After the telescopic semi-trailer truck's own lifting mechanism (such as a lifting hydraulic cylinder) retracts, the driver can adjust the extension, slope, and direction angle of the overpass ramp 20 after driving the telescopic semi-trailer truck away from the overpass. After the above construction steps are completed, the overpass piers 30 are fixed to the road surface, and the truck can then participate in normal traffic operations.
[0082] Working principle This application provides a grade-separated interchange that can be quickly erected on a lane. The grade-separated interchange of this application is equipped with a main beam 10, which includes an outer segment 11 and an inner segment 12 that are slidably connected to each other. The inner segment 12 is located inside the outer segment 11 and moves slidably along the length of the outer segment 11.
[0083] The overpass ramp 20 includes an uphill ramp 21 and a downhill ramp 22 located at both ends of the main beam 10 and connected to the outer segment 11 and the inner segment 12 of the main beam, respectively. Both the uphill ramp 21 and the downhill ramp 22 include an upper ramp segment 23 and a lower ramp segment 24 that are mutually telescopically connected.
[0084] The overpass pier 30 includes a main beam pier 31 that vertically supports the main beam 10 of the overpass, and a ramp pier 32 that vertically supports the overpass ramp 20. The heights of the main beam pier 31 and the ramp pier 32 are adjustable.
[0085] Therefore, the main beam 10 of the overpass in the rapid construction of the overpass in this application includes an outer segment 11 and an inner segment 12 of the main beam that are mutually telescopically connected. The uphill ramp 21 and the downhill ramp 22 both include an upper segment 23 and a lower segment 24 of the ramp that are mutually telescopically connected.
[0086] After the outer segment 11 and inner segment 12 of the main beam of the overpass 10, as well as the upper segment 23 and lower segment 24 of the ramps of the uphill ramp 21 and downhill ramp 22, are prefabricated in the factory and assembled into a retractable state, they can be transported as a whole to the intersection by a telescopic semi-trailer truck to quickly complete the ground extension installation.
[0087] This application can quickly construct a three-dimensional road network on-site to alleviate traffic congestion, allowing pedestrians or vehicles to cross the ground lanes directly without waiting for traffic lights, thus contributing to smoother urban traffic.
