Ningxia Mobile Environmental Toilet Construction

The construction of mobile environmental toilets in Ningxia adopts a modular design, which is prefabricated in the factory and then transported to the site for installation. The specific construction points are as follows:

I. Project Overview and Design Standards

The construction needs to clarify the applicable scenarios, such as temporary scenarios in scenic spots, construction sites, and large-scale events. Each toilet is designed according to a standard module of 3m×6m, covering an area of 20 square meters. It includes a men's restroom area, a women's restroom area, a dedicated room for the disabled, and an independent hand-washing area. The entire structure can be lifted and relocated as a whole. The design follows the 'Urban Public Toilet Design Standards', with a ratio of 5:3 for women's toilet stalls to men's toilet stalls. The barrier-free facilities comply with the requirements of the 'Barrier-Free Design Specifications'. Considering the climatic characteristics of the Ningxia region, the seismic fortification intensity is set at 8 degrees, the roof wind load resistance is ≥0.55kN/m², and the thermal insulation performance meets the requirements for normal use in extreme low-temperature environments of -25℃.

II. Construction Preparation

Technical Preparation: Organize the construction team to conduct a drawing review, focusing on solving key technologies such as low-temperature welding processes in winter in Ningxia, sealing construction techniques in windy and sandy weather, and precision control of modular lifting. Prepare a special construction plan and train welders in low-temperature welding processes. Only those who pass the assessment can take up their posts. Site Preparation: The site is leveled using a 20t road roller for compaction, with a bearing capacity requirement of ≥150kPa and a surface flatness error controlled within ±30mm. Pour a 100mm thick C20 concrete cushion and pre-embed 8 M16 anchor bolts according to the design position. The exposed length of the bolts is 200mm, and the pre-embedding position deviation is ≤10mm.

III. Construction Process

This includes site leveling, drainage facility installation, foundation construction (foundation cushion, foundation beam), structural construction (walls, roof), door and window installation, rainwater collection system installation, water supply and drainage system installation, electrical system installation, and toilet equipment installation. These steps must be carried out strictly in accordance with the construction plan and design requirements.

IV. Construction Quality Control and Safety Measures

Quality Control: Select high-quality raw materials to ensure that the material quality meets relevant national standards. Regularly inspect the construction quality during the construction process and promptly rectify any problems found. After the construction is completed, organize relevant departments to conduct an acceptance inspection to ensure that the project quality is qualified. Safety Measures: Formulate relevant safety management systems and strengthen safety management on the construction site to ensure construction safety.
