Description

Technical Field

[0001] The present invention relates to the technical field of bridge erection, and more particularly to a method for rapidly erecting a bridge across a high embankment highway. Background Art

[0002] Currently, the main methods and equipment for rapidly erecting cross-line bridges include truck-mounted crane systems and bridge-erecting machine systems. These existing methods and equipment require a long construction period, typically exceeding twenty days or even several months, resulting in detours and traffic congestion, increased energy consumption, noise, and environmental pollution. Furthermore, in addition to prolonged traffic interruption, existing methods also require that subsequent road-related construction of the main structure, connecting components, or ancillary equipment be carried out while traffic is open under the bridge. This poses significant safety risks during construction and is associated with high costs for protective equipment. Summary of the Invention

[0003] An object of the present invention is to solve at least the above problems and to provide at least the advantages which will be described hereinafter.

[0004] In order to achieve these objects and other advantages according to the present invention, a method for quickly erecting a bridge across a high embankment highway is provided, comprising: using multiple relay vehicle groups to relay and drive a beam body to move across the high embankment highway from one side of the high embankment highway, on the high embankment highway, and on the other side of the high embankment highway, and after the beam body has completed crossing the high embankment highway, driving the beam body to move longitudinally along the high embankment highway to a designed position; the relay vehicle group includes a mobile vehicle body and a vehicle-mounted support assembly, the height of the vehicle-mounted support assembly is adjustable, the mobile vehicle body is used to jack up the vehicle-mounted support assembly to connect it with the beam body, and drive the vehicle-mounted support assembly and the beam body to move; after the beam body moves to the designed position, each of the relay vehicle groups descends synchronously to make the beam body fall onto the completed bridge pier, thereby completing the bridge erection.

[0005] Preferably, before moving the beam, a transport path platform is constructed along the beam moving path, and each relay vehicle group moves on the transport path platform and the high embankment highway; the transport path platform includes: a roadbed side slope section platform arranged on the side slopes on both sides of the roadbed of the high embankment highway and a roadbed platform arranged on both sides of the high embankment highway; the roadbed side slope section platform and the roadbed platform are both flush with the road surface of the high embankment highway.

[0006] Preferably, the roadbed slope section platform is one of an earth and stone filling structure, a concrete pouring structure or a steel trestle structure.

[0036] like Figures 1 to 5 As shown, the present invention provides a method for quickly erecting a bridge across a high embankment highway, comprising: relaying a beam body 2 from one side of the high embankment highway 1, on the high embankment highway 1, and on the other side of the high embankment highway 1 through a plurality of relay vehicle groups 4, so that the beam body 2 moves across the high embankment highway 1, and after the beam body 2 crosses the high embankment highway 1, drives the beam body 2 to move longitudinally along the high embankment highway 1 to a designed position; the relay vehicle group 4 includes a mobile vehicle body and a vehicle-mounted support assembly 8, the height of the vehicle-mounted support assembly 8 is adjustable, the mobile vehicle body is used to jack up the vehicle-mounted support assembly 8 to connect it with the beam body 2, and drive the vehicle-mounted support assembly 8 and the beam body 2 to move and rotate; after the beam body 2 moves to the designed position, each of the relay vehicle groups 4 descends synchronously to make the beam body 2 fall onto the completed bridge pier 3, thereby completing the bridge erection.

