Description

Technical Field

[0001] This utility model relates to a treatment structure, and more particularly to a treatment structure for steep slope engineering, belonging to the field of slope engineering structure design and construction technology. Background Technology

[0002] Terminology Explanation 1) Interception ditch: A ditch that intercepts water flowing down a slope to a lower slope or building and directs the water to a suitable location; 2) Slag retaining wall: A rigid structure with the function of blocking and preventing impacts on the upper slope of the protected object to prevent the slope from rolling stones and slag.

[0003] In slope treatment, interception and drainage measures are a crucial element, and their necessity is mainly reflected in the following aspects: 1) When groundwater or rainwater seeps into the slope, it increases the pore water pressure in the soil and rock mass, reduces the effective stress, weakens the shear strength, and easily triggers landslides or collapses. 2) The strength of soil and rock will decrease after they soften when exposed to water; drainage can reduce this risk. 3) Surface runoff from rainfall can erode slopes, forming gullies and damaging vegetation and slope protection structures.

[0004] In addition, for steep excavated slopes, there are usually large areas of natural slopes above that have not been human-intervened. These natural slopes may contain dangerous sources such as overburden and unstable boulders, which are prone to instability in the event of heavy rain or earthquakes, endangering the safety of buildings, personnel and equipment below.

[0005] In existing technologies, slope stabilization mainly focuses on intercepting surface water through drainage ditches to prevent landslides, while rockfall control primarily uses interception nets. Both methods are implemented separately, each fulfilling its own function. The problems with existing stabilization structures are that separate installations require separate foundations, increasing construction costs; furthermore, the separate installations offer limited functionality, and the wire mesh's interception effect is limited. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a treatment structure for high and steep slope engineering that has good treatment effect and can effectively intercept the downward flow of water and the falling danger source.

[0007] The technical solution adopted to solve the above-mentioned technical problems is: a treatment structure for high and steep slope engineering, including a high and steep slope, the treatment structure further including a slope excavation foundation, a slag-blocking and water-intercepting composite mechanism and a consolidation component, the slope excavation foundation is arranged at a specified position on the high and steep slope, the corresponding surface of the slag-blocking and water-intercepting composite mechanism seated on the slope excavation foundation is fixedly connected to the corresponding part of the slope excavation foundation through the consolidation component; the rolling stones above the slag-blocking and water-intercepting composite mechanism on the high and steep slope are blocked by the slag-blocking and water-intercepting composite mechanism at the corresponding position, and the surface water above the slag-blocking and water-intercepting composite mechanism on the high and steep slope is collected by the slag-blocking and water-intercepting composite mechanism at the corresponding position.

[0008] Furthermore, along the length of the slope, at least one set of drainage holes is sequentially installed in the slope excavation foundation below the bottom surface of the slag-blocking and water-intercepting composite structure. The lower ends of each drainage hole in the slope excavation foundation are located on the steep slope below the slag-blocking and water-intercepting composite structure, while the upper ends of each drainage hole in the slope excavation foundation are located on the bottom surface of the slag-blocking and water-intercepting composite structure.

[0009] The preferred method of the above scheme is to cover at least the excavation surface inside the slope excavation foundation that is not covered by the slag-blocking and water-intercepting composite mechanism with a concrete mesh spraying coating.

[0010] Furthermore, along the width direction, there are two sets of drainage holes arranged on the bottom surface of the slag-blocking and water-intercepting composite structure, with the front and rear sets of drainage holes staggered in position; along the slope direction, a concrete mesh spraying coating is also applied to the original slope surface above the excavated foundation within a specified range.

[0011] The preferred embodiment of the above scheme is that the slag-blocking and water-intercepting composite mechanism includes a slag-blocking wall and a water-intercepting ditch, which are arranged as a whole along the length of the slope on the excavated slope foundation.

[0012] Furthermore, the projection of the combined slag retaining wall and intercepting ditch in its cross section includes a slag retaining and water intercepting surface in the shape of the Big Dipper constellation and a slag retaining and water intercepting body connected behind the slag retaining and water intercepting surface. The slag retaining wall is composed of the handle surface in the shape of the Big Dipper constellation and the slag retaining and water intercepting body behind it. The intercepting ditch is composed of the concave bottom surface in the shape of the Big Dipper constellation and the slag retaining and water intercepting bodies behind and below it.

