Since the early 1980s, China has started the application and research of synthetic materials such as geotextiles. Through its application in many projects, the advantages of this material and technology are increasingly recognized by the engineering community. Geosynthetics have functions such as filtration, drainage, isolation, reinforcement, seepage prevention, and protection. Among them, reinforcement functions (especially new types of geosynthetics) have been increasingly used in recent years, and their application fields have gradually expanded. However, the application of this technology in China is not yet widespread, and it is currently in the promotion stage, especially in large and medium-sized projects. Geogrid manufacturer system
It has been found that currently, geogrids are mainly used in highway, railway, and other projects, but also gradually used in hydraulic engineering such as flood control embankments, cofferdams, and inland port and wharf projects. According to the performance and characteristics of geogrids,
Its main uses in the project are:
(1) Foundation treatment. It can be used to strengthen weak foundations, rapidly improve foundation bearing capacity, and control foundation settlement and uneven settlement. Currently, it is mostly used in railway, highway, and other projects with relatively low requirements for foundation treatment.
(2) Reinforced soil retaining wall and revetment. In reinforced earth retaining walls, the tensile force of geogrids and the constraints on lateral displacement of soil particles will greatly increase the stability of the soil itself. Currently, it is mainly used for reinforcement of railway and highway slope retaining walls, river embankment revetment, and some high slope projects.
In recent years, more and more attention has been paid to the construction of flood control and bank protection projects, and the number of construction projects has increased, leading to the increasingly widespread application of geogrids in embankment projects. Especially in urban embankment projects, in order to reduce the floor area of the embankment project and increase valuable land resources, the slope protection of river embankments always tends to adopt a steeper slope. For embankment projects filled with earth and rock, when the filling materials cannot meet the stability requirements for slope protection, the use of reinforced soil not only can effectively meet the stability requirements for slope protection, but also can reduce the uneven settlement of the embankment body, with good engineering benefits.
