HIGH PERFORMANCE TECHNOLOGIES FOR LIQUIDATION OF NON-OPERATIONAL PRODUCTION FACILITIES

The paper analyzes main reasons that have led to closure of a number of industrial enterprises on the territory of the Republic of Belarus and in the majority of former Soviet Union countries. An analysis of constructive decisions and range of bearing and enclosing structures for non-operational industrial buildings and facilities has been carried out in the paper. The analysis has made it possible to draw a conclusion that the overwhelming majority of the buildings and facilities were constructed using prefabricated and cast-in-situ reinforced concrete structures. Taking into account the facts that substantially all non-operational industrial buildings and facilities are located in industrial zones being rather far from residential housing area and having developed infrastructure (highways, railway lines, communication network etc.) and expenses on infrastructure development usually exceed the cost of newly built industrial buildings and facilities some findings have been given on expediency pertaining to usage of existing industrial zones. The main problem has been defined in the paper and its solution will permit to use again existing industrial zones with non-operational industrial facilities which are located there. With due account for the executed analysis of standard operating procedures on liquidation of industrial buildings an expediency has been revealed that presupposes demolition of facilities with the help of mechanical breakdown. An economic efficiency on application of mechanical demolition method for industrial buildings constructed using prefabricated and cast-in-situ structures has been illustrated in Work Execution Plan on liquidation of industrial buildings in the workshop which has been involved in lime production at JSC “Berezovsky Industrial Complex of Silicate Products”. The proposed technology for mechanical demolition of reinforced concrete structures is based on application of a caterpillar excavating machine of Doosan S340LC-VSDM model. Its application permits to ensure complete safety conditions while executing works.
