Description

Technical Field

[0001] This application relates to a slope support structure with enhanced support function, and particularly to the field of civil engineering. Background Technology

[0002] In the process of civil engineering construction, slope protection plays a vital role in maintaining the stability of the geological conditions of the slope, preventing the risk of landslides, ensuring the safety of construction personnel, and serving as a prerequisite for the smooth implementation of the project.

[0003] Existing single-anchor slope support structures are mainly used in general clay and sandy soil areas. They rely primarily on the frictional resistance and tensile force dispersion of the single anchor to transfer the soil's own weight and external loads to the surrounding soil, reducing soil deformation and settlement, and providing support and fixation for the slope's geological layer.

[0004] However, existing technologies for slope support in general clay and sandy soil areas rely on single anchor rods for support, which have poor pull-out resistance. Utility Model Content

[0005] In order to overcome the problem of poor pull-out resistance of existing slope support structures used in general clay and sandy soil areas, this application provides a rock and soil slope support structure with the function of preventing soil erosion.

[0006] This application provides a slope support structure with enhanced support function, adopting the following technical solution:

[0007] An enhanced slope support structure includes anchor bolts, connecting beams, anchor bolt positioning plates, and anchor joints. Each anchor joint includes an anchor bolt positioning plate and multiple anchor bolts and connecting beams penetrating the positioning plate. These anchor joints are arranged in a grid pattern on the slope surface to be supported. Each pair of adjacent anchor joints is connected non-intersectingly by an integrally formed anchor bolt and connecting beam. In this embodiment, four anchor bolts are fixedly mounted on an anchor bolt positioning plate to form an anchor joint. The anchor joints are arranged in a grid pattern on the slope surface to be supported. The anchor bolts and connecting beams are integrally formed and connected at a 90° angle to connect two adjacent anchor joints without intersecting. Specifically, the anchor bolts and connecting beams between two adjacent anchor joints are integrally formed U-shaped steel bars. Pre-fabricated U-shaped steel bars are used to sequentially connect adjacent anchor bolt positioning plates, so that each anchor bolt positioning plate contains four steel bars. The steel bars embedded in the geological layer of the slope to be supported are the anchor bolts, and those tightly attached to the surface of the slope to be supported are the connecting beams.

[0008] By adopting the above technical solution, the pull-out resistance of the overall structure composed of four anchor bolts and anchor bolt positioning plates was improved, which effectively stabilized the geological conditions of the soil and rock slope. Simultaneously, the grid-shaped distribution of the anchor joints divided the slope to be supported into several sections, reducing the tension from the geological layer of the slope to be supported that each anchor bolt had to bear individually. This ensured the most basic safety protection requirements of the soil and rock slope support structure, guaranteeing the safety of construction personnel and the construction project.

[0009] Optionally, the anchor positioning plate is a carbon steel disc with a height of 25cm-30cm, and has four circumferentially arranged holes corresponding to the size and number of the anchor rods.

[0010] By adopting the above technical solution, any two adjacent anchor joints are connected by an anchor positioning plate, realizing an integral molding connection between the anchor rod and the connecting beam, which enhances the axial tensile force of the connecting beam.

[0011] Optionally, each anchor joint consists of four anchor rods and an anchor rod positioning plate for fixing and limiting the anchor rods, and the anchor rods are welded to the anchor rod positioning plate.

[0012] By adopting the above technical solution, the overall structural integrity of the anchor rod and the anchor rod positioning plate is enhanced. The anchor rod and the anchor rod positioning plate are fixed by welding, which eliminates the possibility of corrosion and loosening at the connection between the anchor rod positioning plate and the anchor rod. This ensures that each anchor rod can distribute the pressure from the geological structure of the rock and soil slope, and extends the service life of the slope support structure with enhanced support function proposed in this application.

[0013] Optionally, the anchor joint is flush with the surface of the slope to be supported, and a shallow-rooted herbaceous plant transplanting area is formed within the smallest square formed by the four anchor joints.

[0014] By adopting the above technical solution, the geological morphology of the slope surface to be supported will not be damaged, which is conducive to the subsequent transplantation of shallow-rooted herbaceous plants. The greening transplantation area can be used to transplant shallow-rooted herbaceous plants, quickly restore the greening ecology of the slope surface to be supported, reduce the weathering degree of the sandy slope surface, and reduce dust.

[0015] In summary, the slope protection structure with enhanced support function proposed in this application has at least one of the following beneficial effects:

[0016] 1. Significantly improved pull-out resistance and overall stability. Four anchor bolts are connected to the anchor bolt positioning plate. Through the synergistic action of multiple anchor bolts, the anchor bolt positioning plate is welded and fixed to the anchor bolts, completely preventing the anchor bolt positioning plate from rusting and slipping on the anchor bolts. The grid-shaped connecting beam design divides the slope to be supported into several sections, evenly distributing the tension of geological layer deformation in each section to the four anchor bolts, avoiding overload on any single section.

