Unidirectional stretched geogrid is a kind of high-strength geotechnical material made of high molecular polymer as the main raw material, adding certain anti-ultraviolet and anti-aging additives. After one-way stretching, the original scattered chain molecules are reoriented and arranged in a linear state, extruded into a thin plate, then punched into a regular orifice net, and then stretched longitudinally. In this process, the polymer forms a directional linear state and forms a long elliptical mesh integral structure with uniform distribution and high node strength. It has the following uses: 1. Unidirectional geogrid is used to reinforce weak foundations: geogrid can rapidly increase the bearing capacity of the foundation, control the development of settlement capacity, and the lateral effect on the road base can effectively distribute the load to the wider base layer, so as to reduce the thickness of the base layer, reduce the engineering cost, shorten the construction period, and prolong the service life. 2. Unidirectional geogrid is used to reinforce asphalt or cement pavement: geogrid is laid at the bottom of asphalt or cement paving, which can reduce the depth of the rut, prolong the anti-fatigue life of the pavement, and also reduce the thickness of asphalt or cement pavement to save costs. 3. Unidirectional geogrid is used to reinforce embankments Gapo and retaining walls: traditional embankments, especially high embankments, often need to be overfilled and the shoulder edge is not easy to compact, resulting in later slope rain inundation, collapse instability, and the need to use a slower slope, cover a large area, retaining walls have the same problem, the use of geogrid for the embankment Slope or retaining wall reinforcement can reduce the footprint by one-half area, extend the service life, and reduce the cost by 2050. 4. Unidirectional geogrid is used to reinforce river seawall: it can be used as a stone cage, and then used in conjunction with the grille to prevent the dam from collapsing by seawater. The stone cage has permeability, can slow down the impact of waves, prolong the life of the dam, save manpower and material resources, and shorten the construction period. 5. Unidirectional geogrid is used to treat landfills: geogrid is combined with other geosynthetic materials to treat landfills, which can effectively solve the problems of uneven foundation settlement, derivative gas emissions, etc., and can improve the storage capacity of the landfill to the limit. 6. Special purpose of unidirectional geogrid: low temperature resistance. After 200 cycles of repeated hot and cold cycles from 45 to 50, all performance indicators meet the requirements and have passed the test of the Qinghai-Tibet Railway. It is suitable for poor geology of less cryosphere, rich cryosphere, and high ice content permafrost in the north.
