Pipe gallery module deck hoisting method

Abstract

The invention provides a pipe gallery module deck hoisting method, and belongs to the technical field of construction of pipe gallery modules. The method comprises the following steps: arranging six large hoisting points on a pipe gallery module deck, and selecting a first crawler, a second crawler as well as a lower trolley and an upper trolley of a gantry crane to hoist the six large hoisting points; connecting the lower trolley of the gantry crane with the two large hoisting points through a first hoisting rod, and connecting the upper trolley and the lower trolley of the gantry crane with the two large hoisting points through a second hoisting rod; connecting a first hoisting arm of the first crawler with one large hoisting point through a first hoisting hook; connecting the lower portion of a second hoisting arm of the second crawler with one large hoisting point through a second hoisting hook; slowly hoisting the pipe gallery module deck away from a jig frame through the lower trolley, the upper trolley, the first crawler and the second crawler; and driving the pipe gallery module deck to slowly move towards a to-be-combined module deck and lowering the pipe gallery module deck to the correct position on the to-be-combined module deck so as to complete hoisting. According to the method, one-time hoisting of the pipe gallery module deck with the ultra-large size can be realized, and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of pipe gallery module construction, and relates to a method for hoisting a pipe gallery module deck. Background technique [0002] The pipe gallery module is a complex steel structure used to arrange a large number of pipe systems in the land chemical plant construction project, mainly composed of columns, beams, diagonal braces, etc. The decks are distributed according to different heights, and various piping systems, equipment, cables, etc. are arranged on them. The large-scale modular pipe gallery has the characteristics of large size, heavy weight, high height and large structural span. [0003] The traditional construction method divides a single pipe gallery module deck into several small decks and builds them separately. Due to the large number of decks, the number of hoistings is large, the hoisting cycle is long, and the dimensional accuracy of the docking position is not easy to control. [0004...

Problems solved by technology

[0003]The traditional construction method divides a single pipe gallery module deck into several small deck pieces to be built separately. The cycle time is long, and the dimensional accuracy of the docking position is not easy to control

[0004]Due to the large size, heavy weight and weak rigidity of a single pipe gallery module deck, and the limitation of hoisting equipment and methods, it is extremely difficult to hoist as a whole by traditional hoisting methods
