Full Text	PVC Weep-hole Fitment with inverted filter box Technical field of the Invention: The present disclosure is related to a PVC Weep hold fitment with inverted filter box, wherein the proposed device is most suitable to be applied during any masonry construction, specially in solid plain concrete/reinforced concrete, brick/stone masonry, abutment, wing-wall and return walls to drive moisture from the back filling. The proposed PVC Weep-hole is preferably designed as a complete device to be fitted suitably in structural surfaces of a bridge/flyover etc. Back-ground and prior art: During any masonry construction work, certain small openings are purposefully left in the outer walls as an outlet for water and its vapors trapped/getting trapped inside that masonry structure. Such small holes in exterior wall cladding systems not only allow moisture/water to escape out, but also help in air pressure equalization in the cavity space drained by the weep-hole. The only problem is that these holes get blocked with passes of time due to excess fall down of mortar. Apart from this certain insects, rats, snacks and birds start residing in these holes, leading to blockage of the weep-hole. Therefore these weep-holes are usually filled with certain type weep-hole fitments. Modern conventional weep-holes employ weep-hole screens/fitments, which are typically constructed plastic or metallic pipes with certain covers. Still in the conventional weep-hole fitments, there are certain structural drawbacks, due to which these undergo blockage with time, mainly because of mortar falling or ingression of small animals etc. The main objective of the present invention is to propose a new weep-hole fitment, made up of PVC (poly Vinyl chloride); wherein the proposed complete device is very long lasting, completely corrosion free, free from any ingression of small animals; wherein this proposed fitment mainly comprises of perforated PVC pipe with nylon net wrapping; inverted filter box with filter media and special nylon net cover on the box; PVC Outer end-cover housing with the housing plate, PVC based weight and associated neoprene flap; PVC socket; PVC bracket; holding brackets of inverted filter box. Another objective of the invention is to propose a weep-hole fitment integrated with an inverted filter box, which is effectively capable of maintaining its normal functioning due to effective protection from any blockage due to mortar accumulation around the filter box. Statement of the Invention: The present invention is intended to propose a new weep-hole fitment with the inverted filter box, as described herein. Summary of the Invention: Proposed PVC weep-hole fitment with inverted filter box is a device developed by a unique assembly of its main components, all made up of PVC (poly Vinyl chloride). Apart from PVC made components, the proposed device also employs nylon net wrapping/covering and a neoprene rubber flap. The proposed PVC weep-hole fitment with inverted filter box mainly comprises of: (i) perforated PVC pipe with the nylon net wrapping, (ii) inverted filter box with filter media and special nylon net cover on the box, (iii) PVC Outer end-cover housing with (a) housing plate, (b) PVC based weight , (c) associated neoprene flap and (d) dome shaped perforated PVC outer cover, (iv) PVC socket, (v) PVC bracket and, (vi) holding brackets of inverted filter box. In the proposed device, there is a perforated PVC tube of suitable I.D and O.D., deciding the thickness & strength of the tube. The perforated part of the tube is properly wrapped by nylon net. At one end of this perforated PVC tube there is PVC housing cover plate, fitted properly using a PVC socket, closing that end. Inside this housing cover plate there is a circular opening with a valve arrangement. This valve is created by suitable mounting of neoprene rubber flap with a weight, preferably PVC based weight. Above the weight-neoprene flap arrangement (valve), there is a perforated PVC dome as final cover of the end. The other end of the perforated PVC pipe, covered under nylon net, is fitted inside a filter box: with the help of suitable holding brackets. Between the upper surfaces of perforated PVC pipe and inner surface of filter box there is certain type of filter media, which is preferably granules/inert material etc. Detailed description of the invention with the help of attached drawings labeled with numerical symbols is substantially done hereinafter.