[0037] Figure 1 and Figure 2The figure is a schematic diagram of the design position of a bridge over a high embankment highway, wherein the beam 2 spans the high embankment highway 1. In order to shorten the construction period of the bridge and minimize the impact of the bridge construction on the traffic flow of the high embankment highway, the present invention provides a method for quickly erecting a bridge over a high embankment highway. Figure 3 As shown, in this embodiment, 6 groups of relay vehicle groups 4 are arranged below the beam body 2, namely relay vehicle group 41, relay vehicle group 42, relay vehicle group 43, relay vehicle group 44, relay vehicle group 45 and relay vehicle group 46. In the relay vehicle group 4, the mobile vehicle body can be selected from the SPMT, transport and rack integrated machine, multi-kinetic transport vehicle, etc. in the existing technology, which integrates the hydraulic system, control system, and vehicle system of the traditional method to achieve jacking and shifting, and the single maximum stroke and rotation angle are configured according to engineering requirements; the vehicle-mounted support assembly 8 is composed of multiple standard segments connected in sequence in the vertical direction to facilitate adjustment of its height; the bottom of the vehicle-mounted support assembly 8 is fixedly connected to the jacking module of the mobile vehicle body, and is synchronously jacked or lowered with the mobile vehicle body. The multiple relay vehicle groups 4 are synchronously lifted, lowered, moved or rotated to drive the beam body 2 to rise, fall, move or rotate. Refer to Figure 3 In (a1), first, the relay vehicle group 41, the relay vehicle group 42, the relay vehicle group 43, the relay vehicle group 44, the relay vehicle group 45 and the relay vehicle group 46 move the beam body 2 to the position close to the high embankment road 1, and then Figure 3 As shown in (a2), a relay vehicle group 47 is set on the high embankment highway 1. After the beam body 2 continues to move forward to the vehicle-mounted support assembly 8 on the relay vehicle group 47 and is connected to the beam body 2, the relay vehicle group 42, the relay vehicle group 43, the relay vehicle group 44, the relay vehicle group 45 and the relay vehicle group 46 jointly drive the beam body 2 to move horizontally across the high embankment highway 1, and the relay vehicle group 41 is withdrawn at the same time; and as the beam body 2 further moves horizontally, as shown in FIG. Figure 3 As shown in (a3), the relay vehicle group 48 on the high embankment road 1 continues to join the relay vehicle group, and when the relay vehicle group 42 approaches the high embankment road 1, it is withdrawn; Figure 3 As shown in (a4), when the front end of the beam 2 crosses the high embankment road 1, the relay vehicle group 49 on the other side of the high embankment road takes over and joins in the movement of the beam 2; during this process, the relay vehicle groups 47 and 48 can alternately participate in the movement of the beam 2 on the high embankment road 1. The above relay movement process is repeated until the beam 2 completes its movement across the high embankment road 1; as shown in FIG. Figure 3As shown in (a5), as beam 2 continues to move laterally, relay vehicles 410 and 411 on the other side of high-embankment highway 1 sequentially join the relay vehicle group, and relay vehicles 43, 47, and 48 are withdrawn accordingly. Relay vehicles 49, 410, 411, 44, 45, and 46 then drive beam 2 longitudinally along high-embankment highway 1 to its designed position. Each relay vehicle group 4 is then simultaneously lowered, lowering beam 2 onto the completed pier 3, completing the bridge erection. Compared to existing methods of crane hoisting and bridge erection, this rapid bridge erection method for crossing high-embankment highways can shorten road construction time from over a week to within 6-12 hours, reducing energy consumption caused by vehicle detours and traffic congestion, being more energy-efficient and environmentally friendly, and significantly reducing safety risks during construction.

[0038] In another technical solution, referring to Figure 4 Considering that, for high-embankment highway 1, to support the beam 2 for smooth crossing, the relay vehicle groups 4 need to be equipped with higher onboard support assemblies 8. To further improve the stability of the beam 2 during transportation, a transportation path platform is constructed along the beam 2's movement path before the beam 2 is moved. Each relay vehicle group 4 moves on this transportation path platform and the high-embankment highway 1. The transportation path platform includes: a roadbed side slope platform 5 installed on the side slopes of the high-embankment highway's roadbed, and a roadbed platform 9 installed on both sides of the high-embankment highway. The roadbed side slope platform 5 and the roadbed platform 9 are both flush with the road surface of the high-embankment highway 1. The transportation path platform reduces the required height of the onboard support assembly 8, thereby improving the stability of the beam 2 during transportation.

[0039] In another technical solution, the roadbed slope section platform 5 is one of an earth and stone filling structure, a concrete pouring structure or a steel trestle structure.

[0040] In another technical solution, the roadbed platform 9 is one of an earth and stone filling structure, a concrete pouring structure or a steel trestle structure.

[0041] In another technical solution, the roadbed platform 9 is composed of multiple transfer vehicle groups 6, and the transfer vehicle groups 6 have the same structure as the relay vehicle groups 4; one transfer vehicle group 6 is correspondingly arranged under one relay vehicle group 4, and is detachably connected to the corresponding relay vehicle group 4 to form a group vehicle group 7.

[0042] like Figure 5As shown, the lower transport vehicle group 6 is used as a movable roadbed platform 9, which can further shorten the construction time compared to earth and stone filling structures, concrete pouring structures or steel trestle structures. During use, the transport vehicle group 6 and the relay vehicle group 4 can be connected using a support frame to increase the contact area between the two and ensure a stable connection. Columns can be set on both sides of the support frame. When the movement stops, the upper structure is lowered by the mobile body of the transport vehicle group 6, so that the columns can be supported on the ground, realizing the conversion of the support system and ensuring the stability of the support.

[0043] Further, refer to Figure 5 The bridge rapid erection method specifically comprises the following steps:

[0044] S1. After each carpooling group 7 is moved to a designated position below the beam 2, the transporting groups 6 below simultaneously lift the beam 2 to 5-10 cm above the designed elevation, and then move the beam 2 to the roadbed slope section platform 5 at the front end of the beam 2 near the high embankment highway 1 according to the transport path;

[0045] like Figure 5 As shown in (b1), the relay train set 41 and the transfer train set 61 are assembled and connected to form a group car set 71, the relay train set 42 and the transfer train set 62 are assembled and connected to form a group car set 72, the relay train set 43 and the transfer train set 63 are assembled and connected to form a group car set 73, and the relay train set 44 and the transfer train set 64 are assembled and connected to form a group car set 74.

