Technical Field
The application relates to the technical field of trenchless construction, in particular to a special anti-corrosion heat-insulation pipe for trenchless engineering.
Background
With the social progress and economic development, the usage amount of underground pipelines is increased. The traditional underground pipeline construction method needs to excavate the ground for laying, and has great influence on the environment. Pipeline laying is currently commonly performed using trenchless underground pipeline construction techniques. The trenchless underground pipeline construction technology is a construction technology for laying, repairing and replacing underground pipelines and cables under the condition that a groove is not dug in the ground. Wherein, the underground pipeline is paved mainly by using a horizontal hole forming technology or a directional drilling technology. The construction method does not damage the environment, block traffic, disturb residents and have high construction speed. However, during the construction process, if the underground condition is complicated, the pipeline is easy to lose the protective layer due to mutual friction with other pipelines or damage of construction tools. Under the condition that external wet rainwater and underground water are soaked, water enters the patch to cause the pipeline to be corroded, so that the heat insulation pipeline loses the heat insulation effect, normal operation of the pipeline is influenced, and the service life is shortened.
Therefore, the problem is solved by an anticorrosion heat-insulation pipe, when the existing anticorrosion heat-insulation pipe is used, the sealing performance of the joint of the pipeline is poor, accumulated water in the heat-insulation pipe can be caused, the service life of the heat-insulation pipe is shortened, and in addition, when rainwater passes through, the stress is large, great vibration can be generated, and the collapse of the pipeline is caused.
