Abstract
Description
Technical Field
[0001] The present application relates to the technical field of engineering construction, and in particular to a large prefabricated retaining wall structure. Background Art
[0002] A retaining wall is a structure that supports the roadbed fill or hillside soil and prevents the fill or soil from deforming and becoming unstable. In the cross section of a retaining wall, the part that is in direct contact with the supported soil is called the wall back; the part facing the air opposite to the wall back is called the wall face; the part that is in direct contact with the foundation is called the base; the top surface of the wall opposite to the base is called the wall top; the front end of the base is called the wall toe; and the rear end of the base is called the wall heel.
[0003] The main function of retaining walls is to withstand lateral earth pressure to stabilize soil or slopes and prevent collapse and landslides. It is widely used in engineering fields such as highways, railways, water conservancy, construction, and mining to support embankment slopes, tunnel openings, bridge ends, and river banks.
[0004] Since the on-site construction of retaining walls requires a long time for solidification, in order to facilitate faster construction of retaining walls, prefabricated retaining walls have been used in the prior art. During construction, the prefabricated retaining wall blocks are spliced together to quickly complete the construction of the retaining wall. At that time, when splicing the retaining walls, the two retaining walls could not be quickly put together, resulting in a problem of low construction efficiency. In order to splice the prefabricated retaining walls faster, the utility model applies for a large prefabricated retaining wall structure. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a large prefabricated retaining wall structure to solve
[0006] The above-mentioned purpose of the present application is achieved through the following technical scheme: a large prefabricated retaining wall structure, including a prefabricated wall, the prefabricated wall includes a vertical wall and a horizontal wall, the vertical wall and the horizontal wall are vertically connected and fixedly connected together, a flange is fixedly provided on one side of the vertical wall, a groove is provided at the other end of the vertical wall, and hanging rings are fixedly provided on the vertical wall and the horizontal wall.
[0007] By adopting the above technical solution, before the installation construction, the foundation for placing the prefabricated wall is excavated, and the entire prefabricated wall is lifted up by using a 50T crane to hook the lifting ring and place it in the foundation. After the first prefabricated wall is placed, the vertical front upper flange of the second prefabricated wall is aligned with the groove opened on the first prefabricated wall, and then the crane is used to place it. When the second prefabricated wall is placed on the ground, the alignment and splicing are directly completed, thereby improving the efficiency of the construction and splicing of prefabricated walls.
[0008] Furthermore, two of the hanging rings are arranged on the vertical wall and the horizontal wall, respectively. The hanging rings on the vertical wall are inclined upward and the angle between the hanging rings and the horizontal line is between 55 degrees and 60 degrees.
[0009] By adopting the above technical solution, the inclined lifting ring design can make the force during the lifting process more uniform, reduce the stress concentration caused by lifting, and thus avoid damage or deformation of the retaining wall during the lifting process. At the same time, the setting of the tilt angle also helps to control the posture of the retaining wall in the air, so that it can be placed in the predetermined position more accurately.
[0010] Furthermore, the cross section of the flange is wide at the top and narrow at the bottom, both sides of the flange are inclined, and the cross section of the groove matches the flange.
[0011] By adopting the above technical solution, considering that the material of the prefabricated wall is concrete, the flange and the groove are very rough. In order to reduce the friction between the flange and the groove during splicing, through the above-mentioned setting, when the flange is installed in the groove, the narrow end below the flange is installed into the middle end of the groove. During the installation process, since both sides of the flange and the groove are inclined, the friction will be reduced.
[0012] Furthermore, a reinforcing layer is provided on the prefabricated wall, and the reinforcing layer is evenly arranged on the prefabricated wall. A fixing plate is provided on the reinforcing layer near the edge of the prefabricated wall, and a through hole is provided on the fixing plate. The reinforcing layer is provided with fixing holes for bolt fixing.
