一、概况我县车口公社南峰坑水库大菲头渡槽建于一九八一年,全长258米,设计灌溉流量0.5秒立米,系钢丝网水泥U形薄壳梁式渡槽。槽身节长10米,槽顶宽1米,高70厘米,重1.643吨,槽间接缝采用聚氯乙烯胶泥止水。支承架为钢筋混凝土单排架,最大高度13.3米,重8.8吨。全槽计槽身26节,排架25根,均在现场预制,并用简易木扒杆吊装。采用这种简易吊装方法,具有设备简单,群众易于掌握;不需要电能和燃料;不受地形条件的限制,能横穿公路、溪沟,甚至上山坡也能进行;对吊装准备工作要求不高,只要地面略加平整,利用杆底
I. Introduction The Nanfukeng Reservoir in the county commune commune, the Grand Fentou Aqueduct, was built in 1981 with a total length of 258 meters. It is designed with an irrigation flow rate of 0.5 seconds and is made of wire mesh cement U-shaped thin-shell beam aqueduct. Groove length of 10 meters, 1 meter wide at the top, 70 cm high, weighing 1.643 tons, the joints between the joints using PVC plastic sealing. Supports for the single-rack reinforced concrete, the maximum height of 13.3 meters, weighing 8.8 tons. Groove total groove 26 sections, 25 shelves, are prefabricated in the field, and with a simple wood-stripping pole hoisting. The simple lifting method has the advantages of simple equipment and easy mass control; does not require electric energy and fuel; can not be restricted by the terrain conditions and can cross the highway, the creek ditch and even on the hillside; and does not require hoisting preparations As long as the ground a little flat, the use of the bottom of the pole
