Description

Technical Field

[0001] This invention relates to the field of inland waterway bridge installation, and further to a method and system for installing inland waterway bridges using a combination of vehicle and vessel transportation. Background Technology

[0002] Currently, the main methods for erecting steel bridges or precast beams on inland waterways are cantilever assembly, rotation construction, and jacking construction.

[0003] The cantilever assembly method refers to a construction method in which working platforms are set up on both sides of the bridge piers, and beam segments are assembled in a balanced manner towards the mid-span until the bridge structure is closed. Its main disadvantage is that for prestressed concrete beams, the segment length is generally 2-5m. If the segments are too short, too many splices are detrimental to the structural stress and increase the construction period; if the segments are too long, they will be too heavy, requiring more sophisticated hoisting equipment and causing greater stress variations in the structure.

[0004] The rotation construction method involves prefabricating two halves of a bridge on either side of a river or at a suitable location using simple supports. Then, using the bridge structure itself as a rotating body, the two halves are rotated to their respective bridge positions and joined together to form the final bridge. The disadvantages include the complex and cumbersome manufacturing and adjustment processes for the ball joints, making closure control difficult; and the potential for structural cracks or even instability during the rotation process.

[0005] The incremental launching method refers to the construction method in which the bridge beam is assembled on the embankment behind the abutment and then longitudinally launched using a launching device, so that the beam is positioned by passing through temporary sliding devices on the tops of each pier. Its disadvantages include large span limitations, slow construction progress, and high costs.

[0006] Meanwhile, all of the above methods involve a long preparation period, which affects normal navigation. The construction process also generates a large amount of dust and noise, impacting the surrounding environment.

[0007] In conclusion, an installation method for inland river bridges should be designed to solve the above problems. Summary of the Invention

[0008] To address the aforementioned technical problems, the present invention aims to provide a method and system for installing inland waterway bridges using a combination of vehicle and ship transportation. The installation method can minimize the operation time and reduce the impact on waterway traffic. Furthermore, the equipment mobilization is quick and flexible, occupies little space, and requires a short preparation time.

[0009] To achieve the above objectives, the present invention provides a method for installing an inland waterway bridge using a vehicle-ship combination transport method, comprising the steps of: mounting the bases at both ends of the bridge to be installed onto a landside transport vehicle and a waterway transport vehicle, respectively; the landside transport vehicle travels on land; the waterway transport vehicle is located between the landside transport vehicle and the inland waterway; and the riverbanks on both sides are connected by a deck barge, allowing the waterway transport vehicle to travel along the deck barge to the other side of the waterway.

[0010] The landside transport vehicle and the airside transport vehicle are controlled to transport synchronously, so that the landside transport vehicle and the airside transport vehicle travel along a preset direction to the bridge installation position for bridge installation.

[0011] It should be noted that by using the landside transport vehicle and the airside transport vehicle to transport the bridge to be installed simultaneously, the cumbersome pre-installation preparation work is avoided. The transport vehicles shorten the construction and installation time. In addition, the construction and loading of the bridge to be installed are completed on one side of the riverbank, ensuring the strength and rigidity of the bridge to be installed.

[0012] In some embodiments, before the bridge end bases to be installed are respectively mounted on the landside transport vehicle and the airside transport vehicle, the process further includes:

[0013] Construct a construction platform to provide space for the construction or placement of the bridge to be installed.

[0014] And to provide a transportation platform for the landside transport vehicle and the airside transport vehicle so that the terrain is the same during the journey.

[0015] The construction of the platform is a preparatory step before bridge installation, providing a safety guarantee for subsequent transport vehicles.

[0016] In some embodiments, the construction platform includes a first-floor platform and a second-floor platform, wherein the horizontal position of the first-floor platform is lower than the horizontal position of the second-floor platform;

[0017] The single-layer platform is built on both sides of the riverbank to provide a transportation platform for the airside transport vehicle;

[0018] The second-level platform is built on one side of the riverbank and is used to construct the bridge to be installed with the second-level platform as a reference plane, as well as to provide a transportation platform for the landside transport vehicle.

