With the arrival of the scientific, information-based and digital era, the weighbridge is an important measuring instrument in the field of commerce and trade. How much impact does the foundation of the weighbridge have on the weighbridge? The weighbridge is used to weigh the weight. The important thing of the weighbridge is balance. The accuracy of the weighbridge will be easily affected if the foundation is not well done. Second, the foundation hardness is not enough, which will lead to serious consequences, such as foundation burst, foundation subsidence and a series of problems. The third drainage channel is not well done. If the drainage channel is not well done in the southern thunderstorm season, it is easy to have water accumulated in the foundation pit, causing the sensor to be damaged by long-term immersion in water.

Xiajiangmen Electronic weighbridge manufacturer Let's introduce how to construct the weighbridge foundation to ensure the quality of the weighbridge foundation.

The weighbridge foundation must be poured with concrete foundation, which must be excavated below the local frozen soil line. During the construction, the concrete grade shall be guaranteed, and the geometric dimensions such as levelness and position of the embedded parts shall be guaranteed. When pouring concrete, the embedded parts shall not be displaced. After the foundation pouring is completed, it shall be cured according to the civil engineering specifications. Only when the concrete reaches the design strength index can the weighbridge be installed. If the curing period is to be shortened, it is allowed to add "early strength agent" and other measures under the guidance of professional technicians during construction.

Construction materials: cement, medium sand or coarse sand, sand silt content not more than 5%, ordinary rubble, crushed stone

Main tools for construction: shovel, scraping bar, vibrating rod, etc

Pre construction conditions: the foundation axis size, base elevation and geological conditions have been inspected; The installed formwork shall meet the requirements after inspection; Mark the leveling of concrete on the formwork.

Construction process:

1. Site leveling

2. Surveying and setting out, foundation excavation: the weighbridge foundation must be excavated below the local frozen soil line

3. Drainage and trunking reserved

4. Erect rebar of different sizes according to different stress positions

5. Fixed size formwork installation to prevent mortar explosion

6. Pour high grade concrete, and use vibrating rod to hit

7. Concrete mixing: concrete mixing → concrete pouring → concrete vibration → concrete curing.

8. For concrete mixing, the feeding sequence is gravel → cement → sand → water, the water consumption is strictly controlled, the mixing is uniform, and the mixing time is generally not less than 90s.

9. After the concrete is vibrated and compacted, the surface shall be leveled with a wooden rod and rubbed with a wooden trowel.

10. Formwork removal and trimming

11. Check whether the drainage pipe and the wiring pipe of the weighing room are unblocked

12. After the concrete is poured and leveled, it shall be covered and watered in about 12 hours, and the watering times can keep the concrete wet enough.

It is important to remind that the weighbridge foundation must be constructed in strict accordance with the drawings to ensure that there is no deviation between the foundation size and the weighbridge size and key points.
