Description

Technical Field

[0001] The present invention relates to the technical field of concrete processing, and more particularly to a high-strength concrete and a processing system and method thereof. Background Art

[0002] High-strength concrete is mainly composed of raw materials such as cement, sand, stone, as well as admixtures and additives such as high-efficiency water reducer, fly ash, mineral powder, slag, and silica powder. These materials are prepared through conventional processes to obtain concrete with strength grades of C50 to C80, or even above C100. Among them, cement, as the core cementitious material, its type and performance have a crucial influence on the strength of concrete. Portland cement or ordinary Portland cement is often used to prepare high-strength concrete due to its good hydration properties and strength performance. During the preparation process, the use of high-efficiency water reducer can significantly reduce the water-cement ratio of concrete, thereby improving the strength and fluidity of concrete. At the same time, the addition of admixtures such as fly ash and mineral powder can not only improve the working performance of concrete, but also improve the durability and impermeability of concrete.

[0003] Since high-strength concrete hardens quickly, the time window from mixing to pouring is very limited. Once mixed or poured improperly, it is easy to cause quality problems. On the other hand, after high-strength concrete is formed, it becomes very difficult to reshape due to its high strength and brittle characteristics. Summary of the invention

[0011] It also includes a probe mechanism, the probe structure includes a probe tube, a window is arranged on one side of the probe tube close to the mold body, a scraper is slidably connected to the probe tube in the window, the scraper is perpendicular to the axis of the probe tube, the bottom of the scraper is fixedly connected to the first telescopic cylinder, the first telescopic cylinder is fixedly connected to the inside of the probe tube, and a connecting frame is fixedly connected to the end of the probe tube away from the mold body, and the connecting frame is fixedly connected to the second telescopic cylinder;

[0012] The connecting disk is an annular structure, and there are circular openings at the left and right ends when the two mold bodies are closed; the circular openings overlap with the inner wall of the connecting disk to form two channels, and two probe mechanisms are arranged in mirror symmetry on the left and right; the two probe tubes can be slidably connected in the two channels.

[0013] A high-strength concrete processing system, a movable wall is rotatably connected to the outer wall of the probe tube close to the mold body, and the outer wall surface of the movable wall fits the inner wall at the circular mouth when the two mold bodies are closed.

[0033] Further explain the working principle of the mold:

[0034] The mold is used in conjunction with a high-strength concrete internal structure, which includes two connecting plates 8, one on the left and one on the right. Straight bars 9 evenly distributed around the circumference are fixedly connected between the two connecting plates 8, and the outer periphery of all the straight bars 9 is evenly distributed and fixedly connected with winding bars 10. The left and right ends of the straight bars 9 pass through the two connecting plates 8 respectively. The high-strength concrete internal structure is placed in the mold body 5 below. The connecting plates 8 are evenly distributed around the circumference. The mold body 5 is provided with through holes corresponding to the threaded holes, so that the two connecting plates 8 are detachably connected to the left and right ends of the mold body 5 respectively; then the inside of the two mold bodies 5 is coated with mold release oil, and concrete is poured on the high-strength concrete internal structure. The winding bars 10 and the straight bars 9 can keep the concrete from overflowing from the mold body 5 below, but can make the concrete higher than the mold body 5 below, and then the edge 6 of the second mold body 5 is detachably connected to the edge 6 of the lower mold body 5. The two molds are driven to rotate, so that the internal concrete is centrifugal and gradually evenly distributed on the inner walls of the two mold bodies 5, and covers the straight bars 9 and the winding bars 10. The two moulds can be heated to achieve the concrete setting.

[0038] A movable wall 12 is rotatably connected to the outer wall of the probe tube 11 on the side close to the mold body 5. The outer wall surface of the movable wall 12 fits with the inner wall at the circular mouth when the two mold bodies 5 are closed. When the movable wall 12 enters the two mold bodies 5 of the probe tube 11, there is a gap between the outer wall of the probe tube 11 and the edges of the two mold bodies 5 at the circular mouth.
