Abstract
The object of research is the technology of constructing waterproofing screens of buildings and structures from limestone-shell rock. The paper discusses the causes of the violation of the waterproofing of the underground parts of buildings which are made of limestone-shell rock. The problems of preservation of historical buildings and structures made of limestone-shell rock are revealed on the example of such buildings in Ukraine and Moldova: – Odessa Opera and Ballet Theatre; – House of Stratz; – Brodsk Synagogue; – House of Marazli; – Bilhorod-Dnistrovsk and Bendery Fortresses; – Tower of Winds; – Church of St. Cajetan; – Powder Cellar of the Tiraspol Fortress; – Water Mill; – Church of the Archangel Michael in the village Stroenets and many others. Based on the methods of the mathematical theory of the experiment, a complex of experimental-statistical models has been constructed, the analysis of which allowed to estimate the intensity of capillary absorption of the «waterproofing screen – limestone-shell rock» system depending on the depth of injection, the diameter of the injector and the step of its location. An arrangement of injection holes was proposed and justified to ensure waterproofing of structures, which allows filling the capillary-porous masonry space for 6–12 % more than other schemes. The accepted physical model of the distribution of the injectable composition in the porous structure of limestone-shell rock allowed to analyze the depth, diameter, and injection step, which affect the distribution area of the solution in the structural array. The depth of injection is indeed one of the most important technological characteristics in the construction of an intra-structural waterproofing screen. From a technological point of view, the degree of influence of the injection step on the intensity of capillary moisture transfer is quite high, since it directly affects the amount of active waterproofing composition in the injected thickness, as well as labor costs when performing waterproofing works. The diameter of the borehole does not significantly affect the studied parameter within the selected experimental conditions.
Highlights
At present, there is a tendency for the population to revive an active interest in the history of their region
There is an acute problem of preserving historical buildings and structures, the unsatisfactory condition of which requires measures to save them from damage, which is clearly evidenced by nume rous cracks, collapsed structures, or even destruction of unique structures
Studies devoted to the search for optimal technological solutions for the construction of waterproofing screens for buildings made of limestone-shell rock are relevant
Summary
There is a tendency for the population to revive an active interest in the history of their region. When choosing the type of waterproofing, it is necessary to determine its compliance with the requirements, taking into account the specifics and condition of a particular object, hydrogeological conditions, the depth of underground structures, the impact of environmental changes. After these actions, the composition of the adopted waterproofing is determined (number of layers, thickness) [1]. Studies devoted to the search for optimal technological solutions for the construction of waterproofing screens for buildings made of limestone-shell rock are relevant. The object of research is the technology of constructing waterproofing screens of buildings and structures from limestone-shell rock. The aim of research is to conduct a study of the effectiveness of injection technology when installing waterproofing screens, depending on the following factors: injection depth (x1); hole diameter (x2); injection step (x3)
