Based on the mechanism of wall formation and on the application of the impervious wall with vibration sinking mould to the entering-sea channel for the Bing Hai hydraulic hinge in Huai River, the measures for the design and the construction quality control are dis.

According to Jiangxi Liaofang Reservoir Babao dike construction experience of constructing wall by water jetting and underground continuous wall,the article introduces the forming wall theory of constructing wall by water jetting in dike anti-seepage project,construction measures,and the problems in the construction.

As there are so many fuzzy factors as economic,life,packing,maintaining,structural dimension in the design of the light hollow wallboard molding machine(LHWMM),and there hasn t been an effective synthetic evaluation used to fulfill the design of these problems up to now,it is difficult to confirm the optimal scheme among many design solutions of the wheel box of LHWMM.

A brief introduction was made on the construction technology,parameter selection and treatment of special cases of high-pressure jet grouting cutoff wall formation.
