Embodiment 1

[0031] Example 1, such as Figure 1~3 As shown, a pipe jacking machine without disassembly and assembly pipeline system includes a shield body 40, a pipe joint 402, a pushing device 6, a pipeline retracting device 20 and a guide device 30, and the pushing device 6 pushes the pipe joint 402 and the shield body 40 Moving forward, the pipeline retractable device 20 is wound with a pipeline 201, the pipeline retractable device 20 is used for retracting the pipeline 201, the outer wall of the shield body 40 is provided with a shield wire groove 401, and the outer wall of the pipe joint 402 The pipe section wire groove 403 is arranged on the top, and the pipe section wire groove 403 is connected with the shield body wire groove 401. The pipeline 201 passes through the guide device 30 and extends into the shield body 40 through the pipe section wire groove 403 and the shield body wire groove 401. The guide device 30 is used for the pipeline to orientate into the pipe section wire gro...

Embodiment 2

[0034] Example 2, such as Figure 4~5 As shown, a pipeline system without disassembly and assembly of a pipe jacking machine, the seal 50 includes an elastic sealing water-stop ring 501 arranged between the shield body 40 and the pipe joint 402, which is used for sealing and waterproofing, and the shield body Both the wire groove 401 and the pipe section wire groove 403 are provided with a wire groove cover plate 504, and the shield body wire groove 401 and the pipe joint wire groove 403 are equipped with cover plate sealing strips 505 symmetrically up and down, and the wire groove cover plate 504 is connected with the cover plate The sealing strip 505 is a sealing fit. The wire channel cover plate 504 is pasted on the outer edges of the pipe section wire channel 403 and the shield body wire channel 401 by an adhesive, and is used for sealing the pipe section wire channel 403 and the shield body wire channel 401 .

[0035] further, such as Figure 8~9 As shown, the shield wi...

Embodiment 3

[0038]Embodiment 3, a pipeline system without disassembly and assembly of a pipe jacking machine, a construction method of a pipeline system without disassembly and assembly of a pipe jacking machine, including the following steps: S1: Paste a cover plate with an adhesive in the wire channel 401 of the shield body and seal it The strip 505 and the lower sealing rubber block 503 install the pipeline joint 404 in the shield wire groove 401; the pipeline joint 404 is welded on the shield body 40 for fixing the pipeline 201 in the trapezoidal groove 401 of the shield body and the shield body 40 of the shield machine , to prevent falling off;

[0039] S2: Paste the cover plate sealing strip 505 and the lower sealing rubber block 503 with an adhesive in the pipe joint wire channel 403, and paste the elastic sealing water stop ring 501 on the pipe joint 402. This step can be implemented after the pipe joint 402 is prefabricated , that is, this process is completed before hoisting, an...

Abstract

The invention discloses a pipeline system without disassembly and assembly of a pipe jacking machine and a construction method thereof, which solves the problems in the prior art that pipe jacking construction requires frequent disassembly and assembly of pipelines and low construction efficiency. The invention includes a shield body, a pipe joint and a pushing device. The pushing device pushes the pipe joint and the shield body to move forward. It also includes a pipeline retracting device and a guiding device. The pipeline winding device is wound with a pipeline. The outer wall of the shield body There is a shield wire groove on the top, and a pipe joint wire groove is arranged on the outer wall of the pipe joint. The pipeline passes through the guide device and extends into the shield body through the pipe joint wire groove and the shield body wire groove. There are seals in both. Compared with the current pipe jacking method construction, the present invention can carry out continuous construction without dismantling the pipeline during the jacking process, shorten the construction period, improve work efficiency, and has great engineering advantages, and the pipe jacking machine does not need to disassemble the pipeline system And its construction method saves cost and improves construction safety factor.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a pipe jacking machine disassembly-free pipeline system and a construction method thereof. Background technique [0002] The pipe jacking technology is to use the hydraulic cylinder to jack the pipe jacking machine and the pipe joints to be laid underground one by one from the pipe jacking working well without excavating the surface until the trenchless underground pipe laying in the pipe jacking receiving well construction technology. The pipe jacking machine has gradually become the "new darling" of urban underground space development due to its simple excavation construction process, high hole formation rate, and environmental protection. The significant social benefits of pipelines are suitable for construction under shallow covering soil and narrow spaces, and have obvious technical advantages. etc. have broad application space and market prospects. [0003] D...
