[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0026] like Figure 1 As shown, the rounded T-shaped reinforced concrete sheet pile includes an arc-shaped web 1 and a transverse flange 2. The arc-shaped web 1 is a continuous arc segment or a semi-circular arc, and the arc-shaped web 1 extends along the axis of the pile body. The transverse flange 2 is arranged perpendicular to the arc-shaped web 1 and extends along the axis of the pile body. The flange surface of the transverse flange 2 opposite to the web is a plane.

[0027] The rounded T-shaped sheet pile structure can be a reinforced concrete structure or a prestressed reinforced concrete structure.

[0028] Depending on the construction conditions, the rounded T-shaped sheet pile can be configured as a solid structure. Alternatively, it can have an arc-shaped cavity 10 in the arc-shaped web that matches the shape of the arc-shaped web. This cavity 10 extends from top to bottom with a uniform cross-section along the axis of the pile body, allowing the rounded T-shaped sheet pile to save materials while meeting strength requirements.

[0029] The transverse flange 2 of the rounded T-shaped sheet pile is straight. The transverse flanges of adjacent T-shaped sheet piles are connected by different waterproofing methods, namely grouting connection 3 or tenon connection 4.

[0030] After the flanges of the rounded T-shaped sheet piles are connected, the riverbank lines are all straight sections, which is used to ensure the smoothness of the water flow.

[0031] The rounded T-shaped sheet pile can be fitted with drainage holes as needed to facilitate drainage.

[0032] The rounded T-shaped sheet pile can be equipped with several grouting pipes evenly embedded in the pile body according to actual needs, so as to inject cement grout with appropriate ratio and material at the pile end, which can reduce the difficulty of pile driving construction.

[0033] Preferably, when the arc-shaped web of the round T-shaped sheet pile is arranged on the water side, a wood grain effect is added by the mold, which not only enhances the ecological effect, but also realizes the wood grain effect by the mold without increasing the production process and additional manufacturing cost, and is simple to manufacture and has good ecological effect.

[0034] The cavity structure inside the round T-shaped sheet pile can also be arranged in another way. As shown in Figure 2 the cavity 11 is arranged in the arc-shaped web of the pile body and has the same shape as the arc-shaped web, the cavity 11 extends from top to bottom along the axis of the pile body and the cross-sectional area continuously decreases, and the cavity bottom is reduced to 0 before extending to the bottom edge of the pile structure, and the cavity bottom is left with a pile end protection thickness of about 200 mm. In production and processing, a fiber reinforced material or a thin steel plate is used to form a mold plate of the cavity 11. After the round T-shaped sheet pile is poured and formed, the mold plate of the cavity 11 can also be retained in the pile body according to the design requirements, which is used as a stiffening structure to play a structural reinforcement role. The arrangement of the cavity 11 can save materials while meeting the strength requirements, and make the stress of the pile structure along the axis of the pile body meet the requirements of soil pressure distribution.

[0035] The cavity structure inside the round T-shaped sheet pile can also be arranged in another way. As shown in Figure 3 the cavity 11 is arranged in the arc-shaped web of the pile body and has the same shape as the arc-shaped web, the cavity 11 extends from top to bottom along the axis of the pile body and the cross-sectional area continuously decreases, and the cavity bottom is reduced to 0 before extending to the bottom edge of the pile structure, and the cavity bottom is left with a pile end protection thickness of about 200 mm. In production and processing, a fiber reinforced material or a thin steel plate is used to form a mold plate of the cavity 11. After the round T-shaped sheet pile is poured and formed, the mold plate of the cavity 11 can also be retained in the pile body according to the design requirements, which is used as a stiffening structure to play a structural reinforcement role. The arrangement of the cavity 11 can save materials while meeting the strength requirements, and make the stress of the pile structure along the axis of the pile body meet the requirements of soil pressure distribution.

[0036] In production and processing, a fiber reinforced material or a thin steel plate is first prefabricated into a hollow shell that surrounds the cavity 21, and then the shell is fixed as a mold plate in the mold plate of the round T-shaped sheet pile according to the cavity position, and then the reinforcement is bound and poured and formed. The shell of the cavity 21 is arranged in the pile body as a reinforcing structure after the round T-shaped sheet pile is poured and formed, which not only forms a cavity structure, but also plays a role of stiffening and structural reinforcement. The upper part of the pile structure of the cavity 21 is a solid structure, which can ensure that the strength of the pile head is not weakened during construction, thereby ensuring the construction quality. The lower part of the pile structure of the cavity 21 is a solid structure, which can ensure that the strength of the pile tip is not weakened during construction, thereby ensuring the construction quality, and also can realize the required strength of the pile body under strong soil pressure.

[0037] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
