7. Precautions for installing the River flow monitoring system

1. Installation environment

There are no huge rocks blocking the water in the test channel section, and there are no huge whirlpools, turbulent flow, etc.

The test channel section should be straight, stable and have concentrated water flow

The test channel section needs to be hardened and the measurement section should be regular.

The test channel section should be kept smooth to prevent floating objects from accumulating.

2. Installation height

Recommended installation height 3-4 meters

Attachment: Hydrological Monitoring Station Construction Manual

1. Principles of layout:

1. The land use situation within 1,000 meters of the monitoring point is relatively stable;

2. The horizontal plane around the monitoring point should ensure a capture 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 surrounding environment of the monitoring point is relatively stable, the location conditions must be long-term stable and sufficiently solid, and the safety and fire prevention measures must be guaranteed;

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

5. The monitoring point should have 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 pollution sources within 50 meters around the monitoring point;

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

9. The monitoring point should be selected in a place with sufficient light (the daytime light time should be kept for more than 6 hours) or there should be a stable and reliable AC220V power supply around the monitoring point.

2. Point confirmation

After the selection of the points is completed, the points will be marked on the plane map of the monitoring area. The plane map with the location marks of the monitoring points will be submitted to Party A for confirmation and signature.

3. Construction

1. Pre-buried monitoring pole cage

1) According to the actual geological conditions on site, the pre-buried pit for the monitoring pole foundation is constructed by manual labor and excavation. The size of the pre-buried pit is 100cm (length) * 100cm (width) * 100cm (depth). If over-excavation occurs, the abandoned soil shall not be used for on-site backfilling. Gravel or sand shall be used to backfill to the design value. The edge of the pre-buried pit shall be aligned with the due south and due north directions;

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

3) Depending on the season and local climate, air-dry for about 3 days until the cement foundation is completely solidified to complete the pre-embedding.

2. Equipment installation and monitoring pole erection

1) Fix the equipment on the equipment bracket with matching bolts, and pay attention to the installation of flat spring washers;

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

3) Install the solar panel on the solar panel bracket with matching bolts;

4) Install the radar water level sensor on the flange with matching fasteners and fix the flange to the bracket.

IV. Construction quality control requirements and safety precautions

1. The whole process of monitoring pole construction should be carried out in sequence, and the pole appearance should be straight, streamlined, smooth and vertical;

2. The solar panel is tilted 45° towards the south;

3. The anti-rust layer of the monitoring rod must not be damaged;

4. The cable connectors are firm and reliable, waterproof and insulated, and not easily exposed;

5. Pay attention to the safety of pedestrians and vehicles during hoisting;

6. When hoisting the monitoring pole, be sure to tie a rope to control the stability of the lifting object;

7. Warning signs should be set up during lifting.

V. Construction Quality Assurance Measures

1. The main materials required should comply with the design documents and current standard requirements, and must have a factory certificate and should be tested when necessary.

2. Construction is strictly controlled according to the requirements of the specifications. And process inspection is carried out. Only when the previous process is qualified can the next process be constructed.

3. Strengthen quality awareness, strictly organize construction according to the design, current construction specifications and rules, as well as the owner's special requirements and on-site instructions, implement excellence work throughout the entire construction production process, and ensure project quality.

4. Strengthen process quality control, strictly organize production according to the quality assurance system, formulate operation standards, process standards, and inspection standards for each process and each link, keep records of the implementation of process standards, ensure that each process is connected in an orderly manner and achieve traceability.

5. Strengthen project management, implement the technical responsibility system, formulate targeted special construction plans, and carry out technical briefings carefully.

6. During construction, ensure that each sub-project is of high quality standard and all are of qualified quality, and establish model projects to drive the implementation of the entire project.

VI. Measures to ensure construction period

1. Strengthen technical guidance, strict management, and effective organization and coordination.

2. Strengthen management, improve the internal economic responsibility system, give play to the role of economic levers, and fully mobilize the enthusiasm and consciousness of the construction team as the organizational and ideological guarantee to ensure the construction period.

3. Organize a team with rich experience and strong construction capabilities; the personnel and mechanical equipment are well-equipped and complete to ensure that the construction plan is completed every day.

4. Grasp the node targets in stages. To facilitate inspection, assessment and adjustment, under the control of the overall construction plan, prepare the left and right construction plan targets, emphasize the node progress, and effectively control the realization of the overall plan.

5. Strengthen the management of material procurement and supply, and ensure timely supply of materials to meet the needs of project construction.

6. Actively coordinate relationships and create a good construction environment. Organize construction according to procedures to effectively control various factors that affect progress.

7. Safety construction management measures

During the implementation process, strictly abide by the laws and regulations on safety, health and environmental hygiene. Safety devices, equipment and protective equipment and other effective measures should be taken to protect the life, health and safety of on-site construction and supervision personnel;

8. Environmental Protection Measures

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

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

3. Prevent the excavated soil from being washed away or overflowed by rainwater, as secondary dust is easily generated in dry weather. The transport crossings near the excavator need to be cleaned in time.
