Abstract
Full-scale study and justification of the parameters of injection of mortar during cementation of the foundation of the Gymnasium building No. 45 in Rostov-on-Don
Incoming article date: 09.05.2023The article describes the conduct of field studies carried out during the overhaul of the cultural heritage object – the building of MBOU "Gymnasium No. 45" to establish rational parameters of injection of cement-sand mortar, the choice of the type and design of injectors and the scheme of drilling injection wells. It is proved that the technical solutions adopted in the soil fixing project are not optimal and do not provide the required quality of work. Recommendations on technological and constructive solutions for fixing soils have been developed and implemented in practice, taking into account engineering and geological conditions, the results of the survey and fixing at the pilot site.
