Description

Technical Field

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

[0002] The construction of inland river immersed tube tunnels is limited by the width and depth of the inland waterway, and has high requirements on the tonnage and size of the construction ships. In order to reduce the requirements for the water depth and width of the waterway, the construction of inland river immersed tube tunnels usually adopts the form of a catamaran combined ship. After two single ships enter the construction area, the two hulls are connected by a crossbeam to form a combined ship for the installation of the immersed tube.

[0003] At present, patent CN110053720A discloses a combined immersed tube transport and installation barge. After the two hulls are in place at the construction site, a crossbeam is connected between the two hulls by means of tethers to form a catamaran combined ship for inland river immersed tube tunnel construction. However, although the use of tethers to connect the crossbeam and the hull is convenient for assembly and disassembly, the tether connection is a flexible connection, and relative displacement between the crossbeam and the hull is prone to occur, resulting in deformation of the combined ship. Moreover, the connection strength of the tether connection is low and it is easy to be damaged, resulting in construction accidents. Patent CN219134453U discloses a variable width semi-submersible immersed tube floating installation barge, in which the crossbeam and two hulls are connected by bolts. Although relative displacement between the crossbeam and the hull can be avoided, since the two hulls may rise and fall inconsistently due to the influence of waves, the crossbeam and the hull are connected by bolts, so that the crossbeam and the hull are completely rigidly connected as one. The crossbeam will be subjected to great shear or torsion. In order to avoid damage to the crossbeam, one solution is to increase the width of the crossbeam to increase the cross-sectional area of ​​the crossbeam. Another solution is to use a highly rigid material to make the crossbeam, but both of these treatment methods will lead to an increase in the manufacturing cost of the combined ship, and will cause the weight of the beam to increase, making it difficult to transport and assemble.

[0004] The hinged connection is a flexible connection method between flexible connection and completely rigid connection. It is used to connect the crossbeam and the hull of a catamaran combined ship for inland immersed tube tunnel construction. It can reduce the shear or torsion force on the crossbeam while avoiding deformation of the catamaran combined ship. However, the length of the crossbeam is much larger than the width of a single ship, and the weight of the crossbeam is heavy. In addition, the fitting clearance of the hinged connection is extremely small. Therefore, it is extremely technically difficult to achieve an hinged connection between the crossbeam and the two hulls in the rough sea environment. Summary of the invention

[0044] As attached Figure 1 As shown, an exemplary embodiment of the present invention provides a method for assembling a multifunctional ship for inland river immersed tube tunnel construction with a hinged cross beam, comprising the following steps:

[0045] S1 Single work barge in place: Two work barges 1 constituting a multifunctional ship for inland river immersed tube tunnel construction are moored at the pier 2, wherein articulated seats 101 for articulating the cross beam 7 are respectively provided on the deck of the work barge 1 near the bow and stern ends; when docked, the two work barges 1 are parallel to each other and the articulated seats 101 at both ends are respectively opposite, and the relative position relationship of the two work barges 1 is maintained within the set relative position relationship range required for installing the cross beam 7, and the ballast water of the two work barges 1 is adjusted so that the two work barges 1 are in a positive floating state and the difference in draft depth is less than the preset draft deviation;

[0046] S2 Rough positioning and installation of the crossbeam: Use the crane ship 6 to lift the crossbeam 7 to be installed, and the bottoms of both ends of the crossbeam 7 are respectively provided with hinge plates 701 for hinged hinge seats 101; Use the crane ship 6 to move the crossbeam 7 to cross over the two working barges 1, and lower the crossbeam 7 so that the hinge plates 701 at both ends of the crossbeam 7 are respectively inserted into the corresponding hinge seats 101 set on the working barge 1; Use the crane ship 6 to adjust the height of the crossbeam 7 and the distance between the two working barges 1 so that the position of the crossbeam 7 is adjusted to the range of the rough installation position set near the predetermined installation position of the crossbeam; Use the temporary pin shaft 8 as the hinge shaft to penetrate the hinge plate 701 and its corresponding hinge seat 101, wherein the diameter of the temporary pin shaft 8 is smaller than the diameter of the formal pin shaft 10;

