Abstract (en)
[origin: ES8304258A1] A method and apparatus for forming continuous concrete walls in tunnels or galleries is provided. More particularly, the invention relates to a form that is slidable through the gallery or tunnel. The form is an elongated supported tubular structure generally conforming to the shape of the gallery or tunnel. The outermost surface of the form is spaced from the wall of the gallery or tunnel a sufficient distance to enable an appropriate amount of concrete to be poured or pressed therein. The form is adapted to have the concrete pumped into the annular spaced provided for it, and to have the force of the concrete against the leading edge of the form cause the form to slidably advance through the gallery or tunnel.
