17、.............................................................................223.1架梁架梁總體方案體方案在榆次西站存梁，在南同蒲上行線DK375400處引入施工便線。修建施工便線2條，并分別在DK375701.95和DK376001處鋪設(shè)便線9號道岔2組，并重鋪其中1組，站內(nèi)機(jī)車分3次將40片梁全部推入施工便線，便線內(nèi)架梁租用機(jī)車牽引運(yùn)梁車移位。沿新建線路

18、上行線靠既有上行線側(cè)順橋向修建運(yùn)梁便道至侯馬方橋臺(tái)，采用四臺(tái)輪胎式運(yùn)梁車運(yùn)梁，一臺(tái)200T和一臺(tái)160T輪胎式吊車吊架梁。橋上鋪設(shè)25m標(biāo)準(zhǔn)軌和短軌排過渡，軌排采用橋下組裝，吊車吊裝上橋，架梁后整道達(dá)標(biāo)后換鋪長鋼軌。施工順序：便線布置如圖一所示。運(yùn)梁采用2輛DL1專用預(yù)制梁車中間加掛1輛游車，每片梁所用車輛長度按42m計(jì)，便線1線路內(nèi)最多存放6片梁車。第一次，要點(diǎn)拉入12片梁，存放于便線2道，經(jīng)計(jì)算便線長度滿足存梁及架梁運(yùn)轉(zhuǎn)需要。機(jī)車將

19、第一片梁移至2#岔前，吊車將梁吊至汽車運(yùn)梁車后，2#道岔扳道開通便線1道，機(jī)車推送鐵路運(yùn)梁平車空車經(jīng)2#道岔退入便線1道，機(jī)車返回至橋頭，道岔扳回，機(jī)車牽引便線2道上的運(yùn)梁車前行至吊車位卸第2片梁。配備汽車運(yùn)梁車4臺(tái)，吊車將4片梁全部吊放至運(yùn)梁汽車上后，移位至橋梁架設(shè)孔位，運(yùn)梁炮車運(yùn)梁到位，一次架設(shè)雙線，并焊接橫向聯(lián)結(jié)板，鋪設(shè)梁上線路。架設(shè)一孔后，吊車行至卸梁位按上述程序卸梁架梁。本次梁片架設(shè)大橋第1、2、3孔。當(dāng)?shù)谝淮蔚?2片梁架設(shè)完
