overflow weir 越水堰,漫壩。

overflowing

From roundwood reservoir in county wicklow of a cubic capacity of 2 , 400 million gallons , percolating through a subterranean aqueduct of filter mains of single and double pipeage constructed at an initial plant cost of 5 per linear yard by way of the dargle , rathdown , glen of the downs and callowhill to the 26 acre reservoir at stillorgan , a distance of 22 statute miles , and thence , through a system of relieving tanks , by a gradient of 250 feet to the city boundary at eustace bridge , upper leeson street , though from prolonged summer drouth and daily supply of 12 1 2 million gallons the water had fallen below the sill of the overflow weir for which reason the borough surveyor and waterworks engineer , mr spencer harty , c . e . , on the instructions of the waterworks committee , had prohibited the use of municipal water for purposes other than those of consumption envisaging the possibility of recourse being had to the importable water of the grand and royal canals as in 1893 particularly as the south dublin guardians , notwithstanding their ration of 15 gallons per day per pauper supplied through a 6 inch meter , had been convicted of a wastage of 20 , 000 gallons per night by a reading of their meter on the affirmation of the law agent of the corporation , mr ignatius rice , solicitor , thereby acting to the detriment of another section of the public , selfsupporting taxpayers , solvent , sound 但是由于夏季久旱,再加上每天供水一千二百五十萬加侖,水位已降到低于排水口。都市監察官兼水道局技官土木工程師斯潘塞哈蒂奉水道局的指示鑒于有可能會像一八九三年那樣被迫利用大運河和皇家運河那不宜飲用的水,除了飲用外,下令一律禁止使用市里供應的自來水。尤其是南都柏林濟貧院,盡管限定用六英寸的計量器,每個貧民每日配給十五加侖水,然而在市政府法律顧問辯護律師伊格內修斯賴斯的監督下,經查表證實,每夜要浪費兩萬加侖水,從而使院外的社會各階層也就是自費并有支付能力的納稅者們蒙受損害。

The analysis show that the project target of detaining the coarse and discharging the fine can be got with the related measures , such as placement of the warping sluice on the concave bank of a bending reach ; arrangement of the overflow weir on a bending reach and reasonable zoning and scientific control of the desilting channels etc 分析表明,采用將放淤閘布設在彎道上段的凹岸、彎道設置溢流堰、淤沙條渠的合理分區和科學調度等措施,可以實現試驗工程淤粗排細的目標。

According to the hydraulic property of overflow weirs under steady flow , the flow patterns of overflow weirs were classified into free overfall and submerged overfall , and numerical models for unsteady flow were established to simulate the two flow patterns respectively 摘要為了對保水堰的交替水流進行數值模擬,依據保水堰恒定流情況下的工作特性,將保水堰的水流形態分成堰流和滿流兩種狀態,分別建立保水堰不同流態下的非恒定流數學模型。

This paper introduces the surface forming technology for pocket concrete overflow weir , analyzes and compares construction technique for two types of gate and built - in parts , and presents rating methods for concrete samples when they are less than 30 groups 摘要現介紹了小型混凝土溢流堰堰面成型工藝,分析比較了兩種閘門埋件施工工藝,提出了數量不足30組時的混凝土試塊評優的方法。
