An automated equipment for culvert pipe production

Abstract

The invention discloses an automatic equipment for culvert pipe production, which belongs to the field of culvert pipe production equipment. The automatic equipment for culvert pipe production uses the heat of water vapor to increase the temperature of nitrogen in the expansion cavity in the link of water vapor curing, thereby increasing its temperature. Pressure and volume, use the expansion pad to press the attachment pad, and press the repair material block melted by the high temperature of water vapor, so that the repair material block penetrates into the groove on the inner wall surface of the main body of the cement culvert pipe, and then in the cooling process, on the inner wall of the main body of the cement culvert pipe A smooth protective layer is formed on the surface, and the formation of the protective layer is more uniform through the arrangement of elastic cavities, elastic balls and filling fiber clusters in the expansion pad, and the surface treatment of the inner wall of the culvert can be realized to make the surface of the culvert smooth and not easy Excessive wear is formed locally on the inner wall of the culvert, and it is not easy to cause the surface treatment layer to peel off from the inner wall of the culvert under the washing of running water, so as to ensure the normal service life of the culvert.

Description

technical field [0001] The invention relates to the field of culvert pipe production equipment, more particularly, to an automated equipment for culvert pipe production. Background technique [0002] Refers to a pipeline buried below the surface, cast with reinforced concrete, commonly known as cement pipe. Small culverts are also made of metal materials. Under the whole section of the cofferdam and dam, it is used as a water diversion pipeline, and in general, it is used as a water transmission pipeline. Most of the water supply and drainage pipelines in our country use cement pipes as culvert pipes. Compared with metal alloy pipes, cement culvert pipes have the characteristics of high strength, not easy to deform and strong corrosion resistance, and are suitable for underground and surface natural environments. It is not easy to rust and damage in the natural environment. [0003] Concrete pouring refers to the process of pouring concrete into the mold until plasticizat...

AI Technical Summary

Problems solved by technology

[0004] In the actual production process of culvert pipes, the content and quality of fine sand in the preparation raw materials, molding temperature and molding time all seriously restrict the surface roughness of culvert pipes, and the culvert pipes buried under the ground or placed on the surface are mainly used to guide life. Wastewater, culverts with rough surface will form excessive wear locally under the washing of domestic wastewater, which will lead to stress concentration of culverts at the position of excessive wear, resulting in overall fracture of culverts, greatly reducing the normal service life of culverts, and need to be re-consumed A lot of manpower and material resources to clean and replace the new culvert
