Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy projects, and in particular relates to a method for floating a submerged barge and a submerged tube. Background Art

[0002] In the construction of immersed tube tunnels, a sinking barge is usually used to transport and sink the immersed tubes (for example, the self-propelled underwater tunnel immersed tube transport and installation integrated vessel disclosed in patent CN106516021A). This sinking barge not only serves as a sinking platform but also acts as a buoyant body. It can use its own buoyancy to help adjust the draft of the immersed tube or give the immersed tube additional floating stability.

[0003] After the submerged tube is connected to the submerged barge, the barge's float and the submerged tube together form a composite unit with the following buoyancy characteristics: First, the combined weight of the submerged barge's float and the water displaced by the submerged tube equals the weight of the composite unit. If the composite unit's weight remains constant, an increase in the float's draft reduces the submerged tube's draft, and vice versa. Second, while maintaining freeboard, when the composite unit tilts, the freeboard decreases and a restoring moment is generated to resist the tilt. The greater the angle of tilt, the smaller the freeboard and the greater the restoring moment, giving the composite unit a strong resistance to capsizing. Third, after the freeboard is submerged, the restoring moment does not increase with increasing tilt angle, reducing the composite's resistance to capsizing. Because the submerged barge's float is located on either side of the submerged tube, the restoring moment generated by the water it displaces to resist the floating unit's tilt is greater than the restoring moment generated by the submerged tube displacing the same volume of water. Therefore, keeping the floating body of the submerged barge from being submerged so as to maintain the restoring moment of the submerged barge has a greater positive effect on the anti-overturning ability of the combination; in other words, keeping the floating body of the submerged barge with a larger freeboard height relative to the submerged tube has a greater positive effect on the wave resistance of the combination.

[0004] At present, in the floating transportation of submerged tubes, the relative size of the draft of the submerged barge and the submerged tube is usually adjusted by adjusting the weight of the ballast water in the submerged tube and the submerged barge, so as to maintain a larger freeboard height of the submerged barge relative to the submerged tube. However, filling and draining the tanks is a time-consuming process. It often takes several hours to complete a load adjustment and consumes a large amount of electricity, which makes it impossible to frequently adjust the load during the floating transportation of submerged tubes. It also puts high requirements on the water depth conditions of the construction waters and the dredging volume of the construction channel is large.

[0005] Therefore, how to quickly adjust the draft of the submerged barge float relative to the submerged tube is a technical problem that urgently needs to be solved. Summary of the Invention

[0006] In response to the above technical problems, the present invention provides a submerged barge and a method for floating a submerged tube. The submerged barge uses mechanical means to quickly adjust the draft of its floating body relative to the submerged tube. During the floating process of the submerged tube, it can quickly change its draft with the submerged tube according to the water depth and wave conditions, balance the shallow water passability and wave resistance of the floating transportation, reduce the requirements for the construction water area, and reduce the dredging volume of the construction channel.

[0009] Two buoys, symmetrically arranged on both sides of the deck width direction;

[0010] Two floating body connection devices are provided one-to-one with the two floating bodies and are symmetrically arranged on both sides of the deck width direction. The floating body connection devices are detachably connected between their corresponding floating bodies and the deck. Each floating body connection device includes at least one set of translation connection components, which include:

[0011] a first connecting rod and a second connecting rod, wherein two ends of the first connecting rod are hinged to the floating body and the deck respectively, and two ends of the second connecting rod are also hinged to the floating body and the deck respectively, the second connecting rod is located below the first connecting rod, the axis of the hinge axis between the floating body and the first connecting rod, the axis of the hinge axis between the floating body and the second connecting rod, the axis of the hinge axis between the deck and the first connecting rod, and the axis of the hinge axis between the deck and the second connecting rod are arranged parallel to each other, and the intersection points of the axes of the four hinge axes and a plumb bob plane constitute the four vertices of a parallelogram;

[0012] The telescopic rod is telescopic in length, and both ends of the telescopic rod are respectively hinged to the first connecting rod and the second connecting rod, and the two ends of the telescopic rod are respectively close to the floating body and the deck.

