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

Embodiment Construction

[0047]In order to make the object, technical solution and advantages of the present invention clearer, the embodiments disclosed in the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] The invention discloses a quick-installation device for hanging ears, which can be used for the quick-installation of electromechanical equipment and pipelines in subway tunnels, and is specifically the part where shield segment segments are combined on components. The ear holes on the lugs can be directly connected to the anchor bolts used in the concrete segments, which ensures that the lug components can be installed without damaging the concrete segments, so as to achieve the effect of smoothly installing the external chute. The pre-reserved external channel on the external chute facilitates the fine adjustment of the external chute, facilitates the bolt assembly to pass through the connection, and makes the external chute fix...

Abstract

The invention discloses a hanging ear quick installation device and method. The hanging ear quick installation device includes a hanging ear assembly, an external sliding groove and a bolt assembly; the hanging ear assembly includes an ear piece, a hanging part groove and a bolt hole; the ear piece and the hanging part groove are set at a set angle, the bolt hole is formed in the center of the bottom surface of the hanging part groove, and the bolt hole is a counter bore. The bottom surface of the external sliding groove is provided with an external channel and a through hole, the external sliding groove is formed in the hanging part groove, and the bolt assembly is fixedly screwed through the bolt hole after passing through the through hole to make the external sliding groove connected with the hanging ear assembly. The device achieves the rapid installation of electromechanical equipment and pipelines of an iron shield tunnel.

Description

technical field [0001] The invention belongs to the technical field of shield tunnel construction, and in particular relates to a quick-installation device for hanging ears and an installation method. 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 dur...
