a bathroom floor construction with secondary drainage structure, its characterized in that: the vertical main drainage pipe comprises a caisson structure, a first waterproof layer, a backfill layer, a mortar leveling layer, a second waterproof layer and a ceramic tile layer which are sequentially paved in the caisson structure, wherein the second drainage structure is arranged in the backfill layer and comprises a second drainage collector, a drainage groove arranged in the backfill layer and a second drainage pipe connected between the second drainage collector and the vertical main drainage pipe; the drainage groove is formed in the top surface of the backfill layer, the groove is inclined downwards to the secondary drainage collector, and the width of the drainage groove is 15mm.

Further, the vertical main drain pipe is located at a corner remote from the toilet outlet.

Further, the number of the drainage grooves is five, the included angle between the first drainage groove and the fifth drainage groove is 120-130 degrees, the included angle between the first drainage groove and the fourth drainage groove is 85-90 degrees, the included angle between the first drainage groove and the third drainage groove is 60-75 degrees, and the included angle between the first drainage groove and the second drainage groove is 30-45 degrees.

Further, the first drain channel extends toward the toilet outlet.

In addition, the secondary drainage collector is of a cylindrical structure with an opening at the top surface, and the cylinder wall of the secondary drainage collector is provided with a rectangular water inlet corresponding to the drainage groove and a circular water outlet used for communicating with the secondary drainage pipe.

More preferably, the vertical main drain pipe and the secondary drain pipe are both PVC drain pipes.

Compared with the prior art, the utility model has the following characteristics and beneficial effects:

the utility model designs a secondary drainage structure, which solves the problem of water accumulation of the caisson. In the construction process of the backfill layer of the bathroom, a pipeline is arranged on the upper portion of the backfill layer for secondary drainage, so that water leaked due to the damage of the waterproof layer on the upper portion is discharged through the pipeline, and phenomena of long-term water accumulation, leakage to the lower layer and the like of the backfill layer are avoided.
