Dear scientists and researchers,
There's a standpipe casing which has so many displacement throughout its alignment (bended or misaligned) in the ground. It made the reading impossible since the probe stuck in the displaced section. What's your idea to still receive data from these piezometers?
There's an idea which I want you to check out:
How about adding water to fill up the tube then calculate the amount of water which was there by subtracting total volume from the volume added.
I'd be appreciate it if you would share your ideas.
Thanks
Hi,
Standing piezometers are drilling vertically or obliquely in projects such as dams, etc. However, they are still readable.
If the probe sticks to the wall of the standing piezometers and does not go down the casing, it can be heavier by adding weights to the probe tip.
For solving this problem, such as weights are supplied by the turning and assemble at the probe tip. This trick may solve your problem.
Hi Hamed. First of all I think that we need to know the reason of the bending. Is it due to poor drilling or due to ground movement ( landslide etc). In the first case it seems to me that the only thing that you might be able to do, aside of course of abandoning the borehole, is to remove the old piezometer casing and try to install a new one. Calculating the water volume when you really don't know exactly what portion of the tube you are filling every time (ie where exactly is the blockage, how much water is lost etc) will not give sensible results. In the second case I'm afraid that there is not much that you can do.
Mohsen Mehr Motlagh Thanks but making it more dense hadn't worked out.
Thomas Makedon Thanks for the answer. It's actually in an earth dam. We can't have another piezometer as a replacement then.
wherever the place of bending is, water will rise up (in case there's no blockage just bend) and then we can compare it with previous readings to know how much water rises or lowered since the last reading.
