Description

Technical Field

[0001] This utility model relates to the field of retaining wall structure technology, specifically a retaining wall structure for improving the stability of roadbed slopes. Background Technology

[0002] The location of roadbed slopes is affected by external forces such as vehicle loads and natural environment, which can lead to landslides, slope collapses, and subsidence of varying degrees. This is because the internal structure of the roadbed is damaged by rain, snow, and heavy vehicles, resulting in a decrease in the strength of the roadbed and the overall stability of the structure. This causes uneven structural forces, which can easily lead to problems such as internal voids, landslides, and slope collapses, thereby affecting the driving safety of vehicles.

[0003] In existing technologies, retaining wall structures are generally laid on both sides of the road. The retaining wall structure mainly includes a retaining wall anti-corrosion protective layer, a retaining wall body, a high-toughness reinforced grid, an asphalt waterproof layer, a drainage crushed stone layer, and a durable reinforced concrete connecting layer. The retaining wall body has an inverted "T" shape. After the retaining wall structure is laid, the roadbed is laid on one side of the retaining wall body. After the roadbed is compacted, asphalt material is laid on top to complete the road paving. The pressure on the road is transmitted to the retaining wall body, which generates a large friction between the bottom of the retaining wall body and the ground, making it difficult for the retaining wall body to shift. The retaining wall provides lateral support to the roadbed slope, thereby improving the stability of the roadbed slope.

[0004] However, in existing retaining walls, the steel reinforcement is usually erected and the concrete is poured and dried on-site during road paving, followed by the construction of subsequent structures such as waterproofing layers. This makes the entire construction process of retaining walls very time-consuming. When paving urban roads, the excessively long construction period will place a heavy burden on urban traffic, so this problem urgently needs to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a retaining wall structure that improves the stability of roadbed slopes, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a retaining wall structure for improving the stability of roadbed slopes, comprising: a retaining wall base and a retaining wall body, wherein a positioning groove is provided on the retaining wall base, a positioning rod is fixed at the bottom end of the retaining wall body, the positioning rod is movably inserted into the positioning groove, a grout channel is provided on the retaining wall body, and a grouting hole is provided on the positioning rod.

[0007] Preferably, the positioning grooves and positioning rods are provided in several groups, and the several groups of positioning grooves and several groups of positioning rods are distributed in a linear array.

[0008] Preferably, a filling layer is formed between the bottom end of the retaining wall and the base of the retaining wall.

[0009] Preferably, a stopper is movably inserted at the top of the slurry channel, and a rubber pad is fixed on the stopper. The rubber pad has an annular cylindrical structure, and a handle is fixed at the top of the rubber pad.

[0010] Preferably, a high-toughness reinforced grid for retaining walls is fixed on one side of the retaining wall.

[0011] Preferably, both the retaining wall base and the retaining wall body are covered with an asphalt waterproof layer and an anti-corrosion protective layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model proposes a retaining wall structure to improve the stability of roadbed slopes. Both the retaining wall base and the retaining wall body are prefabricated separately in a factory and transported to the road construction site. Upon arrival, positioning rods fixed to the bottom of the retaining wall body are inserted into positioning grooves opened on the retaining wall base. After the retaining wall base and retaining wall body are assembled, a filling layer is formed. Concrete is poured in from the top opening of the grout channel. After both the filling layer and the grout channel are filled, the alignment of the positioning groove and positioning rod ensures that the assembly between the retaining wall body and the retaining wall base already possesses a certain degree of stability. Therefore, subsequent construction work can proceed immediately without waiting for the concrete in the filling layer to dry, greatly shortening the construction period of the retaining wall structure. Furthermore, once the concrete in the filling layer has dried, the retaining wall base and retaining wall body are fused together as a whole, ensuring that the retaining wall structure has the required stability.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a retaining wall structure for improving the stability of roadbed slopes, comprising: a retaining wall base 1 and a retaining wall body 2. The retaining wall base 1 is provided with a positioning groove 3. The bottom end of the retaining wall body 2 is fixed with a positioning rod 4, which is movably inserted into the positioning groove 3. The retaining wall body 2 is provided with a grout channel 7, and the positioning rod 4 is provided with a grouting hole 6. Several sets of positioning grooves 3 and positioning rods 4 are provided, and the several sets of positioning grooves 3 and several sets of positioning rods 4 are arranged in a linear array. A filling layer 5 is formed between the bottom end of the retaining wall body 2 and the retaining wall base 1.

