[0026] The following further elaborates on the standardized retaining wall for tower crane foundations proposed by the present utility model in conjunction with the attached drawings and specific embodiments. According to the following description and claims, the advantages and features of the present utility model will become clearer. It should be noted that the attached drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present utility model.

[0027] Please refer to Figures 1 to 3 , the standardized retaining wall for tower crane foundations includes: a rectangular steel frame 1, four enclosing plates 2, and four triangular brackets 3. The cross-section of the rectangular steel frame 1 is larger than the cross-section of the tower crane foundation 100. A triangular bracket 3 is welded in the frame of each side of the rectangular steel frame 1, and an enclosing plate 2 is welded on the outer surface of each side. In this embodiment, each enclosing plate 2 is a pattern steel plate; the rectangular steel frame 1 is made of I-beams as materials. I-beams are easy to cut and weld, and the length of the I-beams can be adjusted according to one's own needs.

[0028] The standardized retaining wall for tower crane foundations of the present utility model is composed of a steel frame and a pattern steel plate enclosure to form a retaining wall. Through the means of standardized production, it replaces the traditional on-site masonry method to achieve the goals of safety, economy, and environmental protection, and effectively improves the construction efficiency.

[0029] As Figure 3 shown, considering the instability of the rectangular structure, a triangle is provided on each of the four sides of the rectangular steel frame 1, thereby enhancing the structural stability and longitudinal stiffness of the standardized retaining wall for tower crane foundations. In this implementation, each triangular bracket 3 includes: two I-beam braces and one I-beam crossbeam, and the three together enclose a triangle.

[0030] Please refer to Figure 2 , the standardized retaining wall for tower crane foundations further includes four keels 4, which are longitudinally arranged inside the rectangular steel frame 1, and each keel 4 is arranged at the middle position of one inner side of the rectangular steel frame 1. In this embodiment, each keel 4 is an I-beam.

[0031] To further enhance the structural stability and lateral stiffness, a support is added to each of the four corners of the top surface and the ground of the standardized retaining wall for tower crane foundations. Specifically, as Figure 2 shown, the standardized retaining wall for tower crane foundations further includes: four top surface diagonal braces 5, which are arranged on the top surface of the rectangular steel frame 1, and each top surface diagonal brace 5 forms a triangle with each corner of the top surface respectively. Preferably, each top surface diagonal brace 5 is an I-beam.

[0032] Preferably, the standardized retaining wall for the tower crane foundation further includes: four bottom diagonal braces disposed on the bottom surface of the rectangular steel frame 1, and each top diagonal brace 5 and each corner of the bottom surface form a triangle respectively. Preferably, each bottom diagonal brace is an I-beam.

[0033] In this embodiment, please refer to Figure 1 , the rectangular steel frame 1 and the other components are all connected by high-strength bolts so as to disassemble the standardized components into small units for easy transportation; in later optimization, some small units can be welded to increase integrity and strength. The connection between the standardized retaining wall for the tower crane foundation and the tower crane foundation 100 adopts expansion bolts to prevent side shift due to uneven stress on all sides during the filling process.

[0034] For the I-beam specifications, steel plate thickness, and high-strength bolt strength of the standardized retaining wall, they are all determined through bearing capacity calculation. The overall dimensions of the standardized retaining wall are determined by investigating the dimensions of a large number of tower crane foundations and tower crane standard sections to enhance subsequent versatility.

[0035] In this embodiment, 16# I-beams are used, the steel plate thickness is 3 mm, and the distance between the diagonal braces on the top and bottom surfaces and the tower crane foundation should be greater than or equal to 300 mm.

[0036] It can be understood that the above examples are only examples listed for better understanding of the technical solutions of the embodiments of the present application and do not serve as the sole limitation to this embodiment.

[0037] Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily essential to the present application.
