Method and device for establishing a guard rail structure, in which a number of posts (4), each being provided with a threaded anchor (9), are brought into the ground simultaneously with the help of a robot (7) arranged on a vehicle (1). Subsequently, the vehicle (1) is moved and a guard rail segment (13) is connected to said posts (4) with the help of a second robot (11) arranged on a vehicle (12). Therein, snap fittings (16 - 19) are employed between the guard rail segment and the posts. The ends (23) of said guard rail segments (13) are designed in such a way, that they can be mated on mounting. The guard rail segments (13) are provided with signalling members (25, 26) and with cables (27) extending to said members. Members (26) can show a "green wave". <IMAGE> |
