                桥梁支撑立柱选用环亚ag88国际厅娱乐和螺旋钢管哪种好

                时间:2018-11-15 浏览:

                    桥梁支撑立柱一般选用环亚ag88国际厅娱乐,因为环亚ag88国际厅娱乐比无缝钢管性能要差一点,比螺旋钢管性能要强一点,价格也是同样比无缝便宜,比螺旋贵,使用环亚ag88国际厅娱乐既能保证工程的安全又能节省∮成本,这也是被广泛使用的原因。

                桥梁支撑立柱

                   每个工程在施工前都会提前选用工程使用的钢管材质,用于桥梁工程支撑通常选用的材质有以下几种,Q345B、Q345E、Q345D、Q345qD,这四种材质的综合性能基本相符,都是低碳合金材质,耐腐蚀,抗拉,硬度高,韧性强,主要用于桥梁打桩使用≡,材质的使用也是根据地形和工程来选的,普通平原地使用的▲是锰板Q345B材质,高气流沿海地区使用Q345E材质,高架桥工程使用Q345qD材质,高铁桥梁使用Q345D材质。
