Thanks for the translation.
I would like to supplement that one of the important things in setting up this type of laboratory is the selection of right sonic logger with suitable energy emission level; otherwise, it may be difficult to perform the test for large diameter bored piles and the capacity of your laboratory will be limited (and will consequently limit your ability in earning money).
I am not good in Chinese and consider that the translation is basically correct except the following suggestions:
Cable – the cable is not made with optical fibre, but ordinary 导线 or just called 电线 (by the way, I wonder why the wireless phone is called 无绳电话, not无线电话 in Mainland China)
Crosshole – 跨孔
Centralizers adjustable to ....... - 可调置中器(?)
“100 m measuring type with weight” is not a formal term for this kind of tool (I forgot the proper name), what I mean is a 100 m 测深钢卷尺
