Description

[0002] The existing special engineering vessels used for transporting and sinking immersed tubes are usually catamaran structures. When transporting immersed tubes, the immersed tubes are transported between the two buoys of the catamaran, and the hull width of the engineering vessel is greater than the width of the immersed tubes it transports. However, in inland river immersed tube tunnel projects, since the construction area of ​​inland river immersed tube tunnels is generally located in inland waterways with shallow water depths and narrow channels, the hull width of the engineering vessel is limited by the width of the inland waterway, and the number of lanes and traffic volume of the immersed tube tunnel are determined by the width of the immersed tube. The larger the width of the immersed tube, the greater the traffic volume of the built immersed tube tunnel. Therefore, when the width of the immersed tube is large, the hull width of the required engineering vessel may exceed the width of the inland waterway and cannot be navigated. Therefore, how to provide a submerged tube transportation and sinking barge that can pass through narrow inland waterways and can transport large-width immersed tubes is a technical problem that urgently needs to be solved.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] As attached Figure 1-Figure 4 As shown, in an illustrative embodiment of a submerged tube transport and sinking barge of the present invention, the submerged tube transport and sinking barge includes a single hull 1, cantilever beams 2 arranged in pairs, and a submerged tube lifting and lowering device; the cantilever beams 2 arranged in pairs are symmetrically arranged on both sides of the single hull 1 in the width direction, and the cantilever beams 2 are cantilevered from the single hull 1 to the outside of the ship's side along the width direction of the single hull 1; the cantilever beams 2 are at least two pairs, and are symmetrically arranged relative to the center plane of the length direction of the single hull 1; the submerged tube lifting and lowering device includes sinking equipment 3 arranged one-to-one corresponding to the cantilever beams 2, the sinking equipment 3 is installed on the cantilever beams 2, and each sinking equipment 3 is commonly connected to the submerged tube 6 located below the single hull 1 to transport the submerged tube 6 and control the sinking and installation of the submerged tube 6; wherein the sinking equipment 3 corresponding to the cantilever beams 2 arranged in pairs are respectively connected to both sides of the width direction of the submerged tube 6.

[0039] The above-mentioned submerged tube transport and laying barge adopts a single hull 1, and a submerged tube lifting and laying device is carried by a cantilever beam 2 cantilevered outward from the side of the ship arranged on the single hull 1, so that the submerged tube 6 connected to the submerged tube lifting and laying device fits against the bottom of the single hull 1 for transportation. The width of the transported submerged tube 6 can be larger than the total width of the single hull 1 and the cantilever beams 2 on both sides thereof, so that the submerged tube 6 with a width close to the upper limit of the passage width of the inland waterway can be transported, thereby maximizing the utilization of the inland waterway width.

[0040] In order to maintain the force balance between the submerged tube 6 and the single hull 1 after the submerged tube 6 is connected, as shown in FIG. Figure 1 and Figure 2 As shown, preferably, at least a pair of cantilever beams 2 are respectively provided near the bow of the single hull 1 and near the stern of the single hull 1. When connecting the submerged tube 6, the sinking equipment 3 corresponding to the pair of cantilever beams 2 provided near the bow of the single hull 1 is respectively connected to the two sides of the axial end of the submerged tube 6 near the bow of the single hull 1, and the sinking equipment 3 corresponding to the pair of cantilever beams 2 provided near the stern of the single hull 1 is respectively connected to the two sides of the other axial end of the submerged tube 6 near the stern of the single hull 1, and the top surface of the submerged tube 6 is made to fit the bottom of the single hull 1 to fix the relative position of the submerged tube 6 and the single hull 1, so as to stably transport the submerged tube 6.

[0041] In order to be suitable for transporting immersed tubes 6 of different widths, preferably, the cantilever beam 2 is detachably connected to the single hull 1, so that a cantilever beam 2 of a suitable length can be selected according to the width of the immersed tube 6 to be transported.

[0042] like Figure 3 As shown, the cantilever beam 2 is provided with a hoisting opening a that passes through the cantilever beam 2 from top to bottom; the sinking equipment 3 includes a sinking winch 31, a sinking cable 32 and a fixed pulley 33, the fixed pulley 33 is installed at the hoisting opening a, the sinking winch 31 is arranged on the cantilever beam 2 and is located on the side of the hoisting opening a close to the single hull 1, one end of the sinking cable 32 is wound around the sinking winch 31, and the other end is bypassed around the fixed pulley 33 and then extends downward through the hoisting opening a to connect to the submerged tube 6. When sinking the submerged tube 6, the sinking winch 31 releases the sinking cable 32 to lower the submerged tube 6.

