Description

Technical Field

[0001] The present application relates to the technical field of building construction, and particularly relates to a gravity retaining wall. Background Art

[0002] A gravity retaining wall maintains its stability under the action of earth pressure by its own gravity. It is a commonly used retaining wall in China. The gravity retaining wall can be built with stone or concrete, and is generally made into a simple trapezoid.

[0003] Currently, during the construction of the existing gravity retaining wall, it is necessary to first dig a foundation pit, then erect a formwork to pour the base. After the base curing is completed, erect the formwork again to pour the wall body, and then cure the concrete. After the concrete reaches the specified strength, remove the formwork. Finally, backfill and tamp the back of the wall. In addition, the outer layer of the existing wall ring is made of plastic, which is exposed to the sun and rain in the open air, easily ages, the color changes, affecting the appearance, and has a short service life. And the wall ring made of bricks, especially the temporary wall ring on the construction site, is inconvenient to disassemble, cannot be reused, and will also generate a large amount of construction waste, affecting the environment and causing waste of resources.

[0004] Regarding the above related technologies, the inventor believes that the construction of the retaining wall requires processes such as erecting formwork, pouring and curing, and removing formwork, with a long construction period and difficult to control the construction quality. Especially for the temporary retaining wall on the construction site, it is inconvenient to disassemble, cannot be reused, and will also generate a large amount of construction waste, affecting the environment and causing waste of resources. Summary of the Invention

[0005] In order to save resources and facilitate recycling, the present application provides a gravity retaining wall.

[0007] A gravity retaining wall includes a base. One end of the base is fixedly connected with a mounting plate, and the other end of the base is provided with a fixing groove for slidingly cooperating with the mounting plate. A positioning pin is inserted through the mounting plate, and the positioning pin is inserted and cooperated with the base. A retaining plate is arranged on the base, and an installation groove for slidingly cooperating with the retaining plate is provided on the base. A sand injection hole for filling sand into the retaining plate is provided on the retaining plate. A connecting plate is fixedly connected to the side surface of the retaining plate. A rotating plate is inserted through the side surface of the retaining plate away from the connecting plate. The rotating plates on adjacent retaining plates are inserted and cooperated with the connecting plate. A fixing component for fixing the connecting plate is arranged on the rotating plate. A rotating groove for slidingly cooperating with the rotating plate is provided on the retaining plate. A rotating rod is inserted through the retaining plate, and the rotating rod is inserted through the rotating plate and rotatably connected to the rotating plate. A locking component for locking the retaining plate is arranged on the base.

[0008] By adopting the above technical solution, the operator first installs the base, then the operator uses the positioning pins to fix two adjacent bases, the operator inserts the retaining plate into the installation groove, then the operator inserts the second retaining plate into the installation groove, and then the operator moves the second retaining plate. The movement of the retaining plate drives the movement of the moving plate, and the moving plate is inserted into the rotating plate of the adjacent retaining plate. Then the operator uses the fixing component to fix the connecting plate. After the operator installs the retaining plates in sequence, the operator then uses the locking component to lock multiple retaining plates. Finally, the operator injects sand into the retaining plate through the sand injection hole to increase the weight of the retaining plate, saving construction time. The setting of the rotating plate enables the angle between adjacent retaining plates to be adjusted, facilitating the use of the operator. The retaining plate is detachable, saving resources and facilitating the operator to recycle.

[0009] Preferably, a sliding groove for plugging and matching with the connecting plate is formed on the rotating plate. The fixing component includes a limiting rod passing through the top surface of the sliding groove, a limiting spring fixedly connected to the limiting rod. A limiting hole for plugging and matching with the limiting rod is formed on the connecting plate. A slope is arranged on the end of the limiting rod close to the connecting plate. A limiting groove for sliding and matching with the limiting rod is formed on the inner wall of the sliding groove. The end of the limiting spring away from the limiting rod is fixedly connected to the inner end surface of the limiting groove.

[0010] By adopting the above technical solution, the operator inserts the connecting plate into the sliding groove. When the connecting plate reaches the position of the limiting rod, the operator moves the connecting plate. The connecting plate slides on the slope of the limiting rod. At this time, the limiting rod slides in the limiting groove, and the limiting spring is in a compressed state. The operator continues to move the connecting plate. At this time, the limiting rod slides on the side wall of the moving plate. When the limiting rod moves to the position of the limiting hole, the limiting rod is inserted into the limiting hole under the action of the limiting spring, thereby fixedly connecting two adjacent retaining plates, facilitating the installation of the operator.

[0011] Preferably, the locking component includes a limiting plate passing through the base, a rotating column passing through the side of the retaining plate close to the base, and an arc plate fixedly connected to the rotating column. A locking groove for sliding and matching with the rotating column is formed on the inner bottom surface of the installation groove. An arc groove for sliding and matching with the limiting plate is formed on the arc plate. A driving component for driving the rotation of the rotating column is arranged on the rotating column.

