Description
Summary:During lifting pipeline of horizontal directional drilling (HDD), the rotation angle of pipeline is determined by such parameters as the location of lifting point, axial force, and length of pipeline. The continuous beam theory is used to analyze the mechanical behaviour of pipeline during lifting construction, and the mechanical model of pipeline during lifting construction process is established. The analysis results show that the lifting height of gondola 1 varies linearly with the length of pipeline. The lifting height of gondola 2 varies linearly with axial force and pipe gravity. The longer the spanning pipeline is, the higher the lifting height is. The lifting height of gondola 2 varies curve trend with the axial force and pipe stiffness. When the length of pipeline is small, the lifting height of gondola 2 is approximately 0.
