Abstract
Choice of sheet piling method for bank protection in conditions of dense urban development
Incoming article date: 08.10.2022The article is devoted to the analysis of sheet pile driving methods during the construction of a bank protection structure in dense urban areas. Four methods are considered in the paper: driving, vibration immersion (if necessary using leader drilling), indentation, vibroimpact. Comparative characteristics of the above methods of immersion are given. It is concluded that in conditions of dense urban development: a) the driving method is the least preferable, due to severe noise pollution and a negative impact on foundations near the work site; b) in the presence of dense soils, the methods of indentation or vibro-immersion are not suitable, and vibro-impact immersion should be used; c) in the presence of weak soils, it is possible to use both the indentation method and vibration immersion; d) in the conditions of a limited construction site, vibration immersion may be the best immersion method. The result of the work is the creation of a block diagram of the algorithm for choosing the method of piling for bank protection with heterogeneous soils.
