Soil nailing

Micropiles, used as soil nails, are utilized to stabilize slope sections, unstable slopes, and embankments, as well as to provide temporary and permanent anchorage for shotcrete facings, secure excavations, and refurbish retaining walls. One significant advantage of soil nailing over traditional retaining structures is its ability to accomplish stabilization without requiring additional excavation.

Equipment selection can be tailored to fit local conditions, ensuring that nearly every drilling position can be accessed with appropriate tools.

Head details are chosen based on the specific application, providing flexibility for temporary or permanent installations with or without angle compensation, utilizing system components as required.

The various possibilities for soil nailing are:

Slope stabilization Excavation shoring Transport infrastructure Retaining walls

Slope stabilization

In slope stabilization projects, our system is commonly employed alongside high-strength wire meshes to reinforce the surface. Often, anchors for the wire mesh are installed concurrently with rockfall fencing, which is also secured using micropiles. It is essential to galvanize all exposed steel components to prevent corrosion.

Slope stabilization applications:

  • Stabilizing unstable slopes and crucial earth embankments
  • Rockfall protection measures
  • Protecting structures and infrastructure

Excavation shoring

Using micropiles for temporary and permanent excavation shoring with anchored shotcrete facing can be customized to local conditions without the need for heavy equipment. The excavation is secured incrementally, as work progresses.

Transport infrastructure

Railways
Micropiles can be used as soil nails to stabilize embankments, whether natural or man-made, alongside railway lines. They enhance stability both above and below the tracks. Similarly, micropiles applied as soil nails can improve the stability of elevated railway track embankments.

Roads
Micropiles can stabilize slopes both above and below a road when used as soil nails.

Canals
Embankments next to canals can be stabilized using micropiles as soil nails instead of sheet pile walls. Another option includes applying shotcrete facing with anchored wire mesh to promote vegetation growth.

Retaining walls

Micropiles used in conjunction with retaining walls are commonly employed for soil nailing in slope stabilization projects. Existing structures are often renovated using this method. Compared to typical anchorages for retaining structures according to DIN EN 14199, this approach involves smaller grids, lower loads, and shorter elements.
