Description

Technical Field

[0001] This application relates to the field of retaining wall facing technology, and in particular to a gravity retaining wall facing structure. Background Technology

[0002] With the acceleration of urbanization and the increasing frequency of land development, especially in mountainous and hilly areas, the incidence of geological disasters has been aggravated. Traditional slope protection measures often use concrete retaining walls or steel mesh reinforcement. While these methods can prevent soil erosion and landslides to some extent, they have significant limitations in terms of aesthetics and environmental protection. In recent years, with the improvement of environmental awareness and technological progress, ecological slope protection technology, which is more natural, harmonious and has higher stability, has gradually received attention and development.

[0003] Currently, the commonly used methods in slope protection include: First, traditional concrete retaining walls, which are simple, quick, and low-cost to construct, but their rigidity makes them unsuitable for complex terrain conditions, and long-term exposure makes them susceptible to damage from natural factors. Second, steel mesh reinforcement, which increases the overall stability of the slope by embedding metal mesh within the soil, but also suffers from poor corrosion resistance and high maintenance costs. Third, vegetation slope protection technology, which utilizes the soil-fixing effect of plant roots to improve soil physical properties, enhancing slope stability while beautifying the environment; however, it has a long growth cycle and poor initial protection effect. Each of these three methods has its advantages and disadvantages, but in practical applications, they often fail to fully meet the comprehensive requirements of safety, economy, and aesthetics.

[0004] The aforementioned traditional methods generally suffer from problems such as simple structure and poor adaptability, and are particularly inadequate when dealing with slope treatment under complex geological conditions. In addition, the extensive use of concrete and metal materials not only consumes resources, but also damages the original ecological environment to a certain extent, which does not meet the requirements of the concept of sustainable development. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a gravity retaining wall facing structure, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0006] To achieve the above objectives, this application adopts the following technical solution: a gravity retaining wall facing structure, comprising a slope and supporting columns, wherein four jet grouting piles are uniformly fixedly installed on the outer edge of the supporting columns, and steel wire ropes are fixedly connected to the inner walls of the four jet grouting piles; an installation plate is installed on the outer side of the slope, and an installation hole is formed through the inner wall of the installation plate, with a fastening bolt threaded into the inner wall of the installation hole; retaining wall panel one and retaining wall panel two are respectively installed on the outer side of the slope, and grooves are formed at the bottom of retaining wall panel one and retaining wall panel two, and connecting holes are formed on the side of retaining wall panel one and retaining wall panel two near the grooves.

[0007] In a preferred embodiment, the supporting column is embedded in the inner cavity of the slope, and the ends of the four steel wire ropes away from the jet grouting pile are fixedly connected to the stones embedded in the inner cavity of the slope.

[0008] By adopting the above technical solution, the supporting columns are vertically embedded into the slope foundation, ensuring the stability of the overall structure and thus enhancing the overall stability of retaining wall panel one and retaining wall panel two, especially showing excellent resistance to natural disasters such as rainstorms and floods.

[0009] In a preferred embodiment, the top of the support column is provided with a threaded hole, and the position of the threaded hole corresponds to the position of the mounting hole. The nut of the fastening bolt abuts against the inner wall of the mounting plate, and the end of the fastening bolt away from the nut is threaded to the inner wall of the threaded hole.

[0010] By adopting the above technical solution, the mounting plate and the supporting column can be stably connected, thereby ensuring that the mounting plate can be stably set on the outside of the slope, which facilitates the positioning and installation of retaining wall panel one and retaining wall panel two.

[0011] In a preferred embodiment, the mounting plate is adapted to the groove shape at the bottom of retaining wall panel one and retaining wall panel two, the connecting hole penetrates through retaining wall panel one and retaining wall panel two to the inner wall of the mounting plate, and the inner wall of the connecting hole is threaded with multiple connecting bolts.

[0012] By adopting the above technical solution, the grooves at the bottom of retaining wall panel one and retaining wall panel two can be snapped onto the outer side of the mounting plate, thereby ensuring a stable connection between retaining wall panel one and retaining wall panel two and the mounting plate. Furthermore, their individual design facilitates on-site assembly.

