The gutter cut aims to capture the waters poured over the platform and slope cutting and lead them along the highway, to the point of transition between cutting and filling, to enable the output side to the natural ground or a trench landfill, or, to a collector box culvert greide. The gutters should be located in all cuttings, being built on the fringes of shoulders, finishing convenient exit points (crossing points cut landfill or collection boxes).
The Gutter landfill aims to capture the water precipitated on the platform, to prevent erosion causing the edge of the shoulder and/or the slope of the landfill, leading them to the place of runoff insurance.
The gutter protection cuts aim to intercept the waters that flow the natural terrain upstream, preventing them from reaching the cut slope. The gutter protection will be built into all passages in which the court runoff from the adjacent land can reach the slope, compromising the stability of the body estradal. Should be located closely the crests of parallel cuts at a distance of 2.0 to 3.0 meters. The material resulting from the excavation must be placed between the trench and the crest of the cut and apiloado manually as indicated:
The gutter protection embankments are designed to intercept water seeping the land upstream, preventing them from reaching the foot of the slope of the landfill. Also, have the purpose of receiving the waters of the gutters and ditches cut, leading them to safety device to transpose watercourses.
When a highway is projected onto dual carriageway, ie, where the lanes are separated by a concave central site, it is necessary to drain it through superficially a device called the median ditch. (Fig. 68). This ditch aims to capture the water from the slopes and the very median and bring them along to be captured by collecting boxes of culverts greide.
