SGU-8 Cement Grouting Pump Machine and Grout Mixer Machine for Tunnel Lining
Products Description
SGU-8.0 Vault Grouting pump with mixer is a special grouting machine for tunnel lining, which is mainly used for tunnel lining trolley vault with mold grouting construction.The all-in-one machine for grouting with mold on the vault adopts a double-layer design, the upper layer makes grout, the lower layer mixes grout, the front end grouts, and the grouting flow are automatically printed, realizing one device stirring grouting construction of one equipment. While reducing equipment investment, it improves grouting efficiency and reduces the labor intensity of on-site operators.
The working principle of the all-in-one grouting machine with mold for the vault
Tunnel lining vault plate with grouting construction technology, 4 vertical grouting holes is set on the plate of the trolley vault of the second lining of the tunnel, and reactive powder ultra-high strength concrete (RPC) grouting pipes are installed in the holes, and the second lining concrete is poured 1 to 2 hours after completion, start grouting before off model.The grouting material is filled with high-fluidity micro-expansion early-strength and slow-setting mortar, which forms an organic whole with the second-lined concrete, which solves the disadvantages of the traditional grout and the second-lined concrete two skins.The grouting is operated by the integrated grouting and mixing machine with mold on the vault. The grouting material has the characteristics of micro-expansion, high fluidity, early strength, no bleeding, and slow setting. It not only plays the role of cavity filling, but also can compensate or the role of repairing the defects of the second lining concrete.

Technical advantages of SGU-8.0 Vault Grouting pump with mixer with Mold
1.Via simplifying the embedded pipe and grouting construction technology, improving the grouting tooling and lining micro-expansion grouting binder materials, the concealed project of lining vault pouring are transformed into a “visible” project, and the lining vault defect is prevented.
2.The micro-expansion grouting binder can repair defects such as construction gap, cold joints, concrete inconsistencies, missing edges and corners, etc.; Through the penetration of slurry, the damage of the waterproof board can be blocked, forming a “mushroom” plug, which has the function of water blocking.
3.The Vault Grouting Integrated Machine with Die integrates the functions of mixing, slurry making, slurry storage and grouting,and has a high grouting pressure, which can fully overcome the pipeline resistance of the slurry with low water-material ratio and the vertical transport of the slurry
4.Using the support of the lining trolley, the concrete is poured and grouted in time. The construction time is short and does not affect other processes.
5.Count the amount of lining grouting for each ring, implement process management and assessment, and force the construction team to improve the quality of lining grouting.
