5月27日晚(wan),都(dou)巴一(yi)分部紅(hong)河村(cun)高架(jia)大(da)橋(qiao)首根(gen)樁基砼澆筑順利完成。
紅(hong)河村高架大橋位于河池(chi)市都安縣紅(hong)河村附近,為主線道路新建橋梁,設計橋型右線為9×20m,左線為10×20m,橋寬11.75m,預應力砼小箱梁。右線橋梁中心樁Y1K362+026,起點樁號Y1K361+931,終點樁號Y1K362+121,橋長190m,橋面設計高程約162.761~160.768m;左線橋梁中心樁號Z1K362+036,起點樁號Z1K361+931,終點樁號Z1K362+141,橋長210m,橋面設計高程約162.582~161.810m。
此次(ci)紅(hong)河村高架橋5-0樁(zhuang)基砼(tong)澆筑,從(cong)準(zhun)備工(gong)(gong)作到樁(zhuang)基砼(tong)澆筑完成,每一步工(gong)(gong)序(xu)分(fen)部(bu)都嚴格(ge)把關。從(cong)測量放樣,埋設(she)鋼護筒;到鉆(zhan)機鉆(zhan)孔、清孔,試(shi)驗室檢測三大指(zhi)標;再到安放鋼筋籠(long)、導管、二次(ci)清孔;最后灌注混凝土,分(fen)部(bu)秉承“安全(quan)(quan)第(di)一預防為主”的安全(quan)(quan)生產方(fang)針,從(cong)技(ji)術交底、施(shi)工(gong)(gong)方(fang)案、人(ren)員設(she)備、材料供(gong)應等角度進(jin)行周密部(bu)署,對全(quan)(quan)體職(zhi)工(gong)(gong)進(jin)行崗前安全(quan)(quan)教(jiao)育(yu)培訓,確保了(le)橋梁樁(zhuang)基鉆(zhan)孔樁(zhuang)施(shi)工(gong)(gong)安全(quan)(quan)、標準(zhun)、有序(xu)開展。
