Mobile Toilet Floor Drainage Design
The following plans can be referred to for the floor drainage design of mobile toilets, and they should be selected or combined according to actual needs:
1. Sunken bathroom design
This plan achieves a hidden layout by embedding drainage pipes into the backfilled cement layer while improving drainage efficiency. Its core advantage lies in supporting a secondary drainage system: if the ground waterproof layer is damaged and causes water seepage, the accumulated water can automatically drain into the sewer through the secondary drainage outlet, preventing long-term soaking from causing structural damage. In addition, after the pipes are wrapped in the cement layer, the drainage noise is significantly reduced, making it suitable for scenarios with high requirements for quietness. During construction, attention should be paid to controlling the slope of the backfilled layer (usually 1%-2%) to ensure that the water flows smoothly and converges to the main drainage outlet.
2. Wall-mounted drainage system
The drainage pipes are arranged along the wall and connected to the drainage riser from the wall surface, with no exposed pipes on the ground. This design keeps the ground flat and reduces sanitary dead corners, making it especially suitable for mobile toilets that require flexible adjustment of the positions of sanitary ware. For example, equipment such as washbasins and toilets can be moved freely along the wall without being restricted by the position of the ground drainage outlet. However, attention should be paid to construction accuracy: the pipe connections need to be tightly sealed to avoid leakage; during later maintenance, the wall needs to be damaged, so it is recommended to reserve inspection ports or adopt a modular pipe design.
3. Ground slope and water diversion design
In the shower area, the marble grooving process is used, and the water is guided to the drainage outlet through a slope of 1%-3%, with the middle area remaining flat. The grooved surface can be designed with anti-slip textures to take into account both drainage and safety. This plan avoids the abruptness of traditional sloping ground and improves user comfort. If space allows, a water diversion trough can be set around the drainage outlet to further accelerate the drainage speed and prevent water accumulation.
4. Toilet relocation solutions
If the position of the toilet needs to be adjusted, a special relocator can be used for short-distance (≤10cm) relocation, but it should be noted that the pipe slope must not be less than 2% to avoid blockage. For long-distance relocation, two plans are recommended: one is to use a wall-mounted toilet, with the drainage pipes arranged along the wall surface, and the relocation distance is unlimited, but the cost is relatively high; the other is to raise the ground to form a slope and realize drainage by embedding pipes, but this will reduce the net height of the toilet, and the space utilization rate needs to be weighed.
Plan combination suggestions: The sunken design combined with the wall-mounted system can take into account efficient drainage, quietness, and flexible space utilization; the shower area adopts a slope + grooving design, and the toilet area selects a relocator or a wall-mounted plan according to the relocation needs to form a complete drainage system. Before construction, a comprehensive evaluation should be carried out according to the size of the toilet, the frequency of use, and the budget to ensure the feasibility of the plan.
