Embodiment Construction
[0018] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0019] Depend on Figure 1 to Figure 3 A slope protection structure is given, including prestressed anchor rods 1, frame beams 2, and stepped anchor holes 10 set on the slope. The beam and multiple longitudinal beams are vertically intersected, and the intersection of the beam and the longitudinal beam is provided with a construction anchor hole 3, and the outer end of the prestressed anchor rod 1 is fixed in the construction anchor hole 3 to anchor the frame beam 2 on the slope. The inner end of the stress anchor rod 1 is welded with a circular bearing plate 4 perpendicular to it. The bearing plate 4 is equipped with a first gear 5 and a plurality of second gears 6 whose circumferences are evenly distributed outside the first gear 5. The second gear 6 is meshed with the first gear 5, and the first gear 5 is fixedly con...

The invention relates to a slope protection structure and a construction method thereof. The problem that a prestressed anchor rod frame beam is prone to suffer anchor head looseness and prestress loss is effectively solved. According to the technical scheme, a special reaming tool is adopted to drill multiple-section step holes on a slope, a variable-diameter bearing plate is installed at the bottom of an anchor rod, after the anchor rod is inserted into the step hole, the diameter of the bearing plate is enlarged, then grouting is conducted to increase bearing capacity, slurry is formed by mixing old sweater fiber and concrete and can be fully combined with surrounding rock mass, so that friction force is improved, cracks generated in a cement slurry solidification process is effectivelyreduced, and a reserved anchor hole is formed in the frame beam for later secondary reinforcement of the frame beam. According to the structure, the anchor bearing capacity can be effectively improved, secondary reinforcement can be carried out, and the long-term stability of the slope protection structure can be effectively guaranteed.
Description
technical field [0001] The invention relates to the technical field of road and railway slope protection, in particular to a slope protection structure and a construction method thereof. Background technique [0002] With the rapid development of my country's engineering construction, project builders are faced with more and more high cutting slopes, coupled with the complex geological conditions in mountainous areas, high cutting slopes, climate change and other factors, the stability of high slopes The problem of safety is becoming more and more prominent. In order to ensure the safety of high cutting slopes, we have adopted a variety of protection technologies for high cutting slopes. Usually, soil nail walls and prestressed anchor frame beams are used to reinforce the slopes. . [0003] Prestressed anchor frame beam is an effective method for prevention and protection of high cutting slope diseases. This technology can not only resist the disease and damage of deep rock m...
