[0002] The retaining wall structure of large diameter circular coal bunker is an important component to ensure the stability and safety of the coal bunker. This retaining wall structure usually has two main forms: a separate coal retaining wall structure and an integral coal retaining wall structure.

[0003] The existing large diameter circular coal bunker faces many challenges in open-air environments, especially in complex weather conditions such as strong winds, rain, and snow. These environmental factors not only have a direct impact on the steel structure of the coal bunker, but also can lead to a decrease in the performance of the coal bunker during use.

[0004] A key problem is that when coal is accumulated in the coal bunker, the load borne by the top of the retaining wall will significantly increase. To cope with this increased load, flexible steel strands are usually added to the top of the retaining wall structure to provide additional support. However, due to the adverse effects of the open-air environment, such as long-term sun and rain, temperature changes, and corrosion, the steel properties of the flexible steel strands gradually deteriorate, thereby reducing their support effect.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. Embodiment one

[0022] Please refer to Figures 1-4 The utility model provides the following technical scheme: a large-diameter circular coal bunker retaining wall structure, including coal retaining wall 1, buttress column 2 and foundation base 3, buttress column 2 is located at the outer side wall connection of coal retaining wall 1, foundation base 3 is located at the bottom end outer side wall connection of coal retaining wall 1, coal retaining wall 1 is circular, and buttress column 2 is distributed in the outer side wall of coal retaining wall 1 in the form of circular whole line, the top end of foundation base 3 is connected with round limiting block 4, a group of drainage holes 5 are opened in the surface of round limiting block 4 in the form of circular whole line, water collecting tank 12 is left between round limiting block 4 and coal retaining wall 1, the outer side wall of flexible steel beam 6 is connected in sequence through buttress column 2 and is connected with protective cover 7.

[0023] In the preferred embodiment, the outer side wall of coal retaining wall 1 is provided with mounting grooves 9 of the same number as buttress column 2, and the mounting grooves 9 are opened in the form of "convex" character.

[0024] In the preferred embodiment, buttress column 2 is inserted into the outer side wall of coal retaining wall 1 through mounting grooves 9, and the bottom end of buttress column 2 is connected in the water collecting tank 12.

[0025] In the embodiment, first, the retaining wall structure of the large-diameter circular coal bunker is composed of three components of coal retaining wall 1, buttress column 2 and foundation base 3. The large-diameter refers to a larger circular coal bunker, and coal is placed in the internal space of coal retaining wall 1. Buttress column 2 is installed in mounting grooves 9 in the form of insertion, and the bottom end is stably fixed in water collecting tank 12 between coal retaining wall 1 and round limiting block 4. This structure cooperates with foundation base 3 to form a stable support system of coal retaining wall 1.

[0026] The water collecting tank 12 has a certain depth due to the setting of the circular limiting block 4, which is designed to better collect and contain water. At the same time, the circular limiting block 4 is ingeniously provided with drainage holes 5, which are staggered with the positions of the buttress columns 2 to avoid interference with each other. Such design enables the water collecting tank 12 to quickly collect and discharge water when the large-diameter circular coal bunker retaining wall structure encounters rainy weather, effectively preventing water from remaining and reducing the corrosion risk to the outer side wall of the coal retaining wall 1. Example two

[0027] Please refer to Figures 1-4 , the flexible steel beam 6 is circular and connected to the outer side wall of the coal retaining wall 1.

[0028] In the preferred embodiment: the protective cover 7 is made of flexible metal material and is in the shape of a "Fang" character, and the protective cover 7 is in sealing connection with the outer side wall of the coal retaining wall 1.

[0029] In the preferred embodiment: the bottom end of the flexible steel beam 6 is provided with a support block 8, and the two ends of the support block 8 are connected to the side walls corresponding to the two buttress columns 2.

[0030] In the preferred embodiment: the side wall of the buttress column 2 is provided with a fixed plate 10, the top end of the fixed plate 10 is connected with a bolt 11, and the bolt 11 is threadedly connected with the protective cover 7 through the fixed plate 10.

[0031] In the example, considering that the coal placed in the coal retaining wall 1 will increase the load borne by the top end, in order to enhance the supporting performance of the coal retaining wall 1, we adopt the design that the flexible steel beam 6 passes through the buttress column 2 and is connected with the coal retaining wall 1. However, considering that the use environment of the large-diameter circular coal bunker retaining wall structure is very complex and changeable, we specially install the protective cover 7 on the outer surface of the flexible steel beam 6.

[0032] The bottom end of the protective cover 7 is stably placed on the support block 8, thereby realizing the overall covering of the flexible steel beam 6. Then, by rotating the bolt 11 to pass through the fixed plate 10 and tightly connect with the protective cover 7, we complete the installation of the protective cover 7. This carefully designed protective measure greatly reduces the gradual decline of the steel strength of the flexible steel beam 6 due to the invasion of adverse weather conditions such as strong wind, rain and snow.

[0033] Overall, this innovative design not only significantly improves the overall durability of the large-diameter circular coal bunker retaining wall structure, but also provides strong protection for its long-term stable operation in complex and changeable environments.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
