Drilling Depth and Machine Size in Ground Anchor and Rebar Insertion Work (Part 1)
Depending on the machine you choose, there are cases where it can be used on-site and cases where it can't, right?
While deciding on a construction method is important, it’s also important to understand the machinery involved.
It's kind of funny that only the contractors know which machines can do the job, lol.
Both project managers and consultants should make sure they have a clear understanding of how to select the right equipment, so that...
I believe we can make full use of the construction methods and their benefits.
Drilling diameters of φ90 or larger that require scaffolding
Drilling depth: approximately 7 m or more
(The photo shows that construction can be carried out on a dirt site without using a crawler.)
For drilling holes deeper than 7 meters, small (in some cases), medium, and large-scale machines are used.
Given this size, the monorail's 500 kg capacity is going to be quite a challenge.
For a monorail, you need a specification with a 3-axle load capacity of 2 metric tons or more!
The size of the machine depends on the drilling length, but the drilling diameter is the key factor.
In the case of a minimum double-pipe diameter of φ90, the machine size is on the smaller side, so it’s manageable, but,
As the diameter increases, the overall size and weight of the machine change significantly.
I think medium-sized aircraft are generally used for anchors longer than 10 meters.
In terms of weight,Approximately 2 metric tons or more—
When it comes to large aircraft,3 metric tons and up
Naturally, since the hammer is larger, construction efficiency improves, but,
When you factor in the transportation involved, it becomes quite a challenge.
When it comes to large-diameter ground anchors, the machinery also gets larger, so
If we don't plan the route carefully, we might end up in a situation where we can't get the machinery in—so what are we going to do?? lol
See you later