[0019] In some embodiments, the two riverbanks are connected by a deck barge, allowing the transport vehicle to travel along the deck barge to the other side of the waterway. This includes: towing the deck barge to a preset position, fixing both ends of the deck barge to the two riverbanks, and making the upper surface of the deck barge substantially flush with the upper surface of the first-level platform.

[0020] It should be noted that, as can be seen from the above embodiments, the deck barge and the first-floor platform can form a transport channel for the navigation side transport vehicle to pass through. Here, the deck barge acts as a floating bridge, with sufficient buoyancy to support the navigation side transport vehicle to travel on it.

[0021] In some embodiments, the base of the bridge to be installed on the side near the inland waterway includes a support fixture, the bottom of which is placed on the first-level platform to support the bridge to be installed.

[0022] The supporting fixtures are designed and manufactured according to the mass and size of the bridge to be installed, so they can fit well with the bridge to be installed, ensuring the stability of the bridge to be installed.

[0023] In some embodiments, prior to the synchronized transport of the landside transport vehicle and the airside transport vehicle, the following steps are included:

[0024] The navigable side transport vehicle, which is close to the inland waterway, is controlled to enter the transport vehicle positioning position of the support fixture, the support fixture is lifted, and it is separated from the first-floor platform, so that the navigable side transport vehicle can travel to the deck barge via the ramp set between the first-floor platform and the deck barge.

[0025] It should be noted that the supporting fixtures prevent the bridge to be installed from shifting during the operation and travel of the airside transport vehicle, thus ensuring the safety and reliability of the construction.

[0026] In some embodiments, the method further includes: controlling the buoyancy of the deck barge by adjusting the ballast water in the deck barge compartment, so that when the shipside transport vehicle carrying the bridge to be installed travels onto the deck barge, the relative position of the deck barge is not easily shifted.

[0027] The ballast water in the deck barge plays a role in adjusting the load, making the stability of the aerial survey transport vehicle when carrying the bridge to be installed across the river more stable, and avoiding the situation where the aerial survey transport vehicle will veer off course due to uneven load.

[0028] In some embodiments, controlling the buoyancy of the deck barge by adjusting the ballast water in the deck barge compartment specifically includes:

[0029] Monitor the first distance between the deck barge surface and the waterline;

[0030] Ballast water is discharged or injected according to the first distance until both ends of the bridge to be installed are relatively horizontal and the bottom of the transport vehicle is horizontal above the water level.

[0031] It should be noted that since the ballast transport vehicle needs to carry the bridge to be installed on the deck barge, there is a high possibility that the overall weight will exceed the buoyancy during transportation, causing the ballast transport vehicle or the bridge to be installed to sink into the river, posing a great safety hazard. Therefore, by adjusting the ballast water, the relationship between gravity and buoyancy can be adjusted, making it less likely for the ballast transport vehicle to sink on the deck barge and less likely to cause construction risks.

[0032] Another aspect of the present invention also provides a vehicle-ship combined transportation inland waterway bridge installation system, comprising:

[0033] Landside transport vehicle, which travels on land;

[0034] A waterway transport vehicle, which is located between the landside transport vehicle and the inland waterway, and can travel along a deck barge connecting the two riverbanks to the other side of the waterway; a bridge to be installed, the two end bases of which are respectively mounted on the landside transport vehicle and the waterway transport vehicle.

[0035] The control terminal is used to control the landside transport vehicle and the airside transport vehicle to transport synchronously, so that the landside transport vehicle and the airside transport vehicle travel along a preset direction to the bridge installation position for bridge installation.

[0036] It should be noted that the installation system occupies little space and does not require a large number of large machines, thus avoiding the cumbersome steps of bringing in multiple pieces of equipment in the early stages. During transportation, controlling the land-side transport vehicle and the air-side transport vehicle to travel in a preset direction and speed can achieve a good transportation effect.

[0037] The number of landside transport vehicles and airside transport vehicles should be determined according to the needs to ensure sufficient power and support during transportation. In addition, the landside transport vehicles and airside transport vehicles respectively cross land and waterways, making the division of labor clearer and making the construction personnel and plans clearer.

[0038] In some implementations, it also includes:

[0039] A single-layer platform is set on both sides of the riverbank and is at a horizontal height above the water level. Supporting fixtures are installed on the single-layer platform.

