The invention also provides a segmented construction method for the FRP tube-concrete-steel tube combined tube tower. When the combined tube tower or similar tower-shaped or columnar structure is implemented, long tubes and large prefabricated concrete parts do not need to be transported The combined tube tower has high construction speed, the steel tube adapting piece and the FRP tube adapting piece can also serve as shear keys between the concrete layer and two tubes and the stiffening ribs of two tubes, thus improving the structural property of the combined tube tower.; 本发明涉及一种FRP管-混凝土-钢管组合管塔，包括由多个钢管节段连接构成的钢内管、由多个FRP管节段连接构成的FRP外管以及浇筑在两者之间的混凝土层；钢内管的相邻钢管节段之间通过钢管连接件进行连接，钢管连接件位于钢内管的外表面；FRP外管的相邻FRP管节段之间通过FRP连接件进行连接，FRP连接件位于FRP外管的内表面；且钢管连接件和FRP连接件均内嵌于所述混凝土层中。本发明还提供了该FRP管-混凝土-钢管组合管塔的分节段建造方法。实施本发明及类似的塔状或柱状结构无需运输长管和大型预制混凝土部件，建造速度快，且钢管连接件和FRP管连接件还可作为混凝土层和两管之间的剪力键以及两管的加劲肋，提高了组合管塔的结构性能。 http://hdl.handle.net/10397/4712 Title: Concrete paving brick capable of purifying air and method for manufacturing the same = 可净化空气的混凝土铺路砖及其制造方法<br/><br/>Authors: Poon, C.