[0043] like Figure 3 As shown, one end of the cantilever beam 2 close to the single hull 1 is the lap end 22, and the other end is the cantilever end 21. The lap end 22 is lapped on the single hull 1, the sinking winch 31 is arranged on the lap end 22, and the lifting port a is opened at the cantilever end 21. In this embodiment, the cantilever beam 2 is overlapped with the single hull 1 through the lap end 22, so that the connection strength between the cantilever beam 2 and the single hull 1 can meet the force requirement of connecting the immersed tube 6. At the same time, the lifting port a where the fixed pulley 33 is installed is arranged at the cantilever end 21 of the cantilever beam 2, which can maximize the distance between the two connection points in the width direction of the immersed tube 6, thereby maximizing the width of the transported immersed tube 6. At the same time, the sinking winch 31 is arranged at the lap end 22, which is conducive to reducing the force on the cantilever beam 2.

[0044] like Figure 3 As shown, the overlapped end 22 is formed with a diagonal brace portion 23 connected to the single hull 1. The diagonal brace portion 23 can further strengthen the connection strength between the overlapped end 22 and the single hull 1.

[0045] Further, such as Figure 1-Figure 3As shown, the submerged tube transport and sinking barge also includes a mooring device, which includes mooring equipment 4 arranged near the four corners of the single hull 1. The mooring equipment 4 includes a mooring winch 41 and a mooring cable 42. The mooring winch 41 is arranged on the single hull 1. One end of the mooring cable 42 is wound around the mooring winch 41 and the other end is used to anchor on the bottom of the water. The mooring device can fix the position of the submerged tube transport and sinking barge when the submerged tube 6 is sunk.

[0046] like Figure 2 and Figure 3 As shown, a pair of cantilever beams 2 arranged near the bow of the single hull 1 and a pair of cantilever beams 2 arranged near the stern of the single hull 1 are respectively arranged in one-to-one correspondence with the mooring equipment 4 arranged at the four corners of the single hull 1. In the cantilever beams 2 and mooring equipment 4 arranged in one-to-one correspondence, the cantilever beams 2 are located on the outside of the length direction of the single hull 1, and the mooring equipment 4 is located on the inside of the length direction of the single hull 1, and a avoidance opening b for the mooring cable 42 to pass through is formed between the diagonal bracing portion 23 of the cantilever beam 2 and the end surface of its cantilever end 21. In this way, the cantilever beam 2 can be as close to the bow and stern of the single hull 1 as possible, so that the distance between the connection points in the length direction of the immersed tube 6 can be maximized, so as to maintain the force balance of the single hull 1 when transporting the immersed tube 6, and at the same time, the length of the transported immersed tube 6 can be maximized. In addition, by opening a avoidance opening b in the cantilever beam 2 for the mooring cable 42 to pass through, the interference between the mooring cable 42 and the cantilever beam 2 can be avoided.

[0047] like Figure 4 As shown, a buffer pad 5 is provided at the bottom of the single hull 1 for buffering the collision and friction between the submerged tube 6 and the bottom of the single hull 1 .

[0048] Based on the above-mentioned immersed tube transport and sinking barge, the present invention further provides an immersed tube transport and sinking construction method, which uses the above-mentioned immersed tube transport and sinking barge to carry out immersed tube transport and sinking construction, including the following steps:

[0049] Putting the immersed tube in place: placing the immersed tube 6 on the bottom of a dry dock filled with water; it should be noted that the immersed tube 6 can be placed on the bottom by injecting ballast water into the immersed tube 6;

[0050] The immersed tube transport and sinking barge is put into position: the immersed tube transport and sinking barge enters the dry dock and is put into position above the immersed tube 6. When in position, the direction of the immersed tube transport and sinking barge is adjusted so that the length direction of the single hull 1 is consistent with the length direction of the immersed tube 6;

[0051] Ship pipe connection: the submerged tube 6 is connected by the submerged tube hoisting device, and the submerged tube 6 is hoisted by the submerged tube hoisting device so that the submerged tube 6 is attached to the bottom of the single hull 1; it should be noted that when the submerged tube 6 is connected, the submerged cable 32 is lowered by the submerged winch 31, the submerged cable 32 is connected to the submerged tube 6 underwater, and the submerged cable 32 is reeled in by the submerged winch 31 to hoist the submerged tube 6. As the submerged tube 6 is hoisted, the ballast water in the submerged tube 6 is gradually discharged;

[0052] Transport and placement of immersed tube: The immersed tube 6 is transported to the preset placement position by the immersed tube transport and placement barge, and the immersed tube 6 is placed on the gravel bed by the immersed tube lifting and placing device.

[0053] The above-mentioned immersed tube transportation and sinking construction method has a simple construction process. In particular, when the ship pipe is connected, the immersed tube 6 is in a bottom-sitting state. The immersed tube 6 is lifted by a immersed tube lifting device, and the immersed tube 6 is fixed to the single hull 1 by utilizing the fit between the immersed tube 6 and the bottom of the single hull 1. When the ship pipe is connected, there is no need to accurately locate the position of the ship pipe, and the ship pipe connection process is simple.

[0054] 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.

[0055] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
