The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.

As shown in fig. 1 to 5, an embodiment of the present application provides a immersed tube carrier 1 (hereinafter, may be simply referred to as an immersed tube carrier) having a tube connection device. The submerged pipe carrier 1 has hulls 101 on opposite sides and a bridge 102 connected between the two hulls 101.

The immersed tube carrier 1 is further provided with a tube connection device 2 which can be floated and sunk with the immersed tube carrier 1. The ship pipe connecting device 2 is arranged on the immersed pipe transporting ship 1, is positioned between the immersed pipe transporting ship 1 and the immersed pipe 5, and can be used for lifting and lowering the immersed pipe 5.

As shown in fig. 6 and 7, the ship's pipe connection device 2 has a cross member 201, and a suspension post 202 is provided on the cross member 201, which extends downward in a direction substantially perpendicular to the cross member 201.

In one embodiment, the first end 2021 of the suspension post may be fixedly mounted to the cross member 201.

In another alternative embodiment, as shown in fig. 5 and 9, the first end 2021 of the suspension post is slidably coupled to the cross beam 201. Optionally, a driving device (not shown in the figure) capable of driving the suspension post 202 to move along the beam 201 and a limiting device (not shown in the figure) for limiting the excessive movement of the suspension post 202 on the beam 201 are provided between the suspension post 202 and the beam 201. For example, the driving device may be a hydraulically driven push rod, the support part of which is mounted on the cross beam 201, the push rod being connected to the suspension post 202 to push the suspension post 202 into motion. The limiting device can be a block which can extend and retract on the surface of the cross beam, and when the suspension post 202 needs to move on the cross beam 201 to adjust the position, the block is retracted into the surface of the cross beam and does not block the left-right movement of the suspension post 202; when the suspension post 202 is in place, the blocks extend beyond the surface of the cross beam, defining the position of the suspension post 202.

As shown in fig. 6 and 7, a second end 2022 of the suspension post opposite to the first end 2021 of the suspension post is provided with a recess 2023, in which a hook 203 is provided, and the hook 203 may be connected to the suspension post 202 through a rotation shaft such as a pin 204 so as to be rotatable to protrude or be received upward in the recess 2023. The second end 2022 of the suspension post is further provided with a rotation stop block 205 located at the lower portion of the hook 203, which can define the limit position for the hook 203 to turn down and provide a supporting counter force.

The hook 203 may be controlled using a rotational actuator (e.g., an electric actuator) such that it may rotate relative to the pin 204 to extend out of or be received in the recess 2023. The driving technique is conventional in the art, and driving can be achieved by adopting the existing means.

When the hooks 203 are extended, the vessel pipe connection device 2 is substantially t-shaped (as shown in fig. 5); when the hooks 203 are retracted, the vessel pipe connection device 2 is substantially "T" shaped.

As shown in fig. 3 to 5, the immersed tube 5 is provided with a reverse bracket 501 at a side near the boat pipe connecting device 2, and a receiving groove 502 capable of receiving the hanging hook 203 is formed on the immersed tube 5, so that the immersed tube 5 can be lifted up and down together with the boat pipe connecting device 2.

As shown in fig. 4 and 5, the connection device further comprises a buttress 3 and a cushion pier 4.

In the working state, the buttress 3 is positioned between the cross beam 201 and the immersed tube 5; more specifically, the buttress 3 is located at the end of the beam 201 remote from the hull 101; so that the piers 3 can provide supporting force at opposite ends to prevent the transom 201 from overturning when the immersed tube carrier 1 moves upward to drive the transom 201. The buttress 3 may be selected from components such as concrete, wood, steel, etc.

In some embodiments, the top surface of immersed tube 5 or the bottom surface of beam 201 may be provided with a first positioning groove (not shown), and pier 3 may be restricted in the first positioning groove to prevent pier 3 from being deviated during transportation, etc.

In some embodiments, the buttress is a mechanism which is fixedly arranged on the bottom surface of the cross beam and can extend up and down, such as a hydraulic jack with a rubber pad at the free end, and the like, so that the buttress can be supported between the immersed tube and the cross beam on one hand, and the immersed tube can be prevented from being damaged due to the arrangement of the rubber pad on the other hand.

The ship pipe connecting device 2 bears a large load, especially the load can reach hundred tons when the immersed pipe 5 is lifted to reduce the draft, and the T-shaped structure with the buttress 3 can enable the connecting device to keep self-stability under the stress state that the load of the reverse bracket and the lifting force of the ship body to the cross beam are not collinear.

