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.

Description

TECHNICAL FIELD[0001]The present invention relates to a lining member for temporarily restoring a road surface when the road surface is to be excavated and construction work performed on gas, water, sewer, or other pipelines; and to a method for temporarily restoring a road surface using the lining member.BACKGROUND ART[0002]A channel is excavated in construction work for laying pipes when new piping is to be buried under a road surface, or in construction work for laying temporary or permanent piping when it is necessary to repair or replace previously buried pipes such as gas, water, or sewer pipes. However, each section (normally one day's construction work) of the excavated channel is temporarily backfilled, and a temporary asphalt paving (temporary restoration construction work) is applied so as not to impede the passing of vehicles and pedestrians.[0003]When the construction work on the piping is complete, the asphalt paving used for temporary restoration construction work is ...

AI Technical Summary

Benefits of technology

[0029]The present invention has the above structure, does not require that a surface-compacted body or a simulated roadbed such as that used in conventional methods be used in the temporary restoration construction work of a paved road surface, and allows costs and construction work to be streamlined. The present invention also can respond flexibly to further surface compaction of the backfill dirt or sand after the temporary restoration due to vehicles running on the surface, without impeding the vehicles in any way. Furthermore, the thin side parts jut out to the paved road surface, and therefore the backfill dirt or sand does not scatter.

Problems solved by technology

The asphalt used in temporary restoration construction work thus ultimately ends up as industrial waste, and therefore temporary paving is not desirable in temporary restoration construction work in view of efficiency in the construction work, resource conservation, environmental issues, and the like.
