Description

Technical Field

[0001] The invention relates to the technical field of retaining wall reinforcement, and in particular to a cantilever retaining wall reinforcement structure. Background Art

[0002] As a common civil engineering structure, retaining wall is widely used in infrastructure construction such as roads, bridges, tunnels, ports, etc. Its main function is to support soil and prevent soil landslide and collapse. Existing retaining wall structures mainly include gravity type, cantilever type, anchor type and other types. Among them, the cantilever retaining wall consists of a base plate and a vertical wall fixed on the base plate. This structure mainly relies on the weight of the fill on the base plate to maintain stability. Its main components include three reinforced concrete structures: vertical wall, toe plate and heel plate. In actual engineering, it is widely used because of its simple structure, convenient construction, and reasonable force.

[0003] However, in practical applications, traditional cantilever retaining walls have defects such as poor integrity between the wall and the soil and an imperfect drainage system. In view of the existing problems, a reinforced retaining wall structure disclosed in Chinese Patent Publication No. CN115262622B is referred to. The invention includes a shell, on the back of which a plug-in rod is fixed in a matrix shape. The shell is threaded with a transverse connecting screw and a longitudinal connecting screw, and a filter plate structure is embedded inside. The transverse connecting screw has the same structure as the longitudinal connecting screw. This structure is used by inserting the plug-in rods on multiple devices. When used, the invention shows that the number of plug-in rods on the shell of this technology is large and the distribution is relatively dense, and the plug-in rod is also installed with multiple ribs. The ribs and the plug-in rods are usually installed on the shell by welding, which results in a long time for the early assembly of the retaining wall structure, which affects the subsequent construction efficiency.

[0004] Taking into account the defects of existing cantilever retaining walls and combining the advantages and disadvantages of existing inventions, a new cantilever retaining wall reinforcement structure is proposed, aiming to improve the integrity of the wall and soil, reduce construction difficulty, and enhance the drainage system, thereby improving the stability and service life of the retaining wall.

DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0020] See also Figure 1-7 The embodiment of the present invention discloses a cantilever retaining wall reinforcement structure. Figure 1 and Figure 2 As shown, a reinforcement structure of a cantilever retaining wall includes a vertical wall plate 1, and a plurality of reinforced tubes 2 are installed on the back of the vertical wall plate 1. In this embodiment, there are four reinforced tubes 2 and they are arranged at the four corners of the back of the vertical wall plate 1. One end of the reinforced tube 2 away from the vertical wall plate 1 is a pointed cone-shaped earth-breaking end 21. During the construction process, the worker will insert the reinforced tube 2 into the soil through the earth-breaking end 21, so that the back of the vertical wall plate 1 is close to the soil to achieve the earth-retaining function.

[0021] like Figure 2 , Figure 3 and Figure 6 As shown, a plurality of connecting holes 22 are provided on the upper portion of the reinforced tube 2, and a plurality of fixed tubes 23 are installed inside the reinforced tube 2. The fixed tubes 23 correspond to the connecting holes 22 one by one, one end of the fixed tube 23 is connected to the connecting hole 22, and the other end of the fixed tube 23 is sealed by the inner wall of the reinforced tube 2, so that the interior of the fixed tube 23 is not connected to the interior of the reinforced tube 2.

[0022] The same water guide column 3 is slidably penetrated in the corresponding fixed pipes 23 and the connecting holes 22, and all the fixed pipes 23 are connected to the same connecting pipe 4, one end of the connecting pipe 4 is penetrated through the vertical wall plate 1 and extends to the front of the vertical wall plate 1, and this end of the connecting pipe 4 is connected to an external liquid pump.

[0023] When the back side of the vertical wall panel 1 is in close contact with the soil, the external liquid pump will fill the connecting pipe 4 with liquid, and the liquid in the connecting pipe 4 will push the water guiding column 3 to gradually extend out of the reinforced pipe 2, that is, the water guiding column 3 will slide along its own axial direction and be inserted into the soil; in this embodiment, the reinforced pipe 2 is inserted into the soil horizontally, and the water guiding column 3 is inserted into the soil vertically, and the water guiding column 3 and the reinforced pipe 2 jointly limit the vertical wall panel 1, thereby increasing the stability of the connection between the retaining wall and the soil.

