How to Remove the Inner Wall of a Mobile Toilet

The removal of the inner wall of a mobile toilet requires selecting an appropriate method based on the wall type. The core steps include assessment and preparation, step-by-step removal, safety protection, and post-removal handling. The specific operations are as follows:

I. Assessment and Preparation

1. Confirm the wall type: Identify the wall material (such as brick-concrete structure, lightweight partition wall, light steel keel gypsum board wall, etc.). Different materials require corresponding tools. For example, a brick-concrete structure requires hammers and crowbars, while a lightweight partition wall may require an electric drill to dismantle the keels.
2. Check load-bearing capacity: It is strictly prohibited to remove load-bearing walls, as this may damage the overall structural stability of the toilet. You can determine this by observing the wall thickness, location (such as being connected to the main building structure), or consulting professionals.
3. Mark hidden facilities: After turning off the main water and electricity valves, use a detector to locate the positions of water pipes and electrical wires to avoid damaging them during removal, which could lead to water leakage or electrical shock.
4. Prepare tools and protective gear: Equip yourself with tools such as wrenches, screwdrivers, utility knives, crowbars, hammers, and electric drills according to the wall type, and wear protective gear such as gloves, goggles, and dust masks.

II. Step-by-Step Removal Operations

1. Non-load-bearing partition walls: Start from the top of the wall and use a crowbar and hammer to knock off the blocks one by one. Avoid violently pushing down the wall to prevent damage to adjacent structures (such as the ground waterproof layer or adjacent walls).
2. Lightweight partition walls or gypsum board walls:
   • If fixed with light steel keels, use an electric drill to dismantle the keel brackets.
   • If fixed with air nails/staples, first use a utility knife to clean the sealant at the joints, and then separate the cabinet from the wall to prevent the board from tearing.
3. Brick-concrete structure walls: Use a hammer and crowbar to gradually remove the wall, controlling the force to prevent the wall from suddenly collapsing. At the same time, pay attention to protecting the ground waterproof layer.
4. Wall attachments: First, dismantle the sanitary ware (such as toilets and washbasins), and then knock off the tiles. When knocking off the tiles, tap gently to avoid damaging the underlying waterproof layer. If the waterproof layer is damaged, it needs to be reapplied.

III. Safety and Protection

1. Construction protection: Maintain ventilation during the removal process and wear protective gear to avoid inhaling dust or being injured by flying debris.
2. Pipe protection: Use cloth balls or plugs to block the floor drains and sewer pipe openings to prevent debris from clogging the pipes.
3. Force control: Avoid using excessive force or inappropriate tools (such as directly cutting a brick wall with a circular saw) to prevent accidental damage to the structure.

IV. Post-Removal Handling

1. Garbage cleanup: Classify and dispose of the construction waste at designated stacking points to avoid mixing it with household waste.
2. Hidden hazard inspection: Check the removal area for any remaining pipes or structural hazards (such as unremoved keels or exposed wires) to ensure nothing is overlooked.

Precautions: If the removal involves changing the sewage discharge pipes or temporarily cutting off the water supply, you need to apply for a permit from the administrative department in accordance with the law to avoid illegal operations.
