GEODETIC RESEARCH OF THE SMOKESTACK TILT OF THE BOILER HOUSE ON KARNAUKHOVA STREET IN RIVNE

Abstract

Smokestackеs are extraordinary and technologically important construction structures. Their safe operation is a prerequisite for long-term and trouble-free operation of a boiler house and the provision of heat to entire city districts. The purpose of this paper is to study the smokestack tilt of a boiler house using geodetic methods. The relevance of this research is in the fact that the smokestack tilt a dangerous factor that can lead to its destruction due to loss of stability or due to the force exceeding the maximum resistance. The destruction of such a structure can cause significant economic or even human losses.
 A preliminary calculation of the accuracy of geodetic work to determine the smokestack's tilt on M. Karnaukhova Street was performed. Based on the calculation results, an electronic total station Leica TCR 1205 was selected. A modified coordinate method was used to determine the position of a large number of points on the outer surface of the smokestack for each horizontal section. The measurement results are balanced by the parametric method of the least squares method. This method is implemented in the "Kren" software module developed by the authors.
 Three measurement cycles were performed in 2021, 2022, and 2023. The value of the tilt (about 200 mm) is quite noticeable for this smokestack with a bottom section diameter of 3.65 m. The smokestack is tilted in the direction from which the mobile communication equipment is installed. The balanced tilt value differs from the value calculated from the outermost observation points from the station. Tilt monitoring data should be considered as an integral part of the chimney building information system (BIM).
