Abstract
Description
Technical Field
[0001] The present application relates to the technical field of retaining wall structures, and in particular to a wear-resistant retaining wall. Background Art
[0002] In blast furnace production, the granulated slag steam tower plays the role of buffering the granulated slag water of the blast furnace and collecting steam. The steam tower is cast in concrete as a whole, and a retaining wall is set on the surface of the steam tower. The slag water has a high temperature and is corrosive, generally exceeding 80°C, and occasionally large pieces of red slag are mixed in it. During the production process, the contact area between the retaining wall and the slag water is very easy to be worn by the slag and blocky red slag in the slag water. Wear-resistant alloy materials have been used to make retaining walls, which are costly and the installation parts are easily corroded by slag water. The gaps are also easily washed away by slag water. Once the gaps expand, they are easily swollen and collapsed by slag water. Wear-resistant materials such as cast stone slabs have also been pasted on the surface of the retaining walls, but they are also very easy to fall off due to the large temperature difference of the slag water. Therefore, the wear resistance of the retaining walls is currently poor and the repair frequency is high. Summary of the invention
[0003] The purpose of the embodiments of the present application is to provide a wear-resistant retaining wall, which can solve the technical problems of poor wear resistance and high repair frequency of the current retaining wall.
[0004] An embodiment of the present application provides a wear-resistant retaining wall, including a concrete layer, on which a plurality of rows of wear-resistant components are embedded in sequence from top to bottom, the wear-resistant components are arranged obliquely, and the wear-resistant components include a plurality of cast stone plates, and the cast stone plates are arranged in an overlapping manner in a fish scale shape.
[0005] Wherein, the inclination angle of the wear-resistant component is greater than 100°.
[0006] Wherein, the overlapping area of adjacent overlapping cast stone plates is not less than 2 / 3.
[0007] Wherein, the concrete layer and the wear-resistant component are cast in one piece.
[0008] Wherein, the distance between two adjacent rows of the wear-resistant components is 40-80 mm.
[0009] The area of the cast stone plate is 12 to 20 dm 2 .
[0010] Wherein, the thickness of the cast stone plate is 20 to 40 mm.
[0011] Beneficial effects of the utility model:
[0012] The utility model provides a wear-resistant retaining wall. When in use, the wear-resistant retaining wall is arranged on the surface of a steam tower body. A cast stone plate with low manufacturing cost and excellent wear resistance is used as the wear-resistant main material of the retaining wall. The cast stone plate and concrete are combined into one by an inlaid casting method, so that the cast stone plate is not easy to fall off and the production cost is low; the arrangement angle of the cast stone plate is designed according to the scouring angle of slag water to form a certain inclination angle, so that the folded splash water flow formed by the slag water when scouring the retaining wall is not easy to be secondary scoured to the overlapping inside of the cast stone plate, further ensuring that the cast stone plate is firmly and stably inlaid; in order to prevent the gaps of the cast stone plates from being exposed to the outside, a multi-layer staggered and overlapping fish-scale arrangement layout is adopted to ensure that the upper cast stone plate can effectively cover the joint gaps of the lower cast stone plate, so that only a small part of the joint gaps is exposed to the outside, preventing the gaps of the cast stone plates from being directly eroded by slag water, thereby improving the wear resistance of the retaining wall and reducing the repair frequency.

[0026] like Figure 1 and 2 As shown, an embodiment of the present application provides a wear-resistant retaining wall, including a concrete layer 1, on which multiple rows of wear-resistant components 2 are embedded in sequence from top to bottom. The wear-resistant components 2 are arranged obliquely, and the wear-resistant components 2 include multiple cast stone plates 21, and the cast stone plates 21 are arranged in an overlapping manner in a fish scale shape.
[0027] When in use, a wear-resistant retaining wall is set on the surface of the steam tower body 3, and a cast stone plate 21 with low manufacturing cost and excellent wear resistance is used as the wear-resistant main material of the retaining wall. The cast stone plate 21 and concrete are combined into one by an inlaid casting method, so that the cast stone plate 21 is not easy to fall off and the production cost is low; the arrangement angle of the cast stone plate 21 is designed according to the slag water scouring angle to form a certain inclination angle, so that the splashing water flow formed by the slag water when scouring the retaining wall is not easy to be secondary scoured to the overlapping interior of the cast stone plate 21, further ensuring that the cast stone plate 21 is firmly and stably inlaid; in order to prevent the gaps of the cast stone plates 21 from being exposed to the outside, a multi-layer staggered and overlapping fish-scale arrangement layout is adopted to ensure that the upper cast stone plate 21 can effectively cover the joint gaps of the lower cast stone plate 21, so that only a small part of the joint gaps are exposed to the outside, preventing the gaps of the cast stone plates 21 from being directly eroded by slag water, thereby improving the wear resistance of the retaining wall and reducing the repair frequency.
[0028] like Figure 1 and 2 As shown, in this embodiment, the inclination angle of the wear-resistant component 2 is greater than 100°; the arrangement angle of the cast stone plate 21 is designed according to the scouring angle of the slag water, forming a certain inclination angle, so that the splashing water flow formed by the slag water when scouring the retaining wall is not easy to be flushed to the overlapping interior of the cast stone plate 21 for the second time, further ensuring that the cast stone plate 21 is firmly and stably embedded.
[0029] like Figure 1 and 2 As shown, in this embodiment, the overlapping area of adjacent overlapping cast stone plates 21 is not less than 2 / 3, ensuring that even if the slag water scours and erodes the concrete layer 1, the cast stone plates 21 have sufficient embedding thickness in the concrete layer 1 and will not fall off easily.
[0030] In this embodiment, the concrete layer 1 and the wear-resistant component 2 are cast and formed as one body, so that the cast stone plate 21 is not easy to fall off.
[0031] In this embodiment, the distance between two adjacent rows of wear-resistant components 2 is 40-80 mm; specifically, 60 mm is preferred.
[0032] In this embodiment, the area of the cast stone plate 21 is 12 to 20 dm 2 .
[0033] In this embodiment, the thickness of the cast stone plate 21 is 20-40 mm.
[0034] Specifically, the size of the cast stone plate 21 may preferably be 400 mm*400 mm*30 mm.
[0035] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. 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.
