Cable-stayed suspension bridge structure suitable for super long spans

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.

RIGID HANGER CONNECTING STRUCTURE AND BRIDGE STRUCTURE
20190063014 · 2019-02-28 ·

The present invention relates to the field of construction engineering, and discloses a rigid hanger connecting structure and a bridge structure. The connecting structure includes a rigid hanger and further includes a first connecting portion connected to a top end of the rigid hanger and a second connecting portion connected to a bottom end of the rigid hanger, and the hanger is connected to the first connecting portion and/or the second connecting portion by using a spherical bearing pair. In the present invention, a rotatable connection between the hanger and a bridge structure is implemented to avoid cracking of concrete inside a short hanger, prolonging the service life of a bridge; the connecting ends of the hanger are located within a line of sight range convenient for maintenance, to eliminate a blind zone, improving bridge safety; the hanger can be prefabricated in a factory, shortening construction period and improving efficiency.

LARGE-SPAN CORRIDOR STRUCTURE COMPOSED OF ARC-SHAPED CANTILEVER TRUSSES AND STAY CABLE SUPPORTING STRUCTURES AND CONSTITUTING METHOD THEREOF

A large-span corridor structure composed of arc-shaped cantilever trusses and stay cable supporting structures is provided, comprising cantilever trusses with arc-shaped facades, orthogonal connecting trusses at a corridor, connecting trusses at cantilever portions, corridor truss structures, and stay cable supporting structures; the cantilever trusses with arc-shaped facades are composed of two sets of ultra-long cantilever trusses with arc-shaped facades and triquetrous planes which are supported by ground and symmetrical, and each are set of ultra-long cantilever trusses with arc-shaped facades and triquetrous planes are formed of several ultra-long cantilever trusses with arc-shaped facades and triquetrous planes arranged in parallel at a certain distance. The beneficial effects of the present disclosure are: the large-span corridor structure composed of arc-shaped cantilever trusses and stay cable supporting structures provided serves the combination of the cantilever trusses with arc-shaped facades and the orthogonal truss at the corridor as the supporting truss core system, and the performance of lateral force resistance and torsion resistant of the overall structure can be enhanced by the connecting trusses at cantilever portions.

Module for deicing a cable sheath and method for using the same

A module for deicing a cable sheath has a mass, a vibrator, and a base. The module may be placed inside a sheath, such as a sheath surrounding stay strands in a cable stayed bridge, for vibrating the sheath to prevent and/or remove snow and/or ice accumulation from the sheath.