[0013] The preferred method of the above scheme is that the retaining wall and the intercepting ditch, which are combined into a whole, are made of concrete.

[0014] Furthermore, at least within a specified depth inside the slag-blocking and water-blocking body of the Big Dipper-shaped slag-blocking and water-blocking surface, there is a reinforced steel mesh.

[0015] The preferred embodiment of the above scheme is that the reinforcing steel mesh is composed of cross-sectional steel bars in the shape of the Big Dipper constellation and longitudinal steel bars extending along the length direction.

[0016] Furthermore, the consolidation components include vertical reinforcing bars and inclined reinforcing bars. The outer ends of the vertical reinforcing bars and inclined reinforcing bars are respectively embedded in the slag-blocking and water-cutting bodies at the corresponding locations. The other ends of the vertical reinforcing bars and inclined reinforcing bars are respectively inserted into the steep slope body below or behind the slope excavation foundation at the corresponding location.

[0017] The beneficial effects of this utility model are as follows: The technical solution provided in this application takes the steep slope requiring treatment as the treatment object. It constructs the treatment structure by adding a slope excavation foundation, a slag-blocking and water-intercepting composite mechanism, and a consolidation component. The slope excavation foundation is arranged at a designated location on the steep slope. Then, the corresponding surface of the slag-blocking and water-intercepting composite mechanism, which sits on the slope excavation foundation, is fixedly connected to the corresponding part of the slope excavation foundation through the consolidation component. In this way, boulders falling above the slag-blocking and water-intercepting composite mechanism on the steep slope can be blocked by the slag-blocking and water-intercepting composite mechanism at the corresponding location, and surface water above the slag-blocking and water-intercepting composite mechanism on the steep slope can be collected by the slag-blocking and water-intercepting composite mechanism at the corresponding location. This effectively treats the erosion damage caused by large amounts of downstream water flow on steep slopes and effectively blocks falling hazards on steep slopes, thereby significantly improving the treatment effect of steep slopes.

[0020] like Figure 1The diagram illustrates a treatment structure for steep slope engineering, providing effective control over downstream water flow and hazard sources. The structure includes a steep slope 1, a slope excavation foundation 2, a slag-blocking and water-intercepting composite mechanism, and a consolidation component. The slope excavation foundation 2 is positioned at a designated location on the steep slope 1. The corresponding surface of the slag-blocking and water-intercepting composite mechanism, mounted on the slope excavation foundation 2, is fixedly connected to the corresponding part of the slope excavation foundation 2 via the consolidation component. Rockfall on the steep slope 1 above the slag-blocking and water-intercepting composite mechanism is blocked by the corresponding slag-blocking and water-intercepting composite mechanism, and surface water on the steep slope 1 above the slag-blocking and water-intercepting composite mechanism is collected by the corresponding slag-blocking and water-intercepting composite mechanism. The technical solution provided in this application targets steep slopes requiring treatment. It constructs a treatment structure by adding a slope excavation foundation, a combined slag-blocking and water-intercepting mechanism, and consolidation components. The slope excavation foundation is positioned at a designated location on the steep slope. The corresponding surfaces of the slag-blocking and water-intercepting mechanism, which rests on the slope excavation foundation, are fixedly connected to the corresponding parts of the foundation via consolidation components. This allows for the interception of falling rocks above the slag-blocking and water-intercepting mechanism, and the collection of surface water above the mechanism. This effectively mitigates the erosion damage caused by large amounts of downstream water flow on steep slopes and effectively blocks potential hazards from falling water, thereby significantly improving the treatment effect of steep slopes. To maximize the drainage of seepage water into the steep slope and minimize its impact on the treatment structure, this application sequentially installs at least one set of drainage holes 3 along the slope length direction in the slope excavation foundation 2 below the bottom surface of the slag-blocking and water-intercepting composite structure. The lower ends of each drainage hole 3 in the slope excavation foundation 2 are located on the steep slope 1 below the slag-blocking and water-intercepting composite structure, while the upper ends are located on the bottom surface of the slag-blocking and water-intercepting composite structure. Furthermore, a concrete mesh sprayed coating 4 is applied to at least the excavation surface inside the slope excavation foundation 2 that is not covered by the slag-blocking and water-intercepting composite structure. Preferably, two sets of drainage holes 3 are arranged on the bottom surface of the slag-blocking and water-intercepting composite structure along the width direction, with the positions of the two sets staggered. A concrete mesh sprayed coating 4 is also applied to the original slope surface above the slope excavation foundation 2 within a specified range along the slope direction.

