Embodiment Construction
[0042] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings. The hoisting construction method adopts the hoisting method of row-by-row and block-by-block, and two sets (eight groups of 100 tons) of hydraulic lifting devices are installed to implement the hoisting work of each row of modules. Each column of modules is completed by top-down, block-by-block docking, flip-chip assembly, and one-time positioning; the first column is lifted at the original position, and the second column is in the direction of the center to the left (third column) of the furnace After the position of displacement s1 is hoisted to the in-place height, it is then translated into place. When in place, the elevation of the base is increased by the compensation amount h1. The second row is a higher than the first row; the third row is hoisted at the position where its center is shifted to the left direction of the furnace by s2...

A vertical type waste heat boiler module hanging construction method is used for completing hanging construction of more than two rows of waste heat boilers, and each row comprises 1-4 waste heat boilers. The method comprises the steps that construction preparation is carried out; a lifting device is arranged; a I-1 module is hung; a I-1 module packaging object is detached; the I-1 module is connected with a lower anchor head base; the I-1 module is lifted; a II-2 module and the I-1 module are connected in an abutting mode, and the II-2 module is lifted; the above steps are repeated, and hanging of the rest of the modules in the first row is completed; the lifting device is subjected to row changing, the above steps are repeated, and hanging of the rest of rows of modules is completed; and the lifting device is detached, and a construction site is cleared. The method has the advantages that a row-dividing block-by-block hanging method different from a traditional lifting method is used, and hanging equipment investment is saved; a loxic hydraulic lifting system is used for lifting and being in position, and safety and reliability are achieved; and single-row module lifting is used, and operation is convenient.
Description
technical field [0001] The invention relates to the technical field of engineering construction, in particular to a construction method for hoisting vertical waste heat boiler modules. Background technique [0002] As a vertical, triple-pressure reheating, natural circulation waste heat boiler, the boiler is used to generate high, medium and low pressure steam and reheat steam, and is arranged in the open air. The supplier adopts modular design for the heating surface of the waste heat boiler. The heating surface module of each boiler is divided into three columns with 12 modules in total. Each column is composed of 1-4 modules vertically. The total weight of each column is It is 563800kg, the structural size of the waste heat boiler is 41.5m×17m, and the elevation of the center line of the high-pressure steam drum is about 39.2m. The elevation of the chimney top is 65m, the diameter is 5.91m, and it is arranged on the top of the furnace. The steel frame of the boiler is w...
