发明名称 Apparatus and method for inserting a fabric web into the ballast of a rail road track.
摘要 <p>A fabric insertion system for placing fabric (10) in the rock ballast roadbed (12) of an existing railroad track at a predetermined depth beneath the ties (14) of the track includes a car (16) for supporting a roll (18) of fabric which is to be inserted into the ballast. A fabrik insertion sled (20) is secured to the car in a position beneath the car and in the ballast at a predetermined depth beneath the ties. The sled receives fabric (10) from the roll (18) on the car and the fabric is diverted within the sled such that it emerges therefrom at the depth of the sled. Fabric is continuously inserted into the ballast as the car and sled are moved along the track.</p>
