Introduction of Geogrid Retaining Wall

At present, the design theory and construction technology of geogrid retaining wall are becoming more and more mature. It has been widely used in civil engineering because of its low cost and good performance.

The reinforced earth geogrid retaining wall shows its unique advantages in cost and structure in the valley area of some mountains and heavy hills and the special slope with steep cross slope.

In this article, the types and characteristics of geogrid reinforced retaining wall are briefly introduced, It can be used for reference in the construction of similar geogrid reinforced earth retaining wall.

1.Types and Characteristics of Geogrid Retainning Wall:

1.1 type of reinforced earth retaining wall:

Geogrid reinforced earth retaining wall can be divided into two types according to the presence or absence of the wall panel: the one with panel reinforced earth retaining wall and the one without panel reinforced earth retaining wall.

According to the panel form, the panel reinforced earth retaining wall can be divided into: the whole panel reinforced earth retaining wall and the assembled panel reinforced earth retaining wall.

At present, the reinforced earth retaining wall with assembled panel is widely used, and the modules of assembled panel usually have different forms such as rectangle, hexagon, cross, l and groove.

The panel module design can be flexibly prefabricated into various shapes according to the needs of the project environment, which can provide a good visual effect; color cement can also be used to increase the artistry of the wall.

The non panel ecology block retaining walls w geogrid is also known as the reverse wrapped or wrapped reinforced earth retaining wall. The wall is made of mesh bag fill and then reverse wrapped by the geogrid. Each layer of geogrid is connected by a special connecting rod to form a whole. The fill in the mesh bag has been mixed with grass seeds, shrub seeds, flower seeds, etc. suitable for local growth. After several months, the green ecological wall is formed. This not only protects the use safety of geogrid, but also beautifies the environment of retaining wall engineering.

1.2 characteristics of reinforced earth retaining wall:

1) Geogrid wall is a flexible structure. Compared with the traditional rigid structure, the retaining wall can better adapt to the deformation of the foundation, especially in the poor foundation can show its structural advantages.

In addition, it is reported that the reinforced earth retaining wall has better seismic resistance than the rigid retaining wall.

2) Geogrid reinforced earth retaining wall can save engineering investment, retaining wall can be made high and steep, can effectively save land and filling materials, and has economic advantages.

3) The reinforced earth retaining wall with face plate can be made into different shapes and structures according to different environments and in consideration of the requirements of aesthetics, which can be effectively integrated into the surrounding environment;

The non panel reinforced earth retaining wall and the slope are protected by greening, which has good social benefits for greening, beautifying the environment and restoring the natural ecology.

4) The construction of geogrid reinforced earth retaining wall is convenient and fast, which can shorten the construction period and ensure the construction quality.

5) The design and construction technology of geogrid reinforced earth retaining wall is becoming more and more mature. After the development in recent years, reinforced earth technology has been widely used in highway, railway, airport, port, water conservancy, municipal and ecological environmental protection engineering and other fields.

1.3 scheme selection of geogrid reinforced earth retaining wall:

When determining the scheme of geogrid reinforced earth retaining wall, it is necessary to combine the topography and geological conditions of retaining works.

Sufficient space is needed behind the retaining wall to obtain enough reinforced area to ensure the internal and external stability and overall stability of the reinforced earth retaining wall.

That is to say, geogrid reinforcement earth retaining wall is suitable for filling engineering, especially in the construction of highway engineering and railway engineering in mountainous and heavy hilly areas, the treatment of half excavation and half filling or the combination of filling and digging can play its unique role.
