BACKGROUND

[0002] Modular integrated buildings are a high-level form of development in the field of fabricated buildings, in which various components are prefabricated into modules in a factory and then transported to the construction site for assembly.

[0003] Due to the multiple construction procedures and the requirement for reliable waterproofing, the bathroom is the most complex construction unit in building construction. In order to improve construction efficiency and quality, the bathroom unit is integrated with the module to complete the procedures such as integrated construction of sanitary fixtures, floor waterproofing, and wall and floor tile integration in the factory, which is a way to improve the quality and speed of bathroom construction, with the advantages of fast construction speed, low labor intensity, and resource saving.

[0004] When the bathroom is a squat toilet, in order to reduce the height of the squat toilet step and the structural slab height required for filling the squat toilet, in order to reduce the weight of the bathroom module and facilitate transportation and hoisting, cross-floor drainage is an effective way to achieve this purpose.

[0005] However, in modular integrated buildings, the bathroom is prefabricated with the module in the factory. In order to avoid damage to the pre-buried squat toilet drainage pipeline during transportation and hoisting, the drainage pipeline should not protrude from the module bottom plate when pre-buried. Such a setting greatly inconveniences the connection of the cross-floor drainage pipeline.
