Description
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.
Background
Buried manholes are an important component of a buried pipe network system, and are generally provided with control valves, instruments, meters and the like for different purposes. Control valves, instruments, meters and the like in the inspection well are technical problems which are difficult to solve for a long time due to corrosion and damage of groundwater and surface water.
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.

In the long-term use process, the corrugated pipe is frequently leaked. Under the condition, the waterproof device needs to be replaced or the well wall of the inspection well needs to be excavated, so that the construction amount is large, and the treatment period is long.
The waterproof device is provided with a working pipe, a heat preservation layer sleeved outside the working pipe and a heat preservation sleeve sleeved outside the heat preservation layer, the corrugated pipe is fixed on the outer side of the heat preservation sleeve in a sealing mode, and the structural strength of the heat preservation pipe is not large, so that the fixing between the corrugated pipe and the heat preservation pipe is often not sealed, the corrugated pipe is waterproof and invalid, and underground water is led to permeate into an inspection well.
