新管幕工法虽然是管幕工法的一?#25351;?#36827;,但是与管幕工法有很大的区别。有别于传统暗挖法先挖地下土方再搭主体结构,新管幕工法则是先用钢管搭起支护结构,再挖土方。下面就由八方陆通的冻结管打设工程技术人员为您讲解。
  
  1、新管幕工法应用范围广泛,可应用于穿越城市公路、铁路的地下车道或人?#26800;?#30340;施工,还可用于地下大断面结构物的施工,比如地铁站地下车库等的施工。适用于回填土、砂土、黏土、岩层等各种地层,必要时工程不需降水,在施工中采取止水措施处理。
  
  2、新管幕工法所顶钢管均为大?#26412;?#38050;管(?#26412;?#19968;般在1800mm以上)。采?#20040;籩本?#38050;管的目的,就是可以在施工后期直接将拟建结构物外轮廓施做于所定钢管形成的管排内,从而完成地?#38470;?#26500;的构筑。
  
  3、新管幕工法是全新的暗挖工法,其核心思想有异于传统管幕工法,它是利?#20040;籩本?#30340;顶管施工,形成全部或部分永久?#32440;?#28151;凝土结构,在此永久?#32440;?#28151;凝土结构的支护下,进行暗挖结构土方大开挖,最终完成全部地?#38470;?#26500;。
