Palisade structure for underground architectural shaft and shield machine cutting construction method thereof

Abstract

The invention discloses a palisade structure for an underground architectural shaft, which has a reinforcement structure formed by connecting an upper reinforcing cage, a middle FRP reinforcing cage and a lower reinforcing cage. The invention also discloses a shield machine cutting construction method of the underground architectural shaft palisade structure, which comprises the following steps: after hoisting, overlapping and binding the lower reinforcing cage, the middle FRP reinforcing cage and the upper reinforcing cage, concreting to form the underground architectural shaft palisade structure; and when the shield machine advances to a position of the FRP reinforcing cage of the underground architectural shaft, replacing the cutter of the shield machine by a hob, a serrated knife or a scraper blade, and then cutting the palisade structure for the underground architectural shaft. The palisade structure and construction method of the invention can accelerate the construction progress of the underground buildings, and reduce the wear of the blade of the shield machine to a certain extent, thus, the method is suitable to be popularized in the palisade structure of the underground architectural shaft passed in and out by the shield machine.

Description

technical field [0001] The invention relates to an enclosure structure, in particular to an enclosure structure for an underground building shaft. [0002] The invention also relates to a shield machine cutting construction method for the underground shaft enclosure structure. Background technique [0003] my country's urban construction land is increasingly scarce, and underground buildings such as underground garages and commercial streets have become an inevitable development trend. The construction of tunnels and structures for underground buildings frees up more land space for the urbanization process. At present, underground buildings usually use steel bars or steel plates as the enclosure structure of the reinforcement to achieve the purpose of water stop, seepage prevention, and load bearing. The shield tunneling method must be selected for underground building construction. However, in shield tunnel construction, when the tunnel is excavated to the position of the...

Problems solved by technology

At present, the treatments adopted include high-pressure rotary spraying method, deep mixing method, chemical grouting method or freezing method, etc., which not only increases the construction cost of the shaft enclosure, but also prolongs the construction period; it also puts forward higher requirements for the working face of the shaft construction. requirements, the impact on surrounding traffic and buildings increases
