Is it OK to put copper pipes through sleeper walls?

I am rerouting some 15mm cold water copper pipes under my suspended timber floor. As I am running insulation between the joists, I have found the best way to route these would be through ventilation openings in sleeper walls. I am planning to lag the pipes and support them with talon clips secured to timber blocks, which in turn are secured to the ground.

It will resemble the attached pictures.

Is that OK?

Yeah.
Lagging well and support and all will be fine IMO.
Not my area of expert knowledge though.

I found pipes rubbing against concrete or each other or freezing is the biggest problems.

Put something between timber and the ground. A tile or slate is ideal. There's a (slim) risk that moisture could wick up into the timber and cause it to rot over time.

Yeah, that can create quite a bit of noise. I find using ThermaWrap works quite well for both insulating and cushioning the pipe against walls/concrete/other pipes.

There are some other pieces of original timber touching the ground (cement ground) where moisture has wicked up, like you said, but very slightly. I added a bunch of adhesive underneath the timber as additional securing and also to protect the wood a bit from potential moisture wicking. In another spot, I had already put DPM all accross the floor so the timber is secured (without adhesive) on top of that.
