袋装混凝土衬砌施工法是在地层与模板之间的环状空间里,将混凝土装入尼龙布袋中加压脱水,形成隧道衬砌的施工方法,其混凝土具有高密实性、高强度及高耐久性等优点,适合于有地下水、易坍塌地层中的施工。施工过程中需要对混凝土施加压力,这有利于地层的稳定。原文介绍了袋装混凝土的工艺、材料试验及力学试验情况,举出工程实例,某双车道公路隧道侧壁导坑穿越岩锥堆积地层,易坍方落石,施
Bagged concrete lining construction method is in the annular space between the formation and the template, the concrete filled nylon bag pressurized dehydration, the formation of tunnel lining construction method, the concrete with high density, high strength and high durability And other advantages, suitable for groundwater, collapsed formations in the construction. The construction process needs to exert pressure on the concrete, which is conducive to the stability of the formation. The article introduces the bagged concrete technology, material testing and mechanical testing conditions, cited examples of engineering, a two-lane road tunnel side pits through the rock cone accumulation of stratum, easy collapse side rock, Shi
