水电站防汛预案

Do the following three main points: 1 find out the weak. Review process is to sum up the knowledge on the one hand, make the knowledge more coherent system and regularity, but also let the students themselves, looks up the deficiencies. So, we teachers to understand the students knowledge of the situation prior to the review, students not only found widespread deficiencies, but also some shortcomings, for these well designed programs, reasonable arrangement of time, this review is more targeted and more effective. For example, you can design a form for investigation, understanding students weaknesses in each knowledge, put it as a review of key, combined with the problem of textbooks to review, both to avoid casting a net tihaizhanshu, and improve the efficiency of review. 2, good collation. Through six years of study, students in the basics, reading method, exercises, and so already have a certain degree of accumulation, the review stage, teachers should know how to guide the students to label the accumulation, process, form a system of knowledge networks. Exercises for students to be representative, fine, complete, to live, and earnestly do a problem learning a method, class of pass was to get time efficient review results. 3, pay attention to use. The accumulation of knowledge is ultimately to use, therefore, review the situation and life situation to be created in a variety of languages, guide students on the basis of the previous accumulation of knowledge to use to the maximum, and really apply what they have learned. Second, review the content and strategy of the first part: the basics (a) 1, review the main points of Hanyu Pinyin is able to recite and write down the alphabet of Hanyu Pinyin; accurate spelling pronunciation (after reading cacuminal, nasal sound, light, and retroflex sounds), the correct write consonants, vowels and syllables. 2,. main types according to the order of the alphabet of Hanyu Pinyin alphabetical order; fill in the appropriate uppercase and lowercase letters; see phonetic writing words; pinyin to write sentences with dot to select the correct pronunciation of the word; to bring some initial consonants or vowels, word selection. Second, the main types of words (1) Ruby written words; (2) to bring Word to select the correct pronunciation; (3) use a sequencer and radical character lookup method德溪电厂防汛预案 为贯彻“安全第一，常抓不懈，以防为主，全力抢险”的防汛方针，根据德溪电厂水工建筑物及其防汛设施的运行情况，合理科学地进行水库调度，确保水库电站安全渡汛，减轻上下游洪水造成的损失，特制定防汛抗洪预案如下：一、 基本情况电站为于高安镇下游9公里处，水库集雨面积174.2平方公里，多年平均降雨量1892.1毫米，设计总库容450万平方米，水库正常水位256.7米，设计洪水位258.73米，调节库容175万平方米，属不完全调节。水库库容小，无调节洪水能力，也不承担下游防汛任务。电站枢纽主要由挡水坝，压力引水洞，压力管道，厂房等组成。大坝为混凝土砌石拱坝，坝高45.7米，其溢流段坝高高程256.7米。二、 运行水位根据水库现状，水库汛期运行水位256.7米以下。三、 汛期运行调度根据洪水及天气预报，灵活地进行调度，在洪水到来之前将水位降到最低，即要确保电站本身安全和上下游防洪，又要力争在来水量少时及时蓄水，保持水位，充分发挥电站效益，这是防洪总原则。1、运行准则：根据实际情况，充分利用水电资源，合理科学的进行调度，满足电站发电需要以发电量最大为准则，发生特大洪水时以电站水库、厂房安全和上下游防洪安全为主要目标。2、防洪原则：根据运行准则，在发生洪水时兼顾发电与防洪。在汛期加强与华安气象部门联系（电话：），随时了解掌握预计降雨量和入库流量，估计洪水规模，做到合理科学地调度，在洪水来临之前尽可能降低水位，增加调库容，以减轻上下游地区淹没损失。四、 防汛抗洪措施1、组织措施：为了做好防汛抗洪工作，成立防汛领导小组，负责研究部署抗洪人力组织，部署、检查、落实防洪计划，加强领导统一指挥。 防汛抗洪领导小组：组长副组长：现场负责人：成 员：2、在防汛抗洪领导小组的领导下，全体动员，各岗位密切配合，组织抗洪抢险小组，落实任务，分工负责，做到人人有则，各负其则，汛前进行必要的防洪演习。做到在系统停电的情况下，能迅速恢复厂用电，保证电站的防洪防汛用电。3、汛前，做好电站水工建筑物及有关设备安全检查对存在问题及隐患，及时进行整改。汛中注意水工建筑物及有关设备的运行情况，发现异常，及时采取措施，消除隐患，切实做到水工机电设备完好，确保汛期安全运行。1) 完成厂内外水泵维护保养，运行正常，可以随时投入运行。2) 对备用潜水泵进行检查、试验，可正常使用，并准备了响应的水带。3) 水库冲沙闸做好防水措施。4) 厂区各排水沟经检查无淤堵现象。4、确保水文通讯的畅通，以保证及时准确地传递水位，降雨量等水文数据，作出洪水预报，指导防汛抗洪工作。要求手机24小时不关机。5、做好防汛物资准备，各部门提出补充防汛物资计划，由采购部门负责采购。1） 再准备200只编织袋沙5立方米用于装沙包。2） 准备雨衣矿灯用于户外、夜间巡视。3） 准备铁斗车一辆用于运沙包。4） 厂外用PVC管出水口更改为钢管，增加备用水泵的出水能力。6、加强对备用电源的维护管理，在厂用电源自身无法供电时，及时投入备用电源。柴油机组启动正常，要求值班员学会使用柴油发电机组，每月5、15、25日起动20分钟。7、加强与当地政府及上下游村委会的联系，不定期举行防汛抗洪联席会议，共商抗洪抢险大计，制定措施，统一指挥，共同将防汛抗洪工作做好。8、加强与上游电站的联系，做到人员、物资互补。五、 防汛抗洪要求1、各班水工、机电运行人员应明确岗位职责，忠于职守，站长、值长加强监督检查。2、进入汛期水工值班人员应加强与华安水文站（电话：等部门联系，及时掌握上游雨情、水情，进行洪水预计，指导当班发电运行。当日降雨量超过50mm时，应向防汛领导小组汇报，做好防汛准备。3、汛期，各运行班指派专人对水工建筑物进行巡视检查，观察水位的变化情况，发现异常，及时向防汛领导小组汇报、处理。4、运行值班人员接到有关防汛部门电讯及当值巡检发现异常情况，应及时做好记录，确定无误后向值班领导汇报，并转告有关人员。5、值班及值班轮
