Analysis of the use of one-way plastic geogrid

1. One-way plastic Geogrid is used to reinforce weak foundation: geogrid can rapidly improve foundation bearing capacity, control the development of settlement, and the lateral action of the road base can effectively distribute the load to a wider subbase. , thereby reducing the thickness of the base layer, reducing the construction cost, shortening the construction period and extending the service life.

2. One-way geogrid is used for reinforced asphalt or cement pavement: geogrid is laid on the bottom of asphalt or cement pavement to reduce the depth of rutting, prolong the fatigue life of pavement, and reduce the thickness of asphalt or cement pavement to save cost.

3. One-way geogrid is used to reinforce the embankment and the retaining wall: the filling of traditional embankments, especially high embankments, often requires overfilling and the edges of the shoulders are not easily compacted, resulting in rain erosion and collapse of the later slopes. The phenomenon of instability occurs from time to time. At the same time, a gentle slope is required. The floor space is large and the retaining wall has the same problem. The use of geogrid to reinforce the embankment slope or retaining wall can reduce the area occupied by two parts. Area, extend the service life, reduce the cost by 20-50%.

4. One-way plastic geogrid is used to reinforce rivers and seawalls: it can be used as a stone cage, and then used together with the grille to prevent the dam from being collapsed by seawater. The stone cage has permeability, which can slow the impact of the waves and prolong the life of the dam. Save manpower and material resources and shorten the construction period.

5. One-way geogrid is used to treat landfills: Geogrid is used in combination with other soil synthetic materials to treat landfills, which can effectively solve problems such as uneven settlement of foundations and derivative gas emissions, and can maximize the problem. The storage capacity of the landfill.

6, the special purpose of one-way geogrid: low temperature resistance, after -45 ° C - 50 ° C repeated hot and cold cycle 200 times, all performance indicators meet the requirements, and has passed the test of the Qinghai-Tibet Railway, applicable to Less frozen soil in the north, rich frozen soil, and high-ice frozen soil.
