Unidirectional plastic geogrid

Unidirectional plastic geogrids refer to high density polyethylene (HDPE) as raw materials, by plasticizing extrusion plate, punching, heating, stretching, extrusion press, thin plate and then punching regular hole mesh, and then longitudinal tensile geogrids. Generally used for laying in soil, through the mesh and soil between the interlocking and interlocking action, to form a high. The effective stress transfer mechanism can make the local load spread to the large area of soil quickly and effectively, so as to reduce the local failure stress and improve the service life of the project.

Purpose of unidirectional plastic geogrids:

★ Unidirectional plastic geogrid used to strengthen weak foundation: geogrid can rapidly improve the bearing capacity of the foundation, control the development of settlement, the lateral limiting effect of the road base can effectively distribute the load to a wider base, so as to reduce the thickness of the base, reduce the cost of the project, shorten the construction period, extend the service life.

★ Unidirectional plastic geogles for reinforced asphalt or cement pavement: geogles laid at the bottom of asphalt or cement pavement can reduce the depth of ruts, prolong the fatigue life of the pavement, but also can reduce the thickness of asphalt or cement pavement, to save cost.

★ Unidirectional plastic geoglide is used to strengthen the slope and retaining wall of the road embankment: traditional embankment, especially high embankment filling often needs. Fill and shoulder edge is not easy to compacting, resulting in late slope rain infiltration, collapse instability phenomenon occurs, at the same time need to use a slower slope, covers an area of large, retaining wall also has the same problem, the use of geogrille on the embankment slope or retaining wall reinforcement can reduce two to one area, extend the service life, reduce the cost of 20-50%.

★ One-way plastic geoglids used to strengthen river seawall: can be made of stone cage, and then with the grid, prevent the dyke by seawater erosion caused by collapse, stone cage has permeability, can slow the wave impact, extend the dyke life, save manpower and material resources, shorten the period.

★ Unidirectional plastic geogrid used for landfill treatment: geogrid combined with other soil synthetic materials to treat the landfill, can effectively solve the uneven settlement of the foundation, derived gas emissions and other problems, improve the storage capacity of the landfill.

★ Special use of unidirectional plastic geogrids: low temperature resistance. The low temperature resistant geogrids of Liyi Company, after 200 cold and hot cycles at -45 ℃-- 50℃, all the performance indexes meet the requirements, and have passed the test of Qinghai-Tibet Railway, suitable for the poor geology of little frozen soil, rich frozen soil, high ice content frozen soil.以
