[0001] The utility model relates to the technical field of roadbed slope protection, in particular to a roadbed slope protection device. Background Art

[0002] The roadbed slope refers to the inclined surface where the two sides of the roadbed cross section connect to the ground. It can be divided into embankment slope and cutting slope. It is an important factor affecting the stability of the roadbed. In the roadbed structure, the shape and steepness of the slope have an important impact on the stability of the roadbed and the project cost. With the continuous development of social economy and the continuous construction of modern cities, large and small highways are constantly being built. The construction of highways has changed the way land is used on a large scale. As a result, landslide disasters are becoming increasingly serious. In order to prevent landslides and collapses of highway subgrades caused by rain, blockage of rivers and destruction of highways, it is necessary to set up protective devices on the roadbed slopes.

[0003] The existing slope protection device is not easy to install. After the protection column is embedded in the ground, a net hanging operation is required to cover the slope. However, it does not rule out the possibility of falling rocks on the covered slope surface. Therefore, when there are falling rocks on the covered slope surface, the existing device does not have good protection. Utility Model Content

[0006] Preferably, the protection net is internally slidably connected with an adapter, the side of the adapter is rotatably connected with an inner support rod, the side wall of the ground pile is provided with a side groove, and the inner support rod is movably clamped in the inside of the side groove.

[0007] Preferably, the top end of the adapter is rotatably connected to an internally threaded rod, the internally threaded rod is threadably inserted into the interior of the ground pile, and the top end of the internally threaded rod is fixedly connected to a special-shaped block.

[0008] Preferably, an outer rod is movably sleeved on the surface of the vertical rod, a plug is plugged into the bottom of the outer rod, and the plug is plugged into the vertical rod.

[0009] Preferably, a retaining net is vertically arranged on the upper surface of the protective net, a groove is opened on the side of the outer sleeve rod, the edge of the retaining net is embedded in the groove, and a cable tie is sleeved on the surface of the outer sleeve rod together with the edge of the retaining net.

[0010] Preferably, the top of the groove is fixedly connected to a mounting plate by bolts, the side of the mounting plate is rotatably connected to an oblique support rod, the bottom end of the oblique support rod is rotatably connected to a ground block, the surface of the ground block is plugged with a ground bolt, and the ground bolt is plugged into the ground.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By setting up a protective net, the ground pile is inserted into the roadbed slope, and the tool is clamped on the top of the internal threaded rod to drive the internal threaded rod to drive the adapter to move inside the ground pile. Since the inclined surface of the bottom end of the inner support rod matches the inclined surface of the bottom of the side groove, the inner support rod is expanded outward during the downward movement of the adapter, increasing the friction between the ground pile and the ground, so that the ground pile is more firmly inserted into the roadbed slope, and then the connecting plate and the flange plate are fixedly connected with bolts. At this time, the corners of the protective net can be sleeved on the surface of the vertical rod, and the threaded pressure plate is threaded to fix the corners of the protective net on the surface of the vertical rod, so that the protective net covers the surface of the roadbed slope to prevent gravel or soil on the roadbed slope from rolling down. The connection component of the device has a simple structure and is easy to install.

[0013] 2. By setting up a retaining net, the outer rod is sleeved on the surface of the vertical rod, and the outer rod and the vertical rod are fixedly connected by means of bolts. At this time, the edge of the retaining net is inserted into the inside of the groove, and the outer rod and the retaining net are fixedly connected by means of cable ties. At this time, the mounting plate is fixedly connected to the top of the outer rod by bolts, and the ground bolts are inserted through the plot into the ground. The outer rod is supported from the side by means of diagonal braces. At this time, the retaining net is vertically arranged with respect to the surface of the protective net. When there are rolling stones on the surface of the protective net, the retaining net can be used to block them, thereby improving the blocking effect against falling rocks and further enhancing the protectiveness of the protective device.
