管(guan)廊(lang)(lang)，即(ji)管(guan)道(dao)的(de)走(zou)廊(lang)(lang)。化工及其(qi)相关类(lei)工厂中(zhong)很多管(guan)道(dao)被集中(zhong)在一(yi)起，沿着装置或厂房外布置，一(yi)般是(shi)在空中(zhong)，用(yong)支架撑起，形成和(he)走(zou)廊(lang)(lang)类(lei)似的(de)样子(zi)。也有(you)少数(shu)管(guan)廊(lang)(lang)位于地下。

一般都呈“开”型.

大型装(zhuang)置管道集中敷设(she)的主要场所(suo)，它由钢结(jie)构或(huo)钢筋混凝土结(jie)构的立柱、横梁以及桁(heng)架所(suo)构成，按类型可分(fen)为单层(ceng)或(huo)多层(ceng)，可通行(xing)的或(huo)不可通行(xing)的等。

安全厂用(yong)(yong)(yong)(yong)(yong)水(shui)供(gong)(gong)水(shui)管(guan)(guan)(guan)(guan)(guan)廊(lang)(lang)（GA）  GA管(guan)(guan)(guan)(guan)(guan)廊(lang)(lang)是重要厂用(yong)(yong)(yong)(yong)(yong)水(shui)（SEC，重要厂用(yong)(yong)(yong)(yong)(yong)水(shui)系(xi)(xi)(xi)统(tong)）供(gong)(gong)水(shui)管(guan)(guan)(guan)(guan)(guan)廊(lang)(lang)，连(lian)接联合泵房(fang)（PX）和电(dian)气厂房(fang)（LX）。SEC系(xi)(xi)(xi)统(tong)是为(wei)核岛(dao)设(she)备冷却水(shui)系(xi)(xi)(xi)统(tong)（RRI）提供(gong)(gong)冷却水(shui)的(de)直(zhi)流(liu)系(xi)(xi)(xi)统(tong)，并(bing)且通过GA管(guan)(guan)(guan)(guan)(guan)廊(lang)(lang)向常规(gui)岛(dao)和核岛(dao)提供(gong)(gong)消防水(shui)。另一(yi)个作(zuo)用(yong)(yong)(yong)(yong)(yong)是将电(dian)气厂房(fang)(LX)的(de)应急(ji)电(dian)源分四(si)个系(xi)(xi)(xi)列(lie)送至(zhi)(zhi)(zhi)联合泵房(fang)(PX)，在GA沟(gou)中(zhong)，一(yi)侧布置(zhi)工艺管(guan)(guan)(guan)(guan)(guan)道(dao)，另一(yi)侧布置(zhi)电(dian)缆桥架(jia)，中(zhong)间(jian)至(zhi)(zhi)(zhi)少(shao)有0.8m的(de)人行通道(dao)，以(yi)保证桥架(jia)安装、电(dian)缆敷设(she)和在役检查时人员和器具的(de)顺利通过。除这些外，GA管(guan)(guan)(guan)(guan)(guan)廊(lang)(lang)内(nei)还(hai)布置(zhi)有仪控(kong)设(she)备，每两台机组四(si)条GA管(guan)(guan)(guan)(guan)(guan)廊(lang)(lang)内(nei)共设(she)置(zhi)四(si)个集水(shui)坑，每个集水(shui)坑内(nei)设(she)一(yi)个浮球液位控(kong)制器，高(gao)液位报警(jing)信号送至(zhi)(zhi)(zhi)KIC系(xi)(xi)(xi)统(tong)。  GA管(guan)(guan)(guan)(guan)(guan)廊(lang)(lang)属于抗(kang)震(zhen)I类构筑物，采用(yong)(yong)(yong)(yong)(yong)地(di)震(zhen)震(zhen)动(dong)（SL-2）进行抗(kang)震(zhen)设(she)计。GA廊(lang)(lang)道(dao)通常采用(yong)(yong)(yong)(yong)(yong)地(di)下现浇钢(gang)筋(jin)混凝土结构，举例(li)来说，红沿河GA廊(lang)(lang)道(dao)断面尺寸：高(gao)×宽＝2.7m×2.8m，顶板、底板和侧壁的(de)厚度(du)均为(wei)0.6m。伸缩(suo)缝宽50mm，伸缩(suo)缝间(jian)距约20m。底板内(nei)底标高(gao)为(wei)-6.5m～-8.85m。混凝土强度(du)等级(ji)为(wei)C40，抗(kang)渗等级(ji)W10。钢(gang)筋(jin)采用(yong)(yong)(yong)(yong)(yong)HRB400级(ji)和HRB335级(ji)。
