For the micro tunnels with the length of less than 2 meters, the micro tunneling machine or tunnel pipe jacking machine which is mainly used for equipment construction at present is taken as a main representative. The working principle of the heading machine is that the rotation of the cutter head is realized by a motor or a hydraulic motor and a gear box which are arranged in the shield body, and the advancing of the heading machine is realized by an oil cylinder propelling system. The residue soil shoveled in front of the cutter head is stirred by continuously injecting special slurry, and then the residue soil and the slurry are pumped out by a slurry pump.
Currently, most manufacturers only supply a cutter head and an anterior shield system, but a propulsion system and a slurry system are provided by a construction party. Typically the propulsion system comprises the following equipment: (1) a working well matched with construction is convenient for equipment starting and pushing system arrangement, a wall opposite to a tunnel excavation in the working well needs to be pre-supported as the wall is used as a supporting surface for the whole heading machine to advance, and the wall strength meets the design requirement; (2) a set of, typically 4, thrust cylinders and mounting structures are provided. (3) Providing a set of hydraulic pump station, control valve group and pipeline; (4) providing a power supply system with capacity required by the operation of a pump station; and (5) other supporting facilities and systems. After all the equipment reaches a construction site, a power supply is switched on at the construction site, a hydraulic pump station is started, a cutter head of the heading machine is correspondingly started, a hydraulic circuit is opened through a manual controller, a propelling oil cylinder slowly extends out, the heading machine starts to dig a tunnel, the hydraulic circuit is switched after the oil cylinder completely extends out, the oil cylinder slowly retracts, a cement prefabricated pipe joint is inserted between the heading machine and a pushing mechanism, and then the next propelling stroke is started.
The above tunnelling system has the following disadvantages: 1. the strength requirement on the stress wall of the starting well is high, and the production and construction cost is high. 2.
