芭乐app官网:管廊

管(guan)廊(lang)，即管(guan)道的(de)(de)走廊(lang)。化工(gong)及其相关类工(gong)厂中(zhong)(zhong)很多(duo)管(guan)道被集(ji)中(zhong)(zhong)在一起，沿着装置或(huo)厂房外布置，一般(ban)是在空中(zhong)(zhong)，用(yong)支架撑起，形成和走廊(lang)类似的(de)(de)样子。也有少(shao)数管(guan)廊(lang)位(wei)于(yu)地下。

一般都呈“开”型.

大型装置管道集中敷设的主(zhu)要场(chang)所，它由(you)钢结(jie)构(gou)或钢筋混凝土结(jie)构(gou)的立柱(zhu)、横梁以及(ji)桁架所构(gou)成，按类型可(ke)分为单层(ceng)或多层(ceng)，可(ke)通(tong)(tong)行的或不可(ke)通(tong)(tong)行的等。

安全厂用(yong)(yong)(yong)(yong)水(shui)(shui)供(gong)水(shui)(shui)管(guan)(guan)廊(lang)（GA）  GA管(guan)(guan)廊(lang)是(shi)重要(yao)厂用(yong)(yong)(yong)(yong)水(shui)(shui)（SEC，重要(yao)厂用(yong)(yong)(yong)(yong)水(shui)(shui)系(xi)统(tong)）供(gong)水(shui)(shui)管(guan)(guan)廊(lang)，连接联(lian)合泵房（PX）和电(dian)(dian)气(qi)(qi)厂房（LX）。SEC系(xi)统(tong)是(shi)为核岛(dao)设(she)备冷却水(shui)(shui)系(xi)统(tong)（RRI）提(ti)供(gong)冷却水(shui)(shui)的(de)(de)直流系(xi)统(tong)，并且通过GA管(guan)(guan)廊(lang)向常规岛(dao)和核岛(dao)提(ti)供(gong)消防水(shui)(shui)。另一(yi)个(ge)(ge)(ge)作(zuo)用(yong)(yong)(yong)(yong)是(shi)将电(dian)(dian)气(qi)(qi)厂房(LX)的(de)(de)应急电(dian)(dian)源分四个(ge)(ge)(ge)系(xi)列送至联(lian)合泵房(PX)，在(zai)(zai)GA沟(gou)中，一(yi)侧(ce)布(bu)(bu)置工艺管(guan)(guan)道，另一(yi)侧(ce)布(bu)(bu)置电(dian)(dian)缆(lan)桥架，中间(jian)至少有(you)0.8m的(de)(de)人(ren)行(xing)通道，以保(bao)证桥架安装、电(dian)(dian)缆(lan)敷设(she)和在(zai)(zai)役检查时人(ren)员和器(qi)具的(de)(de)顺利通过。除这些外(wai)，GA管(guan)(guan)廊(lang)内还(hai)布(bu)(bu)置有(you)仪控(kong)设(she)备，每两台(tai)机(ji)组四条GA管(guan)(guan)廊(lang)内共设(she)置四个(ge)(ge)(ge)集水(shui)(shui)坑，每个(ge)(ge)(ge)集水(shui)(shui)坑内设(she)一(yi)个(ge)(ge)(ge)浮球液位控(kong)制器(qi)，高(gao)液位报警信号送至KIC系(xi)统(tong)。  GA管(guan)(guan)廊(lang)属于抗(kang)震(zhen)(zhen)I类构筑(zhu)物，采用(yong)(yong)(yong)(yong)地震(zhen)(zhen)震(zhen)(zhen)动（SL-2）进行(xing)抗(kang)震(zhen)(zhen)设(she)计。GA廊(lang)道通常采用(yong)(yong)(yong)(yong)地下(xia)现(xian)浇(jiao)钢(gang)(gang)筋混凝(ning)土(tu)结构，举(ju)例来说，红沿河GA廊(lang)道断面(mian)尺寸：高(gao)×宽＝2.7m×2.8m，顶板(ban)(ban)、底(di)板(ban)(ban)和侧(ce)壁的(de)(de)厚度均为0.6m。伸缩缝(feng)宽50mm，伸缩缝(feng)间(jian)距约20m。底(di)板(ban)(ban)内底(di)标(biao)高(gao)为-6.5m～-8.85m。混凝(ning)土(tu)强度等级(ji)为C40，抗(kang)渗等级(ji)W10。钢(gang)(gang)筋采用(yong)(yong)(yong)(yong)HRB400级(ji)和HRB335级(ji)。
