本工法是代替盾构施工法中的一次衬砌所用的砌块,在盾构尾部直接浇筑混凝土而作成衬砌的工法。日本jR樱本町駃构内下水道,内直径1500mm,长约288m一段使用盾构法施工,其中111m采用一般的混凝土砌块作一次衬砌,其余177m(含半径60m曲线段)试验用挤压混凝土作衬砌(见图1、2、3)。
This method is to replace the shield construction method used in the lining of a block, the direct placement of concrete at the tail of the shield lining method. Japanese jR Sakurahin-machi structure within the sewer, the inner diameter of 1500mm, length of about 288m using a shield construction, of which 111m with a common concrete block lining, and the remaining 177m (including the radius of 60m curve) test with extruded concrete Lining (see Figure 1,2,3).
