Mobile Toilet Bottom Reinforcement

Mobile toilet bottom reinforcement can be achieved through the following methods, which should be implemented scientifically based on site conditions and structural characteristics:

1. Site Selection and Foundation Pre-treatment
Before reinforcement, it is essential to evaluate the site conditions first. If the ground is soft soil (such as grassland or sandy land), it is necessary to lay crushed stones or steel plates in advance, with a recommended thickness of 10-15 centimeters, to disperse pressure and enhance load-bearing capacity. For hard ground, check whether the support feet at the bottom of the toilet are intact, ensuring there is no rust or deformation to avoid structural tilting due to uneven support. Additionally, avoid low-lying areas prone to water accumulation to prevent ground softening caused by rainwater immersion.

2. Ground Anchor Fixation Method
This method is suitable for hard ground or scenarios requiring long-term fixation. At the four corners and central load-bearing positions of the toilet, use expansion screws or ground anchor pins with a diameter of no less than 12 millimeters to connect the fixing chains (straps) to the ground. If the site permits, concrete blocks (recommended dimensions: 40cm×40cm×50cm) or weight blocks (such as cast iron blocks) can be poured or placed at the bottom to enhance pull-out resistance by increasing the contact area. The depth of the ground anchors should exceed 30 centimeters to ensure resistance against pulling forces generated by wind or human collisions.

3. Additional Weight Scheme
For temporary sites or situations where ground excavation is not possible, reinforcement can be achieved by increasing gravitational balance. Distribute heavy objects such as sandbags and water tanks evenly inside or outside the toilet:

• Sandbag Configuration: Place 2-4 sandbags weighing 20 kilograms on each side, adjusting the total weight according to the toilet area (generally no less than 50 kilograms per square meter);
• Water Tank Scheme: Water tanks filled with clean water can replace sandbags, but ensure the tanks are securely fixed to prevent shaking.
  The weights should be symmetrically distributed to avoid structural instability caused by excessive weight on one side. Regularly check whether the weights have shifted or leaked.

4. Combination of Foundation Fixation and Weight Distribution
For large mobile public toilets, a combination of multiple methods should be employed. Before leasing, select a flat area without strong wind exposure, lay crushed stones or steel plates on the ground, and then install fixed weights (such as sandbags or water bags) at the bottom. Place at least 4-6 sandbags on each side, adjusting the weight according to the size of the public toilet to ensure the total weight can resist wind forces and dynamic loads during use. Additionally, weld additional support frames at the bottom of the toilet and fix them to the ground with bolts to further enhance stability.

Precautions: After reinforcement, regularly check whether the fixing components are loose and whether the weights have shifted, especially after heavy rain or strong winds. If ground settlement or structural tilting is detected, immediately cease use and conduct reinforcement again.
