The choice of a metal sheet piling for the construction of the foundation pit

Abstract

Sheet piles are often used for fencing deep excavations. This is due, among other things, to the fact that when they are pressed, there is no negative impact on the surrounding buildings. In the course of the study, a technical and economic comparison of the domestic sheet pile L4 and its foreign analogue VL603K was carried out. The relevance of the study is confirmed by the fact that during the construction of underground parts of buildings and structures, great attention is paid to engineering measures to prevent the ingress of groundwater into the pits, as well as to strengthen the walls of the excavations from the possibility of collapse in unstable and water-bearing soils. It is also taken into account that the choice of the foundation pit construction depends on its depth, the level of groundwater and the structural scheme of the underground part of the structure, it is also necessary to carry out a static calculation to determine the thickness of the fence and its immersion depth. The analysis of sheet piles also revealed their disadvantages and advantages.

Experimental Validation of Deflections of Temporary Excavation Support Plates with the Use of 3D Modelling

“…In engineering practice, there are several ways (methods) to protect excavation walls against sliding. These include tight walls made of steel sheet piles (Larssen profiles), Berlin walls, cavity walls (concrete) formed in the soil, palisades made of piles (i.e., CFA or micro-piles), column walls made by jet injection as well as reusable system supports [ 1 , 2 , 3 ]. In practice, medium-deep and deep rope excavations are not performed without supports, with slopes having inclination corresponding to the angle of internal friction of the soil, as this would require a large strip of land and significant earthworks.…”