[0040] The second-level platform is set on the first-level platform near the landside transport vehicle, and its surface is basically flush with the supporting fixture, which can be used to place the bridge to be installed.

[0041] The construction platform described above can be used to place the bridge to be installed and can also be used for transport vehicles to pass through. Due to the construction platform, the transport vehicles will be more stable during the journey and are less likely to have accidents during the transport of the bridge to be installed.

[0042] Compared with the prior art, the vehicle-ship combined transportation inland waterway bridge installation method and system provided by the present invention has the following beneficial effects:

[0043] 1. The present invention provides a vehicle-ship combined transportation method and system for installing inland waterway bridges, which utilizes a transport vehicle and a deck barge to achieve the effect of synchronously advancing both ends of the bridge to be installed towards the installation position. It does not require a lot of preparation time in the early stage, saves costs and is highly practical.

[0044] 2. The present invention provides a method and system for installing an inland waterway bridge that combines vehicle and vessel transportation, wherein the deck barge is used as a floating bridge, which can provide a transportation platform and adjust its buoyancy in a timely manner to make the transportation process safer.

[0045] 3. The present invention provides a vehicle-ship combined transportation method and system for installing inland waterway bridges, which uses a self-propelled modular transport vehicle for transportation and has good load-bearing capacity to support bridges of different sizes to be installed.

Obviously, the drawings described below are merely some embodiments of the present invention.

[0062] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0063] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0064] In one embodiment, refer to the appendix to the specification. Figure 1The present invention describes a method for installing inland waterway bridges using a combination of vehicle and ship transportation. This method can minimize the operation time and reduce the impact on waterway traffic. On the other hand, it is also intended to allow for quick and flexible equipment mobilization, small space occupation, and short preparation time.

[0065] Reference manual attached Figure 1 The present invention provides a method for installing an inland waterway bridge using a combination of vehicle and ship transportation, comprising the following steps:

[0066] S1. The foundations at both ends of the bridge to be installed are respectively mounted on the landside transport vehicle and the waterway transport vehicle. The landside transport vehicle travels on land, while the waterway transport vehicle is located between the landside transport vehicle and the inland waterway. The two riverbanks are connected by a deck barge, allowing the waterway transport vehicle to travel along the deck barge to the other side of the waterway.

[0067] S2. Control the landside transport vehicle and the airside transport vehicle to transport synchronously, so that the landside transport vehicle and the airside transport vehicle travel along the preset direction to the bridge installation position and carry out bridge installation.

[0068] It should be noted that the landside transport vehicle and the airside transport vehicle used in the embodiments of the present invention are both self-propelled modular transporters (SPMTs). Different types of transport vehicles can also be used depending on the actual situation.

[0069] The simultaneous transport of the bridge to be installed using both landside and airside transport vehicles avoids cumbersome pre-installation preparations and shortens the construction and installation time. Furthermore, the construction and loading of the bridge to be installed are all completed on one side of the riverbank, ensuring the strength and rigidity of the bridge.

[0070] Specifically, before transportation begins, both the airside transport vehicle and the landside transport vehicle are on one side of the river. The operators can then load the bridge to be installed onto the airside and landside transport vehicles. During transportation, the airside transport vehicle will travel to the deck barge and then to the other side of the river. At this point, the airside and landside transport vehicles will be on opposite sides of the river. Subsequently, the construction personnel will control the airside and landside transport vehicles to simultaneously transport the bridge to be installed until it reaches the designated installation position, and then the bridge installation and fixing work will be carried out.

[0071] In one embodiment, refer to the appendix to the specification. Figure 2 Before the bridge bases at both ends to be installed in step S1 are mounted on the landside transport vehicle and the airside transport vehicle respectively, the following steps are also included:

[0072] S01. Construct a construction platform to provide a site for the construction or placement of bridges to be installed, and to provide a transportation platform for landside and airside transport vehicles.

[0073] The construction of the platform is a preparatory step before bridge installation. Warning signs should be placed around the construction area to ensure the safety of people in the vicinity. The construction of the platform should be tailored to specific needs, taking into account factors such as the quality and size of the bridge to be installed, and the vibrations generated when the transport vehicle carries the bridge. At the same time, the platform should be built as flat as possible to ensure that the transport vehicle travels on the same terrain and that the bridge to be installed is not prone to shifting.

