1. Point layout principles:

1. The land use conditions within 1,000 meters near the monitoring point are relatively stable;

2. The horizontal plane around the monitoring point should ensure a collection space of more than 270°. If the monitoring point is close to a building, the horizontal plane around the monitoring point should have a free space of more than 180°;

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

4. There is no strong electromagnetic interference or strong vibration 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 location of the monitoring point has smooth and convenient access and conditions to facilitate maintenance;

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

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

8. When the weather station is installed on a non-matching customized monitoring pole, the load-bearing capacity of the basic pole must be considered;

9. The monitoring point should try to choose a place with sufficient lighting (try to keep the light time above 6 hours during the day) or there should be a stable and reliable AC220V power supply around the monitoring point.

2. Point confirmation

After the selection of distribution points is completed, mark the points on the plan map of the monitoring area. Submit the floor plan with the location of the monitoring points to Party A for confirmation and signature.

3. Construction

1. Pre-embedded monitoring pole and ground cage

1) According to the actual geological conditions on site, the pre-buried pit for the monitoring pole foundation is constructed manually with an excavator. The size of the pre-embedded pit is 100cm (length)*100cm (width)*100cm (depth). If over-excavation occurs, spoil shall not be used to backfill on site, and gravel or sand shall be used to backfill to the design value. The edge of the pre-embedded pit should be aligned with the south and north directions;

2) Stand the embedded parts vertically in the pit with the threads facing up, and fill the pit with concrete (cement:sand=1:3) until it is slightly above the ground level;

3) According to the season and local climate environment, it will take about 3 days to dry until the cement foundation is completely solidified and then the pre-embedding is completed.

2. Equipment installation and monitoring pole erection

1) Use matching bolts to fix the equipment on the equipment bracket, paying attention to the installation of flat spring washers;

2) Use matching bolts to fix the equipment bracket to the monitoring pole about 3 meters away;

8. Environmental protection measures

1. Waste disposal: Materials that are not suitable for filling should be piled neatly or transported to designated places in a timely manner;

2. Construction wastewater shall be discharged to the sewer in a timely manner and shall not pollute natural water sources. Noise pollution must be prevented and controlled at construction sites, and construction vehicles must not sound their horns;

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