Technical Field

[0001] The utility model relates to the technical field of roadbed retaining, in particular to a roadbed composite retaining structure. Background Art

[0002] The roadbed is a linear structure built with soil or stone. It bears its own rock and soil weight, the gravity of the road surface, and the vehicle load transmitted from the road surface. To ensure driving safety, the roadbed must have sufficient strength, stability and durability. Therefore, the support of the roadbed slope is particularly important. The common roadbed support structure is to set up several groups of retaining walls at the slope position of the roadbed.

[0003] At present, the existing retaining wall for roadbed support is made of bricks when in use, so its height is fixed. When the retaining height is not enough, the original retaining wall can only be dismantled and then a retaining wall with a new fixed height can be installed. Such operation is very inconvenient, time-consuming and labor-intensive, and will also prolong the construction period. For this reason, we propose a composite roadbed retaining structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 The top of the retaining wall 1 is provided with a bottom plate 2, and the top of the bottom plate 2 and the retaining wall 1 are respectively connected with an insertion block 3, and the front of the insertion block 3 is symmetrically connected with a positioning block 4. The insertion block 3 and the positioning block 4 connected on the upper side of the bottom plate 2 can be conveniently connected to the bottom retaining wall 1. The stability of the device during the supporting process can be effectively guaranteed by the arrangement of the bottom plate 2. The bottom end of the retaining wall 1 is provided with a docking groove 11 adapted to the insertion block 3 and the positioning block 4. The front of the bottom end of the retaining wall 1 is provided with a connecting frame 5, and the interior of the connecting frame 5 is provided with an installation mechanism. Through the arrangement of the installation mechanism, the retaining walls 1 can be quickly connected, thereby effectively improving the convenience of the device. In addition, in the process of transporting the device, the retaining walls 1 can be split to facilitate the transportation and storage of the staff. When carrying out the supporting operation, multiple groups of retaining walls 1 can be compositely installed to increase the height of the device, thereby achieving the purpose of comprehensive retaining.

[0023] Further, see Figure 1 and Figure 2 It can be known that support rods 16 are evenly distributed on the bottom end of the base plate 2, and the support rods 16 are arranged in a conical structure. Contact grooves 12 are equidistantly provided on the back of the retaining wall 1. The stability of the retaining wall 1 placed on the ground can be effectively guaranteed by using multiple groups of support rods 16 arranged in a conical structure. Combined with the arrangement of the contact grooves 12, the contact area between the retaining wall 1 and the foundation slope can be effectively increased, thereby further improving the reliability of the device during use.

[0024] Further, see Figure 2 and Figure 3It can be known that the mounting mechanism includes a bevel gear set 6, which is mounted at the center of the connecting frame 5. A rotating rod 7 is inserted on the front of the bevel gear set 6, and the rotating rod 7 extends to the front of the connecting frame 5. Threaded rods 8 are symmetrically inserted on both sides of the bevel gear set 6, and the ends of the threaded rods 8 that are away from each other are connected to the inner wall of the connecting frame 5 through bearings. Moving blocks 9 are respectively sleeved on the outer sides of the threaded rods 8, and both sides of the moving blocks 9 are connected to mounting rods 10. The other end of the mounting rod 10 extends to the outside of the connecting frame 5. A limiting groove compatible with the mounting rod 10 is opened inside the positioning block 4. The two sets of threaded rods The threads of the rod 8 are in opposite directions, so when the rotating rod 7 rotates, the mounting rods 10 on the left and right sides can be driven to move in opposite directions. In addition, a threaded groove compatible with the threaded rod 8 is provided inside the moving block 9, so that the moving block 9 can be driven to slide in the internal cavity of the connecting frame 5. The bevel gear set 6 is composed of three sets of bevel gears, and the three sets of bevel gears are respectively fixedly mounted on the ends of the two sets of threaded rods 8 and the outside of the rotating rod 7, and the three sets of bevel gears are connected to the inner wall of the connecting frame 5 through bearings. Through the setting of the three sets of bevel gears, the two sets of threaded rods 8 can be driven to rotate in the opposite direction when the staff rotates the rotating rod 7.

[0025] Further, see Figure 2 It can be seen that the moving block 9 is set as a rectangular structure, and the outer surface of the moving block 9 is tightly fitted with the inner wall of the connecting frame 5. By matching the moving block 9 with the inner wall of the connecting frame 5, the guiding work of the mounting rod 10 can be achieved to prevent the moving block 9 from idling.

[0026] Further, see Figure 3 and Figure 4 It can be known that the side of the retaining wall 1 is connected with a positioning rod 13, and the positioning rod 13 is distributed at the four face angles of the bottom end of the retaining wall 1. The top of the retaining wall 1 and the base plate 2 are provided with a slot that is compatible with the positioning rod 13. Through the mutual cooperation of the four groups of positioning rods 13 and the slots, the retaining wall 1 can be pre-positioned to facilitate subsequent installation.

[0027] Further, see Figure 4 It can be seen that a rubber ring 14 is symmetrically sleeved on the outer side of the positioning rod 13, and the longitudinal section of the rubber ring 14 is set as an arc structure. The inner wall of the groove and the outer surface of the rubber ring 14 are tightly fitted. The rubber ring 14 set by the arc structure can improve the pre-positioning effect of the retaining wall 1.

[0028] Further, see Figure 3 It can be known that a docking plate 15 is connected to the upper side of the connecting frame 5, and the docking plate 15 is connected to the front side of the retaining wall 1 through bolts. Through the cooperation between the docking plate 15 and the bolts, the retaining wall 1 and the connecting frame 5 can be docked and disassembled, thereby facilitating the staff to replace the damaged connecting frame 5.

[0029] Working principle: When the utility model is used, the staff can first place the retaining wall 1 at the side slope of the roadbed, and then insert the docking groove 11 opened at the bottom end of the bottom plate 2 into the outside of the insertion block 3 and the positioning block 4. At this time, the positioning rod 13 and the rubber ring 14 connected to the bottom end of the bottom plate 2 can be inserted into the card slot to realize the pre-positioning of the retaining wall 1. Then the staff can rotate the rotating rod 7 to drive the rotation of the bevel gear set 6 to drive the reversing rotation of the two sets of threaded rods 8. At this time, the threaded rod 8 can be threadedly matched with the moving block 9, so that the moving block 9 is inside the connecting frame 5. The mounting rod 10 connected to the side of the moving block 9 is inserted into the limiting groove provided inside the positioning block 4, thereby achieving docking between the retaining wall 1 and the base plate 2. Then the staff can engage a new set of retaining walls 1 on the upper side of the retaining wall 1, and achieve docking between the retaining walls 1 by repeatedly rotating the rotating rod 7. Then the staff can use anchor bolts to position the retaining wall 1 and the base plate 2 on the slope of the foundation for fixing. When the retaining height of the device is not enough, it can be achieved by simply increasing the number of retaining walls 1. The above is the entire working principle of the utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.