[0013] In some embodiments, the hinge between the telescopic rod and the first link shares the same hinge axis as the hinge between the first link and the deck, and the hinge between the telescopic rod and the second link shares the same hinge axis as the hinge between the second link and the floating body.

[0014] In some embodiments, one end of the first connecting rod hinged to the telescopic rod is Y-shaped, so as to be hinged to both sides of the telescopic rod respectively; one end of the second connecting rod hinged to the telescopic rod is Y-shaped, so as to be hinged to both sides of the telescopic rod respectively.

[0015] In some embodiments, the telescopic rod is a hydraulic rod.

[0016] In some embodiments, the float includes a rigid connection portion and a floating portion detachably connected to the bottom of the rigid connection portion, and the side portions of the rigid connection portion are hinged to the first connecting rod and the second connecting rod in the float connection device respectively.

[0017] In some embodiments, the float portion is composed of a plurality of float members that are detachably connected.

[0018] In some embodiments, each floating body connection device includes multiple sets of translational connection components, which are arranged side by side between the floating body and the deck along the length direction of the deck; in the multiple sets of translational connection components of each floating body connection device, multiple first connecting rods and the hinge axes of the floating body are coaxially arranged, multiple first connecting rods and the hinge axes of the deck are coaxially arranged, multiple second connecting rods and the hinge axes of the floating body are coaxially arranged, and multiple second connecting rods and the hinge axes of the deck are coaxially arranged.

[0019] In some embodiments, in each floating body connection device, the two first connecting rods of two adjacent groups of translation connection assemblies are fixedly connected by a first fixing rod, and the two second connecting rods of two adjacent groups of translation connection assemblies are fixedly connected by a second fixing rod.

[0020] In addition, the present invention also provides a method for floating a submerged tube, which adopts the submerged barge described in any of the above technical solutions to float the submerged tube, comprising the following steps:

[0021] Ship-pipe connection: connect the submerged pipe to be floated to the submerged barge so that the submerged pipe is located below the deck of the submerged barge and between the two floating bodies;

[0022] Floating transportation, with the state in which the bottom surface of the submerged tube is flush with the bottom surface of the floating body as the normal transportation state of the submerged barge, and the submerged tube is transported along the waterway by using the submerged barge in the normal transportation state; during the transportation process, if the wave height exceeds the set wave height and the water depth of the channel is greater than the set water depth of the channel, the telescopic drive deck of the telescopic rod is used to drive the submerged tube to descend relative to the floating body to increase the freeboard height of the floating body until the freeboard height of the floating body is greater than half of the wave height; when the wave height drops below the set wave height, or the water depth of the channel is reduced to the set water depth of the channel, the telescopic drive deck of the telescopic rod is used to drive the submerged tube to rise relative to the floating body to restore to the normal transportation state; wherein, twice the freeboard height of the submerged barge floating body when in the normal transportation state is taken as the set wave height, and the set water depth of the waterway is the water depth required for the submerged barge to safely pass with the submerged tube when in the normal transportation state.

[0023] In some embodiments, the specific steps of connecting the ship and the pipe are: using the telescopic drive of the telescopic rod to lift the deck to the highest position relative to the floating body, moving the sinking barge to straddle the submerged pipe to be floated, using the telescopic drive of the telescopic rod to lower the deck relative to the floating body to press down the submerged pipe, and connecting the submerged pipe to the lifting device carried on the deck.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are:

[0025] 1. The present invention provides a submersible barge, wherein the buoys on both sides are connected to the deck via a translational connection assembly. The first and second connecting rods in the translational connection assembly are hingedly connected to the buoy and the deck. The intersection of the axes of the four hinged shafts and the plumb plane forms the four vertices of a parallelogram. Furthermore, the extension and contraction of a telescopic rod hingedly connected between the first and second connecting rods changes the diagonal length and vertex angle of the parallelogram, restricting relative translational motion between the buoy and the deck within the plumb plane while locking all other degrees of freedom. This not only satisfies the need for relative vertical displacement between the buoy and the deck, thereby enabling adjustment of the draft difference between the submersible barge and the submerged tube, as well as the freeboard height of the buoy, but also maximizes the need for force transmission between the buoy and the deck.

