Plastic tensile geogrid - when laying the plastic geogrid, the filling material shall be selected according to the requirements of engineering design. According to the previous engineering experience, geogrids are suitable for most soils, and can be used as filling materials except frozen soil, swamp soil, domestic waste, chalk soil and diatomite. However, gravel soil and sand soil have stable mechanical properties and little affected by water content, so they should be preferred. The particle size of filler shall not be greater than 15cm, and the grading of filler shall be controlled to ensure the compaction weight. When plastic geogrid is used, how to deal with its performance in soft soil foundation? This is a problem that Lianyi Engineering Plastics Co., Ltd. has been paying attention to. In the construction of plastic geogrid, it mainly includes three aspects:

1、 The foundation conditions of each project are different, and the selected materials have different specifications;

2、 Engineering geological environment along the line;

3、 Geogrid cushion in subgrade.

In the construction process of plastic geogrid, although it is not a complicated step, it also needs corresponding procedures to implement, which can be roughly divided into the following four steps.

(1) The determination of the scheme. (2) The principle of comprehensive foundation treatment with geogrid cushion house. (3) Performance and material requirements. (4) The construction procedure and key points of foundation treatment with geogrid cushion.

While controlling the price of geogrid, it is necessary to ensure that the subgrade soil should be filled in layers and meet the requirements of relevant specifications. In addition, it should be avoided that the truck directly rolls on the paved and tensioned grid. During the construction, the filling rate of embankment should be controlled and the observation of settlement and lateral displacement should be strengthened to prevent the embankment from instability.
