Installing concrete weighbridges, whether surface-mounted or pit-mounted, requires careful planning, appropriate equipment, and precise execution of each step. Surface-mounted weighbridges are suitable for faster and simpler installations, while pit-mounted weighbridges are preferred for permanent installations and better protection against environmental conditions. By following these steps and paying attention to detail, you can ensure the high accuracy and efficiency of the road weighbridge.
Surface-Mounted Concrete Weighbridge Installation Process
1. Site Preparation:
-
A. Site Selection:
- Location Scouting: Choose a location with easy access to main roads and sufficient space for vehicle entry and exit.
- Environmental Assessment: Ensure there are no underground obstacles such as water pipes, gas lines, or electrical cables.
-
B. Ground Preparation:
- Land Leveling: Use heavy machinery to level and smooth the ground surface.
- Compaction: Compact the ground using heavy rollers to create a solid base and prevent settling.
2. Foundation Construction:
-
A. Foundation Excavation and Preparation:
- Foundation Excavation: Dig a pit with appropriate depth and dimensions for the foundation. These dimensions should be specified according to the weighbridge’s technical drawings.
- Drainage: If necessary, install drainage systems to prevent water accumulation under the weighbridge.
-
B. Reinforcement Installation:
- Rebar Placement: Place reinforcing bars (rebar) in the foundation to strengthen the concrete structure.
- Rebar Tying: Tie the rebar together with steel wire to create a unified and resistant structure.
-
C. Concrete Pouring:
- Foundation Concreting: Fill the pit with ready-mix concrete and compact it to prevent air bubbles.
- Concrete Leveling: Use leveling tools to create a smooth and even surface.
- Concrete Curing: Keep the concrete moist for several days to increase its strength and prevent cracking.
3. Platform Installation:
-
A. Platform Placement:
- Platform Transport: Use cranes and heavy equipment to transport and place the platform on the foundation.
- Platform Leveling: Use leveling tools to ensure the platform is level.
-
B. Load Cell Connection:
- Load Cell Installation: Place the load cells in the designated locations under the platform and connect them to the weighbridge structure.
- Cabling: Connect power and data cables to the load cells and route them to the display and controller systems.
4. Electronic System Installation:
-
A. Display and Controller Installation:
- Display Placement: Install digital displays in suitable and accessible locations.
- Load Cell Connection: Connect the load cell cables to the displays and controllers.
-
B. Connection Check:
- Electronic System Testing: Check and test all electronic and electrical connections to ensure proper operation.
- Troubleshooting: Resolve any potential issues and ensure the systems are functioning correctly.
5. Calibration and Testing:
-
A. Initial Calibration:
- Standard Weights: Use standard weights to calibrate the load cells and measurement systems.
- Precise Adjustments: Precisely adjust the electronic systems to ensure measurement accuracy.
-
B. Performance Testing:
- Vehicle Testing: Test the weighbridge with real vehicles to check accuracy and performance under real-world conditions.
- Reporting: Prepare detailed reports of the test results and make final adjustments.
Pit-Mounted Concrete Weighbridge Installation Process
1. Site Preparation: (Same as Surface-Mounted)
2. Pit Excavation and Foundation Preparation:
-
A. Pit Excavation:
- Pit Digging: Dig a pit with appropriate depth and dimensions according to the technical drawings. The pit depth should be such that the weighbridge platform is level with the ground surface.
- Drainage: If necessary, install drainage systems to prevent water accumulation under the weighbridge.
-
B. Foundation Preparation:
- Pit Base Preparation: Fill the pit base with a layer of gravel and sand and compact it to create a solid base.
- Rebar Installation: Place reinforcing bars (rebar) in the foundation to strengthen the concrete structure.
- Rebar Tying: Tie the rebar together with steel wire to create a unified and resistant structure.
-
C. Concrete Pouring: (Same as Surface-Mounted)
3. Platform Installation:
-
A. Platform Placement:
- Platform Transport: Use cranes and heavy equipment to transport and place the platform inside the pit.
- Platform Leveling: Use leveling tools to ensure the platform is level.
-
B. Load Cell Connection: (Same as Surface-Mounted)
4. Electronic System Installation: (Same as Surface-Mounted)
5. Calibration and Testing: (Same as Surface-Mounted)
