The segregation of concrete is the phenomenon that the cohesive force among the concrete mixture components is not enough to resist the sinking of coarse aggregates, and the components of the concrete mixture are separated from each other to cause the internal components and the structure to be uneven. It is common to present coarse aggregate separated from the mortar, such as by the bottom of a large mix where dense particles settle or the coarse aggregate is separated from the mix as a whole.

In the prior art, a plurality of string barrels are generally adopted to be connected in series in the construction process to assist and additionally provide some buffer devices to prevent segregation, and the structure is complex so that the connection and disassembly process becomes complicated.

Detailed Description

As shown in fig. 1-4, fig. 1 is a cross-sectional view of the anti-segregation concrete cylinder according to the present invention when the number of cylinders is an even number. Fig. 2 is a plan view of the utility model provides a prevent segregation concrete cluster section of thick bamboo when barrel figure is the even number. Fig. 3 is a cross-sectional view of the utility model provides a prevent segregation concrete cluster section of thick bamboo when barrel figure is the odd number. Fig. 4 is the utility model provides a structural schematic diagram of a concrete string section of thick bamboo device of preventing educing.

Referring to fig. 1-3, the utility model provides an anti-segregation concrete string tube, which comprises; the device comprises a cylinder body 1, a rotating shaft 2 and a plurality of blades 3; the cylinder body 1 is provided with a feeding hole and a discharging hole; the rotating shaft 2 is rotatably arranged in the cylinder body 1 and is vertical to the central axis of the cylinder body 1; a plurality of blades 3 are fixedly mounted on the shaft 2 and arranged in an annular array.

The concrete that prevents educing of this embodiment is a string section of thick bamboo in specific course of work, and when the concrete passed through the feed inlet and gets into 1 inside of barrel, the concrete that flows falls on a plurality of blades 3, and the impact force of concrete acts on a plurality of blades 3 to promote a plurality of blades 3 and constantly rotate, so that the concrete falls down from blade 3, and the rethread discharge gate flows.

In the embodiment, the anti-segregation concrete string cylinder is provided, when concrete falls from a feeding hole, the plurality of blades 3 block the falling of the concrete and absorb the impact force of the concrete so as to decelerate the concrete and prevent the concrete from segregation, the plurality of blades 3 rotate after being stressed, and the concrete falls under the guidance of the blades 3;

the blades 3 continuously rotate under the action of the impact force of the concrete to form circulation, and can continuously work to prevent the concrete from being separated.
