How is Jiaxing cement pipe made? First of all, the items needed for the production of cement pipes: steel bars, fine aggregate concrete, seam slots, steam chambers, reinforced shelves, cement pipe molds. Manufacturing process of cement pipe: first bind the reinforcement of cement pipe on a shelf, then wrap the reinforcement cage with a special mold, then pour fine aggregate concrete from a slot, seal the slot, then turn on the motor, make the rotary shaft in the cement pipe run to drive the cement pipe to rotate, make the concrete gradually dense through centrifugal operation, and then put it into the steam chamber for curing, Take it out when the strength of formwork removal is reached.

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.

With the improvement of people's requirements for living environment, various construction measures have also raised the requirements accordingly. In the construction of drainage and sewage pipelines for urban construction, the requirements for the installation of cement pipelines have also been raised accordingly. This not only makes strict requirements on the quality and material of cement pipes, but also regulates the construction. Corresponding construction management specifications have also been formulated for the installation of cement pipelines. First of all, during installation, it is necessary to measure and set out first, and then dig trenches and earth according to the specifications of cement pipes. When laying the pipeline, the pipeline foundation construction shall be carried out first, and then the cement pipeline shall be cleaned inside the pipe, and then the concrete pouring inspection well and the anchor pouring shall be carried out. After these works are completed, the trench shall be backfilled as required.

Before the cement pipe is laid in the ground, professionals should check whether the cement pipe is in good condition and whether there are cracks. Small cracks can be repaired on the spot. If large cracks affect the construction safety, return to the factory and replace the qualified cement pipe. The foundation for pipeline laying must be strictly controlled. The cement pipe manufacturer shall be responsible for the construction and the quality department shall supervise the construction. The problems must be checked layer by layer. The problems shall not be buried underground, otherwise, the quality will directly affect the later construction, and further maintenance will consume more human and material resources. When laying the pipeline, the manufacturer's construction team shall strictly follow the construction scheme, and shall not change the construction scheme or cut corners without authorization, otherwise the hidden dangers of engineering quality left after laying will be seriously affected.

Temperature: for the solidified mortar layer or concrete component, if the cement pipe factory is often in high temperature and extreme heat conditions, there will be strength loss. This is because the calcium hydroxide in the cement stone will be separated under high temperature conditions. In addition, some aggregates will separate or expand in volume under high temperature conditions. Cement raw materials: when selecting cement, cement varieties with high strength, good durability, appropriate price and reliable quality should be selected. The cement varieties with special properties shall be selected according to the service conditions of cement pipes; It is an important condition to ensure the durability of cement pipes to select better sand and stone aggregates, and sand and stone aggregates with good quality and qualified technical conditions.

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. Cement pipes have been widely used in industrial production and urban planning and construction, and have played a key role, such as coating pipes used for drinking water, electric power engineering communication equipment, natural gas camp, etc., which must be laid underground. The quality assurance of infrastructure is the foundation of engineering construction in all big cities, so more stringent regulations must be made on the construction materials.
