Reverse dismantling device for chimney and dismantling method

Abstract

The invention discloses a reverse dismantling device for a chimney and a dismantling method. The reverse dismantling device for the chimney comprises a first horizontal steel plate belt and a second horizontal steel plate belt, wherein the first horizontal steel plate belt and the second horizontal steel plate belt are arranged around the chimney; the diameter of each steel plate belt can be adjusted according to the different diameters of different sections of the chimney, and a plurality of vertical connecting steel channels and steel brackets are arranged between the two steel plate belts and used for transmitting gravity of the chimney and vertical acting force converted by horizontal force to a hydraulic jack and a buttress; transverse tie rods are arranged at the ends of the steel brackets and used for preventing instability and increasing the bearing capacity; and reliable connection is conducted between the steel brackets and the hydraulic jack as well as the steel brackets andthe buttress, the effects of pressure and pulling force can be borne, and the buttress is fixed to a raft formed by pouring of reinforced concrete. According to the reverse dismantling device for thechimney and the dismantling method, after the chimney portion between the two lower sets of horizontal steel plate belts are cut and moved, the jack is utilized to make a part of the chimney to fall,then cutting is continued, and the steps are repeated until the whole chimney is dismantled.

Description

technical field [0001] The invention relates to the field of building science and technology, in particular to a method for reverse demolition of a chimney. Background technique [0002] In the process of urban transformation, with the relocation of factories and mines from urban areas to remote areas, the original chimneys and other structures are no longer used and need to be demolished. At present, the commonly used demolition methods are blasting demolition or mechanical demolition. Due to the dense buildings around factories and mines in urban areas, directional blasting demolition will pollute the surrounding environment and bring negative effects, so it is generally not suitable for use. When the mechanical demolition method adopts scaffolding to be demolished from the top, it has defects such as low efficiency and high construction risk. Contents of the invention [0003] Aiming at the problems existing in the background technology, in order to overcome the defici...

Problems solved by technology

At present, the commonly used demolition methods are blasting demolition or mechanical demolition. Since the buildings around factories and mines in urban areas are relatively dense, directional blasting demolition will pollute the surrounding environment and bring negative effects, so it is generally not suitable to be used.

When the mechanical demolition method adopts scaffolding to be dismantled from the top, it has disadvantages such as low efficiency and high construction risk
