Abstract

The utility model provides a kind of waterproof short tube through walls with earrings, its effect be exactly when making the connection between plastic drain-pipe and brick manhole or steel concrete manhole one-time-concreting shaping, make the two seamless link.Tube wall apart from short tube side through walls is welded with a rubber swelling seal ring, short tube through walls with rubber swelling seal ring is cast in body of wall, both outside well, left one section, to have inserted in well one section, the short tube through walls outside reserved manhole and the HDPE pipeline welding outside manhole.Because the short tube through walls with rubber swelling seal ring is cast in body of wall, and with the HDPE pipeline welding outside manhole, with the rubber swelling seal ring water-swellable of earrings, the sewage in manhole so just can be stoped to leak outside, thus pipeline is connected with well room is closely knit, ducted sewage does not leak outside, and ducted sewage does not leak outside, thus ensures that body of groundwater is not contaminated.

Description

With the waterproof short tube through walls of earrings

Technical field

The utility model relates to the connecting tube of outdoor drainage pipe and brick manhole or steel concrete manhole, especially relates to the waterproof pipe fitting that plastic pipe is connected with manhole.

Background technology

At present, the application of environmentally-friendly plastic tubing in municipal engineering, can replace traditional concrete reinforced pipe.Plastic pipe is from heavy and light, and single-unit pipeline is long, easy transportation and installation.Plastic pipe also has good corrosion resistance, the advantages such as long service life simultaneously.But during the connection of plastic drain-pipe and brick manhole or steel concrete manhole, be generally directly plastic drain-pipe is inserted in the reserved hole of manhole, then between the gap of plastic pipe and reserving hole, pour into plain concrete.Can not vibrate owing to pouring into plain concrete between gap, its compactness can not ensure, therefore under normal circumstances, when water flowing, often leaks between the gap of plastic pipe and reserving hole, is difficult to ensure closed-water test.

Summary of the invention

The utility model, for existing above-mentioned defect, provides a kind of waterproof short tube through walls with earrings, and its effect is exactly make plastic drain-pipe and to be connected one-time-concreting between brick manhole or steel concrete manhole shaping, makes the two seamless link.

In order to solve the problem, the utility model is achieved through the following technical solutions: the waterproof short tube through walls of band earrings, comprise: short tube through walls, rubber swelling seal ring, a prefabricated short tube through walls, tube wall apart from short tube side through walls is equipped with a rubber swelling seal ring, short tube through walls with rubber swelling seal ring is cast in body of wall, outside well, both left one section, to insert in well one section, the short tube through walls outside reserved manhole and the HDPE pipeline welding outside manhole.

The beneficial effects of the utility model are: the rubber swelling seal ring water-swellable of band earrings, and the sewage in manhole so just can be stoped to leak outside, thus pipeline is connected with well room is closely knit, ducted sewage does not leak outside, thus ensure that body of groundwater is not contaminated.

Below in conjunction with embodiment and accompanying drawing, the utility model is described further.

Accompanying drawing explanation

Fig. 1 is schematic cross-sectional view of the present utility model;

Fig. 2 is I-J generalized section.

Shown in figure: 1 be concrete wall or brick wall body in well, 2 be short tube through walls, 3 be rubber swelling seal ring, 4 for inside manhole, 5 for outside manhole.

Detailed description of the invention

Make a HDPE short tube 2 through walls in advance, short tube length, at about 800mm, is being welded with a high band earrings rubber swelling seal ring 3 for 100mm, thick 20mm on the HDPE tube wall at 300mm place, short tube side.When drainage inspection well is built by laying bricks or stones, by short tube 2 through walls and rubber swelling seal ring 3 primary concreting in body of wall, and short tube through walls will go deep into about 200mm in well, at well reserved about 300mm outward.And the 300mm short tube outside reserved manhole welds with the HDPE pipeline outside manhole, thus the HDPE pipeline reaching outside manhole 5 is connected with 4 short tubes reserved inside manhole.With rubber swelling seal ring 3 water-swellable of earrings, the sewage in manhole so just can be stoped to leak outside, thus pipeline is connected with well room is closely knit, ducted sewage does not leak outside.

Claims

1. be with the waterproof short tube through walls of earrings, comprise: short tube through walls, rubber swelling seal ring, it is characterized in that: a prefabricated short tube through walls (2), tube wall apart from short tube through walls (2) side is equipped with a rubber swelling seal ring (3), short tube through walls (2) with rubber swelling seal ring (3) is cast in body of wall, both outside well, left one section, to have inserted in well one section, the short tube through walls (2) outside reserved manhole and the HDPE pipeline welding outside manhole.
