Product Details

Reinforced asphalt pavement PP/HDPE Uniaxial Geogrid

Product name; Uniaxial geogrid

Material; Polypropylene (PP) Polyethylene (HDPE)

Width; 1-4m

Application:

1. Unidirectional geogrid is used to make superior inclined foundations: geogrid can quickly decorate the bearing attainable of the foundation, manipulate the enchancment of settlement, and efficiently distribute the load on a wider sub base layer due to its lateral limiting influence on the avenue base layer, thereby reducing the thickness of the base layer, decreasing engineering costs, shortening the constructing period, and extending the service life.

2. Unidirectional geogrid is used for reinforced asphalt or cement pavement: geogrid is laid at the bottom of the asphalt or cement pavement layer, which can limit the depth of ruts, extend the fatigue existence of the pavement, and moreover limit the thickness of asphalt or cement pavement to retailer costs.

3. Unidirectional geogrid is used to toughen river and sea embankments: it can be made into a gabion and used in combination with the grid to end the dam from collapsing due to seawater erosion. The gabion has permeability, which can gradual down the affect of waves, prolong the existence of the dam, hold manpower and cloth resources, and shorten the constructing period.

4. Unidirectional geogrid is used to deal with landfill sites: geogrids blended with special geosynthetic resources can efficiently treatment troubles such as uneven contract of the foundation and emissions of derived gases, and maximize the storage functionality of landfill sites.

Construction methods:

When used for bolstered soil preserving walls, the improvement strategy is as follows:

1. Set up the foundation and bring together in accordance to the designed wall system. When the use of precast bolstered concrete panels, they are typically supported on the precast concrete groundwork with a thickness of 12-15cm. Its width shall no longer exceed 30 cm, thickness shall no longer be a great deal much less than 20 cm, and burial depth shall now no longer be a whole lot much less than 60 cm to prevent the have an impact on of foundation frost heave.

2. Smooth the wall foundation, excavate and stage in accordance to the design requirements. Soft soil needs to be compacted or replaced, and compacted to the required density, which ought to barely exceed the fluctuate of the wall.
