Tongchuan Mobile Toilet Construction

The construction of mobile toilets in Tongchuan requires a systematic approach across multiple stages, including project planning, preparation, material selection, foundation work, and main structure installation, to ensure the achievement of quality, safety, and environmental protection goals.

1. Project Overview and Construction Objectives
The project is located at the intersection of the city's core commercial district and transportation hub, covering a total area of 150 square meters. It plans to construct three standalone mobile restrooms, equipped with water supply and drainage, electricity, and ventilation systems. The construction objectives are clear: quality must comply with national acceptance standards, aiming for a municipal-level high-quality project; the total construction period is 60 calendar days; achieving a safety goal of 'zero casualties and zero accidents'; ensuring construction noise, dust, and sewage discharge meet standards, with a building waste recycling rate exceeding 90%.

2. Construction Preparation Stage

• Technical Preparation: Organize technical personnel to familiarize themselves with the drawings, prepare construction organization designs and special plans, calibrate measuring instruments, and collect local meteorological and geological data.
• Site Preparation: Complete the erection of fencing around the construction area, level the site, build access roads, set up temporary office areas and material warehouses, and connect water and electricity supplies.
• Resource Preparation: Assign management personnel such as project managers and technical leaders, as well as labor personnel including carpenters and electricians; prepare machinery such as excavators, loaders, and concrete mixers.

3. Material Inspection and Storage

• Inspection Standards: Steel materials must be accompanied by a material certificate, with each batch subjected to ultrasonic flaw detection sampling, achieving a 100% pass rate; panels must be inspected for thickness tolerance, coating adhesion, and fire rating; biodegradable bacteria agents require a detection report from the provincial environmental protection department.
• Storage Requirements: Steel materials should be stored off the ground (≥30cm above the ground, covered with waterproof cloth); panels should be stacked to a height of ≤1.5m, with underlying wooden spacers at intervals of ≤60cm; electronic equipment should be stored in an environment with a temperature range of 5-35°C, humidity ≤70%, and away from strong magnetic fields.

4. Foundation Construction Techniques

• Site Treatment: Determine the bearing capacity, replace collapsible loess with lime-soil, and set up drainage slopes and ditches.
• Foundation Pouring: Use C30 concrete, equipped with anti-crack steel mesh; pre-embedded parts should use Q235 steel plates and be hot-dip galvanized; cover and cure for ≥7 days after pouring.

5. Main Structure Installation

• Frame Assembly: Use full-house scaffolding for support, connect with high-strength bolts, with a verticality deviation of ≤H/1000 (and ≤15mm), and a planar axis deviation within ±5mm.
• Module Splicing: Use lifting equipment, with lifting points set according to specifications to ensure splicing accuracy.

6. Characteristics of Mobile Toilets
Mobile toilets offer advantages such as high mobility, environmental friendliness, small footprint, unique appearance, and a short construction period (production period of 10-15 days, ready for use after on-site installation and connection to water and electricity), making them suitable for rapid deployment in high-traffic areas.
