Definitions

  • the present invention relates to a drainage system according to the preamble of claim 1.
  • the invention comprises a kerb system that includes an integral drain, and in another embodiment the invention comprises a drainage system that is configured to be located alongside a kerb.
  • the invention relates to a composite lightweight combined kerb drainage system formed of a containment shell with a concrete infill.
  • the present invention also relates to a method of installing a drainage system according to the preamble of claim 11.
  • the kerb drainage system is composed of a lightweight outer kerb-shaped thin shell unit, housing a drainage conduit with drainage openings on the kerb face connected to the drainage conduit inside the shell to form a kerb drainage system.
  • the kerb drainage system is composed of a lightweight outer thin drain shell unit, housing a drainage conduit with drainage openings connected to the drainage conduit inside the shell to form a kerb drainage system.
  • the shell unit is designed to be filled with concrete on site to form a combined kerb drainage system. This can also be configured in a similar way to form a road drainage channel.
  • Current drainage kerbs consist of a solid kerb-shaped structure with an internal void and holes on the carriageway face of the kerb connecting onto the internal void to convey drainage runoff from the carriageway. They are either precast or factory made, and are designed to be installed on site as manufactured by butting each unit against the other on a bed of concrete. They are mainly manufactured from concrete, polymer concrete or polymers as short units (1.2m long) designed to be butted against each other to form a continuous void within the kerb to convey drainage runoff to outfall units. The outfall units collect runoff from the kerb units to the highway drainage system.
  • FR2644098 describes a method of manufacturing a drainage kerb. Formwork is used to mould the drainage kerb. The formwork is removed after moulding has been completed and before the moulded drainage kerb is installed beside a carriageway. Similar manufacturing methods are described in FR2729162 and CN106671248 .
  • LT- Kerb units are light to install as only the drainage kerb shell is initially installed on a concrete bed and filled with concrete after installation.
  • Polymer drainage kerb units although light have raised concerns regarding their performance in high impact environments. There have also been concerns of extensive damage to polymer kerb units in accidental high temperature fires say after flammable liquid spills on carriageways.
  • the LT- kerb is lightweight and easy to install, and due to its concrete component can withstand high impacts and temperatures with only cosmetic damage, the same as conventional concrete kerbs.
  • Road drainage systems are designed to be watertight to convey highway drainage effluent without leakage.
  • the drainage effluent contains contaminants such as oils, brake dust and road dusts, which have the potential to cause ground and water pollution making any leakage in a drainage system undesirable.
  • the current concrete, polymer concrete and polymer kerbs are designed to be butted against each other to form a continuous void from one drainage outfall point to another.
  • the butt joints sometimes receive sealants but it is difficult to make them fully watertight. Sometimes, water ingress in the joints leads to freezing and thawing in the colder months causing the joints to slightly open up, resulting in some undesirable leakage.
  • the LT-Kerb addresses this problem by providing a continuous conduit inside the kerb shell that extends from one outfall point to another.
  • the conduit units can be joined together like normal drainage pipes before placement into the kerb shell and then infilling with concrete. They can undergo an air-test to ensure no leakages before concrete infill.
  • the conduit unit is flexible and can be lifted off the kerb shell for assembly and testing.
  • the conduit can also be removed altogether to create a solid kerb without a drainage function. This is not possible with current kerb drainage systems.
  • Drainage kerbs have drainage holes set at a fixed height from the top of the kerb and are installed with a constant kerb face (the distance from top of road surface to top of kerb). There are some instances where it is desirable to have a variable kerb face due to obstacles or existing road and footway levels. Drainage kerbs are not suitable for this application. In such instances, the kerbs are supplemented by concrete channels and gullies. A road channel with a drainage function (referred to herein as an LT-Drain) can also be used and removes need for gullies.
  • LT-Drain A road channel with a drainage function
  • the LT-Drain channel is similar to the LT-Kerb and is composed of a lightweight outer channel-shaped thin shell unit, housing a drainage conduit with inlets at the top of channel connected to the drainage conduit inside the shell to form a drainage channel.
  • the unit is designed to be filled with concrete on site to form a drainage channel to be installed alongside highway kerbs.
  • the light shell is installed first and then filled with concrete once installed.
  • the LT-Drain channel can also complement the LT-Kerb where the areas to be drained are large. There is currently no lightweight highway drainage channel in the market.
  • a drainage system comprising a combination of a kerb drainage system and a carriageway that has a carriageway surface, the kerb drainage system comprising:
  • the internal conduit shell includes a conduit connection socket, which is configured to allow the conduit shell to be joined end-to-end with another conduit shell to form a continuous drainage channel.
  • the at least one infill opening is provided in the top wall.
  • the elongate shell structure comprises plastic moulding kerb drainage system.
  • the infill material is a cement-based material.
  • the drainage system comprises a lower portion that is embedded in a foundation material below the carriageway surface, and an upper portion that extends above carriageway surface to provide a kerb.
  • the upper portion includes the drainage opening in a side portion thereof, which is connected by said at least one drainage pipe to the internal conduit shell, to provide a fluid flow passageway that enables fluid to flow from an exterior region into the internal drainage conduit.
  • the drainage system comprises a lower portion that is embedded in a foundation material below the carriageway surface, and an upper surface that is located substantially level with the carriageway surface.
  • the upper surface includes the drainage opening connected by said at least one drainage pipe to the internal conduit shell, to provide a fluid flow passageway that enables fluid to flow from an exterior region into the internal drainage conduit.
  • a drainage system comprising a combination of a carriageway that has a carriageway surface and a kerb drainage system, the method comprising:

  • the outer shell 5 can be pigmented, texturized or printed to suit the application environment.
  • the outer shell 5 includes an internal support structure 18 for supporting an internal conduit shell 20 within the void 12.

  • Drainage openings 22 are provided in the inner sidewall 6a, which faces the carriageway when the LT-Kerb has been installed.
  • the drainage openings 22 are connected by drainage pipes 24 to drainage sockets 26 provided in the conduit shell 20, allowing water to flow from the carriageway, through the drainage pipes and into the conduit shell 20, which provides a drainage conduit 34.
