Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of slope protection, in particular to a device for preventing road slope from collapsing during reconstruction and expansion. Background Art
[0002] With the rapid development of my country's road traffic infrastructure construction and the increasing number of existing road reconstruction and expansion projects, especially in the process of road construction under complex geological conditions such as mountainous and hilly areas, the issue of slope stability is particularly important. In the reconstruction and expansion operations such as widening of the original road or raising of the roadbed, due to the influence of excavation and backfilling operations, the original slope structure is seriously disturbed and the soil structure is damaged. In addition, due to the effects of rainwater erosion, groundwater activity and vehicle vibration, the slope is prone to deformation, instability and even collapse, which seriously affects the safe operation of the road and the surrounding environment.
[0003] In the prior art, although traditional slope protection measures, such as mortar-laid stone and concrete slope protection, provide support and stability to a certain extent, they are still difficult to effectively resist disasters such as landslides and collapses in specific geological environments, such as areas with soft soil, severe rock weathering, and abundant groundwater. Simple vegetation protection or passive protection nets cannot effectively prevent large-scale landslides caused by deep movement of soil. In addition, the inevitable construction disturbances in the renovation and expansion project, such as excavation and filling operations, further increase the risk of slope instability. At present, no effective solutions have been proposed for the problems in the relevant technologies. Therefore, it is necessary to propose a device for preventing the collapse of road slopes during renovation and expansion to solve the above-mentioned problems. Utility Model Content
[0004] In view of the problems in the related technology, the utility model proposes a device for renovating and expanding a road slope to prevent collapse, so as to overcome the above-mentioned technical problems existing in the existing related technology.
[0005] To this end, the specific technical solutions adopted by the utility model are as follows:
[0006] A device for preventing the side slope of a road from collapsing during reconstruction and expansion comprises a mud foundation, a roadbed is arranged above the mud foundation, a side slope is arranged on one side of the roadbed, a road surface is fixedly connected to the side slope and the roadbed, a transmission rod is arranged inside the roadbed, a support plate is fixedly connected to the top of the transmission rod, the support plate is fixedly connected to the road surface, a rotating shaft is rotatably installed on the surface of the transmission rod, a tightening rod is installed through the inside of the side slope, a rotating groove is provided at one end of the tightening rod, both ends of the rotating shaft are fixedly connected in the rotating groove, one end of the tightening rod passes through the side slope and is fixedly connected to a protective plate, a support block is fixedly connected to the surface of the tightening rod, and a blocking mechanism is fixedly installed on the surface of the support block.
[0007] Furthermore, in order to prevent the tightening rod from sliding toward the outside of the slope, the blocking mechanism includes a positioning rod fixedly connected to the surface of the support block, blocking plates are provided on both sides of the positioning rod, and rotating bearings are fixedly connected to both sides of the surface of the blocking plate. The rotating bearings are fixedly installed on the surface of the positioning rod, and a rotating limit plate is fixedly connected to the surface of one side of the blocking plate.
[0008] Furthermore, in order to plant grass and trees on the slope surface to reinforce the slope, planting grooves are opened on both sides of the protective plate.
[0009] Furthermore, in order to prevent water and soil erosion on the slope surface and to drain rainwater on the slope, a slope protection road is connected to the bottom of the slope, and a side ditch is opened on one side of the slope protection road.
[0010] Furthermore, in order to ensure that rainwater on the road surface and the slope can flow smoothly into the side ditch, the surface of the protective plate and the slope protection road are provided with flow grooves, and the ends of the flow grooves are connected to the side ditch.
[0011] Furthermore, in order to ensure the stability of the bottom of the slope, a load-bearing plate is fixedly connected to one side of the bottom surface of the slope, and an embedded anchor rod is fixedly connected to the bottom surface of the load-bearing plate.
[0012] Furthermore, in order to protect objects on the road surface, a guardrail is fixedly installed on the top surface of the slope.
[0013] The beneficial effects of the utility model are:
[0014] 1. Through the rotational connection between the transmission rod and the tightening rod, and the tightening rod is connected to the protective plate on the slope surface, when the road surface is under pressure, the pressure is transmitted to the transmission rod through the support plate. After the inclined transmission rod is under pressure, it gives the tightening rod a force to tighten toward the inside of the roadbed, so that the end of the tightening rod pulls the protective plate toward the slope to tighten, so that the supporting force of the protective plate on the slope surface is increased, effectively preventing the occurrence of landslides, collapses and other disasters on the slope surface.
[0015] 2. Through the blocking mechanism on the surface of the tightening rod, when the slope surface wants to push the protective plate outward and collapse, the two blocking plates on the blocking mechanism offset the thrust when the slope wants to collapse through the resistance generated by their own movement and the inside of the slope, thereby preventing the slope from collapsing. When the transmission rod pulls the tightening rod to move inside the roadbed to tighten the protective plate, the two blocking plates can be folded through their own rotating connection to reduce the resistance during tightening.
