Abstract
'Cast-in-place concrete lining method' is one of the Shield tunnel construction method. By this method, the shield machine is drived by the reaction due to pressing the cast-in-place fresh concrete at high pressure. This method has many advantages, the settlement of ground is extremely little, the process of work is shortened, the lining is constructed economically and high quality, and etc. This paper describes the introduction of 'Cast-in-place concrete lining method', the character of pressed concrete and the abstract of experimental construction.
