Technical Field

[0001] This utility model relates to the field of engineering geological retaining wall technology, specifically a retaining wall that can be used in engineering geology. Background Technology

[0002] In various engineering construction projects, especially in the fields of roads, railways, water conservancy and hydropower, and mining, complex engineering geological conditions are often encountered during construction, such as high mountains and canyons, steep slopes, loose deposits, and weak coal seam roadways. When carrying out engineering construction in these areas, in order to prevent landslides, falling rocks, water erosion and other hazards from damaging the construction route and to ensure the safe operation of the project, it is usually necessary to set up a large number of retaining walls for protection and support.

[0003] Traditional retaining walls mostly adopt a vertical support structure. As a supporting structure for soil blocking, the vertical wall requires multiple sets of supporting and reinforcing structures on the outside of the wall to ensure its structural stability. This not only makes the construction operation complicated but also occupies a large amount of space outside the wall. Therefore, a retaining wall that can be used for engineering geology is proposed. Utility Model Content

The retaining wall body is T-shaped, and a beam frame mounting groove is provided at the front of the retaining wall body. The reinforcing beam frame is L-shaped and is fastened to the inner side of the beam frame mounting groove by fitting the groove with bolts. An anchor bolt mounting holes are provided at the upper part of the base of the front of the retaining wall body, and a rear reinforcing rib is provided at the rear of the retaining wall body. The retaining wall body is provided with positioning head posts and positioning protrusions on its side, and adjacent retaining wall bodies are positioned and spliced ​​together by the cooperation of positioning head posts and positioning protrusions.

The positioning protrusion 6 is fixedly installed on the inner side of the positioning groove 4 by limiting the positioning bolt. Adjacent retaining wall bodies 1 are fitted and positioned by positioning head post 5 in conjunction with the positioning protrusion 6. The structure is simple and the installation is convenient, which greatly improves the installation convenience of the retaining wall body 1.

[0022] As attached Figure 3 As shown, the reinforcing beam 2 is an L-shaped steel beam frame. To facilitate the connection and installation of the reinforcing beam 2, a beam frame mounting groove 8 is provided at the front of the retaining wall body 1. The reinforcing beam 2 is fastened to the inner side of the beam frame mounting groove 8 by fitting the groove with bolts. Specifically, there are multiple beam frame mounting grooves 8, which are evenly spaced at the front of the retaining wall body 1. The beam frame mounting grooves 8 are adapted to the reinforcing beam 2, and the reinforcing beam 2 is fitted into the inner side of the beam frame mounting groove 8. Fastening screw holes are provided on the edge of the reinforcing beam 2. After installation, the reinforcing beam 2 is fixedly installed to the retaining wall body 1 by bolts. To improve the support stability of the retaining wall body 1, as shown in the attached figure... Figure 4As shown, a rear reinforcing rib 10 is provided at the rear of the retaining wall body 1. Multiple rear reinforcing ribs 10 are provided and are fixedly installed at equal intervals at the rear of the retaining wall body 1. The rear reinforcing ribs 10 are located on the opposite side of the beam frame mounting groove 8. The retaining wall reinforcement structure adopts a split beam frame type. The reinforcing beam frame 2 is connected and installed by fitting the beam frame mounting groove 8 with bolts, so that the reinforcing beam frame 2 and the retaining wall body 1 form an integrated retaining wall support structure. The rear reinforcing ribs 10 provided at the rear of the retaining wall body 1 can effectively improve the structural support strength of the retaining wall body 1, and have better compressive support capacity compared with traditional pure concrete walls.

[0023] To facilitate connection and installation with the anchor bolt's guy wire section, see attached... Figure 3 As shown, anchor bolt mounting holes 9 are provided on the upper part of the base of the retaining wall body 1. Multiple anchor bolt mounting holes 9 are provided, and these holes 9 are evenly spaced and uniformly opened through the upper part of the base of the retaining wall body 1, as shown in the attached diagram. Figure 5 As shown, after installation, the base of the retaining wall body 1 is pulled and limited by anchor bolts. The limiting and reinforcement of the anchor bolts can further improve the structural support stability of the retaining wall body 1, which is conducive to improving the working stability of the retaining wall.

[0024] Working principle or structural principle: During installation, the reinforcing beam 2 is first fitted into the beam mounting groove 8 on the upper part of the retaining wall body 1. Then, the installed reinforcing beam 2 is locked and limited by bolts. The anchor bolt line is passed through the anchor bolt mounting hole 9 on the upper part of the retaining wall body 1. Then, the retaining wall body 1 is pushed to the slope support installation location. Then, the positioning head column 5 and positioning protrusion 6 are aligned and fitted with the groove on the side of the retaining wall body 1 to complete the positioning and splicing between adjacent retaining wall bodies 1. Then, the positioning protrusion 6 and positioning head column 5 are locked and limited by the limiting bolt column and limiting pin column respectively. After completion, the anchor bolt line is tensioned and fixed to complete the installation of the retaining wall. During operation, the soil support is compacted on the base plane of the retaining wall body 1. Under the pressure of the soil, it can stably support the ground support. The greater the installation pressure, the more stable the support. With the anchor bolts and wires, the tension support of the base of the retaining wall body 1 can ensure the stable support between the retaining wall body 1 and the ground. When the retaining wall body 1 is subjected to lateral pressure, the reinforcement beam 2 connected to the retaining wall body 1 can effectively improve the structural support strength of the retaining wall body 1, and prevent the vertical wall part of the retaining wall body 1 from cracking and breaking due to excessive stress. Compared with traditional pure concrete walls, it has better compressive support capacity.

[0025] In summary, this retaining wall adopts a prefabricated splicing wall installation structure. The prefabricated retaining wall body 1 serves as the soil support structure. The retaining wall body 1 is T-shaped, allowing for stable soil support through the soil's own weight. This eliminates the need for complex support and reinforcement structures at the rear of the retaining wall, improving construction convenience and space utilization. Furthermore, adjacent retaining wall bodies 1 are positioned and assembled using positioning head columns 5 and positioning protrusions 6, resulting in a simple structure and convenient installation, significantly enhancing the ease of installation of the retaining wall body 1. The use of a split beam frame retaining wall reinforcement structure further enhances this advantage. The reinforced beam frame 2 is connected and installed by fitting the beam frame mounting groove 8 with bolts, so that the reinforced beam frame 2 and the retaining wall body 1 form an integrated retaining wall support structure. The rear reinforcing rib 10 set at the rear of the retaining wall body 1 can effectively improve the structural support strength of the retaining wall body 1. Compared with the traditional pure concrete wall, it has better compressive support capacity. Furthermore, the flat bottom support side of the retaining wall body 1 is provided with anchor bolt mounting holes 9. With the limit reinforcement of the anchor bolts, the structural support stability of the retaining wall body 1 can be further improved, which is conducive to improving the working stability of the retaining wall.
