(1) The working bridge is installed to facilitate the staff to operate the bridge. The height of the working bridge is related to the size and form of the gate. Because of the flat gate, the fixed hoist is used. After the gate is lifted, it cannot affect the maximum discharge flow, and there is a certain extra part. According to the work needs and design specifications, the working bridge should be directly above the working gate and used to support the working bridge.(2) The height of the working bridge depends on the form of the gate and the water surface of the gate hole. The difference between the elevation of the bottom edge of the beam of the working bridge and the elevation of the bottom edge of the breast wall when a fixed gate hoist is used for the plane gate The bottom elevation of the working bridge beam is 27m.The working bridge adopts an assembled structure, and the bridge deck is placed on two longitudinal beams. The total width of the working bridge is 3600mm. The height of the longitudinal beam of the working bridge is 800mm, the width of the longitudinal beam is 1/2 ~ 1/3 of the height, and 300; the height of the transverse beam of the working bridge is 2/3 ~ 3/4 of the longitudinal beam, 600mm, and the width is 1 / h of the height 3 ~ 1/2, take 250mm, and the thickness of theworking bridge is 100mm . The layout of the working bridge is shown in Figure 2-2.
