1 概述人字闸是一种用预制的钢筋混凝土人字架安插到闸底板预留槽内、浇筑二期混凝土使之和底板形成一个刚性整体,以人字架做支撑,以预制的钢筋混凝土平板倾斜叠放在人字架前做挡水面板组合而成的新型拦水闸。人字闸结构简单,施工方便,运行轻便灵活,人工安卸闸门板,造价低廉,仅相当于同等规模常规节制闸投资的14%。人字闸可在汛前完全拆除挡水面板,汛末再依次安放挡水面板以拦蓄降水,非汛期蓄水高度可根据需要人为控制,不仅不影响主汛期河道正常行洪,又能拦蓄非汛期及汛末降水,以涵养水
1 Overview The Mudzha gate is a kind of prefabricated reinforced concrete herringbone rack inserted into the reserved groove of the gate floor. The second phase of concrete is poured to form a rigid integral body with the floor, supported by a herringbone frame, prefabricated reinforced concrete Flat slant stacked in front of the herringbone frame to do a combination of a new water gate. The Miazidan has the advantages of simple structure, convenient construction, light and flexible operation, easy installation and removal of the gate plate, low cost and equivalent to only 14% of the investment of the conventional control gate of the same scale. Miter gate can be completely demolished before the flood in the flood control panel, and then in order to block the end of the flood season to block the precipitation, non-flood water level can be artificially controlled according to need, not only does not affect the main flood season flood, but also non-storage Flood season and the end of the flood season to conserve water