[0012] By adopting the above technical solution, the operator inserts the retaining plate into the installation groove. At this time, the rotating column is inserted into the locking groove. Then, the operator uses the driving component to make the rotating column rotate. The rotation of the rotating column causes the arc plate to rotate to the position of the limiting plate. At this time, the limiting plate slides in the arc groove. The operator stops rotating the rotating column, and then locks the retaining plate.

[0013] Preferably, the driving component includes a first worm gear fixedly sleeved on the end of the rotating column far away from the base, a first worm shaft passing through the retaining plate, and a first bevel gear fixedly sleeved on the end of the rotating rod close to the base. The first worm gear meshes with the first worm shaft. A second bevel gear is fixedly sleeved on the end of the worm shaft far away from the rotating column. The second bevel gear meshes with the first bevel gear. A rotating component for driving the rotating rod to rotate is arranged on the rotating plate.

[0014] By adopting the above technical solution, the operator uses the rotating component to make the rotating rod rotate. The rotation of the rotating rod drives the first bevel gear to rotate. The rotation of the first bevel gear drives the second bevel gear to rotate. The rotation of the second bevel gear drives the first worm shaft to rotate. The rotation of the first worm shaft drives the first worm gear to rotate. The rotation of the first worm gear drives the rotating column to rotate, thereby locking the retaining plate.

[0015] Preferably, the rotating component includes a driving gear fixedly sleeved on the rotating rod and a driving rack installed at the end of the connecting plate far away from the retaining plate. The driving gear meshes with the driving rack. The width of the driving gear is greater than the width of the driving rack.

[0016] By adopting the above technical solution, the operator inserts the connecting plate into the rotating plate. The connecting plate drives the driving rack to move. The movement of the driving rack makes the rotating rod rotate, thereby driving the rotating column to rotate, and then locking the retaining plate to prevent the retaining plate from falling off. The width of the driving gear being greater than the width of the driving rack enables the operator, when disassembling, to simply lift the retaining plate, so that the limiting rod disengages from the limiting hole. Then, the operator moves the retaining plate to make the driving gear rotate in the reverse direction, thereby making the rotating column rotate and reset. Then, the operator lifts the retaining wall to separate the retaining wall from the base, which is convenient for the operator to disassemble and recycle, effectively saving resources.

[0017] Preferably, a threaded rod is inserted through the limiting plate. The threaded rod is in threaded cooperation with the limiting plate. A moving groove for slidingly cooperating with the limiting plate is formed on the inner side wall of the locking groove. A transmission component for driving the threaded rod to rotate is arranged on the base.

[0018] By adopting the above technical solution, the operator installs the retaining plate. Then, the operator uses the transmission component to rotate the threaded rod. The rotation of the threaded rod causes the limit plate to move, and the movement of the limit plate presses against the inner side wall of the arc-shaped groove, thereby fixing the retaining plate and improving the stability of the retaining plate.

[0019] Preferably, the transmission component includes a second worm gear fixedly sleeved on the threaded rod, a second worm shaft passing through the base, and a rotating shaft passing through the base. The second worm gear meshes with the second worm shaft. A third bevel gear is fixedly sleeved on the end of the second worm shaft close to the rotating shaft, and a fourth bevel gear is fixedly sleeved on the rotating shaft. The third bevel gear meshes with the fourth bevel gear.

[0020] By adopting the above technical solution, the operator rotates the rotating shaft. The rotation of the rotating shaft drives the fourth bevel gear to rotate. The rotation of the fourth bevel gear drives the third bevel gear to rotate. The rotation of the third bevel gear drives the second worm shaft to rotate. The rotation of the second worm shaft drives the second worm gear to rotate. The rotation of the second worm gear drives the threaded rod to rotate, thereby fixing the retaining plate and facilitating the operator's use.

[0021] Preferably, a plug rod is fixedly connected to the end face of the rotating shaft, and a slot for plugging and matching with the plug rod is opened on the end face of the rotating shaft away from the plug rod.

[0022] By adopting the above technical solution, the operator inserts the plug rod of the rotating shaft on the base into the slot of the rotating shaft of the adjacent base, so that the rotating shafts in the adjacent bases can rotate in the same direction at the same time, facilitating the operator to fix multiple groups of retaining walls.

[0023] Preferably, a sand outlet is opened on the side surface of the retaining plate, and a cover plate is installed on the sand outlet. The cover plate is hinged to the retaining plate, and a locking component for locking the cover plate is arranged on the retaining plate.

[0024] By adopting the above technical solution, when the operator locks the cover plate by using the locking component to prevent the sand in the retaining plate from flowing out, and the operator releases the locking state of the cover plate, the sand in the retaining plate can be discharged to reduce the weight of the retaining plate, which is beneficial for the operator to transport and install.

[0025] Preferably, the locking component includes a lapping plate hinged to the retaining plate, a rotating rod passing through the lapping plate, and a locking block fixedly connected to the cover plate. A fastening plate is fixedly connected to the end of the rotating rod close to the cover plate. A locking cavity is opened on the fastening block, and a groove for slidingly matching with the fastening plate is opened on the locking block. The groove communicates with the locking cavity.

