Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter for draining rainwater or miscellaneous drainage, which can be attached to a gutter body by adjusting the bottom plate horizontally or at an arbitrary slope.
The present invention relates to a variable slope type gutter.

[0002]

2. Description of the Related Art In order to remove rainwater at an early stage, the bottom slab of a gutter body, which is joined in series to form a gutter, is formed with a downward slope from an upstream end to a downstream end, It is sufficient to secure the required water conveyance gradient along the length direction. In the variable gradient type gutter disclosed in Japanese Utility Model Publication No. 56-51113, the upper portions of the left and right side plates of the gutter body are connected by horizontal beam portions at the front and rear ends, and the lower portions of the left and right bottom plates are completely opened. At the laying site, bottom slab concrete is placed in line with the water transfer gradient.

[0003] In the procedure for constructing the variable slope type gutter, after laying foundation stones on the bottom of the excavation trench in the ground and compacting them with a rammer or the like, the concrete is placed by a ready-mixed concrete truck after a while. After the basic concrete has hardened to a predetermined strength, a predetermined number of gutter main bodies are laid in sequence, bottom slab concrete is poured from the top opening of the gutter main body, and leveling and finishing is performed according to the designed water transfer gradient.

However, in this variable gradient type gutter,
There is a problem that the overall construction period is long because of the large number of steps such as compaction of foundation stones, placing of concrete, placing of slab concrete and leveling. Further, since it takes a lot of time to place concrete from the ready-mixed concrete car, it causes traffic obstruction such as road closure and one-way traffic for a long time. Inability to pass water immediately after placing the slab concrete is also a factor that impedes the shortening of the process.

Further, since the bottom slab concrete must be cast and leveled and finished from the relatively narrow opening of the gutter body, the work efficiency is poor, and the slope of the top surface of the bottom slab concrete is designed for water conveyance. It takes a lot of time to finish on a gradient. In reality, it is impossible to achieve the designed slope and finish.

Conventionally, this type of gutter has a depth standard of water passage of 10 cm. For example, when the standard of 30 cm height is changed to the standard of 40 cm height, the product length is 2 m. The gradient of 10 cm difference is 5%, and the gradient adjustment finish per one is possible. However,
It takes a lot of labor and time from the viewpoint of the work space.

[0007] This is usually 10 to 50 products of the same height
More than one book is laid in the longitudinal direction, for example, product length 2m
It is impossible to obtain a slope of 5% with 10 products, that is, with a length of 20 m. That is, the standard for the terminal is a height of 1 m. Therefore, with a 20m laying and a 10cm drop, 0.5%
I can't get much with the gradient of. It is practically impossible to finish a 10 cm drop with an extension of 20 m.

If the method as shown in FIG. 17 is performed, the standard depth difference is 10 cm and the gradient is 5%, and the difference is 10% when the difference is 20 cm. However, the finish in the width of 30 cm to 60 cm is the same as the previous age. Is. It cannot be said that the finishing of the horizontal part is realistic as designed. Since the finish is inaccurate in this way, it is pointed out that there are many examples of construction in which the required flow rate and flow rate are not obtained.

Furthermore, foundation stones, concrete foundations,
All of the processes related to slab concrete require manual work, and as described above, each process is interrupted and chopped into pieces, resulting in a shortage of construction workers, which is currently a serious problem. This is a construction method that cannot deal with the problem of aging.

In addition, in practice, the upper surface of the slab concrete is not necessarily finished uniformly, and uneven portions are left, so that mud and sludge are likely to stay in these uneven portions, which act as flow-over resistance. Reduce the drainage function. It is necessary to remove mud etc. to recover drainage performance, but since the upper opening of the gutter body is narrow, work is not easy and it takes a long time, and it is often left in the middle of a halfway It is also unsanitary.

[0011]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to enable finishing as planned, whether horizontal or inclined, and to expel the use of ready-mixed concrete, mortar, etc. from the site. However, it is to provide a gutter that can significantly improve the workability of laying, shorten the number of work days and ease traffic restrictions, and can reliably realize labor saving without being affected by the weather. . In addition, it is to further improve safety by eliminating the work of hanging the lid on site.
