Geogrid production line equipment. The geogrid is mainly used for soft foundation treatment, subgrade reinforcement, slope protection, abutment reinforcement, wing wall, retaining wall, isolation and reinforced soil engineering on the highway. The geogrid is applied to water conservancy projects such as embankment, dam, river, canal, sea reclamation and reservoir reinforcement. The geogrid can be used to reinforce the soft foundation of building structures in other fields such as garbage site treatment, power plant, ash dam project, coal mine, metallurgy, greening, fence and so on, so as to improve the overall bearing capacity of the foundation. The geogrid can greatly improve the bearing capacity of the runway and ensure the safety of aircraft taking off and landing, Using Geogrid on railway can avoid premature settlement and damage of Railway on soft soil foundation.

Install the geogrid. Means the plan for the layout of the geogrid; This starts at the grassroots level. Cut the specified length of geogrid. Check the manufacturer's specifications and strength of the grid, rolling or steering machine. It refers to the precise size and position of the approved plan. Install the geogrid layer on the raised front lip of the cut edge and the back of the excavation area of the roll layer. The excavation area must be fully compacted and leveled. Compared with steel, geogrid has advantages in corrosion resistance and chemical resistance, but it is vulnerable to ultraviolet radiation, aging or temperature limitation (-50 ℃ ~ +80 ℃).

Therefore, it is necessary to add an appropriate amount of carbon black into the manufacturing material of Geogrid to improve its weather resistance; In addition, it is necessary to take surface protection measures such as filling soil or plants in engineering application to improve the anti-aging performance of geogrid. The geogrid has the characteristics of small elongation and is applied to subgrade reinforcement treatment. Because the polyester warp knitted geogrid is flexible, it can bear large tensile stress. It is arranged in the tensile deformation zone of the soil, and the tensile stress of the drawing is transmitted to the polyester warp knitted geogrid, so that the reinforcement is called a tensile member.

In the process of rolling, when the reinforced soil is under load, the granular materials in the grid mesh are wrapped with each other, and the materials above and below the grid can be organically combined by embedding. The use effect of glass fiber grating is closely related to the treatment of paved pavement. Before paving, the substances on the pavement that may affect the bonding strength between the grating and the bottom layer, such as grease, paint, sealing material, water stains, dirt, etc., must be completely removed to make the paved surface clean and dry.

The pressure sensitive back abdomen on the glass fiber grating is a water-soluble substance. If there is water trace on the pavement, it should be paved after the pavement is dry. Before the grid is laid, tack coat oil shall be sprayed. If emulsified asphalt is used for tack coat oil, the grid shall be laid after complete demulsification and drying. Application of geogrid: it is mainly applicable to subgrade works such as expressway, high-speed railway, retaining wall, port wharf, embankment reinforcement, slope reinforcement, airport runway, etc. it is also applicable to the reinforcement of soft soil foundation, which can greatly improve the bearing capacity, prolong the service life, facilitate construction and greatly reduce maintenance.
