Description

Technical Field

[0002] Hot spring pipes are used to introduce hot spring water to the required places. Hot spring pipes are laid in an overhead or underground manner. The overhead hot spring pipes are exposed to the outside, and the heat loss in the pipes is relatively serious. In addition, they are affected by the external environment, resulting in a short service life of the hot spring pipes. In the underground laying method, the hot spring pipes are laid in the foundation pit and buried. The hot spring pipes are protected by the soil layer, which reduces the impact of the hot spring pipes on the external environment. However, in the underground laying method, the hot spring pipes are directly placed in the foundation pit. On the one hand, the hot spring pipes are unstable. On the other hand, the pipes are greatly affected by the soil environment. The water in the soil can easily soak the pipes, causing corrosion to the pipes and affecting the service life of the pipes.
