Hello, everyone.
This is Enta.
I’m often asked about the height of the soil foundation for temporary anchors.
I really get asked that a lot!
Is it that few people know this, or do they just forget it right away? lol
I’ll explain the height of a soil retaining wall using temporary anchors.
First, what kind of drilling machine will be used?
If you're going to use a crawler here,±0 is bestThat's it.
However, because of the unevenness of the sheet piles, if you align it with the concave areas, the convex areas will be about 20 cm higher.
The reason the cost increases is that even if the drill holes are at the same horizontal level, the cost goes up if they are located deeper inside.
If you build the earthen embankment based on the recessed areas of the sheet piles, you’ll see that the drilling position ends up higher when the piles are protruding.
Therefore, the standard for the ground surface is based solely on the drilling location at the back.
If the ground level is too low, we won't be able to connect the casing.
In such cases, we use a standing horse, but this significantly reduces work efficiency. (And it's dangerous.)
Also, please cut a groove just before the drilling location.
This way, the drilling fluid flows into the pit area, so the construction yard stays less muddy.
By setting up a pump station at the end of the trench, it will be possible to pump out the drilling fluid from there.
That concludes the temporary earthen platform.
If you ever find yourself doing this kind of work, please use this as a reference.
See you later.
