Description

[Detailed description of the invention] The present invention relates to a water collection basin.

In conventional water collection basins, the side blocks and edge blocks were manufactured as independent and separate pieces and were constructed in separate work processes, making construction complicated. In particular, when the upper end of a cylindrical side block is narrowed into a rectangular shape and a rectangular edge block is stacked there, the long side direction at the top end of the side block is in the reciprocating direction of the road, and the short side direction is Since the rectangular edge block had to be positioned after the block had been positioned in the width direction of the road, construction was extremely troublesome.

The present invention has been made in view of and to solve the problems of the prior art, and it is an object of the present invention to provide a new water collection basin that can be constructed simply, quickly, and appropriately.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be sequentially explained below according to an illustrative embodiment.

Reference numeral 1 refers to the edge mass of the water collection basin A. The upper part has a rectangular shape similar to the conventional one, and the curb part 1a is formed on one side, while the lower part is for connection to the cylindrical side mass 3. A side mass 2 is integrally formed.

A rectangular hole 4 is drilled in the edge block 1, and the hole 4
A fitting step 6 of the lid 5 is formed around the .

The connecting side block 2 is prevented from slipping by tightly fitting the tapered surface 2c formed on the lower surface of the connecting side block 2 into the tapered concave surface 3c provided on the upper surface of the cylindrical side block 3. The inner wall surface 2a expands in diameter into a V-shape in cross section and is continuous with the inner wall surface 3a of the cylindrical side mass 3, and the outer wall surface 2b
It expands vertically or downwardly in the front view shown in FIG. 3, and further narrows downward in the side view shown in FIG. 4, so as to be continuous with the outer wall surface 3b of the cylindrical side mass 3. The reason why the connection side block 2 has such a shape is that the connection side block 2 is attached to the cylindrical side block 3.
When stacking rectangular edge blocks 1 via the cylindrical side block 3, the contact area of the connecting side block 2 with the cylindrical side block 3 is made as large as possible so that the rectangular shape is maintained even when subjected to vibrations from automobiles or loads from above. The edge mass 1 can be stably placed without tilting. Further, since the curb stone portion 1a is integrally formed with the curb block 1, the curb stone portion 1a functions as a guide wall without requiring separate installation work for the curb stone portion, thereby ensuring water collection. Moreover, since the outer wall surface 2b of the connecting side mass 2 is opened vertically or downwardly in the front view shown in FIG.
The soil used for backfilling during burial does not leave any voids, creating a structure that is easy to fill, so the edge mass 1 and the cylindrical side mass 3 will not cause the ground to sink and tilt after burying, and the inner wall surface will be maintained in cross section. Since the diameter of 2a is expanded in a V-shape, there is no possibility of dirt or weeds remaining and spoiling the aesthetic appearance, which is also good for hygiene.

The cylindrical side block 3 has a through hole 7 that passes through the inner and outer wall surfaces 3a and 3b, and joint pipes 8 and 9 such as an underdrain or an open drain (not shown) are connected in that direction in a watertight manner using mortar or the like. .

Next, a construction method for the water collection basin A constructed as described above will be explained.

First, joint pipes 8 and 9 such as underdrains or open drains are fitted into the through holes 7 and 7 and connected watertightly with mortar etc., and after positioning and burying the side block 3, an edge block is placed above the side block 3. 1 is provided on the lower surface of the connecting side block 2 with its long side facing the reciprocating direction of the road and its short side facing the width direction of the road.A tapered surface 2c is provided on the top surface of the cylindrical side block 3. By fitting tightly into the tapered concave surface 3c, the center of the connecting side block 2 and the center of the side block 3 naturally coincide, and the edge block 1 is placed on the upper surface of the side block 3 via the connecting side block 2. Stack them together. At this time, no matter what direction the joint pipes 8 and 9 are laid with respect to the side block 3, the edge block 1 is rotated relative to the side block 3 in accordance with the road laying direction. 1. The mounting position can be adjusted.

Furthermore, unlike the conventional method in which the connecting side block 2 and the edge block 1 were manufactured independently and separately, the connecting side block 2 is integrally molded with concrete below the edge block 1. As the weight increases, the tapered surface 2c provided on the lower surface of the connecting side block 2 fits tightly into the tapered concave surface 3c provided on the upper surface of the side block 3, preventing displacement. When the edge block 1 is attached to the upper surface of the connecting side block 2 via the connecting side block 2, it is possible to prevent the edge block 1 from shifting due to vibrations from an automobile or the like or a load applied from above.

In this way, in the above embodiment, the center of the connecting side block 2 and the center of the side block 3 are aligned with each other during construction, so that the construction can be carried out quickly and reliably, and the edge of the side block 3 is adjusted after construction. In order to prevent the lump 1 from shifting, a tapered surface 2c as a fitting means is provided on the lower surface of the connecting side lump 2, and this tapered surface 2c is provided on the upper surface of the side lump 3 as a tapered concave surface as a fitting means. 3c so that it fits tightly.

As described above, in the present invention, the water catchment basin is configured such that the connection side block is integrally formed below the rectangular edge block, so that the side block construction, which was conventionally performed separately, is completed. The work process and the work process of constructing the edge block are performed in one work process, which improves work efficiency, and the direction of the edge block is aligned with the cylinder on which the connecting side block is fitted and placed. Regardless of the direction in which the joint pipe connected to the side mass is installed, the installation position can be easily, quickly, smoothly, and appropriately determined in accordance with the road installation direction. By the way, the inner wall surface of the connecting side block, which is formed integrally with the edge block by concrete below the edge block, has a diameter enlarged in a figure-eight shape in cross section, so the inner wall surface of the side block on which the connecting side block is placed. Also, since the outer wall surface of the connecting side mass expands vertically or downwardly at the front and narrows downward at the side surface, it is continuous with the outer wall surface of the side mass and at the same time fits into the lower surface of the connecting side mass. Since the tapered surface serving as a connecting means is formed and is tightly fitted with the tapered concave surface provided on the upper surface of the side block, the contact area of the connection side block with the side block becomes large, preventing slippage and movement of the cylindrical The connecting side block can be stably placed on the side block, and the rectangular edge block will not tilt even when subjected to vibrations from an automobile or the like or a load from above. Moreover, as mentioned above, the outer wall surface of the connecting side block is formed vertically or downwardly expanding in front, and there is no concave surface. Therefore, after burying the edge block and the connecting side block, the backfilling soil is filled without any voids. By being pushed back, the ground will not sink and tilt. Furthermore, since the inner wall surface of the connecting side block has an enlarged diameter in a figure-eight shape in cross section, it is hygienic because dirt and weeds do not remain and impair the aesthetic appearance.
