Detaching method for existing rolling line underground space concrete structure

Abstract

The invention discloses a detaching method for an existing rolling line underground space concrete structure and belongs to the technical field of metallurgy production device installing. By means of the method, the existing rolling line underground space concrete structure can be detached fast, efficiently and safely under the condition that production is not stopped. According to actual conditions of the underground space concrete structure required to be detached, by combining conditions of a rolling production line required to be installed at a later procedure, a load bearing supporting point and a detaching area are determined, and detaching is conducted by using a rope saw cutting method according to conditions of field hoisting, transportation capacity and hoisting space. In a detaching process, according to determined maximum weight, largest shape and detaching sequence of each concrete block, saw cutting holes are drilled in the underground space concrete structure, corresponding supporting frames are erected, ropes penetrate the holes, and the concrete structure is saw cut into concrete blocks to be transported out of an existing rolling line production field.

Description

technical field [0001] The invention relates to a dismantling method, in particular to a dismantling method of a concrete structure in an underground space of an existing rolling line, and belongs to the technical field of metallurgical production equipment installation. Background technique [0002] The concrete structure of the underground space of the existing rolling line is very complex, involving many complex structures such as beam-slab forms, columns, shear walls, line trenches, equipment foundations, etc., and there are many inconveniences in online demolition. Existing common demolition methods are to adopt methods such as blasting and pneumatic picks to carry out destructive demolition after the production line is shut down. Because the described destructive demolition method not only has high demolition cost and great potential safety hazards in the demolition process, but also has extremely low demolition efficiency, and cannot meet the practical requirements of...

Problems solved by technology

Because the destructive demolition method described not only has high demolition cost and great potential safety hazards in the demolition process, but also has extremely low demolition efficiency, and cannot meet the practical requirements of quickness, safety and efficiency.

Especially when it is necessary to ensure the normal operation of various facilities in the workshop, ensure the safe production of the rolling line, and start the online installation and construction of the new rolling mill as soon as possible after removing the reinforced concrete underground space structure of the existing rolling line Realistic requirements are even more unsatisfactory
