Main project content:
Chiayi County Highway 157, starts from the south
side of Dahukou River in Dabi Township, Yunlin County, going southwest through
Xikou, Xingang, Liujiao and Puzi of Chiayi County, and ending at Guogou village
of Budai Township. Within the scope of this project, segment between 29Km+800 ~
30K+759 is the Suantou Bridge. The Suantou Bridge was completed in 1982. It is
more than 30 years old. The Suantou Bridge is adjacent to the Suantou National
Elementary School, the Shuangxi National Elementary School, the National Palace
Museum South Campus, the Suantou Sugar Factory Culture Park, and the Taiwan
High Speed Rail Chiayi Station. It’s the main traffic routes in the
surrounding area.
The Suantou Bridge was severely washed out in
the bridge pier in the Puzi River, the steel bars were exposed to rust, and
some of the cap beams were also damaged. The Suantou Bridge was the main bridge
between the Puzi City and Liujiao Township surrounding the Puzi County. The
width is 8.3 meters, which is a two way road with only one lane on each way.
The connecting roads at both ends of the bridge have been widened to 18 meters,
so the difference between the bridge width and road width is very large, which
has caused the safety threat and traffic jam for the passers. In addition, the
current situation of Puzi’s connecting pathway is that it’s a flood control
road which intersects with the plane of the bridge and neighboring residents
has been using it as exit and entrance, and the farmers use the road here to get
to the high wetland for farming. However, the relevant roads are intertwined
and are in mis-repair condition. The width is narrow, which is unfavorable for
agricultural machinery and equipment, and it is easy to cause safety threats.
Therefore, it is necessary to re-plan the existing connecting pathway, flood
control roads and the Suantou Bridge to solve the existing traffic problems.
The current situation of the road leading to the Suantou Road is that the
existing crossing road and the flood control road though they have no
intersection, the same that the local residents and farmers use the road to get
to work, but it does not affect the implementation of the project, only the
bridge needing to be rebuilt for widening. As mentioned above, in order to make
use of the safety of passengers and the safety of local residents, the project
will be expanded and rebuilt. After completion, the people in Puzi City,
Liujiao Township and neighboring areas will benefit directly from it.
The
Suantou Bridge spans the central pipe of the Puzi River, the old bridge is of
truss I-beam structure, and the lower 2 sides of the bridge is the highland
farming area. The reconstruction project will be equipped with a large span
steel diagonal bridge with a height of 73 meters. The total bridge length of
the 9-span pre-stressed concrete I-beam (span 43.125M) and the 2-span
continuous hollow beam structure (30M+30M) totaling 613.125M. There are a total
of 119 foundation piles in this project, except for the bridge tower foundation
pile and the P11 pile column foundation pile, which are 200∮, and the rest are
150∮. The main bridge steel structure of the Suantou Bridge is 2,951 tons, and
the cable-stayed cable is 15.2MM pre-strength steel strands (5 pairs on each
side). The project is located at the junction of Sautou Village and Puzi City
in Liujiao Township. The main bridge bridge tower is designed with vases and
LED lighting and nighttime LED floodlights. After completion, it can be used as
a new landmark for local sightseeing, becoming one of night view vista points.
