Scope

Scope: This document specifies the terms and definitions of the standard for mechanized construction of small anti-seepage channels, and irrigation systems in farmlands: small channels used for field irrigation in rural areas with smaller cross-sectional dimensions and flow rates generally below 1 cubic meter per second. In areas such as southern rice-growing regions and northern vegetable-growing bases, mechanized construction can efficiently build anti-seepage channels and improve irrigation water utilization rates. Horticulture and orchard irrigation: Horticultural planting areas such as orchards, vegetable gardens, and flower beds have high requirements for irrigation accuracy and water conservation. Mechanized construction of small anti-seepage channels can meet the needs of these areas for flexible channel layout and good anti-seepage performance, ensuring rational distribution of irrigation water and reducing water waste. Small irrigation districts and water facilities in hilly areas: Some small irrigation districts are difficult to access with large-scale construction equipment due to complex terrain and small scale. Mechanized construction of small anti-seepage channels, with its flexible and adaptable features, can complete channel construction and anti-seepage treatment in areas with complex terrain such as hilly regions, ensuring irrigation water delivery.
