Summary:
Pipe blockage is one of the most common malfunctions in wet‑spraying rig operations, significantly compromising construction efficiency and increasing equipment wear. By implementing systematic preventive measures, the incidence of pipe blockages can be effectively reduced, ensuring operational continuity and cost‑effectiveness.
I. Optimization of Concrete Mix Proportions
Scientific design of material mix proportions and formulation parameters:
1. Cement dosage is controlled at 380-450kg/m ³, ensure sufficient slurry volume
2. The sand ratio is maintained at 50%-55% , fineness modulus 2.3-2.8
3. The nominal maximum size of coarse aggregate shall not exceed 15mm , continuously graded
4. The water-cement ratio is strictly controlled at 0.4-0.45 Within the scope
Selection and Rational Use of Functional Admixtures:
Add a high-efficiency water-reducing admixture to decrease the water content.
Use plasticizers to improve workability.
Add a viscosity modifier to control flowability.
Add an appropriate amount of air-entraining agent (air content 3%-5% )
II. Equipment Operating Procedures
Pump parameter settings: Properly configure operating parameters.
The initial pumping speed is controlled at 10-15m ³ /h
Adjust pumping pressure according to the delivery distance.
Maintain a steady pumping rhythm.
Avoid frequent speed changes.
Key monitoring points during equipment status surveillance and operation:
1. Closely monitor changes in pressure readings.
2. Monitor the operating sounds of the device
3. Observe the trend of oil temperature changes.
4. Check the operating condition of the lubrication system.
III. Pipeline System Management
Pipeline Layout Optimization: Scientific Planning of Pipeline Systems:
Minimize the number of bends and the bend angles.
Using large-radius bends ( R ≥ 1m )
Avoid abrupt changes in pipe diameter and sharp bends.
Regularly inspect the pipeline for wear and tear.
Pipeline Maintenance and Upkeep: Routine Maintenance of Pipeline Systems:
1. Thoroughly clean the pipelines after each operation.
2. Regularly inspect pipeline sealing.
3. Replace severely worn pipe sections promptly.
4. Keep the inner wall of the pipeline clean and smooth.
IV. Process Improvement
Startup and Shutdown Operating Procedures: Precautions for Equipment Startup and Shutdown:
Before starting up, pump mortar to lubricate the pipeline.
Perform a reverse pump before shutdown. 2-3 an itinerary
Avoid starting under load and emergency stops.
Piping must be cleaned when the system is shut down for an extended period.
Fault prevention and response measures for handling abnormal situations:
If the pressure rises abnormally, immediately perform a reverse pump operation.
Detect concrete segregation and make timely adjustments.
If unusual noises occur, stop the machine immediately and perform an inspection.
Establish a rapid response and handling mechanism.
V. Maintenance and Servicing System
Daily Inspection Checklist: Mandatory Items for Each Shift:
Check S Flexibility of valve and pipe oscillation
Confirm the clearance between the wear plate and the cutting ring.
Inspect the piston crown for wear.
Verify the operating condition of the lubrication system.
Regular Maintenance Plan: Systematic Maintenance Schedule:
1. Inspect the delivery cylinder for wear monthly.
2. Quarterly replacement of wear parts
3. Semi-annual maintenance of the hydraulic system
4. Annual Comprehensive Maintenance
VI. Personnel Training Management
Operational skills training enhances the competencies of operators:
Master the equipment’s performance parameters.
Familiar with operating procedures
Capable of fault identification
Master emergency response procedures.
Establish a well‑structured management system and a standardized management framework:
1. Develop standard operating procedures
2. Establish a quality accountability system.
3. Implement performance appraisal
4. Improve the training records.
VII. Application of Technological Innovation
The intelligent monitoring system employs advanced monitoring technologies:
Install a real-time pressure monitoring device.
Configure the automatic traffic detection system.
Set the pipe blockage early warning function.
Enable remote fault diagnosis
Equipment improvements and upgrades continuously optimize device performance:
1. Improvement S Valve and Pipe Structural Design
2. Optimize hydraulic system parameters
3. Enhance filter system performance
4. Enhance system reliability
Conclusion
Reducing the risk of pipe blockages in wet‑spraying rigs requires a systematic approach across multiple stages, including material control, equipment operation, and maintenance management. By establishing a robust preventive framework, rigorously enforcing operating procedures, and strengthening equipment maintenance and upkeep, pipe‑blocking incidents can be effectively minimized. It is recommended to develop comprehensive operation and maintenance protocols, enhance technical training for personnel, maintain detailed equipment‑operation records, and continuously refine improvement measures. At the same time, emphasis should be placed on capturing practical experience and fostering technological innovation, thereby elevating equipment‑management standards and providing reliable support for construction projects.
