Cement mixer

Abstract

The invention relates to a building construction device, in particular to a cement mixer which carries out cement grouting operation to a reserved bellow pore channel after stretching the reinforcing steel bar in a reinforced concrete structure. The cement mixer mainly comprises a mixing drum which is provided with a motor and a stock outlet, the motor is connected with a vertical axis in the mixing drum, and the vertical axis is provided with a group of mixing blades and two groups of mixing blades. As a group of mixing blades are added on the basis of one group of mixing blades in the prior art, the cement can be mixed fully and evenly in the mixing drum, thus meeting the demand that the water cement ratio of the cement used for grouting is about 0.4 in the national construction specifications.

Description

technical field

[0001] The invention relates to construction equipment, in particular to a cement slurry mixer for pouring cement slurry into reserved corrugated pipe holes after tensioning of steel bars in a reinforced concrete structure is completed. Background technique

[0002] At present, for the bonded prestressed steel bars in the prestressed concrete construction, it is necessary to pour cement slurry into the reserved corrugated pipe holes after the steel bars are tensioned. In order to ensure the smooth progress of grouting and the quality of grouting, the construction specifications of our country require that the water-cement ratio of the grouting cement is about 0.4. However, due to the limitation of the structure of the existing mixing equipment, the mixing speed is slow and the mixing blades in the mixing drum are in There is a working blind area in the mixing drum, so that the cement slurry cannot be fully and uniformly stirred, so it cannot meet the requirem...
