The Effect Of Geogrid Used in Roadbed Ground Drainage
During the construction of the geogrid, especially when the roadbed is strengthened, the ditch should be surrounded by a curve where the longitudinal slope of the ditch should converge in the longitudinal light, and no accumulation of water or overflow is allowed inside the curve. The water is introduced into the natural hillside side trough entrance or bridge culvert, the drainage ditch mouth must be strong, the sewer should be provided, if necessary, or water jets or tanks.
The effect of water. The subgrade structure geogrid, or the box water jet must use the mortar masonry structure according to the terrain, the height of the water drops, and other geological conditions. The multi-step height level can be changed and the length ratio should be adapted to the original ground slope. The masonry base requires the setting of terminals and Internet bars. The embankment side slope jet channel structure, which can flow into the drainage, should provide a flat trickle channel, and the edge of the road and the opening enter the transition part. The water jet of the embankment slope should be connected to the flat trickle groove. The embankment slope is to avoid a high road through which the water can pass and provide a water retention shoulder. Part of the road curbs, drainage ditch, or interception provided with water holding tank openings to prevent the flow of water jets from the embankment far away from the embankment and the embankment height spray groove connection shall be provided with speaker openings. The curb shoulder must be arranged according to the local design. Shoulder should be properly strengthened in the roadside part of the roadside.
The geogrid of the roadbed and the drainage ditches out of the road must have a smooth interface with other drainage facilities. In order to prevent water infiltration and erosion, the drainage ditch should be closely seepage and increase. The unfavorable geological profile and soft soil seepage are suitable for cracks. The soil water blocking drainage ditch part and the ditch outlet with larger rock or larger ditch longitudinal slope should be strengthened Measures to prevent water seepage and erosion, ditch walls. When used for paving in a ditch with paving stones, it must have thin slices of rock, and each jigsaw piece of pebbles should use a flat surface with a solid opening; the joints with paving mortar stones and masonry mortar should be sufficient, and the main groove should be watertight; if the bottom of the groove is gypsum At that time, the stone bones should be lighted by the calender.