[0026] By adopting the above technical solution, the operator overlaps the overlapping plate on the fastening block, and then the operator presses the knob. The movement of the knob causes the rotation rod to move, and the movement of the rotation rod causes the fastening plate to enter the locking cavity. Then the operator rotates the knob, and the rotation of the knob drives the fastening plate to rotate, so that the fastening plate is locked with the fastening block to prevent the cover plate from loosening.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The operator first installs the base, and then the operator uses the positioning pin to fix two adjacent bases. The operator inserts the retaining plate into the installation groove, and then the operator inserts the second retaining plate into the installation groove. After that, the operator moves the second retaining plate, and the movement of the retaining plate drives the moving plate to move. The moving plate is inserted into the rotating plate of the adjacent retaining plate. Then the operator uses the fixing component to fix the connecting plate. After the operator installs the retaining plates in sequence, the operator uses the locking component to lock multiple retaining plates. Finally, the operator injects sand into the retaining plate through the sand injection hole to increase the weight of the retaining plate, saving the construction time. The setting of the rotating plate enables the angle between adjacent retaining plates to be adjusted, facilitating the use of the operator. The retaining plate is detachable, saving resources and facilitating the operator to recycle.

[0029] 2. The operator inserts the connecting plate into the sliding groove. When the connecting plate reaches the position of the limiting rod, the operator moves the connecting plate. The connecting plate slides on the inclined surface of the limiting rod. At this time, the limiting rod slides in the limiting groove, and the limiting spring is in a compressed state. The operator continues to move the connecting plate. At this time, the limiting rod slides on the side wall of the moving plate.

[0030] 3. The operator inserts the retaining plate into the installation groove. At this time, the rotating column is inserted into the locking groove. Then the operator uses the driving component to rotate the rotating column. The rotation of the rotating column causes the arc-shaped plate to rotate to the position of the limiting plate. At this time, the limiting plate slides in the arc-shaped groove. The operator stops rotating the rotating column, thereby locking the retaining plate to prevent the rotating column from falling off.

[0056] The operator fills the cavity 28 with sand through the sand injection hole 25 to increase the weight of the high retaining plate 2, so as to achieve the effect of retaining soil by its own gravity. At the same time, the weight of the retaining plate 2 is reduced, which is convenient for the operator to transport the retaining plate 2. The operator overlaps the overlapping plate 81 on the locking block 83. At this time, the fastening plate 84 enters the groove 832. Then the operator presses the rotating rod 82 to make the fastening plate 84 enter the locking cavity 831. Finally, the operator rotates the rotating rod 82 to lock the overlapping plate 81 and the locking block 83 to prevent the cover plate 27 from loosening.

[0057] The implementation principle of a gravity retaining wall in an embodiment of the present application is as follows: The operator first digs a foundation pit, and then the operator sequentially places a plurality of bases 1 in the foundation pit and fixes the bases 1 by using the positioning pins 12. Then the operator inserts the first retaining plate 2 into the installation groove 14 and fixes it. Then the operator inserts the second retaining plate 2 into the installation groove 14. Then the operator slides the retaining plate 2 so that the connecting plate 21 is inserted into the rotating plate 22 and fixed by the limiting rod 31. The connecting plate 21 drives the rotating column 42 to rotate through the driving rack 62. The rotation of the rotating column 42 makes the limiting plate 41 enter the arc-shaped groove 45. And so on. The operator sequentially installs a plurality of retaining plates 2. Finally, the operator rotates the rotating shaft 73, and the rotating shaft 73 drives the limiting plate 41 to press down and abut against the arc-shaped plate 43 through the threaded rod 411, so as to fix the retaining plate 2. The cover plate 27 is locked through the overlapping plate 81. Finally, the operator injects sand into the cavity 28 through the sand injection hole 25 to increase the weight of the retaining plate 2, so as to achieve the effect of retaining soil by its own gravity, saving construction time, saving resources and facilitating the operator to recycle.

[0058] When the retaining wall needs to be disassembled, the operator first rotates the rotating rod 82 to release the locking state between the overlapping plate 81 and the locking block 83. Then, the operator opens the cover plate 27 to discharge the sand and soil inside the retaining plate 2. Then, the operator rotates the rotating shaft 73 to release the abutting state between the limiting plate 41 and the inner wall of the arc-shaped groove 45. Next, the operator lifts the retaining plate 2 to move the limiting rod 31 away from the connecting plate 21. Then, the operator moves the retaining plate 2 to move the connecting plate 21 away from the rotating plate 22. At this time, the driving rack 62 drives the rotating column 42 to reset through the driving gear 61, so that the operator can separate the retaining plate 2 from the base 1. By analogy, the operator sequentially removes multiple retaining plates 2. Finally, the operator pulls out the positioning pins 12 to remove multiple bases 1 at one time. The retaining plate 2 is detachable, which is convenient for the operator to recycle.

[0059] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
