[0002] In the process of construction, cement slurry is needed. Usually, the cement slurry needs to be poured into the designated position, and there are strict requirements on the water-cement ratio, grouting density and grouting pressure of the poured cement slurry to ensure the reliability of the building quality.

[0003] At present, the slurry making process is generally completed in a mixing slurry making machine. The cement slurry after mixing is then pumped to the location where grouting is required through a pumping system. At the same time, a special grouting vehicle has also been developed, which is mainly used to make prefabricated parts. The mixed grouting material is placed in a silo, and then the corresponding prefabricated parts are poured through a conveying pipe at the lower end of the silo. In order to improve the grouting efficiency, two or three grouting outlets are also set at the lower end of the silo. However, multiple grouting outlets make it difficult to control the discharge speed, resulting in overflow of the grouting material or insufficient grouting. Utility Model Content

[0034] An embodiment of the utility model provides a double-row grouting device, comprising:

[0035] Stand 1;

[0036] A main hopper 2, which is arranged at the top of the platform 1, comprises a main silo 201 for temporarily storing grouting material and a first valve 202 arranged at the output end of the main silo 201;

[0049] Specifically, the output ends of the first grouting ash hopper 412 and the second grouting ash hopper 422 are provided with a second valve 6. It can be understood that the provision of the second valve 6 can achieve double-row different pouring flow rates.

[0052] Specifically, a hoist 7 is also provided at the top of the stand 1. The hoist 7 is not specifically limited and only needs to be able to hoist the grouting hopper.
