Problems solved by technology

[0003] To limit the position, this method is to preset a semicircular groove on the surface of the block, and set a positioning rod in the groove when assembling. This method is slightly improved compared with the original design, but it increases the cost of segment mold manufacturing. The connecting bolts are also not effectively protected

Embodiment Construction

[0040] The features of the present invention and other related features will be further described below with reference to the accompanying drawings.

[0041] like Figures 6-1 to 6-6 As shown in the figure, a shielded segment assembling positioning tenon sleeve is composed of two circular troughs with the same bottom surface and overlapped connection. The positioning tenon sleeve is embedded with a steel sleeve 2, and the positioning tenon sleeve is axially provided with a connecting cavity 1. The connecting cavity is composed of The cylindrical cavity 8 in the middle and the trumpet cavity 9 on both sides are formed.

[0042] The tapers of the two circular troughs are different, one of which is provided with a number of annular adhesive grooves 3 on the outer side, the annular adhesive grooves are arranged on the outer side of the circular truncated 4 with a smaller taper, and the other circular truncated 5 with a larger conic The outer surface is composed of an outer tapered ...

Abstract

The invention relates to a shield segment assembling positioning tenon sleeve and application thereof in shield segment assembly and belongs to the technical field of nylon product processing. According to the shield segment assembling positioning tenon sleeve and the application thereof, a complex shield segment design of applying a positioning rod or a rebate groove in the prior art is abandoned. At the position of the side of a shield segment (a connecting surface) where a positioning groove is prefabricated, the positioning tenon sleeve is installed between two segments to be used for mounting and limitation, an arc-shaped connection bolt can be effectively protected while the segment construction assembling positioning requirements are met, a steel die design processing process is optimized, a steel sleeve is embedded in the positioning tenon sleeve for production, and segment assembling ring formation construction quality is effectively ensured.

Description

technical field [0001] The invention relates to a shield tunnel segment assembling positioning tenon sleeve and its application in shield tunnel segment assembling, belonging to the technical field of construction nylon product processing. Background technique [0002] When the shield segment is assembled during construction, in order to prevent the phenomenon of "wrong platform" during assembly, it will affect the construction assembly, the stress state of the structure, and the waterproof effect, which will seriously endanger the safety of tunnel construction. like Picture 1-1 , 1-2 As shown in the figure, in the initial design of the shield segment, the concave and convex tongue and groove were designed on the block surface (connection surface) to ensure the limit when the segment was assembled. Although this design is convenient for construction and assembly, it brings about structural design and production costs. Negative Effects. To reduce this impact, such as Fig...
