FIELD: construction.

SUBSTANCE: invention relates to the metal sheet piles for sheet piling enclosures, in particular built on sites with free flow of groundwater, in flooded areas near rivers and shallow rivers near the shore, and can be used when constructing pits in type II and III swamps while carrying out work on pipelines. The collapsible sheet pile includes the sheet pile elements of the upper and lower tiers, equipped with lugs on the end parts of the shelves, which, when articulated, are located on the same axis and form a hole for inserting a closing element. The gap between the outer surface of the closing element and the inner surface of the lugs ranges from 1.5 to 15 mm.

EFFECT: increasing the reliability of the design of the collapsible sheet pile by increasing the load-bearing capacity of the connection unit of the sheet pile elements, as well as in increasing the ease of installation and dismantling of the collapsible sheet pile.
