Jiuma Expressway on the Plateau of Aba Tibetan and Qiang Autonomous Prefecture
Maleny High Altitude Area Mixing Station Application Technology Exchange Meeting
Jiuma Expressway is the first high-altitude plateau expressway in Sichuan Province.，Invested by Zanggao Jiuma Company of Shudao Group，Construction by Sichuan Luqiao Jiaotong Construction Group，The total length of the project is 219 km。At high altitude、Construction in alpine region，More challenging for construction personnel and equipment，Average annual temperature along Jiuma Expressway 1.4℃，Extreme minimum temperature-36℃，The temperature difference between day and night can reach 28.4℃，You can see the four seasons in one day.，The weather conditions are harsh，The temperature difference between day and night is large，The average annual effective construction period is only about 6 months.。
