Description

[Detailed description of the invention] The present invention relates to an assembled waterway, and can be constructed in accordance with the planned running water slope, especially in places with almost no slope or steep slopes.

It is ideal for use as a so-called variable slope waterway, and not only does it have almost uniform structural strength as a waterway, but it also easily moves laterally due to rolling pressure after construction, uneven earth pressure, etc. This was done with the aim of providing something that would never happen before, and its gist is that a hole is provided in the bottom plate of the waterway body, which has a U-shaped cross section, and the reinforcing bars placed inside the waterway body are exposed in the hole. Then, this water channel body is connected and laid on the foundation, and a reinforcing material is protruded from the foundation by being located in the above-mentioned hole, and cast-in-place concrete is poured into the bottom plate part to interpose the reinforcing material. This is an assembled waterway characterized by the fact that the main body of the waterway and the foundation are integrated.

Hereinafter, the present invention will be explained in detail based on the illustrated embodiment. In the figure, 1 is a water channel main body, which is formed into a U-shaped cross section by side plate parts 2, 2 and a bottom plate part 3,
Two rectangular punch holes 4, 4 are bored in the bottom plate portion 3.

Of course, the number and shape of the punch holes 4, 4 can be arbitrarily selected.

Further, inside the water channel main body 1, vertical bars 5, 5... and horizontal bars 6, 6... for reinforcing it are arranged so as to be perpendicular to each other, and the lower corners of the horizontal bars 6, 6... are diagonal bars. 7, 7... is reinforced.

The vertical stripes 5, 5... and the horizontal stripes 6, 6... are exposed to the outside in the punched holes 4, 4, and the longitudinal strip exposed portions 5a, 5a... and the horizontal strip exposed portions 6a, 6a...
In this way, this vertical striped exposed portion 5a,
5a... and exposed transverse reinforcement parts 6a, 6a... are arranged in the cast-in-place concrete 12 as described below to prevent a decrease in strength there and to equalize the structural strength of the waterway.

In addition, 8 and 8 are step parts 9 and 9 for lid plate mounting are joint grooves.

Reference numeral 10 denotes a foundation, which is made of foundation concrete, and can be formed with unevenness on its upper surface to improve the integration described below, or can be formed by laying a layer of chestnut stone or the like and leveling it out.

11, 11... are rod-shaped reinforcing materials, which are attached to the foundation 10 above.
When the water channel main body 1, 1... is placed on top of this, the lower half thereof is buried and protruded at the position corresponding to the punched hole 4, 4..., and the foundation 10 and the cast-in-place It is intended to be interposed between the concrete 12 and integrate the two.

The cast-in-place concrete 12 is used to connect and lay the channel bodies 1, 1,... on the foundation 10, and then pour it into the bottom plate parts 3, 3... to close the holes 4, 4... , the vertical striped exposed portions 5a, 5a
... and the horizontal reinforcement exposed portions 6a, 6a... are reinforced by reinforcement to prevent a decrease in strength here and to equalize the strength of the waterway, and the waterway bodies 1, 1... and the foundation 10 are reinforced with reinforcing material. 11, 11... are interposed to integrate the two, and when uneven pressure such as rolling pressure after construction or unevenly distributed earth pressure acts on the waterway main body 1, 1..., it can be prevented from moving laterally. It is to prevent it.

Further, as shown in Fig. 4, water channel bodies 1, 1... of different heights are laid to provide a step, and the surface 12a of the cast-in-place concrete 12 is leveled to form an inclined surface that matches the flow gradient. You can also do it.

In addition, 13 is a concrete lid body, and 14 is a grating.

Next, a construction example of the present invention will be explained.

First, the foundation 10 is formed in a straight line along the planned waterway, and reinforcing members 11, 11, . . . are provided protrudingly at predetermined locations.

Note that the water channel bodies 1, 1, which have different heights during this time...
If you use one, provide a step accordingly.

Then, the water channel bodies 1, 1... are sequentially placed and connected thereon, and the joint grooves 9, 9... are filled with joints.

Next, cast-in-place concrete 12 such as ready-mixed concrete is poured from above, and the cast-in-place concrete 12 closes the holes 4, 4, etc. of the water channel bodies 1, 1, and is integrated with the foundation 10. The upper surface of the concrete 12 is leveled as an inclined surface according to the gradient of the flowing water, if necessary.

Concrete lids 13, 13... and, if necessary, gratings 14, 14... are then placed on the upper surfaces of the channel bodies 1, 1... to cover them.

For example, a third
When unevenly distributed earth pressure acts as shown in the figure, that is, when active earth pressure Pa and passive earth pressure Pp, Pa＞
Pp, reinforcing materials 11, 11 as described above.
By integrating the waterway main body 1 and the foundation 10 with the interposition of..., the shear force Pa-
A resistance Pf is generated corresponding to Pp, and this partial pressure Pa−Pp
Therefore, the water channel main body 1 does not easily move laterally.

This applies rolling pressure to the side of the waterway, and the main body of the waterway 1
The same applies when strong pressure is applied only to one side plate portion 2.

In addition, in this proposal, when the waterway main body 1 is laid, the exposed reinforcing bars 5a, 6a in the hole part and the reinforcing material 11 may be fixed by welding, wire connection, etc.
In this case, the integration between the foundation and the main body of the waterway is further improved.

Since the present invention has the above-mentioned configuration, the holes 4, 4... of the water channel bodies 1, 1... are formed by exposing the longitudinal strips 5a,
5a... and exposed transverse reinforcement parts 6a, 6a... are filled with cast-in-place concrete 12 with reinforcement, thereby preventing a decrease in strength due to the provision of these punch holes 4, 4..., and improving the structural strength of the waterway. It is possible to achieve uniformity, and also the waterway main body 1, 1... and the foundation 1
0 is integrated with the reinforcing materials 11, 11... and cast-in-place concrete 12, so the lateral movement of the water channel bodies 1, 1... is prevented, and for example, it can be prevented from moving to one side of the water channel like a roadside ditch. When applying pressure or when receiving unevenly distributed earth pressure as a so-called retaining wall with a waterway, there is no possibility of lateral movement and misalignment of a part of the waterway.

Furthermore, the surface 12a of the cast-in-place concrete 12
can be made into an inclined surface to match the gradient of the flowing water,
In this case, there are various effects such as being able to easily and quickly form a so-called variable slope irrigation waterway having the above-mentioned effects.
