Method, system and device for building a wall in the ground |
摘要 |
A wall is built in the ground by pulling a wall building device having cross-sectional dimensions which are substantially equal to the dimensions of at least a part of the cross-section of the wall through the ground, at least a part of the wall being formed by injecting a hardenable material behind the wall building device. A tunnel is made by first making a tunnel wall, leaving the ground inside the tunnel wall substantially intact, followed by excavating the ground inside the tunnel wall.
