Description

[Detailed description of the invention] The present invention relates to a side gutter with earth retaining.

In general, a gutter consists of a pair of side walls provided along the edge of the road and a bottom wall provided at the bottom between these side walls, and the pair of side walls are supported on pedestals and the bottom wall is provided at the bottom between these side walls. The walls are formed by pouring concrete on site. On the other hand, if this gutter forms a border with another road or field that is slightly higher, earth shoring is required to prevent the soil from collapsing from this higher road or field. Conventionally, this shoring was formed by pouring concrete on-site, which required a large amount of process and labor, resulting in low workability. On the other hand, recently, a gutter has been proposed in which an auxiliary side wall for height adjustment is attached above the gutter so that the left and right height can be freely set.
(See Publication No. 42600). However, the gutter of this structure is
Since the gutter cover is placed on top of the auxiliary side wall, for example, the height of the opposite side wall can be left as is, but it cannot be applied to the case where the height of the auxiliary side wall is higher. Since the side gutter is not an assembly type and the side wall and bottom wall are integrally formed, there is a drawback that gutter bodies of various sizes must be prepared in order to adjust the height and width. On the other hand, a prefabricated side gutter requires struts to hold the pair of side walls, but the struts get in the way of assembling a retaining wall, making it impossible to assemble the retaining wall.

An object of the present invention is to provide a side gutter with a shingle that can be easily assembled into a prefabricated gutter.

Embodiments of the present invention will be described with reference to the drawings. Figs.
This side gutter 10 has a pair of side walls 12,1
2', a bottom wall 14 provided at the bottom between these side walls 12, 12', and a retaining wall 16 provided in alignment with one side wall 12. Incidentally, the side walls 12, 12', the bottom wall 14 and the retaining wall 16 are made of concrete.

As shown in FIG. 1, the side walls 12, 12' are supported by fitting into a pair of recesses 19, 19' of the pedestal 18 at their joints, and the bottom wall 14 is formed by pouring concrete on site. be done. In addition, a pair of side walls 12,
12' is a lid engaging surface 12a with which the gutter lid 20 engages;
12'a on the upper surface, but one lid engaging surface 1
2'a is a recess that extends continuously inside the side wall 12'. Further, in FIGS. 3 and 4, reference numeral 20a indicates a grid-shaped drain hole provided in the gutter cover 20.

The side walls 12, 12' are joined at their opposite ends by concrete struts 22, each of which has legs 23, 23' projecting downwardly with a small width. 23, 23' engage with stepped portions 12b, 12'b provided on the outside of the ends of the side walls 12, 12'.
Therefore, the pair of side walls 12, 12' are firmly held by the pedestal 18 and the strut 22 at a constant distance.

The earth retaining wall 16 is pre-molded with the same length as the side walls 12, 12', and the joint portion is formed between the side walls 12, 12'.
12'. Earth retaining wall 16
The struts 22 are stacked on the stepped portion 12b that extends continuously over the entire length of one side wall 12 on the outside.
The corresponding legs 23 are engaged in engagement holes 16a that are formed at the joints of the retaining walls 16 and also serve as drainage holes. As can be seen from FIG. 1, the insertion hole 16a
Since the upper part of the drain hole is spaced apart from the upper surface of the leg 23, the strut 22 can be easily inserted into the insertion hole 16a even after the retaining wall 16 is stacked up. To the left of the retaining wall 16 is a slightly elevated road or field 24, and to the right of the side wall 12' is a low road 24'.

The retaining wall 16 is connected to the lid engaging surface 12a of the side wall 12 by an appropriate part of the side wall 12 using a connecting fitting (not shown), for example, an L-shaped connecting fitting. The retaining wall 16 and the adjacent side walls 12, 12' are connected to each other by connecting fittings (not shown). Therefore,
The plurality of side walls 12' and the plurality of side walls 12 and the retaining wall 16 are integrally connected by these connecting fittings. Moreover, the earth pressure that the side wall 12 and the earth retaining wall 16 receive is not so great because it is from a slightly high road or field, but this earth pressure causes the side wall 12 and the earth retaining wall 16 to Preferably, suitable support means are provided for the side wall 12' or the pedestal 18 to prevent it from tipping over to the right side in the drawings. For example, a connecting rod may be provided to connect the side walls 12, 12' so as to be buried in the bottom wall 14 poured with concrete on site, or a connecting rod may be provided between the lower edge of the side wall 12 and the pedestal 18 to be buried in the bottom wall 14. An L-shaped or triangular support fitting can be provided which is fixed across the two.

According to the present invention, as described above, the earth retaining wall has an insertion hole that also serves as a drain hole for inserting the leg strut necessary for the prefabricated side gutter, so that it is not interfered with by the leg strut. In addition, since the insertion hole of this strut also serves as a drainage hole, drainage holes can be easily formed, making side gutters with earthstops highly workable and economical. There are practical benefits that can be put together.
