閘框是閘板的支承構件，也是閘板的運行滑道，由地腳螺栓安裝固定在水閘閘墩及閘底板的二期混凝土中，將閘板所承受的全部水壓力安全傳遞到閘室中。為科學合理節約材料及減輕自重，其斷面制成格構式，斷面尺寸按所受荷載大小和閘板運行情況綜合考慮。閘板是用來封閉和開啟孔 口的活動擋水構件， 板面四周設鑄鐵邊框梁 ， 為提高閘板的強度 ， 板面制成拱形， 拱的圓心角按 6 0 度設計，以降低其所受的水壓力。為便于制造、 運輸和安裝 ， 閘板可制成上下幾部分 ，待到安裝現場后再用螺栓連接組裝成整體 ，連接處上下板設置法蘭和筋板使其成為閘板的中間橫梁， 以提高閘板的縱向剛度 ， 在寬度方向設置縱向筋板 ，以提高其橫向剛度，同時起到縱梁的作用。
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.

閘板是直接承受水壓力的擋水構件， 閘框是閘板四周的支承構件， 同時也是閘板上下運動的滑道， 滑道以外部分鑲嵌于閘墩及閘底的二期混凝土中， 將閘板所承受的水壓力均勻地傳遞到閘墩及閘室底部。閘框迎水面四周與閘板框四周背水面接觸處經機械精制、 加工   刨光后平直光滑、 貼合嚴密， 使結合面、 止水面與運動滑道合三為一。在啟閉機作用下， 當閘門啟閉運行時， 緊閉斜鐵和閘框滑道確保閘門的縱橫運行軌跡， 在水壓力和緊閉斜鐵的雙重作用下， 確保閘板運行平穩 ， 使閘板與閘框滑道緊密貼合， 從而達到有效止水的目的。
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.
