Embodiment 1

[0051] Such as Figure 1-2 As shown, it is a preferred embodiment of the pipeline wall-penetrating waterproof device and its construction process, and the heat-insulating pipe assembled with the waterproof device of the present invention. The pipeline wall-penetrating waterproof device includes a steel part main body 1, a sealing rubber ring 4, and a movable retaining ring 5 , waterproof rubber strip 8, support bracket 9 and some bolt blade assemblies.

[0052] Such as image 3 As shown, the steel part main body 1 is fixedly arranged in the inspection well wall 2, the steel part main body 1 includes a main body pipe 11 and at least two layers of steel rings 12, the inside of the main body pipe 11 is sleeved with a pipe 3, and The main pipe 11 protrudes from the wall 2 at least toward one end of the inspection well, and the main pipe 11 protrudes from the wall 2 toward the inspection well and along the main pipe 11 . 11 circumferentially distributed with some pin holes. An a...

Embodiment 2

[0068] In this embodiment, the waterproof device for pipeline penetration includes a steel body 1 , a sealing rubber ring 4 , a movable retaining ring 5 and several bolt blade assemblies. The specific structures of the steel body 1 , the sealing rubber ring 4 , the movable retaining ring 5 and several bolt blade assemblies are the same as those in the first embodiment.

[0069] The construction process of the pipeline wall penetrating waterproof device in this embodiment includes the following steps:

[0070] ① Fix the steel part main body 1 on the inspection well wall 2 and lay the pipeline 3, so that the end of the main body pipe 11 of the steel part main body 1 with a pin hole is placed in the inspection well indoor.

[0071] Specifically, in this step, the steel ring 12 of the steel body 1 is first welded to the steel bar of the wall 2, and then the manhole is poured, and the pipeline 3 is inserted into the main pipe. 11.

[0072] ② Set the sealing rubber ring 4 and the...

Abstract

The invention relates to a pipe through-wall waterproof device, a construction technology of the pipe through-wall waterproof device and a heat-insulation pipe with the pipe through-wall waterproof device. The pipe through-wall waterproof device comprises a steel piece body (1), a sealing rubber ring (4), a movable check ring (5), water stopping adhesive tape (8), a supporting bracket (9) and a plurality of bolt barging sheet assemblies, grooves (610) are molded in the sides, back to a main body pipe (11) of first barging sheets (61) of the bolt barging sheet assemblies, the parts, located outside the main body pipe (11), of second barging sheets (62) of the bolt barging sheet assemblies are provided with hook-shaped parts (620), the hook-shaped parts (620) are clamped into the grooves (610), and the grooves (610) prevent the hook-shaped parts (620) from moving in the tangential direction of the main body pipe (11). According to the pipe through-wall waterproof device, the construction technology of the pipe through-wall waterproof device and the heat-insulation pipe with the pipe through-wall waterproof device, the waterproof effect is good, the service life is long, and the delivery-receiving acceptance and use requirements can be met.

Description

technical field [0001] The invention belongs to the technical field of prefabricated heat-insulating pipes passing through walls, and in particular relates to a waterproof device for pipes passing through walls, a construction process thereof, and a heat-insulating pipe equipped with the waterproof device. Background technique [0002] During the construction of prefabricated insulated pipes and pipelines, it is usually encountered that the pipeline passes through the wall. When the groundwater level is high, the groundwater is easy to seep through the wall through the inspection well and other inspection wells equipped with compensators, valves and other equipment, causing inspection. The equipment in the well is damaged, so the waterproofing of the position where the pipeline passes through the wall is very important. [0003] Usually, in order to meet the waterproof requirements, a rigid waterproof device is installed outside the wall-penetrating pipe. The common practice...