[0013] In a preferred embodiment, the retaining wall panel one and retaining wall panel two are made of high-performance concrete material with a strength higher than C30, and the surface compressive strength can reach 50MPa. The surfaces of the retaining wall panel one and retaining wall panel two are specially treated to form a stone-like texture.

[0014] By adopting the above technical solutions, the strength of retaining wall panel one and retaining wall panel two can be enhanced, thereby improving their compressive strength, ensuring that they will not be easily damaged when subjected to external impact, and improving their robustness.

[0015] In a preferred embodiment, anchor rods are inserted into the inner walls of both retaining wall panel one and retaining wall panel two on the side away from the groove, and the anchor rods are made of Φ25HRB400 threaded steel.

[0016] By adopting the above technical solution, the anchor rods can penetrate deep into the rock or soil layers, tightly connecting the entire retaining wall panel one and retaining wall panel two to the slope foundation, effectively dispersing external loads, and strengthening the foundation bearing capacity at the bottom of retaining wall panel one and retaining wall panel two, avoiding the risk of the entire retaining wall panel one and retaining wall panel two collapsing due to foundation deformation.

[0017] In a preferred embodiment, a plurality of wire meshes are embedded on the outer side of the slope. The wire meshes are positioned between retaining wall panel one and retaining wall panel two and the slope, and are covered with mortar.

[0018] By adopting the above technical solution, mortar can be injected into the middle of the slope and retaining wall panel one and retaining wall panel two, and then wire mesh can be covered inside. This improves the firmness of the slope and retaining wall panel one and retaining wall panel two after assembly. In addition, the mortar can solidify the surrounding loose soil, thus constructing a solid artificial foundation barrier under the foundation of retaining wall panel one and retaining wall panel two. In this way, even in the event of extreme weather conditions causing the groundwater level to rise, the structure of retaining wall panel one and retaining wall panel two can be protected from damage to the greatest extent.

[0019] The beneficial effects of this application are:

[0020] 1. This gravity retaining wall facing structure securely connects the mounting plate and the supporting column with fastening bolts, then lays and fixes retaining wall panel one and retaining wall panel two in sequence, and finally drills and installs anchor rods. High-pressure grouting is used to make the anchor rods tightly bonded to the surrounding rock, thereby achieving the stability of the entire system. In addition to bearing their own weight, retaining wall panel one and retaining wall panel two must also resist the pressure from the soil above and other external loads. The supporting column, as a load-bearing component, is responsible for transferring the load from the superstructure to the slope, thus improving stability.

[0021] 2. This gravity retaining wall structure connects the key components of the ground structure and deep rock by setting anchor rods. Its function is to strengthen the foundation bearing capacity of retaining wall panel one and retaining wall panel two, avoid the risk of the entire retaining wall collapsing due to foundation deformation, and ensure that retaining wall panel one and retaining wall panel two structures are not damaged even in the event of severe weather or groundwater level rise.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Reference Figure 1-4 A gravity retaining wall facing structure includes a slope 1 and supporting columns 2. Four jet grouting piles 3 are uniformly fixedly installed on the outer edge of the supporting columns 2, and steel wire ropes 4 are fixedly connected to the inner walls of the four jet grouting piles 3. An installation plate 5 is installed on the outer side of the slope 1. An installation hole 6 is opened through the inner wall of the installation plate 5. A fastening bolt 7 is threadedly connected to the inner wall of the installation hole 6. A retaining wall panel 1 8 and a retaining wall panel 2 9 are respectively installed on the outer side of the slope 1. A groove 10 is opened at the bottom of both retaining wall panel 1 8 and retaining wall panel 2 9. A connecting hole 11 is opened on the side of retaining wall panel 1 8 and retaining wall panel 2 9 near the groove 10.

[0029] See Figure 1 and Figure 2 The support column 2 is embedded in the inner cavity of the slope 1. The ends of the four steel wire ropes 4 away from the jet grouting pile 3 are fixedly connected to the stones embedded in the inner cavity of the slope 1, so that the support column 2 is vertically embedded in the foundation of the slope 1, ensuring the stability of the overall structure, thereby enhancing the overall stability of retaining wall panel 1 8 and retaining wall panel 2 9, especially showing excellent resistance when encountering natural disasters such as rainstorms and floods.