[0026] 2. The submersible barge provided by the present invention can quickly change the draft difference between the submersible barge and the submerged tube and the freeboard height of the floating body according to the water depth and wave conditions when floating the submerged tube, thereby balancing the shallow water passability and wave resistance of the submerged tube, and has strong adaptability;

[0027] 3. The submersible barge provided by the present invention realizes the adjustment of the draft depth difference between the submersible barge and the immersed tube and the freeboard height of the floating body by mechanical means. The adjustment is quick and energy-saving. At the same time, the use of ballast is greatly reduced, the weight of the submersible barge is reduced, the draft depth of the combination of the submersible barge and the immersed tube is reduced, the requirements for the water depth conditions of the construction water area are lowered, the dredging amount of the construction channel is reduced, and the navigation resistance and energy consumption are reduced.

[0028] 4. The submerged tube floating method provided by the present invention can quickly change the draft of the submerged barge and the submerged tube and the freeboard height of the floating body according to the water depth and wave conditions when passing through waters with different water depths and wave conditions, thereby improving the safety of submerged tube floating and broadening the scope of application of construction waters.

[0043] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0045] The terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of such features.

[0046] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0047] like Figure 1-Figure 5 As shown, in an exemplary embodiment of the submerged barge of the present invention, the submerged barge includes a deck 1, two floating bodies 2 and two floating body connecting devices 3; the deck 1 is used to carry a hanging device connected to a submerged tube 4 (not shown in the figure); the two floating bodies 2 are symmetrically arranged on both sides of the width direction of the deck 1; the two floating body connecting devices 3 are arranged in a one-to-one correspondence with the two floating bodies 2 and are symmetrically arranged on both sides of the width direction of the deck 1, and the floating body connecting devices 3 are detachably connected between their corresponding floating bodies 2 and the deck 1, and each floating body connecting device 3 includes at least one set of translation connection components 31, and the translation connection components 31 include a first connecting rod 3101, a second connecting rod 3102 and a telescopic rod 3103 with a retractable length. 103; the two ends of the first connecting rod 3101 are hinged to the floating body 2 and the deck 1 respectively, the second connecting rod 3102 is located below the first connecting rod 3101, the axis of the hinge axis between the floating body 2 and the first connecting rod 3101, the axis of the hinge axis between the floating body 2 and the second connecting rod 3102, the axis of the hinge axis between the deck 3 and the first connecting rod 3101, and the axis of the hinge axis between the deck 3 and the second connecting rod 3102 are arranged parallel to each other, and the intersection of the axes of the four hinge axes and a plumb plane constitutes the four vertices of a parallelogram; the two ends of the telescopic rod 3103 are hinged to the first connecting rod 3101 and the second connecting rod 3102 respectively, and the two ends of the telescopic rod 3103 are close to the floating body 2 and the deck 1 respectively.

[0048] The working principle of the above-mentioned sinking barge is as follows: when floating the submerged tube 4, the submerged tube 4 is connected by the hanging device carried on the deck 1, so that the submerged tube 4 is located below the deck 1 of the submerged barge and between the two floating bodies 2; the floating body 2 is connected to the deck 1 through the floating body connecting device 3, and the length and shortening of the telescopic rod 3103 in the floating body connecting device 3 can change the diagonal length and vertex angle of the parallelogram with the intersection of the axes of the four hinged shafts at the two ends of the first connecting rod 3101 and the two ends of the second connecting rod 3102 and the plumb line as the vertex. Due to the limitation of the characteristics, the buoy 2 and the deck 1 connected at both ends of the first connecting rod 3101 and the second connecting rod 3102 can only perform relative translational motion within the plumb plane. At the same time, since the two hinge axes hinged to the buoy 2 are fixed relative to the buoy 2, and the two hinge axes hinged to the deck 1 are fixed relative to the deck 1, the translational motion between the buoy 2 and the deck 1 can change the relative positions of the buoy 2 and the deck 1 in the vertical direction, thereby realizing the adjustment of the draft depth difference between the submerged barge and the submerged tube 4 connected thereto and the adjustment of the freeboard height of the submerged barge buoy 2.

