GDS ENVIRO-SEWERAGE DRAINAGE MODULE & ASSEMBLY FIELD

[0001] The present invention relates to a unique, recyclable, greener, enviro-friendly modular drainage assembly for constructing the sewage conduit, in particular, but not exclusively, the invention relates to an underground modular drainage assembly for transporting faecal sludge/Industrial sludge of viscous nature or for storing the same.

BACKGROUND

[0002] Various sewage drainage systems exist which employ channels, gutters and drains for directing/storing faecal/industrial sludge. Most conventional drainage systems employ concrete pipes, vitrified clay pipes or metal components. Such concrete, clay and metal systems, however, tend to be relatively expensive to manufacture and laborious to transport & assemble. To address these drawbacks of concrete and metal drainage systems attempts have been made to develop drainage components made of plastic materials. The use of plastic drainage components has, however, in the past been restricted due to the inability to support load/gaseous pressure of relative high magnitude.

OBJECT

[0003] It is an object of the present invention to provide an alternative modular sewage drainage assembly and various associated sewage drainage units that address or at least ameliorate one or more of the above problems associated with conventional drainage systems. The present invention of the plastic modular sewage modules are able to withstand relatively high gaseous pressure generated by the sludge due to its unique way of coupling the modules together and enclosing it with interlock-able stone slabs (Fig.10:1); thus this present invention is quite unique and NOVEL in its design. Also the present invention is quite affordable in comparison with concrete or vitrified clay pipes which are used as drainage conduits often. It is also an object of the invention to provide an alternative conduit assembly which is superior than existing expensive concrete/Vitrified clay pipes for transporting/storing sludge at an affordable price.

DESCRIPTION OF PREFERRED EMBODIMENTS

[0036] Figure 1 shows an embodiment sewage drainage unit/s, assembled with bends (Fig.1) and clip locks (Fig.5/Fig.1:6/Fig.9.1/Fig.9.2) without the stone tiles (Fig.10.1) & geo-textile enveloping (Fig.10.2). The drainage unit is adapted to be used with a plurality of other similar drainage units to construct an underground modular drainage assembly (Fig.1) for transporting a viscous substance, in this instance faecal/or industrial sludge. The constructed drainage assembly (Fig.1) will be enclosed within a non-porous geo-textile (Fig.10.2) to prevent leakage of the transported viscous sludge. The embodiment sewage drainage unit comprises an assemblable support structure (Fig.1.1/Fig.6) and two load bearing members (Fig.1.2/Fig.2)on both ends. An individual load bearing member is shown in Figure 2.

[0037] The embodiment support structure (assembled by side plates (Fig.1.1/Fig.6) is squarical and longitudinally extends between a first end and a second end. The support structure (assembled by lateral side plates (Fig.1.1/Fig.6) comprises two opposing lateral support members and two opposing transverse support members. The lateral support members (Fig.6) are all of identical configuration. A free standing lateral load bearing member is shown in Figure 2. The load bearing end cap member (Fig.1.2/Fig.2) defines an ellipsoidal inner passage for transporting the viscous substance.

[0038] The sewage drainage unit comprises two load bearing members (Fig.1.2/Fig.2) held in a face-to-face arrangement within the inner passage of the support structure (assembled by side plates (Fig.1.1/Fig.6). The load bearing end cap members (Fig.1.2/Fig.2) are located respectively at the first and second ends of the support structure.

[0039] Referring to Figures 1 and 2, each support member (Fig.1.1/Fig.6) of the support structure includes a load bearing member (Fig.1.2/Fig.2) attachment formation on both ends.

[0040] The embodiment load bearing end cap member (Fig.1.2/Fig.2) attachment formation comprises a central Quadra-sided ellipsoidal cavity and the support structure attachment formation comprises a plurality of protrusions at connecting edges. The rectangular &

cylindrical protrusions of the support structure attachment formation are adapted to be received by the cavities of the load bearing member attachment formation. In this embodiment the cavities and protrusions engage by the protrusions clipping into position (snap-locking) within the cavities.

[0041] Referring to Figure 2, the load bearing member (Fig.1.2/Fig.2) framework comprises a plurality of load bearing rib cells with a curvy, ellipsoidal flowing aperture to ameliorate the smooth flow of viscous sludge.

[0042] The load bearing member framework (Fig.1.2/Fig.2) and the support member framework (assembled by Fig.1.1/Fig.6) each further comprise load bearing members (Fig.1.2/Fig.2) at both ends.

[0043] As shown in Figures 2 and 6, both the load bearing members (Fig.1.2/Fig.2) and the support members (Fig.1.1/Fig.6) include round holes and slots. The purpose of the holes and slots are to facilitate ease of inter-locking the lateral plates with load bearing plates (Fig.1.2/Fig.2) on both the ends. The connectors serve to provide added strength for the connection between the load bearing members (Fig.1.2/Fig.2) and their associated support members. Once the drainage compartments (fig.3) are connected and inter-locked, coupled with clip locks (Fig.5/Fig.1.6/Fig.9.1/Fig.9.2) a chemical glue is applied to fuse the plates together to make the drainage units integrally robust.

[0044] The support structure (Assembled by Fig.1.1/Fig.6) and load bearing members (Fig.1.2/Fig.2) are produced by an injection moulding process wherein a plastics material, in this embodiment polypropylene or similar material is formed to the desired shapes. It will, however, be appreciated that a range of materials could be employed to produce an embodiment drainage unit/s.

[0045] Figure 3 shows embodiment of sewage drainage units. The sewage drainage unit is cube shaped or rectangular and includes a support structure (Assembled by Fig.1.1/Fig.6) having opposing lateral support members and opposing transverse support members. The drainage unit further includes two face-to-face opposed load bearing end capmembers (Fig.1.2/Fig.2) and inter-connector plate (Fig.3) between the load bearing end caps (Fig.1.2/Fig.2). Each load bearing member (Fig.1.2/Fig.2) defines a Quadra-sided ellipsoidal flow aperture. As shown, the load bearing members (Fig.1.2/Fig.2) are adapted to be configured relative to adjacent load support members so that their respective flow apertures align to form a flow passage.

[0046] Figure 1 shows a modular sewage drainage assembly comprising a plurality of drainage units, here the drainage unit of Figure 3, aligned longitudinally side-by-side to transport

viscous substance with corner bend units assembled. The drainage assembly (as shown Fig.1) is in fluid communication with a storage area constructed in concrete & closed with lockable

concrete lid to be air-tight. Chemical gluey compound is applied on all plastic joints which in

turn fuse the joints together to prevent any gas leakage. The drainage assembly (Fig.1) and all conduits are enclosed within a non-porous geotextile & chemical glue is applied wherever pragmatic to fuse the plastic surfaces together to deter further leakage.

The entire sewage drainage unit throughout is tightly enclosed within inter-locking stone tiles (Fig.10.1) as shown in Fig.10 to withstand high pressures generated from the fumes of the

sludge.
