PREFABRICATED COMPONENTS FOR A WALL IN THE GROUND MADE OF PREFABRICATED AND ONE-PIECE SECTIONS, CONSTRUCTION OF THE WALL USING THESE COMPONENTS AND METHOD OF ERECTING THE SAME

摘要

Prefabricated components (1) are disclosed for a wall in the ground made up of prefabricated and one-piece sections. The said prefabricated components consist of a reinforcing shell and a concrete body with longitudinal concave grooves (2) along abutting faces, the grooves being displaced towards one of the longitudinal faces of the body, an arrangement which creates jutting limbs of greater (3) and lesser (4) width. The reinforcing shell consists of an outer laminated reinforcement (6), transverse rods (7) and intersecting rods (5), the latter being rigidly connected to the laminated reinforcement (6) and the transverse rods (7). The transverse rods (7) and laminated reinforcement (6) can be provided with protruding sections (9, 10, 11). The sectional wall in the ground constructed using the above mentioned prefabricated components (1) is provided with continuous transverse reinforcement on the side opposite to the laminated reinforcement (6). A method of erecting the sectional wall involves creating a trench with recesses, setting up the prefabricated components (1) with protruding sections (9, 10) and components without protruding sections in the recesses by a specified method and concreting the solid wall sections between adjacent prefabricated components.
