[0001] The invention relates to a portable leveling rod bracket, in particular to a portable bracket used in conjunction with a precision Invar barcode leveling rod. Background technique
[0002] In the construction of roads or railways, engineers often need to carry out various engineering measurements on the terrain where the roads or railways are located, and precision leveling is one of the important measurement items. We know that these measurements must be carried out outdoors. However, the outdoor environment is generally poor, especially in windy weather. In addition, the quality and external dimensions of the precision Invar barcode leveling rod itself are relatively large. It is difficult to straighten the leveling rod, which directly leads to a large measurement error. In addition, the entire measurement process relies on human hands to support the leveling rod, which is labor-intensive and causes natural trembling of the human body, which increas...
