<p>The subject of invention, a prefabricated reinforced concrete retention wall with a foundation toe of variable width, relates to construction of retention walls. The prefabricated reinforced concrete retention wall with a foundation toe of variable width is intended for permanent or temporary supporting of slopes and consists of the following parts: foundation toe (1), pressure slab (2), additional pressure slab (3), backside slab (4), additional backside slab (5), basic element (6), corner element (7), block (8) and rib reinforcement (9). Pressure slabs (2) and, if needed, additional pressure slabs (3) are laid on the foundation ground at interspaces which allow foundation toe (1) elements to be laid between them. The backside (4) and, when needed, additional backside slab (5), depending on physical properties of soil, is laid on the bearing surface of the backside and additional backside slab (11). Stacking of basic elements (6) and, when needed, corner elements (7) on bearing surface of the ribs (12) is started at the adjacent foundation toe (1). After the desired wall height has been reached, the rib reinforcement is inserted and tensioned.</p> |
