ОПРЕДЕЛЕНИЕ УВЕЛИЧЕНИЯ ДЕРЖАЩЕЙ СИЛЫ СВАЙНОЙ РУСЛОВОЙ ОПОРЫ ЗА СЧЕТ ИСПОЛЬЗОВАНИЯ ЗАБИВНОГО ЯКОРЯ

Abstract

The forest industry in the Russian Federation is actively developing. At the same time, technological and production equipment is being modernized, and timber supply chains are being optimized. A large number of timber industry enterprises have increased the volume of transportation of round timber by water modes of transport, in particular, in rafts in the North-West Federal District of the Russian Federation in recent years. Pile piers are used to prevent "drying" of rafts and fastening of forest transport units in a riverbed. In the case when the enterprise’s raid is at the mouth of the river, the pile pier is subjected to additional loads due to freezing of ice and fluctuation of the water level in the river as a result of tidal phenomena in the spring-winter period. ВAs a result, pile pier is dismantled by ice. It leads to the annual replacement of pile dolphins in spring after passing the ice drift. According to the authors, this is not economically profitable, as it forces enterprises to spend annually labor and material resources on the manufacture and installation of pile channel piers. However, their installation should be carried out in a short time. When studying the state of the issue, a pile pier with an increased holding force has been selected, which is additionally equipped with a holding device in the form of a driven anchor. The paper presents the results of a study of the state of the question under study, the research methodology, analysis of experimental data and the obtained mathematical dependencies. The obtained experimental data and dependences have been processed by standard statistical tools.
