Abstract

The invention discloses a pipeline jacking device, which is placed in an originating shaft. The pipeline jacking device includes a base; a fixed back plate, which is vertically fixed on the base, and the fixed back plate is closely attached to the starting shaft. The side wall of the hair shaft; the fixed back plate is provided with several rings of mounting holes in the circumferential direction, which are used to install the guide rods. The mounting holes of the adjacent two rings correspond to each other, and each ring of mounting holes is distributed in a ring shape; a guide rail, It is arranged on the base; at least one propulsion mechanism, under which the pipeline moves along the guide rail toward the jacking direction; and a guide mechanism. The present invention provides the guide mechanism, which uses two circles of guide rods to form two rings, and the space between the two rings is used to clamp and accommodate pipelines, guide and limit the pipelines, and avoid misalignment of the pipelines during the jacking process deviation.

Description

technical field [0001] The invention relates to the field of pipe jacking construction. More specifically, the present invention relates to a pipe jacking construction equipment and construction method. Background technique [0002] Pipe jacking construction is a non-excavation construction method, which can realize pipeline burial under the premise of no excavation or less excavation. It overcomes the friction between the pipeline and the surrounding soil by means of the jacking force generated by the jacking equipment in the working well. The friction force pushes the pipeline into the soil according to the designed slope and direction, and transports the soil away. After one section of pipe has been jacked into the soil layer, the second section of pipe continues to be jacked. The principle is to push the tool pipe or roadheader through the soil from the working well with the help of the thrust of the main jacking cylinder, the pipe room, and the relay room. The layer i...
