Cement grouting pump for rotary jet pile construction
Cement grouting pump is mainly used to inject high-pressure grouting materials such as cement slurry into the formation, in order to achieve the purpose of reinforcement, waterproofing or improving the bearing capacity of the formation. In the construction of rotary jet grouting piles, the grouting pump needs to meet different flow rate, pressure, and stability requirements according to the number of pipelines (single pipe, double pipe, triple pipe).
Cement grouting pump in the construction of single pipe rotary jet pile
For the construction of single pipe rotary jet grouting piles, the cement grouting pump is mainly responsible for injecting cement slurry from a single pipeline into the formation. This type of grouting pump usually has high pressure and stable flow output to ensure that the cement slurry can fully penetrate into the formation. The construction of single tube rotary jet grouting piles is relatively simple, and the performance requirements for grouting pumps are also relatively low.
Cement grouting pump in the construction of double pipe rotary jet pile
The construction of double pipe rotary jet grouting piles requires the simultaneous injection of two media (such as cement slurry and compressed air), so the grouting pump system needs to be more complex. The cement grouting pump needs to be combined with auxiliary equipment such as an air pump to ensure that the two media can be injected into the formation simultaneously according to the predetermined ratio and flow rate. This type of grouting pump needs to consider the synchronization and coordination of dual pipelines in its design to ensure construction effectiveness.
Cement grouting pump in the construction of triple pipe rotary jet pile
The construction of triple pipe rotary jet grouting pile is the most complex type of rotary jet grouting technology, which simultaneously injects three media: cement slurry, compressed air, and water. Therefore, the required cement grouting pump not only needs to have the characteristics of high pressure and large flow rate, but also needs to be closely coordinated with auxiliary equipment such as air pumps and water pumps to achieve synchronous injection of the three media. This type of grouting pump has high technical difficulty and cost in design and manufacturing, but it can significantly improve the construction efficiency and quality of rotary jet grouting piles.
Cement grouting pumps play an important role in the construction of single, double, and triple pipe rotary jet grouting piles. Selecting appropriate grouting pump equipment according to construction requirements and configuring supporting equipment reasonably is the key to ensuring the quality and efficiency of rotary jet grouting pile construction. With the continuous progress and development of engineering technology, the performance and intelligence level of cement grouting pumps will also continue to improve.
