Abstract
The invention discloses a lap joint, injection molding and coating device for geogrid cross nodal points and a production method. The device is characterized by comprising an upper formwork and a lower formwork, the opposite end faces of the upper formwork and the lower formwork are provided with upper formwork blocks and lower formwork blocks respectively, the upper formwork blocks and the lower formwork blocks correspond to cross points of strips, and sinking regions of the upper formwork blocks and the lower formwork blocks are larger than the cross points of grooves of the strips; after the strips are filled with grooves, filling spaces are correspondingly formed between the upper formwork blocks and the strips and between the lower formwork blocks and the strips; an injection opening is formed in the upper formwork or the lower formwork, flow channels are formed in the corresponding end faces of the upper formwork blocks and the lower formwork blocks, and the flow channels face toward and are communicated with the filling spaces. The coated nodal points are formed by injecting inwards through the injection opening, and compared with the prior art, the lap joint, injection molding and coating device has the advantages of being good in production effect, low in cost and high in strength.
Description
technical field [0001] The invention relates to the field of geotechnical engineering construction-a geogrid cross-joint joint injection molding coating device and a production method. Background technique [0002] Geogrids are mainly used in geotechnical projects such as highways, railways, airport construction, docks, land reclamation, water conservancy dams, etc. After the roadbed backfill is reinforced, the integrity is stronger, and it is not easy to crack, sink and shift. It ensures the quality and safety of the project, and is one of the preferred new geotechnical building materials today, providing a strong guarantee for the century-old project. [0003] At present, there are many kinds of production methods for reinforced materials used in geotechnical engineering, and their mechanical properties and adaptability to the environment are different. There are three main types of plastics: [0004] 1) Plastic stretching type: such as unidirectional and biaxial stretchi...
