Description

Technical Field

[0001] This invention patent relates to the fields of slope reinforcement and lattice beam installation technology, and in particular to a node connection device for lattice beam installation. Background Technology

[0002] With the increasing number of construction projects, the demand for slope excavation has also grown significantly. Excavation of slopes can affect the stress on the slope structure. In response, many slope reinforcement measures have emerged in China in recent years. The anchor cable (rod)-grid system is a retaining structure that combines grid beam slope protection with anchor cable anchoring mechanism. In China, when using this method to reinforce slopes, grid beams are often divided into cast-in-place and precast types.

[0003] For cast-in-place lattice beams, the manufacturing process is more complex and the curing time is longer, resulting in a longer construction period. The harsh environment at the field construction site makes it difficult to guarantee the quality of lattice beams manufactured using the cast-in-place method. After the cast-in-place method is completed, the prestressed anchor cables (rods) can only be tensioned after the concrete has reached its strength, which delays the construction period and increases costs.

[0004] For precast lattice beams, they can be prefabricated in a factory and then transported to the site for assembly, which greatly saves time and costs, and the process is standardized, making them particularly popular in recent years. However, when assembling them on slopes, the reserved anchor cable (rod) holes may deviate from the reserved positions in the precast lattice beams during actual construction, and the assembly joints are very weak. Long-term use or exposure to external loads may lead to structural damage and protective failure. Summary of the Invention
