A METHOD FOR THE CONSTRUCTION OF CATCHWATER DRAINS, DRAIN RIBS OR SUPPORTING RIBS, TEMPORARY SUPPORTING STRUCTURES AND WATER COLLECTING-AQUIFEROUS BLOCKS THEREFOR

摘要

A process and structure is disclosed for the construction of catchwater drains, mainly deep catchwater drains, drain ribs, supporting ribs or similar structures, wherein a trench is excavated step by step in the soil, into which water collecting-aquiferous elements are laid, then suction bodies essentially filling out the trench are placed over the water collecting-aquiferous elements. The process teaches that following the excavation of a trench-section to its full depth, inflatable hoses (5) of a temporary supporting structure (4) are consecutively laid into the trench (3), then the trench (3) is further opened and supported, and the hoses (5) of the temporary supporting structure (4) are removed one by one from the trench (3) and they are replaced by water collecting-aquiferous blocks (8) laid on the bottom (7) of the trench (3) so that they are situated at least partly in the impermeable soil layer, furthermore on top of these blocks (8) suction bodies (9) are placed consisting of granular material filled into filter bag.
