Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated storage container for connecting an upstream side groove and a downstream side groove. The present invention also relates to a gutter construction method using the reservoir.

[0002]

2. Description of the Related Art In a gutter, a basin (a basin for precipitating mud or sand) is usually provided every 30 to 40 meters. Conventionally, this masu has been constructed by in-situ construction or by laying concrete masu blocks.

FIG. 9 shows an example of the square block a, which is incorporated in a side groove constructed by using the side groove block b shown in FIGS. The gutter block b is formed by connecting the upper portions of the opposite side walls c, c integrally at both ends thereof with connecting beams d so that the lower portion e is in an open state, and the end portions thereof are placed on a concrete foundation f formed at the bottom of the excavation groove. The gutters are laid in abutting order, and bottom-filling concrete g is placed in the lower part between the side walls to construct the side groove h. The measure block a to be incorporated in the gutter is formed in a bottomed rectangular tube shape with an open upper side, and upper ends for fitting the end portions of the gutter block to the opposing standing wall parts i and i. Open rectangular openings j1 and j2 were provided.

Then, the procedure for connecting the upstream side groove k and the downstream side groove m by using the measure block a and constructing the storage measure o at the connecting portion will be described with reference to FIGS. It seemed. First, the measure block a is installed in a portion where the concrete foundation g is lowered one step, and the rectangular opening j1 on one side thereof is fitted with the end portion p of the gutter block that constructs an upstream side gutter, The other rectangular opening j2 is fitted with an end portion q of the gutter block that forms a downstream side gutter, and then occurs between the inner surface of the opening and the outer surface of the end portion of the gutter block. The gap portion r was filled with mortar s to perform the water stop treatment.

[0005]

However, in the case of constructing a basin by cast-in-place construction, a lot of man-hours are required, such as a formwork process, a reinforcing bar process, a concrete placing process, and a subsequent demolding process. Construction becomes complicated and there is a problem that the construction efficiency is poor.

On the other hand, when the measure block is used, it is necessary to adapt a rectangular opening provided in the measure block to the width dimension of the gutter block, and therefore it is necessary to manufacture various kinds of measure blocks having different opening widths. There was a great deal of uneconomical cost and inventory management. Further, since it was necessary to fill the gap with mortar after fitting the end portion of the gutter block into the opening of the Masu block, it took a lot of time and effort for the construction to improve the construction efficiency. There was room.

It is an object of the present invention to provide an assembling type storage basin capable of solving such problems, and an object of the present invention is to provide a gutter construction method using the assembling type storage basin.

[0019]

The present invention has the following excellent effects, and can be said to have many advantages practically and economically. Since the measure body used in the present invention has the same structure as that of the conventional gate-shaped gutter block, the conventional gutter block can be used as it is as a measure body, and there is no need to specially design and manufacture the measure block. . Then, by combining an end face plate having an appropriate opening with the measure block, a desired storage measure can be constructed. In the conventional measure block, as described above, it was necessary to design and manufacture various types of measure blocks according to the width of the side groove block, but when the present invention is adopted, the measure main body is made the same, The width of the gutter block can be easily accommodated simply by changing the end face plate to be combined therewith. Therefore, the manufacturing cost of the tub can be significantly reduced.

The insert is embedded in the inner surface of the end plate by aligning with the bolt insertion hole on the main body side, and the outer surface of the end plate is aligned with the bolt insertion hole provided on the side groove block side. The insert is buried.
Therefore, the connection between the end face plate and the main body of the box and the connection between the end face plate and the gutter block can be performed by directly utilizing the bolt insertion holes in the conventional block provided for connecting the blocks to each other. No connecting means required. Because of this, the blocks can be connected to each other easily and inexpensively.

The water stoppage at the connecting portion between the end face plate and the box main body and at the connecting portion between the end face plate and the gutter block can be easily and efficiently performed by a dry method in which an elastic sealing material is interposed between the both. Therefore, it is not necessary to perform the conventional construction such as stopping the gap portion by filling the mortar with water to reduce the construction period and the construction cost.
