Anyang Mobile Toilet Construction Plan

The construction plan for mobile toilets in Anyang should be implemented scientifically in stages, combining the installation of septic tanks, the construction of the toilet body, and general installation specifications, as detailed below:

I. Septic Tank Connection and Installation

1. Preliminary Preparation:
   • Site Selection: Choose an area with higher elevation and smooth drainage, avoiding regions with dense underground pipelines. After confirming the installation location, communicate with the property management or relevant departments to clarify surrounding environmental restrictions.
   • Tools and Materials: Prepare tools such as shovels, tape measures, and wrenches. Check that the specifications of PVC pipes, elbows, and sealing rings match. If construction occurs in winter, prepare insulation cotton in advance.
2. Excavation and Positioning:
   • Determine the excavation depth based on the mobile toilet model (usually about 1.2 meters), with a diameter 20 centimeters larger than the septic tank body. Lay a 10-centimeter-thick gravel bed at the bottom and compact it to ensure a stable foundation.
   • Use a level to calibrate the height of the septic tank's inlet and outlet, aligning them with ground pipes to prevent future drainage issues.
3. Pipe Connection:
   • Align the PVC pipes with the septic tank's inlet and outlet, seal them with sealing rings, and then fix the interfaces with glue. Install an anti-backflow valve at the connection point to prevent sewage backflow.
   • Secure the pipe direction with concrete or bricks, ensuring a reasonable slope (usually not less than 2%) for easy drainage.
4. Backfilling and Commissioning:
   • Backfill gravel in layers up to 5 centimeters above the pipes, then compact with yellow soil in layers. Open the inlet valve to observe if the drainage is smooth and empty any impurities in the tank before first use.
   • Maintenance Points: Regularly check the pipe's tightness, wrap insulation cotton in winter to prevent freezing, and ensure compliance with local environmental emission standards.

II. Toilet Body Construction

1. Material Standards:
   • Select corrosion-resistant and aging-resistant environmentally friendly materials (such as stainless steel and high-density polyethylene) to ensure structural stability. Use C25 concrete for ground hardening with a thickness of not less than 15 centimeters to prevent settlement.
2. Construction Process:
   • Assemble the toilet frame according to the design drawings, ensuring tight connections between components. Pay attention to the tightness when installing doors and windows to prevent odor diffusion.
   • Securely fix internal facilities (such as toilets and sinks) and conceal water and electricity lines to avoid exposure.

III. General Installation Specifications

1. Project Overview:
   • Clearly define the scope of the construction area, topography, and hydrogeological parameters (such as an underground water level depth of about 1.5 meters) and develop targeted measures.
2. Compilation Basis:
   • Follow project contracts, bidding documents, construction drawings, and national standards (such as GB50300-2013 and GB50345-2010) to ensure compliance.
3. Construction Management:
   • Establish positions such as project manager and technical leader, clarifying the construction period (e.g., the installation period for the public toilet on X Street is from X/X/X to X/X/X), quality (meeting national standards), and safety goals (no safety accidents).
   • Conduct technical briefings for workers and ensure that measurement and staking accuracy meet specification requirements.

Strict adherence to standards can ensure that the service life of mobile toilets exceeds 30 years, avoiding abandonment due to improper construction.
