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.

The application of electric oil pump must refer to the manual of electric oil pump. In case of use, the requirements in the key main parameters should be followed very well. Do not be overweight. After arriving at the travel arrangement, pressure should be applied. Otherwise, when the height width ratio of lifting or the lifting tonnage exceeds the requirements, the top of the hydraulic cylinder may have serious oil leakage. Before application, be sure to check whether each part is normal, and ensure the safety factor of each rubber hose connection. With the continuous and sustainable development trend of cement pipes and the increasing number of applications, problems such as pipeline leakage of cement pipes due to design, production and manufacturing or lack of maintenance have arisen.

When planning the cement pipeline system, the slope of the cement pipeline above the overflow water level should be minimized to reduce the length of the ponding pipe section and the amount of ponding in the drainage system. The slope of the cement pipeline below the overflow water level should not be too small, and it should be ensured that the water flow has a certain scouring strength on the pipeline when the pipeline is evacuated. This method is applicable to the control point of the cement pipeline which is close to the access point of the municipal cement pipe network. If one method is adopted, the cement pipeline in the community cannot be connected to the municipal pipe network, and the residential community or factory area with small scale is also applicable to the rainwater drainage system. When used in the rainwater drainage system, rainwater is discharged through overflow wells. The rainwater pump is only opened after each rain and when the pipeline needs to be dredged and maintained, so as to remove the accumulated water in the pipeline.

When it comes to cement pipes, I believe you are no stranger. All kinds of cement pipes are widely used in daily life. However, although the cement pipe is very convenient to use, it also has a certain service life. 1. It is important to choose the type of cement. Only by selecting the type of cement that meets the requirements can the service life be increased. Therefore, the selection of raw material cement is also very critical. The selected cement type must meet the requirements in strength and fineness. Ordinary Portland cement is the best choice, and the setting time should not be too long. 2. Control the water cement ratio and cement consumption.

Cement pipe drainage pipe body has many characteristics. Its heat resistance, flame retardancy and resilience are outstanding features. It is not metal but pipe. No magnetism. Therefore, when placed in the cement tank, no vortex will occur. 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. Then the cement pipeline has the following characteristics: 1. Generally speaking, it has 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.

Bored cast-in-place pile has strong vitality because of its high bearing capacity and adaptability to complex geology. However, this pile type needs to deal with the mud pumped out during construction, which causes serious environmental pollution. It has been less used in urban construction at home and abroad, and its production cost is quite high, so it is relatively less used in general industrial and civil buildings. The advantages and disadvantages of precast concrete square piles have been described, which will not be repeated, but it is worth mentioning that its construction damage rate is very low, which is also one of the starting points for our development and production of prestressed hollow square piles; At the same time, because it is solid and has a large dead weight, cracks often appear on the pile body during construction, resulting in poor durability of the pile
