摘要 | PURPOSE: To make a fastening bolt unnecessary by supporting a pipe which protects a pipeline in a road bridge and the like by forming in sheath pipe structure with a support made of ultrahigh molecular weight polyethylene, and fixing the support to the outside of a sheath pipe-inside piping with epoxy resin base mortar. CONSTITUTION: When a pipeline is installed in a road bridge and the like, in order to prevent leakage diffusion, the pipeline (piping 1) is installed as a sheath pipe-inside piping to protect the piping 1. For supporting the piping 1 on the inside of a sheath pipe 5 with a support 2, the support 2 is formed as an insulating sliding support with ultrahigh molecular weight polyethylene, and fixed to the outside of the piping 1 with epoxy resin base mortar 3. When the sliding support 2 is fixed to the piping 1, the support 2 is built in the piping 1 together with a circular steel mold frame 4 set to the support 2, and the mortar 3 is filled from a filling hole 2a formed in the support 2. After solidifying the mortar 3, the mold frame 4 is removed to finish installation. COPYRIGHT: (C)1995,JPO |
