The floor slab 1 has a floor slab top surface 11, and a groove 12 formed on the floor slab top surface 11. More specifically, in the present embodiment, the floor slab 1 includes a concrete layer 101 and a waterproof body 102 formed on the concrete layer. Also, the waterproof body 102 in this embodiment has a primer layer formed on the concrete layer 101 and a top coat layer formed on the primer layer (the primer layer and the top coat layer are not shown in the drawings), and the floor top surface 11 is the top surface of the top coat layer, but not limited thereto. In the present embodiment, the material of the concrete layer 101 of the floor slab 1 is, for example, high-strength concrete (PSI, abbreviated as "round-force per Square inc") with a compressive strength of 4000PSI, but is not limited thereto. In addition, in the present embodiment, the thickness of the floor slab 1 is, for example, 25 cm, the depth of the groove 12 is, for example, 10 cm, and the shape of the groove 12 is substantially a rectangular parallelepiped. However, in other embodiments, the thickness of the floor slab 1 is not limited to the embodiment, and the depth of the groove 12 may be between 10 cm and 20 cm and is less than or equal to half of the thickness of the floor slab 1, and the shape of the groove 12 may be implemented in other shapes or irregular shapes, but is not limited to the embodiment.

Referring to fig. 3, the filling body 2 is filled in the groove 12 of the floor slab 1 and has a filling body top surface 21, and the filling body top surface 21 is as high as the floor slab top surface 11 of the floor slab 1. More specifically, in the present embodiment, the material of the filling body 2 is another concrete different from the material of the floor slab 1, and may be, for example, a low-strength concrete with a compressive strength of 1000PSI to 2000PSI for easy removal in a common construction manner, but not limited thereto. It should be noted that, the floor top surface 11 and the filling body top surface 21 are suitable for further forming a floor layer 4 made of a floor material, such as ceramic tiles or marble, but not limited thereto.

Referring to fig. 2, 3 and 4, the drainage unit 3 includes a drainage reservoir 31 and a pipe assembly 32 connected to the drainage reservoir 31.

The above is a description of the first embodiment of the drainage system of the present invention.

The drainage system of the present invention also has a second embodiment, and the difference between the second embodiment and the first embodiment will be described below.

Referring to fig. 3, in the first embodiment, the total top surface 311 of the drainage total 31 is equal to the top surface of the concrete layer 101. However, referring to fig. 5, in the second embodiment, the top surface 311 of the drainage reservoir 31 is slightly lower than the top surface of the concrete layer 101 (i.e., the boundary between the concrete layer 101 and the waterproof body 102), and, in the second embodiment, the filling body 2 defines a drainage channel shaped to fit the top surface 311 and communicating with the top inlet hole 312 (shown in fig. 4) of the drainage reservoir 31, and the drainage channel communicates with the shower outlet formed in the floor layer 4, for example, to allow sewage from the floor layer 4 to flow into the top inlet hole 312 of the drainage reservoir 31 through itself.

The drainage system of the present invention also has a third embodiment, and the difference between the third embodiment and the second embodiment will be described below.

Referring to fig. 6 and 7, in the third embodiment, the drainage system further includes the floor layer 4 (shown in fig. 6) formed on the floor top surface 11 and the filler top surface 21, and the material of the floor layer 4 may be, but not limited to, a floor material such as ceramic tiles or marble. Furthermore, the drainage channel 201 is defined by the filler 2 and the floor layer 4 cooperating together in the third embodiment. Also, the drainage unit 3 further includes an extension piece 37 disposed in the drainage channel 201 and connected to the drainage manifold 31, in other words, the drainage channel 201 serves as an installation space for installing the extension piece 37 in the third embodiment. The extension member 37 is generally tubular and defines an extension channel 371 in communication with the top inlet hole 312 (shown in fig. 4) of the drain reservoir 31, whereby sewage from the floor 4 can flow into the drain reservoir 31 through the extension channel 371.

In summary, by embedding a part of the drainage reservoir 31 and the pipe assembly 32 in the filling body 2, if the drainage unit 3 leaks water, the drainage unit 3 can be repaired by removing the filling body 2 without constructing from the bottom to the top of the water leaking floor, so that the inconvenience of the prior art can be completely overcome by the drainage system. In addition, the floor slab 1 is used as a part of an upstairs floor and a part of a downstairs ceiling, and the depth of the groove 12 is less than or equal to half of the thickness of the floor slab 1, so that when a constructor maintains the drainage unit 3, the constructor only carries out construction on the upper half part of the floor slab 1, and therefore, the influence on the use of downstairs users can be further avoided, and the aim of the invention can be really achieved.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
