[0028] The embodiment of the present application discloses a highway retaining wall that is easy to replace and splice.
[0029] Reference Figure 1-3 A highway retaining wall that is easy to replace and splice, comprising a retaining wall plate 1, a connecting component 2 and an embedded component 3, wherein the retaining wall plate 1 and one end of the connecting component 2 are detachably mounted, and the other end of the connecting component 2 and the embedded component 3 are detachably fixedly mounted, and the lower end of the embedded component 3 is buried in the ground;
[0030] When in use, the embedded component 3 is fixed on the ground by burying it with concrete, and then one end of the connecting component 2 is fixedly installed with the retaining wall plate 1. After installation, the other end of the connecting component 2 is fixed to the embedded component 3. By splitting the highway retaining wall into the retaining wall plate 1, the connecting component 2 and the embedded component 3, it is effective to facilitate the replacement of locally damaged parts after a collision of the highway retaining wall, thereby improving the efficiency of maintenance and reducing the cost of replacement.
[0031] Reference Figure 1-3 The connecting assembly 2 includes a mounting rotating block 21, a lifting column 22, a fixing column 23, a locking screw 24 and a locking nut 25. One end of the mounting rotating block 21 is fixedly connected to the baffle plate 1 by a screw, and the other end of the mounting rotating block 21 is rotatably connected to the top of the lifting column 22. The lifting column 22 is sleeved on the top of the fixing column 23. The locking screw 24 passes through the top of the fixing column 23, and both sides of the locking screw 24 are slidably arranged on the side walls of the lifting column 22. The locking nut 25 is threadedly connected to both ends of the locking screw 24, and the locking nut 25 is tightly pressed against both ends of the lifting column 22.
[0032] When in use, the end of the mounting rotating block 21 fixed to the baffle plate 1 is tightened and fixed by multiple screws, and the fixing column 23 is fixedly connected to the connecting seat 32 below through the flange. Then the lifting column 22 is sleeved on the fixing column 23, and the locking screw 24 is inserted into the fixing column 23 through the side wall of the lifting column 22 in turn. Then, the locking nut 25 is tightened to make the nut abut against the outer wall of the lifting column 22, so that the lifting column 22 is pressed against the fixing column 23.
[0033] Reference Figure 1-2 In a more specific implementation manner, a latch tooth 221 is provided on the side wall of the lifting column 22, and a latch plate 26 is provided between the locking nut 25 and the lifting column 22, and the nut abuts against the latch plate 26. When in use, the locking nut 25 can abut against the latch plate 26, and the relative fixation between the lifting column 22 and the fixed column 23 can be firmly ensured through the latch connection between the latch plate 26 and the latch tooth 221.
[0034] Reference Figure 1-2, a tightening assembly 4 is also provided on both sides of the lifting column 22, and the tightening assembly 4 includes a fixing plate 41, a bolt 42 and an abutment block 43. The fixing plate 41 is fixed to the side wall of the lifting column 22, and the bolt 42 is threadedly connected to the fixing plate 41. The abutment block 43 is fixedly arranged at the end of the bolt 42. When in use, after the baffle plate 1 is installed, by rotating the bolt 42 to tighten the abutment block 43 against the inner wall of the baffle plate 1, the baffle plate 1 can be effectively prevented from flipping over during use, while ensuring the stability of the baffle plate 1 during collision.
[0035] Reference Figure 1-3 The embedded component 3 includes an embedded plate 31 and a connecting seat 32. The embedded plate 31 is buried in the ground, and the connecting seat 32 is fixedly connected to the fixing column 23 through a flange;
[0036] More specifically, a plurality of barbs 33 are fixedly disposed at the bottom of the embedded plate 31. The barbs 33 prevent the embedded plate 31 from easily coming off the ground when a collision occurs, thereby reducing the need to replace the embedded plate 31 during maintenance.
[0037] More specifically, a plurality of reinforcing plates 34 are provided between the embedded plate 31 and the connecting seat 32 to enhance the stability between the embedded plate 31 and the connecting seat 32;
[0038] When in use, the embedded plate 31 is buried in the ground and covered with concrete. After cooling, the fixing column 23 and the connecting seat 32 are connected through a flange.
