TECHNOLOGY OF SHEET PILE RETAINING WALL CONSTRUCTION IN THE RECONSTRUCTION OF AN UNDERGROUND CIVIL DEFENSE STRUCTURE LOCATED ON A SLOPE

Abstract

The performing of specific works in modern construction requires the construction of foundations with increased weight-bearing capacity, deep pits in the soil, and ensuring the stability of slope walls in the soil.

The analysis of literature sources provides complete information about metal sheet piles and their installation technology used in the construction of protective structures. Based on this, it is proposed to consider the technology of installing a retaining wall made of sheet piles on a slope while performing construction work on the reconstruction of a dual-purpose structure.

The main method of immersion of sheet piles, in conditions of dense construction is the vibration method, pressing the pile into the ground. Larsen's steel sheet pile GU-33N was used for the construction of the sheet pile retaining wall. An important advantage of vibratory pile drivers is the ability to perform not only effective immersion, but also to remove the sheet pile from the soil under static efforts.

Larsen-type sheet pile locking structures do not deform when pressed in, which makes it possible to reuse it. The use of the indentation method during sheet pile driving is especially relevant in dense urban areas, as it eliminates dangerous vibrations, noise, air pollution, and reduces energy consumption. The use of mobile units based on modern excavators makes it possible not only to sink sheet piles in a saving mode, but also to remove them if necessary and reuse them.
