摘要(英) |
At present in water-supply areas, as for the supply nets of piped water, there are still plenty of problems on operation, maintenance, and administration, including water pressure, water quantity, and water quality. While the supply nets of water lack of water to provide, or the broken pipes and other causes lead water supply unbalanced, which will show the importance of the water-control devices —like water bolts and water-supply operation. In case there are too many such bolts, the cost of the construction and the manpower of administration will surely increase uselessly. In other respects, should the water-control bolts are deployed deficiently, many water bolts must be switched off as the pipes are broken and need to be repaired in time. If the bolt is installed in the wrong place, the broken pipe will cause the water supply unbalance.
When the system of the supply-water pipes leaking, the water pressure will be low in the water-supply area, the quantity of water supply will reduce, and the quality of water will be also polluted. In the period of switching off the broken pipes, the neighboring water bolts are waiting to be repaired in order to supply water. During the recondition of water supply, the flow and the direction of each pipe section, and surplus water ends of each joint will face unbalanced condition. Probably it will make the water pressure of the joints lower. Then the proper water pressure could not be satisfied (1.5~4.0kg/ cm2) when providing the customers running water. The study uses Hardy Cross method to analyze each section when pipes are broken. Through installing the water-control bolts, increasing or decreasing the volume of water supply, increasing or decreasing the areas of water supply, dividing the districts and times of water supply, and probing various angles to analyze the matter, an engineer can improve the balance of water supply more precisely.
This study bases on the water supply of Yu-shih district, through analyses and synthetic arrangements; we propose the improvement plans which provide the references for how to install water-control bolts and how to maintain and administrate water supply for the future is proposed. In addition, by applying flow meters , piezo-meters, and the center of monitor, which will facilitate to switch off bolts in case of any broken pipes, so it may shorten the repairing time for water supply and maintain water supply steadily during the period of fixing. |
