The common problem of cement pipe is erosion. The erosion problem of cement pipe mainly includes crevice corrosion and corrosion. These two erosion methods belong to diffuse erosion and are not easy to be detected by inspectors. The other kind of intergranular corrosion cracking is the pipeline cracking caused by erosion and other external effects of support force and ground stress, causing huge damage. At this time, the pipeline shall be removed and replaced in time. There is also a common problem of mechanical equipment damage. This kind of damage mainly includes chisels and pits containing chisels, which is generally caused by mechanical equipment damage. External cracks are also a problem of cement pipes. These problems belong to the plan problem and can be easily detected. Peeling is a relatively serious damage condition, and perforation will lead to fracture or leakage.

Cement pipes can be used in many fields, such as rainwater drainage, sewage drainage, industrial wastewater drainage and community drainage. As well as the buried pipelines of highways, or for protecting cables, optical cables, etc. Cement pipes have the following characteristics: 1. Generally speaking, they have rigidity, flexibility and excellent mechanical properties. And it has strong compressive properties. 2. The chemical property is stable, generally corrosion resistant, but non-toxic, and it is an excellent environmental protection pipe. 3. For the connection, as long as the flexible rubber ring is used, the street seal can work well. Long term operation. High quality, no leakage 4. The inner wall of the pipeline is flat and yellow, and the fluid friction is relatively small. If used on the ground, the service life will exceed 20 years.

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.

7) The grout is repeatedly stirred and lifted. After sinking to the design depth, the grout is repeatedly stirred and lifted until it reaches the ground. 8) The pile driver is moved. After the construction of one pile, move the pile driver to the next pile position, and repeat the above steps for the construction of the next pile. Jiaxing cement pipeline, also known as cement pressure pipe and reinforced concrete pipe, can be used as sewer pipe in urban construction, sewage drainage, flood control and drainage, as well as water supply pipes and farm motor wells used in some special factories and mines. Generally, it is divided into: plain end reinforced concrete cement pipe, flexible rebated reinforced concrete cement pipe, socket reinforced concrete cement pipe, F-shaped steel socket cement pipe, plain end ring joint cement pipe, rebated cement pipe, etc.

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.

The general defect is corrosion, which mainly includes pitting and erosion. These two corrosion modes are chronic and not easy to be found by testers. The other is stress corrosion cracking, which is caused by corrosion, tension and stress at the same time. Mechanical damage is also a defect of cement pipes, mainly including gouges and dents with gouges, which are usually caused by mechanical loss. External crack defects are plane defects of cement pipes, which are easy to be found. Peeling is a serious wear condition, and perforation will cause fracture or leakage. Therefore, cement pipes should be tested in time. Once defects are found, corresponding repair measures should be taken immediately to eliminate potential safety hazards and ensure safety.
