A circular assembly line production technology which includes realizing material distribution via mould core vibration, shaping via vibration of a vibrating table and maintenance via steam curing of a curing kiln is adopted, maintaining processes are performed in a multi-channel staged maintaining manner, and maintaining time, speeds of warming and cooling, heat preserving time, degree of a temperature and the like for every channel are controlled independently. The automatic production line is mechanical in the whole production process controlled automatically and is high in degree of automation.

Automatic production line for U-shaped reinforced concrete water channels

The invention belongs to the technical field of construction, and relates to a continuous cage weaving type tubular pile production line. The continuous cage weaving type tubular pile production line comprises a material distribution device, a die assembly device, a centrifugation device, a steam-curing device, a die disassembly device and a cage weaving device. The cage weaving device comprises a cage weaving machine and a steel bar end upsetting machine. A steel bar storage mechanism is arranged between the steel bar end upsetting machine and the cage weaving machine. One side of the steel bar storage mechanism is connected with the steel bar end upsetting machine, and the other side of the steel bar storage mechanism is connected with the cage weaving machine. The steel bar storage mechanism comprises steel bar storage racks. Steel bar storage rack chain assemblies capable of rotating around the steel bar storage racks in the circumferential direction are connected to the steel bar storage racks in a rotating manner. A plurality of steel bar brackets with opening parts are fixed to the steel bar storage rack chain assemblies. When the steel bar storage rack chain assemblies rotate, the steel bar brackets and the steel bar storage rack chain assemblies synchronously rotate. Steel bars coming out of the end upsetting machine can be automatically stored and conveyed to the cage weaving machine, and therefore the links of conveying and stacking the steel bars are omitted, and the work efficiency is further improved.
