Ensuring the stability of the deep pit enclosure and foundation bases in the conditions of reconstruction of the architectural monument in the city of Kazan

Abstract

Technical solutions for the reconstruction of the building of the Shamovskaya Hospital, an architectural monument built in 1907-1910, are highlighted in Kazan. The reconstruction involves the construction of a 4- storey underground extension to the building. The implementation of the developed architectural solutions revealed a number of problems associated with ensuring the stability of the foundation when developing a deep pit in the immediate (0.5 m) proximity to the building. The authors propose technical solutions to strengthen the foundations of the existing building of the Shamovskaya Hospital, as well as the structure of the retaining wall.
