Project for reconstruction on 41K of Urban Road No. 172, Baihe District (Rock shed project)
Published :

The rock shed project on Urban Road No. 172 towards Baihe District’s Guanziling, was initiated after strong winds and torrential rain from Typhoon Soulik in July 2013 caused the section neighboring 41.5K of Urban Road No.172, the main access road to Guanziling, to be blocked due to a mudslide, causing inconvenience to road users and affecting the business of the shops. Since October 1, 2013, Tainan City Government has taken back the maintenance of urban roads from the Directorate General of Highways (DGH). To thoroughly improve the safety of traffic on the road and to follow Mayor Lai’s instruction to “permanently prevent collapse”, experts were gathered to carry out multiple surveys; the decision was made to improve it following the standards adopted for Alishan Highway’s rock shed. The project was funded by the government’s disaster reserve, and it is the first rock shed for Tainan City.

Zheng Sheng Engineering & Construction Co., Ltd. was responsible for the planning, design and supervision of the rock shed project (i.e. the reconstruction project for the Urban Road No.172 from 41K+480 to 41K+570 in Baihe District). The major works include the main project and the lower part of the slope. The main project involved building a 8-meter-wide and 110.9-meter-long rock shed, while the lower part of the slope included collision preventing surface, cantilever retaining wall, headrace channel and one catchment well. Total funds for the project were NTD 69,321,000. The project was undertaken by Shan Qing Construction Co., Ltd.; it began in February 14, 2014 and was completed in February 12, 2015.

The rock shed is able to prevent mudslides from blocking the road when heavy rains occur in the future, ensuring the safety of the main access road towards Guanziling, as well as promoting Baihe District’s tourism.