As shown in fig. 4 and 5, in the working state, the cushion pier 4 is located between the beam 201 and the bridge frame 102, and plays a role in supporting and buffering, so that the immersed tube carrier 1 and the carrier tube connecting device 2 are fastened together in the process of transportation, and the transportation stability is improved. The cushion pier 4 may be selected from a concrete, wood, steel, etc.

In some embodiments, the top surface of the beam 201 or the bottom surface of the bridge frame 102 may be provided with a second positioning groove (not shown in the drawings), and the cushion pier 4 may be limited in the second positioning groove, so as to prevent the cushion pier 4 from being deviated during transportation, etc.

In some embodiments, the pad pier may also be fixedly mounted to the top surface of the beam and/or the bottom surface of the bridge frame.

The ship pipe connection device 2 enables the whole transportation system to be stable under the action constraint of lifting force and immersed pipe load. The pad pier 4 mainly has the function of increasing the stability of the ship pipe connecting device 2 and the immersed pipe 10 under severe sea conditions, and can be not arranged in a water area with good sea conditions.

As shown in fig. 1 to 5, in one embodiment, each two ship pipe connection devices 2 are formed as a pair, symmetrically disposed at both sides of the immersed pipe, and respectively mounted on two ship bodies 101 of the immersed pipe carrier 1. The immersed tube carrier 1 may have a plurality of pairs of tube connection devices 2.

In one embodiment, as shown in fig. 8 and 9, each pair of ship pipe connection devices 2 shares a cross beam 201, which cross beam 201 extends from the inner side of one hull to the inner side of the other hull.

The beam 201 is connected into a whole, so that the rigidity and bearing capacity of the beam 201 can be exerted, and the stability of a stress system is enhanced; however, in the case of a larger immersed tube width, the length of the cross beam may be increased more; the choice of the specific solution allows to take into account a compromise between the enhancement of the structural properties and the economy.

The construction method of the immersed tube transport ship comprises the following steps:

S1 riding span: towing the immersed tube 5 to a position between two hulls 101 of the immersed tube carrier 1 so that the immersed tube carrier 1 rides over the immersed tube 5 (i.e., the two hulls 101 are positioned on both sides of the immersed tube 5 and the bridge 102 is positioned over the immersed tube 5);

S2, hooking: when the lifting hook 203 is configured to be rotatable, ballast water is added into the hull 101 to enable the immersed tube carrier 1 to sink, the cross beam 201 follows the sinking, the lifting hook 203 is lower than the bearing surface of the reverse bracket 501, and the lifting hook 203 is turned down to enter the accommodating groove 502; or alternatively

S2, hooking: when the suspension post 202 is configured to be slidable on the cross beam 201, ballast water is added into the hull 101 to cause the immersed tube carrier 1 to sink, the cross beam 201 follows the descent, the lifting hook 203 is lower than the bearing surface of the reverse bracket 501, and the suspension post 202 is pushed to the immersed tube side to cause the lifting hook 203 to enter the accommodating groove 502;

S3, pre-lifting: discharging ballast water from the ship body 101, so that the ship body 101 floats upwards to drive the cross beam 201 to ascend, and the lifting hooks 203 are abutted against the bearing surfaces of the brackets 502;

s4, supporting: supporting the buttress 3 between the cross beam 201 and the immersed tube 5;

S5, lifting: continuously discharging ballast water from the ship body 101 to enable the ship body 101 to float upwards, continuously driving the cross beam 201 to ascend, and lifting the immersed tube 5 to a preset position;

s6, supporting pad: the cushion pier 4 is supported between the bridge frame 102 and the beam 201.

In S2, different treatment modes may be selected according to different structures of the suspension post 202 and the suspension hook 203. When the lifting hook 203 is rotatable and the lifting column 202 is also movable left and right, then it may be necessary to simultaneously turn the lifting hook 203 downwards and push the lifting column 202 towards the tube sinking side when the lifting hook 203 is below the bearing surface of the counter bracket 501, so that the lifting hook 203 enters the receiving groove 502 and is able to lift the tube sinking. In the non-working state, the lifting hook 203 can be upwards turned around the pin shaft to be accommodated in the groove 2023, so as to realize separation and sinking installation of the immersed tube and the transport ship; or in the non-working state, the lifting column 202 slides along the cross beam 201 in a direction away from the immersed tube 5, so that the lifting hook 203 is separated from the accommodating groove 502, and separation and sinking installation of the immersed tube and the transport ship are realized.

The above embodiments are merely illustrative of the preferred embodiments of the present application and are not intended to limit the scope of the present application, and various modifications and improvements made by those skilled in the art to the technical solution of the present application should fall within the protection scope defined by the claims of the present application without departing from the spirit of the design of the present application.
