Description

Technical Field

[0001] This utility model relates to the field of slope and landslide control and restoration technology. Background Technology

[0002] After slope instability occurs, landslides may happen, requiring the repair of the landslide-affected slope with an anti-slide structural system. Currently, commonly used repair techniques include anti-slide piles, frame beam structures, and retaining wall structures. Among them, the so-called frame beam structure refers to the implementation of prestressed anchor cables and concrete frame beams to enhance the overall integrity of the slope. It is often used for steep slopes. This structure has a very good repair effect, but it requires on-site concrete formwork and on-site pouring, resulting in a large amount of construction work and a long construction period.

[0003] To address these issues, some organizations have attempted to replace concrete frame beams with steel structures such as I-beams to improve construction speed. For example, Chinese Patent Publication 2016104371442 discloses a combined reinforcement method suitable for landslide control on non-coal open-pit mine slopes. However, in actual engineering projects, it has been found that the steel structures using this technology are prone to corrosion in the later stages. Even with appropriate anti-corrosion treatment, severe corrosion inevitably occurs after three years. Analysis reveals that this is due to the unique environment of the slope in the field. For instance, one of the main influencing factors is the high surface humidity at the slope location, leading to severe moisture accumulation near the I-beams. This, combined with the electrochemical corrosion system formed by the soil, rock, and steel structure, further accelerates the corrosion rate. Therefore, this technology has extremely unfavorable aspects. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a slope landslide treatment and repair system, which solves the problem of long construction cycles in existing slope landslide treatment technologies using concrete frame beam structures, aiming to improve construction speed while ensuring construction effectiveness.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A slope landslide control and repair system includes precast retaining wall components, precast retaining slab components, anchor cables, and partially cast-in-place modules. The system is characterized in that: the precast retaining wall components and precast retaining slab components are reinforced concrete precast parts; the precast retaining wall components have connecting bars at both ends along their length; the precast retaining slab components have connecting bars I and II at both ends, wherein connecting bar I is located at one end of the precast retaining slab component and is aligned with the length of the precast slab, and connecting bar II is located at the other end of the precast retaining slab component and is vertically positioned; the connection nodes of the precast retaining wall components and precast retaining slab components are connected by cast-in-place concrete to form partially cast-in-place modules, connecting the precast retaining wall components and precast retaining slab components in four directions (up, down, left, right) to form a frame structure; and the outer ends of the anchor cables are located within these partially cast-in-place modules.

[0007] The connecting steel bar I on the precast retaining wall component above the side is located within the local cast-in-place module.

[0008] The connecting steel bar II on the precast retaining wall component on the lower side is located within the local cast-in-place module.

[0009] The precast retaining wall components of adjacent retaining walls are connected by welding or sleeve connection and are located within the local cast-in-place module.

[0010] The height of the precast retaining wall components is controlled between 0.5 meters and 1 meter, and not exceeding 2 meters, to ensure the stability of the system.

[0011] The retaining wall prefabricated components have drainage holes prefabricated on the walls to allow for the release of static water pressure during rainy weather.

[0012] The precast retaining wall components are provided with bolt holes for installing aluminum templates, which are used to temporarily fix the aluminum alloy templates to facilitate the construction of the pouring system.

[0013] Furthermore, a reinforcing rib prefabricated block is fixedly installed at the right-angle overlap between the top of the prefabricated retaining wall component and the top prefabricated retaining plate component. The reinforcing rib prefabricated block is triangular, and the reinforcing rib prefabricated block and the prefabricated retaining wall component, as well as the reinforcing rib prefabricated block and the prefabricated retaining plate component, are fixedly connected with high-strength bolts to enhance the stability of the system before pouring.

[0014] Furthermore, the lower surface of the precast retaining wall component is provided with triangular ribs, which can be quickly inserted into the soil layer, thereby improving the stability of the precast retaining wall component.

[0015] The outer end of the anchor cable is located on the partially cast-in-place module, and the inner end is located in the deep soil layer of the slope, and the inner end is an enlarged anchor head.

[0016] The prefabricated retaining wall components have a trapezoidal stable cross-section.

[0017] The rectangular space formed by the prefabricated retaining wall components and prefabricated retaining slab components is equipped with deep-rooted plants, and is combined with three-dimensional geonets, fabrics, etc.

[0018] The prefabricated retaining wall components are I-shaped or C-shaped prefabricated components.

[0019] The beneficial effects of this utility model are:

[0020] This technology combines prefabricated retaining wall components and prefabricated retaining plate components. The prefabricated components are manufactured in the factory and assembled on site, combined with the on-site concrete pouring at the joints. This allows for the rapid construction of a slope landslide control and repair system, shortening the construction cycle. Compared with existing steel structure slope protection projects, it has the advantage of corrosion resistance.

