Member for temporarily restoring road surface and method for temporarily restoring road surface

Abstract

There is provided a temporary restoration member (lining mats ( 1 ), nonslip pins ( 2 ), lock pins ( 3 ), stoppers ( 4 ), fixing pins ( 5 )) for simplifying the construction work for temporarily restoring a road surface when a paved road surface (B) is excavated to lay piping, and a method for restoring the road surface using the member. Each of the lining mats ( 1 ) is a rectangular rubber plate provided with a thick central part ( 11 ), two thin side parts ( 12 ), and pinholes ( 16 ) at appropriate locations that pass through the mats from the front surface to the reverse surface. The lining mats are laid out to cover a backfilled surface so that the side edges of the mats are disposed on the paved road surface (B). Cylindrical nonslip pins ( 2 ) are driven into the pinholes, and lock pins ( 3 ) are driven into the cylindrical part of the nonslip pins to fix the lining mats. Latching protrusions ( 42 ) of stoppers ( 4 ) are inserted into the pinholes to connect adjoining mats.
