Problems solved by technology

At present, the length of pipeline tunnels continues to break through, and when the length of the shield tunnel is long, it is usually necessary to connect multiple pipelines in series, so the difficulty of pipeline installation is great
In addition, the number of pipelines installed in the existing oil and gas shield tunnels is usually 1 to 2. When multiple pipelines share the shield tunnel, due to the limited space in the tunnel, the construction will increase with the increase in the number of pipelines. , and when the distance of the shield tunnel is longer, the difficulty of construction is doubled, and the difficulty of maintenance work in the later period is also increased

Abstract

The invention discloses a pipeline installation device and installation method in a long-distance shield tunnel, comprising a pipeline support installed in the shield tunnel, a plurality of rails installed on the pipeline support and a plurality of Sliding support, the pipe is installed on the sliding support, and one pipe corresponds to multiple sliding supports; the pipe is transported to the shield tunnel through the sliding support, and will be transported to multiple pipeline sections in the shield tunnel After the connection is fixed, foam concrete is poured into the shield tunnel to fill it. The beneficial effect of the present invention is: by installing the track on the pipeline support, and directly transporting the pipeline to the inside of the shield tunnel for connection through the sliding support, without secondary hoisting, the stress of the welding joint of the pipeline is reduced; the construction equipment can also pass through the track Transportation, convenient for pipeline installation and construction; adopt the three-dimensional pipeline support layered up and down, through reasonable layout, multiple pipeline lines can be installed in the shield tunnel, and the space utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of oil and gas pipeline engineering, in particular to a pipeline installation device and method in a long-distance shield tunnel. Background technique [0002] Shield tunneling is one of the common ways for pipelines to pass through without excavation. As a special channel for pipelines, after the construction of shield tunneling is completed, the pipelines must be installed in the shield tunnel. Compared with ground pipelines, the installation of pipelines in shield tunnels The space is small, and the installation of pipelines is difficult. Especially in the case of multiple pipelines sharing shield tunnels, it is necessary to comprehensively consider a series of issues such as comprehensive layout of pipelines, stress safety, pipeline transportation, and installation schemes. At present, the length of pipeline tunnels continues to break through, and when the length of shield tunnels is long, it is usually ...
