The application of total station in the engineering setting out and checking;

And combined with real projects,it illustrates the features and steps of measuring and setting-out in polar coordinate setting-out method and connecting traverse setting-out method,which enhances people s knowledge about the two methods and meanwhile makes measuring and setting out faster and better.

This paper discusses the use of total station in Yin\|Han first class highway setting out, it has given some advices about setting out.

In terms of the disadvantages in the take-up/pay-off operation for copper conductor PVC insulated wires(short as installation wire),technical improvement was made.

Aimed at the characteristics of large cross section and quality of unit length of type ACSR-720/50 line,the construction scheme is submitted through which the techniques of pay-off,tension stringing and accessories section installation are compared.
