The technological process of geogrid are :Buy geogrid→Geogrid ested in laboratory→Geogrid transportation to the scene assembly laid→ Laying geogrid is complete →Prepared mechanical equipment →Laying caps gravel→ Watering ,compaction→ Ceiling height and degree of compaction.
The construction technological process of geogrid is : Bearing layer under the testing and cleaning→ Laying geogrid→overlap,colligation,fixation→Paving the upper subgrade soil→Rolling→Test.
Geogrid connection generally adopt colligation , lap width should not be less than l0 cm . In order to make it meet the requirements of the stress , generally every 10 ~ 15cm due a colligation point ; Stress direction in this range should be two colligation point ,multilayer , laid on the lower onto an emperical geogrid laying should level off , can't fold ,tension as far as possible , and then insert the u-shaped nail fixed .
Geogrid reinforcement technology is widely used in highway engineering , sumsup , can be roughly divided into retaining structure and foundation reinforcement , vehicledumpping and pavement structure reinforcement from four aspects .
