Method for integrally sliding and installing a steel vestibule in a complex environment

Abstract

The invention discloses a method for integrally sliding and installing a steel vestibule in a complex environment. The method comprises the following operation steps: (1), installing sliding supports at the bottoms of front, rear, left and right stand columns of a newly-built vestibule; (2), erecting a mounting platform above the originally-built vestibule which obstructs the mounting of the newly-built vestibule; (3), welding an operating platform at the rear end of the mounting platform, and arranging a chain block on the operating platform; (4), hoisting the newly-built vestibule to the front part of the mounting platform by using a common crane at the front end of the mounting platform; and (5), pulling the newly-built vestibule backwards to be in place through dragging of a chain block of the chain block and sliding of the sliding support on the mounting platform. A traditional vestibule installation method is changed, the construction period of overall installation of the newly-built vestibule is shortened, an oversized crane is prevented from being used in construction, the construction difficulty is reduced, and the cost is saved.

Description

technical field [0001] The invention relates to a steel structure engineering construction technology, in particular to an overall sliding installation method for a steel corridor in a complex environment. Background technique [0002] In the field of raw material transportation in the metallurgical industry, in order to expand production capacity, many enterprises need to transform the original production system. Due to the limitation of many site obstacles, it is necessary to build new transfer stations and steel structure corridors in the original production area. [0003] The environment of the existing construction site is complex. For example, the engineering corridor needs to be built above the original steel structure corridor. The hoisting height is large and the distance is long. The traditional construction method is to divide the corridor into pieces or use a super large crane for overall hoisting , The bulk construction period of the corridor is long, which cann...

Problems solved by technology

[0003]The existing construction site environment is complicated. For example, the engineering corridor needs to be built above the original steel structure corridor, the hoisting height is large and the distance is long. The traditional construction method is to The passageway is divided into pieces or hoisted as a whole with a super-large crane. The construction period of the passageway in bulk is long and cannot meet the time requirements for on-site renovation. However, the overall hoisting of the passageway with a super-large crane is too expensive and uneconomical