[0047] S3 beam precision positioning installation: after all beams 7 to be installed are roughly positioned and installed, install the beam position precision adjustment tool 9 at the end of the beam 7, and install the pin push tool 11 on the deck on one side of the articulated seat 101; pull out the temporary pin 8, place the formal pin 10 on the pin push tool 11, use the beam position precision adjustment tool 9 to adjust the position of the beam 7 to the predetermined installation position of the beam, and use the pin push tool 11 to push the formal pin 10, so that the formal pin 10 penetrates the articulated plate 701 and its corresponding articulated seat 101, and completes the articulated connection between the beam 7 and the working barge 1. It should be noted that in this step, the temporary pins 8 are replaced with the formal pins 10 one by one, and the corresponding temporary pins 8 are pulled out before each formal pin 10 is installed, and the other temporary pins 8 remain unchanged.

[0048] The assembly method of the multifunctional ship for inland river immersed tube tunnel construction with the hinged crossbeam is as follows: first, the relative position relationship of the two working barges 1 to be connected is adjusted to be kept within the set relative position relationship range required for installing the crossbeam 7, and the buoyancy and draft of the two working barges 1 are adjusted to make the two working barges 1 maintain the same floating state as much as possible, and then the crossbeam 7 is hoisted into place by the crane ship 6, and the rough positioning installation of the crossbeam 7 is realized by the temporary pin shaft 8. When all the crossbeams 7 to be installed are roughly positioned and installed, the two working barges 1 are synchronized by the restriction of the crossbeam 7. The temporary pins 8 are replaced with formal pins 10 one by one to complete the precise positioning and installation of the beams. When the temporary pins 8 are pulled out, the beam position fine-tuning tool 9 is used to accurately adjust the position of the beam 7 relative to the hinge seat 101, and then the formal pins 10 are placed on the pin pushing tool 11, and the formal pins 10 are pushed by the pin pushing tool 11 to install the formal pins 10 in place, thus realizing the articulated connection between the beam 7 of the multifunctional ship for inland river immersed tube tunnel construction and the two working barges 1. The above-mentioned assembly method of the multifunctional ship for inland river immersed tube tunnel construction with an articulated beam realizes the efficient and precise articulation between the beam 7 of the multifunctional ship for inland river immersed tube tunnel construction and the two working barges 1 in the rough sea environment, and has low construction risks and low construction costs.

[0049] Regarding the S1 single-operation barge placement steps, it should be noted that Figure 2 As shown, when the two working barges 1 are moored at the pier 2, they can be moored along the extension direction of the pier 2, wherein one working barge 1 is moored at the pier 2 and the other working barge 1 is anchored. Figure 3 As shown, when the two working barges 1 are moored at the pier 2, they can be moored in a direction perpendicular to the pier 2, with one end of the working barge 1 in the length direction moored at the pier 2 and the other end anchored.

[0050] In order to facilitate the regulation of the relative position relationship between the two working barges 1, Figure 2 and Figure 3 As shown, after the two working barges 1 are moored, an adjusting cable 3 is connected between the ends of the two working barges 1 that are diagonally opposite to each other, and the two adjusting cables 3 cross each other. By adjusting the length of the adjusting cable 3 and the length of the mooring cable 5 of the working barge 1, the relative position relationship of the two working barges 1 is adjusted. It should be noted that the length of the mooring cable 5 is adjusted by using an anchor machine connected to the mooring cable 5, and a hand winch 4 is installed at one end of the adjusting cable 3, and the length of the adjusting cable 3 is adjusted by using the hand winch 4.

[0051] Specifically, in the step of positioning a single work barge 1, the distance between the two work barges 1 and the length of the two diagonals are measured by a preset ruler and a laser theodolite, wherein the diagonal refers to the line between the ends of the two work barges 1 that are diagonally opposite to each other; the distance between the two work barges 1 is controlled to be maintained at the preset distance, and the length difference of the two diagonals is controlled to be less than the preset diagonal deviation, so that the relative position relationship of the two work barges 1 is maintained within the set relative position relationship range. It should be noted that the preset distance is determined according to the length of the crossbeam 7, the position of the hinged plates 701 at both ends of the crossbeam 7, and the position of the hinged seat 101 on the work barge 1. In this embodiment, the preset distance is set to 43~44m; the preset diagonal deviation is preferably 0.5m.

