射水法建造混凝土防渗墙技术,是利用射水法造墙机在砂质、软土地基上施工建造混凝土防渗墙,具有施工简便、工效高及相对造价较低等优点。福建省水科所1990年研制成功的射水法混凝土造墙机二代机已获实用新型专利。该项技术已在16项工程中应用,都取得了较好效果。其中有福建的闽江、九龙江、晋江、湖北长江黄石段、江西骆马湖南堤等6项水利工程堤防加固,同时在工民建基坑开挖支护中
Water jet method of construction of concrete cutoff wall technology is the use of water jet method wall construction machine in sandy, soft soil foundation construction of concrete cutoff walls, with the advantages of simple construction, high efficiency and relatively low cost. Water Institute of Fujian Province in 1990 successfully developed water-jet concrete wall-making machine second generation machine has been utility model patents. The technology has been applied in 16 projects, have achieved good results. Among them, there are 6 water conservancy projects such as Minjiang, Jiulongjiang, Jinjiang in Hubei, Huangshi in Hubei Province and Nandi in Luoma in Jiangxi Province. At the same time,
