Infiltracinis - žolinis griovys
Abstract
Invention belongs to the group of automobile road devices, which are equipped and exploited in the roads ground beds and used for taking off surface water. This seepage-grassy trench for collection of road surface runoff should be equipped when laying a new road, or during the reconstruction of existing one. The trench serves for the road surface runoff collection, taking off, stabilization of roadside soil, roadside planting and soil recuperation. Seepage-grassy trench for collection of road surface runoff is formed from: ground base, chamfer-shaped bottom of the trench, filtrating sand layer, loam layer, mixed with 10 percent (of loam volume) of 3-5 mm fraction natural zeolite (klinoptilolite) and trench slopes, cropped with herbaceous species - ryegrass (Lolium perenne L.) and fescue grass (Festuca pratensis Huds.).
