The invention relates to an installing and position adjusting method for a pipe joint end steel shell, in particular to an installing and positioning adjusting method for performing planarity precise adjusting to install the pipe joint end steel shell in a high-precision mode through precise adjusting components. The installing and position adjusting method includes the following steps that after a bottom plate steel bar binding process of a pipe joint is finished, a bottom plate end steel shell is correspondingly installed; after the bottom plate end steel shell is installed, a web steel bar binding process and a top plate steel bar binding process of the pipe joint are sequentially performed; after pipe joint steel bar cage binding is finished, a web end steel shell and a top plate end steel shell are correspondingly installed on web steel bars and top plate steel bars; a steel bar cage is sent to a pouring platform, and the bottom plate end steel shell, the web end steel shell and the top plate end steel shell are connected to form the pipe joint end steel shell; an end die with the precise adjusting components is correspondingly installed on the pipe joint end steel shell, and planarity checking is performed on the pipe joint end steel shell through the precise adjusting components; a concrete pouring process is performed on the pipe joint end steel shell.
