[0050] The terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features.

[0051] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0052] As shown in the drawings, Figures 1-4 In the first schematic embodiment of the immersed tunnel construction ship of the present application, the immersed tunnel construction ship comprises a single hull 1, a pair of cantilever beams 2, and an immersed tube launching device; the pair of cantilever beams 2 are symmetrically arranged on both sides of the single hull 1 in the width direction, and the cantilever beams 2 are cantilevered outward from the single hull 1 along the width direction of the single hull 1; a pair of cantilever beams 2 are arranged near the bow of the single hull 1 and near the stern of the single hull 1 respectively; the immersed tube launching device comprises an immersed tube launching device 3 corresponding to each cantilever beam 2, and the immersed tube launching device 3 is installed on the cantilever beam 2; each immersed tube launching device 3 is connected to the immersed tube 5 below the single hull 1 to transport the immersed tube 5 and control the launching and installation of the immersed tube 5; wherein the immersed tube launching devices 3 corresponding to the pair of cantilever beams 2 are connected to both sides of the immersed tube 5 in the width direction respectively.

[0053] The above-mentioned immersed tunnel construction ship is used for immersed tube transportation and launching construction, and the construction method comprises the following steps:

[0054] Immersion tube positioning: The immersed tube 5 is placed on the bottom in a dry dock filled with water; it should be noted that ballast water can be injected into the immersed tube 5 to make it sit on the bottom.

[0055] Positioning of the immersed tunnel construction vessel: The above-mentioned immersed tunnel construction vessel enters the dry dock and is positioned above the immersed tube 5. When positioning, the direction of the immersed tunnel construction vessel is adjusted so that the length direction of the single hull 1 is consistent with the length direction of the immersed tube 5.

[0056] Ship tube connection: The immersed tube 5 is connected by the immersed tube lifting device, and the immersed tube 5 is lifted by the immersed tube lifting device so that the immersed tube 5 is attached to the bottom of the single hull 1; it should be noted that as the immersed tube 5 is lifted, the ballast water in the immersed tube 5 is gradually discharged.

[0057] Immersed Tunnel Transportation and Placement: Immersed tunnel section 5 is transported to the pre-set placement location by the immersed tunnel construction vessel, and then placed onto the crushed stone foundation using the immersed tunnel lifting device.

[0058] The aforementioned immersed tunnel construction vessel adopts a single hull 1. The immersed tunnel lifting device is carried by the cantilever beam 2 that extends outward from the hull side of the single hull 1. The immersed tunnel 5 connected to the lifting device is attached to the bottom of the single hull 1 for transportation. The width of the immersed tunnel 5 transported can be greater than the total width of the single hull 1 and the cantilever beams 2 on both sides combined. Therefore, it can transport immersed tunnel 5 with a width close to the upper limit of the inland waterway passage width, which can maximize the use of the inland waterway width.

[0059] like Figure 3 As shown, the cantilever beam 2 has a lowering opening a through which it runs 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 lowering opening a. The sinking winch 31 is located on the cantilever beam 2 and on the side of the lowering opening a closer to the hull 1. One end of the sinking cable 32 is wrapped around the sinking winch 31, and the other end passes over the fixed pulley 33 and extends downward through the lowering opening a to connect to the immersed tube 5. When sinking the immersed tube 5, the sinking cable 32 is released by the sinking winch 31 to lower the immersed tube 5.

[0060] like Figure 3 As shown, the cantilever beam 2 has an overlapping end 22 near the single hull 1 and a cantilever end 21 at the other end. The overlapping end 22 overlaps with the single hull 1, and the sinking winch 31 is installed on the overlapping end 22. The lifting port a is opened at the cantilever end 21. In this embodiment, the cantilever beam 2 overlaps with the single hull 1 through the overlapping end 22, which ensures that the connection strength between the cantilever beam 2 and the single hull 1 meets the stress requirements for connecting the immersed tube 5. At the same time, setting the lifting port a, which is equipped with the fixed pulley 33, at the cantilever end 21 of the cantilever beam 2 maximizes the distance between the two connection points in the width direction of the immersed tube 5, thereby maximizing the width of the transported immersed tube 5. Meanwhile, setting the sinking winch 31 at the overlapping end 22 helps to reduce the stress on the cantilever beam 2.

[0061] As Figure 3 shown, the lap joint end 22 is formed with a bracing portion 23 supported on the single hull 1. The bracing portion 23 provided can further strengthen the connection strength between the lap joint end 22 and the single hull 1.

[0062] In addition, in order to be suitable for transporting different width immersed tubes 56, preferably, the cantilever beam 2 is detachably connected to the single hull 1, so as to select a suitable length of the cantilever beam 2 to be connected according to the width of the immersed tube 5 to be transported.

It should be noted that, as Figure 5 shown, the track 61 is located between the two pairs of cantilever beams 2 at the bow and the stern, so that the leveling device 6 works between the two pairs of cantilever beams 2 at the bow and the stern.

[0065] The immersed tunnel construction ship provided by the second exemplary embodiment of the utility model is used for not only immersed pipe transportation and sinking construction, but also gravel bed leveling construction, the method for gravel bed leveling construction is that: the direction of the immersed tunnel construction ship is adjusted to be perpendicular to the extension direction of the gravel bed to be leveled, the immersed tunnel construction ship is moved to the first working position at one end of the gravel bed to be leveled, the constraint frame 63 of the leveling device 6 drives the leveling actuator 64 to overturn in the vertical plane relative to the single hull 1 to the working state, the leveling pipe 641 is driven to lift by the lifting winch 6431 winding and unwinding the lifting traction rope 6432, so that the gravel bed below the current position of the leveling head 642 is leveled by the leveling head 642, the leveling actuator 64 is moved along the track 61 by the constraint frame 63 to complete the leveling operation at the current working position of the single hull 1; the immersed tunnel construction ship is gradually moved to the next working position in the direction of the other end of the gravel bed to be leveled, the leveling operation is carried out by the leveling device 6 at each working position, and the leveling operation of the gravel bed can be completed.
