Description

Technical Field

[0001] The utility model relates to the technical field of mortar preparation, in particular to shield mortar making equipment. Background Art

[0002] The shield tunnel boring machine is an important construction machinery in shield construction. Due to the advantages of shield construction such as safety, reliability, low environmental impact, low labor intensity, small earthwork volume and high efficiency, it is widely used in urban rail, water conservancy, municipal engineering, mining, highway, railway tunnel and other fields. Because shield tunnel boring machines are often constructed in complex and long-distance working environments, their transmission system must be able to withstand heavy loads and large impacts, and have functions such as in-hole tool change. The slurry balance shield can send the prepared mud into the mud and water bin to form a water-impermeable mud film at the excavation face. The pressure established by the mud film balances the water and soil pressure of the heading face and supports the tunnel heading face;

[0003] In the preparation process of existing mortar, the materials and stirring liquid are placed inside the stirring tank for stirring, which results in a long stirring time. The stirring liquid can only be added after the materials are completely mixed, which reduces the stirring efficiency. At the same time, after the stirring tank stirs the stirring blades and the materials and discharges the materials, some residual materials will adhere to the inner wall of the stirring tank. If they are not rinsed off in time, it will not only affect the next mixing work, but also shorten the service life of the tank. In view of the above problems, the inventor proposes a shield slurrying equipment to solve the above problems. Utility Model Content
