Geogrids: River Slope Transport & Install- Hash

Описание: Share a Useful Tip: Geogrids for River Slope Protection – Transportation & Installation

Share a practical tip about the transportation and installation of geogrids for river slope protection to boost your knowledge!

What we’re watching is a riverbank protection construction site in a water conservancy project. The honeycomb-shaped grid along the ditch is the renowned geocell! Acting as a custom "protective net" for river slopes, it’s tough, corrosion-resistant, and firmly shields the riverbank once laid. River slopes suffer year-round water erosion and are prone to collapse during rainstorms—this geocell is the river’s "protective shield." Filled with sand, gravel, or soil, it prevents soil loss and enhances slope stability, keeping the riverbank secure. The installation is fascinating: workers unfold the folded geocell beside the ditch, and an excavator gently pushes one end. It slides into the ditch, then "slips and slides" like dominoes due to inertia, extending neatly from one end to the other without section-by-section splicing—super efficient! This practical method is simple and reliable, but how is such a long geogrid transported to the site?

Below is a concise breakdown of its transportation and installation:

Imagine the process as "spreading a huge honeycomb protective net over the river slope," with two key steps: "moving house" (transportation) and "making the bed" (installation).

Step 1: Transportation – "Moving House" for the Protective Net

Though geogrids appear sturdy, they’re vulnerable to damage during transit and require careful handling, like a valuable piece of furniture.

1. Packaging: At the factory, geocells are rolled into large rolls (similar to carpets or bamboo mats) or folded into cubes. They’re then tightly wrapped in thick waterproof woven cloth and secured with ropes to shield against rain, dust, and scratches.
​
2. Transportation: Large flatbed trucks are preferred for their flat, wide surfaces, facilitating easy loading/unloading. A critical rule: never use steel wire ropes for lifting—they’re sharp and can cut the geogrids. Instead, use wide nylon slings.
​
3. On-site Storage: Upon arrival, geogrids must be placed on flat, solid ground, preferably with wooden blocks underneath. Cover them to protect from sun and rain, and avoid overstacking to prevent deformation.

Transportation Summary: Handle with utmost care to ensure intact delivery to the construction site.

Step 2: Installation – "Making the Bed" for the Slope

This is the most exciting part, especially the unfolding—remarkably efficient!

1. Preparation: Clear the slope of debris (large rocks, tree roots) and level the ground, just like tidying a mattress before spreading a sheet.
​
2. Unfolding: Workers place the rolled geocell at the slope top, fix one end, cut the binding ropes, and gently push the other end (with an excavator or manually). It slides down the slope, unfolding "swish" like an accordion or dominoes, covering the entire slope instantly—fast, neat, and splicing-free.
​
3. Securing: The unfolded geocell needs to "grip" the ground. Use special U-shaped or L-shaped ground nails (anchor rods), driving them deep into the soil at grid connections—especially at the slope top, bottom, and middle—at regular intervals to prevent movement.
​
4. Filling & Seeding: Fill the honeycomb cells with soil, sand, or small gravel (slightly above the cell height). If using planting soil, sow grass seeds directly. Once the grass grows, the riverbank gets a "reinforced armor with built-in turf"—sturdy and eco-friendly!

For geogrids (fishing net-like), installation is simpler: unroll them directly, splice adjacent rolls with iron wire or special clips, and fix them to the slope with U-shaped nails.

In Summary

The efficient installation seen in the video relies on careful transportation. The full process: transport with care → clear and level the slope → unfold with a gentle push → secure with ground nails → fill and seed. This completes a sturdy, erosion-resistant riverbank!
