Rehabilitation and Improvement Project of 69K+100 Section of Taiwan Line 7A (Phase I)

Entrusting unit : Maintenance Engineering Office of the Second District of the General Administration of Highways of the Ministry of Communications
Program Location : Heping District, Taichung City
Plan schedule : Planning and design in March 103 of the Republic of China, completed in September 106
Program Overview : 
    The project is located in the Songmao area, Heping District, Taichung City, and was affected by the concave bank erosion of the upper reaches of Dajia Creek below and the heavy rain of the typhoon, which caused the stratum to slip in the area, resulting in a subsidence of about 10m on the roadbed of the highway, and a landslide near the ridgeline. Since the Taiwan 7A line is an important road leading directly to Yilan in the north of the Lishan area, shouldering the important functions of vegetables, fruits and sightseeing transportation, after the sliding depth is determined according to the long-term monitoring results, the first phase of the drainage project and the second phase of the anti-slide pile project will be handled in stages, with a total cost of 33 million yuan for the first phase of the 3 deep water collection wells and 84 million yuan for the second phase of the anti-slide pile project.