[0013] By adopting the above technical solution, the setting of the reinforcement layer can improve the strength of the retaining wall after the construction of the prefabricated wall is completed. After the splicing of the prefabricated wall is completed, the retaining wall is fixed by bolts that pass through the through holes of the fixing plate or that one and then enter the fixing holes on the reinforcement layer.
[0014] Furthermore, a drainage hole is opened on the vertical wall, and a drainage pipe is fixedly arranged in the drainage hole.
[0015] By adopting the above technical solution, the setting of drainage holes helps to reduce the water pressure on the retaining wall. In particular, setting drainage holes at the bottom of the retaining wall can significantly reduce the water pressure, thereby avoiding soil compression and reducing the risk of wall sinking or collapse.
[0016] Furthermore, a sand and gravel filter is fixedly arranged on the drain pipe.
[0017] By adopting the above technical solution, in order to prevent sand and gravel from leaking out of the drain hole, the sand and gravel filter will block the sand and gravel from leaking out of the drain hole from the other end.
[0018] Furthermore, the cross section of the horizontal wall is inclined, and an end close to the vertical wall is higher than an end away from the vertical wall.
[0019] By adopting the above technical solution, when the water flows out of the drainage holes on the other side of the retaining wall and flows onto the horizontal wall, it will continue to flow directly to the foundation at one end of the ground wall away from the vertical wall, thereby preventing the flowing water from staying on the horizontal wall.
[0020] Furthermore, a plurality of drainage pipes are evenly arranged on the prefabricated wall.
[0021] By adopting the above technical solution, the water at the other end of the retaining wall can be effectively dredged.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. After the foundation for placing the prefabricated wall is excavated, a 50T crane is used to hook the lifting ring, lift the entire prefabricated wall, and place it in the foundation. After placing the first prefabricated wall, align the vertical front upper flange of the second prefabricated wall with the groove opened on the first prefabricated wall, and then place it with the crane. When the second prefabricated wall is placed on the ground, the alignment and splicing are directly completed, thereby improving the efficiency of the construction and splicing of prefabricated walls.
[0024] 2. The inclined lifting ring design can make the force during the lifting process more uniform, reduce the stress concentration caused by lifting, and thus avoid damage or deformation of the retaining wall during the lifting process. At the same time, the setting of the tilt angle also helps to control the posture of the retaining wall in the air, so that it can be placed in the predetermined position more accurately.
[0025] 3. When installing the flange into the groove, install the narrow end of the flange below into the end in the groove. During the installation process, the flange and the groove have inclined surfaces on both sides, which will reduce friction. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present application is further described in detail below with reference to the accompanying drawings.
[0030] Example, see Figure 1 , Figure 2 A large prefabricated retaining wall structure comprises a prefabricated wall 1, wherein the prefabricated wall 1 comprises a vertical wall 102 and a horizontal wall 101, wherein the vertical wall 102 and the horizontal wall 101 are vertically connected and fixedly connected together, a flange 302 is fixedly arranged on one side of the vertical wall 102, a groove 303 is opened at the other end of the vertical wall 102, and a lifting ring 201 is fixedly arranged on the vertical wall 102 and the horizontal wall 101. Before installation and construction, the foundation for placing the prefabricated wall 1 is excavated, and the lifting ring 201 is hooked by using a 50T crane to lift the whole prefabricated wall 1 and place it in the foundation. After placing the first prefabricated wall 1, the vertical front upper flange 302 of the second prefabricated wall 1 is aligned with the groove 303 opened on the first prefabricated wall 1, and then the crane is used to place it. When the second prefabricated wall 1 is placed on the ground, the alignment and splicing are directly completed, thereby improving the efficiency of the construction and splicing of the prefabricated wall 1.
