Technical Field

The invention relates to a water blocking structure of an underground heat transfer pipe network.

Background

The heat supply network is a pipeline system for conveying and distributing heat supply media to heat users from a centralized heat supply source. When the heat transfer pipeline is laid underground, due to the change of media or environment in the pipeline, such as expansion and contraction caused by heat or vibration of the pipeline, the heat transfer pipeline can be displaced at the position where the heat transfer pipeline passes through the well chamber, and therefore underground water permeates into the well chamber.

The existing structure that the heat supply pipeline passes through the well chamber is that a wall penetrating pipe passes through the wall of the well chamber, the heat supply pipeline is sleeved in the wall penetrating pipe, and water is easily seeped in a gap between the heat supply pipeline and the wall penetrating pipe, so that an underground heat supply pipe network is damaged.

The waterproof glue water plugging structure of the underground heat transfer pipe well prevents underground water from permeating into a well chamber through the waterproof glue between the waterproof layer and the heat transfer pipe and the wall penetrating pipe. When the wall of the well chamber and the heat delivery pipeline generate a gap due to relative displacement, the flexible stretching of the flexible waterproof layer and the elasticity of the waterproof glue are utilized to enable the water plugging structure to elastically deform along with the displacement, so that underground water can be prevented from permeating into the well chamber, the waterproof effect is ensured, and the damage of water seepage to the interior of the well chamber is avoided.
