闸框是闸板的支承构件，也是闸板的运行滑道，由地脚螺栓安装固定在水闸闸墩及闸底板的二期混凝土中，将闸板所承受的全部水压力安全传递到闸室中。为科学合理节约材料及减轻自重，其断面制成格构式，断面尺寸按所受荷载大小和闸板运行情况综合考虑。闸板是用来封闭和开启孔 口的活动挡水构件， 板面四周设铸铁边框梁 ， 为提高闸板的强度 ， 板面制成拱形， 拱的圆心角按 6 0 度设计，以降低其所受的水压力。为便于制造、 运输和安装 ， 闸板可制成上下几部分 ，待到安装现场后再用螺栓连接组装成整体 ，连接处上下板设置法兰和筋板使其成为闸板的中间横梁， 以提高闸板的纵向刚度 ， 在宽度方向设置纵向筋板 ，以提高其横向刚度，同时起到纵梁的作用。
The gate frame is the supporting component of the gate and also the running slide of the gate. It is installed and fixed in the second phase concrete of the water gate pier and gate bottom plate by anchor bolts, safely transmitting all the water pressure borne by the gate to the gate chamber. In order to scientifically and reasonably save materials and reduce self weight, the section is made into a lattice structure, and the section size is comprehensively considered based on the size of the load and the operation of the gate. A gate is a movable water blocking component used to close and open the orifice. Cast iron frame beams are installed around the gate surface to improve its strength. The gate surface is arched, and the center angle of the arch is designed at 60 degrees to reduce the water pressure it is subjected to. For the convenience of manufacturing, transportation, and installation, the gate can be made into upper and lower parts. After arriving at the installation site, it can be assembled into a whole by bolt connection. The upper and lower plates at the connection are equipped with flanges and rib plates to become the middle crossbeam of the gate, in order to improve the longitudinal stiffness of the gate. Longitudinal rib plates are set in the width direction to improve its transverse stiffness and also serve as longitudinal beams.

闸板是直接承受水压力的挡水构件， 闸框是闸板四周的支承构件， 同时也是闸板上下运动的滑道， 滑道以外部分镶嵌于闸墩及闸底的二期混凝土中， 将闸板所承受的水压力均匀地传递到闸墩及闸室底部。闸框迎水面四周与闸板框四周背水面接触处经机械精制、 加工 刨光后平直光滑、 贴合严密， 使结合面、 止水面与运动滑道合三为一。在启闭机作用下， 当闸门启闭运行时， 紧闭斜铁和闸框滑道确保闸门的纵横运行轨迹， 在水压力和紧闭斜铁的双重作用下， 确保闸板运行平稳 ， 使闸板与闸框滑道紧密贴合， 从而达到有效止水的目的。
The gate plate is a water blocking component that directly bears water pressure. The gate frame is a supporting component around the gate plate, and it is also a slide for the up and down movement of the gate plate. The outer part of the slide is embedded in the second phase concrete of the gate pier and the gate bottom, evenly transmitting the water pressure borne by the gate plate to the bottom of the gate pier and the gate chamber. The contact area between the upstream surface of the gate frame and the downstream surface of the gate frame is mechanically refined, processed, and polished to be straight, smooth, and tightly adhered, so that the joint surface, stop surface, and motion slide are combined into one. Under the action of the hoist, when the gate is opened and closed, the tightly closed inclined iron and the gate frame slide ensure the longitudinal and transverse running trajectory of the gate. Under the dual action of water pressure and tightly closed inclined iron, it ensures the smooth operation of the gate, making the gate closely adhere to the gate frame slide, thereby achieving the purpose of effective water stopping.
