  • the pressure member/simulated roadbed material and the rubber mat are in a two-layer structure, as disclosed in Patent Documents 1 and 2.
  • the weight of the vehicles is received by the pressure members/simulated roadbed material, and therefore no particular problems are engendered.
  • the structure of the pressure members is complicated, and production costs commensurate with the simulated roadbed are required, so that problems are presented in terms of high expenses for either prior art method.
  • the present invention proposes a novel member for temporarily restoring a road surface and a method for temporarily restoring a road surface using the member, in which construction work is simplified by employing a simple temporary restoration member, and vehicles are unlikely to be impeded when running over the temporarily restored surface.
  • the member for temporarily restoring a road surface (claims 1 , 10 , and 12 ) comprises a lining mat, a nonslip pin, a lock pin, a stopper, and a fixing pin;
  • the lining mat is formed from a rectangular rubber plate, a triangular rubber plate, or a rubber plate of another polygonal shape having appropriate rigidity;
  • the lining mat is provided with a thick central part in which a central portion corresponding to an excavation of the road surface is thickly formed, thin side parts wherein predetermined sides of the thick central part are thinly formed, and pinholes that pass completely through the mat from a front surface to a reverse surface at appropriate sites on the thick central part near the corners;

  • the method for temporarily restoring a road surface according to the present invention (claim 20 ) is characterized in that a stopper and a fixing pin are employed to fix a lining mat in the method for temporarily restoring a road surface, the stopper is disposed on the lower surface of each of the adjoining lining mats, latching protrusions are installed in the pinholes, and the fixing pin is driven via the through hole of the stopper that is positioned protruding from the excavation ground surface outside the backfill area from which only the paved surface has been removed and into the ground to fix the lining mat.
  • the excavation site In order to temporarily restore the excavation site after the paved road surface has been excavated to perform predetermined construction work, the excavation site is backfilled nearly to the height of the road surface, and the excavation channel is covered by a single lining mat or connected lining mats having a predetermined shape/dimensions corresponding to the shape (planar shape) of the excavation channel.
  • the backfilled site is temporarily restored by placing the lining mats in a particular manner so that the thin side parts of the lining mats are positioned on the paved road surface and the thick central parts are positioned above the backfilled site, and driving the nonslip pins and the lock pins into the backfill dirt to fix the lining mats, or by installing the latching protrusions of the stoppers in the pinholes of the lining mats to couple the stoppers to the lining mats and fixing the stoppers with the fixing pins.
  • each of the nonslip pins and the lock pins are employed to fix the lining mats, as in the invention of claim 16 , each of the nonslip pins is thick and driven in to a shallow point, the pins are readily driven in, and sufficient strength is provided even when force is applied in a lateral direction. Also, each of the lock pins has a small diameter, and therefore can readily be driven in to a deep point.
  • the latching protrusions are installed in the pinholes, and the fixing pins are driven into an unexcavated site rather than the backfilled site of the excavation channel to firmly fix the lining mats.
  • the member for use in construction work for temporarily restoring a road surface according to the present invention (claim 15 ) is configured as a plurality of ruler plates formed in shapes corresponding to an excavation width of a road surface, and corresponding to the shape of the thick central part in the lining mats of claims 1 to 6 that have a variety of dimensions and shapes.
  • an appropriate shape is selected for the ruler plates and the ruler plates are laid out in a configuration matching the shape of the excavation channel.
  • the paved surface of the road is cut into and channel excavation is performed following the ruler plates, and lining mats that correspond to the ruler plates are used to temporarily restore the road surface.
  • the shape and dimensions of the lining mats to be used in the construction work for temporarily restoring a road surface are determined by the arrangement of the ruler plates that corresponds to the shape of the excavation channel, and therefore the lining mats can reliably cover the backfilled site.
  • the lining mat When the lining mat has thin side parts provided to the four peripheral edges (claim 2 ), the lining mat is primarily used for temporarily restoring an excavation hole, or is used as a stand-alone lining mat or in combination with a secondary lining mat.
  • the lining mat according to claim 3 is a triangular lining mat having thin side parts provided to a base side edge and apex portion, and can accommodate a case in which the excavation channel is excavated in a curve.
  • the lining mat according to claim 4 has thin side parts provided to appropriate peripheral edges of the lining mat, and a linking protrusion that corresponds to the shape of an empty space underneath the thin side parts provided to the peripheral edge on which no thin side part is formed; and is used as the secondary lining mat of the lining mat according to claim 2 .
  • the entirety of the mat has a long rectangular shape, the thick central part corresponds to the width of the excavation channel in the road surface, a coupling protrusion made to protrude from a lower portion of the lining mat is provided to an end surface on one side, and a coupling depression that corresponds to the coupling protrusion is provided to an end surface on the other side.
  • the coupling protrusion is fitted into the coupling depression of an adjoining lining mat to integrally connect the lining mats in a line, and the mats are therefore used in restoration construction work in a case where a long excavation channel is excavated.
  • the lining mat according to claim 6 has a plurality of shallow depressions that are oriented parallel to a side edge provided to the bottom surface of the thick central part.
  • the lining mat according to claims 7 and 8 has a reinforcing metal mesh member installed in the interior, or has a two-layer structure in which a hard rubber material is formed on the front surface and a slightly soft rubber material is formed on the reverse surface, reinforcing the lining mat and thereby improving the durability thereof.
  • the lining mat according to claim 9 has small prongs, very small protrusions, fine channels, or the like formed on the front surface to impart a nonslip function, allowing for the safe passage of pedestrians on the restored road surface (lining mats).
  • both pins receive sufficient weight from the moving vehicles and sink together with the downward bulge of the lining mat at the same time that the backfilled surface sinks due to the vehicles running thereon after temporary restoration, so that the pins do not protrude from the top surface of the lining mat.
  • 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.

