Description

Assembled roadbed drainage side ditch Technical Field The utility model relates to the field of roadbed drainage, and particularly discloses an assembled roadbed drainage side ditch. Background The side ditch is a longitudinal artificial ditch arranged at the outer side of the road shoulder of the excavated roadbed and the outer side of the foundation foot of the low-fill roadbed, is used for collecting ground water of the road surface, removing slope water of the slope above the road intercepted by the roadbed, rapidly collecting and introducing the slope water into a smooth drainage channel, and discharging the slope water to the lower part of the road through bridges and culverts; Along with the strong construction of highway engineering in China, the improvement of engineering quality, the reduction of labor cost and the acceleration of construction speed become necessary trends, and the prefabricated technology is an effective method for solving the problems, the roadbed drainage adopts a drain gutter concrete cast-in-situ mode at present, the required labor force is more, the construction period is long, the quality is relatively poor, and a plurality of drain gutters have the defects of deformation, breakage and the like after operation for several years, so that the maintenance cost is high; The prior assembled drainage gutter adopts a modularized assembling mode, and is not provided with a buffer structure, so that the assembled drainage gutter is easy to deform, has poor safety and has short service life.
