Xinzhou Outdoor Portable Toilet Installation
The installation of outdoor portable toilets in Xinzhou should follow modular design specifications and be completed through three stages: foundation engineering, structural engineering, and decoration engineering, with the core advantages of rapid deployment and low environmental impact.
I. Foundation Engineering: Ensuring Stability and Drainage Capacity
Foundation engineering is the primary step in the installation of portable toilets, directly affecting the stability of the overall structure.
- Excavation of Foundation Pit: A backhoe excavator is used to excavate a 1.2-meter-deep strip foundation, with a slope ratio of 1:0.5 designed to prevent soil collapse. A 300-millimeter manual cleaning layer is reserved at the bottom of the pit to ensure the flatness of the foundation and avoid structural deformation caused by an uneven foundation.
- Drainage System: Drainage ditches and collection wells are set up around the foundation pit, equipped with submersible pumps to remove accumulated water in real-time, preventing rainwater or groundwater from soaking the foundation and affecting the strength of the concrete.
- Concrete Pouring: C30 commercial concrete is used, with a slump controlled within 180±20 millimeters to ensure fluidity and compactness. An immersion vibrator is used for vibration to avoid quality defects such as honeycombing and pitting, enhancing the bearing capacity of the foundation.
II. Structural Engineering: Modular Assembly and Precision Control
Structural engineering adopts a lightweight steel structure modular design, combining factory prefabrication with on-site assembly to shorten the construction period.
- Steel Structure Installation: The verticality deviation of columns should be controlled within H/1000 (H is the height of the column) and ≤10 millimeters, and the levelness deviation of beams should be ≤2 millimeters per meter to ensure the overall stability of the structure. On-site, a combination of bolt connection and welding processes is used to balance strength and construction efficiency.
- Module Lifting: A 25-ton truck crane is selected, with lifting points set at the center of gravity of the structure. During lifting, guy ropes are used to control stability, preventing module tilting or collision. The gaps between modules are filled with waterproof sealant and fixed with stainless steel pressing strips to ensure waterproof performance.
III. Decoration Engineering: Focusing on Waterproofing and Durability
Decoration engineering focuses on waterproofing and durability to meet the needs of outdoor environments.
- Wall Panel Installation: Wall panels are fixed with self-tapping screws, with a spacing of ≤300 millimeters. A 50-millimeter-wide waterproof tape is pasted at the panel seams to prevent rainwater penetration. The interior walls use 15-millimeter-thick waterproof gypsum boards and are treated with waterproofing to enhance moisture resistance.
- Functional Adaptation: Portable toilets are suitable for temporary event venues, tourist attractions, and other scenarios. Their modular design allows for rapid disassembly and reassembly, reducing the long-term impact on the surrounding environment and aligning with the concept of green construction.
Conclusion: The installation of outdoor portable toilets in Xinzhou requires strict control over foundation stability, structural precision, and waterproof performance, achieving rapid deployment through modular design and balancing efficiency with environmental protection needs.
