Abstract

PROBLEM TO BE SOLVED: To prevent floating of a channel by placing a precast open channel having an opening part on a bottom base of which a reinforcing bar is exposed on a cast-in-place reinforced concrete foundation on an upper surface of which a connecting reinforcing bar is erected and integrating them with concrete. SOLUTION: A foundation 4 constructed by erecting a connecting reinforcing bar 5 is formed of cast-in-place reinforced concrete at the time of constructing a channel for agricultural water, 1a rain water drainage channel, etc., at a place high in a ground water level. While, a rectangular opening part is provided on a bottom base of a precast reinforcing bar concrete open channel 1 (U- groove), and reinforcing bars 3 arranged vertically and laterally as reinforcing bars of the bottom base are exposed on the opening part. This reinforcing bar concrete open channel 1 is hung down on the reinforcing bar concrete foundation 4, and after the connecting reinforcing bar 5 of the foundation 4 is bent and connected to the bottom base reinforcing bar 3, concrete 6 is deposited and the open channel 1 and the foundation 4 are integrated. Thereafter, the open channel blocks 1 are sequentially connected to each other on the foundation 4, an open water channel is constructed, and it is devised not to float by ground water. Consequently, it is possible to reduce construction cost.

2. Description of the Related Art Agricultural waterways and the like are often constructed as open channels, and are often constructed in places with high groundwater levels. Therefore, when the water level in the open channel lowers, the open channel is likely to float. In order to prevent the floating of the open channel, (1) a through hole with a check valve is provided on the side wall of the open channel, and the groundwater outside the open channel flows into the open channel to keep the water level in the open channel constant. (2) The method of covering the open channel with a precast reinforced concrete lid and resisting the buoyancy of groundwater by the weight of the lid is generally adopted.

In the conventional method (1), since a large amount of water flows compared to the flow rate of the water that should flow through the open channel because the groundwater outside the open channel mixes with the water in the open channel. Not only is it necessary to use a large open channel that can handle the open channel, but it is not possible to maintain the original water quality of the water to flow through the open channel. Since it is covered with a lid, not only the construction cost becomes high, but also the problem that the monitoring and maintenance of the water channel cannot be sufficiently performed remains.
