(一)年鱼神桁架梁组合渡槽年鱼神渡槽(见照片1)全长181米(不包括进、出口段),最大高度23.7米,纵坡1/1000,最大流量3.5秒立米。槽身为下撑式桁架 L 形梁组合结构,每跨长24米。L 形梁既是输水构件,又是组合结构中的主要承重构件,梁壁厚10厘米;桁架拉杆为两根不等边角钢(L100×63×10)拼成;压杆为钢筋混凝土杆,截面为20×22.5平方厘米。每跨槽身由两片桁架 L 形梁拼成,桁架梁在地面平卧预制,用两台日产40吨汽车吊抬吊至墩上就位后拼装,槽墩为素混凝土空心墩,
(A) Year of the fish god truss beam aqueduct aqueduct aqueduct (see photo 1) a total length of 181 meters (excluding the import and export section), the maximum height of 23.7 meters, longitudinal slope 1/1000, the maximum flow 3.5 seconds Li. Groove body under the truss L-beam composite structure, each span length of 24 meters. The L-shaped beam is not only the water conveyance member, but also the main load-bearing member in the combined structure, the beam wall thickness is 10 cm; the truss pull rod is composed of two unequal-angle angles (L100 × 63 × 10); the press bar is a reinforced concrete bar, 20 × 22.5 cm 2. Each cross body is made up of two truss L-shaped beams. The truss girder is prefabricated on the ground. Two 40-ton Nissan crane lifts and lifts it to the pier to assemble. The slotted pier is a plain concrete hollow pier,