[0049] The above-mentioned submerged barge has the floating bodies 2 on both sides connected to the deck 1 through a translation connection assembly 31. The first connecting rod 3101 and the second connecting rod 3102 in the translation connection assembly 31 are hinged to the floating body 2 and the deck 1. The intersection of the axes of the four hinged shafts and the plumb plane constitutes the four vertices of a parallelogram. Then, by extending and shortening the telescopic rod 3103 hinged between the first connecting rod 3101 and the second connecting rod 3102, the diagonal length and the vertex angle of the parallelogram are changed, so that the floating body 2 and the deck 1 can only perform relative translational motion within the plumb plane, while all other degrees of freedom are locked. This not only meets the need for relative displacement between the floating body 2 and the deck 1 in the vertical direction, so as to realize the adjustment of the draft depth difference between the submerged barge and the immersed tube 4 and the freeboard height of the floating body 2, but also maximizes the need for force transmission between the floating body 2 and the deck 1. At the same time, when transporting the submerged tube 4, the aforementioned submerged barge can rapidly adjust the draft difference between the submerged tube 4 and the submerged tube 4, as well as the freeboard height of the buoy 2, according to water depth and wave conditions. This balances the shallow-water transportability and wave resistance of the submerged tube 4, demonstrating strong adaptability. Furthermore, the aforementioned submerged barge mechanically adjusts the draft difference between the submerged tube 4 and the freeboard height of the buoy 2, enabling rapid and energy-efficient adjustments. This significantly reduces the use of ballast, lightens the weight of the submerged barge, and reduces the draft of the combined submerged barge and submerged tube 4, lowering the depth requirements for the construction area and the amount of dredging required for the construction channel. Furthermore, it also reduces navigational resistance and energy consumption.

[0050] like Figure 3 and Figure 4As shown, the translation connection assembly 31 also includes a first articulated seat 3104, a second articulated seat 3105, a third articulated seat 3106 and a fourth articulated seat 3107; the first articulated seat 3104 and the second articulated seat 3105 are respectively fixedly connected to the two opposite sides of the floating body 2 and the deck 1, and the first articulated seat 3104 and the second articulated seat 3105 are respectively hinged to the two ends of the first connecting rod 3101 through the first pin 3108 and the second pin 3109; the third articulated seat 3106 and the fourth articulated seat 3107 are respectively fixedly connected to the two opposite sides of the floating body 2 and the deck 1, and the third articulated seat 3106 and the fourth articulated seat 3107 are respectively hinged to the two ends of the second connecting rod 3102 through the third pin 3110 and the fourth pin 3111. The first hinge seat 3104, the second hinge seat 3105, the third hinge seat 3106, and the fourth hinge seat 3107 cooperate with the first pin 3108, the second pin 3109, the third pin 3110, and the fourth pin 3111 to achieve an articulated connection between the first connecting rod 3101 and the second connecting rod 3102, the floating body 2, and the deck 1, resulting in a simple and reliable connection structure. It should be noted that the first hinge seat 3104 and the third hinge seat 3106 can be fixedly connected to the floating body 2 by welding or bolting, and the second hinge seat 3105 and the fourth hinge seat 3107 can be fixedly connected to the deck 1 by welding or bolting. Preferably, the first hinge seat 3104 and the third hinge seat 3106 are fixed on a vertical side of the float 2 facing the deck 1, and the second hinge seat 3105 and the fourth hinge seat 3107 are fixed on a vertical side of the deck 1 facing the float 2, so as to avoid affecting the relative movement between the float 2 and the deck 1. At the same time, when so arranged, the first connecting rod 3101 and the second connecting rod 3102 are preferably the same length.

