Retaining walls are structures that support roadbed fill or hillside soil and prevent fill or soil from deformation and instability. They often appear in highway construction.As time goes by, the dry stones in the gabion retaining wall of our Shunmai Company will be filled with soil, and the roots of the vegetation will penetrate deeply into the soil between the stones, forming a tightly combined flexible structure. Compared with the traditional mortar rubble and concrete protection, the structure has many advantages such as 'ecological nature', 'landscape nature' and low foundation requirements, and is more in line with today's new highway design concepts.
Gabion mesh is mechanically woven from low-carbon steel wires with high corrosion resistance, high strength and ductility or PVC-coated steel wires. The box-shaped structure made of this mesh is a gabion.The diameter of the mild steel wire used varies according to engineering design requirements according to ASTM and EN standards.Generally between 2.0-4.0mm, the tensile strength of the gabion mesh steel wire is not less than 38kg/m2, the weight of the metal coating is generally higher than 245g/m2, and the edge line diameter of the gabion mesh is generally larger than the diameter of the network cable.The length of the twisted part of the double wire shall not be less than 50mm to ensure that the metal coating and PVC coating of the twisted part of the steel wire are not damaged.
Production Process:
Raw material selection (wire rod) - cold drawing/galvanizing/plastic coating - machine weaving - manual shearing and assembly - product inspection - packaging and transportation - installation and maintenance
● Pre-construction preparation and survey
Before installing and constructing gabion nets for highway projects, it is first necessary to conduct a detailed survey of the construction area to understand factors such as topography, soil characteristics, and surrounding environment.Based on the survey results, formulate an appropriate construction plan and prepare corresponding construction equipment and materials.At the same time, the construction personnel will be trained to ensure that they are familiar with the installation requirements and operating procedures of gabion nets.
● Gabion net installation and processing
Install and process gabion nets according to construction drawings and actual site conditions.During the installation process, attention should be paid to controlling the spacing and heavy fragrance between meshes to ensure the stability and protective effect of the mesh.For specially shaped slopes or terrain, custom processing is required to meet design requirements.
● Filling and fixing methods
The filling material of the gabion net should be hard and regular-shaped stones, and should be carried out in accordance with the principle of layered filling.After each layer of filling is completed, use small stones or gravel to fill and tamp it to ensure tightness between the stones.At the same time, attention should be paid to controlling the filling speed and intensity during the filling process to avoid damage to the gabion net.
The fixing method can use iron wires or connectors to connect and fix the gabion net with the foundation or adjacent gabion nets.When fixing, make sure the connection is firm and stable, and can resist the influence of external factors.
● Slope treatment and greening
After completing the installation and filling of the gabion net, the slope needs to be treated and greened.This includes removing debris and loose soil from the slopes and performing necessary grading and compaction work.Then, green planting is carried out according to the design requirements to improve the stability of the slope and beautify the environment.
● Later maintenance and inspection
After the installation of highway engineering gabion nets is completed, subsequent maintenance and inspections during the running period are required.This includes checking the integrity of the gabions, the tightness of the connections, and the stability of the fillers.Any problems found must be dealt with and repaired in a timely manner, such as replacing damaged mesh, tightening loose connections, etc.
● Remove buildup and pollution
Over time, gabions may accumulate debris or become contaminated.Therefore, it is necessary to regularly remove the accumulation and contaminants on the gabion net to keep it clean and beautiful.At the same time, care should be taken to avoid using chemicals for cleaning that may cause corrosion or damage to the gabion mesh.
● Filling inspection and adjustment
Due to natural factors or human activities, the filling in the gabion mesh may be displaced or deformed.Therefore, it is necessary to regularly check the status and distribution of the filling and make necessary adjustments.This includes things like replacing lost stone, tidying up displaced stone and replacing damaged filling.
● Damage Prevention and Treatment
In order to prevent the gabion net from being damaged, corresponding preventive measures need to be taken.For example, set warning signs around the gabion net to prevent vehicles or people from colliding or damaging it.At the same time, we must pay close attention to early warning information about weather changes and natural disasters, and take timely response measures.
Damage problems that have occurred need to be dealt with and repaired in a timely manner.For minor damage, you can repair it yourself; for larger damage or problems that cannot be repaired by yourself, you need to contact a professional construction team for processing.
To sum up, the installation, construction and maintenance of highway engineering gabion nets is a comprehensive work.By doing a good job in pre-construction preparation and survey, installation and processing of gabion nets, filling and fixing methods, slope treatment and greening, and later maintenance and inspection, the stability and protection of gabion nets in highway projects can be ensured. The effect is to improve the safety and aesthetics of the highway.
