DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable slope type gutter for draining rainwater or miscellaneous drainage, or an ordinary cover type gutter .

[0002]

2. Description of the Related Art In order to eliminate rainwater at an early stage, a bottom plate of a gutter body which is joined in series and forms a gutter is formed so as to be inclined downward from an upstream end to a downstream end, and the slope is formed. What is necessary is just to secure a required water conveyance gradient along the length direction. In the variable slope type gutter disclosed in Japanese Utility Model Publication No. 56-51113, the upper part of the left and right side plates of the gutter body is connected by horizontal beams at the front and rear ends, and the lower part of the left and right bottom slabs is fully open. At the laying site, the bottom slab concrete is cast according to the gradient of water conveyance.

[0003] In the procedure for constructing the variable slope type gutter, foundation rock is laid on the bottom of a ground excavation groove, tamped with a rammer or the like, and then, at a later date, foundation concrete is poured by a ready-mixed concrete vehicle. After the foundation concrete has hardened to a predetermined strength, a predetermined number of gutter main bodies are sequentially laid, bottom slab concrete is poured from the upper opening of the gutter main body, and leveling is performed according to the design water conveyance gradient.

The upper part is entirely or partially opened, and the bottom plate part
Are formed integrally with the left and right side plate parts.
In the construction procedure, foundation stones are laid at the bottom of the excavation trench in the ground, tamped with a rammer, etc., and then, at a later date, foundation concrete is poured by a ready-mixed concrete vehicle. After the foundation concrete has hardened to a predetermined strength, a predetermined number of gutter main bodies are sequentially laid, bottom slab concrete is poured from the upper opening of the gutter main body, and leveling is performed according to the design water conveyance gradient.

[0005] However, in this variable slope type side groove,
There are many processes, such as compacting the foundation rock, placing the foundation concrete, placing the bottom slab concrete, and leveling, resulting in a problem that the overall construction period is long. In addition, since it takes a lot of time to process concrete from a ready-mixed concrete car, traffic obstruction such as road closure or one-sided traffic is given for a long time. The inability to allow water to flow immediately after placing the bottom slab concrete is another factor that hinders the shortening of the process. Slab concrete
Except for installation and leveling, the same problem occurs with the normal cover type gutter.
There is.

[0006] Further, in the case of the variable slope type gutter , the work efficiency is poor because the casting and leveling of the bottom slab concrete must be performed from a relatively narrow opening of the gutter main body. It takes a lot of time to complete the slope according to the designed headrace gradient. In reality, it is impossible to achieve the slope and finish as designed.

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

[0008] This is usually 10 to 50 products of the same height
More than one is laid in the longitudinal direction, for example, product length 2m
It is not possible to take a 5% gradient for 10 products, i.e. 20 m long. That is, the terminal has a height of 1 m. Therefore, with a 20m laying and a 10cm drop, 0.5
% Slope is not quite possible. It is practically impossible to finish a 10 cm drop with a 20 m extension.

If the method as shown in FIG. 17 is carried out, the gradients are 5% for a standard depth difference of 10 cm and 10% for a 20 cm difference. It is. It can be said that the finishing of the horizontal portion is not practically possible as designed. Due to the inaccurate finishing, it is pointed out in many cases that the required flow speed and water flow rate are not obtained.

[0010] Furthermore, foundation rock, foundation concrete,
All the processes related to bottom slab concrete depend on humans.In addition, as mentioned above, each process is interrupted every time, and it is carried out in small pieces. It is a construction method that cannot respond to the problem of aging.

Also, in practice, the upper surface of the bottom slab concrete is not always finished uniformly, leaving irregularities. Mud and sludge tend to stay in these irregularities, and these act as flow resistance. And reduce the drainage function. To recover the drainage performance, it is necessary to remove mud, etc., but since the upper opening of the gutter main body is narrow, work is not easy and it takes a long time and it is often left halfway, so bad odor It is also unsanitary.

[0012]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to finish as planned, whether horizontal or graded, and to expel any use of ready-mixed concrete or mortar from the site. In addition, it is possible to greatly improve the workability of laying, shorten the construction days and ease traffic regulations, and realize a variable slope type or ordinary cover that can realize labor saving of construction without being affected by the weather. It is to provide a mold groove . Another object of the present invention is to further improve safety by eliminating the need for a lid-covering operation on site.

However, in the case of clay soil, the base concrete 21 can be laid directly. In FIG. 1, no sand 20 is laid on the lower surface of the base concrete slab 21, and in the embodiment of FIG. 5, sand 20 is laid.

