Application of Construction Technology of Sliding Form Paver for Curb Stones

Traditional curbstone construction involves laying prefabricated curbstones on the base layer, which has the disadvantages of slow construction, large site occupation, and easy environmental pollution; The sliding form construction of curbstones uses a sliding form paver to spread the concrete of the curbstones on the base layer in one go, which can effectively solve the shortcomings of traditional construction.

The Judan Expressway project adopts both traditional and sliding formwork techniques for curbstone construction, and the advantages of sliding formwork construction are demonstrated through comparison; At the same time, summarize the technical scheme and quality control measures for sliding formwork construction of curbstones from the aspects of equipment configuration, material selection, construction technology, etc The curbstone sliding mode paver is an engineering machinery that uses specific molds to lay various shapes of curbstones. It is widely used in the construction of curbstones on both sides of roads, water barriers, and agricultural irrigation and drainage channels

Construction steps and precautions for the equipment of the curbstone sliding form paver: 1. Construction layout: Measurement and layout shall be carried out on the completed upper layer, with each control pile at 10 meters for straight sections and 5 meters for curved sections. The quality requirements and allowable deviations for measurement and layout should comply with the specifications. 2. Placing the curbstone forming machine: Align the pointer at the front of the machine with the placed measuring line, ensuring that the machine walks along the placed line position. 3. Mixing and transportation of asphalt mixture: The asphalt mixture is produced at a mixing station and transported by a 25T dump truck. 4. Loading: The loader cooperates with manual loading, and the dump truck unloads the material in two stages into the shovel truck. The shovel truck follows the machine in reverse, and the hot material inside the shovel is manually placed into the material truck. The machine can automatically move forward by squeezing the material through the mixer truck.

5. Traction: Swing the traction rod left and right to keep the pointer of the moving machine on the marking line, to ensure that the line shape is the same as the layout. 6. Follow the machine: Clean the surface of the machine and adjust the four small wheels of the machine according to the product turning results to ensure that the cross-sectional rules meet the standards. When encountering an emergency situation, timely pull the clutch to stop the stirring cage from rotating. After handling it, resume operation. 7. Cleaning: Three people each take iron shovels and brooms and follow behind the machine to clean up the material scattered during the loading process. When encountering a rapid flow channel, the water inlet part is shoveled off.