[0074] In one embodiment, refer to the appendix to the specification. Figure 8 The construction platform includes a first-level platform 51 and a second-level platform 52. The horizontal position of the first-level platform 51 is lower than that of the second-level platform 52. The first-level platform 51 is built on both sides of the riverbank to provide a transportation platform for the airside transport vehicle. The second-level platform 52 is built on one side of the riverbank to build the bridge to be installed with the second-level platform 52 as the reference plane, and to provide a transportation platform for the landside transport vehicle.

[0075] In one embodiment, please refer to the appendix to the specification. Figure 5 and Figure 6 The foundation of the bridge to be installed on the side near the inland waterway includes a support fixture 4. The bottom of the support fixture is placed on a first-level platform 51 to support the bridge to be installed.

[0076] The supporting fixtures are designed and manufactured according to the quality and size of the bridge to be installed, so they can work well with the bridge and ensure its stability.

[0077] It should be noted that, as shown in the above embodiments, both the first-level platform 51 and the second-level platform 52 play a certain supporting role. The distance difference between the horizontal positions of the first-level platform 51 and the second-level platform 52 is basically equal to the height of the support fixture 4, which makes the support fixture 4 more stable when supporting the bridge base 11 to be installed, providing a safety guarantee for the movement of the air-side transport vehicle. In addition, during construction and transportation, the horizontal position offset of the air-side transport vehicle and the land-side transport vehicle should be minimized. Without the construction platform, the unevenness and slope of the ground itself may cause the transport vehicle to deviate from the planned driving state, thereby affecting the subsequent bridge installation work.

[0078] In another embodiment, refer to the appendix to the specification. Figure 3 Before the two riverbanks are connected by a deck barge in step S1 of the above embodiment, allowing the transport vehicle to travel along the deck barge to the other side of the channel, the steps include:

[0079] S02. Tow the deck barge to the preset position and fix both ends of the deck barge to the riverbanks on both sides, and make the upper surface of the deck barge basically flush with the upper surface of the first-level platform. The first-level platform is built on both sides of the riverbank to provide a transportation platform for the shipside transport vehicle.

[0080] It should be noted that, as can be seen from the above embodiments, the deck barge and the first-floor platform can form a transport channel for the navigation side transport vehicle to pass through. Here, the deck barge acts as a floating bridge, with sufficient buoyancy to support the navigation side transport vehicle to travel on it.

[0081] Specifically, construction workers can operate tugboats to tow the deck barge to the preset position. In addition, referring to the attached diagram in the instruction manual, construction workers can use anchor cables and other fixing structures to secure the deck barge to prevent it from shaking. Here, it is important to ensure that the deck barge and the bridge installation position are on the same straight line as much as possible to minimize offset and avoid the need for multiple adjustments to the bridge position during subsequent bridge installation.

[0082] It should be noted that the deck barge is long enough, with both ends close to the riverbanks on both sides of the inland river, which makes the side transport vehicle safer during the journey and avoids long preparation time. The side transport vehicle can quickly cross to the other side of the river using the deck barge.

[0083] In one embodiment, before controlling the synchronized transport of the landside transport vehicle and the airside transport vehicle in step S2, the following steps are included:

[0084] S03. Control the waterway side transport vehicle close to the inland waterway to enter the customized transport vehicle position of the support equipment, lift the support equipment, and separate it from the first-floor platform so that the waterway side transport vehicle can travel to the deck barge through the ramp set between the first-floor platform and the deck barge.

[0085] It should be noted that the support fixture is designed and customized based on the quality and size of the bridge to be installed and the size of the aerial survey transport vehicle, combined with the construction environment and external factors. Therefore, the support fixture ensures that the bridge to be installed, which is supported by the aerial survey transport vehicle, is less likely to shift during operation and travel, and the safety and reliability during construction are also well guaranteed. In addition, the customized position of the transport vehicle is generally set on the lower side of the support fixture, that is, the side closer to the first-level platform. After the aerial survey transport vehicle drives into the customized position, since the bottom of the support fixture is placed on the first-level platform, the lifting device on the aerial survey transport vehicle is used to lift the support fixture, so that its bottom is away from the first-level platform, and then the aerial survey transport vehicle can load the bridge to be installed and drive to the installation position.

