To easily assemble an inside form even during the pressurizing and curing process of a lining concrete.
In this ECL method (cast-in-place concrete shielding method), a lining concrete 3 is placed in the space between a tunnel ground wall 1 excavated by a shielding machine and an inside form 2 assembled in the inside of the ground wall 1 and the lining concrete 3 is pressurized and cured to construct a dense concrete lining tunnel closely stuck to the ground wall. This device is provided with a press jack 6 installed in the inside of the skinplate 4 of the shielding machine and stretched to the axial direction of the tunnel and a press 8 installed between the skin plate 4 and the inside form 2 to move in the axial direction of the tunnel in accordance with the drive of the press jack 6 and pressurize the lining concrete 3.