[0051] like Figure 3 and Figure 4 As shown, the hinge connection between the telescopic rod 3103 and the first connecting rod 3101 shares the same hinge axis (specifically, the second pin 3109 in this embodiment) as the hinge connection between the first connecting rod 3101 and the deck 1. The hinge connection between the telescopic rod 3103 and the second connecting rod 3102 shares the same hinge axis (specifically, the third pin 3110 in this embodiment) as the hinge connection between the second connecting rod 3102 and the floating body 2. With this arrangement, the telescopic rod 3103 is arranged along the diagonal direction of the parallelogram, so that the relative movement between the floating body 2 and the deck 1 can be adjusted to the greatest extent by extending and retracting the telescopic rod 3103.

[0052] like Figure 3As shown, the hinged end of the first connecting rod 3101 and the telescopic rod 3103 is Y-shaped, so as to be hinged to both sides of the telescopic rod 3103. The hinged end of the second connecting rod 3102 and the telescopic rod 3103 is Y-shaped, so as to be hinged to both sides of the telescopic rod 3103. The Y-shaped hinged ends of the first connecting rod 3101 and the second connecting rod 3102 and the telescopic rod 3103 allow the telescopic rod 3103 to be connected from both sides, making the connection structure more stable.

[0053] like Figure 3 As shown, in this embodiment, the telescopic rod 3103 is a hydraulic rod. Figure 3 As shown, the hydraulic rod generally includes a cylinder body and a rod body that can be extended and retracted relative to the cylinder body. When the hydraulic rod is used as the telescopic rod 3103, in order to be able to retract to the shortest state, when hinged, the first connecting rod 3101 and the hydraulic rod are hinged at the end of the cylinder body close to the rod body, and the second connecting rod 3102 and the hydraulic rod are hinged at the end of the rod body away from the cylinder body; when hinged in this way, Figure 1 As shown, in order to avoid collision between the cylinder of the hydraulic rod and the deck 1, a receiving groove 101 for receiving the cylinder of the hydraulic rod is provided on the deck 1. It is understandable that those skilled in the art may also adopt telescopic rods of other structures.

[0054] like Figure 4 As shown, in this embodiment, the floating body 2 includes a rigid connection portion 21 and a floating portion 22 detachably connected to the bottom of the rigid connection portion 21. The side of the rigid connection portion 21 is hinged to the first connecting rod 3101 and the second connecting rod 3102 in the floating body connection device 3. The rigid connection portion 21 is used to connect to the floating body connection device 3 to improve the connection strength; the floating portion 22 is used to provide buoyancy. Preferably, as Figure 1 As shown, the floating portion 22 is composed of a plurality of detachably connected floating members 2201. Based on the tonnage of the immersed tube 4, an appropriate number of floating members 2201 can be selected and assembled to form the floating portion 22. It should be noted that in this embodiment, the floating body 2, the floating body connecting device 3, and the deck 1 are all detachably connected. The submerged barge can be disassembled for deployment and relocation, and then reassembled at the new construction site to form a submerged barge for the construction of the immersed tube 4, facilitating long-distance deployment and reducing deployment costs. The outer dimensions of the rigid connection portion 21 of the floating body 2 and the floating members 2201 can be designed according to the dimensions of standard containers. After disassembly, the floating body 2 can be deployed and relocated by container transportation.

