FILLING REINFORCING MATERIAL AND REINFORCING FILLING

摘要

PROBLEM TO BE SOLVED: To improve rust prevention force, tensile force, pulling resistance force in soil and execution and reduce an execution cost by providing a number of embossing projections and/or a number of punching projections on one surface of the longitudinal direction of a strip-like thin plate steel plate at prescribed intervals. ;SOLUTION: For instance, a number of embossing projections 21 whose cross section is trapezoid are formed by continuous press processing on the surface of a hot dip galvanized steel plate with very thick thickness wound in the form of a roll in long length having 2 mm thick and 10 mm wide to constitute a tensile material 1. The planar shape of the embossing projection 21 is a circle, for instance, having a diameter of 2 cm and height of 3 mm, and formed at intervals of 5 cm. In addition, coupling holes 3 of a diameter of 1 cm are provided on both sides side edge part at intervals of about 25 cm. Thereby rust prevention force, tensile force, pulling resistance force in soil and execution can be improved and an execution cost can be reduced.;COPYRIGHT: (C)1999,JPO
