Description

TECHNICAL FIELD

[0001] The present application relates to the field of inland river bridge installation, and further relates to an inland river bridge installation method and system. BACKGROUND

[0002] At present, the erection of steel bridges or precast beams on the current inland waterway mainly adopts cantilever assembly method, swivel construction method and incremental launching construction method.

[0003] The cantilever assembly method refers to a construction method in which working platforms are arranged on both sides of the bridge pier, the beam segments are balanced and assembled in sections towards the midspan in cantilever, and the bridge span structure is closed until the construction period is lengthened.

[0004] The swivel construction method is to use the ground to form a simple support at both banks of the river or at a suitable position, and to precast a half bridge, and then to use some machines and equipment to swivel the two half bridges to the bridge axis position to close the bridge. The disadvantages are that the ball hinge processing and grinding are complex, the closure control is difficult, and structural cracks or even instability may occur during the swivel process.

[0005] The incremental launching construction method refers to a construction method in which the beam body is assembled on the embankment behind the abutment, and is longitudinally pushed by a pushing device so that the beam body slides through the temporary sliding device on each pier and is positioned. The disadvantages are that the span limit is large, the construction progress is slow, and the cost is high.

[0006] At the same time, the above methods have a long preparation period, which affects normal navigation. A large amount of dust and noise is generated during construction, which affects the surrounding environment.

[0007] In summary, an inland river bridge installation method should be designed to solve the above problems. SUMMARY

[0008] In view of the above technical problems, the purpose of the present application is to provide an inland river bridge installation method and system, which can shorten the operation time as much as possible and reduce the influence on the waterway traffic. On the other hand, the equipment is mobilized quickly and flexibly, occupies small space, and has short preparation time.

[0009] In order to achieve the above purpose, the present application provides an inland river bridge installation method, which comprises the following steps:

[0010] loading the bridge to be installed by at least two land-side transport vehicles and transporting it to a first predetermined position,

[0011] A deck barge is arranged between the two riverbanks, and a navigation-side transport vehicle is arranged on the deck barge and can move along the deck barge;

[0012] The end of the bridge to be installed close to the riverbank is detached from the land-side transport vehicle on the side close to the riverbank and is fixedly installed on the navigation-side transport vehicle;

[0013] The land-side transport vehicle and the navigation-side transport vehicle are controlled to be synchronously transported along the extension direction of the deck barge until the bridge to be installed spans the river to a second preset position;

[0014] The bridge to be installed is detached from the land-side transport vehicle and the navigation-side transport vehicle and is installed.

[0015] It should be noted that the land-side transport vehicle synchronously transports the bridge to be installed to the riverbank first, and then the bridge to be installed is transferred from the land-side transport vehicle close to the riverbank to the navigation-side transport vehicle, so that the remaining land-side transport vehicle and navigation-side transport vehicle travel together and transport the bridge to be installed to the other side of the riverbank; in this process, the navigation-side transport vehicle is always active on the deck barge, and there is no need to build a platform on the riverbank to transfer the transport vehicle from land to river, which increases the safety.

[0016] In some embodiments, the loading of the bridge to be installed by the at least two land-side transport vehicles to the first preset position specifically comprises:

[0017] The position of the bridge to be installed is adjusted so that the bridge to be installed is erected on each land-side transport vehicle;

[0018] The land-side transport vehicles are controlled to be synchronously transported to the first preset position.

[0019] In some embodiments, the adjustment of the position of the bridge to be installed so that the bridge to be installed is erected on each land-side transport vehicle comprises:

[0020] According to the structure and size of the bridge to be installed and the number of the land-side transport vehicles, the transport vehicle carrying position of the bottom of the bridge to be installed is determined;

[0021] According to the transport vehicle carrying position, the land-side transport vehicles are driven to the bottom of the bridge to be installed for fixed installation.

[0022] Wherein, the corresponding transport vehicle carrying position is set according to the specific number of land-side transport vehicles and the weight of the bridge to be installed and other factors to ensure the stability of the bridge to be installed when it is fixedly installed on the transport vehicle, and a preliminary design is made for the subsequent navigation-side transport vehicle to replace the land-side transport vehicle close to the riverbank for transportation.

[0023] In some embodiments, after controlling each of the landside transport vehicles to be simultaneously transported to the first preset position, the process includes:

[0024] Simultaneously, the pressure on each of the landside transport vehicles is released and they descend, allowing the riverbank side of the bridge to be installed to be transferred to the airside transport vehicle.

