确定外管廊柱子位置时应考虑哪些因素?确定外管廊高度时应考虑哪些因素?
Reply #22020-07-07
本帖最后由 a328958874 于 2020-7-7 09:41 编辑 1、①装置内管廊应处于易与各类主要设备联系的位置上,要考虑能使多数管线布置合理、少绕行,以减少管线长度。典型的位置是在两排设备的中间或一排设备的旁侧。②布置管廊时要综合考虑道路、消防的需要,以及电线杆、地下管道和电缆布置和临近建、构筑物等情况,并避开大、中型设备的检修场地。③管廊上部可以布置空冷器、仪表和电气电缆槽等,下部可以布置泵等设备。④管廊上设有阀门,需要操作或检修时,应设置人行走道或局部的操作平台和梯子。2、管廊底层净高主要考虑下列因素: ①管廊下面布置的设备所需要的净高。 ②管廊下面有检修通道时,要考虑有汽车或吊车通过的要求,一般通道最小净高及底层梁至地面最小净空见HG/T20546—2009。 3、管廊两层之间的距离。应根据管道直径的大小及管架结构尺寸、检修要求等具体情况而定,但最小净距为1.5m。管道较多时,常用的两层之间的距离为2m。 4、两管廊“T”形相交时应取不同的标高,其高差可根据管道直径确定;一般以750~1000mm为宜。 5、管架柱间距,一般为4~9m,最常见为6m,因有些管道必须采用柱子支承。
