[0002] With the continuous expansion of water conservancy project construction and technological advancements, the requirements for reinforced concrete protective structures are becoming increasingly stringent. Currently, building construction and municipal engineering projects have implemented a series of quality control measures to ensure the quality of reinforced concrete protective layers. The application of precise control technology will help improve the overall quality and safety of water conservancy projects and reduce maintenance and operating costs. At the same time, with the increasing awareness of environmental protection and sustainable development, green and environmentally friendly materials and technologies will be more widely used, providing new development opportunities for the precise control of reinforced concrete protective structures in water conservancy projects.

[0003] However, in order to improve the durability of the existing reinforced concrete protection structure of water conservancy projects, a protective layer is generally set on the outside. However, the bonding mechanism between the existing protective layer and the internal concrete is low, which makes it easy for the two to fall off and crack, resulting in low overall protection effect and shortened service life.

A wear-resistant layer is cast on the outside of the concrete layer, and the outer surface of the concrete layer is provided with several groups of first slots and several groups of second slots, and the first slots and the second slots are alternately arranged on the outer surface of the concrete layer. A first plug block and a second plug block are integrally formed on the wear-resistant layer, and the first plug block is fixed in the first slot, and the second plug block is fixed in the second slot. A barb is also fixed on the outer surface of the concrete layer, and a hook groove is integrally formed on the wear-resistant layer, and the barb is fixed in the hook groove.

[0006] Preferably, the wear-resistant layer is configured as a protective layer containing nano-SiO2.

[0007] Preferably, the first slot and the second slot are both arranged to be tilted, and the tilt directions are opposite.

[0008] Preferably, a metal mesh layer is further provided inside the wear-resistant layer, and the metal mesh layer is provided on four sides of the wear-resistant layer.

[0009] Preferably, several groups of support rings are provided inside the several groups of steel bars, the outer surfaces of the support rings are fixedly connected to the steel bars, and the outer surfaces of the several groups of steel bars are spirally wound with steel bars.

[0010] Preferably, a cross support frame is welded to the inner side of the support ring, and a limiting groove for welding and fixing with the steel bar is opened on the outer surface of the support ring.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model pours a wear-resistant layer outside the concrete layer and adopts a wear-resistant layer containing nano-SiO2, so that the surface of the protective structure has better wear resistance and durability. At the same time, nano-SiO2 can improve the compressive strength, carbonization resistance, impermeability, frost resistance and crack resistance of the wear-resistant layer, thereby increasing the protective effect of the wear-resistant layer, extending the life cycle of the building, and improving the overall durability and crack resistance of the protective structure. At the same time, through the cooperation of the first slot, the second slot and the first plug and the second plug, the bonding mechanism between the wear-resistant layer and the concrete layer can be improved, thereby improving the connection stability.

At the same time, steel bars are welded on the outer surface of the steel bar in a spiral manner, which can further improve the stability of the steel bar structure, thereby improving the overall compressive strength and bearing capacity of the protective structure, which is conducive to improving the overall service life.
