中文拼音 [shuǐzhákǒng]
水閘孔
英文
sluice opening-
With the further economic growth and the implement of development of the western regions, hydroelectric construction in our country is undergoing rapid growth, anumber of high - dam power - station is in building or in programming. in view of its higher - head and larger magnitude of spill structure outlet, it is difficult for conventional concrete or reinforced concrete structure of pier and pier room to support its vast water pressure. coupled with the improvement of prestressed method, it has been the noteworthy tool in solving the problem
隨著我國經濟的加速發展及西部大開發戰略的實施，我國水電事業也迎來了迅猛發展的大好時機，一批高壩水電站正在建設或規劃之中，其泄水建築物孔口及水頭愈來愈大，常規混凝土或鋼筋混凝土閘室閘墩結構難以承受如此之大的水推力作用，隨著預應力技術的成熟，這一技術已成為解決該問題的關鍵技術措施之一。A flap vlave used in pumping station is a kind of hydraulic - operated automatic gate, which is similar to a hinged check vaive. because of their simple structure and reliability, being able to shorten the length of outlet passage and facilitate the starting of pumping system in comparison with siphonic vacuum - distroied cutoff scheme. so it is propitious to be used and save investment but at the same time, flap valves always show some disadvantage
因拍門簡單、可靠，與虹吸真空破壞截流閉鎖方式相比，可以縮短出水管道（流道）長度，並利於泵系統起動，與快速閘門相比，拍門也有諸多優點，閘門門體易關閉不到位或卡住不能活動，因為門槽和?塊較軸孔容易殘留異物，閘門門體克服滑動阻力不僅無機械增益，且阻力和動力不在一直線上，門體易傾斜而自鎖，而拍門的工作可靠性則遠高於快速閘門。The different drawbacks in the original design and construction of the emergency gate slot of the releasing tunnel of zhelin hydropower station in jiangxi province resulted in the disjunction of most slot corner plates under the parapet walls of two sides of the left hole and the damage of the second - phrase concrete in these slot corner plates, after the gate is closed and under the action of seepage water pressure
江西省柘林水電站泄空洞檢修門槽，由於原設計和施工均存在不同的缺陷，致使閘門關閉后，在滲透水壓作用下，造成左孔兩側胸墻以下大部分門槽護角板被擠壓脫開，護角板裏面的二期混凝土損壞。The flow regime inside of the tunnel, the characteristics of hydrodynamic load, the hydrodynamic pressure feature at the gate slot and the vent air speed during the shutting of the gate is studied through model test, and then the reliability of the gate, the feature of the vent air speed and the pressure at the gate slot during the shutting of the gate are analyzed based on the test result concerned
通過模型試驗研究了事故閘門關閉過程中泄洪洞內的水流流態、門體的水動力荷載特性以及門槽段動水壓力特性、通氣孔風速，並根據試驗結果分析了該閘門動水下門過程中的可靠性，通氣孔風速特性和門槽段壓力特性。Abstract : this paper summarizes a series of tests and inve stigations on general layout, const ruction diversion, flood disposal, navigation, river closure, form of gate opening s ection, pattern of energy dissipation and scouring under sluice carried out for f eilaixia proj ect by the scientific research institute of prwrc during the period from 1983 to 1998 and presents their major results
文摘:綜合闡述了珠江水利委員會科學研究所從1983 ? 1998年間對飛來峽水利樞紐的整體布置、施工導流、泄洪、通航、截流、閘孔斷面形式、閘下消能形式、閘下沖刷等所進行的一系列試驗和研究工作，並介紹主要試驗研究成果。Based on structural design criterion of floodgates, a finite clement method is adopted to analyze and calculate deep - hole gate chamber. and based on space plank analysis theory, area stress is considered in the stress calculation of original laminose problems. the method is simple, convenient and manageable and reaches better precision
本文在設計規范的基礎上針對水閘的結構設計，採用有限元對深孔閘的閘室進行了分析計算，根據空間板的分析理論，在原薄板問題的受力計算基礎上考慮了閘內力的作用。Abstract : the outflow through gate controlled multi - opening spillway of yinhe reservoir was analyzed. the analysis results were checked by the site observed data
文摘:分析了音河水庫多孔有閘門控制的溢洪道出流，並用出流的實測資料進行了檢驗。分享友人
