Imre,

Thank you so much for these so detailed updates. I was wondering how they could deal with those bad anchorage, and concrete wall, and it seems it's only the cap that was faulty and failed. So it's better than having to redrill another full set of anchors.

I feel very confident that the construction will be back on track soon. But really that is (was ?) an incredible accident. Really incredible.

Can't wait for your next pictures. And thanks again for your so precious contribution to this site man ! Really keeps us aware...

Have a nice week,

Krys

WTF? Why is there a digging machine beneath the soil and water?

When this Building ends up on, "Extreme Engineering" or or one of those other Programs. They are going to have one hell of a story to tell.

shouldnt that be moronic engineering? when doing a retaining wall its a good idea to make sure it can hold the water out of the site. its a miracle there were not lots of deaths.

It looks like water is still leaking in. Where is that water coming from?

Not much water left but is still a great mess down there All that rocks and large concrete blocks will take some time to be moved away. I hope it will go fast now.

Ouch! It seems like they are struggling sealing it off!
On the side note, it seems like Hitachi pwned that Komatsu out of place . If Caterpillar is just around

Inclinometer Casing


Model 6500
The Model 6500 Inclinometer Casing is used in conjunction with all commercially available inclinometer probes to monitor the stability of embankments, slopes, rock cuts, foundations and excavation walls, piles, coffer dams, etc. The casings and couplings are pop-riveted together and the joints are waterproofed using caulk and tape. The casing has wheel grooves spaced at 90° intervals, for probe orientation, and is manufactured from pultruded fiberglass ensuring a lightweight, strong, environmentally resistant casing with grooves free from spiraling.

Specifications

Maximum O.D. 70 mm (casing), 76.5 mm (coupling)
Wall Thickness 3 mm (casing), 2 mm (coupling)
Length 3 m (casing), 300 mm (coupling)
Telescoping Coupling available up to 3 m (please specify)


ABS Inclinometer Casing

Geosystems ABS Plastic Casing can be used with all commercially available inclinometer probes to monitor the stability of embankments, slopes, cuttings, excavations, walls, columns, piling and coffer dams. The casing sections are coupled together to produce a strong, accurate, lightweight and corrosion resistant system to monitor ground stability.

Function of Casing



Inclinometer casing is a special purpose, grooved pipe used in inclinometer installations. It is typically installed in boreholes, but can also be embedded in fills, cast into concrete, or attached to structures.

Inclinometer casing provides access for the inclinometer probe, allowing it to obtain subsurface measurements of tilt. Grooves inside the casing control the orientation of the probe and provide a surface from which repeatable tilt measurements can be obtained.

Inclinometer casing is typically installed in boreholes, but may also be embedded in fills, cast into concrete, or attached to structures.


Choosing Inclinometer Casing

Although Slope Indicator casing is competitively priced, price should never be the deciding factor in choosing inclinometer casing. The cost of casing is quite small relative to the cost of mobilizing a drill rig, and very small relative to the cost of a failed installation. This page summarizes the most important factors to consider when choosing casing.

Casing Diameter

Casing is designed to deform with movement of the adjacent ground or structure. The useful life of the casing ends when continued movement of the ground pinches or shears the casing, preventing passage of the inclinometer probe. Larger diameter casing generally provides longer life.

Large diameter casing (85 mm, 3.34 inch) is suitable for landslides and long term monitoring. It is also approprate for monitoring multiple shear zones or very narrow shear zones. Large diameter casing is required when the horizontal probe is used.

Medium diameter casing (70 mm, 2.75 inch) is suitable for construction projects. It can also be used for slope stability monitoring when only a moderate degree of deformation is expected.

Small diameter casing (48 mm, 1.9 inch) is suitable for applications where small deformations are distributed over broad zones. It is generally not installed in soils.


Casing Grooves


Measurement accuracy is directly influenced by the quality of casing grooves. For this reason, Slope Indicator cuts grooves by machine broaching. This process allows the width and chamfer of the grooves to be optimized for the wheels of the Digitilt inclinometer probe and also minimizes spiralling of the grooves.

Casing Strength

In borehole installations, the annular space around the casing is usually backfilled with grout. The grouting process can generate pressures high enough to cause the casing to col-lapse. Stage grouting is one way to avoid this problem. Strong casing is another. Slope Indicator starts with thick-walled pipe and then carefully controls the depth of the grooves during the broaching process to prevent weakening casing walls.

Sealable Couplings


If casing joints are not adequately sealed, grout can force its way into the casing. After the grout hardens, it will prevent the probe from reaching its intended depth. In some cases, the installation will be ruined.

Slope Indicator offers several types of couplings and casings, and all of them can be sealed easily and consistently. Our newest casing features O-ring seals, and our traditional casing features tight-fitting surfaces that are fused together with solvent cement.

Assembly


Inclinometer casing should be easy to assemble, even with an untrained crew. Slope Indicator QC casing, which snaps together, is the current leader in quick and easy assembly. Other types of casing are assembled with shear wires or with solvent cement.

Casing Materials

Slope Indicator uses only ABS plastic for its casing. The ABS formulation is suitable for long term contact with all types of soils, grouts, and ground water. ABS plastic retains its shape and flexibility over a wider range of temperatures than PVC plastic, and ABS is much easier to handle than fiberglass casing. Aluminum casing is no longer recommended for any application.
