[0032] In addition, the terms "first", "second" and the like are only used for differentiation in description and cannot be understood as indicating or implying relative importance

[0033] In the description of the utility model, it is also necessary to explain that, unless otherwise explicitly specified and limited, the terms "arrangement", "connection" and the like should be understood in a broad sense, for example, "connection" can be fixed connection, can also be detachable connection, or integrally connected: can be mechanical connection, can also be electrical connection: can be direct connection, can also be indirect connection through an intermediate medium, can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0034] As shown in the accompanying Figure 1 As shown in the accompanying Figure 3 The utility model provides a kind of underwater bored pile reinforcement structure provided in the embodiment, including reinforcement cage a, the end of two adjacent described reinforcement cage a Threaded joint b is connected by connector;The connector includes two internal thread rings 1 respectively arranged on two described end Threaded joint b, and sleeve 2 for connecting two described internal thread rings 1, the sleeve 2 is connected by two symmetrically arranged half-round ring body 21;Two connecting pieces 3 are respectively arranged in the connecting place of two described half-round ring body 21;Single described connecting piece 3 includes with the inner wall of two described half-round ring body 21 abutment one inner arc clamping plate 31, with the outer wall of two described half-round ring body 21 fixedly connected one outer arc fixed plate 32, and the connecting gap of two described half-round ring body 21 is connected and is used for connecting the flat plate 33 of inner arc clamping plate 31 and outer arc fixed plate 32.

[0035] The phrase "an inner arc-shaped clamp 31 that abuts against the inner walls of the two semicircular rings 21" refers to the alignment of the centerline of the inner arc-shaped clamp 31 with the connecting centerline of the two semicircular rings 21, ensuring that the contact area between the inner arc-shaped clamp 31 and the two semicircular rings 21 is the same. The outer surface of the inner arc-shaped clamp 31 (the surface that contacts the inner surfaces of the two semicircular rings 21) has the same shape as the inner surfaces of the two semicircular rings 21 to ensure a tight fit. The phrase "an outer arc-shaped fixing plate 32 that is fixedly connected to the outer walls of the two semicircular rings 21" refers to... The centerline of the outer arc-shaped fixing plate 32 is aligned with the connection centerline of the two semi-circular rings 21 to ensure that the contact area between the outer arc-shaped fixing plate 32 and the two semi-circular rings 21 is the same. The inner side surface of the outer arc-shaped fixing plate 32 (the surface that contacts the outer side surface of the two semi-circular rings 21) has the same shape as the outer side surface of the two semi-circular rings 21 to ensure a tight fit. The length of the flat plate 33 should be the same as the thickness of the connection point of the semi-circular rings 21 to ensure that the inner arc-shaped clamping plate 31 and the outer arc-shaped fixing plate 32 can fully clamp the semi-circular rings 21. Preferably, the thickness of the flat plate 33 should be less than or equal to 2 mm to reduce the seam between the two semi-circular rings 21.

[0036] Furthermore, as shown in the appendix Figure 4 As shown, a groove 24 is provided on the outer wall of the semicircular ring 21 near the connection point. The groove formed by the two grooves 24 on the two semicircular rings 21 matches the outer arc-shaped fixing plate 32. This arrangement helps to strengthen the connection between the outer arc-shaped fixing plate 32 and the two semicircular rings 21. The "fixed connection" between the outer arc-shaped fixing plate 32 and the two semicircular rings 21 can be any connection method commonly used in the art, such as bonding or screwing, so it will not be described in detail here.

[0037] As some preferred embodiments, see the appendix. Figure 3 As shown, the inner wall of the sleeve 2 is provided with an upper expanding annular groove 22 and a lower expanding annular groove 23, respectively; the two internally threaded rings 1 are respectively embedded in the upper expanding annular groove 22 and the lower expanding annular groove 23, and the inner arc-shaped clamping plate 31 is provided on the inner wall of the sleeve 2 between the upper expanding annular groove 22 and the lower expanding annular groove 23. This arrangement is beneficial for fixing the position of the two internally threaded rings 1 after the sleeve 2 is formed by connecting the two semi-circular rings 21 through the connector 3, thereby improving the connection stability between the reinforcing cages.

[0038] As some preferred embodiments, see the appendix. Figure 5 and attached Figure 6 As shown, the connector 3 also includes an upper vertical plate 34 and a lower vertical plate 35 disposed at the upper and lower ends of the inner arc-shaped clamping plate 31, an upper hanging plate 36 disposed on the upper vertical plate 34 and in contact with the lower groove wall of the upper expanded diameter annular groove 22, and a lower hanging plate 37 disposed on the lower vertical plate 35 and in contact with the upper groove wall of the lower expanded diameter annular groove 23.

[0039] The upper hanging plate 36 is arranged between the lower groove wall of the upper diameter expanding groove 22 and the lower surface of the inner threaded ring 1, and the lower hanging plate 37 is arranged between the upper groove wall of the lower diameter expanding groove 23 and the upper surface of the inner threaded ring 1. The thickness of the upper hanging plate 36 and the lower hanging plate 37 is less than or equal to 2 mm. With the arrangement of the upper hanging plate 36 and the lower hanging plate 37, the inner threaded ring 1 is pressed against the upper hanging plate 36 and the lower hanging plate 37 under the condition that the inner threaded ring 1 is limited by the upper diameter expanding groove 22 and the lower diameter expanding groove 23, so that the upper and lower sides of the connecting piece 3 are fixed sufficiently, and finally the connecting strength between the two half circular ring bodies 21 is improved. At the same time, the upper hanging plate 36 and the lower hanging plate 37 fill the gap between the upper diameter expanding groove 22, the lower diameter expanding groove 23 and the inner threaded ring 1, and strengthen the fixing effect of the inner threaded ring 1.

[0040] Preferably, the surfaces of the upper vertical plate 34 and the lower vertical plate 35 near the inner wall of the sleeve 2 are arc surfaces, and the upper hanging plate 36 and the lower hanging plate 37 are arc plates. This arrangement is conducive to improving the adhesion of the connecting piece 3 to the inner and outer walls of the two half circular ring bodies 21.

[0041] Preferably, the inner walls of the upper and lower ends of the sleeve 2 are provided with elastic layers 25 matched with the end threaded joints b. The material of the elastic layer 25 can be rubber or other commonly used materials in the art, which improves the fastening effect of the end threaded joints b and finally improves the connecting strength between the two reinforcement cages a.

[0042] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