[0021] In this technology, the precast retaining wall components can be made into straight, arc, or other irregular shapes to meet the requirements of different orientations in slope treatment. This is difficult to achieve in cast-in-place construction, which greatly improves the applicability of this technology. Attached Figure Description

[0034] 500 partially cast-in-place modules. Detailed Implementation

[0035] The slope landslide treatment and restoration system adopts a prefabricated construction method and combines anchor cables and pouring construction at local nodes to complete the construction of the entire frame structure. After the implementation of this technology, a planting area can be formed, and the root system of the plants can be used to further enhance the treatment effect of the slope and achieve the purpose of ecological restoration.

[0036] Specifically, the precast retaining wall components 100, precast retaining plate components 200, precast reinforcing rib blocks 300, anchor cables 400, and partially cast-in-place modules 500 are detailed in the instruction manual. Figure 1 To be continued Figure 6 The following is a detailed description of the composition, structure, and construction process of each part.

[0037] The precast retaining wall component 100 is a reinforced concrete precast part with a trapezoidal vertical surface that is smaller at the top and larger at the bottom. This precast retaining wall component is a gravity structure, and the trapezoidal structure is beneficial to the stability of the component. Both ends of the precast retaining wall component have connecting bars 110 along its length. These connecting bars are welded to adjacent precast retaining wall components or connected by sleeves to form an integral structure. During installation, the spacing between two adjacent precast retaining wall components is precisely controlled, forming local cast-in-place areas.

[0038] Furthermore, the height of the precast retaining wall component 100 is controlled between 0.5 meters and 1 meter, with a maximum height of no more than 2 meters, to ensure the stability of the system.

[0039] To address the issue of hydrostatic pressure buildup, drainage holes (not shown in the figure) are prefabricated on the walls of the aforementioned precast retaining wall components to release hydrostatic pressure during rainy weather.

[0040] A precast retaining slab component 200 is positioned perpendicular to the precast retaining wall component. Specifically, the precast retaining slab component is a flat precast slab made of reinforced concrete. Connecting reinforcing bars I 210 and II 220 are located at both ends of the precast retaining slab component 200. Connecting reinforcing bar I 210 is located at one end of the precast retaining slab component and runs parallel to the length of the precast slab. Connecting reinforcing bar II 220 is located at the other end, away from connecting reinforcing bar I, and is vertically positioned perpendicular to the length of the precast slab. Connecting reinforcing bar II is used to form the bottom formwork for the partially cast-in-place area below. Simultaneously, connecting reinforcing bar I 210 forms a side formwork in the partially cast-in-place area from the rear. Through the combination of the precast retaining slab components and the precast retaining wall component on all sides, and by setting an aluminum alloy formwork at the front, a partially cast-in-place area can be formed, and a partially cast-in-place module is formed by pouring concrete.

[0041] Furthermore, bolt holes are provided on the precast retaining wall component 100 for temporarily fixing the aforementioned aluminum alloy template, that is, temporarily fixing the aluminum alloy template to facilitate the construction of the pouring system.

[0042] Furthermore, in the right-angle overlap area between the top of the precast retaining wall component and the top precast retaining plate component, a reinforcing rib precast block 300 is also provided. The reinforcing rib precast block is triangular, and the reinforcing rib precast block and the precast retaining wall component, as well as the reinforcing rib precast block and the precast retaining plate component, are fixedly connected with high-strength bolts to enhance the stability of the system before pouring.

[0043] Furthermore, a triangular rib 230 is provided on the lower surface of the precast retaining wall component 200. The triangular rib can be quickly inserted into the soil layer, improving the stability of the precast retaining wall component. Of course, the triangular rib can also be omitted, which is within the protection scope of this utility model.

[0044] The outer end of the anchor cable 400 is located on the partially cast-in-place module 500, and the inner end is located in the deep soil layer of the slope, and the inner end is an enlarged anchor head.

[0045] In this technology, the trapezoidal stabilizing structure of the prefabricated retaining wall components can reduce the load on the upper part of the landslide and adjust the distribution of the slope's center of gravity, making it particularly suitable for soil slopes.

[0046] Furthermore, ecological vegetation is planted within the rectangular space formed by the aforementioned precast retaining wall components and precast retaining slab components. Specifically, deep-rooted plants (mainly shrubs) are selected in this area and combined with three-dimensional geonets, fabrics, etc., to stabilize the slope and improve the local erosion resistance.

[0047] Furthermore, the aforementioned prefabricated retaining wall components are I-shaped or C-shaped, meaning they can be customized with an arc shape according to the slope direction to meet diverse needs.

[0048] The construction process in this embodiment is as follows:

[0049] First, lines were marked and the ground surface was leveled at the landslide site, resulting in a stepped shape. Compaction was then carried out along the marked lines. Simultaneously, anchor cables were drilled and inserted. A crane was used to lift the precast components to the designated area. Then, the precast retaining wall and retaining plate components were erected horizontally and vertically, closely monitoring the enclosure of the cast-in-place areas during construction to ensure the outer ends of the anchor cables fell precisely into those areas. Next, the reinforcing rib precast blocks and aluminum alloy formwork were fixed in place, and finally, concrete was poured.

[0050] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Without departing from the spirit of the present utility model, all modifications and improvements to the present utility model by those skilled in the art should fall within the protection scope defined by the claims of the present utility model.
