This invention relates to the field of bridge engineering technology, specifically to a wind-resistant device and construction method for the main girder of a cable-stayed-suspension bridge during construction. It includes: a first connecting part, a second connecting part, a crossbeam, and anchor cables. The first connecting part is fixedly connected to the main girder in the suspension zone, with at least two sets of the first connecting parts connected to both ends of the main girder in the suspension zone, distributed on both sides of the main girder in the suspension zone. The second connecting part is fixedly connected to the main girder in the cable-stayed zone, with at least two sets of the second connecting parts connected to one end of the main girder in the cable-stayed zone near the main girder in the suspension zone, distributed on both sides of the main girder in the cable-stayed zone. The crossbeam is connected to two main cables in the overlapping zone. One end of the anchor cable is connected to the first connecting part, passes through the crossbeam in the middle, and the other end is connected to the second connecting part. This invention can improve the wind resistance performance of the main girder in the suspension zone, and is highly targeted, has good wind control effect, and is convenient to install and apply.

The application discloses a small-diameter steel wire strand manufacturing device and method. The device comprises a wire releasing device for releasing steel wires, the wire releasing device having a fixed damping to make the released steel wires have a certain initial tension; a pair of steering devices oppositely arranged, the steel wires being reciprocally wound through the pair of steering devices; a traction device having a fixed load and being connected to and pulling the outer ends of the steel wires on the wire releasing device, the traction device pulling the steel wires to be reciprocally wound along the pair of steering devices at a rated tension until a required number of steel wires for a strand is formed; and a shaping device for shaping and compacting the multiple steel wires after winding to make the steel wires form a required shape and compacting force of the strand. The application solves the problem of manufacturing small-diameter steel wire strands of a main cable of a suspension bridge, and has the advantages of convenient installation and application, convenient operation, controllable quality, and no need of large mechanical equipment.

The application discloses a continuous feeding segmented die-casting equipment, which comprises a mold closing assembly and a die-casting assembly. The mold closing assembly comprises a machine table, a mold closing driving module, a mold closing seat, a movable seat and a fixed seat. The die-casting assembly comprises an extrusion driving mechanism, a screw driving mechanism, a pressure injection driving mechanism, a heater, a first barrel, a flow distribution module, a second barrel, a third barrel and a fourth barrel.
