Problems solved by technology

When a single shield tunnel is too long, excavation from one side will face the problems of low excavation efficiency and long construction period. Therefore, it is necessary to set up a working shaft in the middle of the shield tunnel. However, if you want to arrange a working shaft for shield construction on the road, you will face problems Relocation and traffic diversion of a large number of underground pipelines

Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] like figure 1 As shown, this embodiment discloses a shield underground docking structure, which includes two shield machines 1 that drive oppositely at both ends of the same excavation line, and the opposite surfaces of the two shield machines 1 are provided with radially expandable The cutterheads 2 and the opposite sides of the two radially retractable cutterheads 2 (the opposite sides are located inside the shield machine 1) are connected with a driving part 3, and the driving part 3 can be a hydraulic motor.

[0039] The inner surface of the shield casing of one shield machine 1 is provided with an insertion ring c...

Abstract

The invention discloses a shield underground butt-jointing structure. Inserting ring chambers (5) are arranged on the inner surface of a shield shell of a shield tunneling machine (1), first sealing pieces (6) are arranged at the front ends of the inserting ring chambers (5), inserting rings (7) are arranged in the inserting ring chambers (5), and the tail ends of the inserting rings (7) are connected with jacks (8); and receiving ring chambers (9) corresponding to the inserting ring chambers (5) are arranged on the inner surface of a shield shell of another shield tunneling machine (1), and second sealing pieces (10) are arranged in the receiving ring chambers (9). The invention further discloses a construction method of the shield underground butt-jointing structure. According to the shield underground butt-jointing structure and the construction method of the shield underground butt-jointing structure, no working well needs to be arranged, butt-jointing sites are not affected by the ground, the geology and underground pipelines, the construction is carried out under the protection of the steel inserting rings, the construction operation can be carried out safely and reliably, the construction cost is greatly saved, and the construction period is greatly shortened.

Description

technical field [0001] The invention relates to a shield structure and a construction method, in particular to a shield underground docking structure and a construction method, and belongs to the technical field of shield construction. Background technique [0002] Shield tunnels are often laid along the roads in cities, but the ground traffic conditions on urban roads are complex and underground pipelines are dense. At present, shield tunneling is developing in the direction of long-distance and large-depth. When a single shield tunnel is too long, excavation from one side will face the problems of low excavation efficiency and long construction period. Therefore, it is necessary to set up a working shaft in the middle of the shield tunnel. However, if you want to arrange a working shaft for shield construction on the road, you will face problems Relocation of a large number of underground pipelines and traffic diversion work. For this reason, the present invention provid...
