徐工EBZ230懸臂式掘進機在2014年助力湖南省龍永高速公路，這是湖南省內首臺先進的懸臂式掘進機設備，以現(xiàn)代科技手段為隧道施工插上安全、質量的“雙翼”，推動了隧道工程安全、質量建設。徐工EBZ230懸臂式掘進機采用懸臂式截割頭對圍巖迅速進行切割，掘進量為80立方米/小時，具有作業(yè)快、粉塵少、安全系數(shù)高等特點，且掘進機的雙搖桿隨動機構還能實現(xiàn)運輸機前溜槽和鏟板后溜槽的平滑連接，可直接將切割后的物料通過鏈輪輸送至渣土車上，開挖進度有效提高，施工效率將在傳統(tǒng)隧道施工技術的基礎上提高4-5倍。由于地質條件十分復雜，該隧道采用傳統(tǒng)的施工方法進行爆破對巖層擾動較大，易引發(fā)塌方等系列安全問題。采用徐工EBZ230懸臂式掘進機后，可以直接利用掘進機的切割頭對圍巖迅速進行切割，有效杜絕了由爆破引發(fā)的安全問題。青海專業(yè)隧道掘進機銷售徐工集團EBZ160型掘進機應用研究。</p><div
