Chengdu geocell, Sichuan

  Chengdu Jinwen Yijia Building Materials Technology Co
, Ltd
is mainly engaged in geocell products, which have light material, wear resistance, stable chemical properties, light and oxygen aging resistance, acid and alkali resistance, high lateral restriction and anti-skid, anti deformation, and effectively enhance the bearing capacity of subgrade and disperse load
Widely used in highway and railway subgrade stabilization; Dike and shallow river regulation; Slope protection, mixed retaining wall and other works Geocell is a three-dimensional mesh cell structure formed by REINFORCED HDPE sheet material and high-strength welding
It is generally made by ultrasonic needle welding
Due to engineering needs, some holes are punched on the diaphragm Engineering application of geocell 1
When dealing with the semi filled and semi excavated subgrade and building the embankment on the slope with the natural gradient of the ground steeper than 1:5, steps shall be excavated at the embankment base, and the step width shall not be less than 1m
When the highway is built or reconstructed by stages, steps shall be excavated at the junction of the filling slope of the old and new subgrade
The step width of high-grade highway is generally 2m
Geocell shall be laid on the horizontal plane of each step, and the reinforcement effect of the elevation side limit of the geocell itself shall be used, Better solve the problem of uneven settlement
2
Subgrade in windy sand area Subgrade in windy sand area shall be mainly low embankment, and the filling height is generally not less than 0
3m Due to the professional requirements of Low Subgrade and heavy bearing capacity for Subgrade Construction in windy and sandy areas, the use of geocell can limit the loose filler and ensure that the subgrade has high stiffness and strength within a limited height to bear the load stress of large vehicles
3
Geocell can better realize the purpose of reinforcement of abutment back subgrade filling
Enough friction can be generated between geocell and filler to effectively reduce the uneven settlement between subgrade and structure, and finally effectively alleviate & ldquo; Abutment jump & rdquo; The early impact damage of the disease on the bridge deck
4
Subgrade in permafrost area when building filling subgrade in permafrost area, the minimum filling height shall be reached to prevent slurry boiling or the upper limit of frozen layer from falling, resulting in excessive settlement of embankment
The unique elevation reinforcement effect of geocell and the effective implementation of the overall lateral limit can ensure the minimum filling height in some special sections to the greatest extent, and make the filling have high-quality strength and stiffness
5
Loess collapsible subgrade treatment for expressways and first-class highways passing through collapsible loess and loess sections with good compressibility, or when the allowable bearing capacity of the foundation of high embankment is lower than the pressure of vehicle cooperative load and embankment self weight, the subgrade should also be treated according to the bearing capacity requirements
At this time, the superiority of geocell is undoubtedly revealed
6
Saline soil is used for saline soil and expansive soil
The expressway built with expansive soil, class I highway, shoulder and slope are reinforced
The facade reinforcement effect of the cell is the best of all reinforcement materials, and it has excellent corrosion resistance, which can fully meet the requirements of building high-grade highway in saline soil and expansive soil