[0017] 2. The structure is easy to install. During construction, the prefabricated U-shaped steel bars are simply inserted along the openings on the anchor positioning plate to naturally form a connecting beam, eliminating the need for a secondary beam installation step in traditional processes. Furthermore, no additional fixing devices are required, significantly improving construction efficiency.

[0018] 3. It has good ecological restoration and long-term durability. Shallow-rooted herbaceous plants can be directly transplanted into the smallest square formed by four connecting beams, which can quickly restore the vegetation cover on the surface of the slope to be supported, reduce soil erosion and dust, and achieve a combination of engineering protection and ecological restoration.

[0023] The following is in conjunction with the appendix Figure 1 Appendix Figure 2 This application provides a further description of a slope support structure with enhanced support function.

[0024] Reference Figure 1 , Figure 2 This application discloses a slope support structure with enhanced support function, including a greening transplant area 1, a connecting beam 21, and anchor rods 22. There are four anchor rods 22, and they are fitted with anchor rod positioning plates 23, so that the relative positions of the anchor rods 22 are fixed by the anchor rod positioning plates 23.

[0025] The surface of the slope to be supported is initially leveled.

[0026] Drill holes at 90° along the surface of the rock and soil slope to be supported, using pneumatic dry drilling. The drilling angle should not exceed ±2° and the drilling depth should not be less than 4 meters. Drill until the hole reaches below the rock layer and should be drilled 50cm beyond the rock layer as the bottom sediment section. After the required depth is reached, drilling should be stopped for 1-2 minutes to prevent the bottom of the hole from collapsing or deforming.

[0027] Control the wind pressure to 0.2-0.4MPa. After using high-pressure air to remove all rock powder and water from the hole, drive the anchor positioning plate 23 into the hole along the drilling direction until the anchor positioning plate 23 is completely buried in the hole and flush with the surface of the slope to be supported.

[0028] The prefabricated U-shaped steel bars are slowly introduced into the anchor positioning plate 23, which is driven into two adjacent holes, so that the anchor 22 is fitted onto the anchor positioning plate 23 until it matches the drilling depth.

[0029] The connection between the anchor rod 22 and the anchor rod positioning plate 23 on the surface of the slope to be supported is fixed by welding to prevent the anchor rod positioning plate 23 from rusting and sliding on the anchor rod 22. The steel bars embedded in the borehole are the anchor rods 22, and the steel bars exposed on the surface of the slope to be supported and connecting two adjacent boreholes are the connecting beams 21.

[0030] The bottom-up grouting method was used to inject concrete grout along the borehole, and the time when the grout overflowed from the borehole opening was taken as the end time of grouting.

[0031] Using an isolation baffle slightly higher than the surface of the rock and soil slope 3 to be supported, a closed space is formed along the direction of the connecting beam 21, starting from the part where the anchor rod 22 is bent to connect the beam 21. Concrete grout is poured into the formed closed space, so that the outer surface of the grout after solidification can form a 3cm-5cm thick outer shell around the slope support structure with enhanced support function of this application.

[0032] Since the geological morphology of the surface of the rock and soil slope 4 to be supported has not been changed, after the concrete grouting and curing work is completed, shallow-rooted herbaceous plants are transplanted in the greening transplantation area 1 to accelerate the ecological restoration of the greening on the surface of the slope to be supported and reduce the sand blowing situation of the rock and soil slope 3 to be supported.

[0033] The implementation principle of this application is as follows:

[0034] The relative positions of the four anchor bolts 22 are locked on the anchor bolt positioning plate 23 to form a whole. Under the premise of ensuring uniform force distribution, the geological layer of the slope 3 to be supported is divided into several sections by means of the anchor bolts 22 and the connecting beam 21. This reduces the geological layer deformation tension exerted by any section of the geological layer on a single anchor bolt 22, and distributes the tension from the rock and soil slope 3 to be supported to each anchor bolt 22 of the slope support structure with enhanced support function of this application. This makes the anchor bolts 22 have stronger pull-out resistance, while ensuring that the deformation tension of the geological layer of the slope 3 to be supported does not exceed the support limit of the slope support structure with enhanced support function of this application.

[0035] The anchor rod 22 and the connecting beam 21 are integrally connected, which avoids secondary construction of the connecting beam 21 and eliminates the need for other stable connection methods to fix the connecting beam 21 and the anchor rod 22. This enhances the axial tensile force of the connecting beam and makes the construction process of the slope support structure with enhanced support function of this application simpler and more efficient.

[0036] Shallow-rooted herbaceous plants were transplanted between the grids formed by the connecting beams, making full use of the vegetation's sand-fixing and sand-preserving capabilities, reducing the weathering and erosion of the slope surface to be supported, and achieving a combination of engineering protection and ecological restoration, thereby preventing the risk of landslides on the slope to be supported.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