[0024] like Figure 2 and Figure 4 As shown, one end of the connecting tube 4 extending to the front side of the vertical wall panel 1 is connected to a buckle cover 42 through a connecting rope 41. The buckle cover 42 is used to buckle and seal the port of the connecting tube 4 so that the port of the connecting tube 4 is not easily exposed to prevent mosquitoes or debris from entering the connecting tube 4.

[0025] like Figure 2 and Figure 3 As shown, the interior of the vertical wall plate 1 is hollow and connected to the reinforced pipe 2, the interior of the water guide column 3 is hollow and connected to the interior of the reinforced pipe 2, and a plurality of first water permeable holes 31 are provided on the water guide column 3, so that the water in the soil can enter the interior of the vertical wall plate 1 through the first water permeable holes 31, the interior of the water guide column 3 and the interior of the reinforced pipe 2 in sequence, so that the water in the soil can be discharged, thereby ensuring the stability of the connection between the retaining wall and the soil.

[0026] It is worth noting that each water guide column 3 can guide the water in the soil within a certain area, and the two adjacent water guide columns 3 complement each other in the area, so as to more comprehensively cover the inside of the soil to ensure the guiding effect of the water in the soil; in addition, the first water permeable holes 31 are distributed on the top and sides of the water guide columns 3, so that the water entering the water guide columns 3 is not easy to seep downward; the connecting holes 22 are distributed on the top and left and right sides of the reinforced pipe 2, so that the water entering the reinforced pipe 2 is not easy to seep downward, so as to ensure that the water in the soil can enter the interior of the vertical wall panel 1 as much as possible.

[0027] like Figure 1 As shown, drainage holes 11 are provided at the top and bottom of the vertical wall panels 1. When a plurality of vertical wall panels 1 are sequentially installed on the soil in a matrix shape, the water inside the vertical wall panels 1 on the upper side can flow downward to the inside of the vertical wall panels 1 on the lower side; and the inside of the vertical wall panels 1 on the lower side is connected to the external drainage equipment, so that the water inside the vertical wall panels 1 can be discharged in time.

[0028] It is worth noting that the present invention only needs to weld four reinforced tubes 2 on the vertical wall plate 1, and by controlling the external liquid pump, the water in the soil can be discharged. There is no need to weld multiple reinforcement rods and plug-in rods on the shell as in the prior art. Therefore, the present invention improves the construction efficiency of the retaining wall.

[0029] When the liquid pump draws liquid into the connecting pipe 4, the liquid in the fixed pipe 23 will flow back to the liquid pump through the connecting pipe 4, and the water guide column 3 will move toward the inside of the fixed pipe 23, so that the extension length of the water guide column 3 from the inside of the reinforced pipe 2 becomes smaller, so that the vertical wall panel 1 can be removed from the soil.

[0030] like Figure 2As shown, a plurality of rib plates 5 are installed on the upper part of the reinforced tube 2, and there are three rib plates 5, which are respectively distributed on the top and left and right sides of the reinforced tube 2, and the side of the rib plate 5 away from the vertical wall plate 1 is a blade-shaped ground-breaking surface 51. When the reinforced tube 2 is inserted into the soil, the rib plate 5 will be inserted into the soil through the ground-breaking surface 51, thereby improving the stability of the connection between the retaining wall and the soil.

[0031] like Figure 2 and Figure 3 As shown, the rib plate 5 is provided with a connecting channel 52 and a plurality of penetration holes 53, the penetration holes 53 correspond to the connecting holes 22 one by one and are connected to each other, and the water guide column 3 is slidably penetrated through the penetration holes 53. When the liquid pump fills the connecting pipe 4 with liquid, the liquid in the fixed pipe 23 will push the water guide column 3 to move, one end of the water guide column 3 will extend to the outside of the reinforced pipe 2 and the rib plate 5, and the other end of the water guide column 3 will move into the penetration hole 53, at this time, the inside of the water guide column 3 will be connected to the inside of the reinforced pipe 2 through the connecting channel 52, the water in the soil can enter the water guide column 3 through the first water permeable hole 31 on one end of the water guide column 3 extending to the outside of the reinforced pipe 2 and the rib plate 5, the water in the water guide column 3 can enter the reinforced pipe 2 through the connecting channel 52, and the water in the reinforced pipe 2 can enter the vertical wall plate 1, so as to be discharged through the external drainage equipment.

