Hello, everyone.
This is Enta.
It's been getting really cold lately.
Since this is important, I'm reposting a previous article lol
This job site was particularly cold, and the water kept freezing over and over again.
It’s still okay during the day, but it gets especially cold in the mornings and evenings, and since I wanted the grout to set quickly, I used hot water.
It kept getting colder and colder as it came into contact with the outside air, but even at the final outlet, it was only lukewarm. (I didn't measure the temperature.)
Since the ground is warmer than the outside air after injection, it is believed that the material cured stably without the temperature dropping significantly.
As the saying goesImmersion HeaterIt's a more powerful version of that, isn't it?
At 200V, about 1 cubic meter of water will reach around 40 degrees in a few hours. (You could just keep adding water, but the thermostat for this model is sold separately and is pretty expensive... so if you don't add water, the temperature just keeps going up lol.)
By evening, it had gotten so hot I couldn't touch it, so I kept adding water as needed.
When I mixed it using that hot water, it ended up at about this temperature.
It's really hard to take the temperature—sometimes it goes up just while I'm writing on the blackboard, lol.
It's tough because the thermometer can't be locked. Haha.
By the way, the submersible heater I'm using is
I used this 15 kW L-shaped model. (I bought it, and it was pretty pricey.)
See you later.
