    • A construction method of a girder bridge with a later-tension precast floor slab is provided to manage the girder bridge effectively by introducing compression stress to the precast floor slab and controlling the tensile crack generation. A concrete(C) is poured on an abdomen of a negative moment part girder. A positive moment part girder and the negative moment part girder are continuously placed on a pier(500). A precast floor slab(300) laid with sheath pipes is mounted on the negative moment part girder. Non-attached steel wires(330) are inserted in the sheath pipe and then tensed to apply compression force to the precast floor slab. The concrete is poured and hardened between the upper and abdomen parts of the positive moment part girder and on the connected parts between the positive and negative moment part girders.

    • Provided in the present invention is a pipe connection structure by a metal casting, including more than two pipes requiring a connection; a cover member surrounding the pipes to have a space portion between the pipes; a joint portion for joining the cover member with the pipes; and a casting injected into the space portion through an injection hole formed on the cover member. After being injected through the injection hole, the casting is hardened to join the pipes on both sides. According to the present invention, even when a sealing of the pipe joint portion is damaged due to a fatigue failure, a local heating can be performed to re-melt the casting inside the pipes to harden and re-guarantee the sealing.
