Abstract

The invention relates to a foundation construction method of large equipment, especially a construction method for split burying of a large T-shaped sleeve bolt, comprising the following steps: setting embedded iron parts on a bedding layer; mounting blot fixing frames above the embedded iron parts; after determining central control point positions of the bolts, welding anchor plates on the blot fixing frames; welding anchor boxes at the bottom of the anchor plates; rechecking the positions of the anchor plates and the anchor boxes, and then hoisting bolt sleeves; exactly assembling the bolt sleeves and the anchor plates, then welding and fixing; hoisting T-shaped bolt rods, fixing the T-shaped heads of the T-shaped bolt rods and the anchor plates by bolts, welding top covers of the sleeves on the upper parts, cleaning sundries surrounding the bolts, checking the welding quality, and rechecking the positions of the bolts. Compared with the traditional hoisting method, the method in the invention can reduce kinds and amounts of approach engineering machines, and can reduce constructors so as to improve working efficiency, reduce construction cost, reduce environment pollution and noise pollution, guarantee green construction and meet the national requirements of energy conservation and emission reduction.

Description

technical field

[0001] The invention relates to a large-scale equipment foundation construction method, in particular to a large-scale T-shaped sleeve bolt split-buried construction method. Background technique

[0002] Large-scale equipment foundation is the most important thing in industrial buildings. It is very common to use T-shaped sleeve bolts. Its characteristics include: a large number of pre-embedded bolt sleeves, large bolt diameters, and difficult processing and on-site installation. These characteristics have brought great construction difficulties to the foundation construction of large-scale steel rolling core equipment. At present, there are many kinds of buried construction technologies to improve the accuracy accordingly, such as using H-shaped steel, I-beam, channel steel, angle steel, or using fixed models, etc., but they all belong to the overall hoisting installation. In these construction technologies, all Reasonable use of machinery is not considered...
