AbstractAbout AuthorsReferences
The paper studies the trenchless installation of pipes by microtunneling method under a curtain wall (section between towers) between Setunskaya and Zatrapeznaya towers of the Novodevichy monastery – the architecture monument of Federal significance. Design of utilities reconstruction at the historical and architectural ensemble’s site was done under scientific supervision. Scientific supervision was provided by the laboratory «Soil bases, foundations and underground structures» of the Scientific-Research Institute of Building Physics of the Russian Academy of Architecture and Construction Sciences. Installation works on the utilities were conducted in difficult geological and hydrogeological conditions, characterized by the presence of anthropogenic soils, soft water saturated soils – fine sands, also of loose density, and a high ground water level. The technology of microtunneling works is described. A general layout of the AVN 500 shield is given which was used for the rainwater pipes installation under the monastery’s curtain wall. The article analyzes the results of determining the soil overcut VL during microtunneling according to the formula recommended by SP 249.1325800.2016 «Underground utilities» for preliminary assessment of the VL value, by the empirical method, as well as from observation data of the curtain wall structure after the end of a shield boring. The article demonstrates that the installation of utilities by microtunneling on cultural heritage sites ensures their preservation.
