Construction Methodology for Air Domes

Introduction

Installing an air dome is a complex process that requires careful planning and execution. This guide provides a detailed overview of the construction methodology for air domes, ensuring a secure and efficient setup.

Step-by-Step Installation Guide

1. Site Preparation

Clear the site of all obstructions and level the ground.
Prepare the surface, ensuring that it is smooth and free of sharp objects.
Lay a protective film over the entire area to prevent damage to the air dome membrane.

2. Membrane Installation

Unroll the air dome membrane and position it correctly.
Join the membrane sections using high-frequency welding technology, ensuring a secure and airtight connection.

3. Anchoring

Drill holes and install chemical anchors into a concrete ring beam around the perimeter of the dome site.
Attach L-profiles to these anchors, which will secure the membrane's bottom edge.
For steel tube anchoring, install rings into the anchoring and then install anchoring tubes through the membrane sleeve and rings.
Ensure the membrane's edges are pressed tightly against the ground, without any gaps.

4. Structural Installations

Position and secure the revolving entrance doors and emergency exits into self-supporting structures anchored to concrete pads.
Install the main ventilation and heating/cooling units, as well as any additional systems such as destratifiers or optional ventilation systems.

5. Inflation and Adjustments

Inflate the air dome gradually, monitoring for any issues or misalignments.
Adjust the membrane and ensure it is properly fitted to the anchoring system.
Check all joints and connections, ensuring they are secure and airtight.
Attach and secure all air inflation ducts and electrical components, including lighting and monitoring systems.

6. Final Checks

Conduct a thorough inspection of the entire setup, checking for proper installation of anchors, membranes, and all mechanical and electrical systems.
Verify that the air dome's pressure is maintained correctly, using the installed sensors and control systems.
Verify that air dome's temperature sensors and heating work correctly, perform burner check.
Ensure all safety features, including emergency exits and ventilation controls, are operational and accessible.

7. Operation and Maintenance

Regularly check and maintain the air dome's structure, especially after severe weather conditions.
Remove any accumulated snow from the air dome to prevent structural damage.
Perform routine inspections of the main and emergency ventilation units to ensure proper functioning and safety.

Technological Features

Double-layer Membrane: Provides superior insulation, reducing heating and cooling costs.
Automated Environmental Control: Systems manage overpressure, ventilation, and lighting to ensure optimal conditions inside the dome.
Backup Systems: Diesel-operated backup aggregates maintain operations during power outages, ensuring uninterrupted use.