[0025] Adjusting the ballast water inside the deck barge is used to change the buoyancy of the deck barge when the shipside transport vehicle passes by, so that the two ends of the bridge to be installed are relatively horizontal.

[0026] In some implementations, the simultaneous depressurization and descent of each of the landside transport vehicles specifically includes:

[0027] Control each of the landside transport vehicles to lift synchronously so that the side of the bridge to be installed near the riverbank is above the airside transport vehicle;

[0028] Detect the vertical distance between the bridge to be installed and the airside transport vehicle;

[0029] The depressurization amount of each landside transport vehicle is set according to the detection distance;

[0030] Control each of the aforementioned landside transport vehicles to depressurize and descend accordingly.

[0031] It should be noted that the depressurization and retraction of the landside transport vehicle allows the side of the bridge to be installed, closer to the riverbank, to land on the airside transport vehicle, thereby enabling the airside transport vehicle and the landside transport vehicle to simultaneously transport the bridge to be installed.

[0032] In some embodiments, the pressure relief includes a first pressure relief of the landside transport vehicle near the riverbank and a second pressure relief of the landside transport vehicle carrying the bridge base away from the riverbank.

[0033] The aforementioned setting the depressurization amount for each landside transport vehicle based on the detection distance; controlling each landside transport vehicle to depressurize and descend, specifically includes:

[0034] By controlling the loading of the first pressure relief amount to reduce the height of the landside transport vehicle near the riverbank, the landside transport vehicle and the bridge to be installed have no contact surface, and the bridge to be installed is transferred to the riverside transport vehicle.

[0035] By synchronously controlling the loading of the second pressure relief amount, the positions of both ends of the bridge to be installed are relatively horizontal when the first pressure relief amount is loaded and after the first pressure relief amount is completed.

[0036] Wherein, the first pressure relief amount is greater than the second pressure relief amount. The landside transport vehicle closer to the riverbank needs to place one end of the bridge to be installed on the airside transport vehicle after the pressure is released and withdraw from the construction site as needed. Meanwhile, the landside transport vehicle farther from the riverbank needs to play a supporting role and adjust the balance of the two ends of the bridge to be installed during this process, so as to achieve the effect of safely and stably transporting the bridge to be installed simultaneously through the landside transport vehicle and the airside transport vehicle.

[0037] In some embodiments, adjusting the ballast water inside the deck barge to change the buoyancy of the deck barge when the shipside transport vehicle passes by the deck barge specifically includes:

[0038] Monitor the first distance between the deck barge surface and the waterline;

[0039] Ballast water is discharged or injected based on the first distance monitored until the two ends of the bridge to be installed are relatively horizontal and the bottom of the transport vehicle is above the water level.

[0040] It should be noted that since the airside transport vehicle needs to carry the bridge to be installed on the deck barge, the overall weight may be greater than the buoyancy during transportation, causing the wheels and other parts of the airside transport vehicle to sink into the river, posing a great safety hazard. Therefore, by adjusting the ballast water, the relationship between gravity and buoyancy is adjusted, so that the airside transport vehicle traveling on the deck barge is less likely to sink and cause transportation risks.

[0041] Another aspect of the present invention also provides an inland waterway bridge installation system, comprising:

[0042] A landside transport vehicle that travels on land;

[0043] A side-ship transport vehicle that travels on a deck barge, the non-powered deck barge connecting the two sides of the riverbank;

[0044] The bridge to be installed, the base of which can be mounted on the landside transport vehicle and the airside transport vehicle respectively;

[0045] The control terminal is used to control each of the landside transport vehicles to synchronously transport the bridge to be installed to the first preset position;

[0046] And used to control the landside transport vehicle near the riverbank to transfer one end of the bridge to be installed to the airside transport vehicle;

[0047] And to control the landside transport vehicle and the airside transport vehicle to synchronously transport the bridge to be installed to the second preset position along the direction of the deck barge.

[0048] It should be noted that after the landside transport vehicle travels to the first preset position, the base of one side of the bridge to be installed is close to or above the airside transport vehicle. After the base is transferred from the corresponding landside transport vehicle to the airside transport vehicle, the remaining landside transport vehicles and airside transport vehicles will continue to transport synchronously so that the base of one side of the bridge to be installed can cross the river to the installation position.

[0049] In some embodiments, both the landside transport vehicle and the airside transport vehicle are equipped with lifting devices to adjust the relative position of the bridge to be installed.

