    1. Detailed information

    The main tower of the second cable-stayed bridge of Tonghai Road Interchange Project in Xining Haihu New Area is 106 meters high. The overall design is a swan landscape. The lower tower column is 23 meters, which is a hollow structure of four-sided vases with 20 special-shaped cavities. External formwork fabrication completes the overall assembly, and set a stable pin between the formwork. On-site group of formwork is fast and error-free, and reasonable tension reinforcement is designed.

    The shape of the upper tower pier is complex. A universal hydraulic climbing formwork system which can adapt to the front, rear and side angles greater than 15 degrees is designed. It consists of hydraulic climbing system, formwork system and six-layer working platform system. The demoulding and closing of formwork are controlled by hydraulic pressure, so the construction is safe and convenient.
