COMPOSITE TYPE CUTOFF WALL OF STEEL TEMPORARY FACILITY AND CONSTRUCTION METHOD OF THE SAME

摘要

The present invention relates to a composite waterproofing wall of a temporary steel facility and to a construction method thereof and, more specifically, to a waterproofing wall of a temporary steel facility and to a construction method thereof, wherein the waste of members and environmental pollution can be prevented by recovering and reusing all used members after the construction of a composite temporary steel facility. In constructing the composite waterproofing wall of a temporary steel facility according to the present invention, a soil retaining plate, which is composed of steel panels, is installed not inside or between H-piles but outside the H-piles using bolting, bolting is conducted on combination grooves at regular intervals to enable H-piles to be installed easily even if the verticality of the H-piles is not constant. The bulging phenomenon of the steel panels, which is caused by the weight of mortar poured therein, can be prevented by connecting and supporting the steel panels and a seat pile using a tension member. Accordingly, environmental pollution can be prevented as a temporary facility can be disassembled easily and conveniently without interference of H-piles, materials can be reused and the materials are not buried underground after the installation of the temporary facility is finished and the curing of the waterproofing wall is finished. The waterproofing wall of a temporary facility can be installed easily when installed on H-piles with different verticalities to eliminate the inconvenience of installation and the necessity of increasing labor and can be installed freely among H-piles with various widths.
