On September 24, 2022, the Ruoyuan Tunnel of Taihua four-bid project, which was built by Gansu Wantai Construction Engineering Co., Ltd. was successfully started. Yang Xiaolong, deputy county head of Huachi County, Qingyang City, and the heads of the project office and the director's office attended the groundbreaking ceremony.

The total length of Taihua Four Standard project is 16.28 kilometers, the location is located in Dazhuang Village, Shanxiang Township, Huachi County, Qingyang City, and the destination is Shizuizi Village, Ruoyuan Town. The main line adopts two-way four lanes, and the design speed is 80 km/h. There are 30 Bridges with a total length of 6.19 kilometers and 3 tunnels with a total length of 1.91 kilometers. There are 5,357,500 square meters of roadbed excavation and 2,588 million square meters of filling, 1 interchange and 1 toll station. The project line is laid along the gully, with Bridges and tunnels accounting for up to 56%. Along the rainfall, bad geology and special rock and soil cause complicated geological topography, fragile ecological environment. The tunnel passes through the loess mound, and the loess overburden is prone to instability. The shortage of available block stone, flake stone, gravel and other materials along the line, the project conditions are difficult, the overall construction technology requirements are high, and the quality control is difficult.

Strong man is not afraid of mountain tiger, Yan zhi dry cloud Hushan line. At the beginning of the approach, the project department carried out a comprehensive "battlefield" survey in combination with the actual situation, elaborately compiled the "Construction and Implementation Plan of Quality Engineering for THTJ-4 Section of Heshui (Taibai) -Huachi Highway Project", coordinated the implementation of the preliminary plan, strengthened the sense of responsibility, and specialized classes to promote. At present, personnel and equipment have all entered the battle position, and 4 stations are under construction. Taihua four standard project will achieve to ensure the "flying Gold Award", "Li Chun Award", and strive to "Luban award" to create a wisdom, peace and safety of the overall goal of the quality project, inverted construction period, wall map combat, comprehensive pressure, to ensure the quality of the project progress double excellent.

Guanshan Wanli Lianxin road, autumn Hongtu wins spring tide. All the participants of Taihua Four Standard Project Department continue to strengthen the sense of mission and responsibility, and create a broad "road to prosperity" and "road to happiness" with ingenuity that can stand the test of The Times and satisfy the people of the old area.Editor/XingWentao
