[0002] Concrete refers to concrete used in water conservancy projects and structures that are submerged in water for a long time or frequently subjected to water. The steel plate reinforcement structure for hydraulic concrete is located on the outer surface of hydraulic concrete components such as gate piers, aqueducts, and factory columns. It tightly covers a layer of reinforcement steel plate, which is fixed by fastening bolts and other components, so that the steel plate and the original concrete component form an integral whole and share the load.

[0003] However, existing hydraulic concrete reinforced with steel plates are exposed to humid, freeze-thaw, chloride ion or chemical corrosion environments for a long time. The steel plates are prone to corrosion, which may lead to the separation of the steel plate from the concrete interface, the degradation of the reinforcement effect over time, and even the occurrence of new structural problems. Therefore, it does not meet the current needs. In response, we propose a hydraulic concrete reinforced with steel plates. Utility Model Content

The internal threaded fixing sleeve 7 and the corresponding screw hole 9 contain a fixing screw 10. An L-shaped top fixing plate 6 is fixed to each of the four corners on the outer side of the top end of the concrete column 1. An L-shaped filling tube 11 is fixedly installed on one side of the outer surface of the L-shaped top fixing plate 6. Corrosion-resistant sealant 13 is provided below the L-shaped filling tube 11 and filled between the rust-proof shell 4 and the concrete column 1. When it is necessary to assemble the outer steel plate reinforcement structure, the steel connecting plate 2 and the concrete column corner protection steel plate 3 can be fixed to the outer surface of the concrete column 1 by welding or bolting. After the steel connecting plate 2 and the concrete column corner protection plate 3 are fixed, pick up the rust-proof shell 4, align the positioning groove 8 on the outer surface of the rust-proof shell 4 with the internal thread fixing sleeve 7 fixed on the outer surface of the steel connecting plate 2, and push it towards the steel connecting plate 2 until the top end of the internal thread fixing sleeve 7 is inserted into the positioning groove 8.

When building the sealing square sleeve, the two anti-rust shells 4 located on the left and right sides of the concrete column 1 are fixed first, and then the two anti-rust shells 4 located at the front and rear of the concrete column 1 are fixed. When the anti-rust shells 4 are fixed in this way, the strip-shaped sealing plate 15 on the outer surface of the anti-rust shell 4 located at the front and rear of the concrete column 1 will be inserted into the strip-shaped sealing groove 14 on the outer surface of the anti-rust shells 4 located on the left and right sides of the concrete column 1, thereby increasing the sealing between the anti-rust shells 4.

[0019] An L-shaped bottom fixing plate 5 is fixed to each of the four corners of the outer surface of the bottom end of the concrete column 1, and the position and shape of the L-shaped bottom fixing plate 5 correspond to the position and shape of the L-shaped top fixing plate 6; the lower end face of the rust-proof shell 4 is provided with a first strip-shaped sealing groove near the concrete column 1, and each of the remaining rust-proof shell 4, except for the first rust-proof shell 4 from top to bottom, is provided with a second sealing groove on the upper end face opposite to the concrete column 1; the upper end face of the L-shaped bottom fixing plate 5 is provided with a third sealing groove, and the first sealing groove on the lower end face of the bottommost rust-proof shell 4 engages with the third sealing groove on the outer surface of the L-shaped bottom fixing plate 5; A fourth sealing groove is provided on the upper surface of the first rust-proof shell 4 from top to bottom, near the concrete column 1. A fifth sealing groove is provided on the lower surface of the L-shaped top fixing plate 6.

The above technical solution can prevent the anti-corrosion sealant 13 from leaking to the outside from between multiple rust-proof shells 4 or from the gaps between the rust-proof shell 4 and the L-shaped bottom fixing plate 5 and the L-shaped top fixing plate 6 when the anti-corrosion sealant 13 is poured.
