Ecological Safety of Construction in Single-Industry Town

https://doi.org/10.58224/2618-7183-2023-6-3-59-78
Abstract
Ensuring environmental safety during construction works is an important condition for the sustainable development of single-industry towns. The high rate of urbanization, population growth of single-industry towns and their active construction leads to negative anthropogenic changes in the en-vironment, which negatively affects both the ecology and the life of the population of a single-industry town. In this article the basic factors of the influence of the sphere of construction on the environment are considered, the aspects of providing ecological safety during construction are investigated, the normative-legal base regulating these aspects during construction works is analyzed, and also possible approaches and measures to decrease the negative influence of construction on the environment in monotowns are given.
The article proposes measures to reduce the negative impact on the environment and improve envi-ronmental safety of construction in single-industry towns, such as complementing the existing legisla-tion with stricter standards and requirements to ensure environmental safety during construction work in single-industry towns, development and active implementation of modern environmental materials and technologies, strengthening environmental control mechanisms of the construction sphere in sin-gle-industry towns and raising awareness of business and population. The article was prepared based on the results of research carried out at the expense of budgetary funds under the state assignment of the Financial University.

Bridge construction in cramped urban environments

https://doi.org/10.58224/2618-7183-2023-6-2-47-57
Abstract
This article discusses the specifics of the construction of bridge structures in cramped conditions of dense urban development. The classification of bridge structures and features of each type are given. The main characteristics and weight and size parameters of elements of bridge structures, methods of their erection, transportation and installation are considered. Particular attention is paid to the arrangement of the construction site, transportation of finished products and materials to the construc-tion site, as well as measures to prevent damage to buildings, structures and transport routes adjacent to the construction site, including the railway.
The study considered the project for the implementation of the construction of the Strela overpass in the city of Tyumen. Emphasis was placed on the production of radial prestressed reinforced con-crete beams of span structures in construction conditions. It was decided to manufacture these struc-tures at the work site.
