Brick Mobile Toilet Construction Method

There is no direct reference plan for brick mobile toilets, but the method of transforming discarded tiles into movable toilets can be used for reference to achieve similar functions through structural modifications. The specific steps are as follows:

1. Base Structure Cutting and Adaptation
Select large-sized discarded tiles (it is recommended that the thickness be ≥1.2cm) as the base. Place the toilet flat on the tile surface, and use a ruler to mark the outline along the bottom edge of the toilet. When marking, reserve an installation allowance of 2-3cm. Use an angle grinder to cut the tile along the marked line to form a rectangular base that is slightly larger than the bottom of the toilet. Maintain straight-line precision during cutting to avoid edge damage that could affect structural stability.

2. Installation of Mobile Components
Turn the cut tile over (with the smooth side facing down) and install universal wheels symmetrically at the four corners. Prioritize heavy-duty universal wheels with brakes (with a load-bearing capacity of ≥100kg) to ensure stability during movement. Mark the positions of the screw holes on the back of the tile with a marker pen. Use an electric drill (equipped with a tile-specific drill bit) to drill holes. The hole diameter should match the diameter of the screw rods. Insert M6 or M8 screw rods, screw the nuts onto the screw rods from the front of the tile to fix the universal wheels, and finally use an angle grinder to cut off the protruding parts of the screw rods on the back of the tile to keep the surface flat.

3. Connection of the Sewage Discharge System
Place the toilet back on the tile base, mark the position along the edge of the toilet's sewage outlet, and drill a hole from the back of the tile through to the front sewage outlet. Insert a flexible sewage discharge pipe (it is recommended to use a PVC reinforced pipe), and wrap the interface with waterproof tape to prevent leakage. The other end of the sewage discharge pipe needs to be connected to a fixed drainage pipe. A sealing ring should be installed at the interface and secured with pipe clamps. It is important to note: The movable structure may cause uneven stress at the connection of the sewage discharge pipe, so regular inspection of the tightness is required.

4. Fixation and Installation of Accessories
Apply white waterproof cement (it is recommended to use polymer-modified cement) along the bottom edge of the toilet, press the toilet to the marked line position, and keep it level for 24 hours until the cement cures. When installing the water tank, ensure that the water inlet pipe is tightly connected, and fix accessories such as the toilet lid in the conventional way. Key point: Do not move the structure during the cement curing period, as this may cause the bonding to fail.

5. Functional Testing
After the installation is completed, a leakage test is required: Fill the water tank to the maximum water level, flush the toilet continuously 3 times, and check for leakage at the connection between the tile base and the sewage discharge pipe. During the movement test, gently push the structure to observe whether the universal wheels rotate smoothly and whether the brake device is effective.

Precautions:

• This plan is suitable for temporary or low-frequency use scenarios. For long-term use, the load-bearing fatigue problem of the tile base needs to be considered.
• The length of the sewage discharge pipe is recommended to be controlled within 1.5 meters. Excessive length can easily lead to poor drainage or pipe detachment.
• Avoid uneven ground surfaces when moving to prevent the tile base from breaking.
