Problems solved by technology

[0003] The current production process of reinforced concrete segments is basically as follows: steel mold→reinforced cage→concrete pouring and ramming→steam curing→hoisting and demoulding→water pool maintenance→natural maintenance of the outlet pool→product inspection; according to the current production method of reinforced concrete segments After pouring and stamping, the segment needs a long maintenance time in the pool and after exiting the pool, generally more than ten days, and the period for the segment to be put into use is long; moreover, the maintenance process of the pool and after exiting the pool must take up a lot of time. The factory site, the overall efficiency is poor

Embodiment 1

[0045] Such as Figure 1-7 As shown, in this embodiment, a shield tunnel segment is provided, which mainly includes a segment shell 1 and a steel cage 2 arranged in the segment shell 1, and the steel cage 2 is fixedly arranged by pouring concrete 3. In the tube shell 1.

[0046] Specifically, the tube piece housing 1 is composed of a front wall piece 11, a rear wall piece 12, an upper wall piece 13, a lower wall piece 14, a left wall piece 15 and a right wall piece 16. The front wall piece 11, The rear wall piece 12, the upper wall piece 13, the lower wall piece 14, the left wall piece 15 and the right wall piece 16 are all made of high performance concrete (HPC) or ultra high performance concrete (UHPC); wherein, the front wall piece 11. Any five of the rear wall piece 12, the upper wall piece 13, the lower wall piece 14, the left wall piece 15 and the right wall piece 16 are assembled to form a receiving cavity 17 with a unique opening, and the remaining one is detachably arra...

Embodiment 2

[0062] The same parts as in Example 1 will not be repeated, such as Figure 8 As shown, this embodiment provides a shield tunnel segment, which also includes a segment shell 1 and a reinforcement cage 2 arranged in the segment shell 1. The reinforcement cage 2 is fixedly arranged by pouring concrete 3 In the tube shell 1.

[0063] Specifically, the tube piece housing 1 in this embodiment is annular, and is composed of an inner wall piece 51, an outer wall piece 52, a first side wall piece 53, and a second side wall piece 54; the inner wall piece 51 Any three of the outer wall piece 52, the first side wall piece 53 and the second side wall piece 54 are assembled to form a receiving cavity 17 with a unique opening, and the remaining piece is detachably arranged at the opening of the receiving cavity 17 to close The containing cavity 17.

[0064] Further, the main difference between the manufacturing method of the tube shell in this embodiment and the tube shell in embodiment 1 is:

Abstract

The invention provides a shield tunnel segment. The shield tunnel segment comprises a segment shell and multiple reinforcement cages, the segment shell is formed through splicing of a front wall piece, a rear wall piece, an upper wall piece, a lower wall piece, a left wall piece and a right wall piece, the front wall piece, the rear wall piece, the upper wall piece, the lower wall piece, the leftwall piece and the right wall piece are made of high-property concrete or ultra-high-property concrete, any five in the front wall piece, the rear wall piece, the upper wall piece, the lower wall piece, the left wall piece and the right wall piece are spliced to form a containing cavity with a unique opening, one remaining piece can be detachably mounted on the opening of the containing cavity, the reinforcement cages are embedded in the containing cavity from the opening and are poured and fixed through concrete, according to the segment, a steel mold forming manner in a traditional segment manufacturing process can be replaced, on the premise of ensuring design strength needs, the manufacturing engineering time of the segment can be effectively shortened, the segment manufacturing cost can be effectively reduced, and the whole economic benefits can be improved.

Description

Technical field [0001] The invention belongs to the technical field of tunnel engineering, and specifically relates to a shield tunnel segment and a manufacturing method thereof. Background technique [0002] With the rapid development of urban subway construction in China, and subway construction in the city, the requirements for civilized construction, ground subsidence control, and building protection are relatively high. Due to the high degree of mechanization of shield tunnel construction technology, the construction safety factor is relatively high. High, it can minimize the impact on other urban facilities, so it has gradually become the mainstream technology of subway tunnel construction; shield segment is the main assembly component of shield construction, is the innermost barrier of the tunnel, and bears resistance to the soil layer The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment is directly related to the ove...
