Method for removing reinforced concrete chimney

Abstract

The invention discloses a method for removing a reinforced concrete chimney. The method for removing the reinforced concrete chimney comprises the following steps of: I, performing buffer layer laying: laying a buffer layer at the toppling position of the reinforced concrete chimney; II, performing guide steel cable installation: laying a guide steel cable for guiding the chimney during a toppling process; III, performing chimney outer side packaging and water spray pipeline laying; IV, performing cutting area marking; V, performing temporary support member installation; VI, performing cutting area concrete chiseling away and steel bar cutting off; VII, performing water spraying; VIII, performing adjustment on the support height of a temporary support member until the chimney is toppled: gradually adjusting the support height of the temporary support member downwards until the chimney is unstable under the effect of the gravity of the chimney and is toppled onto the buffer layer; and IX, clearing a construction site. The method disclosed by the invention is simple in step, reasonable in design, convenient in implementation, high in removal speed and good in using effect. The chimney is entirely, slowly and directionally toppled by utilizing the temporary support effect of the support member, and the construction problem that the reinforced concrete chimney is entirely and rapidly removed under a non-blasting operation condition is solved.

Description

technical field [0001] The invention belongs to the technical field of dismantling construction of engineering structures, and in particular relates to a method for dismantling a reinforced concrete chimney. Background technique [0002] The demolition of reinforced concrete chimneys is a common construction content in municipal engineering construction. Nowadays, the commonly used demolition construction methods are divided into the following two types: one construction method is the demolition method of manually breaking the concrete from top to bottom, and the other construction The method is the overall directional blasting demolition method. However, in actual construction, the above-mentioned first construction method has defects such as long time for high-altitude operations, time-consuming and labor-intensive work, etc., not only high construction costs, but also high safety risks for high-altitude operations; The instantaneous collapse speed is very fast, the impac...
