Abstract

PROBLEM TO BE SOLVED: To make it possible to supply water when water is required in an emergency by arranging water storage tanks in parallel in spaces at both the sides of an arch of a reinforced concrete bridge with the arch located at the center and by storing a constant amount of water by the natural water supply and drain. SOLUTION: Water upstream of a valley conveyed from a conduit 11 by the principle of siphon is stored in a water storage tank 5, and excess water exceeding a constant volume of water storage is overflowed from a drain pipe 12 and drained to a river course. When water is needed in an emergency such as a fire, a manhole 7 is opened and water is taken out from an intake hole 6a and used and, at the same time, water can be naturally taken in from a supply cock. In this case, a water storage tank 5 is arranged in parallel, and the bridge 1 and storage tank 5 are made as a structure in one united body, thereby achieving the purposes of both the bridge 1 and water storage tank 5. By doing so, power and energy are made unnecessary, and a constant volume of water can be stored naturally for quickly responding to a natural calamity or a disaster caused by human neglect.

In the transportation industry, especially in automobiles, the growth is remarkable, and the roads required for traveling have been enriched. The roads are also set up in a mountain network, and various bridges are being built up to large and small rivers and valleys as well as small drainage channels. Currently, reinforced concrete bridges spanning rivers and valleys (swamps) have an arch in the center and quarry is embedded in the space on both sides of the arch to eliminate the space and make it a bridge.

If an emergency such as a natural disaster or man-made disaster occurs and water is needed, for example, a fire occurs when a house collapses and water supply and electricity are stopped as in the Great Hanshin Earthquake, and water is needed for fire extinguishing or for daily life Even if it becomes, it can not respond immediately, and the period until the restoration of electricity and water must be spent in a difficult state. In this way, even on flat terrain, the response is much slower in the mountainous areas, and many related problems arise.

Then, if water is needed in the event of fire, irrigation, or other emergencies, a manhole is opened and water is taken out from the extraction hole and used. After use, if the extraction hole is covered with a manhole, water will be supplied to the water tank again and stored. If necessary, a small filtering device or a circulating device may be provided in the water storage tank so as to circulate the water slowly and prevent water rot. In addition, when conducting water from the valley river, water is supplied by a conduit using the siphon principle so that even a small amount of earth and sand will not enter the water storage tank.
