综合管廊重型装配式管线支架设计要点

Design Points for Heavy Built-up Support in Urban Utility Tunnel

近年,国内综合管廊市场处于大发展时期,已开工建设城市综合管廊4000km以上。综合管廊内使用数量最多的管线支架担负着管线安全、稳定运营的作用。一方面,综合管廊内管线支架数量可观,关系着管线入廊的建设成本;另一方面,支架稳固对管线安全起着至关重要的作用。因此,重视重型装配式管线支架的设计要点具有重要意义。

In recent years,urban utility tunnel is entering a period of important development in China.And it has been built for more than4000km.Built-up supports can keep pipeline safe and steady which are widely and numerous applied.On the one hand,construction cost is related with built-up supports quantity.On the other hand,built-up supports also play an important role in pipeline safety.Therefore,it has important significance to pay great attention to design points for heavy built-up suppor t.
