Geogrid use

The uniaxially stretched geogrid is a kind of high-molecular polymer as the main raw material, and a certain anti-ultraviolet and anti-aging additive is added. After uniaxial stretching, the original distributed scattered chain molecules are rearranged in a linear state. High-strength geotechnical material which is extruded into a thin plate and then punched into a regular hole net and then longitudinally stretched. In this process, the polymer is oriented in a linear state and forms a long elliptical network-like integral structure with uniform distribution and high joint strength. 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. A chain system that provides the ideal force to bear and spread the soil. 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 is used to reinforce weak foundation: geogrid can rapidly increase 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 reduces the construction cost, shortens the construction period and prolongs the service life.

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 costs.

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 in the later slopes and collapse instability. The phenomenon 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 of one-half. Extend the service life and reduce the cost by 20-50%.

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 has permeability, which can slow the impact of the waves, prolong the life of the dam, and save manpower and material resources. , shorten the construction period.

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 maximize landfill. Field storage capacity.

Special use of unidirectional geogrid: low temperature resistance. The low-temperature geogrid of Lianyi Company has been subjected to repeated hot and cold cycles at -45°C---50°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 frozen tundra and high ice content frozen soil.

We also produce kinds of biaxial geogrid,such as fiberglass geogrid,polyester geogrid,pp biaxial geogrid,etc.
