Research on Key Construction Technologies for Farmland Water Conservancy Facilities in Comprehensive Land Consolidation Across the Entire Region
全域国土综合整治中农田水利设施施工关键技术研究

摘要

全域国土综合整治将农用地整理、生态修复、村庄建设与水资源配置纳入统一空间治理体系，农田水利设 施则是改善农业生产条件、稳定耕地质量和提升区域防灾能力的重要支撑。受田块高程差异、既有渠系衔接复杂、 土质不均、施工点位分散及农业生产时序约束影响，传统单项水利工程施工方法难以满足全域整治对系统性、生态 性和长期运行效能的要求。本文结合农田水利设施施工特点，从水土资源调查、灌排系统布局和工程界面协调入手， 重点研究田块整平、渠道衬砌、渠系建筑物、泵站及管道施工等关键技术，并构建涵盖材料、工序、检测、运行验 证与后期管护的全过程质量控制体系。研究认为，农田水利建设应以灌排系统完整性为核心，通过高程统筹、分区 施工、节点精控和生态衔接，减少输水损失与局部积水，提高设施对现代农业和极端天气的适应能力。

Abstract

Comprehensive land consolidation across the entire region incorporates agricultural land consolidation, ecological restoration, village construction, and water resource allocation into a unified spatial governance system. Farmland water conservancy facilities are an important support for improving agricultural production conditions, stabilizing cultivated land quality, and enhancing regional disaster prevention capacity. Affected by differences in field elevation, complex connections with existing canal systems, uneven soil conditions, scattered construction sites, and constraints imposed by the agricultural production schedule, traditional construction methods for single water conservancy projects can hardly meet the requirements of comprehensive land consolidation for systematic performance, ecological compatibility, and long-term operational effectiveness. Based on the construction characteristics of farmland water conservancy facilities, this paper starts from water and soil resource investigation, irrigation and drainage system layout, and engineering interface coordination, and focuses on key technologies such as field leveling, canal lining, canal system structures, pump stations, and pipeline construction. It also constructs a whole-process quality control system covering materials, procedures, testing, operational verification, and post-construction management and maintenance. The study suggests that farmland water conservancy construction should take the integrity of the irrigation and drainage system as the core, and reduce water conveyance loss and local waterlogging through elevation coordination, zoned construction, precise node control, and ecological connection, thereby improving the adaptability of facilities to modern agriculture and extreme weather.
