TUNNELING COMPLEX AND SLIME VESSEL Russian patent published in 1994 - IPC

FIELD: construction of tunnels in inundated grounds. SUBSTANCE: press-out chamber is communicated by means of pipeline for discharge of liquid phase of slime with loading opening of slime vessel. Discharge hollow of slime vessel is communicated by supply pipeline through system of passages made in press-out chamber with perforation of press-out chamber. Loading opening of slime vessel is arranged for communication, either, with discharge hollow, or with unloading opening by means of turning gate made in form of rocker. One arm of rocker has perforation, and the other arm is installed above unloading opening. Feed pump is installed in body of slime vessel above additional pump and connected with discharge hollow by means of filter. Such a realization of tunneling complex and slime vessel makes it possible to clean perforations of press-out chamber and slime vessel in process of transportation of liquid phase without use of additional source of water. EFFECT: higher efficiency. 10 cl, 2 dwg
