Embodiment Construction

[0022] Please refer to the attached Figure 6 As shown, the present invention is a large-diameter single-hole double-track subway tunnel, which consists of a tunnel body 1, a bottom plate 2, a middle partition wall 3, a track bed plate 4, a track 5, an evacuation platform 6, a line pipeline 7, and a catenary 8, etc. It consists of several parts.

[0023] Wherein, the outer diameter of the tunnel body 1 is 10m, and the inner diameter is 9m.

[0024] The bottom plate 2 is poured at the bottom of the tunnel body 1 . The partition wall 3 is poured vertically on the base plate 2 .

[0025] The track bed slab 4 is horizontally arranged on the partition wall 3 and inside the tunnel body 1, and it is a cast-in-place reinforced concrete structure.

[0026] Described track 5 is provided with two, and it is laid on the track bed plate 4. The evacuation platform 6 is connected to the ballast bed plate 6 and is located between the two rails 5 . The evacuation platform 6 is a prefabric...

Abstract

The invention relates to a large-diameter single-hole double-line subway tunnel and a construction method thereof. The large-diameter single-hole double-line subway tunnel comprises a tunnel body, a bottom plate, middle partition walls, a track bed plate, tracks, an evacuation platform, line pipelines and contact nets. The bottom plate is poured at the bottom of the tunnel body; the middle partition walls are vertically poured on the bottom plate; the track bed plate is horizontally arranged on the middle partition walls inside the tunnel body; the two tracks are arranged and laid on the trackbed plate; the evacuation platform is connected to the track bed plate and is located between the two tracks; the line pipelines are laid on the side wall of the tunnel body; the contact nets are installed on the top of the tunnel body and located over the tracks. According to the large-diameter single-hole double-line subway tunnel, uplink and downlink trains are arranged in the same tunnel to reduce the occupation of the underground space by about half, the construction is convenient, and costs are reduced.

Description

【Technical field】 [0001] The invention relates to a tunnel and a construction method thereof, in particular to a large-diameter single-hole double-track subway tunnel and a construction method thereof, belonging to the technical field of subway construction engineering. 【Background technique】 [0002] At present, only one subway train can be arranged in a shield tunnel with a conventional diameter, and the up and down trains of the subway need to be realized by two shield tunnels, and the distance between the two shield tunnels is at least 1 times that of Dongjing. Therefore, the subway section of the conventional shield tunnel occupies a large underground space, and it is extremely difficult to arrange the subway section of the conventional shield tunnel for the condition of narrow underground space. [0003] Therefore, in order to solve the above-mentioned technical problems, it is necessary to provide an innovative large-diameter single-hole double-track subway tunnel and...