FIGS. 9 to 16 show an embodiment showing a method of supporting the bottom plate 12. FIG. In the supporting method shown in FIGS. 9 to 11, fixing members 27 and 28 made of nut-type inserts are embedded and fixed to the side plates 6 and 6 of the side groove main body 1. Elongated holes 31 and 32 in the height direction are provided in the vertical plate portions 29 and 30 of the support members 25 and 26 made of L-shaped metal plates. The fixing members 23 and 24 composed of bolts are used for the eccentric seat plate 3.
The fixing members 27 and 28 are screwed into the fixing members 27 and 28 through the eccentric shaft holes 35 and 36 of the holes 3 and 34 and the slots 31 and 32.

The periphery of the eccentric seat 33 is brought into contact with a stopper projection 37 on the upper end of the vertical plate 29 and a horizontal plate 38, and the support member 2 is moved along the elongated hole 31 by the rotation of the eccentric seat 33.
After adjusting the height position of 5, the fixing member 23 is tightened. Similarly, the peripheral surface of the eccentric seat 34 contacts the stopper projection 39 of the vertical plate 30 and the horizontal plate 40. Bottom plate 12
Left and right ends of the horizontal members 38, 4 of the support members 25, 26
0 and is stably engaged with the support members 25 and 26 by its own weight.

The bottom plate 12 placed on the horizontal plate portions 38, 40 of the support members 25, 26 in this manner can be easily attached and detached, and the bottom plate 12 can be cleaned with the bottom plate 12 removed as necessary. Work can be performed efficiently and accurately.
The inclination angle of the bottom plate 12 is finely adjusted by rotating and tightening the eccentric seat plates 33 and 34 so as to match or approach as close as possible the design water conveyance gradient.

In order to stably support the bottom plate 12 with the support members 25, 26, the horizontal plate portions 39, 40 of the support members 25, 26 are required.
May be brought into contact with the lower surfaces of the left and right ends of the bottom plate 12 with as wide a width as possible. In order to secure this wide and stable contact state, as shown in FIG. 11, the supporting members 25 and 26 are appropriately rotated around the fixing members 23 and 24 so as to correspond to the water introduction gradient, and then the side plates 6 and 6 and fix it.

Reference numeral 42a is bent inward and abuts on the upper surface of the bottom plate 12 to prevent the bottom plate 12 from rising. When it is necessary to remove the bottom plate 12, the upper ends 41a, 42a of the holding plates 41, 42 may be bent back to release the restraint by the holding plates 41, 42.

As a method of adjusting the inclination angle of the bottom plate 12 by changing the mounting positions of the support members 25 and 26, a plurality of eccentric seat plates 33 and 34 are used instead of a plurality of rotation systems as shown in FIG. The fixing members 27 and 28 can be embedded and fixed on the same straight line with their heights shifted, and one of them can be selected to fix the fixing members 23 and 24 to the side plates 6 and 6.

The setting method of the inclination angle of the bottom plate 12 is as follows.
Instead of embedding the fixing member in the side plate in advance, fixing members 23 and 2 made of concrete nails as shown in FIG.
4, the fixing through-holes 29a for the vertical plate portions 29, 30 are used.
The fixing members 23 and 24 pass through the support members 25 and 30a.
It is also possible to strike 26 at a predetermined height position measured on the side plate 6.

Further, as shown in FIG.
It is also possible to fix the support members 25, 26 at predetermined measured positions of the side plate 6 by using pre-attached or post-punched anchor bolts as 3, 3.

The bottom plate 12 is supported by the above-described method. At this time, a gap 45 is formed between the concave portion 6 on the inner surface of the side plate and the bottom plate 12. As a method of filling the gap 45,
As shown in FIG. 10 and FIG. 12, a method of filling the gap 45 with the water rubber 43 or mortar, or a method of stopping water by providing the convex portion 47 on the bottom plate as shown in FIG. is there.

In the laying example shown in FIG. 17, 10 to 50 or more products of the same height are arranged in the longitudinal direction, and
This is an example in which the product is laid using a product having a gradient of 5% in cm. With this method, as is traditionally done,
Finishing on site is possible, but width 30cm-60cm
Gradient finishing in the work space requires a great deal of effort and is not efficient.

[0033] When applied using variable gradient type groove in the example of FIG. 17, work efficiency is improved, the variable
If the advantage of the slope type side groove is utilized, it is possible to lay as shown in FIG. In other words, one product with a length of 2 m
Zero lines are arranged in the longitudinal direction to make a total length of 20 m, and precise finishing such as taking a gradient of 0.5% with a standard height difference of 10 cm becomes possible.
