Abstract

PURPOSE: To cut off shortcircuit lines and give rigidness against water pressure as the spacings of the end parts of branch collecting paths are covered even when the filtering vessel swells by continuously securing supporting crosspieces on the inside surface of the side wall of the vessel.
CONSTITUTION: Branch collecting paths 3 are crossed and arrayed over the main collecting path 2 buried in the bottom of a filtering vessel 1 and a filter layer 4 is provided over these collecting paths 3. Mortar is filled in the spacing 1B between the collecting paths 3 and the side wall 1A of the vessel 1. Supporting crosspieces 5 engaging with the collecting paths 3 in such a manner as to cover the end parts of the collecting paths 3 and mortar filling section 1B are continuously secured to the inside surface of the side wall 1A integrally with the side wall 1A. Even if with the above constitution the vessel 1 swells owing to water pressure and creates a spacing in the filling section 1B closing the end parts of the collecting paths 3, the layer 4 which purifies raw water and the crosspieces 5 cut off the shorting of this spacing and the layer 4 and give rigidness against water pressure to the side wall 1A.
