梧(wu)柳(liu)7標六(liu)(liu)(liu)巷互(hu)(hu)通(tong)(tong)(tong)是在(zai)原有梧(wu)州至(zhi)柳(liu)州高(gao)速(su)公路上(shang)增設的(de)(de)(de)項目(mu),位于主線(xian)K130+130—K131+080處(chu),采用A形單喇(la)叭互(hu)(hu)通(tong)(tong)(tong)式立交設計(ji),設計(ji)時速(su)40Km/h,匝道最(zui)小平曲線(xian)半徑50m。六(liu)(liu)(liu)巷互(hu)(hu)通(tong)(tong)(tong)采用整(zheng)體(ti)(ti)(ti)式現(xian)澆箱梁施(shi)工(gong)的(de)(de)(de)橋(qiao)梁共計(ji)4座(zuo),整(zheng)體(ti)(ti)(ti)式現(xian)澆高(gao)度(du)最(zui)高(gao)達34m,地(di)處(chu)低山丘陵(ling)區(qu),地(di)形條件復雜,材料(liao)運(yun)輸困難(nan)等種(zhong)種(zhong)不利條件造成了(le)六(liu)(liu)(liu)巷互(hu)(hu)通(tong)(tong)(tong)現(xian)澆箱梁施(shi)工(gong)難(nan)度(du)高(gao)、技術要求高(gao)、施(shi)工(gong)作業繁瑣的(de)(de)(de)特(te)點。
梧柳(liu)7標采用(yong)新工藝、新技術(shu)攻(gong)克(ke)了(le)整體式現澆(jiao)高度大且地形復(fu)雜(za)條(tiao)件下(xia)高難度的(de)(de)整體式現澆(jiao)施(shi)工,裝配式螺旋(xuan)(xuan)管(guan)支架是整體式現澆(jiao)施(shi)工中的(de)(de)亮(liang)點(dian),裝配式高大螺旋(xuan)(xuan)管(guan)支架的(de)(de)應用(yong),有力推進了(le)六巷互通施(shi)工生產(chan),項(xiang)目技術(shu)人員還以裝配式高大螺旋(xuan)(xuan)管(guan)支架為科研活(huo)動的(de)(de)基礎,成功發布(bu)了(le)2項(xiang)QC成果和1項(xiang)施(shi)工工法。