[0086] In one embodiment, step S2, which involves controlling the landside transport vehicle and the airside transport vehicle to transport synchronously, directing them to travel in a preset direction to the bridge installation location, includes the following steps:

[0087] S21. By adjusting the ballast water in the deck barge compartment, the buoyancy of the deck barge is controlled, so that when the shipside transport vehicle carrying the bridge to be installed travels onto the deck barge, the relative position of the deck barge is not easily shifted.

[0088] The ballast water in the deck barge plays a role in adjusting the load, making the stability of the aerial survey transport vehicle when carrying the bridge to be installed across the river more stable, and avoiding the situation where the aerial survey transport vehicle will veer off course due to uneven load.

[0089] Specifically, during the roll-on / roll-off loading of the bridge onto the ship, the load gradually transfers to the deck barge, at which point the load should be leveled and adjusted. During the roll-off / roll-off unloading of the bridge onto the ship, the load gradually transfers from the deck barge to the other platform, at which point the ballast should be leveled and adjusted. At the same time, it is also necessary to closely monitor the tide conditions and adjust the ballast water in the deck barge's hold in a timely manner according to the tide conditions.

[0090] In one embodiment, based on the above embodiments, step S21, controlling the buoyancy of the deck barge by adjusting the ballast water in the deck barge compartment, specifically includes:

[0091] S211, Monitor the first distance between the surface of the deck barge and the waterline.

[0092] S212. Discharge or inject ballast water according to the first distance until the two ends of the bridge to be installed are relatively horizontal and the bottom of the transport vehicle on the side is above the water level.

[0093] It should be noted that, since the airside transport vehicle needs to carry the bridge to be installed on the deck barge, there is a high possibility that the overall weight will exceed the buoyancy during transportation, causing the airside transport vehicle or the bridge to be installed to sink into the river, posing a great safety hazard. Therefore, by adjusting the ballast water, the airside transport vehicle traveling on the deck barge is less likely to sink and cause transportation risks.

[0094] In one embodiment, refer to the appendix to the specification. Figure 6 According to another aspect of the present invention, the present invention further provides a vehicle-ship combined transport inland waterway bridge installation system, including a landside transport vehicle 21, a waterway transport vehicle 22, a bridge to be installed 1, and a control terminal. The landside transport vehicle 21 travels on land; the waterway transport vehicle 22 travels between the landside transport vehicle 21 and the inland waterway, and the waterway transport vehicle 22 can travel along the deck barge 3 connecting the two river banks to the other side of the waterway; the two end bases of the bridge to be installed 1 are respectively mounted on the landside transport vehicle 21 and the waterway transport vehicle 22; the control terminal is used to control the landside transport vehicle 21 and the waterway transport vehicle 22 to transport synchronously, so that the landside transport vehicle 21 and the waterway transport vehicle 22 travel in a preset direction to the bridge installation position for bridge installation.

[0095] It should be noted that the installation system occupies little space and does not require a large number of large machines, thus avoiding the cumbersome steps of bringing in multiple pieces of equipment in the early stage and avoiding the generation of a lot of noise. The deck barge 3 has sufficient buoyancy to support the side transport vehicle 22 to transport the bridge 1 to be installed across the inland waterway. During the transportation process, the transport vehicle is controlled to travel in the preset direction and speed, which can achieve a good transportation effect.

[0096] The number and distribution of transport vehicles are determined according to requirements to ensure sufficient power and support during transportation. Landside transport vehicle 21 and airside transport vehicle 22 traverse land and waterways respectively, making the division of labor among construction personnel clearer and the plan more precise. The transport vehicles are equipped with hydraulic lifting systems, which can simultaneously control the lifting of the bridge to be installed during transportation, achieving a good effect of adjusting its relative height. In addition, the transport vehicles are equipped with electronic overspeed safety protection devices to prevent the hydraulic motors from overspeeding or disengaging from other hydraulic motors when the vehicle is running on slippery surfaces or when the drive suspension loses traction. This device can also serve as an independent locking device to prevent movement of a single drive wheel, ensuring that the airside transport vehicle 22 does not slip when passing through connecting modules, thus improving safety.