  • the overall length is such that the nonslip pin 2 can be inserted into the pinhole 16 of the lining mat 1 and have an appropriate length protrude from the bottom surface of the lining mat when inserted (a length sufficient to prevent the lining mat 1 from slipping laterally under the force of a lateral slipping action from a moving vehicle as described hereinafter, and to allow the pin to be readily driven into the surface-compacted, backfilled ground).
  • Each of the lock pins 3 is shaped so that the pin can be inserted into the cylindrical part of the nonslip pin 2 and so that the inserted head part 31 fits precisely inside the head part 21 of the nonslip pin 2 .

  • Each of the fixing pins 5 is given a length that provides enough strength to sufficiently secure the lining mat 1 when the fixing pin 5 is driven into the exposed ground surface F via the through hole 43 .
  • the method for temporarily restoring a road surface according to the present invention is one in which, when the paved road surface B is to be excavated (the excavation channel C is to be formed), the piping A inside the excavation channel is replaced and installed, or other predetermined construction work is performed, the above-described member for temporary restoration is used to temporarily restore the road surface so that, after the day's construction work is complete, the excavation channel C will not impede the passage of vehicles or pedestrians.
  • the excavation channel C is excavated ( FIG. 3 ) within the range of the stripped portion of the road surface B, leaving unexcavated portions F on the edges at either side.
  • dirt or sand (usually only sand is used) G is used to backfill the excavation channel C.

  • the ruler plates 6 are combined and the excavation channel C is excavated when the backfilled surface is to be covered by the lining mats 1 . Therefore, when the lining mats 1 a , 1 b , 1 c . . . that correspond to the shape/dimensions of the ruler plates 6 a , 6 b , 6 c . . . used in the road surface cutter operation are used, the backfilled excavation channel C can be reliably covered by the lining mats 1 . In other words, the method for temporary restoration using the lining mats 1 can attain perfect coverage without the mats overlapping or gaps appearing therebetween, by using the ruler plates 6 .
  • the lining mats 1 laid out so as to cover the backfilled surface are integrally connected, with the coupling protrusion and the coupling depression 19 of adjoining lining mats 1 fitted together.

  • adjoining lining mats 1 are connected together by fitting together the coupling protrusions 18 and the coupling depressions 19 .
  • the adjoining lining mats 1 are also coupled using the stoppers 4 , allowing the lining mats 1 to be completely integrated into one body, and the lining mats 1 to be more effectively fixed.
  • the end edges 17 of the lining mats 1 do not buck away from the paved road surface C, vehicles can run over the road surface unimpeded, and the backfill dirt or sand G is not scattered, even when the thick central parts 11 of the lining mats 1 sink into the ground. This is achieved by reducing the thickness of the side parts 2 .
  • the thick central part 11 of each of the lining mats 1 is formed bulging upward, and the depressions 15 are formed in the reverse surface of each of the thick central parts 11 of the lining mats 1 , thereby allowing the present method to be used to solve the problems derived from the backfill dirt or sand G sinking due to the additional surface compaction of the backfill dirt or sand G when vehicles run on top of the lining mats 1 after temporary restoration has been performed. Furthermore, rainwater does not collect on the lining mats 1 during rainy weather because the thick central part 11 bulges upward.
  • the surface area of the exposed head parts is made appropriately large, so that in a case where the weight of moving vehicles is applied, the head parts are pressed downward together with the lining mats 1 , sink together with the thick central part 11 of each of the lining mats 1 , and are maintained in that state.
  • the head parts therefore do not protrude from the top surface even when the lining mats 1 have sunk down.

  • a rectangular excavation hole E is excavated in the paved road surface B, the excavation hole E is backfilled by dirt or sand G after predetermined construction work has been performed, and the backfilled sites are covered by the lining mats 1 B, 1 C.
  • the backfilled site is therefore covered by a single lining mat 1 B, and the above-described nonslip pins 2 and lock pins 3 are used to fix the lining mat 1 B in place, in a case where the excavation hole E is a single rectangular hole.
  • the stoppers 4 b and the fixing pins 5 may be used to fix the lining mat.

  • Each of the linking protrusions 111 is positioned below a thin side part 12 a of the lining mat 1 B, the top surfaces (nonslip surfaces) are provided consecutively in a level manner, and the lining mats 1 B, 1 C are fixed in place. Of course, it is also possible to lay out the lining mats 1 C consecutively.
