[0002] Retaining walls, as important supporting structures for roadbeds and hillside soil, play a vital role in ensuring the safety and stability of embankments and lines. In various engineering projects, common retaining wall forms include buttress type, gravity type and anchor type, each of which plays a key protective role in different engineering environments. However, these traditional retaining wall structures generally face some technical challenges, such as limited bearing capacity, long construction period, and significant impact on the surrounding environment. These problems not only affect the efficiency and quality of the project, but also restrict the further development of retaining wall technology.

[0003] In recent years, with the construction industry's pursuit of efficient and environmentally friendly construction technology, prefabricated concrete buildings have been vigorously promoted and applied. Precast concrete technology, with its efficient production methods, reliable quality assurance, and environmental protection and energy-saving characteristics, has become the focus of technological innovation in the construction field. The widespread application of this technology has not only improved the construction efficiency of construction projects, but also significantly reduced the impact on the surrounding environment, demonstrating its great potential in modern engineering construction.

[0004] Given the many advantages of precast concrete technology, applying it to the field of retaining wall structures to realize the production and installation of prefabricated retaining walls is undoubtedly a technical direction worth exploring. Through precast concrete components, we can achieve standardized and modular production of retaining walls, thereby simplifying the production process and improving construction efficiency. At the same time, the installation process of prefabricated retaining walls is also relatively fast, greatly shortening the project cycle. In addition, since the quality of precast concrete components is controllable, the force performance of prefabricated retaining walls is also more reliable, which can effectively improve the bearing capacity and stability of retaining structures.

[0005] In summary, the application of precast concrete technology in the field of retaining wall structures is expected to promote the innovation and development of retaining wall technology and provide more efficient, environmentally friendly and reliable solutions for engineering construction.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figures 1 to 4 As shown, the utility model provides an assembled retaining wall structure, including

[0029] 1. An assembled retaining wall structure, characterized by comprising:

[0030] The L-shaped wall 1 and the base 2; wherein the L-shaped wall 1 is integrally formed by a bottom plate 11 and a baffle 12 and is fixed on the base 2 through an assembled anchoring assembly 3 .

[0031] It should be noted that the reason for setting up the L-shaped wall 1 is to effectively block the movement of soil and rocks and protect the safety of the surrounding environment; at the same time, the integrated bottom plate 11 and baffle 12 can better disperse the soil pressure and improve the bearing capacity of the wall.

[0032] Preferably, the assembled anchor assembly 3 includes a metal bellows 31 and a bolt 32;

[0033] The metal bellows 31 is pre-buried on the bottom plate 11; one end of the bolt 32 is pre-buried in the base 2, and the other end extends out of the surface of the base 2, and its extension height is not greater than the height of the bottom plate 11; the bolt 32 is inserted into the metal bellows 31 and anchored by pouring grouting material. It should be noted that the reason for using the metal bellows 31 and the bolt 32 as the anchoring assembly is its high strength and corrosion resistance. The metal bellows 31 can effectively disperse the stress of the bolts 32 to prevent the L-shaped wall 1 from loosening or shifting during the installation process, and the bolts 32 can tightly connect the L-shaped wall 1 to the base 2 to ensure its stability. In addition, the grouting material can fill the gap between the bolts and the metal bellows to form a solid overall structure; the reason for anchoring by inserting the bolts 32 and pouring the grouting material is that it can provide additional fixing force to ensure that the connection between the L-shaped wall 1 and the base 2 is more firm and reliable, and this combined design makes installation more convenient; wherein, the bolts 32 can be made of corrosion-resistant materials, and their surfaces may be specially treated, such as galvanizing or spraying anti-corrosion paint, to increase their service life.

[0034] Specifically, a limiting structure 22 is further provided on the base 2, which is integrally formed with the base 2 and fits with the baffle 12 to hold the L-shaped wall 1. It should be noted that the limiting structure 22 can be a rectangular baffle or a right-angled triangle baffle; the reason for providing the limiting structure 22 is that it can provide additional support and fixing to ensure that the L-shaped wall 1 can remain stable when subjected to soil pressure or other external forces.

[0035] Preferably, the upper surface edge of the bottom plate 11 and the bottom edge of the baffle 12 intersect at a certain angle to form a non-vertical transition surface 13. It should be noted that the reason for setting the non-vertical transition surface is that it can disperse the impact force of the soil on the wall and reduce the stress concentration on the L-shaped wall 1.

[0036] Furthermore, a sealing material is provided between the L-shaped wall 1 and the foundation base 2 to enhance the sealing between the L-shaped wall 1 and the foundation base 2, thereby preventing water or other liquids from seeping in from the gap between the L-shaped wall 1 and the foundation base 2, thereby further ensuring the stability and durability of the retaining wall structure; the space on one side of the baffle 12 of the L-shaped wall 1 relative to the limiting structure 22 is used for filling, and the height and width of the baffle 12 match the filling thickness and height required by the engineering design, thereby receiving and stably supporting the filled soil.

[0037] Example 2

[0038] Based on Example 1, this embodiment also provides an assembled anchoring assembly, which includes a steel cage embedded in the foundation base 2 instead of the bolts 32 in the embodiment; a port at one end of the steel cage that is flush with the foundation base 2 is provided with a plurality of steel bars extending out of the surface of the foundation base 2, and the extending height thereof is not greater than the height of the base plate 11; steel bar holes are reserved in the base plate 11, and a plurality of steel bars in a circle at the upper end of the steel cage are inserted into the steel bar holes together and anchored by pouring grouting material.

[0039] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
