Another is artificial intervention, which is called macro-control in economics. This is mainly the measures taken by relevant government departments when the commodity price fluctuates greatly during this period. Just like buying a house a long time ago, the house price is too high for most people to afford, so the government may need to take measures to regulate the house price to return it to a normal curve. Another possibility is monetary policy, which is mainly due to the fact that the central bank has carried out some regulation against the situation of too intense price fluctuations.

2、 Why the price of reinforced concrete cement pipe fluctuates. In economics, an important factor affecting the price is people's demand for this product. This is an important factor. When the demand is greater than the supply, the supply falls short of demand, and the price will naturally rise; But when the demand is less than the supply, when the supply exceeds the demand, the price will naturally decline, but the rise and decline will not be too high or too low. The higher the value, the higher the price. The lower the value, the lower the price. This supply is affected by many factors.

Solution to surface crack of cement pipe. First of all, we should reasonably control the temperature raising speed inside the cement pipe. We can add appropriate mineral ash in the production of cement pipe to ease the release rate of water binder ratio; Secondly, by controlling the temperature of raw materials, we can select a condenser inside the cement pipe structure to cool the circulating water and release the specific energy of water glue. When cracks have already appeared, people usually paint cement mortar or low viscosity polymer for sealing to avoid water intrusion; If the crack is deep or wide, the working pressure grouting shall be used for technical repair.

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.

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. Then the block stones are pressed and compacted, the soil is removed, the reinforcement is laid, and the plank is erected Re pouring place.