[0050] In some embodiments, corresponding transport support fixtures are respectively set between the bridge to be installed and the landside transport vehicle, and between the bridge to be installed and the airside transport vehicle. The transport support fixtures are provided with transport vehicle entry positions to support the corresponding transport vehicles.

[0051] The transport support equipment is designed and manufactured based on factors such as the size and quality of the bridge to be installed and the on-site construction environment, so it has high reliability and plays an excellent supporting role.

[0053] Beneficial effects:

[0054] 1. The inland river bridge installation method and system provided by the present invention utilizes landside transport vehicles and waterside transport vehicles to transport the bridge to be installed simultaneously, avoiding the problems of long preparation time and slow construction progress caused by using a large number of large equipment for construction.

[0055] 2. The inland river bridge installation method and system provided by the present invention allows the bridge to be installed to be constructed on one side of the riverbank before being transported and installed across the river, thus avoiding structural cracks or instability that would occur during the process of rotating two half-bridges to the bridge axis position and then closing them together.

The inland river bridge installation method and system provided by the present invention will not generate very large noise during the process of the landside transport vehicle and the waterway transport vehicle carrying the bridge to be installed, and will have little impact on the surrounding environment.

[0070] 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.

[0071] 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.

[0072] In one embodiment, refer to the appendix to the specification. Figure 1 The present invention describes an inland waterway bridge installation method that can minimize operation time and reduce the impact on waterway traffic; on the other hand, it aims to enable quick and flexible equipment mobilization, occupy little space, and have a short preparation time.

[0073] Reference manual attached Figure 1 The present invention provides a method for installing an inland waterway bridge, comprising the following steps:

[0074] S1. The bridge to be installed is loaded onto at least two landside transport vehicles and transported to the first preset position. A deck barge is set up between the two riverbanks, and a landside transport vehicle that can move along the deck barge is installed on the deck barge.

[0075] S2. Remove the end of the bridge to be installed from the landside transport vehicle on the side closest to the riverbank and fix it on the airside transport vehicle.

[0076] S3. Control the landside transport vehicle and the shipside transport vehicle to transport synchronously along the extension direction of the deck barge until the bridge to be installed crosses the river to the second preset position.

[0077] S4. The bridge to be installed is disassembled from the landside transport vehicle and the airside transport vehicle and then installed.

[0078] It should be noted that the aforementioned landside transport vehicles will first transport the bridge to be installed to the riverbank, and then transfer the bridge to be installed from the landside transport vehicle near the riverbank to the airside transport vehicle, allowing the remaining landside transport vehicles and airside transport vehicles to travel together and transport the bridge to be installed to the other side of the riverbank. During this process, the airside transport vehicles will remain on the deck barge, eliminating the need to build a platform on the riverbank to transfer the transport vehicles from land to the river, thus increasing safety.

[0079] In addition, the first preset position mentioned should be set near the riverbank to ensure that there is no large positional difference during the transfer of the bridge to be installed from the landside transport vehicle to the airside transport vehicle. The second preset position should also be set near the bridge installation position. After reaching the second preset position, the bridge position can be adjusted by using lifting equipment or the lifting device of the transport vehicle, and installation can be carried out quickly.

[0080] It should also be noted that the order of step S1, which involves loading the bridge to be installed onto at least two landside transport vehicles and transporting it to the first preset location, and step S2, which involves setting up deck barges between the two riverbanks, can be changed according to the specific construction situation. There is no sequential relationship between the two steps.

[0081] In one embodiment, refer to the appendix to the specification. Figure 2 Step S1 involves transporting the bridge to be installed to the first preset location using at least two landside transport vehicles, specifically including:

[0082] S10. Adjust the position of the bridge to be installed so that it is mounted on each landside transport vehicle.

[0083] S11. Control each landside transport vehicle to transport to the first preset position simultaneously.

[0084] In one embodiment, based on the above embodiments, step S10, adjusting the position of the bridge to be installed so that the bridge to be installed is erected on each landside transport vehicle, includes:

[0085] Based on the structure and dimensions of the bridge to be installed, as well as the number of landside transport vehicles, determine the transport vehicle location at the bottom of the bridge to be installed; based on the transport vehicle location, have the landside transport vehicles drive to the bottom of the bridge to be installed for fixed installation.

[0086] According to the above embodiments, the corresponding transport vehicle positions are set according to factors such as the specific number of landside transport vehicles and the weight of the bridge to be installed, so as to ensure the stability of the bridge to be installed when it is fixedly installed on the transport vehicle. Furthermore, a pre-design was made to allow the airside transport vehicle to take over the landside transport vehicle closer to the riverbank for subsequent transport.

