Earthquake-resistant joints for maintenance hatch

Polyethylene cushioning material
Fastening band(SUS304)(We conclude this pipe.)

Butyl rubber adhesive
Extended bands crimp against the drilledcross-section and absorb the non-land of the drilledcross-section to achieve high water tightness.

Certiﬁcation No. 1641
This product has been certiﬁed
and certiﬁed by the New
Sewerage Technology Promotion
Organization based on theGuidelines for Implementation ofConstruction Technology
Certiﬁcation Projects (SewerageTechnology).

Expansion jig
insertion slotStopper(Blue) is the proper stopper if the standard drilling
diameter is used.
Main rubber
Rubber and shapes that are diﬃcult to deform at thewater pressure level normally assumed are adopted.

These level 2 earthquake-resistant joints have proven outstanding earthquake resistance, water cut-off, and workability.

● Shortening of construction period

2 minutes

It does not require a curing time and can be immediately ﬁlled back after
installation.

No glue required

Dry method● This is a fumed method that does not require adhesives.
● Excellent waterprooﬁng and earthquake resistance○ Waterprooﬁng(External water pressure 0.1MPa / Internal water pressure0.05MPa)○ Bending angle : 15
○ Displacement in the direction perpendicular to the tube axis : 20mm
○ Displacement in the axial direction of the tube : 60mm
○ Earthquake resistance(External water pressure 0.1MPa / Internal water pressure 0.05MPa)○ Bending angle of 1 and shifting in the direction of the pipe axis : 60mm

Position thison the left.
Conﬁrm whether thebore is standard.
If the standard is set,use (blue) for theappropriate stopper.

Clean the drilledsection with a cloth.
Repair smoothsurfaces for cracks,chipping, or shortage.

Peel oﬀ so that theprotective ﬁlm on thedrilled cross section
side is not left fromthe inside of thecylindrical part.

Turn the cylinder overand push it into themaintenance hatch.

Rubberprojections

Firmly press the projection of the body rubber
against the expansion band to position theexpansion band.Then set the appropriate
stopper to the stopper stop.

Replace the inverted
cylinder and attach
the fastening band.
(The above is thework of the factory.)

After inserting andpositioning the pipe,
remove theprotective ﬁlm.
(From here on, this is
the work at the site.)

14 Supportingbar

To prevent
deformation of thepipe mouth, ﬁll thelateral clearance withquick-setting cement
at least 5cm.Also,
insert a support bar
until ﬁnishing work.

12 Barr Corp.
Insert the expansion jig into the jig insertion
slot and tilt it slightly to the right toward thedrilling center.
Doing so will make it diﬃcult for the anti-slip
bracket to ﬂoat.

or moreOperate the hydraulic pump and expand it
while observing the hydraulic gauge until thestopper enters.(※)
When the stopper is turned on, release theoil pressure and remove the jig.

※ If the hydraulic pressure drops below 7Mpa, insert a larger
stopper.
（If the red stop does not rise to 7Mpa, the bore size is too large.）

PVC pipe is a ﬂexible pipe, so the pipe opening may be transformed by soil pressure.
This is because there is a gap between the maintenance hatch drilling diameter and thePVC pipe in the lateral direction, and this should be remedied before backﬁlling.

When the position isdetermined, attach apolyethylene
cushioning material
from the inside of themaintenance hatchand ﬁx it with shrimp,etc.

Quick-setting
cementPrecautions
Plant● If you expand too far, be aware of product failures and safety issues.（Do not increase the hydraulic pressure above 12 Mpa.）
Site● Secure the pipe with crushed stone sacs to prevent the pipe from sinking. Use protective equipment (gloves, etc.) to ensure safety.
