Description

TECHNICAL FIELD

[0002] Concrete is a commonly used building material, which has the advantages of abundant raw materials, low price, simple production process, high compressive strength and good durability. In civil engineering, concrete has good durability and strength, and can be used to build various types of buildings and structures, including houses, roads, bridges, tunnels, water conservancy projects, etc.

[0003] The concrete precast slab is a concrete prefabricated part produced in advance in a factory, which is mainly made by pouring concrete in a mold. In the existing precast slab production and processing process, a pouring pipe is usually directly used to send concrete to the mold, and the concrete is diffused in the mold by using the flowability of the concrete itself. The feeding mode is relatively concentrated and cannot achieve uniform feeding, resulting in less concrete around the mold, and defects are prone to occur around the precast slab after molding. Although the staff will use a plate-shaped vibrating device to vibrate and smooth the top of the concrete in the mold after the overall pouring is completed, which can effectively eliminate the air bubbles in the upper layer of concrete, the vibrating mode is difficult to effectively vibrate the internal concrete, and there are many air hole defects in the molded precast slab, the compaction effect of the concrete is poor, and the quality of the finished precast slab is poor.
