What are the reasons for the formation of cement pipe damage from the production process?
When it comes to cement pipes, we are not unfamiliar. Cement pipes are a kind of prefabricated pipes manufactured by using the principle of centrifugal force of electric poles with cement and steel as data. The quality control of cement pipes includes two aspects: energy level planning control and production process control. The intention of energy level planning and control is to ensure the safety, reliability and economy of the pipe during use; the intention of production process control is to produce high quality products under reasonable process conditions. The application of cement pipes is extremely extensive. It is one of the better equipments for us, so in order to make better use of cement pipes, this article only discusses the reasons for the damage of cement pipes from the production process. It is expected to have a certain effect on cement pipe manufacturers.
What are the reasons for the damage of cement pipes from the production process?
First, analyze the reasons for the formation of cement pipe damage from the production process
1. Reasons for the unreasonable information and manufacturing process of the steel cage
During the construction of the roadbed, the cement pipe must bear the effects of compaction equipment, large cranes and other heavy machinery and material trucks without the maintenance of the road surface and the bottom layer. After the highway is opened to traffic, it also bears the repeated effects of periodic heavy vehicle loads. Especially when the thickness of the fill on the cement pipe is less than 1m, and the compaction degree of the backfill of the platform is less than 95%, the fill on the back of the culvert will have a significantly different settlement, and the cement pipe will have a greater impact when the car passes. Impact load. In addition, the current reinforced steel pipe skeleton reinforced steel bar is generally lashed. During the centrifugal vibration of the cement pipe, the steel bar is easy to loose, and the thickness of the maintenance layer of the steel bar is insufficient. As a result, the finished cement pipe cannot meet the requirements.
