During the butt connection process of the end faces of the two sections of the precast concrete pile, the structural adhesive applied between the end faces of the precast concrete pile is squeezed and flows to the inner wall of the receiving groove, and the first skirt panel extension prevents the structural adhesive from flowing out. At the same time, the structural adhesive can overflow along the gap between the receiving groove and the second skirt panel to fill the gap between the first skirt panel and the second skirt panel ( Figure 6 The middle number 5 indicates the structural adhesive entering the gap between the two skirt plates), which increases the bonding area of the two sections of precast concrete piles, improves the connection strength of the precast concrete piles, and enhances the corrosion resistance of the pile connection.

During the butt connection process of the end faces of the two sections of the precast concrete pile, the structural adhesive applied between the end faces of the precast concrete pile is squeezed and flows to the inner wall of the receiving groove, and the first skirt extension prevents the structural adhesive from flowing out. At the same time, the structural adhesive can overflow along the gap between the receiving groove and the second skirt to fill the gap between the first skirt and the second skirt ( Figure 2 The middle number 5 indicates the structural adhesive entering the gap between the two skirt plates), which increases the bonding area of the two sections of precast concrete piles, improves the connection strength of the precast concrete piles, and enhances the corrosion resistance of the pile connection.

At the same time, the structural adhesive can overflow along the gap between the receiving groove and the second skirt board to fill the gap between the first skirt board and the second skirt board, thereby increasing the bonding area of the two sections of precast concrete piles, improving the connection strength of the precast concrete piles, and enhancing the corrosion resistance of the pile connection.
[0053] In other embodiments, Figure 2 and Figure 6As shown, one end of the second skirt board wrapping portion 20 close to the end of the precast concrete pile 4 shrinks toward the center direction of the second skirt board wrapping portion 20, so that the size of the one end of the second skirt board wrapping portion 20 close to the end of the precast concrete pile 4 is less than or equal to the size of the receiving groove 12 surrounded by the first skirt board extension portion 11; specifically, in this embodiment, the first skirt board is a tube structure matched with the size of one end of the precast concrete pile, the upper and lower sizes of the first skirt board are consistent, part of the length of the first skirt board is wrapped around the end of the precast concrete pile to form the first skirt board wrapping portion, the remaining part of the first skirt board extends out of the end of the precast concrete pile to form the first skirt board extension portion, and the area surrounded by the first skirt board extension portion forms a receiving groove, and the second skirt board is a tube structure matched with the other end of the precast concrete pile, the upper and lower sizes of the second skirt board are inconsistent, and one end of the second skirt board shrinks toward the center direction, so that one end of the second skirt board The size is smaller than that of the other end, that is, the size of one end of the second skirt board wrapping part 20 close to the end of the precast concrete pile 4 is smaller than or equal to the size of the receiving groove 12 surrounded by the first skirt board extension part 11, so that when two sections of precast concrete piles 4 are connected, the end of the precast concrete pile 4 provided with the second skirt board 2 can be inserted into the receiving groove 12 of the other precast concrete pile 4 provided with the first skirt board 1, so that during the end-to-end connection of the two sections of precast concrete piles, the structural adhesive coated between the end faces of the precast concrete piles is squeezed and flows to the inner wall of the receiving groove, and the first skirt board extension part prevents the structural adhesive from flowing out. At the same time, the structural adhesive can overflow along the gap between the receiving groove and the second skirt board to fill the gap between the first skirt board and the second skirt board, thereby increasing the bonding area of the two sections of precast concrete piles, improving the connection strength of the precast concrete piles, and enhancing the corrosion resistance of the pile connection.
[0054] In some other embodiments, such as Fig.15As shown, the first skirt board extension portion 11 expands outward from the connection with the first skirt board wrapping portion 10, so that the size of the end of the second skirt board wrapping portion 20 close to the end of the precast concrete pile 4 is less than or equal to the size of the receiving groove 12 surrounded by the first skirt board extension portion 11. Specifically, in this embodiment, the first skirt board is a pipe structure that matches the size of one end of the precast concrete pile, and the upper and lower sizes of the first skirt board are inconsistent. Part of the length of the first skirt board is wrapped around the end of the precast concrete pile to form the first skirt board wrapping portion, and the remaining part of the first skirt board extends out of the end of the precast concrete pile to form the first skirt board extension. The first skirt board extension portion 11 expands outward from the connection with the first skirt board wrapping portion 10, and the area surrounded by the first skirt board extension portion forms a receiving groove. The second skirt board is a pipe structure that matches the other end of the precast concrete pile. The upper and lower dimensions of the second skirt board are consistent, and the dimension of the second skirt board is less than or equal to the dimension of the receiving groove 12 formed by the extension portion 11 of the first skirt board, so that when two sections of precast concrete piles 4 are connected, the end portion of the precast concrete pile 4 provided with the second skirt board 2 can be inserted into the receiving groove 12 of one end of the other precast concrete pile 4 provided with the first skirt board 1, so that in the process of butting the end faces of the two sections of precast concrete piles, the structural adhesive coated between the end faces of the precast concrete piles is squeezed and flows to the inner wall of the receiving groove, and the extension portion of the first skirt board prevents the structural adhesive from flowing out. At the same time, the structural adhesive can overflow along the gap between the receiving groove and the second skirt board to fill the gap between the first skirt board and the second skirt board, thereby increasing the bonding area of the two sections of precast concrete piles, improving the connection strength of the precast concrete piles, and enhancing the corrosion resistance of the pile connection.
[0055] In some embodiments, the size difference between the end of the second skirt board wrapping portion 20 close to the end of the precast concrete pile 4 and the size of the receiving groove 12 surrounded by the first skirt board extension portion 11 is 1-5mm. By setting the size difference between the end of the second skirt board wrapping portion 20 close to the end of the precast concrete pile 4 and the size of the receiving groove 12 surrounded by the first skirt board extension portion 11 to 1-5mm, it can be better achieved that during the process of connecting the end faces of the two sections of precast concrete piles, the structural adhesive coated between the end faces of the precast concrete piles is squeezed and flows to the inner wall of the receiving groove, and fills the gap between the first skirt board and the second skirt board, thereby increasing the bonding area of the two sections of the precast concrete piles, improving the connection strength of the precast concrete piles, and enhancing the corrosion resistance of the pile connection.
[0056] Furthermore, in some embodiments, the first skirt extension 11 extends out of the end of the precast concrete pile 4 by 5-20 mm, which can better achieve that during the butt joint of the two precast concrete pile ends, the structural adhesive applied between the precast concrete pile ends is squeezed and flows to the inner wall of the receiving groove, and fills the gap between the first skirt and the second skirt, thereby increasing the bonding area of the two precast concrete piles, improving the connection strength of the precast concrete piles, and enhancing the corrosion resistance of the pile connection.

