Analysis on Common Quality Disease and Prevention Measure in Horizontal Directional Drilling Construction
In order to avoid the influence of various unfavorable factors in horizontal directional drilling crossing construction and ensure the smooth completion of the engineering,this paper studies common quality diseases in horizontal directional drilling crossing construction,including the deviation of direction guidance,the phenomenon of slurry,the damage of drilling tools,and the obstruction of back-dragging.According to the causes of the diseases,practical and effective prevention measures are put forward in order to provide reference for the construction of the same type of engineering.
