Description

Bridge cut-off heat-insulating waterproof ware

Technical Field

The utility model belongs to the technical field of heat supply pipelines, and particularly relates to a broken bridge heat insulation type waterproof device.

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.

The existing waterproof device is characterized in that a corrugated pipe is positioned outside an inspection well, one end of the corrugated pipe is fixed on the waterproof device in a sealing mode, the other end of the corrugated pipe is fixed on a wall penetrating pipe in a sealing mode, the outer side of the corrugated pipe contacts with underground water, and the underground water is prevented from penetrating into the inspection well. In the long-term use process, the corrugated pipe is often corroded and 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.

In addition, when the waterproof device is used for urban heating, hot water is conveyed in the working tube of the waterproof device; the bellows adopts stainless steel, and the intraductal heat of work can pass through the work pipe and transmit the bellows for the intraductal fluidic heat of work is conducted away, causes the loss of heat.
