Innovation Solution
An apparatus and method that involve mixing bubbles, fiber-mixed material, and silica fume into normal concrete to form fiber-reinforced concrete, followed by high-pressure air blowing to reduce excessive air and slump, allowing for efficient shooting and conversion of normal concrete into fiber-reinforced concrete at construction sites, enhancing production capacity and workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bubbles are inserted into normal concrete to form fiber-reinforced concrete, then production capacity is improved and construction time is shortened, but excessive air and increased slump occur in the concrete
Solution Approach 1:
The patent extracts and removes excessive air bubbles from the fiber-reinforced concrete through a drainage device equipped with a roller and suction mechanism. The roller rotates to bring drainage holes into contact with the concrete surface, creating negative pressure that extracts excess air and water, thereby controlling air content while maintaining production efficiency
Solution Approach 2:
The patent introduces a drainage device as an intermediary component between the concrete mixing process and final placement. This device acts as a mediator to remove excess air and water, enabling the concrete to achieve proper air content and slump control without compromising production capacity
2Strength
If fiber-mixed material is dispersed into normal concrete to create fiber-reinforced concrete, then concrete strength and toughness are improved, but fiber conglomeration and uneven dispersion occur
Solution Approach 1:
The patent employs a vibration mechanism with vibration heads that contact the concrete in the hopper. The vibration causes the fiber-mixed concrete to vibrate and settle, preventing fiber conglomeration and ensuring uniform dispersion of fibers throughout the concrete matrix, thereby maintaining concrete strength while improving dispersion uniformity
Solution Approach 2:
The patent changes the physical state and distribution parameters of fibers through controlled vibration and drainage processes. By adjusting vibration frequency and drainage rate, the system optimizes fiber dispersion uniformity while preserving the strength-enhancing properties of the fiber reinforcement
3Manufacturing precision
If complex equipment is used to manufacture fiber-reinforced concrete, then fiber dispersion quality is improved, but construction costs increase
Solution Approach 1:
The patent merges the vibration mechanism and drainage device into an integrated system mounted on the shotcrete truck. This combination achieves improved fiber dispersion quality and air content control through a unified equipment structure, avoiding the need for multiple separate complex devices and thereby controlling construction costs

AI summary
The present invention relates to an apparatus for manufacturing fiber-reinforced concrete through shooting after inserting bubbles into normal concrete and a method for manufacturing the same, which: form fiber-mixed concrete in which the bubbles, fiber-mixed materials, and silica fume are mixed in the normal concrete or form the fiber-mixed concrete in which aggregates, water, and the bubbles are put into and mixed with a mixture, in which cement, the fiber-mixed materials, and silica fume are mixed; and then shoots the fiber-reinforced concrete in which excessive air included in the fiber-mixed concrete is reduced by spraying the fiber-mixed concrete with the high-pressure air when the fiber-mixed concrete is discharged, and of which a slump, drastically increased due to the large amount of bubbles, is reduced to a range of the slump of the normal concrete, thereby improving the production capacity of the fiber-reinforced concrete and shortening operating time.
