Technical Requirements And Standard Process For The Laying Of Geogrids

Geogrid laying is also a technical work, geogrid laid we can be good use, but there is no good shop, we have to operate again, so not only waste manpower, material resources, etc., there will be a time to waste. The laying of geogrid can not be as simple as our fantasy, not only the laying of the action can be finished, in the laying of the time, there will be a lot of questions we need to pay attention to, the aftermath of the work is not less.

The pavement surface of the geogrid should be relatively smooth. After the pavement layer is checked and qualified, in order to prevent the longitudinal askew appearance, the white line or hanging line is drawn in the pavement layer according to the width first, then the pavement can start, and then the end of the grid is fixed with nails (8 nails per meter wide, and the uniform distance is fixed). When the geogrid is laid, it is necessary to straighten and smooth and close to the base surface. Every 2-2.5m, the geogrid is fixed on the foundation with nails. The geogrid is bound with plastic belt along the transverse joint.

Paving: take the roll length as the length of the laying section, cover the back of the length of the section to be paved, and then check the quality of the paving as a whole, and then build the next section. In order to ensure its integrity, the length of the lap is not less than 20cm and not less than 3 holes, and the lap planning should be tied tightly.

When the laying of a section of geogrid is finished, the 25-50kg sand bag is used to fix the pressfoot at the lap joint and the edge of the geogrid. In order to prevent the geogrid from being damaged, the surface of the basic foundation should be level off to prevent the consolidation of bulges such as gravel and block stones. After the geogrids are laid, the construction of sand filling bags at both ends should be carried out in time. When the sand filling bags at both ends is finished, the construction of medium coarse sand cushion layer should be implemented immediately. Prevent geogrids from being damaged by tidal scour.
