Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel secondary lining construction, and particularly relates to a concrete distribution system with double discharge outlets. BACKGROUND

[0002] With the continuous improvement of tunnel construction, especially high-speed rail tunnel standards, the requirements for concrete into the mold conditions are also getting higher and higher. The current full chute pouring method has been gradually replaced by automatic distribution systems, such as rotary distribution mechanisms and automatic distribution systems with longitudinal movement of the trolley. However, these systems mostly use one-way distribution when pouring into the mold. Workers need to switch the distributor inlet to pour on the other side after pouring on one side to prevent the mold from being biased and deviated due to continuous pouring on one side. Frequent switching of pouring positions increases the workload of workers and reduces construction efficiency. When switching the pouring position, excess concrete will flow onto the support base, which will affect the switching of the pouring position and need to be cleaned by workers in time. After the distributor is connected to the pouring pipe, concrete particles will adhere to the inner wall of the connecting sleeve on the distributor, which will scratch the conveying pipe on the distributor and cause a loose seal, resulting in leakage when conveying concrete.
