Abstract
PURPOSE: To detain mortar even if the filled mortar peels from the side wall of the filtering vessel, suppress the production of shortcircuit lines and fix branch collecting paths in the disposed positions by securing core metals in the mortar filling section at the end part of the branch collecting paths of the filtering vessel.
CONSTITUTION: A main collecting path 2 is buried in the bottom of a filtering vessel 1. Branch collecting paths 3 are crossed and arrayed over this and further a filtering layer 4 is provided over these collecting paths 3. Mortar is filled in the spacing 1B between the arrayed collecting paths 3 and the vessel side wall 1A and core metals 5 to be interposed in the filled mortar are secured to the vessel side wall 1A in the mortar filling section 1B. With the above constitution, raw water is filtered in the layer 4 and the clean water is guided from the collecting paths 3 into the collecting path 2 and at the same time the backwashing water is distributed to each part of the layer 4. In this case, the filling section 1B prevents the leakage of the backwashing water and even if the mortar in the filling section 1B peels owing to the impact of the dynamic pressure of the backwashing water, it is prevented from dislodging and moving by the core metals 5 detained to the side wall 1A, thereby closing the end parts of the collecting paths 3.
