Description

technical field [0001] The invention relates to a miniature pipe jacking machine for tunnels, in particular to a central spiral earth pressure balance miniature pipe jacking machine, which belongs to the field of tunnel machinery. Background technique [0002] Many of the current municipal facilities need to be renovated and expanded, especially the old underground pipelines need to be updated, and all kinds of overhead lines on the ground need to be buried underground. However, in the case of very busy ground traffic and row upon row of buildings, if the original large-scale excavation method is still used to transform and build underground facilities to lay pipelines, it will not only destroy the ground buildings, but also have a great impact on the ground traffic environment. The level is very low, and the utilization rate of underground space is also extremely limited, which is not conducive to the protection of various original underground pipelines. It is found throug...