[0058] Specifically, in the figure, the number of connecting ear plates is 3, and the specific number can be set as needed. The connecting ear plate 2 includes an ear plate fixing portion 20 for fixedly connecting with the wrapping portion and an ear plate connecting portion 21 provided with a connecting hole 22. Specifically, the skirt plate disclosed in the present application can be used for concrete piles with an end plate structure, and can also be used for concrete piles without an end plate structure. When used for concrete piles with an end plate structure, the end of the annular portion of the skirt plate disclosed in the present application can be welded to the end plate as a whole. When the skirt plate disclosed in the present application is used for concrete piles without an end plate structure, the wrapping portion of the skirt plate disclosed in the present application is fixed with a connecting ear plate, and a connecting hole is provided on the ear plate connecting portion, which can be connected to the end nut (the ear plate connecting portion is arranged at the end of the end nut, and the connecting hole corresponds to the hole of the end nut, and components such as tensioning bolts can pass through the connecting hole and be connected to the end nut) to facilitate fixing the skirt plate.
[0059] Furthermore, if Figure 8 and Fig. 9 As shown, in some embodiments, one end of the second skirt board wrapping portion 20 close to the end of the precast concrete pile 4 is further provided with a bent edge 21 bent toward the center direction of the second skirt board wrapping portion 20 .
[0060] Specifically, by providing a bent edge 21 bent toward the center direction of the second skirt board wrapping portion 20 at one end of the second skirt board wrapping portion 20 close to the end of the precast concrete pile 4, the bent edge 21 can wrap the end of the precast concrete pile, thereby further improving the wrapping force between the skirt board and the precast concrete pile and the strength of the end of the precast concrete pile, thereby further reducing the deformation or damage caused by the end of the precast concrete pile being subjected to forces such as hammering.
[0061] Furthermore, if Fig.13 and Fig.14As shown, in some embodiments, the first skirt board wrapping portion 11 and / or the second skirt board wrapping portion 20 is further provided with a hoop 31 for increasing the wrapping force between the skirt board and the precast concrete pile.
[0062] Specifically, by providing a hoop on the skirt board wrapping part, the wrapping force between the skirt board and the end of the precast concrete pile can be further improved, the strength of the end of the precast concrete pile can be improved, and the end of the concrete pile is not easily damaged. In this embodiment, the hoop 31 can be a steel plate formed into a specific shape by rolling, and the rolled steel plate is formed to form a skirt board structure. The shape of the hoop can be a continuous or discontinuous groove structure such as an arc, a triangle, a spiral groove, and a trapezoid.

[0063] Furthermore, the first skirt board and the second skirt board are square skirt boards, circular skirt boards or polygonal skirt boards to adapt to precast concrete piles of different pile types. At the same time, the size of the end of the second skirt board wrapping part close to the end of the precast concrete pile is less than or equal to the size of the receiving groove surrounded by the first skirt board extension part, so that when two sections of precast concrete piles are connected, the end of the precast concrete pile provided with the second skirt board can be inserted into the receiving groove of the end of the other precast concrete pile provided with the first skirt board. The method can be combined with different forms of skirt boards, for example, Fig.16 The figure shows a structural diagram of another embodiment of the skirt plate assembly disclosed in the utility model. The skirt plate in the figure is a square skirt plate for a square pile end. The upper and lower dimensions of the first skirt plate are consistent, and the upper and lower dimensions of the second skirt plate are consistent. The dimension of the second skirt plate is smaller than that of the first skirt plate, that is, the two ends of the precast concrete pile are inconsistent in size, so that the small end can be inserted into the receiving groove formed by the skirt plate at the large end; Fig.17 It is a structural diagram of another embodiment of the skirt board assembly disclosed in the utility model, in which the skirt board is a square skirt board for a square pile end, the upper and lower dimensions of the first skirt board are consistent, the upper and lower dimensions of the second skirt board are consistent, the dimension of the second skirt board is smaller than the dimension of the first skirt board, and a bent edge is provided on the second skirt board to further improve the strength of the pile end; Fig.18 This is a structural diagram of an embodiment of a skirt assembly disclosed in the utility model.
