Description

Technical Field

[0001] The invention relates to the field of modification and repair of a special-shaped pontoon type floating dock at a pier, and in particular to a berthing method of a special-shaped pontoon type floating dock. Background Art

[0002] At present, in the process of widening and reconstructing the floating dock, since the newly widened pontoon adopts a trapezoidal structure, the overall form of the pontoon of the floating dock changes from a rectangle to a special-shaped form after widening. When the dock is widened and reconstructed, the newly added pontoon structure is added, and at the same time, it is affected by the daily ebb and flow of the tide. During a certain period of the day, when the tide of the floating dock increases, the berthing pad placed between the floating dock and the dock cannot play a berthing role, and the floating dock is at risk of bumping against the dock. In order to ensure that the berthing pad needs to always play a buffering role between the floating dock and the dock during the modification of the floating dock, and eliminate the risk of collision between the floating dock and the dock, a berthing method for a floating dock with a special-shaped pontoon type is needed to solve this problem. Summary of the invention

[0003] The purpose of the present invention is to provide a method for berthing a special-shaped pontoon-type floating dock.

[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a method for berthing a special-shaped pontoon type floating dock, comprising the following steps: a. Fabrication of berthing bulwark structure; b. Erecting scaffolding on the reverse side of the berthing bulwark structure; c. Install berthing bulwark structures on the special-shaped pontoons at two locations on one side of the floating dock and at a certain distance from the bow and stern; d. When the floating dock is berthing at the wharf, a rubber fender is placed at the berthing bulwark structure; e. Use the fender fixing cable to fix the rubber fender relatively to the dock, and the other end of the fender fixing cable is wrapped around the mooring pile of the dock; f. After the floating dock modification is completed, a counterweight for adjusting the center of gravity is installed on the smooth surface of the berthing bulwark structure, and two removal lugs are installed on the upper part of the berthing bulwark structure; g. Use wire rope to connect the dock crane to the two removal lugs on the berthing bulwark structure, enter the tooling scaffolding on the opposite side of the berthing bulwark structure, cut off the part connected to the floating dock, and after the dock crane is tightened, remove the berthing bulwark structure to complete the berthing of the special-shaped pontoon-type floating dock.

[0005] In the step c, a berthing bulwark structure is installed on the special-shaped pontoons at two positions on one side of the floating dock and at a distance of 30-40m from the bow and stern respectively.

[0006] In the step d, the diameter of the rubber fender is ≥3.5m.

[0007] In steps f and g, the removal lifting lug is a 20-ton lifting lug.

[0008] The present invention discloses a berthing method for a special-shaped pontoon-type floating dock, which solves the problem of the special-shaped pontoon-type floating dock docking at a pier. The method is not affected by tidal changes, and ensures that the fender between the floating dock and the pier always plays a protective role. At the same time, there is no need to change the form of the rubber fender, and the risk of the floating dock colliding with the pier during the modification of the floating dock can be completely eliminated.

[0017] like Figures 1 to 7As shown, the berthing method of the special-shaped pontoon type floating dock includes the following steps: a. making a berthing bulwark structure 3; b. setting up a tooling scaffolding 7 on the back of the bulwark structure 3 in advance before installing the berthing bulwark structure 3; c. installing the berthing bulwark structure 3 on the special-shaped pontoons 6 at two positions on one side of the floating dock and 30-40m away from the bow and stern respectively; d. When the floating dock is berthing at the pier 1, a rubber fender 2 with a diameter of ≥3.5m is placed at the berthing bulwark structure 3; e. The rubber fender 2 is relatively fixed to the pier 1 using a fender fixing cable 4 with a diameter of ≥40mm, and the other end of the fender fixing cable 4 is wound around the mooring pile 5 of the pier 1; f. After the floating dock is modified, a counterweight 8 for adjusting the center of gravity is installed on the smooth surface of the berthing bulwark structure 3, and two 20-ton removal lifting lugs 9 are installed on the upper part of the berthing bulwark structure 3; g. With the cooperation of the dock crane 10, a steel wire rope 11 is used to connect the dock crane 10 with the two 20-ton removal lifting lugs on the berthing bulwark structure 3. The ear 9 is connected, and the worker enters the tooling scaffolding 7 on the back side of the berthing bulwark structure 3, cuts off the connection part with the floating dock, and after the dock hoist is tightened, the berthing bulwark structure 3 is dismantled to complete the berthing of the special-shaped pontoon type floating dock; the berthing method of the special-shaped pontoon type floating dock of the present invention successfully solves the problem of the collision between the floating dock and the dock during the berthing of the special-shaped pontoon type floating dock. This method is not affected by the change of tide, and ensures that the rubber fender between the floating dock and the dock always plays a protective role. At the same time, there is no need to change the form of the rubber fender, which meets the needs of the special-shaped pontoon type floating dock berthing at the dock.
