Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description will be given with reference to the accompanying drawings and preferred embodiments in order to provide the best mode, structure, features and effects according to the present invention.

Please refer to fig. 2, fig. 3 and fig. 4, the first embodiment of the present invention provides a straight-through inner insertion with two rows, which includes a connection section 1 and an inner insertion section 2, wherein a drainage hole 21 is provided in the inner insertion section 2, a plurality of fixing strips 22 are provided outside the inner insertion section 2, a drainage groove 23 is provided between the adjacent fixing strips 22, a radially extending limiting block 3 is provided at the upper end of the fixing strip 22, and a drainage groove 31 is provided between the adjacent limiting blocks 3. The water filtering groove 31 has the same width as the water discharging groove 23. The water flows through the water filtering tank 31 and the water draining tank 23 in sequence and enters a water draining pipe.

The fixing bar 22 has a guide surface 221 at a lower end thereof, and the guide surface 221 is used to facilitate the insertion of the insertion section 2 into the drain pipe. The connecting section 1 is an oval straight-through or a circular straight-through, and the connecting section 1 is used for connecting other drainage pipe fittings. The outer surface of the connecting section 1 is provided with a reinforcing rib 11 for improving the connecting strength. The interposer two rows are made of PVC. The maximum outer diameter of the fixing bar 22 is the same as the inner diameter of the drain pipe. The maximum outer diameter of the limiting block 3 is larger than the inner diameter of the drain pipe.

In the installation, insert section 2 and insert the drain pipe and make fixed strip 22 and the contact of drain pipe inner wall with interior interpolation to make stopper 3 and the contact of drain pipe upper end, at this moment, water filtering tank 31 is located between earth's surface (decorative layer) and the waterproof layer.

In the use, wash port 21 is used for normal drainage, and the water that stores up in the waterproof layer top then loops through drainage groove 31, drainage tank 23 and gets into the drain pipe, makes things convenient for the drainage, and a plurality of stopper 3 play and block cement mortar and filter the effect that other granule foreign matters got into the drain pipe.
