專業c型聚能管水壓光面爆破技術在隧道掘進作業中的實際應用。提升光面爆破水平、嚴抓隧道超挖管控進行了介紹。聚能水壓光面爆破工藝技術很成熟、可操作性很強、材料成本很低、施工速度很快、節能環保效果很顯著、經濟效益社會效益很高。一是要提高對推廣該項技術重要性和必然性的認識;二是要樹立必須采取聚能水壓光面爆破的意識;三是要堅持培訓、示范、監督“三位一體”;四是要制定切實的獎懲制度;五是要建立檢查監督機制，持續促進該項技術的深入推廣。c型聚能管價格在隧道施(shi)工的現(xian)場管理、科技(ji)創新、人才培(pei)養、經濟(ji)效益等(deng)方面的不足。建議(yi)對(dui)施(shi)工一(yi)線基礎技(ji)術工作(zuo)扎(zha)實推進(jin);對(dui)新工藝、先進(jin)工法要深(shen)入學習鉆研;對(dui)消極懈怠、故步(bu)自封的思想(xiang)要堅決抵(di)制。
