Further, a circular steel plate or a wood plate is arranged at the end opening of the jacking pipe, and an oil cylinder groove is formed in the circular steel plate or the wood plate; the steel plate or the wood plate is arranged, so that the purpose of reducing stress is achieved, and the possibility of damaging the pipe is reduced.
Further, circular ring shape steel sheet and plank have set gradually in push pipe port department, are provided with the hydro-cylinder groove on the steel sheet, through setting up steel sheet and plank to reach the purpose that the stress subducted, reduce the possibility that tubular product destroyed.
Further, circular ring form plank and steel sheet have set gradually in push pipe port department, are provided with the hydro-cylinder groove on the plank to reach the purpose that stress subducted, reduce the possibility that tubular product destroyed through setting up plank and steel sheet.
Further, the thickness of the wood board is 10-30 mm; the thickness of the steel plate is 30-50 mm.
Has the advantages that: the position of the pipe-jacking oil cylinder groove is stressed greatly, and when the oil cylinder is installed to be stressed and get rid of difficulties, the pipe jacking around the oil cylinder groove needs to be reinforced and padded to achieve the purpose of reducing stress, so that the possibility of damage to the pipe is reduced. The utility model discloses an outer steel ring is consolidated, utilizes steel sheet and/or plank to carry out the liner or consolidate around the hydro-cylinder groove to reach the purpose that stress subducts, reduce the possibility that tubular product destroyed.
