通过对现有地下灌溉系统的分析，论述了田间地下土基透水管灌溉、排水兼用的可行性及机理分析。在对国内外暗管施工机进行分类归纳的基础上，研制出土基透水管现场成型机，可现场一次完成土基管的成型、固壁、防渗、镶嵌渗水条等工序，初步对样机进行了田间试验，验证其结构合理性、经济性、并对土壤的破坏成型机理进行了分析 Based on the analysis of the existing underground irrigation system, the feasibility and mechanism analysis of using the underground pipe for underground irrigation and drainage are discussed. On the basis of classification and classification of domestic and foreign concealed construction machines, an on-site foundation-penetrating tube field forming machine is developed, which can finish the forming, solid wall, seepage prevention and inlaying seepage strips of the earth-based pipe once on site, Field experiments were carried out to verify the rationality and economy of the structure and to analyze the mechanism of soil failure
