Efficient method of eliminating accidental damage of sewer tunnel

Abstract

The article is devoted to the development of technological and organizational solutions for elimination of local emergency damage to sewage tunnel collectors. In the article, conditions of operation and constructions of the sewage tunnel collector destroyed by corrosion are investigated on Grekovska street in Kharkiv, Ukraine; the methods of production of repair and restoration works are analyzed in this article; technological and organizational solutions have been developed for the liquidation of emergency damage to sewage tunnel collectors, taking into account technical, organizational and economic indicators. Thus, when comparing recovery options by different methods, it is noted that the proposed technology is more economically feasible in view of the relatively low cost of the material for this solutions. At the same time, the duration of the work by the proposed method of extrusion by introducing a secondary lining with anticorrosive properties will be reduced by 30%.
