What is pumped concrete
Pumping concrete is a modern construction technology that transports concrete to the construction site through concrete pumps and conveying pipes. It is widely used in high-rise buildings, bridges, tunnels and other projects, and can effectively improve construction efficiency and reduce labor intensity. The following is a detailed introduction to pumped concrete.
1. Definition of pumped concrete
Pumped concrete refers to the construction method in which premixed concrete is transported to a designated location through the pipe through the pressure of the concrete pump. This technology is especially suitable for large-volume concrete pouring, high-rise buildings or construction scenarios where manual transportation is difficult.
2. Advantages of pumping concrete
| advantage | illustrate |
|---|---|
| High construction efficiency | The pumping speed is much faster than traditional manual transportation, greatly shortening the construction period |
| Save labor costs | Reduce the number of transport workers and reduce labor costs |
| Strong adaptability | Can be transported to high altitude, long distances or complex terrain areas |
| Stable quality | Reduce concrete separation phenomenon and ensure pouring quality |
3. Technical points of pumping concrete
| Technical Highlights | Specific requirements |
|---|---|
| Slump control | Generally controlled between 80-180mm, it is easy to be separated if it is too large, and it is easy to be blocked if it is too small. |
| Aggregate particle size | The maximum particle size does not exceed 1/3 of the pipe diameter |
| Pumping pressure | Set reasonably according to the conveying distance and height |
| Pipeline layout | Minimize the number of elbows to avoid sharp bends |
4. Frequently Asked Questions and Solutions for Pumping Concrete
| question | reason | Solution |
|---|---|---|
| Bullet pipe | Too small slump and poor aggregate grading | Adjust the mix ratio and add an appropriate amount of pumping agent |
| Separation | The slump is too large and the conveying speed is too fast | Control slump and reduce conveying speed |
| Excessive pump pressure | Pipeline blockage, too long conveying distance | Check the pipeline and pump in sections if necessary |
5. Application scenarios of pumped concrete
Pumping concrete technology is widely used in modern construction projects, mainly including:
1. High-rise buildings: Solve the problem of high-altitude concrete transportation
2. Large-scale infrastructure: such as bridges, tunnels, dams, etc.
3. Underground projects: subway, underground garage, etc.
4. Special terrain projects: construction environments such as mountainous areas, waters, etc.
6. Development trend of pumped concrete
With the continuous development of construction technology, pumping concrete technology is also constantly innovating:
1. Ultra-high-rise pumping technology: breaking through the height limit of more than 600 meters
2. Intelligent control: adopt sensors and automatic control systems
3. Environmentally friendly pumping: reduce noise and dust pollution
4. New material applications: Development of higher performance pumping agents
7. Recent industry hot spots
According to industry trends in the past 10 days, hot spots in the field of pumping concrete include:
| Hot content | Brief description |
|---|---|
