Embodiment 1

[0034] Such as figure 1 As shown, a segment joint device for a rectangular shield tunnel in this embodiment includes a first joint box 100 , a second joint box 200 and a connecting piece 300 .

[0035] Such as Figure 6 As shown, the first joint box 100 of this embodiment includes a first open box body 110 and a first anchor rib 120, as Figure 3 to Figure 5 As shown, the first open box body 110 of this embodiment has at least a first bottom plate 111, two first side plates 112 and a first end plate 113 arranged opposite to each other, and the first side plate 112 and the first end plate 113 They are all arranged on the same side of the first bottom plate 111, and the first end plate 113 is located between the two first side plates 112. A number of first connecting holes 114 are opened on the first end plate 113, and a number of first anchor ribs 120 are set respectively. On the first side board 112 and the first bottom board 111 .

[0036] Specifically, such as image 3 A...

Embodiment 2

[0045] This embodiment also proposes a segment joint structure of a rectangular shield tunnel, which is applied to the splicing of the adjacent first segment and second segment on the rectangular shield tunnel. The segment joint structure includes several sets of implementations. For the segment joint device of the rectangular shield tunnel described in Example 1, the specific structure of the segment joint device can refer to the specific description in Embodiment 1, and will not be repeated here.

[0046] Such as Figure 7 and Figure 8 As shown, the first open box body 110 of this embodiment is embedded and anchored in the first tube piece 400, the first anchor bar 120 is anchored and connected with the inside of the first tube piece 400, and the outer surface of the first end plate 113 is connected to the first tube piece 400. The abutting surfaces of a segment 400 are arranged flush, and the opening of the first open box body 110 opposite to the first bottom plate 111 is...

Abstract

The invention discloses a segment joint device and a segment joint structure of a rectangular shield tunnel. The segment joint device comprises a first joint box, a second joint box and a connecting piece; when the segment joint device is used, the outer side face of a first end plate is attached onto the outer side face of a second end plate, and a first connecting hole is communicated with a second connecting hole in a butt joint mode; the connecting piece is arranged on the first connecting hole and the second connecting hole in a penetrating mode, so that the first joint box and the second joint box are connected into one body. The segment joint structure is applied to the joint of a first segment and a second segment which are adjacent on the rectangular shield channel, and the segment joint device is utilized for jointing the first segment and the second segment into one body. The requirement for the segment connection of the rectangular shield channel is met, so that the requirement for the safety and durability of the structure can be met in the construction period and the normal use period of the rectangular shield channel respectively.

Description

technical field [0001] The invention relates to the technical field of tunnel segment connection by shield tunneling method, in particular to a segment joint device and a segment joint structure of a rectangular shield tunnel. Background technique [0002] In soft soil areas, circular shields are often used for underground engineering construction. With the continuous improvement of people's traffic requirements for underground roads and rail transit, and in order to improve the space utilization rate of the tunnel section, reduce the covering soil of the shield tunnel, and reduce the construction risk, the rectangular shield tunnel technology has been gradually studied in depth. Due to the different cross-sectional forms of the rectangular shield tunnel, the internal force distribution of the segment structure is quite different from that of the circular shield tunnel, and the conventional segment joint form cannot meet the segment connection requirements. [0003] Therefo...