[0052] When adjusting the draft of the two working barges 1, the ballast water systems of the two working barges 1 are used to adjust the draft of the working barges 1, and the draft of the two working barges 1 is preferably adjusted to about 2 meters. The preset draft deviation is preferably 100mm, so that the two working barges 1 can maintain the same floating state as much as possible.

[0053] Regarding the rough positioning and installation steps of the S2 beam, it should be noted that the beam 7 to be installed can be transported to the construction site with the working barge 1, and the beam 7 can be lifted from the working barge 1 by the crane ship 6. After the crane ship 6 lifts the beam 7, it slowly lifts it to a distance of more than 1m from the deck and leaves it still for 5 minutes. After the beam 7 is stable, the crane ship 6 slowly adjusts the plane and moves to the side of the working barge 1 where the beam 7 is to be installed. It is understandable that after the crane ship 6 lifts the beam 7 from a working barge 1, the draft of the working barge 1 needs to be readjusted so that the two working barges 1 are in a positive floating state and the difference in draft is less than the preset draft deviation.

[0054] In order to improve the rough positioning and installation efficiency of the crossbeam 7, Figure 4-Figure 7 As shown, the articulated seat 101 includes a pair of articulated plates 1011 for articulation and a support 1012 connected between the two articulated plates 1011; in the step of rough positioning and installation of the cross beam, when the articulated plate 701 is inserted into the articulated seat 101, the articulated plate 701 is located between the two articulated plates 1011 and supported on the support 1012. The articulated seat 101 with the above structure can guide the articulated plate 701 to be quickly inserted into the articulated seat 101 through the articulated plate 1011; the articulated plate 701 is supported by the support 1012, which can roughly position the cross beam 7 in the vertical direction on the one hand, and reduce the load of the crane ship 6 on the other hand, so as to facilitate the rapid adjustment of the cross beam 7 to the set rough installation position range. It should be noted that after the two articulated plates 701 at both ends of the cross beam 7 are inserted into the corresponding articulated seat 101, the temporary pin 8 is installed.

[0055] In order to facilitate the adjustment of the position of the crossbeam 7 to within the set rough installation position range, Figure 4As shown, the articulated seat 101 is provided with a first through hole a for the articulated pin to pass through, and the articulated plate 701 is provided with a second through hole b for the articulated pin to pass through; in the step of rough positioning and installation of the crossbeam, when adjusting the height of the crossbeam 7, when the distance between the center line of the first through hole a of the articulated seat 101 and the center line of the second through hole b of the articulated plate 701 is less than the preset center deviation, it is determined that the height of the crossbeam 7 is within the rough installation position range; the diameter difference between the temporary pin 8 and the formal pin 10 is greater than or equal to the preset center deviation. Preferably, the preset center deviation is 10 cm. It should be noted that in the process of adjusting the position of the crossbeam 7, the ballast water of the two working barges 1 is adjusted in real time to control the two working barges 1 to always be in a positive floating state and the difference in draft depth is always less than the preset draft deviation.

[0056] It should also be noted that after temporary pins 8 are installed at the two hinged plates 701 at both ends of a beam 7, the crane vessel 6 is gradually unloaded (10%-20% each time), and the two work barges 1 cooperate to adjust the ballast water to keep the work barge 1 in a positive floating state until the load of the crane vessel 6 drops to zero tonnage. The crane vessel 6 moves to the other side of the work barge 1 to perform rough positioning and installation of another beam 7 to be installed.

[0057] Regarding the S3 beam precision positioning and installation steps, it should be noted that when the height of the beam 7 is adjusted using the beam position precision adjustment tool 9, when the center line of the second through hole b of the hinge plate 701 connected to the beam 7 is colinear with the center line of the first through hole a of the hinge seat 101, it is determined that the height of the beam 7 is at the predetermined installation position of the beam.

