1、 Distribution principle:

1. The land use within 1000 meters of the monitoring point is relatively stable;

2. The horizontal plane around the monitoring point should ensure a capture space of 270 ° or more. If the monitoring point is close to a building, there should be a free space of 180 ° or more in the horizontal plane around the monitoring point;

3. The environmental conditions around the monitoring point are relatively stable, and the location conditions need to be long-term stable and sufficiently solid, with safety and fire prevention measures guaranteed;

4. There is no strong electromagnetic interference or oscillation source near the monitoring point, and there should be stable lightning protection equipment around as much as possible;

5. It should be considered that the monitoring points have unobstructed and convenient access channels and conditions for maintenance;

6. The height of the monitoring point sensor should be within 2-5 meters above the ground;

7. There are no obvious fixed pollution sources within 50 meters around the monitoring point;

8. When installing meteorological stations on non customized monitoring poles, the load-bearing capacity of the foundation poles should be considered;

9. Monitoring points should be located in areas with sufficient sunlight (with daylight hours of at least 6H) or in areas with stable and reliable AC220V power supply.

2、 Point confirmation

After selecting the points, mark them on the monitoring area plan. Submit the floor plan with monitoring point orientation markers to Party A for confirmation and signature.

3、 Construction

1. Pre embedded monitoring pole ground cage

1) According to the actual geological conditions on site, the pre embedded pit for the monitoring pole foundation will be constructed manually with the assistance of excavators. The size of the pre embedded pit is 100cm (length) * 100cm (width) * 100cm (depth). If over excavation occurs, it is not allowed to use abandoned soil for on-site backfilling. Instead, crushed stone or sand should be used to backfill to the design value. The pre buried pit edge should be aligned in the direction of due south and due north;

2) The thread of the embedded part should be raised vertically in the pit, and concrete (cement: sand=1:3) should be filled into the pit until it is slightly above the ground level;

3) According to the season and local climate environment, air dry for about 3 days until the cement foundation solidifies and the pre embedding is completed.

2. Equipment installation and standing of monitoring poles

1) Fix the equipment on the equipment bracket with matching bolts, paying attention to the installation of flat spring pads;

2) Fix the equipment bracket to the monitoring pole about 3 meters away with matching bolts;

8、 Environmental protection measures

1. Waste disposal: Materials that are not suitable for filling should be promptly stacked neatly or transported to designated locations;

2. Construction wastewater shall be discharged into the sewer in a timely manner and shall not pollute natural water sources. The construction site should prevent and control noise pollution, and construction vehicles should not honk;

3. Prevent the excavated soil from being washed away or overflowing by rainwater, which can easily generate secondary dust in dry weather. The transportation crossing near the excavator needs to be cleaned in a timely manner.
