| Abstract: | Complicated formation condition and underground pipe network condition are the important factors that influence the quality of guided drilling of trenchless technology. The paper presents the key aspects of trenchless technology under complicated conditions,such as accurate technology of directional drilling, the selection and preparation of LG vegetable gum, the choose of pipe, the scientifically calculation of the resistance force of pipe-laying and the design of effective pipe-drawing tool. |
