The cause of cracks on the surface of cement pipe. The cracks on the surface of cement pipe are mostly caused by folding, and the key can be divided into two categories: one is caused by the evaporation and hardening of the water on the surface of cement pipe during rigid concrete pouring. Generally, the average external temperature of cement pipe during rigid concrete pouring is high, while the air humidity in the air is low, so the surface will volatilize and dry, but the interior is still plastic, This causes cracks. The other is caused by the temperature difference between the inside and outside of the concrete caused by the water cement ratio when the cement pipe is hardened. For deeper cement pipes, the foundation will continue to settle due to its own weight during the whole process of concrete pouring of the top cement pipe. Then, when the cement pipe is exposed to building reinforcement or the connecting anchor bolt of the template and other items just before the final setting but not before the final setting, this kind of foundation settlement will be blocked and will immediately cause cracks.

Reinforced concrete cement pipes are very common in our daily life. The common places are urban underground sewage pipes and farmland irrigation pipes, which have gradually become indispensable products for urban development. However, the price of reinforced concrete cement pipes is not always the same. Many factors have a certain impact on the price of cement pipes, so why does the price fluctuate, What are the specific factors? Next, the manufacturer of Pinghu Huafeng cement pipe will explain the factors that affect the price fluctuation of reinforced concrete cement pipe.

More rigorous and standardized measures and construction steps are also proposed for the cement pipeline according to the requirements: first, the surveying and setting out work should be in the charge of a full-time surveyor, and the construction of surveying and setting out records and check filing system should be strictly implemented, using calibrated instruments. According to the design drawings and pile handover records, check the bench marks, establish temporary bench marks, do a good job of protection, and conduct closed resurvey to control the elevation. Secondly, after the trench is excavated in sections, the elevation and elevation shall be reviewed in time to control the elevation of excavation, cushion and foundation surface. Squeeze and compact the stones, remove the soil, lay the reinforcement, erect the plank, and then pour the ground.

Salt: When the concrete contacts with water with many soluble salt compounds, these salt compounds will seep into the concrete, and the salt will be continuously concentrated in the concrete and become crystalline, and the volume will often become larger during crystallization. Therefore, it will lead to cracking and damage of concrete materials, which will be corroded by sulfate. When cement pipe plants use concrete, the common form of chemical corrosion is sulfate corrosion, and sulfate reacts with vanadite in cement to produce sulphoaluminate. At the same time, it will increase, which will crack the concrete material.