[0087] Among them, there are at least two landside transport vehicles to ensure that after the landside transport vehicle on the side closest to the riverbank is depressurized and returns to its original position, the bridge to be installed can remain balanced and will not shift on one side. The bridge can also be transported to the river crossing simultaneously by the landside transport vehicle and the riverside transport vehicle.

[0088] In one embodiment, refer to the appendix to the specification. Figure 2 After the landside transport vehicle loads the bridge to be installed and transports it to the first preset position in step S11, the following steps are included:

[0089] S12. Simultaneously control the depressurization and descent of each landside transport vehicle, so that the side of the bridge to be installed that is closer to the riverbank can be transferred to the airside transport vehicle.

[0090] In step S12, the depressurization and descent of each landside transport vehicle are controlled simultaneously. Firstly, when the landside transport vehicle depressurizes and descents, one end of the bridge to be installed can fall onto the landside transport vehicle. Secondly, some landside transport vehicles can leave the construction site after depressurization and descent to complete other installation work as needed, thereby improving the utilization rate of resources.

[0091] S21. Adjust the ballast water inside the deck barge to change the buoyancy of the deck barge when the shipside transport vehicle passes by.

[0092] The adjustment of the ballast water inside the deck barge in step S21 above, which is used to change the buoyancy of the deck barge when the shipside transport vehicle passes by, can play a role in adjusting the buoyancy and balance of the deck barge when the bridge to be installed is transferred from the landside transport vehicle to the shipside transport vehicle. It should be adjusted in real time according to the specific river conditions and on-site construction environment during the shipside transport vehicle's journey, which improves flexibility and reliability.

[0093] In another embodiment, step S12 involves simultaneously depressurizing and lowering each landside transport vehicle so that the side of the bridge to be installed closer to the riverbank can be transferred to the airside transport vehicle. Specific steps include:

[0094] S121. Control each landside transport vehicle to lift synchronously so that the side of the bridge to be installed that is close to the riverbank is above the airside transport vehicle.

[0095] S122. Detect the vertical distance between the bridge to be installed and the airside transport vehicle.

[0096] S123. Set the pressure relief amount for each landside transport vehicle based on the detection distance.

[0097] S124. Control each landside transport vehicle to depressurize and drop accordingly, so that one end of the bridge to be installed is transferred to the airside transport vehicle.

[0098] It should be noted that after each landside transport vehicle completes depressurization and returns to its original position, the airside transport vehicle and the landside transport vehicle can simultaneously transport the bridge to be installed during subsequent construction. Moreover, the depressurization amount is set according to the distance between the bridge to be installed and the airside transport vehicle, which is more objective and targeted, and makes it less likely that the bridge will be damaged or cracked due to collisions during the process of moving the bridge to be installed to the airside transport vehicle.

[0099] In one embodiment, the pressure relief amount includes a first pressure relief amount for the landside transport vehicle located near the riverbank and a second pressure relief amount for the landside transport vehicle carrying the bridge base located away from the riverbank, with the pressure relief amount for each landside transport vehicle set according to the detection distance as mentioned above.

[0100] Step S124, which involves controlling each landside transport vehicle to depressurize and descend accordingly, so that one end of the bridge to be installed is transferred to the airside transport vehicle, specifically includes:

[0101] S01. By controlling the first pressure relief amount, the height of the landside transport vehicle near the riverbank is reduced so that there is no contact between the landside transport vehicle and the bridge to be installed, and the bridge to be installed is transferred to the riverside transport vehicle.

[0102] S02. By synchronously controlling the loading of the second pressure relief amount, the positions of both ends of the bridge to be installed are relatively horizontal when the first pressure relief amount is loaded and after the first pressure relief amount is loaded.

[0103] In this process, the first pressure relief is greater than the second pressure relief. The landside transport vehicle, which is closer to the riverbank, needs to place one end of the bridge to be installed on the airside transport vehicle after the pressure is released. At this time, the landside transport vehicle, which is closer to the riverbank, does not play a supporting role and can be removed from the construction site as needed. Meanwhile, the landside transport vehicle, which is farther from the riverbank, needs to play a supporting role and adjust the balance of the two ends of the bridge to be installed by controlling the second pressure relief, so as to achieve the effect of safely and stably transporting the bridge to be installed simultaneously through the landside transport vehicle and the airside transport vehicle.

