Atlas MEYCO Copco shotcrete technology and equipment introduced economic advantages
Atlas MEYCO Copco shotcrete technology and equipment introduced economic advantages
First, the concrete spraying process includes dry spray and wet spray
Dry jet working principle: rotor type equipment
Dry mixing soil
Dry by gravity into the rotor cavity (circular or fan-shaped hole)
The rotor rotates, and the material enters the delivery pipe under the action of compressed air
Compressed air passes the material into the feed pipe and is ejected from the nozzle
Wet spray working principle: double plunger pump and S pendulum pipe
Precast wet concrete hopper
The concrete flows through gravity and is sucked into the cylinder
The hydraulic cylinder draws the concrete into the pipeline and is ejected from the nozzle
S swing tube switching between two cylinders

Three: determine the key factors of high quality concrete injection
1. Continuity of concrete flow
2. Accurate measurement of accelerator
3. Proper compressed air volume
4, conveying and nozzle system
5, nozzle angle and injection distance
6. Pretreatment of operation surface
7. Temperature of concrete and accelerator
8. Ensure the data record function of quality management
Four, MEYCO SUPREMA introduction
Uneven concrete injection: the switching between two cylinders is bound to reduce the amount of concrete, the majority of the jet machine S swing tube switching time is 0.3-0.4 seconds
MEYCO SUPREMA has the compensation function, through the short time to improve the working speed of the cylinder / concrete output to achieve the nozzle of a uniform amount of concrete injection, S swing tube switching time is 0.25-0.08 seconds.
1. Accuracy of measuring system
Integrated metering system includes metering pump, PLC control system level closed loop flowmeter
The screw rod (rotor stator pump) ensures the continuous flow of the liquid accelerator
Control accurate measurement
High quality flowmeter
With the keyboard display window, you can input measurement parameters, such as the amount of accelerator, additives, concrete injection volume, etc.
2, compressed air and nozzle system
compressed air
Pipe plugging / pressure: pipeline diameter
MEYCO equipment uses the largest diameter pipeline (100mm) in the market, with high productivity and low wear
Safety factors: pressure release at the nozzle and automatic reverse pump
3. Injection angle and injection distance:
The nozzle is perpendicular to the jet surface
Recommended jet distance is 1.5m
The injection order is from the bottom to the top
Spray with nozzle swing mode
4. Pretreatment of working surface
Using compressed air and water to wash the surface through the nozzle
Low impact surface prying with high pressure water pump
5. Data recording system
Data recorder records work data, system information and faults
It is a simple method of admixture and concrete precise monitoring
Data analysis and report generation software
Important means of quality control
