Quick-mounting device and mounting method thereof

Abstract

The invention discloses a quick-mounting device and a mounting method thereof. The quick-mounting device comprises a pre-embedded sleeve and an externally-formed groove channel; the pre-embedded sleeve comprises a steel pipe provided with an internal thread, a connecting bolt, a fastening bolt, a spring spacer and a square spacer; the connecting bolt is screwed into one end of the steel pipe provided with the internal thread, and is pre-poured in a shield segment; the other end of the steel pipe provided with the internal thread is attached to the inner surface of the shield segment; and the externally-formed groove channel is connected with the other end of the steel pipe provided with the internal thread through the fastening bolt, the spring spacer and the square spacer, so that the externally-formed groove channel is closely attached to the outer surface of the shield segment. The integrity and durability of a shield tunnel are improved, and quick mounting of mechanical and electrical equipment and pipelines in subway tunnels is achieved.

Description

technical field [0001] The invention belongs to the technical field of shield tunnel construction, and in particular relates to a quick-installation device and an installation method thereof. Background technique [0002] With the launching of subway projects in large and medium-sized cities in various places, the shield method has established an absolute dominant position in the construction of urban tunnels, and some people call it the urban tunnel construction method. The original subway pipelines and electromechanical equipment were mostly installed by chemical reinforcement or expansion bolts. However, these prefabricated building methods are relatively simple in design, have low systematic requirements, and have great limitations: chemical reinforcement or Expansion bolts need to be drilled in the existing structure. During the drilling process, structural steel bars may be encountered, which will cause certain damage to the structure itself and affect the durability o...

AI Technical Summary

Problems solved by technology

The original subway pipelines and electromechanical equipment were mostly installed by chemical reinforcement or expansion bolts. However, these prefabricated building methods are relatively simple in design, have low systematic requirements, and have great limitations: chemical reinforcement or Expansion bolts all need to be drilled on the existing structure. During the drilling process, structural steel bars may be encountered, which will cause certain damage to the structure itself and affect the durability of the structure. Chemical planting bars or expansion bolts have a limited life. It is easy to corrode, and generally needs to be maintained or replaced within 15 years of use, which is far from meeting the 100-year durability requirement of the subway; the implanted steel bars or expansion bolts are in contact with the steel mesh, which is likely to cause corrosion of structural steel bars and affect structural safety
