These <br />Should be no Larger Than <br />Necessary to Clear the Bell. <br />NOTES: <br />1. These trench and bedding details are for pipe structural requirements only. The <br />contractor is solely responsible for safety of operations. The contractor shall slope <br />trench walls, provide protective work boxes, and/or shore and brace all <br />excavations as the contractor determines necessary for safety of operations, and <br />in conformance to IOSHA Regulation 29 C.F.R. 1926, Subpart P for Trench Safety <br />Systems. <br />2. All PVC pipe for sanitary sewers shall be installed in accordance with ASTM D2321. <br />J. There shall be no rocks or stones greater than 2" in any dimension within 6" of <br />the pipe wall or bell. <br />4. Flexible Pipe: Embedment materials for bedding, haunching and initial backfill shall <br />comply with the requirements of ASTM D2321, Classes I (INDOT #8 or #9), II <br />(INDOT #53, #73, or B-Borrow), or III and shall be compacted as noted. Refer to <br />pipe manufacturers recommended bedding and embedment material class type <br />requirements. Removable flowable backfill shall be placed for all areas within 5 feet <br />of pavements to 12" above pipe crown. Above this limit structure backfill shall be <br />used. <br />5. Rigid Pipe: Embedment materials for bedding, haunching and initial backfill shall <br />comply with the requirements of ASTM C12 (VCP) Classes A, B, C or crushed <br />stone (INDOT #8, #9 or B-Borrow) and shall be compacted as noted. Removable <br />flowable backfill shall be placed for all areas within 5 feet of pavements to 12" <br />above pipe crown. Above this limit structure backfill shall be used. <br />6. Final backfill shall not contain debris, organic material, frozen material, unstable <br />material or boulders or stones greater than 2" in any dimension. Flowable fill <br />optional. <br />7. The placement and compaction of backfill shall not cause displacement of the <br />pipe. <br />8. For multiple pipes in some trench: <br />a. Place bedding to Spring Line of first pipe across entire trench width. <br />b. Placement of next pipe, re -excavate trench as needed. Then place bedding <br />as noted above. <br />c. For additional pipes repeat as required. <br />9.
