description The utility model discloses a road sewage well well head is prevented protection lock spiral -lock and is put, including confined installation shell, set up the inner rotary table in the installationshell, two protective case and the two sets of spring bolt mechanisms that respectively set up in correspond protective case in of fixed connection on installation shell outer wall, the inner of two protective case all towards inner rotary table's the centre of a circle and two protective case for inner rotary table radial symmetry, the equal and inner rotary table fixed connection of pull rod oftwo sets of spring bolt mechanisms. The utility model discloses be convenient for when contracting in, the installation of well lid that on the lower terminal surface of well lid was fixed in in the installation, the pull rod contracted in realizing in the time of the inner rotary table pivoted, after well lid safety was accomplished, the pull rod is overhanging inner wall to the well lid firmly under reset spring's effect
