The invention relates to a road bridge expansion construction line-crossing protection structure and a construction method of the protection structure and belongs to the technical field of road bridgeconstruction equipment. The road bridge expansion construction line-crossing protection structure comprises an existing road bridge with an anti-collision wall. Two supporting columns are arranged onone side of the existing road bridge and located on the two opposite sides of a crossed road section. A formed prefabricated crossbeam is transversely arranged between the supporting columns. An auxiliary frame is arranged on the side, close to the anti-collision wall, on the upper end face of the prefabricated crossbeam and arranged in the length direction of the prefabricated crossbeam. The cross section of the auxiliary frame is in a y shape. The end face, close to the anti-collision wall, of the auxiliary frame is attached to the anti-collision wall. The auxiliary frame fixedly connectedwith the prefabricated crossbeam is adopted for stopping slag materials falling, wooden boards and waterproof cloth in the prior art are saved, material use cost is reduced, the auxiliary frame and the prefabricated crossbeam are formed at the same time, the labor working procedure number of construction personnel is reduced, the outdoor workload of workers is reduced as well, and the work environment and the work condition of the workers can be improved.

The invention belongs to the technical field of building formwork manufacturing equipment, and relates to punching equipment for lateral rib plates of building formworks, in particular to building formwork machining equipment capable of achieving automatic adjustment and punching multiple holes at a time. In the equipment, pressure is transmitted through oil pressure cavity and piston combination,so that manufacturing becomes easy; a large hydraulic cylinder is shared to provide blanking driving force, so that the manufacturing cost is greatly reduced. Operation of the equipment also becomeseasy, it is only needed to regulate a control program in advance, it is unnecessary to electrify two-position two-way solenoid valves corresponding to punching positions, and punching can be completedwithout electrifying the two-position two-way solenoid valves corresponding to the punching positions; compared with a punching mode requiring punching pin detachment, the working process is greatlysimplified, the workload is greatly reduced, and use is easy and convenient. Compared with a production mode with holes punched one by one, the working efficiency is greatly improved, and the distanceprecision of holes is greatly improved.

The invention discloses a niblet classifying and screening device.
