REINFORCEMENT BY CEMENT GROUTING METHOD OF THE STRIP FOUNDATIONS IN THE SHOPPING CENTER OF CHELYABINSK
Abstract
In this paper the reasons for structural deformations in the operation of the existing building as
a result of technological errors at the construction of adjacent underground parking are clarified.
Physical and mechanical characteristics of the amended soil to convert its structural properties are
analyzed. We determine the possible methods of strengthening to ensure safe operation of the building.
Necessary technological and design parameters of injection are calculated. We have designed
the project of strengthening brick walls, foundations and soils of the basement in the zone of maximum
development of cracks in the load-bearing structures of this object. Cement grouting of the
building basement has been made under direct control by the authors of the project and this article
as well. Geotechnical monitoring is performed during the works and within the subsequent year of
the building maintenance. As a result of the performed works the stabilization of the settlements of
the soil basement and displacements of the foundation structures has been achieved.
Keywords: survey of the building, foundation strengthening, injection grouting, cement grouting,
geotechnical monitoring.
