A construction method for precisely controlling a frozen soil curtain among pipes comprises the steps that when pipe joints are processed, manufactured and constructed, auxiliary freezing pipes inside a pipe-curtain blank pipe is directly welded onto a pipe joint of the pipe-curtain blank pipe according to the position and angle at which a pipe curtain is located; the pipe joints are successively pushed in by adopting a pipe pushing machine, and the pipe curtain is finally formed; a soil body improvement grouting pipe is installed; micro-expansion cement paste is used for backfilling; a full-automatic temperature monitoring system is established; a freezing system is debugged; all-dimensional frozen soil curtain temperature monitoring is carried out after freezing is started; all freezing pipes are closed and then thaw settlement grouting pipes are installed after a self-waterproof system is formed by virtue of the completion of tunnel overall excavation and support; the micro-expansion cement paste is used for backfilling after thaw settlement grouting is finished, and the construction is finished. The construction method for precisely controlling the frozen soil curtain adopts circulating normal-temperature water for manual heating and thawing, and at the same time, the tracking mode thaw settlement grouting is carried out, so that the influence of thawing settlement on surface deformation can be effectively reduced. The construction method is safe, reliable and practical.
