| Title of the article | Prevention of collapse of pit and trench walls in cramped conditions of built-up areas |
| Abstract. | The experience of construction of new buildings and repair and restoration works in the conditions of dense urban development allows ensuring the safety of work performance of the underground part of buildings on the historically established territories. The purpose of this research is to study design and technological solutions to prevent the collapse of the walls of pits and trenches for foundations of various depths in cramped urban conditions. The following tasks were solved to achieve this goal: 1. The information and analytical review of design solutions for construction, repair and reconstruction projects in cramped urban conditions was carried out. 2. The review of modern experience in the organization and technology of zero-cycle work during the construction and renovation of buildings in cramped urban conditions was carried out. 3. The review of design solutions and regulatory requirements to ensure the stability of the walls of trenches and pits was completed. Results. The performed review of new construction sites with a simultaneous reconstruction of existing buildings of urban development allows stating that a full survey, as well as the qualitative design and construction of underground and above-ground parts of buildings is a guarantee of safe implementation of construction and erection works. Conclusions. The safety of the object of construction and repair in the cramped conditions of dense urban building is linked to the preservation of serviceable condition of all existing buildings on the territory under development, as well as the avoidance of dangerous situations at each stage of construction of new facilities. At the same time, it is necessary to take into account the limited possibility of deployment of the necessary size of the construction site in comparison with the unconstrained conditions determined by the regulatory requirements for new construction. The analyzed structural solutions of trench and excavation wall supports ensure compliance with the safety requirements at the construction site. At the same time, during the development and backfilling of shallow excavations, it is required to observe the requirements of safe work performance. The individual schemes of structures for strengthening vertical walls of trenches and pits considered by the authors in various combinations make it possible to perform new combinatorial schemes of fastening, the execution of which is focused on the use of traditional and modern lightweight building materials and products. |
