Abstract
The utility model discloses a kind of sealing structures of the circumferential seam of underground pipe gallery, the sealing structure makes circumferential flange using angle steel, and it is punched on the vertical flanging of angle steel, and 2-section pipe corridor is connected across this some holes by fastening bolt, circumferential gasket seal is set between joint face, angle steel is parallel on another flanging of piping lane axis and is provided with axial seal gasket, the axial seal gasket is covered on the flanging parallel with axis of two different piping lanes, and it is compressed using pressing plate, pressing plate is bolted on flanging, pressing plate compresses longitudinal sealing gasket, so that axial seal gasket, which is pressed on flanging, plays sealing function.When leakage or gasket seal failure occur for the sealing structure of the utility model, axial seal gasket can be removed and be replaced, ensure that the antiseep service life of seam crossing reaches 100 years.
Description
Technical field
The utility model is related to a kind of sealing structure, the sealing knot of the circumferential seam of especially a kind of underground pipe gallery
Structure.
Background technology
The joint seal of underground pipe gallery is usually to use rubber pad, but being averaged for piping lane is not achieved in the service life of rubber pad
Service life, the applicant have been devoted to the research and application of Underground Steel pipe gallery, as shown in Figure 1, having disclosed
In patent, the circumferential sealing between piping lane is welded with stainless steel electrode, in order to ensure sealing means 100 years
Life requirements, but cost is very high, it is high to the skill set requirements of construction personnel.If using rubber pad, rubber pad must be in the later stage
It can be replaced in maintenance process.
Utility model content
Purpose of utility model：The utility model provides a kind of sealing structure of the circumferential seam of underground pipe gallery, should
Structure can effectively seal the circumferential seam of piping lane junction, and can when sealing rubber pad fails dismounting and change caulking gum
Pad ensures 100 years service life.
Utility model content：The utility model provides a kind of sealing structure of the circumferential seam of underground pipe gallery, including
Circumferential gasket seal, axial seal gasket, pressing plate, bolt, circumferential gasket seal are set to the 2-section pipe corridor of circumferential seam crossing
Between the vertical flanging of angle steel flange, angle steel flange circumferential direction is weldingly fixed on piping lane, angle steel flange and circumferential gasket seal
On offer bolt hole, bolt passes through bolt hole that angle steel flange is connect compression with circumferential gasket seal, thus by two
Section piping lane is connected and fixed and seals；Angle steel flange is parallel to above two axial flangings of piping lane axis and is provided with axial gasket
Piece, pressing plate are pressed in axial gasket on piece, offer bolt hole on pressing plate and axial flanging, bolt will across bolt hole
Pressing plate is connect with axial flanging, to compress axial seal gasket.
Its center platen can be an integral molding structure, and the shape of pressing plate is identical as the axial circumferential shape of flanging；Pressing plate
It can be decomposed into multiple, pressing plate circumferentially can equidistantly be uniformly distributed two or more and be pressed on axial seal gasket
On axial flanging.
Wherein, pressing plate axial length is more than axial seal gasket axial length, and axially axis is being completely covered in pressing plate when installation
To gasket seal.
Advantageous effect：The utility model can easily solve the Seepage problems of piping lane circumferential direction seam, and each component is removable
The technology requirement unloaded replacement, therefore the sealing structure antiseep service life of seam crossing can be made to reach 100 years；Using the side of dual-seal
Formula so that sealing effect is more preferable.
