摘要： PURPOSE: To install and execute a longitudinal sound-insulating wall with a skirt section rapidly. CONSTITUTION: A sound-insulating wall 1 has a skirt section 3 bent to the side edge side of a barrier curb when the sound-insulating wall 1 is installed to the side edge of the barrier curb 30. A first hanging hook mounted on the side end face of the sound-insulating wall 1 is hung up by using a winding means, a mounting member 11 for suspension is set up to the sound-insulating wall 1, a section between a second hanging hook 14 fitted to the mounting member 11 for suspension on the upper end face side of the sound-insulating wall 1 and the winding means is connected by a member 22 for suspension, and the first hanging hook side is lowered by the winding means 20 and the sound-insulating wall 1 is hung down finally by the second hanging hook 14. Accordingly, the whole sound-insulating wall 1 is inclined to the reverse side to the side edge of the barrier curb 30, the sound-insulating wall 1 is installed onto the side edge of the barrier curb 30 under a hung-down state, and the sound-insulating walls 1 are juxtaposed in a row.

摘要： PURPOSE:To prevent a constructed base surface from becoming fragile due to rain water or the like, and collapsing, by integrally incorporating an anchor part adapted to be embedded partly or entirely in earth, with one side surface of a water-permeable concrete board. CONSTITUTION:An anchor part 3 adapted to be partly or entirely embedded in earth is integrally incorporated with one side surface of a water-permeable concrete board which constitutes a sheathing wall. Further, the anchor part 3 is partly or entirely embedded in the ground so as to hold the concrete board 2 in an upright posture without occurrence of side-slip, tilt or turn-over. With this arrangement, it is possible to prevent occurrence of side-slip, tilt or turn- over even though main piles are not used, thereby it is possible to enhance the workability. Further, rain water having penetrated into a constructed base surface can be smoothly discharged outside thereof, and thereby it is possible to prevent the constructed base surface from becoming fragile or from collapsing.
