Zhongxian Mobile Toilet Booth Installation

The installation of mobile toilet booths in Zhongxian requires following key steps such as positioning and line-setting, foundation construction, and component assembly and fixation to ensure installation accuracy and structural stability.

I. Positioning and Line-Setting & Foundation Construction

1. Positioning and Line-Setting
   Before installation, determine the error range of control points according to planning requirements (the error should not exceed one-thousandth). Use a theodolite to measure the overall planar position, and then use a steel tape to recheck the planar dimensions and bay distances. This step directly affects the accuracy of the main project, so it is necessary to ensure that the positioning lines are completely consistent with the planning drawings.

2. Foundation Construction

   • Excavation Preparation: Calculate the excavation depth and slope according to the foundation plan. After determining the edge line positions, use a level to transfer the elevation to the leveling stakes or axis stakes and mark them.
   • Foundation Pit Treatment: After excavation, check the width and strength of the pit bottom to ensure they meet the design requirements. Transfer the axis and elevation to the bottom of the foundation pit, and mark the foundation plan dimensions and ground beam positions on the cushion to provide a reference for subsequent structural installation.

II. Component Assembly and Fixation

1. Tool Preparation
   After receiving the goods, prepare tools such as an electric drill, a 4.2-millimeter drill bit, and a rivet gun to ensure an efficient assembly process and firm connections.

2. Assembly Process

   • Inner Corner Installation: Install the inner corner components of the booth first to ensure the initial formation of the structural framework.
   • Panel Assembly: Insert the panels into the slots and align them. Check whether the edges of the upper and lower panels are flush to avoid misalignment affecting overall stability.
   • Drilling and Fixation: Use a 4.2-millimeter drill bit to drill holes at the assembly points, insert rivets, and then reinforce them with a rivet gun to ensure uniform load-bearing at the connection points.

III. Key Precautions

1. Accuracy Control: Strictly recheck the data during the positioning and line-setting stage to avoid main body deviation caused by control point errors. Monitor the elevation and axis in real-time during foundation construction to prevent foundation pit dimension deviations.
2. Structural Stability: Ensure that the panel slots are fully embedded during assembly, and the rivet fixation spacing is uniform (usually not exceeding 20 centimeters) to avoid deformation caused by excessive local stress.
3. Safety Regulations: Wear protective equipment when operating electric drills and rivet guns. Set up warning signs after foundation pit excavation to prevent personnel from falling.

By following the above steps, the installation of mobile toilet booths in Zhongxian can be systematically completed, balancing efficiency and quality to meet the long-term use requirements of environmentally friendly public toilets.
