Description

Technical Field

[0001] The invention belongs to the technical field of immersed tube tunnel construction, and in particular relates to a multifunctional ship for inland river immersed tube tunnel construction and a construction method thereof. Background Art

[0002] As a mode of transportation that quickly integrates into the urban expressway system and strengthens connections with the central urban area and the outside world, inland river immersed tube tunnels are an important factor affecting the development of regional economy and comprehensive transportation systems, and play an important supporting and guiding role in supporting regional urban construction and development.

[0003] The total length of an inland river immersed tube tunnel is generally short, but its construction process involves many social factors such as hydrological influence, navigation planning, water resource protection, urban planning, and traffic organization. Moreover, although the total length of an inland river immersed tube tunnel is short, its construction procedures have not been reduced. Its construction procedures include rough excavation of foundation trench, foundation treatment, fine excavation of foundation trench, block stone dumping, block stone tamping, crushed stone leveling, bed dredging, floating of immersed tube, installation of immersed tube, locking backfill, general backfill and face-changing backfill, etc. There are many water construction procedures, many ships and equipment required for construction, long operation time, and high risk of water operation. However, since the construction area of ​​an inland river immersed tube tunnel is generally located near an inland waterway with shallow water depth, narrow river channel, high flow rate, and more silt erosion and siltation, there are problems such as no working surface on site, the need for comprehensive closure of navigation, the inability to form a streamlined operation, and the inability of large ships to enter the inland waterway, which seriously affects the construction period and construction cost of the inland river immersed tube tunnel.

[0004] For the construction of inland river immersed tube tunnels, patent CN116716933A discloses a barge for gravel base bed leveling and immersed tube sinking and installation, which integrates the functions of gravel base bed leveling and immersed tube sinking and installation, and its hull adopts an assembled structure, which can meet the requirements of construction in the fourth-level inland waterway area; however, its hull needs to be completely newly built, the cost is relatively high, and it only reduces the use of leveling ships in the special ships required for the original construction. To complete the overall construction of the inland river immersed tube tunnel, it is still necessary to invest more special ships, and the construction cost is still relatively high.

[0005] Therefore, how to further reduce the ship configuration required for inland immersed tube tunnels to significantly reduce construction costs and improve water construction efficiency is a technical problem that urgently needs to be solved. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] As attached Figure 1-Figure 4As shown, in an illustrative embodiment of the multifunctional ship for inland river immersed tube tunnel construction of the present invention, the multifunctional ship for inland river immersed tube tunnel construction includes a hull 1, a block stone dumping operation unit, a block stone tamping operation unit, a crushed stone leveling operation unit and an immersed tube sinking and installation operation unit; the hull 1 includes a first operation barge 11, a second operation barge 12 and at least two connecting beams 13, the first operation barge 11 and the second operation barge 12 are arranged in parallel and in opposite directions, and the two connecting beams 13 are respectively detachably connected to the opposite bow and stern ends of the first operation barge 11 and the second operation barge 12. The rock throwing operation unit includes a rock throwing device 2, and the rock tamping operation unit includes a rock tamping device 3. Both the rock throwing device 2 and the rock tamping device 3 are carried on the side of the first working barge 11. When the hull 1 turns to a direction in which the length direction of the first working barge 11 is perpendicular to the extension direction of the immersed tube foundation 10 to be constructed and the first working barge 11 is closer to the initial working end of the immersed tube foundation 10 to be constructed than the second working barge 12, the rock throwing device 2 moves relative to the first working barge 11 along the length direction of the first working barge 11 to perform rock throwing. The stone tamping device 3 moves relative to the first working barge 11 along the length direction of the first working barge 11 to perform the stone tamping operation; the stone crushing and leveling operation unit includes a stone crushing and leveling device 4, which is carried on the side of the second working barge 12; when the hull 1 turns to a direction in which the length direction of the second working barge 12 is perpendicular to the extension direction of the submerged tube foundation 10 to be constructed and the second working barge 12 is closer to the initial working end of the submerged tube foundation 10 to be constructed than the first working barge 11, the stone crushing and leveling device 4 moves relative to the first working barge 11 along the length direction of the second working barge 12 to perform the stone tamping operation. The second working barge 12 moves to carry out stone crushing and leveling operations; the immersed tube sinking and installation operation unit includes four sets of sinking equipment 5, which are respectively arranged at the two ends of the two connecting beams 13; when the hull 1 turns to a direction in which the length direction of the first working barge 11 and the second working barge 12 is parallel to the extension direction of the immersed tube foundation 10 to be constructed, the four sets of sinking equipment 5 are respectively connected to the opposite sides of the axial ends of the immersed tube 6 and the immersed tube 6 is located between the first working barge 11 and the second working barge 12, so as to transport the immersed tube 6 and sink the immersed tube 6 onto the constructed immersed tube foundation 10.

[0061] In the above multifunctional ship for inland river immersed tube tunnel construction, it should be noted that the first working barge 11 and the second working barge 12 are of the same type, and the parameters such as the length, width, and depth of the two are consistent, so as to keep the hull 1 balanced during construction. Moreover, the first working barge 11 and the second working barge 12 can be modified from existing engineering square barges, and the existing engineering square barges are equipped with a block stone dumping operation unit and a block stone tamping operation unit as the first working barge 11, and the existing engineering square barges are equipped with a crushed stone leveling operation unit as the second working barge 12, thereby reducing the cost of the ship.

