落差建筑物
drop structure
Iuoeha Jianzhuwu落差建筑物(drop structure)架道通过地面落差集中或坡度过陡地段时所修建的建筑物。它的作用是:①渠道通过地面坡度过陡地段时,为了保证染道的设计纵坡而将渠底高程的落差适当集中,在落差集中处修建连接上下游渠道的联接建筑物‘②在干支渠分水处,如二者高差较大时,修建两级渠道的联接建筑物。③在“长藤结瓜式”水利系统(见长藤结瓜式灌溉网)中,当水库水位变化较大,其最高水位又低于渠底高程时,修建染库的联接建筑物。④修建架道上排洪、退水、泄水建筑物,并普遍用于河岸溢洪道的泄槽 落差建筑物的主要类型有陡坡、跌水、斜管式跌水及跌井等。此外,还有悬臂式跌水、格栅式跌水、箱式跌水等特殊型式。陡坡与跌水应用最广泛。根据落差大小,二者又有单级和多级的布置形式。斜管式跌水的特点是把陡坡部分用倾斜压力暗管代替,较经济,但适应的流量及跌差范围均较小。跌井又称直落式跌井或井式跌水,其型式与井式溢洪道类似,特点是工程范围较小,适应的跌差较大。落差建筑物的型式选择应根据当地具体情况及技术经济条件确定。通常主要决定于地形、落差、流量等因素。 落差建筑物设计的主要要求是:保证建筑物本身及与之连接的上下游渠道有良好的水力条件;进口前不得出现较大的水面降落或奎高现象,以免上游渠道产生冲刷或淤积:出口须设消能防冲设施,充分消能,以免造成下游冲刷;建筑物本身须满足强度与稳定要求;工程量省;施工管理方便;工程安全可靠。
