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

[0043] 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.

[0044] 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 hanging lugs can be directly connected with the anchor bolts used in the concrete segments, which ensures that the hanging lugs can be installed without damaging the concrete segments, so as to achieve the effect of smoothly installing the external chute. The T-shaped bolts are tightly connected to the U-shaped grooves set on the hanging piece groove through the groove of the external chute, and are tightened and fixed by nuts, so that the external...

Abstract

The invention discloses a lug rapid installation device and an installation method thereof. The lug rapid installation device includes a lug, an external sliding groove and a bolt assembly, wherein the lug includes a part hanging groove, a U-shaped groove formed in the bottom face of the part hanging groove and a lug piece, the included angle between the lug piece and the upper surface of the parthanging groove is an acute angle, the external sliding groove is installed in the part hanging groove in a nested mode, and the bolt assembly passes through the U-shaped groove and connects and fixesthe lug and the external sliding groove. According to the lug rapid installation device and the installation method thereof, rapid installation of electromechanical equipment and pipelines in a subway shield tunnel is realized.

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 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...
