The invention belongs to the technical field of railway safety construction, and provides an installation method of railway concrete protection fences in order to solve the technical problems that subsequent parts cannot be installed accurately, a lot of locating brackets are required in the installation process and the construction costs are increased due to the inaccurate installation of railway concrete protection fence columns. The installation method specifically comprises the following construction steps: flattening of subgrade slope toe field-paying off and leveling-counting of the number of different types of columns-excavation of a foundation pit-primary pouring of concrete-placement of the columns-locating of the columns-placement of a mud sill-secondary pouring of concrete-installation of fence pieces, a head sill and column caps-tightening of the column caps-filling of bolts and concrete-treatment of ground clearances-installation of a top anti-throwing mesh and a bottom densification mesh. According to the installation method, the mud sill is installed firstly after adjusting the columns, and then the secondary pouring of concrete is performed, so as to solve the problem of inaccurate column locating; the construction efficiency is improved, the construction quality is ensured, and a lot of locating brackets are saved, so as to reduce the construction costs.
