As an important component of cable - stayed bridge, cable tent tower has the characteristics of high cost, long construction period. It has great significance for speeding up the construction progress and improving the engineering quality and economic benefit to choose scientific and reasonable construction method of main tower. Automatic hydraulic climbing form construction method has safe, fast, efficient, and many other advantages, which is widely used in high cable tower construction. The article takes a practical engineering for example. The high cable - stayed bridge cable tower construction plan, construction technology and process are expounded. Through data statistics and analysis, the cable - stayed cable tower construction quota is calculated and compiled to provide reference for engineering cost personnel.
