Method for building bridge crossing ladder of marine engine room

Abstract

The invention provides a method for building a bridge crossing ladder of a marine engine room. The method comprises the following steps: forming a through room process hole in an outer board of the marine engine room; after the through room process hole is formed, hoisting a marine engine room total section, in which the through room process hole is formed, into a dock, so as to finish carrying; and building the bridge crossing ladder between the through room process hole and a dock wall gallery. By utilizing the method provided by the technical scheme of the invention, the layout of pipelinesin the room is relatively convenient and reasonable, so that the construction environment is effectively improved, and meanwhile, the field 6S management is facilitated; by forming the through room process hole, the construction is relatively convenient, so that the working efficiency is improved; a route for constructors to enter the room is changed into a straight line, and the ship boarding route is effectively reduced, so that the constructors can conveniently board a ship, and the ship boarding labor hour is effectively shortened; and meanwhile, the bridge crossing ladder can be taken asa fire safety channel, and the constructors can conveniently evacuate in dangerous situations, so that the life and property safeties of the constructors are guaranteed.

Description

technical field [0001] The invention relates to the technical field of ship building technology, in particular to a method for erecting a ship engine room bridge ladder. Background technique [0002] With the development of modern technology, the shipbuilding industry is developing more and more high-end. The original small wooden boat has developed into a 10,000-ton steel ship. When the ship is built in the dock, the engine room area is equipped to form a wall structure. The air pipes and gas lines in the area all pass through the main deck, resulting in chaotic pipeline layout. In the engine room, there are many cross-cutting operations of various types of work, a large number of construction personnel, and poor overall construction conditions, which seriously affect the construction quality and progress of each operation. The construction workers inside generally need to enter the engine room through the erected bridge ladder to carry out operations. [0003] In the prio...

AI Technical Summary

Problems solved by technology

The entire route for construction personnel to enter the engine room is tortuous, and it is very inconvenient for construction personnel to board the ship and wastes a lot of man-hours. It will be more difficult for construction personnel to enter the engine room when they are holding heavy equipment such as air ducts and welding machines. In the event of a safety accident in the engine room, the above-mentioned route makes it inconvenient for construction workers to evacuate and poses a safety hazard

In addition, during the construction in the engine room, the air pipes and gas lines in this area pass through the main deck, resulting in chaotic pipeline layout, which is not conducive to on-site 6S management
