The steel sheet pile 1 includes a first wing plate 12, a rib plate and a second wing plate 13 connected in sequence, including: a support frame 2, a guide plate 3 and a fixing member 4; the guide plate 3 is arranged on one side of the support frame 2, and the guide plate 3 is arranged close to the side of the steel sheet pile 1. There are multiple guide plates 3, and they are arranged at intervals along the length direction of the support frame 2. A stable cavity 31 is formed between two adjacent guide plates 3. The length of the guide plate 3 is arranged along the vertical direction, and one side of the rib plate is suitable for fitting with the guide plate 3; the fixing member 4 is arranged on the other side of the support frame 2, and the fixing member 4 is arranged away from the side of the steel sheet pile 1. The fixing member 4 is inserted into the ground to fix the support frame 2 at a preset position.

[0035] Specifically, a guide plate 3 is arranged on one side of the support frame 2. A plurality of guide plates 3 are arranged and are arranged at intervals along the length of the support frame 2. A stabilizing cavity 31 is formed between two adjacent guide plates 3. After the fixing member 4 is inserted into the ground, soil enters the stabilizing cavity 31 to form a horizontal supporting force for the guide plate 3. The length of the guide plate 3 is arranged in the vertical direction, and one side of the rib plate is suitable for fitting and abutting against the guide plate 3. When installing the steel sheet pile 1, the support frame 2 is fixed by the arrangement of the stabilizing cavity 31 and the fixing member 4, so as to avoid deformation or distortion of the guide plate 3 under a large impact force, which affects the guiding installation of the steel sheet pile 1.

[0036] It can be understood that the steel sheet pile 1 is a Larsen steel sheet pile 1, which is provided with a rib plate, and a first wing plate 12 and a second wing plate 13 are provided on both sides of the rib plate.

[0037] Reference Figure 2 and Figure 3 As shown, in the embodiment of the first aspect of the present invention, the support frame 2 is an I-shaped structure, and the support frame 2 includes a web 21 and a third wing plate 22 and a fourth wing plate 23 respectively arranged on both sides of the web 21, the guide plate 3 is connected to the side of the third wing plate 22 close to the steel sheet pile 1, the fixing part 4 is arranged at the bottom of the fourth wing plate 23, and the web 21 is arranged horizontally.

[0046] Reference Figure 5 As shown, in the embodiment of the first aspect of the present invention, the fixing member 4 includes a latch portion 41 and a support portion 42. The latch portion 41 is triangular in shape with the tip facing downward, the latch portion 41 is connected to the lower end surface of the fourth wing plate 23, the support portion 42 is a conical structure, the support portion 42 is connected to the lower side surface of the web 21, the support portion 42 is connected to the latch portion 41, and the tip of the support portion 42 extends to be flush with the tip of the latch portion 41.

[0047] In the first embodiment of the present invention, a plurality of fixing members 4 are provided and are spaced apart along the length direction of the supporting frame 2 , and the center of the fixing member 4 is arranged opposite to the guide plate 3 .

[0048] Specifically, the setting of the fixing member 4 improves the installation stability of the support frame 2 and avoids excessive force during the tamping process of the support frame 2, which causes the support frame 2 to slip, so as to ensure the accuracy of the guiding precision.

[0049] In a second aspect, the present invention also provides a construction method for installing a steel sheet pile 1, comprising the following steps:

[0050] Remove the loose soil on the ground surface, and determine the installation position of the guide device of the steel sheet pile 1 according to the size of the steel sheet pile 1 and the pre-installation route;

[0051] Ramming the supporting frame 2 so that the fixing member 4 is inserted into the ground and the web 21 reaches the stable soil layer;

[0053] After the installation is completed, the soil is excavated to the position of the web 21, and the guide device of the steel sheet pile 1 is pushed out by the ejection device.

[0054] Specifically, by applying the guide structure of the steel sheet pile 1, the installation of the steel sheet pile 1 is achieved, which avoids the deformation or distortion of the guide structure under the action of a large impact force, thereby preventing the installation accuracy of the steel sheet pile 1 from being affected.

[0055] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
