Novel leakage-proof slump barrel

The invention relates to the technical field of building concrete equipment, in particular to a novel leakage-proof slump barrel which comprises a slump barrel body, the lower end of the slump barrel body is fixedly connected with a bottom steel plate, meanwhile, the outer side of the lower portion of the slump barrel body is sleeved with a half sleeve, and the bottom steel plate is arranged at the lower end of the interior of the half sleeve; a positioning convex ring is arranged on the outer side of the slump barrel, a fixing ring is arranged at the upper end of the outer side of the half sleeve, the positioning convex ring and the fixing ring are fixedly connected through a plurality of connecting assemblies, and the connecting assemblies evenly surround the outer side of the half sleeve. The lower end of the slump barrel is fixedly connected with the bottom steel plate, and after fixed connection, the slump barrel is fixedly connected with the half sleeve to form a complete leakage-proof structure, so tha
