4、潜孔式平面钢闸门2、孔口尺寸(宽×高):5.0m×5.0m3、上游水位:45m4、下游水位:0m5、闸底高程:0m6、启闭方式:电动固定式启闭机7、材料:钢结构:Q235-A.F焊条:E43型行走支承:采用滚轮支承止水橡皮:侧止水和顶止水用P型橡皮,底止水用条型橡皮8、制造条件:金属结构制造厂制造,手工电弧焊,满足Ⅲ级焊缝质量检验标准。9、规范:《水利水电工程钢闸门设计规范SL1974-2005》二、闸门结构的形式及布置文案大全实用标准1、闸门尺寸的确定闸门高度:顶止水△H=0.2m,故闸门高度5.2m闸门的荷载跨度为两止水的间距:5.0m闸门计算跨度:5+2×0.2=5.4
5、(m)设计水头:45m2、主梁的数目及形式主梁是闸门的主要受力构件,其数目主要取决于闸门的尺寸。因为闸门跨度L=5m,闸门高度h=5m,L6、定布置5道横隔板,其间距为1.24m,横隔板兼作竖直次粱。(2)纵向连接系,采用斜杆式桁架。三、面板设计根据《钢闸门设计规范S74—95》关于面板的设计,先估算面板厚度,在主梁截面选择以后再验算面板的局部弯曲与主梁整体弯曲的折算应力。1、估算面板厚度假定梁格布置尺寸如图2所示。面板厚度按下式计算t=akp(0.9ασ)文案大全实用标准当b/a≤3时,a=1.5,则t=akp(0.9×1.5×160)=0.068akp当b/a>3时,a=1.4,则t=akp(0.9×1.4×160)=0.07akp现列表1计算如下:表1区格a(mm)b(mm)b/akp[N/mm2]kpt(m7、m)191012301.350.5100.5440.52732.61291012301.350.4290.5540.48830.20391012301.350.4290.5640.49230.44491012301.350.4290.5730.49630.69591012301.350.4290.5830.50030.94691012301.350.4290.5930.50431.19791012301.350.4290.6030.50931.50891012301.350.4290.6130.5133
6、定布置5道横隔板,其间距为1.24m,横隔板兼作竖直次粱。(2)纵向连接系,采用斜杆式桁架。三、面板设计根据《钢闸门设计规范S74—95》关于面板的设计,先估算面板厚度,在主梁截面选择以后再验算面板的局部弯曲与主梁整体弯曲的折算应力。1、估算面板厚度假定梁格布置尺寸如图2所示。面板厚度按下式计算t=akp(0.9ασ)文案大全实用标准当b/a≤3时,a=1.5,则t=akp(0.9×1.5×160)=0.068akp当b/a>3时,a=1.4,则t=akp(0.9×1.4×160)=0.07akp现列表1计算如下:表1区格a(mm)b(mm)b/akp[N/mm2]kpt(m
