PURPOSE: A deformation resisting valve chamber is provided to ensure lightweight design by engaging ribs to generate bearing stress for obtaining excellent stress with respect to soil pressure and an upper load. CONSTITUTION: A deformation resisting valve chamber comprises an arch type ceiling part, a vertical type wall, a bottom part, and a lattice inner rib. The inner rib comprises an arch type lateral rib, a linear longitudinal rib, and a linear vertical rib. The inner rib is protruded into a valve chamber from the arch type ceiling part and vertical type wall. The inner rib is formed with a plurality of holes for connecting wires and is tension-adjustably connected with the wires. |
