Tunnel lining with segmental rings behind TBMs are reinforced concrete elements and must be calculated and designed according to the standards of reinforced concrete constructions. In tunnelling, however, specific circumstances must be taken in account, which make design much more complicated: The determination of loads during ring erection, advance of the TBM, earth pressure and bedding of the articulated ring, is difficult. The ring model and the design input values must be studied carefully according to the parameters of the surrounding soil.

Floor paint is ideal for environments where hygiene and durability are critical, such as the floors of food processing plants, pharmaceutical factories, laboratories, equipment rooms, and areas requiring anti-corrosion, wear-resistance, and chemical resistance—like underground parking lots, factory warehouses (especially those with forklift traffic), and industrial zones. Choosing the right type of floor coating can significantly improve performance, longevity, and cost-effectiveness.
If you're looking to select the appropriate flooring solution for your space, it's essential to consider several key factors. Here’s a detailed guide to help you make an informed decision:
First, evaluate the mechanical performance requirements of the floor. These include:
1. **Wear Resistance**: What kind of traffic will the floor be exposed to? Will there be heavy foot traffic, forklifts, or rolling equipment? This determines how durable the coating needs to be.
2. **Pressure Resistance**: How much weight will the floor support? High-traffic or heavy-load areas require stronger, more resilient coatings.
3. **Impact Resistance**: Will the floor be subject to drops, impacts, or sudden pressure changes? A coating that can withstand such forces is crucial in industrial settings.
Next, consider the chemical performance requirements:
1. **Acid and Alkali Resistance**: What types of chemicals will be used in the environment? The concentration and frequency of exposure affect the choice of coating material.
2. **Solvent Resistance**: Will the floor come into contact with solvents or cleaning agents? Understanding the type and duration of contact helps in selecting the right protective layer.
Then, assess the floor's location and condition:
- Is it an **underground** or **ground-level** floor? Underground areas may require moisture-resistant solutions, while ground-level floors might need different treatments based on humidity levels.
- Evaluate the **substrate condition**:
- **Strength**: The base should have a minimum compressive strength of 20 MPa to ensure proper adhesion.
- **Flatness**: If the surface is uneven, you may need to apply epoxy mortar to level it before applying the coating.
Aesthetic considerations also play a role:
- **Color Preferences**: Do you want a specific color scheme or branding?
- **Finish Type**: Choose between matte, semi-gloss, or high-gloss finishes based on visual appeal and maintenance needs.
- **Surface Smoothness**: Some applications require a very smooth finish for aesthetics or functionality.
In certain environments, additional features like **fire resistance** or **anti-static properties** may be necessary, especially in cleanrooms, laboratories, or data centers.
Finally, always take your **budget** into account. Different floor coatings vary in cost and thickness, so choosing the right one depends on both your financial constraints and long-term needs.
Also, **safety** is a top priority. In oily areas, ramps, or wet environments, non-slip flooring is essential to prevent accidents and ensure a safe working environment.
By carefully evaluating these factors, you can make a well-informed decision that meets both functional and aesthetic needs while ensuring long-term value and performance.
