Description

Waterproof device for underground wall penetrating
Technical Field
The utility model belongs to the technical field of underground through-hole pipelines, and particularly relates to a waterproof device for an underground through-hole.

In order to prevent underground water from seeping into a well through a gap between a pipeline through hole of a well wall and a well penetrating pipeline, packing is generally adopted between the well penetrating pipeline and the through hole arranged on the well wall. However, under long-term erosion of moisture, the packing is prone to failure; and the axial movement of the well pipe caused by heat expansion and cold contraction is particularly obvious, and the axial movement of the well pipe for heat supply accelerates the sealing failure of the existing packing. After the sealing fails, the outer side of the inspection well needs to be excavated for packing replacement, so that maintenance and replacement are troublesome. Thus, a waterproof device for underground pipeline well penetration is arranged, and the outer side of the waterproof device is fixedly connected with the buried wall penetrating pipe in a sealing way through a corrugated pipe, so that underground water cannot penetrate into an inspection well.