[0031] In this embodiment, two lifting rings 201 are provided on each of the vertical wall 102 and the horizontal wall 101. The lifting rings 201 on the vertical wall 102 are tilted upward and the angle between them and the horizontal line is 55 degrees. The tilted lifting rings 201 design can make the force during the lifting process more uniform, reduce the stress concentration phenomenon caused by the lifting, and thus avoid the retaining wall from being damaged or deformed during the lifting process. At the same time, the setting of the tilt angle also helps to control the posture of the retaining wall in the air, so that it can be placed in the predetermined position more accurately.
[0032] In this embodiment, the cross-section of the flange 302 is wide at the top and narrow at the bottom, and the two sides of the flange 302 are inclined. The cross-section of the groove 303 matches the flange 302. Considering that the material of the prefabricated wall 1 is concrete, the flange 302 and the groove 303 are very rough. In order to reduce the friction between the flange 302 and the groove 303 during splicing, through the above-mentioned arrangement, when the flange 302 is installed in the groove 303, the narrow end at the bottom of the flange 302 is installed into the end in the groove 303. During the installation process, since the two sides of the flange 302 and the groove 303 are inclined, the friction will be reduced.
[0033] In this embodiment, a reinforcing layer 2 is provided on the prefabricated wall 1, and the reinforcing layer 2 is evenly arranged on the prefabricated wall 1. A fixing plate 202 is provided on the reinforcing layer 2 near the edge of the prefabricated wall 1, and a through hole 203 is provided on the fixing plate 202. A fixing hole 204 for bolt fixing is provided on the reinforcing layer 2. The arrangement of the reinforcing layer 2 can improve the strength of the retaining wall after the construction of the prefabricated wall 1 is completed. After the splicing of the prefabricated wall 1 is completed, the retaining wall is fixed by passing through the through hole 203 of the fixing plate 202 or that one, and then entering the fixing hole 204 on the reinforcing layer 2.
[0034] In this embodiment, a drainage hole is provided on the vertical wall 102, and a drainage pipe 3 is fixedly arranged in the drainage hole. The setting of the drainage hole helps to reduce the water pressure on the retaining wall. In particular, the drainage hole is arranged at the bottom of the retaining wall, which can significantly reduce the water pressure, thereby avoiding soil compression and reducing the risk of wall sinking or collapse. A sand and gravel filter 301 is fixedly arranged on the drainage pipe 3. In order to prevent sand and gravel from leaking out of the drainage hole, the sand and gravel filter 301 will block the sand and gravel from leaking out of the drainage hole from the other end. The cross section of the horizontal wall 101 is inclined, and the end close to the vertical wall 102 is higher than the end away from the vertical wall 102. When the water on the other side of the retaining wall flows out of the drainage hole, it flows to the horizontal wall 101 and will directly continue to flow to the foundation of the end of the ground wall away from the vertical wall 102, thereby preventing the water from staying in the horizontal wall 101. A plurality of drainage pipes 3 are evenly arranged on the prefabricated wall, which can effectively dredge the water at the other end of the retaining wall.
[0035] Specific implementation process;
[0036] Before installation and construction, the foundation for placing the prefabricated wall 1 is excavated, and a 50T crane is used to hook the lifting ring 201, lift the entire prefabricated wall 1, and place it in the foundation. After placing the first prefabricated wall 1, align the vertical front upper flange 302 of the second prefabricated wall 1 with the groove 303 opened on the first prefabricated wall 1, and then place it with the crane. When the second prefabricated wall 1 is placed on the ground, the alignment and splicing are directly completed, thereby improving the efficiency of the construction and splicing of the prefabricated walls 1.
[0037] The inclined lifting ring 201 design can make the force during the lifting process more uniform, reduce the stress concentration caused by the lifting, and thus avoid damage or deformation of the retaining wall during the lifting process. At the same time, the setting of the tilt angle also helps to control the posture of the retaining wall in the air, so that it can be placed in the predetermined position more accurately.
[0038] When the flange 302 is installed in the groove 303, the narrow end of the flange 302 below is installed into the end in the groove 303. During the installation process, the flange 302 and the groove 303 have inclined surfaces on both sides, which can reduce friction.
