Detailed Description

The invention will be further explained below with reference to the drawings and examples.

As shown in fig. 1 and 2, the vertical hydraulic pipe jacking machine comprises a top beam 3, a plurality of guide columns 6, a pipe jacking hydraulic cylinder 7 and a base 12, wherein the guide columns 6 are arranged, and as a priority of the embodiment, the guide columns 6 are provided with four guide columns, and the guide columns 6 are arranged in a rectangular shape on the whole. The top beam 3 is provided with two, the top beam 3 is arranged at the top end of the guide upright post 6, and every two guide upright posts 6 are used for supporting one top beam 3. The base 12 is arranged at the bottom end of the guide upright 6. The pipe jacking hydraulic cylinders 7 are arranged on the base 12, at least two pipe jacking hydraulic cylinders 7 are arranged, the telescopic parts, far away from one side of the base 12, of the pipe jacking hydraulic cylinders 7 are connected with the middle beams 4, the middle beams 4 are in guiding fit with the guide upright posts 6, the middle beams 4 are arranged in two, and each middle beam 4 is controlled by the different pipe jacking hydraulic cylinders 7.
