<p>PURPOSE:To bury an osmotic tube smoothly and accurately by inserting a plug body into an osmotic hole, and by mounting on and fixing to a tube wall through a bolt freely attachable and detachable. CONSTITUTION:Multiple osmotic holes 2 are formed in parallel on a tube wall of an osmotic tube 1, and a plug body 3 of the outer diameter almost the same with the inner diameter of the osmotic hole 2 is inserted into the osmotic hole 2. A protrusion 6 is mounted on an anchor bolt 7 that is preliminarily embedded in the wall surface of the osmotic hole 2 through a bolt 8, and the plug body 3 is made freely attachable and detachable, while a mortar layer 9 is formed on the outer surface of the plug body 3. After the osmotic tube 1 is buried, the bolt 8 is removed, while the plug body 3 is removed to the inside of the osmotic tube 1, and the mortar layer 9 is broken and removed. An osmotic filter frame 10 is further inserted into the osmotic hole 2, and is mounted and fixed by the bolt 8 as well as the anchor bolt 7. An osmotic filter 11 is installed in the filter frame 10.</p> |