[0055] like Figure 5As shown, each buoy connection device 3 includes multiple sets of translational connection assemblies 31, which are arranged side by side between the buoy 2 and the deck 1 along the length of the deck 1. In each buoy connection device 3, multiple first connecting rods 3101 are coaxially arranged with the hinge axis of the buoy 2, multiple first connecting rods 3101 are coaxially arranged with the hinge axis of the deck 1, multiple second connecting rods 3102 are coaxially arranged with the hinge axis of the buoy 2, and multiple second connecting rods 3102 are coaxially arranged with the hinge axis of the deck 1. By providing multiple sets of translational connection assemblies 31 to jointly connect the buoy 2 and the deck 1, and by adjusting the relative position of the buoy 2 and the deck 1 in the vertical direction through the joint action of the multiple sets of translational connection assemblies 31, the buoy 2 and the deck 1 can be firmly connected and better suited for floating larger submerged tubes 4.

[0056] like Figure 5 As shown, in each floating body connection device 3, the two first connecting rods 3101 of two adjacent sets of translational connection assemblies 31 are fixedly connected by a first fixing rod 32, and the two second connecting rods 3102 of two adjacent sets of translational connection assemblies 31 are fixedly connected by a second fixing rod 33. The provision of the first fixing rod 32 and the second fixing rod 33 to fixedly connect two adjacent sets of translational connection assemblies 31 allows multiple sets of translational connection assemblies 31 to be connected as one, which helps to improve the connection strength between the floating body 2 and the deck 1 and enhance the stability of the submerged barge.

[0057] Based on the above-mentioned sinking barge, the present invention further provides a method for floating a submerged tube, which uses the above-mentioned sinking barge to float a submerged tube 4, comprising the following steps:

[0058] S1 Ship-pipe connection: Connect the submerged pipe 4 to be floated to the submerged barge. During connection, the submerged pipe 4 is located below the deck 1 of the submerged barge and between the two floating bodies 2.

[0059] S2 floating: Figure 6 As shown, the state in which the bottom surface of the submerged tube 4 is flush with the bottom surface of the floating body 2 is regarded as the normal transport state of the submerged barge, and the submerged tube 4 is transported along the waterway using the submerged barge in the normal transport state; Figure 7As shown, during the transportation process, if the wave height exceeds the set wave height and the channel water depth is greater than the set channel water depth, the telescopic drive deck 1 of the telescopic rod 3103 is used to drive the immersed tube 4 to descend relative to the floating body 2 to increase the freeboard height of the floating body 2 until the freeboard height of the floating body 2 is greater than half of the wave height; when the wave height drops below the set wave height, or the channel water depth is reduced to the set channel water depth, the telescopic drive deck 1 of the telescopic rod 3103 is used to drive the immersed tube 4 to rise relative to the floating body 2 to restore to the normal transportation state; wherein, twice the freeboard height of the submerged barge floating body 2 in the normal transportation state is taken as the set wave height, and the set channel water depth is the water depth required for the submerged barge to carry the submerged tube 4 for safe passage in the normal transportation state.

[0060] The above-mentioned method of floating submerged tubes can quickly change the draft of the submerged barge and the submerged tube 4 and the freeboard height of the floating body 2 according to the water depth and wave conditions when passing through waters with different water depths and wave conditions, thereby improving the safety of floating submerged tubes and broadening the scope of application of construction waters.

[0061] It should be noted that the specific steps of connecting the ship pipes are: using the telescopic drive of the telescopic rod 3103 to lift the deck 1 relative to the floating body 2 to the highest position (such as Figure 8 As shown in the figure, the submerged barge is moved to straddle the submerged tube 4 to be floated. The telescopic rod 3103 is then extended and retracted to drive the deck 1 downward relative to the floating body 2 until it presses against the submerged tube 4. The submerged tube 4 is then connected to the lifting device carried on the deck 1. This method of connecting the ship and the tube can minimize collision between the submerged barge and the submerged tube 4 and facilitates the connection operation.

[0062] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0063] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the same. Although the present invention has been described in detail with reference to preferred embodiments, persons skilled in the art should understand that the specific implementation methods of the present invention may still be modified or some technical features may be replaced by equivalents without departing from the spirit of the technical solutions of the present invention, and all of these should fall within the scope of the technical solutions claimed for protection by the present invention.
