Background The pipe jacking technology is a non-excavation construction method for penetrating a pipeline through barriers such as soil, rocks, rivers, roads, buildings and the like by utilizing the jacking force and the self weight of the pipeline, so that the purpose of tunnel excavation or pipeline laying is achieved, and the pipe jacking technology is widely applied to tunnel excavation. Before jacking construction of the push pipe, the starting gradient of the push pipe needs to be adjusted so as to accurately control the jacking direction of the push pipe machine and ensure the smooth pushing of the push pipe machine and the tunnel excavation quality. At present, the adjustment of the gradient of the jacking pipe generally adopts two methods of height adjustment of a jacking pipe moving track and installation of a gradient adjustment device at an initial position of the jacking pipe, wherein the height adjustment of the jacking pipe moving track mainly comprises the step of filling iron felts with different numbers or different heights below the track to change the gradient of the track so as to change the gradient of a pipeline installed on the moving track, but the gradient adjustment precision is lower due to the limitation of the height of the iron felts, and the iron felts are easy to deform after being subjected to multiple actions of multiple sections of pipelines, so that the gradient of the pipeline is influenced. The existing gradient adjusting device mainly utilizes jacking equipment such as a jack to change the heights of two ends of a pipeline so as to adjust the initial gradient of a jacking pipe, but the jacking structures have certain heights and can only drive the end part of the pipeline to move upwards, so that the angle of the initial gradient adjustment of the jacking pipe and the initial height of the jacking pipe are limited, and the flexibility of the initial gradient adjustment of the jacking pipe is poor. Therefore, there is a need for a jacking pipe originating gradient adjusting device and adjusting method to solve the above problems.
