Gabion mesh is used for road protection.From the perspective of load, the direct cause of road cracking should be the dynamic load transmitted by the vehicle to the road through the tires. Overloading has a greater impact on the damage to the road, but vehicles, especially trucks, have a greater impact on the road when they are unloaded. The dynamic load is also quite large, and the damage to the pavement is also quite large; it is also determined by the external environmental parameters. Experiments on different pavements are compared, and the laying of ecological grids below the surface layer can effectively control pavement cracking and settlement damage.
In order to ensure the strength of the road surface, the ecological grid uses a reinforced ecological grid (as shown in the picture). Generally, steel wires of the same material as the mesh wire are penetrated perpendicular to the weaving direction in the hinged part of the ecological grid mesh, and the diameter of the steel wire is penetrated Not less than the mesh diameter.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.
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.
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
● Construction preparation and planning
Before installing and constructing gabion nets for pavement projects, sufficient construction preparations must be made and a detailed construction plan must be formulated.Construction preparation includes site investigation, material preparation, personnel organization, equipment deployment, etc.The construction plan should clearly define the construction objectives, process flow, safety measures, etc. to ensure the smooth progress of the construction process.
● Basic frame installation
The basic frame is the basis for the installation of gabion nets. Its stability and flatness are crucial to the installation quality of gabion nets. During the installation process of the basic frame, it is necessary to ensure that the frame position is accurate, the size meets the requirements, and appropriate connectors are used To fix.At the same time, the foundation must be compacted and tamped to improve its bearing capacity and stability.
● Gabion processing and filling
According to the construction plan, the gabion net is processed, including cutting, folding, connecting and other processes.During the processing, attention should be paid to controlling the size and accuracy to ensure that the shape and structure of the gabion net meet the design requirements. When filling stones, stones with hard texture and regular shapes should be used, and the principle of layered filling should be followed. Each layer is filled. After completion, compaction processing must be carried out to ensure the tightness and stability of the stones.
● Gabion net fixing and inspection
After the gabion net is filled, it needs to be fixed. The fixing method can use iron wires, connectors, etc. to connect and fix the gabion net with the basic frame or adjacent gabion nets. Periodically, ensure that the connection is firm and stable to prevent the gabion cage from being damaged. If the net is displaced or deformed, after the fixation is completed, a comprehensive inspection of the gabion net must be carried out to ensure that its integrity, stability and filling quality meet the requirements.
● Construction site safety requirements
During the installation and construction process of gabion nets for pavement projects, the safety requirements of the construction site should be strictly observed.This includes setting up obvious safety warning signs, wearing safety protective equipment, ensuring the safe operation of construction machinery and equipment, etc.At the same time, safety education and training for construction personnel should be strengthened to improve their safety awareness and operational skills.
● Regular inspection and maintenance
After the installation of the gabion net is completed, periodic inspection and maintenance work is required.The inspection includes the integrity of the gabion net, the fastening of the connectors, and the stability of the stone.Any problems found must be dealt with and repaired in a timely manner, such as replacing damaged mesh, tightening loose connections, etc.At the same time, the debris and dirt on the gabion net should be cleaned regularly to keep it clean and beautiful.
● Damage and loss handling
During the use of pavement engineering, gabion nets may be damaged or lost due to vehicle crushing, natural disasters and other reasons.Damaged gabions must be repaired or replaced in time to ensure the effectiveness of their protective functions.The lost stones must be replenished and fixed in time to prevent holes or collapse in the gabion net.
● Anti-corrosion and anti-pollution measures
In order to improve the durability of gabion nets, anti-corrosion and anti-pollution measures should be taken.Anti-corrosion measures can be achieved by applying anti-corrosion paint or installing a protective layer to enhance the corrosion resistance of the gabion net.Anti-pollution measures include setting up sewage collection systems and preventing the discharge of harmful substances to reduce pollution and erosion of gabion nets.
To sum up, the installation, construction and maintenance of gabion nets for pavement engineering involve many links and elements.Through the implementation of adequate construction preparations, reasonable foundation frame installation, precise gabion processing and filling, firm fixing and inspection, and strict safety requirements, the stability and protection of gabions in pavement engineering can be ensured. Effect.At the same time, regular inspection and maintenance, damage and loss treatment, and implementation of anti-corrosion and anti-pollution measures are also important guarantees to ensure long-term use and good results of gabion nets.
