1. It is a kind of high-molecular polymer as the main raw material, adding certain anti-ultraviolet and anti-aging additives. After uniaxial stretching, the original distributed scattered chain molecules are aligned and linearly, and extruded. The sheet is then punched into a regular hole mesh and then longitudinally stretched into a high strength geotextile material. In this process, the polymer is oriented in a linear state and a long elliptical network-like monolithic structure with uniform distribution and high joint strength is formed. This structure has a very high tensile strength and tensile modulus, tensile strength of 100-200Mpa, close to the level of low carbon steel, much better than traditional or existing reinforced materials, especially the company The product has a high international level (extension of 2% - 5%) tensile strength and tensile modulus. The chain system that provides the ideal force for bearing and diffusion. The product has high tensile strength (>150Mpa) and is suitable for various soils. It is a widely used reinforcement material. One-way geogrid use:
One-way geogrid 1. One-way geogrid is used to reinforce weak foundation: geogrid can rapidly increase the bearing capacity of the foundation, control the development of settlement, and the lateral action of the road base can effectively distribute the load to a wider extent. On the base layer, thereby reducing the thickness of the base layer, reducing the construction cost, shortening the construction period and prolonging 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 needed. 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 and reduce the cost by 20-50%.
4. One-way 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 is permeable, can slow the impact of the waves, prolong the life of the dam, and save Manpower and material resources, 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. The low-temperature geogrid of Lianyi Company has been subjected to repeated hot and cold cycles at -45Â°C---50Â°C for 200 times. All performance indexes have met the requirements, and it has passed the test of Qinghai-Tibet Railway. It is suitable for less frozen soil in the north. Unfavourable geology of rich frozen soil and high ice content frozen soil.