[0046] S2, such as Figure 5 As shown in (b2), the traffic on the high embankment highway 1 is closed, and the beam body 2 is continued to move forward until the front-most group car group A71 is close to the roadbed slope section platform 5, and the connection between the relay car group A41 and the transfer car group A41 in the group car group A71 is released. The beam body 2 is continued to move forward by the relay car group A41 and the remaining group car groups 7 until the relay car group A41 moves from the transfer car group A61 to the roadbed slope section platform 5, and the transfer car group A61 is withdrawn at the same time;

[0047] like Figure 5 As shown in (b3) and (b4), S3, the relay vehicle group A41 and the remaining carpooling group 7 drive the beam body 2 to move across the high embankment highway 1. After the relay vehicle group A41 moves from the roadbed slope section platform 5 on the other side of the high embankment highway 1 to the transfer vehicle group B65 on the other side of the high embankment highway, the relay vehicle group A41 and the transfer vehicle group B65 are fixedly connected to form the carpooling group A′75, and continue to drive the beam body 2 to move laterally across the high embankment highway 1.

[0048] S4. During the movement of the beam 2 across the high embankment highway 1 in step S3, the remaining assembly vehicle groups 7 sequentially approach the roadbed slope platform 5 and separate and assemble the relay vehicle group and the transfer vehicle group according to steps S2 and S3;

[0049] like Figure 5 As shown in (b4), when the relay vehicle group A41 and the remaining vehicle groups 7 drive the beam body 2 to continue moving forward, when the vehicle group 72 moves close to the roadbed slope section platform 5, the connection between the relay vehicle group 42 and the transfer vehicle group 62 in the vehicle group 72 is released, allowing the relay vehicle group 42 to move from the transfer vehicle group 62 to the roadbed slope section platform 5, and the transfer vehicle group 62 is withdrawn; after the relay vehicle group 42 moves to the roadbed slope section platform 5, the relay vehicle group 42 is moved from the roadbed slope section platform 5 to the transfer vehicle group 66 on the other side of the high embankment highway 1, and reassembled into the vehicle group 76. The vehicle groups 73 and 74 also participate in the movement of the beam body 2 according to the above process.

[0050] S5, such as Figure 5 As shown in (b5), after the beam 2 has completed crossing the high embankment highway 1, the transfer vehicle group 6 under each group of carpooling groups 7 and the relay vehicle group 4 located on the roadbed slope section platform 5 are synchronously lifted, controlling the bottom surface of the beam 2 to be 5-10 cm above the top surface of the pier 3 pier top support, and driving the beam 2 to move longitudinally along the high embankment highway 1 to the designed position and then drop the beam, as shown in FIG. Figure 6 The bridge is erected in the direction indicated by the middle arrow, and all relay vehicle groups 4 and transfer vehicle groups 6 are withdrawn, opening the high embankment highway 1 to traffic. Expansion joints are then constructed, completing the rapid erection of the bridge over the high embankment highway. The bridge over the high embankment highway is then opened to traffic, and the temporary facilities are removed. In this embodiment, relay vehicle groups 43 and 44 do not need to be reassembled with their corresponding transfer vehicle groups. The beam 2 has already been moved into place, and the corresponding transfer vehicle groups can be directly withdrawn. In actual use, flexible selection and control can be achieved based on the length and design position of the beam 2.

[0051] In another technical solution, the following steps are further included before step S1:

[0052] S0-1, construction of roadbed slope section platform 5;

[0053] Construct pile foundation at the designed location, fill platform 5 of the roadbed slope section and harden the roadbed.

[0054] S0-2. Prefabricate piers and prefabricated supports for assembling main beams on site;

[0055] S0-3. Prefabricate the main beam on the prefabricated support; including concrete paving, guardrails, lighting facilities, anti-throwing nets, signs and markings, and embedded expansion joints;

[0056] S0-4. Install prefabricated piers at the designed locations;

[0057] S0-5. Complete the assembly of each carpooling group on the site.

[0058] In another technical solution, in step S1, the beam body 2 is divided into a beam section L1 that needs to cross the high embankment highway 1 and a beam section L2 that does not need to cross the high embankment highway 1 along its length direction, and a plurality of the said carpooling groups 7 are arranged below the said beam section L1, and a plurality of the said relay car groups 4 are arranged below the said beam section L2. Figure 5 As shown in (b5), a single-layer relay vehicle group 45 and a relay vehicle group 46 that are easier to control are set under the beam section 2 L2 to support the beam body 2. This can also reduce the investment in the transfer vehicle group 6 and further reduce costs.

[0059] In this technical solution, each carpooling group 7 below the beam section L1 must be separated when crossing the high embankment highway 1 and reassembled into a carpooling group on the other side of the high embankment highway 1 based on the designed position of the beam body 2. Therefore, further in step S4, while the beam section L1 is moving laterally across the high embankment highway 1, the remaining carpooling groups 7 sequentially approach the roadbed slope platform 5 and separate and reassemble the relay group and the transfer group according to steps S2 and S3.

[0060] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
