건설(토목)관련 구조물 해석입니다.
나름대로 아무리 해볼려고 해도 쉽게 안되네요.....
도무지 단어만 찾아가지고는 뜻이 이해가 안되고 연결도 안되고....
공학영어에 능통하신 고수님들의 도움 부탁드립니다.
1. water
- Gate valve w/box
: Gate valves may have either a single solid wedge gate or double disc. Solid wedge gates are satisfactory in sizes up to 6 inches, but double disc gates should be used for larger sizes. Because of the excessive wear and leakage of the gates and seats which may result, gate valves should not be used where frequent operation is required. If gate valves are left open for long periods, debris may accumulate in the seats and prevent complete closure, but if left closed for long periods, deposits may prevent opening. Gate valves should be operated periodically to break loose any deposits which might have formed. Large gate valves should be geared to make operation easier.
2. Sewer
- Septic tank (간이 정화조, 오물 정화조)
: Septic tanks, with appropriate effluent disposal systems, are acceptable as a treatment system for isolated buildings or for single-unit residential buildings when permitted by regulatory authority and when alternative treatment is not practical. when soil and drainage characteristics are well documented for a particular site, septic tank treatment may be permanently feasible.
Septic tanks perform settling and digestion functions and are effective in treating from 1 to 300 population equivalents of waste, but will be used only for 1 to 25 population equivalents, except when septic tanks are the most economical solution for larger populations within the above range. Minimum size will be at least 500-gallons capacity. In designing tanks, the length-to-width ratio should be between 2:1 and 3:1, and the liquid depth should be between 4 and 6 feet. Detention time depends largely on the method of effluent disposal.
When effluent is disposed of in subsurface absorption fields or leaching pits, 24 hour detention time based on average flows is required. The septic tank must be sized to provide the required detention(below the operating liquid level)for the design daily flow plus an additional 25 percent capacity for sludge storage. If secondary treatment such as a subsurface sand filter or an oxidation pond is provided, this can be reduced to 18 hours. Open sand filter treatment can further reduce detention time to 10 to 12 hours. Absorption field and leaching well disposal should normally be limited to small facilities(less than 50 population equivalents). If the total population is over 50, then more than one entirely separate field or well would be acceptable. For 10 or more population equivalents, discharge of effluent will be through dosing tanks which periodically dischaige effluent quantities near 80 percent of the absorption system capacity.
3. Water hammer(수격현상)
① Definition.(정의) : Waterhammer is sometimes called surge or transient pressure. The phenomena is caused by rapid changes in flow in closed conduits which cause pressure waves to travel through the liquid, both upstream and downstream from the point of origin.
② Causes.(원인) : The most common causes of waterhammer include rapid valve closure, starting and stopping of pumps and conduit failure. Types of valves include main lines, fire hydrant or reservoir fill. Other causes include a sudden stop in usage by a large customer or the sudden joining of a column of water that had been separated by a vacuum.
