Research on application of non-destructive detection technique to quality of grouting for engineering anchor bars;

Technical and economical analysis concerning the anchor bolt works at Three Gorges Project ship lock;

The primary supporting structure design of steel bracing and bored piles was changed into LXK constructing method anchor and bored piles in Modiesa station excavation of Guang Zhou Metro II.

Experimental study on grouting material of early-strength silicate cement for anchor engineering;

Using sodium chloride,sodium sulphate,three-ethanol amine,sodium silicate,silica ash,fly ash as the additive of cement,the modification of the common cement slurry for anchor engineering was studied.

It is a new drilling method and is used generally in the anchor engineering of soil and rock.
