Abstract
The method, primarily for the sealing of bar-holes created when checking for gas leaks, comprises injecting into the hole a mixture of a curable resin and a resin hardener to a depth which is sufficient to enable at least a portion of the hole to be filled with the mixture and allowing the resin to cure. Preferably a foam plug is inserted into the hole at a point between either end of the hole prior to the mixture being injected, with the mixture being injected to a depth where it engages the plug. The resin is preferably an epoxy resin such as bisphenol A or AF and the hardener is preferably mercaptan, polyamine or polyaminoamide, with the amine being aliphatic. Before being mixed together, the resin and hardener are preferably held separately in a cartridge from which they are ejected under pressure and mixed in a mixing nozzle before being discharged into the hole.
Description
Improvements in Sealing a Hole The present invention relates to sealing a
hole and particularly a bar-hole.
When an underground gas pipe or main is suspected of leaking gas, a technique for detecting the leak is to drill or punch a small diameter elongate hole from above that section of the pipe or main where the leak is suspected of occurring and down through the surface of the road or pavement to terminate near the surface of the main or pipe.
The hole so formed (a so called "bar-hole") permits the leaking gas to escape from the pipe or main and be detected at the upper end of the hole by known gas detection equipment. Should no gas be detected at that particular point a further bar-hole distant from the first hole can be formed and the detection process repeated until gas is detected.
When the detection process has been completed the bar-hole or holes must be sealed to prevent any possible egress of gas from the hole under the New Road and Street Works Act 1991 (specification for the reinstatement of openings in highways Section Sl l.S test holes) . The usual method for sealing such holes is to insert into them a suitable solid plug made of say bitumen for example which then forms a sealing plug. However it has been found that the method of application is not always acceptable and accordingly it is an object of the present invention to provide a method which reduces the setting or curing time for the sealant.
According therefore to the present invention we provide a method for sealing a hole particularly a bar-hole extending downwardly from a surface of a road, pavement or the like, to a point beneath the surface, the method comprising injecting into the hole a mixture of a curable resin and a resin hardener to a depth which is sufficient to enable at least a portion of the hole to be filled with the mixture and allowing the resin to cure.
c c c c c c c c c À c c cc c c c c c c c c c c c c c c c c c c c c c c À c c cce c c c c Preferably prior to the mixture being injected into the hole a foam plug is inserted into the hole at a point between either end of the hole.
Suitably the mixture is injected to a depth sufficient for it to engage the plug.
Conveniently the resin is an epoxy resin.
Preferably the epoxy resin is bisphenol A or AF.
Suitably the hardener is a mercaptan, polyamine or polyaminoamide.
Conveniently the polyamine is an aliphatic.
In one embodiment of the invention, initially before they are mixed together the resin and hardener are held separately in a cartridge, Preferably in this case the resin and the hardener are ejected under pressure from the cartridge and are mixed together in a mixing nozzle before being discharged into the hole.
An embodiment of the invention will now be particularly described with reference to the accompanying drawing which shows a sectional view of apparatus for sealing a bar-hole in accordance with the method of the present invention.
The apparatus comprises a known-type sealant injection gun I having a body forming a cylindrical chamber 2, an elongate needle-like dispensing nozzle 3 at one end of the chamber 2 and a trigger 4 at the other end of the chamber 2.
The resin and the hardener are contained in separate compartments of a cylindrical cartridge 5. In use, the cartridge 5 is fitted into the chamber 2 as shown in the drawing.
À c c c c c c 4 c c C c ce e c c c c c C c C e c c C c À C c c C c Activation of the trigger 4 causes a pressure to be applied to the cartridge 5 which is forced towards the nozzle 3 causing the resin and hardener to mix together in the nozzle 3 and then discharge therefrom as a mixture.
In use of the apparatus, firstly the bar-hole 6 is cleared of water. Then a foam plug 7 is inserted into the bar-hole 6 to a depth of about 200mm. The plug 7 serves merely to prevent the sealant filling the entire length of the hole 6 when it is fed into the hole 6. The nozzle 3 of the injection gun 1 is then positioned over the hole 6 to be filled as shown in the drawing and the trigger 4 is slowly squeezed to cause pressure to be applied to the cartridge 5 to mix the resin and hardener together and discharge them into the hole 6 where the resin is allowed to cure.
The hole 6 is filled to the surface 8 of the road 9 to form a small dome (not shown) and sand and bauxite are added to produce an anti-surface.
The resin is an epoxy resin such as bisphenol A or AF while the hardener is a mercaptan, polyamide or polyaminoamide which can be aliphatic. ' À À À
