[0002] Cement culvert (also known as concrete culvert or reinforced concrete culvert) is an important infrastructure component widely used in water conservancy projects, road construction, agricultural irrigation and other fields. They are mainly used to guide water flow through underground passages, ensuring that water can be safely and effectively transported while protecting ground structures from erosion and damage.

[0003] When the cement culvert is used, it is usually transported by using a lifting device. However, if the lifting rope is directly passed through the inside of the culvert for lifting during transportation, it is easy to cause the culvert to crack and damage due to the pressure of the lifting rope. In addition, the culvert usually needs to be transferred during use. Because the size of the culvert is large, it needs to be transported by using a lifting machine. After the culvert is installed, it is easy to cause the culvert to crack and damage due to the impact of the gravity of the soil during backfilling. Therefore, we propose an anti-cracking cement culvert. SUMMARY
