The device for constructing the subway station by the mechanical method comprises a plurality of shield tunneling machine units which are arranged in a combined mode, wherein the shield tunneling machine units are detachably connected, the combined shield tunneling machine units are matched with the tunneling tunnel section of the subway station, and each shield tunneling machine unit comprises at least one large-diameter shield tunneling device (1), at least one medium-diameter shield tunneling device (2) and at least one small-diameter shield tunneling device (3). According to the device for constructing the subway station by the mechanical method, underground excavation construction of a subway station tunnel can be carried out, the construction efficiency is improved, the construction safety risk is reduced, the construction quality is improved, the excavation blind area is reduced, the influence on the surrounding environment is reduced, and the construction cost is low.

Description

Technical field [0001] The present invention relates to the field of subway construction techniques. Specifically, a mechanical method is used to build a subway station. It is also a mechanical method to build a construction method of subway station. Background technique [0002] The 21st century is the era of comprehensive development and utilization of underground space. With the continuous development of my country's modernization, the continuous spread of urbanization traffic, the integrated development technology of underground space is continuously promoted in urban subway. In the prior art, most of the subway station uses the construction of the station structure, the construction of the construction subway station structure is high and the advantages of relatively mature work method; however, the construction of the excavation is large, the construction is The surrounding environment has a large influence, it is easy to make traffic jams. The construction of the mushroom ...

AI Technical Summary

Problems solved by technology

In the prior art, most subway stations adopt the open-cut method for station structure construction. The open-cut method has the advantages of high safety and relatively mature construction methods; The surrounding environment is greatly affected, which is likely to cause traffic jams. The risk of underground excavation is relatively high. Due to the advantages of safety, efficiency and high degree of mechanization, mechanical shield construction has gradually replaced the traditional open and underground excavation methods. However, in the process of using traditional shield equipment to excavate tunnels between subway stations, the existing mechanical shield equipment often cannot shield the main structure of the subway station at one time, and the subway station often needs to be separated in the later stage. Construction, this greatly affects the construction efficiency of the subway station structure, and in the process of mechanical shield construction of the subway station, there are often excavation blind spots, and the structure needs to be repaired manually in the later stage. Greatly affected the construction quality and construction efficiency of mechanical shield method construction
