Shuozhou Mobile Toilet Installation

The installation of mobile toilets in Shuozhou must adhere to strict technical specifications and procedures, covering four major stages: construction preparation, foundation construction, main structure installation, and leasing services. Here are the specific key points:

I. Technical Key Points for Construction Preparation

1. Site Survey and Planning: Ensure that the foundation ground elevation difference is ≤5mm and the slope is ≤1%, using a level for calibration. The geological bearing capacity must be ≥80kPa, and weak soil layers should be replaced with graded sand and gravel (compacted in layers with a thickness of ≥300mm and a compaction coefficient of ≥0.93). The surrounding environment should be kept at least 5m away from high-voltage lines and 1.5m away from underground pipelines, with prior communication with the property owners for disclosure.
2. Material Acceptance Standards: The steel structure frame should be made of Q235B material with a wall thickness of ≥3mm and a zinc coating of ≥80μm. The sandwich panel should be 50mm thick (rock wool bulk density of 120kg/m³) with a fire rating of Class A. Sanitary ware should have a ceramic water absorption rate of ≤0.5%, and hardware should have a corrosion resistance rating of ≥Grade 5. Water supply and drainage pipes should be UPVC with a wall thickness of ≥2.8mm, and sealant should comply with GB/T 14683.
3. Machinery and Safety Configuration: The main machinery includes an 8t truck crane, a 3t forklift, and a ZX7-400 electric welder, among others. Measuring tools should include a total station (accuracy of 2mm+2ppm) and a DS3-level level. Safety equipment should comply with GB 2811-2019, including safety helmets, double-hook safety harnesses, and temporary distribution boxes with three-level distribution and two-level protection.

II. Foundation Construction Specifications

1. Concrete Foundation: Use a C30 concrete strip foundation (cross-section of 300mm×400mm) with longitudinal reinforcement of Φ12@150 and transverse reinforcement of Φ8@200, and a cover thickness of ≥40mm. The formwork joint gap should be ≤2mm, the concrete slump should be 180±20mm, the vibration time should be 15-30s per point, and curing should last for ≥7 days with a strength of 75% before installing the main structure.
2. Embedded Part Installation: Use a 200mm×200mm×10mm steel plate with four M16 expansion bolts (embedded depth of ≥100mm), with an axis deviation of ≤5mm and an elevation deviation of ≤3mm. The exposed parts should be painted with epoxy zinc-rich primer (≥60μm) + chlorinated rubber topcoat (≥40μm).

III. Main Structure Installation Process
The steel structure frame should be connected using 8.8-grade M16 high-strength bolts with a torque value of 45-50N·m and a friction surface slip coefficient of ≥0.45. The frame perpendicularity should meet the accuracy requirement for column heights of ≤6m to ensure structural stability.

IV. Leasing and Installation Services
In the Shuozhou area, mobile toilets can be leased through companies such as Shanghai Changjiu Environmental Protection Technology Co., Ltd. The services include demand assessment, site survey, equipment transportation, installation and commissioning, cleaning and sewage container replacement, equipment recovery, and disinfection throughout the entire process, with users not bearing transportation or installation costs.
