The synchronous grouting material is mainly composed of cement, fly ash, fine sand, quick hardening agent, water reducer, rubber powder, hydrophobic agent, expansion agent, and water; These components work together to endow synchronous grouting materials with excellent fluidity, water retention, and stability; Synchronous grouting material plays a crucial role in shield tunneling construction, mainly used to fill the gap between the tail of the shield machine and the pipe segments, in order to prevent deformation of the surrounding soil and control ground settlement. This material can not only improve construction quality and safety, but also effectively protect underground facilities from damage; Synchronous grouting material is used during shield tunneling to ensure the early stability of pipe lining and form the first line of defense for waterproofing. Its main application scenarios include tunnel shield construction, rail transit construction, and installation and maintenance of various underground facilities.

Main product features:
1. Liquidity and permeability:
Synchronous grouting material has excellent fluidity, which enables it to effectively fill the gaps between the shield tail and the pipe segments of the shield machine, and even penetrate into subtle cracks. This characteristic is crucial for ensuring construction quality and structural stability.
2. Strength and durability:
After solidification, synchronous grouting material can form a high-strength solidified body, providing excellent bearing capacity and stability. In addition, it also has good durability and can resist the influence of water, chemicals, and environmental factors, extending the service life of the structure.
3. Environmental friendliness:
Modern synchronous grouting materials are usually made of environmentally friendly materials, which are harmless to the environment and meet the requirements of sustainable development. This makes it an ideal choice for construction in urban and ecologically sensitive areas.
4. Regulatory nature:
The curing time and adhesion of synchronous grouting material can be adjusted according to specific engineering requirements. For example, by adding different additives, the solidification speed can be controlled to adapt to different construction conditions and geological conditions.
5. Widely used:
Due to its versatility and adaptability, synchronous grouting materials are widely used in various types of soil and rock environments. It is not only suitable for tunnel and subway construction, but can also be used in fields such as foundation treatment, underground engineering, geotechnical engineering, water conservancy engineering, and construction engineering.
The main function is to timely fill the gap between the tunnel lining and the ground while the shield machine is advancing, in order to stabilize the ground, reduce ground settlement, and protect the tunnel structure.