[0032] like Figure 3 , Figure 4 and Figure 7 As shown, the upper part and the side part of the rib plate 5 are provided with a plurality of second water-permeable holes 54 connected to the connecting channel 52, so that the water in the soil can directly enter the connecting channel 52 through the second water-permeable holes 54, so as to discharge the water in the soil.

[0033] like Figure 7 As shown, a plurality of ear plates 55 are installed on the rib plate 5, and the ear plates 55 are fixed on the reinforced tube 2 by bolts 56, so as to facilitate the assembly and disassembly of the rib plate 5 on the reinforced tube 2; there are at least two rib plates 5 between every two adjacent reinforced tubes 2 to ensure the liquid conducting effect on the water in the soil.

[0034] like Figure 3 and Figure 4 As shown, a positioning ring 24 and a pull rope 25 are provided in the fixed tube 23, the positioning ring 24 is fixedly embedded in the fixed tube 23, and the pull rope 25 is connected to the water guide column 3 and the inner wall of the reinforced tube 2. When the inside of the water guide column 3 is connected to the inside of the reinforced tube 2 through the connecting channel 52, the pull rope 25 will be in a straightened state and prevent the water guide column 3 from continuing to extend outside the rib plate 5, thereby ensuring the smooth discharge of water in the soil.

[0035] When the water guide column 3 moves toward the fixing pipe 23 , the positioning ring 24 will abut against the water guide column 3 and prevent the water guide column 3 from further penetrating into the reinforced pipe 2 . At this time, the water guide column 3 has been separated from the soil, so that the vertical wall panel 1 can be removed from the soil.

[0036] The working principle of the present invention is as follows: during the construction process, workers will insert the reinforced tube 2 into the soil through the ground-breaking end 21, and the rib plate 5 will be inserted into the soil through the ground-breaking surface 51, and the back of the vertical wall panel 1 will be close to the soil; then the external liquid pump will fill the connecting tube 4 with liquid, and the liquid in the connecting tube 4 will push the water guide column 3 to be inserted into the soil. At this time, the water guide column 3, the rib plate 5 and the reinforced tube 2 have been inserted into the soil together, realizing multi-directional fixation of the vertical wall panel 1 and enhancing the stability of the connection between the vertical wall panel 1 and the soil.

[0037] The water in the soil can enter the vertical wall plate 1 through the first water permeable hole 31, the inside of the water guide column 3, the connecting channel 52 and the inside of the reinforced tube 2 in sequence, and can also enter the vertical wall plate 1 through the second water permeable hole 54, the connecting channel 52 and the inside of the reinforced tube 2 in sequence. The water in the vertical wall plate 1 can gradually flow downward through the drainage hole 11 and be discharged through the external drainage equipment.

[0038] In summary, the present invention can fix the vertical wall plate 1 on the soil in multiple directions by controlling the external liquid pump, and every two adjacent water guide columns 3 in the present invention can be regionally complementary, so as to more comprehensively cover the inside of the soil, realize the comprehensive drainage of the water in the soil, and increase the stability of the connection between the vertical wall plate 1 and the soil; in addition, the present invention only needs to weld four reinforced tubes 2 on the vertical wall plate 1, and there is no need to weld multiple reinforcement rods and plug-in rods on the shell as in the prior art, so the present invention improves the construction efficiency of the retaining wall. Example 2

[0039] According to the requirements of the Railway Roadbed Support Structure Design Code, the longitudinal reinforcement of cantilever retaining walls should generally be HRB400 grade steel bars. Example 3

[0040] The difference between this embodiment and embodiment 2 is that part of the steel bars inside the cantilever retaining wall are replaced with Shape memory alloy (SMA), as a new functional material, has the characteristics of shape memory effect, superelasticity, elastic modulus changes with temperature, limited recovery can output large driving force and high damping, etc. SMA tendons in the martensitic state at room temperature are pre-stretched and embedded in concrete beams to make shape memory alloy concrete beams. By utilizing the shape memory effect of shape memory alloy and the characteristics of large driving force output during limited recovery, the deformation and deflection of the structure can be effectively controlled and repaired, thereby realizing the self-repair of concrete cracks.
