Problems solved by technology
The main problem of this device is that the process of using the piston to squeeze the slurry to make it flow will cause the pressure of the slurry to increase, resulting in greater resistance to the steel fibers when they are rotated by the magnetic field, and the actual fiber orientation effect is poor.
Therefore, the device is also not suitable for ultra-high performance concrete with poor workability
In addition, the discharge port of the device is too small, which makes it difficult for the device to realize large-scale directional pouring of ultra-high performance concrete fibers
[0005] In summary, in actual pouring, the effect of fiber orientation in ultra-high performance concrete by the above two fiber orientation methods is not ideal

The invention discloses an ultra-high performance concrete fiber orientation device. The ultra-high performance concrete fiber orientation device comprises a feeding structure, a vertical parallel channel, an oblique parallel channel wound with a coil used for generating a constant magnetic field and a fixed frame. The feeding structure is installed at an upper port of the vertical parallel channel. The vertical parallel channel comprises a plurality of vertical single channels arranged in parallel. The oblique parallel channel comprises a plurality of oblique single channels arranged in parallel. Movable joints are formed at the joints of the vertical single channels and the corresponding oblique single channels. An angle adjusting device is arranged between the oblique parallel channel and the fixed frame so that the oblique parallel channel can rotate relative to the vertical parallel channel. A vibration device used for enabling the fixed frame to vibrate is installed on the fixedframe. The invention further discloses an ultra-high performance concrete fiber orientation pouring method. The ultra-high performance concrete fiber orientation device can adapt to ultra-high performance concrete with different workability, and the ultra-high performance concrete fiber orientation effect is more ideal.
Description
technical field [0001] The invention relates to ultra-high-performance concrete fiber orientation technology, in particular to an ultra-high-performance concrete fiber orientation device. In addition, it also relates to a method for directional pouring of ultra-high performance concrete fibers. Background technique [0002] Concrete is one of the most widely used and established basic materials in civil engineering. With the development of science and technology, the invention and application of high-efficiency water reducer, mineral ultrafine powder and fiber materials, concrete materials are developing towards ultra-high performance concrete with ultra-high strength and ultra-high durability as the main features. Marked by strength, the development of concrete has experienced the development of normal strength concrete (NSC), high strength concrete (HSC), and ultra high strength concrete (UHPC). Ultra-high-performance concrete has a strength of more than 150Mpa, a tensil...
