Embodiment 1

[0016] This dock pier method includes the following steps:

[0017] a. Baseline setting and deck leveling: first draw a straight line on the opposite ends of the dock deck as the horizontal baseline, and then fill the concave part of the deck to the horizontal baseline to make the deck surface smooth;

[0018] b. Building the mid-dragon plinth: on the flat deck surface along the horizontal base line, densely support the mid-dragon pier corresponding to the center keel of the ship in sequence, and make the middle mid-draft pier above the center of the dock;

[0019] c. Build side piers: On the deck surface, build side piers according to the rib position of the ship on both sides of the middle dragon piers. The included angle with the horizontal plane is 15°;

[0020] After the base is built in step d and c, the sandbags that play a buffering role for the ship pier are laid on the upper end faces of the middle dragon pier seat and the side pier seat;

[0021] e. After the base...

Embodiment 2

[0024] The angle between the upper end surface of the side pier seat and the horizontal plane is 20°; the rest are the same as in Embodiment 1.

Abstract

The invention discloses a method for pilling up a pier for a dock, and belongs to the technical field of manufacturing of ships. The method comprises the following steps: a, flatting a deck: drawing a straight line from two opposite sides of a dock deck and taking the straight line as a horizontal base line, filling a recess of the deck to the horizontal base line, and flatting the surface of the deck; b, piling up middle pier bases, arranging a plurality of middle pier bases for supporting corresponding parts of a middle keel of a ship along the horizontal base line on the flatted surface of the deck, wherein one of the middle pier bases is above the center of the dock; and c, pilling up edge pier bases: pilling up edge pier bases on the two sides of the middle pier bases on the surface of the deck, wherein the upper end face of each the edge pier base is inclined and the angle between the upper end face of each edge pier base and the horizontal plane is alpha. By the method, the problems that the difficulty and the risk are high, and beaching is not stable, so that the ship is easy to deform locally in the process of mounting a pier for a V-bottom ship are solved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for building docks. Background technique [0002] In the shipbuilding industry, ships that have been produced or sailed for a certain period of time need to be tested for various performances. Before the ship is tested, it needs to be seated on the dock first, so it is necessary to build a pier for the ship on the dock; the existing The dock pier method is: place pier blocks on the dock corresponding to the bottom of the hull. This method of beaching exists: because the center of gravity of the sharp-bottomed ship is relatively high, it is difficult and The risk is high, and the beach is not stable, which may easily lead to local deformation of the ship. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for building pier in dock, which can solve the difficulty and high risk in the process of buil...
