編前：千古百業興，先行在交通(tong)(tong)。一條條縱(zong)橫(heng)交錯的(de)(de)高(gao)(gao)速(su)(su)公路網(wang)，不僅暢通(tong)(tong)了(le)廣(guang)袤(mao)大地，更(geng)串聯起機遇和(he)希望。近(jin)期，備受關注的(de)(de)上(shang)林(lin)至(zhi)橫(heng)縣公路一期工(gong)程（簡稱上(shang)橫(heng)高(gao)(gao)速(su)(su)）即將揭開神秘面紗(sha)正式通(tong)(tong)車，這條連通(tong)(tong)上(shang)林(lin)、賓陽、橫(heng)州市的(de)(de)高(gao)(gao)速(su)(su)公路從開工(gong)到建(jian)成，凝聚了(le)全體參建(jian)人員的(de)(de)辛勤付(fu)出(chu)，也將為沿線村鎮(zhen)搭建(jian)起通(tong)(tong)往(wang)幸福生(sheng)活的(de)(de)振興之路。南(nan)寧交投集團官網(wang)、微(wei)信公眾號(hao)、視頻號(hao)同步推(tui)出(chu)《走進上(shang)橫(heng)高(gao)(gao)速(su)(su)》專欄(lan)，看(kan)上(shang)橫(heng)高(gao)(gao)速(su)(su)的(de)(de)建(jian)設風(feng)采、項目亮點(dian)，以及沿線風(feng)情(qing)，本(ben)期帶來樞(shu)(shu)紐(niu)互(hu)通(tong)篇——黎塘北(bei)樞(shu)(shu)紐(niu)互(hu)通(tong)。

黎塘北樞(shu)紐(niu)互(hu)通(tong)(tong)位于賓陽縣洋橋鎮茂(mao)凌村附近，聯(lian)通(tong)(tong)柳南(nan)高(gao)(gao)速公路(lu)，具有施工組織難度大、涉(she)路(lu)施工安全風(feng)險高(gao)(gao)、鋼箱梁頂推施工精度要(yao)求高(gao)(gao)等特點。

黎塘北樞紐互通采用現(xian)場組(zu)拼+多點(dian)步(bu)履(lv)式(shi)連(lian)續頂(ding)推(tui)施(shi)(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝，有效(xiao)縮短涉(she)路施(shi)(shi)工(gong)(gong)(gong)(gong)周期(qi)，減少施(shi)(shi)工(gong)(gong)(gong)(gong)期(qi)間對(dui)運營高速公路的通行(xing)能(neng)力及行(xing)車安(an)全的影響(xiang)。該跨(kua)路橋(qiao)梁是目前廣西(xi)境內第一座采用步(bu)履(lv)式(shi)頂(ding)推(tui)工(gong)(gong)(gong)(gong)藝跨(kua)越既有高速公路施(shi)(shi)工(gong)(gong)(gong)(gong)的曲(qu)線(xian)鋼箱(xiang)梁橋(qiao)。步(bu)履(lv)式(shi)頂(ding)推(tui)施(shi)(shi)工(gong)(gong)(gong)(gong)技術相較于拖拉(la)式(shi)、推(tui)移式(shi)頂(ding)推(tui)工(gong)(gong)(gong)(gong)藝上(shang)，能(neng)有效(xiao)解決拖拉(la)式(shi)頂(ding)推(tui)“蛙跳”通病現(xian)象，能(neng)減少長距(ju)離滑道的設置，能(neng)安(an)裝更大跨(kua)度、重量更重的鋼箱(xiang)梁，在頂(ding)推(tui)過(guo)程中也顯得更加(jia)平穩、高效(xiao)。
