It can be applied in a large car park and terminal freight yard, etc. to strengthen the foundations of a permanent load; 3. It can be applied in rail, road slope's protection; 4. It can be applied to enhance the culvert |
Biaxial Plastic Geogrid Precautions
- The turning or braking of vehicles on the geotextile should be avoided as far as possible, especially when paving the asphalt surface course, any sharp turning or car killing sliding may bring up or damage the geotextile.
- Construction under rainy, humid or cold weather conditions will affect the bonding strength and overlay effect of the coating.
- Traffic must be closed during laying. Except for construction vehicles, other vehicles are allowed to pass through the geotextile only in case of emergency.
- If there is slippage of paver when paving hot mix asphalt mixture, a small amount of stone chips can be sprinkled on the surface of tack coat oil.
- Generally speaking, when we master the construction points of geotextile skillfully, we can make it play a greater economic benefit and make greater contribution to our urban construction.
Biaxial Plastic Geogrid Advantage
- The good air permeability and water permeability of geotextile are used to make the water flow through, thus effectively retaining the loss of sand.
- Geotextile has good water conductivity. It can form drainage channel inside soil and drain excess liquid and gas from soil structure.
- It can effectively diffuse, transfer or decompose the concentrated stress to prevent the soil from being damaged by external force.
- Prevent the upper and lower layers of sand and gravel, soil and concrete mixing.
- High water permeability - good water permeability can be maintained under the pressure of soil and water.
- Corrosion resistance - polypropylene or polyester fiber and other chemical fibers as raw materials, acid and alkali resistant, corrosion-free, moth free, antioxidant.
- Simple construction - light weight, convenient use and simple construction.
Construction technology requirements
The paving surface of geogrid should be relatively flat. After the acceptance of the paving layer, in order to prevent the longitudinal deflection, first draw a white line or hang a line on the paving layer according to the width, and then start paving. Then fix the end of the geogrid with iron nails (8 nails per meter wide, fixed at an even distance).
After fixing the end of the grid, use the paver to slowly pull the grid forward, and manually tighten and straighten the grid every 10 meters long until one roll of grid is paved, and then lay the next roll. The operation is the same as before.
After a roll is paved, it can be rolled by 6t-10t roller from the starting point to the forward direction. (if it is paved on the middle surface course and the leveling layer, it is better to use the steel roller roller; if the grid is directly laid on the concrete pavement, the rubber roller is suitable.)
Joint paving: take the roll length as the unit of laying section length. After the grid should be laid within the section length, the overall paving quality shall be checked once again, and then the next section shall be paved. When the next section is paved, the overlapping length of the grid and the grid can be 10-15cm, and the second section can be paved in the forward direction after it is fixed with iron nails or wooden wedges. By analogy, the operation requirements are the same as before
