Title of the articleGeotechnical monitoring of the building during the reconstruction of the monument of history and architecture
Abstract.Building of underground constructions of deep foundations, especially in the vicinity of existing structures is a very complex and demanding task. In order to timely detect the influence of underground construction on the state of the surrounding buildings practiced conducting monitoring of the construction process. The article presents an analysis of the monitoring results conducted within 12 months from the start of the underground 4-storey outhouse to the building of the former Shamovskiy hospital in the city of Kazan. On the walls of the existing building have been installed deformation stamps, and the crack width gauges installed. Not less than once a month surveying method determines the level of deformation stamps and estimated readings of the crack width gauges. At the time the research was completed the construction of bored pile barriering designs, developed ground, leaving a soil berms, erected part of a monolithic reinforced concrete frame of the underground 4-storey outhouse. As shown by the results of monitoring, the development of the deformations of the existing building started long before the start of the excavation of the soil in the pit. A significant impact on the surrounding buildings in this in the first place has the technological process of construction works, namely: device bored piles of large diameter when the device of the barriering designs. However, despite this, at the time of the study values of maximum sediment individual sections of an existing building does not exceed the limit values set by regulations.
Keywords.monitoring, deep foundation pit, barriering design, CFA piles, bored piles, spacer system, a soil berm.
