Description

Technical Field

[0001] The invention relates to the technical field of pier column concrete on-site vibrating equipment, in particular to an automatic vibrating device for pier column concrete used in bridge construction. Background Art

[0002] The pouring of bridge piers usually includes the following steps, especially when vibrators are used: Formwork preparation: Design and make concrete pier formwork to ensure accurate dimensions and stable support to maintain the verticality and flatness of the structure. The surface of the formwork may need to be coated with a release agent to reduce the adhesion between the concrete and the formwork. Concrete pouring: Pour the prepared concrete mixture into the formwork according to the design requirements. Concrete pouring should be carried out from bottom to top to ensure continuity and avoid cold bridges. Use a flat vibrator to vibrate point by point along the perimeter and center of the formwork to ensure that the concrete is evenly distributed. Vibration operation: Use a vibrator to vibrate from the bottom up according to the project requirements and construction process. The key is to ensure that each point vibrates for a long enough time, but avoid excessive vibration to avoid damaging the concrete structure. For large-volume piers, it may be necessary to use a vibrator in sections, such as partition vibration or use a vibrating table. Interval and curing: After completing the initial vibration, ensure that the concrete surface moves horizontally and that not too much concrete flows out when the vibrator is inserted. During the vibration process, the outer diameter of the pier should be continuously checked to ensure that its size is controlled within the allowable range. After vibration, the concrete should be allowed to settle properly and stand still, and then cured according to the standard curing time of concrete. Curing: Use special curing equipment for moisture curing.

[0003] Due to the high height of the pier, it is necessary to pour in layers. Currently, during the layered pouring, the crane installs the hanging box on the top of the support formwork. When the specified amount is poured into the support formwork, the workers lower the hanging box and carry vibrating rods to the concrete surface. Then the workers step on the steel cage to perform manual vibration operations. The entire vibration process requires a lot of labor from the workers, the vibration cycle is long, and there are major safety hazards. Summary of the invention
