Abstract

An erection method by simple tower instrument during upper bridge construction installation, consists of installing 8 bolt1 ½″-400 and lower joint plate 24 mm bold, 50 cm on head of bridge construction pillar as hook designed tower, installing 5 locking plates from lower plate with 24 mm bold, 42 cm height as joint of premier steel pile30 cm, 6.5 mm bold, through 8 bolts and lower joint plate on every head of bridge construction pillar, installing and locking wind fastener15 cm through joint plate 16 mm bold and 4 bolts ¾″ to unite premier tower 330 cm, 6.5 mm bold, locating axis bearings 6 cm on outer side of premier tower as supporting part to tie and tension cable to tower, locating front stays with to 70 degree to tower to put premier supporter on premier tower through bearings, locating back stays with 50 degree to tower to stabilize tower on rear tower pillar through bolt on bridge pillar, locating arc construction onto pontoon using crane, which all arc components made segmental, from segment 1 until segment 13, which loaded onto pontoon, arranged by a way so that pontoon stay stabile during installing arc construction, installing bracing at the same time with arc construction accordingly following arc construction installation, stressing cable using twin ram jack unit or multi-strand M-PV to stabilize premier supporter installation of upper bridge, featured that to unite premier tower piles, we use segmental by unite on site as necessary, and knock down easily after installing premier supporter stabilization of upper bridge portion, meanwhile tower hook, tower, bearings, cable installation, and tension, as additional device by using existent pillars so that reduce duration and cost wholly.
