Geocell of earthwork grid construction method
4, permafrost subgradeIn the construction of embankment in permafrost regions, should reach the minimum height of fill, to prevent the occurrence of frost or freezing layer caused by upper limit decreased, resulting in the occurrence of excessive settlement of embankment. The whole side reinforcing effect of geocell specific and effective implementation, to the maximum extent to ensure that the minimum height of fill in some special area, and the high strength and stiffness of soil.5, loess collapsibility roadbed treatmentFor the highway and the highway through the collapsible loess and loess compression lots better, or high embankment foundation and embankment load is lower than the vehicle to allow the weight bearing pressure, should also be in accordance with the requirements of the subgrade bearing capacity, then the geocell superiority will undoubtedly show the.6, saline soil, expansive soilThe saline soil, expansive soil and construction of the highway, a highway, the road shoulder and slope reinforcement measures are used, the reinforcement effect of geocell facade is a reinforcement material in all the best, and it has excellent corrosion resistance, can fully meet in saline soil, expansive soil has higher requirements for highway.
Engineering application of geocell1, deal with half fill roadbedOn the ground of natural slope in 1:5 acts on the slope of embankment, embankment should be dug in steps, step width not less than 1M when the stage of building or rebuilding highway widening, convergence of old and new subgrade embankment slope, excavation step should be of high grade highway, the step width is 2M, the laying of geocell in each layer step on a horizontal plane, using geocell own facade side limit reinforcement effect, the problem of uneven subsidence of a better solution.2, sandy area roadbedSandy area on the low embankment subgrade, filling height is generally not less than 0.3M. due to the Low Subgrade Construction of sandy area and heavy bearing professional requirements, the geocell can play on the loose packing lateral confinement effect, with high stiffness and strength in the limited height of subgrade protection, to load large vehicle stress.3, the back embankment fillThe geocell reinforced abutment can achieve the purpose of better, geocell and fillers can generate enough friction, effectively reduce the roadbed and structures between uneven settlement, can effectively alleviate the "final abutment jump" disease of the early impact damage of bridge deck.
What is geocellGeocell is a kind of three-dimensional grid lattice structure geocell, which is made of HDPE material, which is welded by high strength.What are the characteristics of geocell1, with flexible, transport may be collapsed, the construction can be a Lacheng mesh, fill soil, gravel, concrete and other loose material, which has the structure of strong lateral limit and rigid body.2, light material, wear resistance, chemical stability, light oxygen aging, acid and alkali resistance, suitable for different soil and desert soil conditions.3, the higher lateral restrictions and non slip, anti deformation, effectively enhance the bearing capacity of the subgrade and scattered load.4, to change the height of geocell, welding distance and other geometric dimensions to meet the needs of different projects.5, flexible and easy to transport small size, convenient connection, construction speed.
