An apparatus for de-icing the surface of a casing tube of a tendon that is exposed to weather influences, or to guard against, if not completely prevent, ice forming on the tube, where the tendon is anchored to a structure by means of an anchoring device is provided. The apparatus includes a power device, one end of which is in force transmitting engagement with the anchoring device or with a part that is connected to the anchoring device in an operationally stable manner, and the other end is in force transmitting engagement with the casing tube or with a part that is connected to the tube in an operationally stable manner. The power device is configured to move the casing tube relative to the anchoring device in the circumferential, radial and/or axial direction in relation to the longitudinal extension direction of the casing tube.

A cable-stayed suspension bridge structure suitable for super long spans by comprising a horizontally arranged main bridge main beam, wherein vertical main towers are arranged at ends of the main bridge main beam, and each main tower is anchored by stay cables; a main bridge vertical support and a longitudinal elastic damping stopper are arranged at positions of the main bridge main beam close to the main tower, and the main beam is kept stable longitudinally by virtue of the geometric stiffness of the cable force of the stay cable and the longitudinal elastic damping stopper.
