在我国,对带钢筒的混凝土管(下称带钢筒管)还较陌生,所以本文先简要介绍一下国外的一些情况,再结合我国的现状谈谈它在我国的发展前景。一、国外带钢筒管的发展概况带钢筒管分带钢筒的钢筋混凝土管和带钢筒的预应力混凝土管两种,与钢管的区别在于它的抗渗性由薄钢筒保证;强度由钢筋或预应力钢筋承受;而刚度则由钢筒、钢筋和内、外层混凝土共同承担。第1根带钢筒管是由法国的邦纳工程师于1893年在巴黎制造的。第2年用这些管在巴黎安装了一条口径1800毫米、长1.5公
In China, the concrete pipe with steel tube (hereinafter referred to as the steel tube) is still relatively unfamiliar, so this article first briefly introduces some foreign situations, and then talks about its development prospects in China combined with the status quo in China. First, the development of the status of the foreign strip steel tube Steel strip tube reinforced concrete pipe with steel tube and prestressed concrete pipe with steel tube two, and the difference is that its impermeability by thin steel tube guarantee; The strength is borne by steel bars or prestressed steel bars; and the rigidity is shared by steel cylinders, steel bars and inner and outer concrete. The first strip tube was manufactured in Paris in 1893 by a Bonner engineer in France. In the second year, these tubes were installed in Paris with a diameter of 1800 mm and a length of 1.5 km.
