[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0018] See also Figure 1 and Figure 3 A concrete square pile refers to a square pile made of concrete and steel bars or steel wires. It has the advantages of easy manufacture, high pile body strength, good corrosion resistance, and low price. The utility model provides a technical solution: a high-strength and corrosion-resistant concrete square pile, comprising a first pile body 1 and a second pile body 2, wherein the second pile body 2 is located below the first pile body 1, and the first pile body 1 and the second pile body 2 are both configured as concrete structures. A steel cage 8 is disposed inside the first pile body 1 and the second pile body 2, and the steel cage 8 is composed of main bars, spiral stirrups, and frame bars. The steel cage 8 mainly plays a tensile role, and constrains the pile body concrete of the first pile body 1 and the second pile body 2, so that it can withstand a certain axial tension.

[0019] In this embodiment, please refer to Figure 1 and Figure 2 A first connecting plate 3 and a second connecting plate 4 are respectively installed on opposite sides of the first pile body 1 and the second pile body 2, a positioning column 5 is installed at the bottom of the first connecting plate 3, and a positioning groove 6 is provided on the top of the second connecting plate 4, the positioning column 5 and the positioning groove 6 are distributed in a triangular array, and the positioning column 5 is inserted into the corresponding positioning groove 6, and a connecting component 7 is arranged between the first connecting plate 3 and the second connecting plate 4, and the connecting component 7 includes a fixing groove 71 respectively arranged around the first connecting plate 3 and the second connecting plate 4, a threaded column 72 is installed in the groove of the fixing groove 71, and the number of the threaded columns 72 in the fixing groove 71 is set to two, and a fixing plate 73 is embedded between the upper and lower fixing grooves 71, the threaded column 72 penetrates the fixing plate 73 and is sleeved with a fastening ring 75, and the fixing plate 73 is provided with four through holes 74 for the threaded column 72 to pass through, and the fastening ring 7 5 is threadedly connected with the threaded column 72. When the first pile body 1 and the second pile body 2 need to be connected, the positioning column 5 on the first connecting plate 3 is aligned and inserted into the positioning groove 6 on the second connecting plate 4, thereby realizing the positioning operation of the first pile body 1 and the second pile body 2. At this time, the fixing groove 71 on the first connecting plate 3 and the fixing groove 71 on the second connecting plate 4 form a whole. The through hole 74 on the fixing plate 73 is aligned with the threaded column 72 and inserted so that the fixing plate 73 is completely pressed into the fixing groove 71. Then, the fastening ring 75 is put on the threaded column 72 and tightened, so that the first connecting plate 3 and the second connecting plate 4 can be connected and fixed, so that the first pile body 1 and the second pile body 2 do not need to be connected by welding, so as to avoid the connection being disturbed by various factors, ensure the connection strength of the pile body, and not prone to quality problems.
