Scope of application
It is mainly used for retaining walls, abutments, steep slope works, etc;
Retaining walls and abutments are load-bearing structures, which bear all external loads: active earth pressure, dynamic load on the upper part of the structure, temperature stress, etc. Under the long-term action of large tension and the repeated action of dynamic load, the molecular structure of the material will fatigue, its performance will decay, and the grid will be accelerated. To avoid open The structure has large deformation due to the creep of reinforced materials, so the high-density polymer ethylene （ HDPE ）Unidirectional plastics as raw materials Geogrid 。
* * Use of unidirectional plastic grille!
a、 Uniaxial tensile geogrid is very suitable for strengthening soft soil foundation: this geogrid produced by us can rapidly improve the bearing capacity of soft foundation, control the development of settlement, and the side limiting effect on the road base can distribute the load to the * * * wide subbase, thus reducing the thickness of the foundation layer, reducing the project cost, shortening the construction period, and extending the service life.
b、 One way geogrid for reinforcement asphalt or cement Pavement: Geogrid is laid at the bottom of asphalt or cement pavement, which can reduce the rut depth, extend the pavement life, and reduce the thickness of asphalt or cement pavement to save costs.
c、 One way geogrid is used to reinforce embankment slope and retaining wall: the filling of traditional embankment, especially high embankment, often requires overfilling and the edge of the shoulder is not easy to compact, which leads to rain attack on the slope in the later stage, and the phenomenon of collapse and instability occurs from time to time. At the same time, slow slope is required, which covers a large area, and the retaining wall also has the same problem, Using geogrid to reinforce embankment slope or retaining wall can reduce the occupied area by half, extend the service life and reduce the cost.
d、 One way geogrid is used to reinforce rivers and sea embankments: it can be made into gabions and used together with geogrids to prevent the dam from collapsing due to sea water scouring, slow down the impact of sea waves, extend the life of the dam, save manpower and material resources, and shorten the construction period.
e、 The one-way geogrid is used to treat the landfill site: the geogrid is used in combination with other geosynthetic materials to treat the landfill site, which can solve the problems of uneven settlement of the foundation, emissions of derived gases, and can greatly improve the storage capacity of the landfill site.
f、 Use of one-way geogrid: low temperature resistance. The low-temperature one-way geogrid produced by the company has met the requirements of various performance indicators after repeated cold and hot cycles of - 45 ℃ - 50 ℃ for 200 times, and has passed the test of Qinghai Tibet. It is applicable to the less ice frozen soil, ice rich frozen soil, and high ice content frozen soil geology in the north.