[0023] In actual use, both the retaining wall base 1 and the retaining wall body 2 are prefabricated separately in the factory. The reinforced concrete structure used to construct the retaining wall base 1 and retaining wall body 2 is cured to the required state and then transported to the road construction site. Upon arrival, the positioning rod 4 fixed to the bottom of the retaining wall body 2 is inserted into the positioning groove 3 opened on the retaining wall base 1. After the retaining wall base 1 and retaining wall body 2 are assembled, a filling layer 5 is formed. A baffle is fixed to the bottom of the retaining wall body 2 to seal the openings at both ends of the filling layer 5. Therefore, both ends of the filling layer 5 are in a sealed state, allowing concrete to flow from... The grout is poured into the top opening of the grout channel 7. The concrete is poured into the filling layer 5 through the grout channel 7 and the grouting hole 6. After the filling layer 5 and the grout channel 7 are filled, the assembly between the retaining wall body 2 and the retaining wall base 1 has a certain degree of stability due to the cooperation of the positioning groove 3 and the positioning rod 4. Therefore, there is no need to wait for the concrete in the filling layer 5 to dry before the subsequent work can be carried out immediately, which greatly shortens the construction period of the retaining wall structure. At the same time, when the concrete in the filling layer 5 dries, the retaining wall base 1 and the retaining wall body 2 are fused into a whole, which can ensure that the retaining wall structure has the required stability.

[0024] Example 2: Based on Example 1, in order to prevent foreign objects from entering the slurry channel 7 during transportation and causing blockage of the slurry channel 7, a stopper 8 is movably inserted into the top of the slurry channel 7. A rubber pad 9 is fixed on the stopper 8. The rubber pad 9 has a ring-shaped cylindrical structure, and a handle 10 is fixed to the top of the rubber pad 9.

[0025] During transportation, the stopper 8 is inserted into the top opening of the slurry channel 7 to seal the opening and prevent foreign objects from entering the slurry channel 7 and causing blockage. The rubber pad 9 fixed on the stopper 8 has a large roughness to prevent the stopper 8 from sliding out of the slurry channel 7 on its own. When it is necessary to pour concrete into the slurry channel 7, the stopper 8 can be pulled out of the slurry channel 7 by pinching the handle 10.

[0026] Example 3: Based on Example 2, in order to further increase the service life of the retaining wall structure, a high-toughness reinforced grid 12 is fixed on one side of the retaining wall body 2, and an asphalt waterproof layer 11 and an anti-corrosion protective layer 13 are applied to both the retaining wall base 1 and the retaining wall body 2.

[0027] An asphalt waterproof layer 11 is laid along the edge of the retaining wall and onto the retaining wall body 2. The reinforcing bars are aligned with the direction of traffic and are fixed with explosive studs to a depth of 3-5 cm. The explosive studs are evenly distributed at a density of approximately 10-15 per square meter. Subsequently, the asphalt waterproof layer 11 and the anti-corrosion protective layer 13 are sequentially laid on the retaining wall base 1 and the retaining wall body 2. This effectively prevents the retaining wall base 1 and the retaining wall body 2 from detaching due to immersion and corrosion caused by rain and snow, thereby improving the overall stability of the retaining wall and extending its service life.

[0028] In actual use, both the retaining wall base 1 and the retaining wall body 2 are prefabricated separately in the factory. The reinforced concrete structure used to construct the retaining wall base 1 and retaining wall body 2 is cured to the required state and then transported to the road construction site. Upon arrival, the positioning rod 4 fixed to the bottom of the retaining wall body 2 is inserted into the positioning groove 3 opened on the retaining wall base 1. After the retaining wall base 1 and retaining wall body 2 are assembled, a filling layer 5 is formed. A baffle is fixed to the bottom of the retaining wall body 2 to seal the openings at both ends of the filling layer 5. Both ends of the filling layer 5 are sealed. Concrete is poured into the filling layer 5 through the top opening of the grout channel 7. After the filling layer 5 and the grout channel 7 are filled, the assembly between the retaining wall body 2 and the retaining wall base 1 has a certain degree of stability due to the cooperation of the positioning groove 3 and the positioning rod 4. Therefore, subsequent work can be carried out immediately without waiting for the concrete in the filling layer 5 to dry, which greatly shortens the construction period of the retaining wall structure. At the same time, after the concrete in the filling layer 5 dries, the retaining wall base 1... The retaining wall 2 is integrated with the retaining wall body 2 to ensure the retaining wall structure has the required stability. During transportation, the plug 8 is inserted into the top opening of the grout channel 7 to seal the opening and prevent debris from entering and clogging the grout channel 7. The rubber pad 9 fixed on the plug 8 has a large roughness to prevent the plug 8 from sliding out of the grout channel 7. When it is necessary to pour concrete into the grout channel 7, the plug 8 can be pulled out of the grout channel 7 by squeezing the handle 10. Along the edge of the retaining wall The retaining wall body 2 is covered with an asphalt waterproof layer 11, with the reinforcing bars aligned with the direction of traffic and secured with explosive studs to a depth of 3-5 cm. The explosive studs are evenly distributed at approximately 10-15 per square meter. Subsequently, the asphalt waterproof layer 11 and the anti-corrosion protective layer 13 are sequentially applied to the retaining wall base 1 and the retaining wall body 2. This effectively prevents the retaining wall base 1 and the retaining wall body 2 from detaching due to immersion and corrosion caused by rain and snow, thereby improving the overall stability of the retaining wall and extending its service life.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