[0097] Based on the above embodiments, please refer to the appendix to the specification. Figure 4 and Figure 8 The installation system also includes a construction platform, which consists of a first-floor platform and a second-floor platform.

[0098] The first-level platform 51 is set on both sides of the riverbank and is higher than the water level. The first-level platform 51 is equipped with support fixtures 4. The second-level platform 52 is set on the first-level platform near the side of the bridge 1 to be installed and its surface is basically flush with the support fixtures 4. It can be used to place the bridge 1 to be installed.

[0099] It should be noted that the instruction manual is attached. Figure 5 The construction platform is used to place the bridge to be installed 1 and to allow transport vehicles to pass. Due to the construction platform, the transport vehicles will be more stable during the journey and less likely to have accidents during the transport of the bridge to be installed.

[0100] Reference manual attached Figure 6 One of the platforms 51 is basically flush with the upper surface of the deck barge 3, which makes it easier for the shipside transport vehicle 22 to drive onto the deck barge 3. There will not be a large height difference between the two, thus avoiding the overall transportation instability caused by the large difference in the horizontal position of the two ends of the bridge to be installed 1.

[0101] In one embodiment, refer to the appendix to the specification. Figure 7 and Figure 10A ramp 6 is installed between the deck barge 3 and the riverbank. The length of the deck barge 3 is approximately equal to the width of the inland river and both ends are fixed by anchor cables, so that the side transport vehicle 22 can travel onto the deck barge via the ramp.

[0102] It should be noted that the deck barge 3 is towed into the inland waterway using tugboats or other tools. The deck barge 3 is long enough that both ends are close to the riverbanks on both sides of the inland waterway. A ramp 6 is set between the first-level platform and the deck barge 3. The ramp 6 and the deck barge 3 are properly secured to ensure the safety of the side transport vehicle 22 during its journey. This also avoids the long preparation time that would have been caused by building a floating transport platform that crosses the inland waterway. The side transport vehicle 22 can quickly board the deck barge using the ramp 6 to shorten the time required to reach the other side of the riverbank.

[0103] In one embodiment, the method for installing an inland waterway bridge using a vehicle-ship combined transport system provided by the present invention includes the following steps:

[0104] S31, Reference Instruction Appendix Figure 4 Construction platforms were built on both sides of the riverbank, and supporting equipment was placed on one side of the construction platform.

[0105] S32, Reference Instruction Appendix Figure 5 The bridge to be installed is constructed and / or placed on the side where the supporting fixture is provided, and the base of one side of the bridge to be installed is placed on the supporting fixture.

[0106] S33, Reference Manual Appendix Figure 6 The other side of the bridge to be installed is supported by the landside transport vehicle; the airside transport vehicle enters the transport vehicle carrying position of the supporting fixture and lifts the supporting fixture off the ground; the landside transport vehicle and the airside transport vehicle simultaneously carry the bridge to be installed and travel to the installation position via the deck barge (the deck barge is fixed to both sides of the riverbank by towing tools such as tugboats in any step of S31-S33).

[0107] S34, Reference Manual Appendix Figure 7 The landside transport vehicle and the airside transport vehicle simultaneously carry the bridge to be installed to the installation position for bridge installation.

[0108] S35, Reference Instruction Appendix Figure 8 The side transport vehicle carries the supporting equipment and drives onto the deck barge, and appropriate securing measures are taken.

[0109] S36, Reference Instruction Appendix Figure 9 The deck barge was towed away from the river by tugboat, and the landside transport vehicle left the site, completing the installation work.

[0110] It should be noted that in step S35, the transport vehicle carrying the support equipment drives onto the deck barge, and in step S36, the deck barge is towed away from the river by a tugboat. The decision on whether the transport vehicle can leave via the surrounding roads can be made based on the on-site construction and surrounding road conditions, which is more convenient and faster. If there are no roads available for travel nearby, the steps in this embodiment can be used for evacuation.

[0111] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
