The following description is provided with reference to the accompanying drawings to assist in a comprehensive understanding of various embodiments of the utility model as defined in the claims and their equivalents. The description includes various specific details to aid in understanding, but these details should be regarded as merely exemplary. Accordingly, those skilled in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the utility model.

In the description of the present utility model, references to orientation descriptions such as upper, lower, front, rear, left, right, etc. are based on the orientation or positional relationship shown in the drawings, only for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element in question must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

It will be understood that when an element (e.g., a first element) is "connected" to another element (e.g., a second element), the element can be directly connected to the other element or there can be intervening elements (e.g., a third element) between the element and the other element.

The embodiment of the present utility model provides a connection structure of square piles, as shown in fig. 1 to 4, including an upper section pile 100, a lower section pile 200, two reinforcements 400 and a connection hoop 500, wherein both the upper section pile 100 and the lower section pile 200 may be prefabricated prestressed concrete square piles, and both the shapes and the sizes may be the same. The upper section pile 100 is positioned above the lower section pile 200, and the end surfaces of the upper section pile and the lower section pile can be aligned with each other when the piles are connected. End faces of the upper section pile 100 and the lower section pile 200 adjacent to each other are provided with end plates 300, and the end plates 300 are fixed to the end faces, and can be anchored with the reinforcing bars inside the respective upper section pile 100 and lower section pile 200. When pile extension is performed, the end plate 300 of the upper section pile 100 and the end plate 300 of the lower section pile 200 are tightly fixed together. Both the reinforcing members 400 and the connection cuffs 500 may be square-like, and the two reinforcing members 400 are respectively sleeved on the outer sides of the upper section piles 100 and the lower section piles 200, which may improve the bending resistance and vertical bearing capacity of the pile-connecting portion, and may not interfere with the connection of the end plates 300. The connection cuffs 500 are then hooked on the outer sides of the two stiffeners 400 to connect the two stiffeners 400 together. Because the end plate 300 of the upper section pile 100 and the end plate 300 of the lower section pile 200 are tightly fixed together, compared with the traditional pile splicing structure, the upper section pile 100 and the lower section pile 200 are further connected through the connection of the end plates 300, so that the bending bearing capacity of the pile splicing connection is increased, the gap between the end plates 300 of the upper section pile 100 and the end plates 300 of the lower section pile 200 can be greatly reduced, water in soil is difficult to enter between the end plates 300, the anti-seepage effect can be achieved, and the corrosion damage to the end plates 300 is reduced.

In some embodiments, the connecting ferrule 500 is formed by combining two ferrule members 501, and when piling, the two ferrule members 501 are sleeved outside the reinforcement member 400, and then the two ferrule members 501 are connected together to form the connecting ferrule 500, so that the mounting mode of the connecting ferrule 500 is more flexible, quick mounting can be realized, and compared with the traditional mode of butting a mechanical joint with a butting hole, the time for aligning the mechanical joint with the butting hole can be saved, thereby improving the piling efficiency.

Further, the two cuff members 501 are welded to each other in a manner that is easy to handle and that facilitates quick fastening of the two cuff members 501 together.

This increases the tightening force of the connector ferrule 500, and provides a supporting force by using the protrusions 410, thereby playing a role of clamping, preventing the connector ferrule 500 from sliding on the pile body, and facilitating positioning and mounting of the connector ferrule 500.

Further, the plurality of caulking grooves 510 may be distributed in a lateral direction, and vertical plates 511 extending vertically are formed between two adjacent caulking grooves 510, and can improve the bending resistance of the pile.

In some embodiments, the connector ferrule 500 includes a connector plate 520, the outer side of the reinforcement member 400 is provided with a groove 420 that mates with the connector plate 520, and the connector plate 520 is embedded in the groove 420. This can further increase the hooping force of the connection ferrule 500 to can utilize the recess 420 to provide supporting force, further play the screens effect, avoid connection ferrule 500 to slide on the pile body, the connection plate 520 inlays behind the recess 420, and connection ferrule 500 can be installed in place, conveniently carries out location installation to connection ferrule 500.

Further, the connection plate 520 extends in the lateral direction to meet the performance requirement of being bent in synchronization with the riser 511.

Both cuff members 501 include webs 520, and the webs 520 of the two cuff members 501 are welded together when the two cuff members 501 are connected.

In some embodiments, the end plate 300 of the upper section pile 100 and the end plate 300 of the lower section pile 200 are welded and fixed together, and in particular, a circle of welding can be fully performed around the end plate 300, which can thoroughly seal the gap between the end plate 300 of the upper section pile 100 and the end plate 300 of the lower section pile 200, so that water cannot enter between the end plate 300 of the upper section pile 100 and the end plate 300 of the lower section pile 200, and corrosion damage to the end plate 300 is greatly reduced.

In some embodiments, the connection ferrule 500 is welded to the reinforcement member 400, which may improve the pullout resistance of the pile structure. Wherein the above-described riser 511 may be welded to the reinforcement 400.

In some embodiments, the reinforcement 400 is secured to the outside of the upper section stake 100 and the lower section stake 200 by anchors.
