[0002] The tunnel construction process using the immersed tube method mainly includes pipe segment prefabrication, undocking, floating, sinking and installation, and construction inside the pipe, among which pipe segment floating is easily affected by the water flow velocity, floating distance, channel depth and width, and distribution of water structures in the construction waters. In long-distance routes with limited dimensions in complex sea areas, it is very important to control the track line of the pipe segment for long-distance wet towing of low freeboard curved widened pipe segments.

[0003] In view of the objective situation of low freeboard of the immersed tube, the traditional connection between the tugboat and the pipe segment is a tow cable soft connection.

In addition, since the tugboat needs to be connected to the pipe segment, during the construction of the pipe segment body, embedded parts need to be installed on the pipe segment body to connect it to the tugboat through the embedded parts, making the construction of the pipe segment body complicated.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] like Figure 1 to Figure 14 As shown, this embodiment provides a floating auxiliary device, which is used to apply the towing force of the tugboat directly to the submerged barge, and the submerged barge is placed on the pipe segment. The floating auxiliary device includes a base 1 and a pushing tool 2, wherein the base 1 is fixed on the submerged barge; the pushing tool 2 includes a frame 21, which is detachably connected to the base 1, and a plurality of mooring piles 211 are arranged on the frame 21, and the mooring piles 211 are detachably connected to the tugboat. The floating auxiliary device can efficiently and accurately control the track line of the pipe segment, and can reduce the construction amount of the pipe segment body.

[0041] Preferably, the frame 21 is connected to the base 1 by bolts. Further preferably, the mooring pile 211 on the frame 21 is fastened to the tugboat by a cable.

[0042] The base 1 is installed on the submerged barge for easy disassembly and reuse. Specifically, the base 1 is welded on the submerged barge before the first pipe section is floated, and the top-pushing fixture 2 is connected to the base 1 by bolts. After the first pipe section is floated, the top-pushing fixture 2 can be easily disassembled. When the next pipe section is floated, it is only necessary to reconnect the top-pushing fixture 2 to the base 1 by bolts, and there is no need to weld the base 1 on the submerged barge again. During the floating process, a tugboat is set in front of and behind the pipe section, and the main power is provided by tying and towing the main system mooring column of the pipe section. A tugboat is arranged on each side of the two submerged barges, and the four tugboats adjust the forward direction by tying and towing or pushing the floating auxiliary device, which can realize efficient and accurate control of the pipe section track line.

[0043] like Figure 2 and Fig. 9 As shown, the push tooling 2 also includes a stiffener 22, which is connected to the frame 21 to improve the rigidity of the frame 21. Preferably, the stiffener 22 is made of profiled steel. Further preferably, the stiffener 22 is an angle steel with a specification of L100X63X10 or above.

[0044] like Figure 2 and Fig. 9 As shown, the push tooling 2 also includes a reinforcement panel 23, which is arranged on the contact surface between the frame 21 and the tugboat to disperse the force of the frame 21 and prevent the frame 21 from being overloaded and damaged. Preferably, the reinforcement panel 23 is a steel panel. Further preferably, the thickness of the reinforcement panel 23 is 0.12m to 0.15m.

[0045] Preferably, the frame 21 is made of I-beams with specifications of HW200a or above and / or steel pipes with specifications of Φ203×12 or above.

[0046] Further preferably, the base 1 is welded to the submerged barge.

[0047] More preferably, the base 1 includes a base panel 11 , a base side panel 12 , a reinforcing bracket 13 and other components.

[0048] In this embodiment, there are two types of floating assistance devices, namely, a floating assistance device of type A and a floating assistance device of type B. Figure 1 to Figure 7 As shown, it is a floating auxiliary device of type A, which includes a pushing fixture of type A 2 and a base of type A 1. The base of type A is used to fix the pushing fixture of type A 2. The pushing fixture of type A 2 is provided with three mooring piles 211. Figure 8 to Figure 14As shown, it is a B-type floating auxiliary device, which includes a B-type pushing fixture 2 and a B-type base 1. The B-type base 1 is used to fix the B-type pushing fixture 2, and two mooring piles 211 are arranged on the B-type pushing fixture 2. It can be noted that the A-type floating auxiliary device in this embodiment can only apply force to the sinking barge in one direction, and the B-type floating auxiliary device can apply force to the sinking barge in two directions. Each side of each sinking barge is installed with an A-type floating auxiliary device and two B-type floating auxiliary devices, which can ensure that the tugboat can apply force to the sinking barge in two directions, so that the tugboat can control the track line of the sinking barge from two directions, and thus more accurately control the track line of the pipe section.

[0049] It should be noted that the connection position between the frame 21 in the floating auxiliary device in this embodiment and the base 1 welded on the submerged barge and the position of the mooring pile 211 arranged on the frame 21 must be able to ensure that when the tugboat is connected to the submerged barge through the floating auxiliary device, the tugboat's towing force can be evenly and relatively balanced applied to the submerged barge.

[0050] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
