Shield tunneling mortar is a type of filling mortar specifically used for filling between subway pipe segments and underground layers during the assembly process. Its main function is to improve construction efficiency, reduce the use of on-site land, and eliminate the need to stack materials such as sand, cement, and admixtures on site; At the same time, reducing dust on site plays a role in protecting the environment.
Application scenarios:
Subway construction: In subway tunnel construction, shield mortar is used to fill the gaps between the segments, enhancing the overall integrity and stability of the shield structure.
Highway and railway construction: In other infrastructure projects such as highway and railway tunnels, shield mortar also plays an important role.
| project | Technical indicators |
| Fluidity (s) | 60±10 |
| Bleeding rate(%) | ≤3.5 |
| Apparent density/(kg/m³） | ≥1700 |
| Apparent Condensation Time (h) | ≤5.0 |
| Initial setting time (h) | ≤16.0 |
| Consolidation rate（%） | ≥95.0 |
| Compressive strength (28d, MPa) | ≥3.0 |
Main product features:
1. Excellent fluidity: Shield tunneling mortar has good fluidity, making it easy to pump and construct, and can effectively fill the gaps between the pipe segments and the formation.
2. Good compactness: This mortar has good compactness, which can reduce water leakage, seepage and other phenomena, ensuring the safety and stability of tunnel structures.
3. High strength: The shield mortar has high strength and can withstand the pressure of the formation, protecting the tunnel from damage.
4. Non layered segregation: This means that the mortar will not show obvious layering after being left to stand for a period of time, maintaining uniform and consistent performance.
5. Good water retention: Shield tunneling mortar has good water retention, which can reduce bleeding and improve construction quality and efficiency.
6. High consolidation rate: The consolidation rate is as high as 98%, which means that the mortar can be tightly filled into the gaps behind the pipe wall after solidification, providing better support and sealing effect.
7. Green and environmentally friendly: Modern shield mortar emphasizes environmental performance, does not contain harmful substances, reduces environmental pollution and resource waste, and conforms to the concept of sustainable development.
Mainly used for shield tunneling construction in underground spaces such as subways and tunnels, enhancing the overall integrity and stability of shield tunneling structures.
Used as a ground reinforcement material in infrastructure construction such as highways and railways to improve the bearing capacity and impermeability of the ground.
Waterproof engineering for facilities such as garbage bins and incineration power plants.
