Embodiment 1
[0029] Embodiment 1, as attached figure 1 Shown, be used to build the channel type dock of 10,000-ton ship, its length is 400m, the height of the dock wall 1 on left and right sides is 16m, and several hoisting equipments are installed above.
[0030] The slope of dock bottom 2 is 1:18, and the elevation of dock mouth 3 is 1m higher than the local average high tide level. Rubber dams can be installed at dock mouth 3 with a height of 5m, which can block the invasion of extreme high tides and storm surges.
[0031] The dock stern 4 leads to the manufacturing site of the ship section, and the passage of the manufacturing site and the dock bottom 2 are connected with a transition section with a gradient gradient, so that the ship segment and materials can be transported into the dock very conveniently.
[0032] The ramp 5 in front of the dock 3 has a slope of 1:8 and a length of 40m, leading to the sea. The dock bottom 2 and the ramp 5 are connected by a transition section with a...
Embodiment 2
[0035] Embodiment 2, as attached figure 2 As shown, the passageway dock for building 100,000-ton ships is an embedded structure excavated according to the terrain, and its length is 1000m.
[0036] The height of the front end of the dock wall 1 on the left and right sides is 25m, the track of the lifting equipment is set on the dock wall, and several lifting equipment are installed above, and the tail of the dock wall can be connected with the track beam and the track of the gantry crane.
[0037] The slope of the dock bottom 2 is 1:200, and the elevation of the dock mouth 3 is the local high tide level. A detachable dam can be installed at the dock mouth 3, with a height of 4m, which can block the invasion of extreme high tides and storm surges.
[0038] Heavy rails are laid on the bottom of the dock 2 and the ramp 5, and the tail of the dock 4 leads to the factory building of the ship section. The passage of the factory building is connected with the bottom of the dock 2. ...

Abstract
The invention relates to a dock for repairing and manufacturing ships, comprising dock walls at the left side and the right side and a dock floor; a ramp leading to water area is arranged at the frontof a dock entrance; and a dock tail leads to a road or a working place. In the invention, altitude of the dock entrance of the channel dock is higher than mean high tide, and investment on building alarge dock gate is not required, thus a large number of investment and use cost are saved. The channel dock is suitable for manufacturing ships in various scales from ten tonnage level to ten thousand tonnage level, the dock can be manufactured to be long to form a dock production line, the dock tail has no rear dock wall and can be extended into a workshop and a plant, the dock wall thereof canbe connected with a track beam of a portal crane so as to segment the ship and directly transport the segmented ship with materials into the dock by land. The ship launching or upgrading of the channel dock is finished by relying on a track pulley or an airbag.
Description
technical field [0001] The invention relates to a dock for repairing and building ships, which belongs to the technical field of ship manufacturing. Background technique [0002] With the vigorous development of the shipping industry, the scale of shipbuilding has become larger and larger, and large ships are generally manufactured and repaired in docks. These docks are generally composed of three dock walls and dock doors. Such large docks require a huge investment scale and a long construction period. In order to improve the production efficiency of the dock, many shipyards adopt the process of assembling ships in sections. The sections of the ship are transported from the processing site to the floating platform or barge, and then sent to the dock by water. After two transfers, the whole process is very Complicated, difficult and inefficient. The cost of using the dock is also quite high. Due to many unstable factors in economic development, the investment risk of this...
