A method for dismantling the concrete structure of the underground space of the existing rolling line

Abstract

The invention discloses a method for dismantling a concrete structure of an existing rolling line underground space, belonging to the technical field of metallurgical production equipment installation. Provided is a method for dismantling the existing rolling line underground space concrete structure, which can quickly, efficiently and safely dismantle the existing rolling line underground space concrete structure without stopping production. The dismantling method is based on the actual situation of the concrete structure in the underground space to be dismantled, and after determining the bearing support point and the dismantling area in combination with the conditions of the rolling production line to be installed in the subsequent sequence, and then adopting the method according to the on-site hoisting and transportation capacity and the condition of the hoisting space. The wire saw cutting method is used for demolition. During the demolition process, it is only necessary to drill sawing holes and erect corresponding support brackets on the concrete structure of the underground space according to the determined maximum weight, maximum shape and demolition sequence of each concrete block. 2. The concrete structure can be sawed into concrete blocks and transported out of the production site of the existing rolling line through ropes.

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...

AI Technical Summary

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
