Hello, everyone.
This is Enta.
Wasn't the weather in Hokkaido absolutely beautiful and clear just the other day?
It gets quite chilly in the mornings and evenings, but the weather is pleasant.
I'd like to make sure I don't get sick from the changes in temperature.
It's cloudy today, and it's drizzling a bit.
But that's beside the point.
Why are you measuring the deflection of the load-bearing plate?
If a verification test is being conducted at a fixed point, the load-bearing plate will lower. (In the case of load-bearing structures with variations.)
Since the measurement is taken from a fixed point, we can obtain the data for the elastic displacement curve as usual.
Therefore, we can plot the elastic displacement-strain curve.
By the way, do you know what the data from this dial gauge attached to the pressure plate is used for?
Actually...
There's absolutely no use for it at all!
The load-bearing plate sank 2 centimeters, didn't it?
It just feels like it sank about 3 centimeters~~.
Anyway, the datasheet for plotting the displacement curve also has a section for compression-bearing structures, lol.
There aren't any specific guidelines for managing structures under compression—it's more a matter of ensuring the bearing capacity of the soil is sufficient.
This pressure plate has settled about 1 centimeter, but it has now settled in and stabilized.
That's all there is to it.
To monitor that by attaching a dial gauge...
Well, since there are people who think that's fine, I won't argue with it.
However, in my case, I do it when it sinks. This is because the system is designed with hydraulic cylinder stroke control in mind, so,
You need to subtract the amount that has sunk.
If the load-bearing plate sinks, the jack will sink as well. Therefore, if you don’t subtract the amount of sinking, you may not get an accurate reading.
However, do not install it if the structure under pressure is a retaining wall or similar structure.
If this shifts even a little, it’ll cause a whole new set of problems—it’s that serious, lol.
Construction management doesn't mean you just have to do everything and anything.
There's absolutely no need to put so much effort into doing something pointless.
It’s more meaningful to do what’s necessary thoroughly and reliably.
What’s important, and what isn’t? I think it’s important to figure that out.
Time is limited, after all. Let's use it wisely.
See you later.
