Technical Specifications for Sprinkler Irrigation Projects

I. Introduction

The Technical Specifications for Sprinkler Irrigation Projects are intended to standardize the design, construction and operation of sprinkler irrigation projects, to ensure the efficient operation of sprinkler irrigation systems and the rational use of water resources. This specification is applicable to sprinkler irrigation projects such as farmland, orchards, flowers, and lawns.

II. Terms and Definitions

1. Sprinkler irrigation system: refers to a water supply facility consisting of sprinkler heads, pipes, valves, filters, pump stations, etc.

2. Sprinkler head: a device for spraying water, including parameters such as sprinkler head type, spray angle, and spray distance.

3. Pipeline: a pipeline system for conveying water flow, including main pipes and branch pipes.

4. Valve: used to control the opening and closing of water flow in the sprinkler irrigation system.

5. Filter: used to filter impurities in the water flow and protect sprinkler heads and pipes.

6. Pump station: a facility used to provide the water flow pressure and flow required by the sprinkler irrigation system.

III. Design requirements

1. Design principles

The design of the sprinkler irrigation system should follow the principles of water conservation, high efficiency, economy, and reliability.

2. Design parameters

Determine the nozzle type, spray angle, spray distance, flow rate and other parameters according to the water demand of crops, soil type, climatic conditions and other factors.

3. Pipeline layout

The pipeline layout should be reasonable to reduce pipeline resistance and pressure loss. The main pipeline should be arranged along the terrain line, and the branch pipeline should be arranged at a 45-degree angle with the main pipeline.

4. Valve setting

The valve should be set at the branch point of the main pipeline and the branch pipeline to control the irrigation of different areas.

5. Filter selection

Select a suitable filter according to the water quality of the water source to ensure the normal operation of the nozzle and pipeline.

IV. Construction requirements

1. Construction preparation

Before construction, the site should be surveyed to determine the terrain, soil type and water source. At the same time, prepare the required materials and equipment.

2. Nozzle installation

According to the design requirements, select the appropriate nozzle type and install it on the ground or underground to ensure the stability of the nozzle and the correct direction of water spraying.

3. Pipeline laying

According to the design requirements, lay the main pipeline and branch pipeline to ensure the slope of the pipeline and the firmness of the connection.

4. Valve installation

Install valves at the branch points of the main pipeline and branch pipeline to ensure flexible opening and closing of the valves.

5. Filter installation

Install filters in the pipeline according to design requirements, and clean and replace filters regularly.

6. Pump station construction

Build pump stations according to design requirements, install pumps and control equipment to ensure stable and reliable water supply.

V. Operation management

1. System inspection

Regularly check the operation of facilities such as sprinklers, pipes, valves, filters, etc., and promptly detect and handle faults.

2. Water resource management

Reasonably arrange irrigation time and water volume, and irrigate according to the water demand and growth stage of crops.

3. Water quality management

Regularly test the water quality of the water source to ensure that the water quality meets the irrigation requirements and avoid blockage of sprinklers and pipes.

4. Maintenance and maintenance

Regularly clean sprinklers, filters and pipes, check the operation of valves and pump stations, and promptly repair and replace damaged facilities.

VI. Safety and Environmental Protection

1. Safety Measures

During the construction and operation process, strictly abide by the safety operating procedures to ensure the personal safety of construction workers and users.

2. Environmental Protection

Rationally use water resources to reduce water waste. At the same time, select environmentally friendly materials and equipment to reduce pollution to the environment.

VII. Acceptance and Evaluation

1. Construction Acceptance

According to the design requirements and specification requirements, the sprinkler irrigation project is inspected and accepted to ensure that the project quality meets the requirements.

2. Operation Evaluation

Regularly evaluate the operation of the sprinkler irrigation system, analyze the water-saving effect and economic benefits of the system, and put forward improvement suggestions.
