The basic structure of the raising tool is a raised pipe material 2 having a predetermined height that is installed on the upper portion 11 of the side wall 10 of the side groove 1 and raises the side wall 10, and a fixing member that fixes the raised pipe material 2 to the side wall 10. And 5.

The raised pipe materials 2, 2 are implemented as a pair of two sets installed on the upper portions 11, 11 of the side walls 10, 10 on both sides of the side groove 1. Each raising pipe material 2 is arranged horizontally, and is suitably implemented with the steel material of the square pipe 20 whose total length is 500 mm to 2000 mm. Moreover, the width dimension and height of this raising pipe material 2 are each formed substantially the same as the width dimension of the upper part 11 of the side wall 10 of the side groove 1 (for example, 50-100 mm). The material is not limited to the steel material, and it is possible to implement the material using rubber or plastic (the same applies to the basic configuration of the raised pipe material 2).

As shown in FIG. 2, the raised pipe material 2 of type (1) has two hook holes 3 formed on the upper surface 2a. On the other hand, as shown in FIGS. 4 and 5, the fixing member 5 is a wire rod having a predetermined length in the vertical direction along the side wall 10 of the side groove 1 (substantially the same length as the side wall 10 and usually about 200 to 300 mm). The upper part is formed in the hook-shaped hook part 60 latched by the hook hole 3 of the said raising pipe material 2 (refer FIG. 3).

By obtaining force, the raised pipe material 2 can be firmly fixed on the side wall 10, and the side wall 10 is raised. Therefore, as shown in FIG. 5, if the cover 12 of the side groove 1 is covered on the raised pipe materials 2, 2, the upper surface level m of the raised cover 12 is adjacent to the old soil g−1. It can be aligned with the upper surface level position k of the ground g that has been raised by the height of the new soil g-3 laid as it is (about the height of the lid 12) (FIG. 1). In addition, it is preferable to adjust the height of the soil g 'on the left side of the side groove 1 in FIG.

  6-12 has shown the said (2) type raising tool.

As shown in FIG. 6, this type of raised pipe material 2 has guide pipes 2c, 2c made of round pipes having the same height as the side surface 2b at symmetrical positions except for the central portion of the outer side surface 2b. Is fixed in the vertical direction by welding. On the other hand, the fixing member 5 of this type is formed of a wire 6B formed of a nail 61 having a predetermined length (substantially the same length as the side wall 10) in the vertical direction along the side wall 10 of the side groove 1. The wire 6B is inserted into the guide pipe 2c of the raised pipe material 2 from above (FIG. 7).

Therefore, in the case of this type (2) type raising tool, similarly to the type (1), the side groove 1 is left as it is, the lid body 12 is temporarily removed, and the side walls 10, 10 on both sides facing the upper side 11, 11 are exposed. The raised pipe material 2 is placed in such an arrangement that the guide pipe 2c faces outward, that is, the guide pipe 2c is positioned perpendicular to the outer surfaces of the side walls 10 and 10 on both sides of the side groove 1 respectively. Then, by simply embedding the wire 6B of the fixing member 5 along the outside of the side wall 10 in the vertical direction into the soil, a supporting force can be obtained like a pile, and the raised pipe material 2 can be firmly fixed on the side wall 10. And fixed integrally. Finally, if the lid 12 is covered as it is, the raising of the side wall 10 is completed.

In addition, in this (2) type, it is also possible to implement in a form in which the upper part of the wire material such as the nail 61 is fixed to the outer surface 2b of the raised pipe material 2 by welding or the like without using the guide pipe 2c. Yes (illustration omitted).

Moreover, FIGS. 9-12 has shown different embodiment in the case of the raising tool of said (2) type. In this embodiment, it is suitable when the raised pipe material 2 is small. As illustrated in FIG. 9, the guide member is a protruding guide fitting 2 e having an L-shaped cross section, and is formed in a horizontal surface portion 24 having a vertical surface portion 23 and a guide through hole 25 by an L-shaped angle. The vertical surface portion 23 is fixed to the outer surface 2b of the raised pipe member 2 by welding, and the horizontal surface portion 24 protrudes outward.

Therefore, as shown in FIG. 10, even when the raised pipe material 2 has a width W ′ smaller than the width W of the side wall 10 of the side groove 1, the guide through hole 25 is provided by the protruding guide fitting 2 e having the L-shaped cross section. Can be disposed on the extended upper portion of the outer surface of the side wall 10 of the side groove 1 and is inserted from above into the guide through hole 25 of the horizontal surface portion 24 of the guide member. The wire 6 </ b> B such as the nail 61 is disposed along the outer surface of the side wall 1.

FIG. 11 shows a different form of the protruding guide fitting. The protruding guide fitting 2f is formed of a U-shaped cross-sectional fitting. That is, it is formed in the vertical surface portion 23 and the upper horizontal surface portion 24a and the lower horizontal surface portion 24b each having guide through holes 25a and 25b in two upper and lower stages. Therefore, the wire rod 6B such as the nail 61 of the fixing member 5 has two upper and lower guide through holes 25a and 25b of the upper horizontal surface portion 24a and the lower horizontal surface portion 24b protruding in the direction of the width dimension W ′ of the raised pipe material 2. It is inserted from above and maintained in a non-moving state in the vertical direction without swinging, and is supported and positioned and fixed along the outer surface of the side wall 10 of the side groove 1 (FIG. 12).

