Technical Field
[0001] The present application relates to the field of geotechnical engineering technology, and in particular to a widening structure used in filling engineering. Background Art
[0002] Railways are an important part of my country's land transportation. With the accelerating pace of people's lives and the rapid development of society, people's demand for railway transportation is increasing, so it is necessary to expand the capacity of existing railways.
[0003] In the process of railway expansion, the widening of the fill roadbed is involved. Currently, steps are dug on the existing roadbed slope and then filled according to the width of the new roadbed, and the interface between the new and old slopes is reinforced, so that the connection between the new and old slopes is stable. However, when the height of the fill slope is high, the interface between the new and old slopes is long, so it is easy to have unstable connection between the new and old interfaces, which leads to a decrease in the safety and stability of the new roadbed, and thus affects the safety of railway operation.
[0004] With respect to the above-mentioned related technologies, the inventors believe that there is an unstable connection problem between the new and old interfaces of the high fill roadbed, which can easily reduce the safety and stability of the newly built roadbed. Utility Model Content

[0008] By adopting the above technical solution, one end of the horizontal baffle is set on the horizontal plane of the existing roadbed, so that the existing roadbed shares part of the vertical pressure on the horizontal baffle, thereby reducing the phenomenon that the newly built roadbed is separated from the existing roadbed due to vertical pressure. The setting of unidirectional geogrids, slope retaining walls and foot walls increases the slope stability of the newly built roadbed, thereby reducing the phenomenon of collapse or sliding of the newly built roadbed, thereby improving the safety and stability of the newly built roadbed. The setting of drainage ditches improves the drainage performance of the newly built roadbed and reduces the impact of rainwater accumulation on the stability of the newly built roadbed.
[0009] Optionally, both ends of the reinforcement rod are connected to reinforcement plates, and the reinforcement plates are arranged perpendicular to the reinforcement rod.

[0011] Optionally, the reinforcement rod is arranged perpendicularly to the new and old interfaces between the newly constructed roadbed and the existing roadbed.
[0012] By adopting the above technical solution, the vertical arrangement of the reinforcement rods and the new and old interfaces is beneficial to improving the reinforcement effect of the reinforcement rods on the newly built roadbed and reducing the slippage of the newly built roadbed at the new and old interfaces.
[0013] Optionally, there are multiple reinforcement rods, and a connecting rod is provided between two upper and lower adjacent reinforcement rods, and two ends of the connecting rod are respectively connected to the two upper and lower adjacent reinforcement rods.
[0014] By adopting the above technical solution, the connecting rod connects the upper and lower adjacent reinforcement rods, so that a whole structure is formed between the multiple first reinforcement components, which is beneficial to improve the overall stability of the new and old boundaries, and further improves the stability of the newly built roadbed.
[0015] Optionally, the second reinforcement assembly includes an anchor plate abutting against the slope retaining wall and an anchor rod arranged on the anchor plate, the anchor rod passes through the slope retaining wall and is inserted into the fill body, and the anchor rod is arranged perpendicular to the slope retaining wall.
[0016] By adopting the above technical solution, the anchor rods inserted into the built-up body and the anchor plates connected to the anchor rods improve the connection stability between the slope retaining wall and the built-up body, thereby improving the overall stability of the newly built roadbed.
[0017] Optionally, a reinforcement baffle is connected to one end of the anchor rod away from the anchor plate, and there are multiple reinforcement baffles, which are evenly distributed on the anchor rod.
[0018] By adopting the above technical solution, the setting of the reinforcement baffle increases the force-bearing area of the anchor rod, thereby improving the connection stability of the anchor rod to the slope retaining wall and the fill body, thereby further improving the overall stability of the newly built roadbed.
[0019] Optionally, the reinforcement baffle is arranged to be inclined, and the end of the reinforcement baffle away from the anchor rod is inclined toward the direction close to the anchor plate.
[0020] By adopting the above technical solution, the inclined reinforcement baffle further improves the reinforcement effect of the anchor rod, increases the connection stability between the reinforcement baffle and the anchor rod, and reduces the occurrence of breakage of the reinforcement baffle during the force process, thereby improving the service life and reinforcement effect of the reinforcement baffle.
[0021] Optionally, one end of the anchor rod away from the anchor plate is connected to a reinforcement vertical pile, and one end of the reinforcement vertical pile away from the anchor rod is inserted into the ground.
[0022] By adopting the above technical solution, the setting of the reinforced vertical piles reduces the slippage of the newly built roadbed, thereby further improving the stability and safety of the newly built roadbed.
[0023] In summary, this application has the following beneficial technical effects:
[0024] 1. The setting of horizontal baffles, one-way geogrids, slope retaining walls and foot walls increases the slope stability of the newly built roadbed, thereby reducing the collapse or sliding of the newly built roadbed, and further improving the safety and stability of the newly built roadbed;
[0025] 2. The setting of the reinforcement rod increases the stability of the new and old interfaces, the setting of the reinforcement plate increases the force-bearing area of the first reinforcement component, thereby improving the reinforcement effect of the reinforcement rod, and the setting of the connecting rod forms an integral structure between the vertically adjacent reinforcement rods, thereby further improving the connection stability between the new roadbed and the existing roadbed;
[0026] 3. The setting of anchor plates and anchor rods improves the connection stability between the slope retaining wall and the compacted body.

The retaining wall structure 1 includes a slope retaining wall 11 fixedly abutting against the slope of the newly built roadbed, a horizontal baffle 12 fixedly abutting against the top of the newly built roadbed, a one-way geogrid 13 fixedly arranged at the bottom of the newly built roadbed, a foot wall 14 fixedly arranged at one end of the slope retaining wall 11 away from the horizontal baffle 12, and a drainage ditch 15 adjacent to the foot wall 14, the horizontal baffle 12 is fixedly connected to the slope retaining wall 11, and the end of the horizontal baffle 12 away from the slope retaining wall 11 is laid on the horizontal plane of the existing roadbed.

[0034] Reference Figure 2 The first reinforcement assembly 3 includes a reinforcement rod 31, one end of which is inserted into the fill 2, and the other end is inserted into the existing roadbed. The reinforcement rod 31 is vertically arranged at the old and new interfaces of the existing roadbed and the newly built roadbed. Both ends of the reinforcement rod 31 are fixedly connected with reinforcement plates 32, and the reinforcement plates 32 are vertically arranged with the reinforcement rods 31. There are multiple reinforcement rods 31, and a connecting rod 33 is fixedly arranged between two upper and lower adjacent reinforcement rods 31, and the two ends of the connecting rod 33 are respectively fixedly connected with the two upper and lower adjacent reinforcement rods 31.
[0035] Reference Figure 3 The second reinforcement component 4 includes an anchor plate 41 fixedly abutted against the slope retaining wall 11 and an anchor rod 42 fixedly arranged on the anchor plate 41. The anchor rod 42 passes through the slope retaining wall 11 and is inserted into the compacted body 2. The anchor rod 42 is fixedly connected to the slope retaining wall 11 and the compacted body 2 respectively, and the anchor rod 42 is arranged vertically to the slope retaining wall 11.
