[0003] Currently, this type of precast concrete pile is widely used in foundation pit maintenance and slope stabilization projects. However, existing I-shaped support piles have the following shortcomings during construction and use: 1. During the pile sinking process, adjacent piles are connected by inserting the upper and lower wing plates of the support piles to achieve docking, which requires high pile processing precision and is also difficult to construct. 2. Existing I-shaped support piles often crack during sinking and subsequent use, affecting the water-retaining properties and strength of the piles. 3. The water-retaining surface of existing support piles has low impact resistance. These technical issues urgently need to be addressed by those skilled in the art. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0033] Example 1:

[0034] like Figure 1-2 As shown, the utility model provides an assembled water conservancy prefabricated I-shaped support pile, including a pile body, which is a reinforced concrete prefabricated pile;

[0035] The cross section of the pile body includes a first wing plate 1, a web plate 2 and a second wing plate 3. The first wing plate 1 and the second wing plate 3 are arranged parallel to each other.

[0036] The web 2 is arranged between the first wing 1 and the second wing 3, and the first wing 1, the web 2 and the second wing 3 are in an I-shape;

[0037] The transverse width of the first wing plate 1 is smaller than the transverse width of the second wing plate 3, and both ends of the first wing plate 1 and the second wing plate 3 are symmetrical relative to the central axis of the pile body;

[0038] Symmetrical arc-shaped bodies 21 are provided on both sides of the web 2, and the arc-shaped bodies 21 extend from the end of the first wing plate 1 to the second wing plate 3;

[0039] A first convex portion 31 and a first concave portion 32 matching each other are formed at both ends of the cross section of the second wing plate 3;

[0040] The working principle and beneficial effects of the above embodiment are as follows:

[0041] When using, such as Figure 3 As shown, multiple piles are inserted into the foundation, and adjacent piles are butted against each other. By designing the transverse width of the first wing plate 1 to be smaller than the transverse width of the second wing plate 3, when the piles are arranged, the first convex portions 31 and the first concave portions 32 at both ends of the adjacent second wing plates 3 are engaged and connected, thereby reducing the construction difficulty and increasing the water-stopping performance of the piles. The arc-shaped bodies 21 on both sides of the web 2 extend from the end of the first wing plate 1 to the second wing plate 3, thereby improving the connection strength between the web 2 and the first wing plate 1 and the second wing plate 3, increasing its contact surface with the foundation pit, and having strong anti-support force, which can avoid stress concentration and cracking during piling. At the same time, the arc-shaped bodies 21 play the role of diversion and buffering, reducing the impact force of water flow on the pile body.

[0042] The I-shaped support pile of the utility model has better mechanical properties than the traditional support pile. At the same time, its cross-sectional area is small, which can reduce the amount of concrete used and greatly reduce the manufacturing cost.

[0043] Example 2:

[0044] The other parts are the same as those in the first embodiment. Figure 4-5 As shown, in addition to the lateral width of the second wing plate 3 being twice that of the first wing plate 1 , a second convex portion 11 and a second concave portion 12 matching each other are formed at both ends of the cross section of the first wing plate 1 ;

[0045] The working principle and beneficial effects of the above embodiment are as follows:

[0046] When using, such as Figure 6 As shown, adjacent piles are arranged in a staggered manner, with the preceding pile engaging with the following pile, i.e., the second convex portion 11 engages with the first concave portion 32, and the first convex portion 31 engages with the second concave portion 12, forming a staggered structure, which enhances the overall bending stiffness and lateral resistance, and improves the support effect.

[0047] In one embodiment,

[0048] An upwardly inclined slope 33 is formed on the second wing plate 3 , and an end of the slope 33 is connected to the arc-shaped body 21 , thereby further enhancing the structural strength of the second wing plate 3 .

[0049] In one embodiment,

[0050] The cross-sectional shape of the first protrusion 31 and the first recess 32 is any one of an arc, a trapezoid, a triangle or a U-shaped shape.

[0051] The corresponding cross-sectional structures of the first convex portion 31 and the first concave portion 32 are selected based on the convenience of installation and water-stopping performance between the pile bodies.

[0052] In one embodiment,

[0053] The cross-sectional shapes of the first convex portion 31 and the second concave portion 12 match each other, and the cross-sectional shapes of the second convex portion 11 and the first concave portion 32 match each other;

[0054] In one embodiment,

[0055] like Figure 7 As shown, a plurality of main bars and stirrups are provided inside the pile body. The main bars extend along the length direction of the pile body. Two rows of main bars are arranged in the first wing plate 1 and the second wing plate 3 to enhance the structural strength of the first wing plate 1 and the second wing plate 3, thereby improving their unilateral bending resistance and obtaining a greater bearing capacity.

[0056] In one embodiment,

[0057] The cross-sections of the first wing panel 1 and the second wing panel 3 are rectangular. Hanging bars are pre-embedded on the first wing panel 1 to facilitate later construction operations. The number of the hanging bars is at least two.

[0058] Construction method:

[0059] First, the I-shaped support pile is lifted vertically and steadily by the lifting rod, and the lifted support pile is inserted into the predetermined pile position. After the support pile is inserted and installed, it needs to be leveled to ensure that its horizontality meets the construction requirements. At the same time, its verticality needs to be adjusted to ensure that the support pile is vertical; during the construction process, it is necessary to monitor and adjust the horizontality and verticality of the support pile at any time. When the support pile reaches the designed depth, the pile sinking construction is completed; by sinking the support piles one by one in parallel or staggered, a continuous pile wall is eventually formed to provide the necessary support and stability effects.

[0060] In summary:

[0061] The utility model discloses an assembled hydraulic prefabricated I-shaped support pile. By designing the transverse width of the first wing plate to be smaller than the transverse width of the second wing plate, when the pile bodies are arranged, the first convex portions and the first concave portions at both ends of adjacent second wing plates are engaged and connected, thereby reducing the construction difficulty and improving the water-stopping performance of the pile body.

[0062] The arc-shaped bodies on both sides of the web of the utility model extend from the end of the first wing plate to the second wing plate, thereby improving the connection strength between the web and the first and second wing plates, increasing the contact surface between the web and the foundation pit, and providing strong anti-supporting force, thereby avoiding stress concentration and cracking during pile driving; at the same time, the arc-shaped bodies play a role of diversion and buffering, reducing the impact force of water flow on the pile body;

[0063] The mechanical properties of the I-shaped support pile of the utility model are superior to those of the traditional support pile. At the same time, its small cross-sectional area can reduce the amount of concrete used and greatly reduce the manufacturing cost.

[0064] When arranging the pile bodies of the utility model, a suitable pile sinking method is selected according to the requirements of on-site construction and support effect, and the pile bodies are spliced side by side or staggered into rows.
