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.

Maintenance means no steam curing tank. After the cement pipe is made on the cement pipe making machine, it is not necessary to open the grinding tool. Put the cement pipe mold and cement pipe outdoors for regular maintenance. Generally, after the cement pipe is made, it takes one day to carry out outdoor maintenance. The grinding tool can be opened the next day. After the mold is made, it also needs to carry out 4-6 days of regular maintenance, and full-time personnel should spray water on the cement pipe three times a day, The time of sprinkling is usually once in the morning, once in the afternoon and once at noon. The purpose of sprinkling is to maintain the environmental humidity of the cement pipe so that the concrete can gradually coagulate itself. The frequency of sprinkling can also be increased and reduced according to the environmental humidity of seasonal changes in weather conditions. But of course, there are more cement pipe molds required for maintenance.

1. The principle of overflow well discharge method: the sewage is mainly discharged into the municipal sewage pipe through the overflow well, and the pump is used as a supplement to remove the accumulated water in the overflow well and the upstream sewage pipe. The flow should be confirmed by discharging all accumulated water within 30min. In order to reduce the operation cost, the sewage pump can be started before the peak water consumption every day to drain the accumulated water in the overflow well and the upstream pipeline. This can not only prevent sewage from staying in the pipeline for a long time and forming siltation, but also make the ponding pipe section often washed, which is conducive to pipeline ventilation and the removal of harmful gases in the pipeline.

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.