[0058] like Figure 8As shown, the crossbeam position fine adjustment tool 9 includes a vertical push piece 901, a reaction piece 902 and a pair of transverse push pieces 903; the vertical push piece 901 is installed between the deck of the work barge 1 and the end of the crossbeam 7, and is retracted in the vertical direction; the reaction piece 902 is installed on the top edge of the outer side of the hinge seat 101, and extends in the vertical direction to the outer side of the hinge plate 701 inserted into the hinge seat 101; the transverse push piece 903 is connected between the outer side of the hinge plate 701 and the reaction piece 902, and the two transverse push pieces 903 arranged in pairs are relative to each other. The reaction piece 902 is symmetrically arranged, and the horizontal push piece 903 is extended and retracted in the horizontal direction; in the step of precise positioning and installation of the crossbeam, the height of the crossbeam 7 is adjusted by the extension and retraction of the vertical push piece 901 in the vertical direction, and one of the paired horizontal push pieces 903 is contracted in the horizontal direction and the other horizontal push piece 903 is synchronously extended in the horizontal direction, so as to adjust the position of the crossbeam 7 relative to the hinge seat 101, so that the center line of the second through hole b of the hinge plate 701 connected to the crossbeam 7 is in line with the center line of the first through hole a of the hinge seat 101. The crossbeam position fine adjustment tool 9 with the above structure can adjust the height of the crossbeam 7 in the vertical direction and the position of the crossbeam 7 in the horizontal direction relative to the two working barges 1, so that the crossbeam 7 can be quickly adjusted into place. It should be noted that the vertical push piece 901 and the horizontal push piece 903 can both use hydraulic cylinders, and the reaction piece 902 can use a reaction block welded on the hinge plate body 1011 of the hinge seat 101.

[0059] In order to facilitate the use of the pin push tool 11 to install the formal pin 10 in place, Fig. 9 As shown, in the precise positioning and installation steps of the crossbeam, the placement position of the pin shaft pushing tooling 11 for placing the formal pin shaft 10 is opposite to the first through hole a of the hinge seat 101, and the pushing direction of the pin shaft pushing tooling 11 is consistent with the extension direction of the center line of the first through hole a; the specific steps of using the pin shaft pushing tooling 11 to push the formal pin shaft 10 are: adjust the height of the pin shaft pushing tooling 11 so that the center line of the formal pin shaft 10 is colinear with the center lines of the first through hole a and the second through hole b, and use the pin shaft pushing tooling 11 to push the formal pin shaft 10 into the first through hole a and the second through hole b.

[0060] like Fig. 9As shown, the pin push tool 11 includes a support platform 1101, a pin push piece 1102 arranged on the support platform 1101, and an adjusting screw 1103 for adjusting the height of the support platform 1101; a placement position for placing the formal pin 10 is provided on the support platform 1101, and the pin push piece 1102 is arranged on one side of the placement position and pushes in the direction of the placement position; a flange portion c is provided on the outer periphery of the bottom of the support platform 1101, and the axis of the adjusting screw 1103 is arranged in the vertical direction. The adjusting screw 1103 is threadedly connected to the flange portion c and passes through the bottom surface of the flange portion c in the vertical direction to support the deck of the working barge 1. The pin push tool 11 with the above structure, with the support platform 1101 as support, can quickly adjust the height of the formal pin 10 by using the adjusting screw 1103, and then the formal pin 10 can be installed in place in one step by using the pin push piece 1102. It should be noted that, in this embodiment, three steel piers are arranged in parallel to form the support platform 1101, and a pair of adjusting screws 1103 are arranged on both sides of each steel pier to adjust the height and pitch angle of the support platform 1101, so as to ensure that the formal pin shaft 10 placed on the support platform 1101 can be adjusted into place. In addition, in this embodiment, a hydraulic cylinder is used as the pin shaft pushing member 1102, so as to facilitate pushing the formal pin shaft 10, so that the formal pin shaft 10 can be installed in place in one step.
