Embodiment Construction
[0031] Such as Figure 1~3 As shown, a prefabricated highway soil slope reinforcement structure includes a prefabricated frame 1, a drainage anchor 2 and a composite protective layer 3, the composite protective layer 3 is covered on the slope surface, and the prefabricated frame 1 is press-fitted On the composite protective layer 3. The composite protective layer 3 plays the role of anti-scouring and greening on the slope surface, and the prefabricated frame 1 plays the role of stabilizing and protecting the composite protective layer 3 . The drainage anchor 2 is inserted into the pre-drilled anchor hole in the slope, and the end of the drainage anchor 2 is connected and fixed with the prefabricated frame 1. The drainage anchor 2 plays a drainage role on the one hand, and on the other hand provides a The tensile force makes the prefabricated frame 1 and the composite protective layer 3 more stable.
[0032] Preferably, the material of the prefabricated frame 1 is reinforced ...

The invention provides a prefabricated expressway soil slope reinforcing structure and a construction method thereof.The reinforcing structure comprises a prefabricated frame, drainage anchor rods and a composite protection layer, the composite protection layer covers the slope surface of a slope, the prefabricated frame is pressed on the composite protection layer, the drainage anchor rods are inserted into pre-drilled anchor holes in the slope, and the drainage anchor rods are inserted into the pre-drilled anchor holes in the slope; the end of the drainage anchor rod is fixedly connected with the prefabricated frame. The drainage anchor rod can effectively collect water in the slope body through the underground water collector, and the collected water is gradually discharged through the water absorption effect of the drainage fiber bundles, so that the slope is more stable. The composite protection layer comprises an anti-scouring layer, a middle vegetation soil layer and a water storage and fertilizer cultivation layer, and through the composite protection effect of the three layers, the effects of slope water and soil loss prevention, greening, attractiveness and the like are achieved.
Description
technical field [0001] The invention relates to the technical field of subgrade soil slope reinforcement, in particular to a prefabricated highway soil slope reinforcement structure and a construction method thereof. Background technique [0002] With the rapid growth of expressway mileage in my country, the number and length of expressway subgrades and cutting slopes are also increasing, and the stability of subgrades and cutting slopes is the basis for ensuring the safety and smoothness of expressways and driving safety. With the development and progress of the times, while the subgrade slope meets the engineering stability, the greening of the subgrade slope has gradually attracted people's attention. As an important part of expressway greening, the ecological protection of highway embankment slope is also of great engineering significance for preventing soil erosion and stabilizing roadbed. [0003] In order to reduce the impact of soil erosion and rainwater erosion on ...
