There are various types of grouting pipes to meet the needs of different projects. The following are some commonly used grouting pipe models:
1. Classification by diameter
Φ20mm grouting pipe:
Suitable for some small or specific grouting projects, with a smaller diameter, which is convenient for operation in narrow spaces.
Φ25mm grouting pipe:
One of the more commonly used models in pile foundation projects, with a moderate diameter, suitable for a variety of grouting needs.
Φ32mm grouting pipe:
Also a commonly used model in pile foundation projects, with a diameter slightly larger than Φ25mm grouting pipe, it may have higher grouting efficiency and stronger bearing capacity.
Φ42mm, Φ48mm, Φ50mm, Φ60mm grouting pipe:
These types of grouting pipes are also used in specific projects, but may not be as common as Φ25mm and Φ32mm grouting pipes.
2. Classification by nominal diameter
DN25 grouting pipe:
Indicated by DN (nominal diameter), it is commonly used in pile foundation grouting projects.
DN32 grouting pipe:
It is also expressed in DN (nominal diameter) and is also commonly used in pile foundation grouting projects.
3. Other classification methods
In addition to classification by diameter and nominal diameter, grouting pipes can also be classified according to material, connection method, number of uses, etc. For example, there are steel grouting pipes, PVC grouting pipes, etc.; there are connection methods such as threaded connection and flange connection; there are disposable grouting pipes and repetitive grouting pipes, etc.
4. Selection of grouting pipes
When selecting grouting pipes, in addition to considering the model, the following factors need to be considered:
Grouting pressure: The grouting pipe must be able to withstand the expected grouting pressure to ensure the grouting effect.
Geological conditions: The selection of grouting pipes should consider geological conditions, such as the strength and permeability of the soil layer.
Construction conditions: The length and diameter of the grouting pipe should meet the specific needs of the construction site.
Economy: On the premise of meeting the use requirements, the selection of grouting pipes should consider economy and practicality.
In summary, there are many types of grouting pipes, and the selection should be comprehensively considered according to the specific project needs.