[0104] In one embodiment, adjusting the ballast water inside the deck barge in step S21 to change the buoyancy of the deck barge when the shipside transport vehicle passes by the deck barge specifically includes:

[0105] S210, Monitor the first distance between the surface of the deck barge and the waterline.

[0106] S211. Based on the first distance monitored, drain or inject ballast water until the positions of both ends of the bridge to be installed are relatively horizontal and the bottom of the transport vehicle on the side of the waterway is higher than the water level.

[0107] It should be noted that since the airside transport vehicle needs to carry the bridge to be installed on the deck barge, the overall weight may be too large during transportation. If the buoyancy provided by the deck barge is insufficient, the wheels and other parts of the airside transport vehicle may sink into the river, causing a great safety hazard. Therefore, by adjusting the ballast water, the relationship between gravity and buoyancy is adjusted so that the airside transport vehicle traveling on the deck barge is less likely to sink and cause transportation risks.

[0108] In addition, whether draining or injecting ballast water, there should be a certain height difference between the deck barge surface and the waterline to ensure the safety and stability of the shipside transport vehicle when driving and loading / unloading the bridge to be installed.

[0109] In one embodiment, refer to the appendix to the specification. Figure 3 and Figure 4 According to another aspect of the present invention, the present invention further provides an inland river bridge installation system, comprising: a landside transport vehicle 31, a waterside transport vehicle 32, a bridge 1 to be installed, and a control terminal, wherein the landside transport vehicle 31 travels on land; the waterside transport vehicle 32 travels on a deck barge 2, the deck barge 2 connecting the two sides of the riverbank; the base of the bridge 1 to be installed can be mounted on the landside transport vehicle 31 and the waterside transport vehicle 32 respectively;

[0110] The control terminal is used to control each landside transport vehicle 31 to simultaneously transport the bridge to be installed to the first preset position; to control the landside transport vehicle 31 near the riverbank to transfer one end base of the bridge to be installed to the airside transport vehicle 32; to control the landside transport vehicle 31 near the riverbank to leave the construction site; and to control the landside transport vehicle 31 and the airside transport vehicle 32 to simultaneously transport the bridge to be installed to the second preset position along the direction of the deck barge 2.

[0111] It should be noted that after the landside transport vehicle 31 travels to the first preset position, one side base of the bridge 1 to be installed is close to or above the airside transport vehicle 32. After one side base is transferred from the corresponding landside transport vehicle 31 to the airside transport vehicle 32, the remaining landside transport vehicles 31 and airside transport vehicles 32 will continue to transport synchronously so that the bottom base of the bridge 1 to be installed is transported to the installation position, and one side base is transported by the airside transport vehicle 32 to cross the river.

[0112] In this embodiment, please refer to the appendix to the specification. Figure 5 and Figure 6 The deck barge 2 is fixed to the riverbanks on both sides by anchor cables. Before fixing, it is towed into the waterway for positioning by tugboats and other tools. After the bridge is installed, the corresponding anchor cables are removed and the deck barge 2 and the waterway transport vehicle 32 on it are towed away. The task is short and very quick.

[0113] In one embodiment, both the landside transport vehicle 31 and the airside transport vehicle 32 are equipped with lifting devices to adjust the relative position of the bridge 1 to be installed.

[0114] Construction workers can use the lifting device to adjust the height of the bridge 1 to be installed in real time during transportation. First, it can ensure the relative balance of the bridge 1 to be installed. If the bridge 1 to be installed becomes unstable or shifts to one side, it can be quickly adjusted to avoid construction accidents. Second, the overall operation is more flexible, and it is more convenient for construction workers to operate when installing and loading the bridge to be installed.

[0115] In one embodiment, based on the above embodiment, corresponding transport support fixtures 4 are respectively set between the bridge to be installed 1 and the landside transport vehicle 31, and between the bridge to be installed 1 and the airside transport vehicle 32. The transport support fixtures 4 are provided with transport vehicle entry positions to support the corresponding transport vehicles.

[0116] The transport support fixture 4 is designed and manufactured according to the size and weight of the bridge 1 to be installed and the on-site construction environment, so it has high reliability and high support performance. In addition, the top of the transport support fixture 4 is used to erect the bridge 1 to be installed, while the vehicle entry position is set at the bottom of the transport support fixture 4, which also facilitates the vehicle to drive in and out of the vehicle entry position. The bridge 1 to be installed can be moved by lifting or lowering the transport support fixture 4 to adjust the position of the bridge 1 to be installed.

[0117] 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.