[0030] See Figure 2 and Figure 3The top of the support column 2 is provided with a threaded hole, and the position of the threaded hole corresponds to the position of the mounting hole 6. The nut of the fastening bolt 7 abuts against the inner wall of the mounting plate 5, and the end of the fastening bolt 7 away from the nut is threaded to the inner wall of the threaded hole, so that the mounting plate 5 and the support column 2 can be stably connected, thereby ensuring that the mounting plate 5 can be stably set on the outer side of the slope 1, which facilitates the positioning and installation of retaining wall panel 1 8 and retaining wall panel 2 9.

[0031] See Figure 2 - Figure 4 The mounting plate 5 is adapted to the shape of the groove 10 at the bottom of the retaining wall panel 8 and the retaining wall panel 9. The connecting hole 11 penetrates the retaining wall panel 8 and the retaining wall panel 9 to the inner wall of the mounting plate 5. Multiple connecting bolts 12 are threaded onto the inner wall of the connecting hole 11, so that the groove 10 at the bottom of the retaining wall panel 8 and the retaining wall panel 9 can be snapped onto the outer side of the mounting plate 5, thereby making the retaining wall panel 8 and the retaining wall panel 9 firmly connected to the mounting plate 5. Moreover, its individual setting makes it easy to assemble on site.

[0032] See Figure 1 - Figure 4 The retaining wall panels 1 and 2 are made of high-performance concrete with a strength higher than C30, and the surface compressive strength can reach 50MPa. The surface of retaining wall panels 1 and 2 is specially treated to form a stone-like texture, which enhances the strength of retaining wall panels 1 and 2, thereby improving their compressive strength and ensuring that they will not be easily damaged when subjected to external impact, thus improving their sturdiness.

[0033] See Figure 2 Anchor rods 14 are inserted into the inner walls of retaining wall panel 18 and retaining wall panel 29 on the side away from the groove 10. The anchor rods 14 are made of Φ25HRB400 threaded steel, which allows the anchor rods 14 to penetrate deep into the rock or soil layer, tightly connecting the entire retaining wall panel 18 and retaining wall panel 29 to the foundation of the slope 1. This effectively disperses the external load and strengthens the foundation bearing capacity at the bottom of retaining wall panel 18 and retaining wall panel 29, avoiding the risk of the entire retaining wall panel 18 and retaining wall panel 29 collapsing due to foundation deformation.

[0034] See Figure 4Several wire meshes 13 are embedded on the outer side of the slope 1. The wire meshes 13 are set in the middle of the retaining wall panel 1 8 and retaining wall panel 2 9 and the slope 1. The wire meshes 13 are covered with mortar, so that the mortar can be poured into the middle of the slope 1 and retaining wall panel 1 8 and retaining wall panel 2 9, thereby covering the wire meshes 13. This can improve the firmness of the slope 1 and retaining wall panel 1 8 and retaining wall panel 2 9 after assembly. In addition, the mortar can solidify the surrounding loose soil, thus building a solid artificial foundation barrier under the foundation of retaining wall panel 1 8 and retaining wall panel 2 9. In this way, even in the event of extreme weather conditions such as rising groundwater levels, the structure of retaining wall panel 1 8 and retaining wall panel 2 9 can be protected from damage to the maximum extent.

[0035] Working principle: After the foundation treatment and leveling are completed at the construction site, support columns 2 are first driven in at predetermined intervals, and the mounting plate 5 is firmly connected to the support columns 2 by fastening bolts 7. Then, retaining wall panel 1 8 and retaining wall panel 2 9 are laid and fixed in sequence. Finally, anchor rods 14 are drilled and installed. High-pressure grouting is used to make the anchor rods 14 tightly bonded to the surrounding rock, thereby achieving the stability of the entire system. In this process, retaining wall panel 1 8 and retaining wall panel 2 9, in addition to bearing their own weight, must also resist the pressure from the soil above and other external loads. The support columns 2, as load-bearing components, are responsible for transmitting the load from the superstructure to the slope 1, while the anchor rods 14 are key components connecting the ground structure and the deep rock. Their function is to strengthen the foundation bearing capacity of retaining wall panel 1 8 and retaining wall panel 2 9, and avoid the risk of the entire retaining wall collapsing due to foundation deformation.
