Slope Protection with Gabion Sluice Reinforcement

Slope Protection with Gabion Sluice Reinforcement

Slope Protection with Gabion Sluice Reinforcement

Gabion walls are executed principally for soil stabilization behind the wall, but they can as well as are executed as a cover wall. The wall is constructed from gabion baskets that are contorted in one or more rows, subjecting to the height of the wall. Baskets have a cage pattern and are enclosed on all sides. They are concerned with galvanized hexagonal meshes and broken rock that are situated in the baskets. Retaining structures are coordinated by stacking gabion baskets in an ideal schedule and displaying an alternative solution for concrete structures in the area of soil stabilization.

The gabion can avert damage from water and create a firm life for the vegetation. The gabion can be employed for slope protection. The gabion can be separated into retaining wall, slope protection, bottom protection, toe protection, and subterranean stone blanket. The gabion is quite stable to resist the tension. It can avert soil erosion and keep the nutrition for the plants developing.

Slope Protection functions

There are various ways that gabions are used for slope protection. Some of these functions or applications include:

Retention structures

Gabions retain water at the time of heavy rains and snowfall.

Retention ponds

Gabions are utilized in ponds to prevent erosion and damage affected to the surrounding area.

Dams

Gabions are utilized as dams to store runoff.

Erosion Control

Gabions are utilized for erosion control purposes.

What Are Gabions Employed For?

Gabions are employed for slope stabilization and also for erosion control. They are constructed by covering the cages with stones. The stones function as a barrier and limit the soil from moving upper and lower the slope.

When Should One Use Gabions?

When constructing an afresh slope, you can utilize gabions to help stabilize the area rather than using other retaining walls and barriers. You can as well as use them to stabilize the surface soil to conserve it from a large amount of rainfall. In case your slope already has a lot of vegetation growing in it, you can employ them to protect the area from eroding or sliding by functioning as velocity dissipaters.

How Gabion Retaining Walls Moderate Landslides

Moreover protecting slopes, gabions are utilized to moderate landslides. In regions where there is a risk of landslides occurring, gabions are situated on the soil to create a check dam. The dams curtail and go with the flow of water, by protecting landslides. The soil does not get inundated and hence cannot break away by controlling the water flow. The gabions as well as provide stability to the area around them. They keep the ground in place during allowing water to flow freely, keeping the soils where they belong to.

The construction for the sluice reinforcement with gabion walls

Clean the gabion slope

As per the design, we must clean the trees and also the weeds. In case the excavation area doesn’t conform to the geological exploration report, we must change the construction design according to practical geology.

Install the gabion

We should install the gabion close to the ground and unclosed the gabion unit on the hard ground. The folded portion is neat. We should avoid damage to the gabion and the coating too. We should ensure that the gabion shape is according to the design. The lashing length is nearly from 200 mm to 300 mm.

Filling the gabion

We create high demand for the material standard and the quality to meet the ideal gabion design. We fore mostly fill the gabion one by one and should fill up the gap between the stones when we cover the gabion. The diameter of the stone should be as double as the mesh opening and the quantity of the filler should be more than 1.7 t/m3.

h3>The cover for the gabion

When we have done with the stone filling, the surface must be flat. We would fill the gabion and make the banding when we make certain that the gabion edge is neat.

The gabion construction

The detail is significant and the interval should not exceed 20 cm. The fillers should be as per the standard: the width of the stone is 90–150 mm, and the 50% stone’s width is more than 120 mm. Because of the dense material, the width of the small stone should be 30 mm. The sand content is lower than 5%. The slope and the gabion wall both are made of rocks. We should assure that the filling is substantial and accords with the design and structure.

The sand is filling the gap

Further, the gabion is tested and confirmed, we should overfill the sand until the sand doesn’t decline anymore.

The quality control for the gabion box

As per the demands of the geotechnical cloth design, we should restrict the size of the mesh opening on the slope. The four groups and apportion should be erect. We should combine the cover and the group. And we should build up from the left to the right and fill up the plating soil in the gabion. Certainly, it shapes the gabion slope protection.

The advantages/Benefits of the gabion

The gabion can abide the impact force from the billow. The gabion can keep the water flow speed at 6 m/s. The scouring resistance capability is better than the masonry and the usual concrete.

The design of the gabion owns good flexibility and is of high stability. The gabion is extensible and is of good ductility.

The gabion has erosion resistance. When the water is destructive or the river is contaminated, the gabion on the upstream is enclosed with PVC or PE. This material has a great service life and can protect the metal from corrosion.

It’s simple to install the gabion box. We don’t require cement, electricity, or even a model. And the temperature couldn’t change the construction. We can make utilization of the local resources to assemble the gabion.

The construction is affordable and there is no purchase and transformation cost which reduces the cost to a great extent.

The gabion averts the local ecological balance. The gabion can fit well with the local vegetation. This can increase the aesthetic of the city. We can as well as plant the vegetation in the gabion and it would prevent the bank and also prevent soil erosion.
