Abstract

A guide system for a drainage rod comprises a tapered end section 6 attached to a curved bend section, wherein in use the tapered end section securely fits into the bore of a blocked drainage or sewerage pipe so that drainage rod can be inserted through the guide system into the blocked pipe. The bend section can be in the form of a 'Y' section of pipe with one of the arms of the 'Y' forming a ventilation pipe 5. An adjustable securing arm 1 is provided to push the tapered section 6 securely into the bore and to retain it in position. The guide system may also include a flexible joint 3 to assist in adjusting the guide system and a four-way cross clamp 2 may be provided to secure the guide system at the opening of the manhole or inspection chamber leading to the blocked pipe.

Description

Drainage Safe Clearing System (Rodding Guide)

Background

This Invention relates to a guide for rodding blocked drainage pipes. Which is both safer and with less mess.

When unbiocking drainage pipes, it is the normal practice to use drainage rods.

Flexible lengths of plastic fibre that are screwed together to form one long continuous rod, for dislodging blockages in drainage.

When a manhole is blocked and full of excrement, a person must either rod from above the full manhole or find the next adjoining chamber after the blockage and rod up the pipe towards the blockage.

Rodding the full chamber is difficult and messy, as once you have located the pipe at the bottom of the manhole and inserted the rod, then using an up and down momentum to force the rod down the pipe and dislodge the blockageand so allowing the drain to flow freely again. The rods being able to flex through a degree angle,tend to bend and distaught not allowing the full force to be trannsfered up the pipe.

The more usual method is to descend into the adjoining manhole being empty, to allow a person to exert more force, by using a horizontal movement with the rod, rather than the verticle up and down method from above the chamber.

This method is much more dangerous as a person descending into a manhole must check for and be aware of Methane gas, which is ever present in used foul drainage. Also once the blockage is dislodged the effluent is usually under pressure and flows quickly,not allowing much time for a person to ascend.

Statement of Invention

To overcome these problems the Rodding Guide' directs the verticle force exerted onto the rod, turning the momentum gradually into a horizontal one along the blocked pipe thus dislodging the blockage more quickly.

The Rodding Guide' is a 4" plastic pipe Similar to the pipes being used in todays drainage construction. It is tapered at one end allowing easy insertion into the blocked pipe,usually being of 4" to 6" in diameter. The pipe then splits at a junction where one section gradually turns through a radious of 90 degrees, the other carrying on in a straight line to form the vent for the blockage to pass through after being dislodged. The pipe ends after the 90 degree radius to allow extenton sections to be added to the required length of the chamber.

This allows a person to safely rod the blocked pipe from above ground, making it safer and easier to rod in manhoes.

Claims

Claims 1) A rodding guide system to assist in the unblocking of

drainage pipes,the drainage pipe being located at the bottom of a manhole/inspection chamber, the system having a flange at the beginning as to insert into the blocked pipe.

2) A rodding guide as in claim 1, having extention sections to extend the length of the system to the desired height just above or below the manhole opening.

3) A rodding guide as in claim 1, having an adjustable securing arm to push the flange securely into the blocked pipe and keep it in position,the arm having a hook attachment to assist in lowering the device into the chamber and to also disengage the arm.

4) A rodding guide as in claim 1, where the extention sectons have attachable handles making the system easier to handle.

5) A rodding guide as in claim 1, where the flanged section is attched to y' section of pipe with one end gradually radiused through 90 degrees, the other securring a detatchable rubber or plastic bung or cap.

6) A rodding guide as in claim 1, having an optional flexible joint to attach after the radius to assist in adjusting the angle of the attached extention sections.

7) A rodding guide as in claim 1, having an attachable 4 way cross clamp which is adjustable as to secure the extended system at the opening to the chamber.

8) A rodding guide as in claim 1, the flanged section being detatchable and also to be in two sizes 4" & 6" ,to fit the two sizes of drainage pipe.

Amendments to the claims have been filed as follows: Claims 1) "A rodding guide system" comprises of a tapered end attached to a bend section, wherin use,the tapered section securely fits into the bore of a blocked drainage pipe so that a flexible rod can be inserted through the guide system, into the blocked pipe.

2) "A rodding guide system" as in claim 1, having extension sections to extend the length of the system to the desired height just above or below the manhole opening.

3) A rodding guide system as in claim 1, having an adjustable securing arm to push the tapered section securely into the blocked pipe and keep it in position, the arm having a hook attachment to assist in lowering thedevice into the chamber and to also disengage the arm.

4) A rodding guide system as in claim 2, where the extension sectons have attachable handles making the system easier to handle.

5) A rodding guide system as in claim 1, where the tapered section is attached to tail of a Y-section with one extension of the Y-section beng gradually radiused through 90 degrees and a detatchable rubber or plastic bung or cap being attached to the other extension.

6) A rodding guide system as in claim 5 when dependant on claim 2, having an optional flexible joint to attach after the radius to assist in adjusting the angle of the attached extension sections.

7) A rodding guide system as in claim 1, having an attachable 4 way cross clamp which is adjustable as to secure the extended system at the opening to the chamber.

8) A rodding guide system as in claim 1, the tapered section being detatchable and also to be in two sizes 4"(lOOmm) & 6"(l5Omm) ,to fit the two sizes of drainage pipe.
