China Professional Manufacture Pp Slope Protection Retaining Wall Geogrid Uniaxial Plastic Geogrid
Uniaxial Plastic Geogrid Introduction
The unidirectional geogrid is a kind of high molecular polymer as the main raw material, adding certain anti-ultraviolet, anti-aging additives, after unidirectional stretching, the originally distributed chain-shaped molecules are re-orientated and arranged in a linear state. It is a high-strength geotechnical material that is pressed into a thin plate and punched with regular meshes, and then stretched longitudinally. . In this process, the polymer becomes a directional linear state and forms an oblong network integral structure with uniform distribution and high node strength.

Uniaxial Plastic Geogrid Feature
With high compressive strength, low stress relaxation, and integration into various natural environmental soil layers, it can completely achieve the application of high and large retaining walls in expressways.
It can reasonably improve the interlocking of the reinforcing rib installation surface, the effect of tooth occlusion, the huge level of improvement of the bearing capacity of the roadbed, the reasonable side offset of the tube bundle sand, and the improvement of the firmness of the roadbed.
Compared with traditional grids, it has the characteristics of high compressive strength, strong load-bearing capacity, corrosion resistance, embrittlement resistance, high friction resistance, well-proportioned holes, convenient construction, and long service life.
It is more integrated into the seabed work and the reinforcement of the river bank structure, which solves the bottleneck problems of low compressive strength, poor corrosion resistance, and short application cycle caused by long-term sea surface abrasion caused by other raw materials made of gabion cages.
It can reasonably prevent construction damage caused by being crushed and destroyed by the machine during the whole process of construction
Plastic Uniaxial Geogrid Fuction
1. One-way geogrid is used to reinforce weak foundations: Geogrids can quickly increase the bearing capacity of foundations, control the development of settlement, and confine the road base to effectively distribute the load to a wider base. Thereby reducing the thickness of the base layer, lowering the project cost, shortening the construction period and prolonging the service life.
2. One-way geogrid is used to reinforce asphalt or cement pavement: the geogrid is laid on the bottom of asphalt or cement pavement, which can reduce rutting depth, prolong the fatigue life of the pavement, and reduce the thickness of asphalt or cement pavement to save cost.
3. The unidirectional geogrid is used to reinforce the embankment dam and the retaining wall: the traditional embankment, especially the high embankment, often needs to be overfilled and the edge of the shoulder is not easy to compact, which will cause the slope to be flooded and collapsed in the later stage. The phenomenon of instability occurs from time to time, and at the same time, a gentle slope is required, which covers a large area, and the retaining wall has the same problem. The use of geogrids to reinforce the embankment slope or retaining wall can reduce the area occupied by half. Area, extend the service life, reduce the cost by 20-50%.
4. Unidirectional geogrid is used to reinforce rivers and sea dikes: it can be made into stone cages, and then used together with grids to prevent the dam from being washed by seawater and cause collapse. The stone cages are permeable, can slow down the impact of 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 garbage landfills: the combination of geogrid and other soil composite materials to treat garbage landfills can effectively solve the problems of uneven foundation settlement and derived gas emissions, and can maximize The storage capacity of the landfill.
Uniaxial Plastic Geogrid Usage
Unidirectional stretching geogrid is used to reinforce the embankment dam slope and retaining wall: the traditional embankment, especially the high embankment, often needs to be overfilled and the edge of the shoulder is not easy to compact, which leads to the rainwater infiltration and collapse of the slope in the later period. The phenomenon of instability occurs from time to time, and at the same time, a gentle slope is required, which covers a large area, and the retaining wall has the same problem. The use of geogrids to reinforce the embankment slope or retaining wall can reduce the area occupied by half. Area, extend the service life, reduce the cost by 20-50%; unidirectional stretching geogrid can also be used to strengthen rivers and sea dikes: it can be made into a stone cage, and then used with the grid to prevent the dike from being washed by sea water and cause collapse. The cage has permeability, can slow down the impact of waves, extend the life of the dam, save manpower and material resources, and shorten the construction period.
Construction method of one-way geogrid:
Excavate the foundation bed, set up a sand cushion (the height difference is not more than 10cm), roll it into a platform, and lay a grid. The longitudinal axis should be consistent with the main force direction, and the longitudinal overlap should be 15-20cm, the lateral 10cm, and the overlap Bind it with plastic tape, and fix it on the ground with U-shaped nails every 1.5-2m on the laid grid. The laid geogrid should be backfilled with earth material in time. The number of layers of the laid geogrid depends on the technical requirements. The construction process requirements of the geogrid: the paving surface of the geogrid should be relatively flat. After the paving layer has passed the experience, in order to prevent the longitudinal skew phenomenon, first draw a white line or hanging line on the paving layer according to the width. You can start paving, and then use iron nails to fix the ends of the grille (8 nails per meter width, fixed at a uniform distance). After fixing the ends of the grille, use a paving machine to slowly pull the grille forward, and manually tighten and straighten it every 10 meters long until one roll of grille is finished, and then another roll is laid. The operation is the same as before. After laying a roll, use a 6T-10T roller from the starting point to roll it in the forward direction. (If paving on the middle layer and leveling layer, it is better to use a steel roller roller; if the grating is directly laid on the concrete pavement, it is better to use a rubber roller roller.) For the section length, after the section length of the grid should be paved, check the paving quality as a whole, and then pave the next section. When laying the next section, the grid and the grid can be overlapped with a length of 10-15CM, and fixed with iron nails or wooden wedges, and then continue to pave the second section in the forward direction. By analogy, the operation requirements are the same as before.
