<p>PURPOSE:To position a pipe body to be buried for sewage treatment prior to the burying construction, secure a positioned condition unmovable and eliminate deflecting motion of the pipe body at the time of charging earth and sand. CONSTITUTION:A position regulation device 1 is wedge-shaped comprising a bottom surface 2 to be placed on a support body 11 to support a pipe body 12 to be buried, and an arc surface 3 to get in contact with a lower outer circumference of-the pipe body 12. A number of crest-grooves 4, 5 extended in the axial direction of the pipe body 12 are formed at least in part of the bottom surface 2 and the arc surface 3. Next, in the condition where the regulation device 1 is inserted in delta gaps between time support body 11 and the pipe body 12 to position the pipe body 12, retraction of the regulation device 1 is prohibited by the grooves 4 in the bottom surface 2. In addition, rotation of the pipe body 12 is prevented by the grooves 5 in the arc surface 3, thereby deflection of the position of the pipe body 12 at the earth and sand charging time can be securely prevented.</p> |
