Construction method for hoisting engineering tube well stand pipe of high-rise building

Abstract

The invention discloses a construction method for hoisting an engineering tube well stand pipe of a high-rise building. The construction method includes: (1) construction is prepared; (2) a main lifting hoist and an auxiliary hoist are set; (3) a pipeline is conveyed to a tube well portion horizontally; (4) the section of the pipeline at the topmost end of the stand pipe is hoisted through the main lifting hoist; (5) the reciprocal second section of the pipeline of the stand pipe is hoisted through the auxiliary hoist; (6) the two pipelines are aligned and connected through bolts; (7) the main lifting hoist hoists the two connected pipelines to a certain height, the auxiliary hoist hoists the reciprocal third section of the pipeline of the stand pipe to the height the same as that of the two connected pipelines, and the third section pipeline is connected with the two sections of pipelines; (8) the whole stand pipe is hoisted to an installation position for support fixing; (9) after one stand pipe is constructed, the other stand pipes are sequentially hoisted; and (10) the steps are performed until the whole stand pipe is connected. The construction method for hoisting the engineering tube well stand pipe of the high-rise building is easy and convenient to operate, fast and efficient and convenient to use, reduces the cost, and improves the efficiency.

Description

technical field [0001] The invention relates to a construction method for hoisting pipe well standpipes in high-rise building engineering, in particular to a construction method using pipe inversion. Background technique [0002] According to the hoisting of the air duct well standpipes of super high-rise buildings, the traditional "formal installation method" is usually used for the construction of the duct well riser pipes. The construction sequence is connected and installed one by one from the bottom to the top. At the pipe well, this method requires multiple vertical and horizontal transportation of the air pipe, which has low construction efficiency and great safety hazards. In addition, it is difficult to align the upper and lower air pipes and maintain verticality during the butt joint construction between the risers. For tube wells with narrow spaces, the construction is difficult and the quality is difficult to guarantee. Contents of the invention [0003] The t...
