| Abstract: | Communication pipe playing construction case with trenchless horizontal directional drilling technology in KaifengLuoyang express highway was studied. Field drilling experimental data were analyzed. That the borehole track of horizontal directional drilling is arc is concluded. Calculating formula of borehole arc curvature radius and inlet elevation angle assuring borehole outlet exactly are induced. Main technological points of horizontal directional drilling are summarized in the paper. |
