Abstract
A method and a working machine (1) for the laying of wires (2) and/or infrastructures, wherein the steps of excavation (S) to execute an excavation (S) having a depth and width in accordance with the type of wire (2), of laying the wire (2) inside said excavation (S) and filling up said excavation (S) are executed without interruptions, through the use of just one working machine (1). The machine comprises a milling tool (12) to excavate a bench consolidating device (8), laying device (6) including a feeding duct (19), and filling device (7) including a tank (23) and injector device (24) to inject a semifluid material, for example concrete, into the bench. The injector device has a height control device (32) to control the level of the material to the bench
Claims7
A working machine for laying wires, the machine comprising:
- a supporting frame which can be connected to drive means suitable to move said frame along a predefined length of an excavation,
- excavation means suitable to execute said excavation,
- laying means having a feeding duct to lay wire inside said excavation,
- filling up means to fill up said excavation;
- and
- consolidation means of said excavation, which are located in an intermediate position between said excavation means and said laving means in order to consolidate the just executed excavation;
- wherein the excavation means, the laying means and the filling up means are all supported by said frame, and wherein an excavation width of the excavation is substantially comprised between 5 and 7 cm and a working depth of the excavation is substantially variable between 25 and 50 cm;
- and said feeding duct comprising a closing wall which can be disengaged from the duct in order to allow inspection of the duct.
