The invention relates to a method for transforming a conventional shield into a tunneling, assembling and synchronous construction shield. The method comprises the steps of main machine transformation and rear matching transformation. According to the step of main machine transformation, a hinged sliding cylinder structure is additionally arranged between a front shield and a middle shield of the conventional shield, and a conventional shield screw conveyor is transformed into a two-stage screw conveyor. According to the step of rear matching transformation, a trolley is additionally arranged and used for arranging an additionally-arranged synchronous grouting tank and a corresponding control cabinet, a secondary grout supplementing device is additionally arranged, and ground surface settlement is effectively reduced; and meanwhile, a movable meeting platform is arranged, two groups of marshalling vehicles can quickly pass through a tunnel, and thus the material conveying efficiency is greatly improved. According to the method, the construction cost is greatly reduced through shield transformation, and the construction efficiency of the shield is remarkably improved through tunneling and assembling synchronous construction.
Description
technical field [0001] The invention relates to the technical field of shield tunneling equipment for tunnel engineering, in particular to a method for transforming a conventional shield tunnel into a tunneling and assembling synchronous construction shield tunnel. Background technique [0002] In recent years, the urban subway shield tunneling project has developed rapidly, and the construction speed has been accelerated; reducing the project cost has gradually become a social requirement. For the shield tunneling project, it is expected to shorten the construction time of the project by realizing the synchronous construction of tunneling and assembly. At present, the shield tunneling project still adopts the principle of step-by-step construction of shield tunneling and segment assembly, and the construction efficiency cannot be improved. At the same time, there are a large number of domestic conventional shield machines, and the cost of newly purchased shield machines is ...
