Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.

As shown in fig. 1 and 2, the prefabricated toilet caisson provided by the present embodiment includes a caisson, a first drainage pipe 1, a second drainage pipe 2, a leak-discharging pipe 3, a horizontal drainage pipe 4, and a downstream tee 5.

The first drainage vertical pipe 1 is embedded at the bottom of the caisson 100, and the first drainage vertical pipe 1 is in contact with the caisson 100 through a drainage trap 3 embedded in the outer diameter of the first drainage vertical pipe.

The horizontal drainage pipe 4 and the second drainage vertical pipe 2 are communicated with the first drainage vertical pipe 1 through the downstream tee joint 5. The horizontal drainage pipe 4 is a toilet drainage pipe, sewage of the horizontal drainage pipe 4 is discharged into the first drainage vertical pipe 1, and the second drainage pipe 2 is a toilet drainage pipe of the previous floor.
