摘要

The unit has two rails coupled by rail attachments (3) in predefined distances on an under bulge of a track and forming cover plate chambers. A lower part (4) reaching up to a rail partition wall (11), is narrowly arranged on rail-lower embossments. An upper part is inserted between the lower part and a rail head, and an integral shoulder is arranged on sides of the lower part, where the sides are turned towards the rails to support the upper part. The lower part is prefabricated when the upper part is longer than the lower part. An independent claim is also included for a lawn track equipped with a chamber filling unit.
