Description

Technical Field

[0001] The present invention belongs to the field of shield mortar slurry separation, and in particular relates to a device for shield mortar slurry separation and a use method thereof. Background Art

[0002] Shield mortar is mainly used for synchronous grouting of tunnel lining in shield tunnel construction, filling the gap between the tunnel lining (segments) and the surrounding soil, preventing soil loosening and collapse, reducing the direct pressure of soil on the lining, and ensuring the stability and safety of the tunnel. At the same time, the hardened mortar can also improve the waterproof and corrosion resistance of the tunnel. In addition, shield mortar can reduce the friction between the shield machine and the soil, reduce the propulsion resistance of the shield machine, and improve construction efficiency. Therefore, shield mortar plays a very important role in shield tunnel construction. Compared with dry-mixed mortar, wet-mixed mortar does not require material drying, and does not require the installation of storage tanks and mixers at the construction site, reducing site occupation, less environmental pressure, convenient construction, and stable slurry quality. Its fluidity and homogeneity are better than dry-mixed mortar.

[0003] Large particles (greater than 3mm in size) in shield mortar slurry will sink rapidly during the transportation and grouting operation suspension, causing blockage of slurry trucks, shield machine slurry storage tank outlets and grouting hoses, affecting construction progress and causing significant economic losses; dry-mixed mortar can screen out large particles when the raw materials are dried, while wet-mixed mortar can only use raw materials without large particles. The supply of materials that meet the requirements on the market is small, and even customized materials are needed, resulting in high costs and limited material selection; if ordinary materials are screened, they can only be washed with a large amount of water, but a large amount of resources, equipment, site and manpower are invested, and the sand produced may not be used immediately due to too high water content.
