Product Description

Product Description

Geogrid is a three-dimensional mesh cell structure formed by high-strength welding of reinforced HDPE sheet material. Generally made by ultrasonic needle welding. Due to engineering needs, some holes are drilled on the membrane.
 

Characteristics of Geogrid

1. It can stretch and contract freely, and can be transported and stacked. During construction, it can be tensioned into a mesh and filled with loose materials such as soil, gravel, and concrete, forming a structure with strong lateral constraints and high stiffness.

2. Lightweight material, wear-resistant, chemically stable, resistant to light oxygen aging, acid and alkali, suitable for different soil and desert soil conditions.

3. High lateral restriction and anti slip, anti deformation, effectively enhancing the bearing capacity of the roadbed, and dispersing load.

4. Changing the geometric dimensions such as the height and welding distance of the geotechnical cell can meet different engineering needs.

5. Flexible expansion and contraction, small transportation volume, convenient connection, and fast construction speed. That is to say, once the load acts on the roadbed, a wedge-shaped active area will be formed below the load, which in turn compresses through the transition area, causing the passive area to bulge. That is to say, the bearing capacity of the foundation is determined by the shear force along the sliding line and the forces in the active, transitional, and passive areas of movement. Not only can the true process of the above principles be clearly experienced on sand bases, but also on soft foundation highways, this type of model can be found, but its formation rate is slower than that on sand. Even better roadbed materials cannot avoid lateral movement. Generally, the roadbed of a highway is several meters above the ground, and it is not easy to absorb water and frost, but long-term settlement still exists. Upon investigation, rainwater infiltration, material loss, and base subsidence are some of the reasons. The lateral displacement of materials towards both sides of the roadbed section under the long-term rolling and vibration force of wheel loads on the roadbed and pavement cannot be denied as another very important reason.

There is no need to elaborate on the conventional methods for treating roadbeds in engineering. The purpose is to improve the shear and friction resistance of foundation materials, reduce or delay their ability to move under load pressure or vibration. Therefore, there are inevitably many strict limitations on material requirements in engineering. If the required materials cannot be obtained nearby, they need to be purchased externally, The cost of purchasing materials and transportation accounts for a significant portion of the entire project cost. By using a geotechnical cell, materials can be obtained on-site or nearby, and even materials that cannot be used under normal circumstances can be used, greatly reducing material procurement and transportation costs.

application area
 

1. Processing half filled and half excavated roadbeds
When constructing embankments on slopes with a natural slope steeper than 1:5 on the ground, steps should be excavated at the base of the embankment, and the width of the steps should not be less than 1 meter. When constructing or renovating highways in stages, steps should be excavated at the junction of the filling slopes of the new and old embankments. The width of the steps on high-grade highways is generally 2 meters. Geogrids should be laid on the horizontal surface of each level of the steps, utilizing the lateral reinforcement effect of the facade of the geogrids themselves, Better solve the problem of uneven settlement.
2. Roadbed in windy and sandy areas
The roadbed in windy and sandy areas should be mainly composed of low embankments, and the filling height is generally not less than 0.3M. Due to the professional requirements of low embankments and heavy bearing capacity in the construction of embankments in windy and sandy areas, the use of geogrids can have a lateral confinement effect on loose fillers, ensuring that the roadbed has high stiffness and strength within a limited height to withstand the load stress of large vehicles.

 

3. Reinforcement of fill soil on the back of the embankment
The use of geogrids can better achieve the purpose of reinforcing the back of the bridge. The geogrids can generate sufficient friction between the geogrids and the filling material, effectively reducing the uneven settlement between the roadbed and the structure, and ultimately effectively alleviating the early impact damage of "bridge abutment jumping" disease on the bridge deck.

4. Roadbeds in permafrost regions
When constructing fill embankments in permafrost areas, the minimum fill height should be reached to prevent excessive settlement of the embankment due to frost heave or a decrease in the upper limit of the frozen layer. The unique facade reinforcement effect and effective implementation of overall lateral confinement of geogrid chambers can ensure the minimum filling height in certain special sections to the greatest extent, and make the filling have high-quality strength and stiffness.

5. Treatment of Loess Collapse Roadbed
When expressways and first-class highway pass through collapsible loess and loess sections with good compressibility, or when the allowable bearing capacity of the foundation of high embankments is lower than the pressure of the vehicle load and the self weight of the embankment, the subgrade should also be treated according to the requirements of the bearing capacity. At this time, the superiority of the geotechnical cells will undoubtedly appear.

6. Saline soil and expansive soil
The expressway, first-class highway, shoulder and side slope constructed with saline soil and expansive soil all adopt reinforcement measures. The facade reinforcement effect of the cell is the most excellent one of all reinforcement materials, and it has excellent corrosion resistance, which can fully meet the requirements of building highways in saline soil and expansive soil.
