The invention discloses a non-horizontal pipe jacking construction method, and relates to the field of non-excavating pipe jacking construction. A guide pipe is pre-buried in a wall of a starting wellaccording to a design elevation and a pipe jacking slope; on a bottom plate of the starting well, a guide base with the same slope as the pipe jacking slope is constructed, and a guide rail used forpipe jacking is arranged on the guide base; a wedge-shaped backrest is built on the inner surface of a pipe jacking rear seat of the starting well, and the face, away from the pipe jacking rear seat,of the wedge-shaped backrest is perpendicular to the working surface of the guide base; and when the pipe jacking operation is carried out, a pipe joint is hung on the guide rail of the guide base, the front end of the pipe joint is in butt joint with a pipe head of a jacked pipe, the rear end of the pipe joint is connected with an execution end of a jack set through a front-end pressure dividingring, when ready, pipe jacking work is carried out, the pipe joint is pushed out by the execution end of the jack set, the pipe joint enters a hole along the pipe jacking slope, and non-horizontal andlarge-slope pipe jacking construction is realized.
Description
technical field [0001] The invention relates to the field of trenchless pipe jacking construction, in particular to a non-horizontal pipe jacking construction method. Background technique [0002] Pipe jacking construction is a construction method that adopts the non-excavation method of laying pipelines, that is, using manual or pipe jacking heads to excavate horizontally in the working well of the pipeline design; The muck is transported outside until the pipe jacking is completed. This method effectively solves the problems of damage to original buildings and blockage of traffic roads during pipeline burying construction, and creates a beautiful environment for civilized construction for urban construction. [0003] The general pipe jacking projects are mostly horizontal pipe jacking or pipe jacking with a small slope. The pipe jacking with a small slope can be pushed by adjusting the orientation of the pipe jacking head. The offset distance adjustment arc of the pipe h...
