AI Technical Summary
Existing sheet piles have deficiencies in connection stability and resistance to wind and wave impact, resulting in poor river slope reinforcement effects.
A prefabricated concrete hollow sheet pile was designed, which used mortise and tenon grooves and mortise protrusions for the initial connection, and formed a second layer of connection through grouting grooves and connecting reinforcement. At the same time, an impact-proof arc surface was set on the surface of the pile to decompose the impact force of wind and waves.
The connection stability and wind and wave resistance of the sheet piles are improved, and the reinforcement effect of the river slope is enhanced.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0023] like Figures 1 to 3 As shown, a prefabricated concrete hollow sheet pile includes a pile column 1, a hollow hole 2, a mortise groove 3, a mortise protrusion 4, a first grouting groove 5, a second grouting groove 6, a connecting rib 7, an impact-proof arc surface 8, a tapered pile tip 9, and a reinforcing vertical bar 10.
[0024] A hollow hole 2 is provided inside the pile column 1, mainly to reduce the counterweight of the entire pile column 1 and facilitate transportation. After the pile column 1 is driven, some stones or gravel can be filled inside to increase stability.
[0025] The four side walls of the hollow hole 2 are provided with a plurality of reinforcing vertical bars 10, and the four corners of the hollow hole 2 are arc-shaped chamfered structures. These structures can improve the strength of the hollow hole 2 and avoid damage during the pile driving operation.
[0026] A conical pile tip 9 is provided at the bottom of the pile column 1 to facilitate smoother piling operations.
[0027] The left side of the pile column 1 is symmetrically provided with tenon grooves 3 in the front and back, and the right side is symmetrically provided with tenon protrusions 4 in the front and back. The tenon protrusions 4 of two adjacent pile columns 1 are inserted into the corresponding tenon grooves 3.
[0028] The tenon protrusion 4 is a convex structure.
[0029] By inserting the mortise protrusions 4 into the corresponding mortise grooves 3, the connection between adjacent piles 1 can be made tighter, and the convex structure improves the waterproof performance.
[0030] A first grouting groove 5 is provided in the middle of the left side of the pile column 1 and a second grouting groove 6 is provided in the middle of the right side. A number of connecting ribs 7 are provided in the second grouting groove 6 from top to bottom. One end of the connecting rib 7 is connected to the pile column 1 and the other end passes through the second grouting groove 6. The connecting rib 7 is a U-shaped structure.
[0031] The first grouting groove 5 and the second grouting groove 6 are semicircular structures, and the first grouting groove 5 and the second grouting groove 6 of two adjacent pile columns 1 are connected to form a grouting channel.
[0032] After the pile columns 1 are connected, cement slurry can be injected into the grouting channel formed by the first grouting groove 5 and the second grouting groove 6 to better connect the two pile columns 1 together. The connecting ribs 7 make the connection stronger.
[0033] The front of the pile 1 is provided with an anti-impact arc surface 8, which can decompose the impact force of the water flow into different directions and reduce the direct impact force.
