PERFORMING SAFELY AND EFFICIENTLY THE DEMOLITION OF A WATER COOLING TOWER BY USING BLASTING WORKS
Abstract
At the present stage of greening of the old productive units, the demolition process using blasting works have an increasing application due to the reduced time consumption, labor and expenses. A large number of demolition works by using explosives and characterized by a high degree of difficulty, have shown that the use of the blasting technique is a proper alternative from the point of view of efficiency, quality and security. Each construction creates a special case, the calculation of the blasting parameters are adapted according to each specific situation. Basting parameters and explosive charges are dimensioned according to the type of material and section of the construction elements to be sectioned. The most commonly used method of demolition is the collapse of the construction itself or its overturning in a given direction. For this purpose, numerous works of structural preparation, removal or reduction of the section of constructive elements are made beforehand. This article describes the practical way of realizing the demolition of a water cooling tower located in the immediate vicinity of a railway line, using the computer simulation of the structure preparation works according to the chosen demolition concept, so that the blasting and demolition works are executed in efficiency and security conditions.
