Description

Technical Field

[0001] The utility model relates to the technical field of UHPC plastering sprinkler, in particular to a plastering sprinkler device for UHPC. Background Art

[0002] UHPC represents one of the most advanced cement-based composite materials in the world. Its typical characteristics include compressive strength higher than 120MPa, initial crack strength not less than 5MPa, and excellent post-crack tensile properties. The uniqueness of UHPC lies in its high density and the introduction of steel fibers, which give it ultra-high strength, high toughness and excellent durability. This characteristic makes UHPC widely used in structural repair and reinforcement and the construction of new lightweight and high-strength structures, especially for large and complex projects such as cross-sea bridges, offshore oil platforms, nuclear waste storage facilities and military protection projects. Through the application of UHPC, breakthroughs in the performance of traditional engineering structures can be achieved, maintenance and repair costs can be reduced, and lower life cycle costs can be obtained. In addition, the application of UHPC also has significant material saving, energy saving and emission reduction effects, which helps promote sustainable development.

[0003] In order to obtain the best mechanical properties of UHPC, a low water-binder ratio is usually used, the total amount of cementitious materials is limited, sufficient mineral admixtures and chemical admixtures are added, and the amount of cement is minimized. The water-binder ratio refers to the ratio of the amount of water used in concrete to the amount of cementitious materials used. A low water-binder ratio means that the water content in the concrete is relatively low, which helps to improve the strength and durability of the concrete. However, the low water-binder ratio of UHPC will lead to reduced fluidity and increased viscosity of the concrete, which may make the concrete surface construction more difficult.

[0004] At present, in the UHPC preparation process, the method of artificial sprinkling water is often used for concrete surface construction. This method is relatively simple and easy to operate, but the staff cannot spray quantitative water, which will affect the performance of different batches of UHPC test blocks and cannot ensure the consistency of the performance of different batches of UHPC test blocks.
