摘 要:探讨了城市综合管廊用的几种顶进施工法钢筋混凝土拱涵的断面形式,分析了方形、圆形等混凝土拱涵的优势,设计了组合型钢筋混凝土圆拱涵。该涵体制作采用芯模振动工艺,局部采取加固措施,具有耐久性优良、劳动生产率高、现场安装方便、顶进力较小等优点。
Abstract: Several kinds of the cross section forms of reinforced concrete arch culvert for urban comprehensive utility tunnel using jacking construction method are discussed. Based on the advantages of square and circular concrete arch culvert, a combination type concrete circular arch culvert is designed. The concrete circular arch culvert are produced by using core mould vibration technology and local reinforcement measures and have the advantages of excellent durability, high productivity, easy installation, and the small jacking force.