  FIG. 13 and FIG. 14 show different raising means of the type (2).

The guide member of the raised pipe material 2 in the figure is formed by a handle-shaped guide fitting 2d instead of the round pipe guide pipe 2c and the protruding guide fittings 2e and 2f. This guide metal fitting 2d has a thickness of about 1 to 2 mm, a width of about 50 to 100 mm, and a height of about 25 to 40 mm having an insertion hole 21 penetrating vertically so that a fixing member 5 of a flat plate 6C described later is inserted. In this way, it is fixed to the left and right sides of the outer surface 2b of the raised pipe material 2 by welding.

The flat plate 6C used for the fixing member 5 is made of thin flat steel (thickness: about 1 to 2 mm, width: about 50 to 100 mm, length: about 100 to 200 mm) instead of the wire material such as the nail 61. This is carried out by forming the lower end portion into a sharp portion 62 having a V shape.

Therefore, in the case of the raising tool of the present embodiment, the flat plate 6C (fixing member 5) is inserted from above the insertion hole 21 of the guide fitting 2d as in the case where the wire 6B and the guide pipe 2c are used, and the side wall By embedding vertically in the ground along the outer side of 10, the sharpened portion 62 projects downward like a wedge (pile) to obtain a supporting force, and the raised pipe material 2 and the side wall 10 are suspended. Fixed integrally. In particular, in a so-called all-weather gland g in which asphalt is paved as shown in FIG. 14, this thin flat plate is used when it is difficult to insert the fixture 5 between the gland g-1 ′ and the side groove 1 (side wall 10). The side grooves can be easily raised by using the fixing tool 5 of 6C, and a new asphalt g-3 ′ can be directly laid on the old asphalt pavement g-1 ′ of the surface layer.

However, in this embodiment, it is also possible to carry out by fixing the upper part of the flat plate 6C to the outer side surface 2b of the raised pipe material 2 without using the guide fitting 2d (not shown).

In addition, the form which attaches the level adjustment member 4 to the lower bottom face of the raising pipe material 2 illustrated in FIG. 15 is implemented suitably. That is, the raising tool of the example shown in the figure is provided with a level adjusting member 4 for adjusting the raising level on the lower bottom surface of the raising pipe material 2 so that the raising level of the side wall 10 of the side groove 1 can be adjusted. . The level adjustment member 4 is formed at a desired height H to be raised. The material, shape, size, and the like of the level adjusting member 4 are not limited. For example, in addition to a round bar as shown in the illustrated example, a metal fitting, a stone, a plastic cushioning material, a rubber packing, or a mortar is stacked. Etc. can be formed. Therefore, even when the height levels of the side walls 10 and 10 of the side groove 1 are different from those at the time of installation, the level adjusting member 4 is interposed between the raised pipe material 2 and the side wall 10 of the side groove 1, thereby Fine adjustment of the desired raising level at 10 and 10 is possible.

Further, when the level adjusting member 4 is interposed between the upper portion 11 (upper surface) of the side wall 10 of the side groove 1 and the raised pipe material 2, a gap that can be drained by the height H of the level adjusting member 4. 9 is formed, it also has a secondary function of enhancing the drainage performance from the adjacent ground side to the side groove 1 by utilizing this gap 9.

Moreover, FIG. 16 has shown the application example of each type of raising tool of said (1) and (2). That is, the fixing member 5 (6A, 6B, 6C) is placed on the outer surface of the side wall 10 at a position near the side wall 10 on the ground g adjacent to the side wall 10 of the side groove 1 with the existing side groove 1 and the lid body 12 intact. ), And is installed and fixed so that the upper surface of the raised pipe material 2 is at a level position k (new soil g-3) higher than the ground g. The upper surface level of the lid 12 of the side groove 11 and the upper surface level k of the new soil g-3 cannot be matched, but the raised pipe material 2 functions as a dam plate, so a new soil g-3 is laid. Even so, it can be dammed immediately before the side groove 1. In the figure, reference numeral 90 denotes a retaining wall on the opposite side.

  FIGS. 17-24 has shown the said (3) type raising means.

The fixing member 5 is formed of a vertical thin flat steel side plate 7 having a joining piece 70 on the upper side and a flat plate of a protruding piece 71 on the lower side. This side plate 7 is installed in the left-right symmetrical position except the center part of the outer side surface 2b and the inner side surface of the said raising pipe material 2. As shown in FIG. That is, it is composed of a total of four side plates 7..., One pair (two) on the left inner / outer surface and one pair (two) on the right inner / outer surface. However, it is also possible to install the side plate 7 only on one side of the outer side 2b or the inner side (not shown). In any case, a plurality of upper joint pieces 70 in the upper half portion of the side plate 7 are welded to the side surface 2b of the raised pipe material 2 and a plurality of lower projecting pieces 71 in the lower half portion are protruded downward. ing.

Therefore, according to the raising tool of the present embodiment, the hollow portions in the downward projecting pieces 71, 71 of the pair of side plates 7, 7 attached to the raised pipe material 2 are replaced with the side walls 10, 10 on both sides of the side groove 1.