[0062] The above-mentioned multifunctional ship for inland river immersed tube tunnel construction carries the block stone filling operation unit and the block stone tamping operation unit through the first operation barge 11, carries the crushed stone leveling operation unit through the second operation barge 12, and carries the immersed tube sinking and installation operation unit through the connecting crossbeam 13. During construction, the switching of each operation unit is realized by turning the hull 1, so that the block stone filling, block stone tamping, crushed stone leveling, immersed tube floating and immersed tube installation processes can be completed in sequence by one ship, which can form a streamlined operation, greatly reduce the ship configuration required for inland river immersed tube tunnels, significantly reduce construction costs, and improve water construction efficiency. Moreover, the above-mentioned multifunctional ship for inland river immersed tube tunnel construction integrates the functions of block stone filling, block stone tamping, crushed stone leveling, immersed tube floating and immersed tube installation. The working surface required for its construction is small, and there is no need to close the waterway for navigation operations on the entire section, which reduces the social impact of the closure. Furthermore, in the above-mentioned multifunctional ship for inland river immersed tube tunnel construction, the block stone dumping operation unit and the block stone tamping operation unit are carried together on the first operation barge 11, and the crushed stone leveling operation unit is carried alone on the second operation barge 12. On the one hand, it is more conducive to maintaining the balance of the first operation barge 11 and the second operation barge 12, and on the other hand, it can reduce the number of turns of the hull 1 during the construction process, which is conducive to improving construction efficiency. In addition, the above-mentioned multifunctional ship for inland river immersed tube tunnel construction, its hull 1 is composed of the first operation barge 11, the second operation barge 12 and the connecting crossbeam 13. The first operation barge 11 and the second operation barge 12 can enter the construction site through the narrow inland waterway, and be assembled with the connecting crossbeam 13 at the construction site, which can meet the requirements of inland river immersed tube tunnel construction.

[0063] like Figure 1 and Figure 2 As shown, in this embodiment, the rock throwing equipment 2 and the rock tamping equipment 3 are both located on the ship side of the first working barge 11 away from the second working barge 12, and the crushed stone leveling equipment 4 is located on the ship side of the second working barge 12 away from the first working barge 11. Such arrangement of the rock throwing equipment 2, the rock tamping equipment 3 and the crushed stone leveling equipment 4 is more conducive to maintaining the balance of the hull 1. It can be understood that the rock throwing equipment 2 and the rock tamping equipment 3 can also be respectively carried on both sides of the first working barge 11 in this field, specifically: the rock throwing equipment 2 is located on the ship side of the first working barge 11 away from the second working barge 12, the rock tamping equipment 3 is located on the ship side of the first working barge 11 close to the second working barge 12, and the crushed stone leveling equipment 4 is located on the ship side of the second working barge 12 away from the first working barge 11. Such arrangement of the rock throwing equipment 2 and the rock tamping equipment 3 is more conducive to maintaining the balance of the first working barge 11.

[0064] like Figure 4 and Figure 5As shown, both ends of the connecting beam 13 are respectively hinged between the first working barge 11 and the second working barge 12 through the hinged supports 7 provided on the first working barge 11 and the second working barge 12. The connecting beam 13 is connected to the first working barge 11 and the second working barge 12 in a hinged manner, and can adapt to the different ups and downs of the first working barge 11 and the second working barge 12, so as to facilitate the assembly of the hull 1 on the water.

[0065] like Figure 2 and Figure 6 As shown, the first working barge 11 and the second working barge 12 are both provided with a limit assembly 8 for limiting the position of the connecting beam 13. The limit assembly 8 includes three limit stops surrounding the end of the connecting beam 13 from three sides, wherein the two limit stops located on the two opposite sides are the first limit stops 81, and the remaining limit stops are the second limit stops 82. The two first limit stops 81 are respectively against the two sides of the connecting beam 13 to limit the torsion of the connecting beam 13, and the second limit stops 82 are against the end face of the connecting beam 13 in the length direction to limit the movement of the connecting beam 13. The limit assembly 8 can effectively limit the torsion and movement of the connecting beam 13, thereby ensuring the overall stability of the multifunctional ship.

[0066] like Figure 7 and Figure 8As shown, in this embodiment, the bow end and the stern end of the first working barge 11 are respectively provided with a first trimming and loading water tank 111 and a second trimming and loading water tank 112, and the bow end and the stern end of the second working barge 12 are respectively provided with a third trimming and loading water tank 121 and a fourth trimming and loading water tank 122; a first loading adjustment pipeline is connected between the first trimming and loading water tank 111 and the second trimming and loading water tank 112, so that when the stone crushing and leveling equipment 4 moves, ballast water is allocated between the first trimming and loading water tank 111 and the second trimming and loading water tank 112 to maintain the first working barge 1 1 and the second working barge 12; a second load adjustment pipeline is connected between the third longitudinal tilt adjustment water tank 121 and the fourth longitudinal tilt adjustment water tank 122, so that ballast water can be allocated between the third longitudinal tilt adjustment water tank 121 and the fourth longitudinal tilt adjustment water tank 122 when the block stone throwing equipment 2 or the block stone tamping equipment 3 is moving, so as to maintain the balance of the first working barge 11 and the second working barge 12; the first working barge transverse tilt adjustment water tank 113 and the second working barge transverse tilt adjustment water tank 123 are also provided on the ship sides of the first working barge 11 and the second working barge 12 that are away from each other. In this embodiment, by respectively setting trim water tanks (including a first trim water tank 111, a second trim water tank 112, a third trim water tank 121 and a fourth trim water tank 122) at the bow and stern of a working barge (including a first working barge 11 and a second working barge 12), when the construction equipment (including a block stone dumping equipment 2, a block stone tamping equipment 3 and a crushed stone leveling equipment 4) of a working barge moves along the working barge to perform construction work, the trim of the hull 1 can be quickly reduced by allocating ballast water between the two trim water tanks arranged at the bow and stern of another working barge.
