Portable concrete slump testing device for hydraulic engineering supervision

The utility model discloses a portable concrete slump testing device for hydraulic engineering supervision. The portable concrete slump testing device is used for solving the problem that the wall of an existing portable testing cone is easy to be uneven in the using, transition and storage processes. The concrete slump testing device comprises a testing body and a funnel, and the testing body is of a steel-plastic composite structure and comprises a conical cylinder located inside, a shell located outside and filler located between the conical cylinder and the shell; the conical cylinder is a trumpet-shaped stainless steel conical cylinder with an upper opening of 100mm, a lower opening of 200mm and a height of 300mm; the shell is an engineering plastic injection molding part, and at least two vertical faces of the shell are provided with inwards-concave handles used for drawing and upward pulling. According to the device, local concave-convex deformation of the internal conical cylinder part caused by exter
