Problems solved by technology

In order to ensure the smooth progress of grouting and the quality of grouting, my country's construction regulations require that the water-cement ratio of the grouting slurry is about 0.4, but the existing mixing equipment is limited by its structure, and its stirring speed is relatively slow and the mixing blades in the mixing drum are There is a working blind area in the mixing drum, so that the cement slurry cannot be fully and uniformly mixed, so it cannot meet the requirements of the above construction specifications, especially when the cement slurry in the mixing drum is close to full load.

Embodiment 1

[0007] Example 1: Refer to the accompanying drawings. Inject water (tap water) and cement into the mixing drum. When the motor works, it drives the vertical shaft and drives the mixing blades to rotate. Because the upper and lower sets of mixing blades on the vertical shaft simultaneously affect the water and cement in the mixing drum After stirring, the water and cement are fully and evenly mixed to make it into cement slurry, and the mixed cement slurry flows out from the slurry outlet to provide a cement slurry with a water-cement ratio of about 0.4 that meets the requirements of my country's construction specifications. The purpose of the invention is achieved by the use of the grouting operation of the pipe orifice.

Embodiment 2

[0008] Example 2: refer to the accompanying drawings. In this embodiment, on the basis of Embodiment 1, the angle between the stirring blade and the horizontal plane is selected to be 30°, which can achieve the better purpose of the present invention.

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...
