Description
Technical Field
The utility model belongs to the technical field of shield tunnel section of jurisdiction is assembled, especially indicate a section of jurisdiction after being used for the tunnel to tear the machine open and assemble device.
Background
After the shield tunnel is communicated and the tunnel inner dismantling machine is finished, the inner supporting structure of the shield body is cut off, the shield shell can be left in the excavated tunnel, and at the moment, the space of about 7-10 meters left in the position of the shield shell is not spliced by the segments, so that the segments are difficult to splice due to the limitation of the field in the tunnel. In order to realize the assembly of the segment, two modes of a movable mounting vehicle and a cast-in-place lining are adopted at present.
In the existing mode, although the cast-in-place lining mode has wide applicability, the material is difficult to transport in the tunnel, and the material cost is high; the construction efficiency is low, and supports and molds need to be built on site; the construction condition in the tunnel is poor, the labor demand is large, and the later cleaning is difficult; the quality can not be guaranteed, and the maintenance time is longer. The mobile installation vehicle needs to be additionally provided with a rubber-tyred vehicle, the erector is carried on the rubber-tyred vehicle, the erector is not easy to be fixed on the rubber-tyred vehicle, and the erector needs to move in each degree of freedom relative to the rubber-tyred vehicle, so the safety coefficient is low.
Therefore, the duct piece assembling device used after the tunnel dismantling machine is urgently needed, the construction quality can be guaranteed, the construction cost is reduced, and the construction safety factor is increased while the construction efficiency is improved.