[0021] Accordingly, as a key structural improvement of the technical solution of this application, in order to effectively achieve the aforementioned inventive objectives while simplifying the structure of the slag-blocking and water-intercepting composite mechanism and the consolidation components to facilitate construction operations, the slag-blocking and water-intercepting composite mechanism of this application includes a slag-blocking wall and a water-intercepting ditch, which are arranged as a whole along the length of the slope on the excavated slope foundation 2. Preferably, the slag-blocking wall and water-intercepting ditch, as a whole, are constructed of cast concrete. Considering the stress characteristics of concrete structures, and to maximize the interception effect against rolling stones and even some debris flows, this application integrates a single slag retaining wall and intercepting ditch. The projection of this slag retaining wall and intercepting ditch across its cross-section includes a slag retaining and intercepting surface shaped like the Big Dipper constellation and a slag retaining and intercepting body 6 connected behind the slag retaining and intercepting surface. The slag retaining wall is composed of the handle surface 5 of the Big Dipper constellation and the slag retaining and intercepting body 6 behind it. The intercepting ditch is composed of the concave bottom surface 7 of the Big Dipper constellation and the slag retaining and intercepting bodies 6 behind and below it. More specifically, a reinforcing steel mesh 8 is embedded at least within the slag retaining and intercepting body at a specified depth inside the Big Dipper constellation slag retaining and intercepting surface. Preferably, the reinforcing steel mesh consists of cross-sectional steel bars 9 shaped like the Big Dipper constellation and longitudinal steel bars 10 extending along the length direction. The consolidation component includes vertical reinforcing bars 11 and inclined reinforcing bars 12. The outer ends of the vertical reinforcing bars 11 and inclined reinforcing bars 12 are respectively embedded in the slag-blocking and water-cutting body 6 at the corresponding positions. The other ends of the vertical reinforcing bars 11 and inclined reinforcing bars 12 are respectively inserted into the steep slope body below or behind the slope excavation foundation at the corresponding positions.

[0022] In summary, the technical solution provided in this application also has the following advantages: 1) It occupies little construction site, which is a significant advantage in steep slope engineering; 2) One structure achieves two functions, resulting in good economic efficiency; 3) It has a stable structure, complete functions, and a wide range of applications.

[0023] The technical solution of this application will be further described below through specific embodiments: The technical problem to be solved by this application is to provide a slope retaining wall structure with a water interception ditch function.

[0024] The technical solution adopted by this application to solve the above-mentioned technical problems is as follows: The slag retaining wall structure consists of four parts: reinforcing bars, drainage holes, the slag retaining wall and intercepting ditch structure, and shotcrete with wire mesh. Among them: 1) Part of the rock-inserting reinforcement bar is inserted into the rock mass, and the other part extends out of the rock mass, serving as a support and reinforcement bar for the retaining wall structure.

[0025] 2) Drainage holes extend from the bottom of the retaining wall to the lower slope to reduce water pressure on the foundation surface of the retaining wall structure during heavy rain.

[0026] 3) The retaining wall and intercepting ditch structure are cast as a whole with the rock-inserting reinforcement bars, and impact-resistant steel bars are arranged on the inner side of the slope. The bottom surface of the main structure of the retaining wall slopes inward to enhance its stability.

[0027] 4) The wire mesh and shotcrete are installed on the cleaned slope rock inside the intercepting ditch to prevent water from seeping out from the natural rock fissures as much as possible.

[0028] Example 1 The present invention will be further described below with reference to the accompanying drawings: like Figure 1 As shown in this application, a retaining wall structure with a water interception ditch function is constructed by excavating a construction space on a natural slope, pre-drilling drainage holes on the slope, arranging and embedding vertical and diagonal reinforcing bars, processing and installing reinforcing bars perpendicular to and along the water flow direction, erecting formwork, and then pouring concrete to form the retaining wall structure. Finally, shotcrete is applied to the inner side of the water interception ditch. The structure is stable, easy to construct, occupies little space, and is economical. It can form a water interception ditch and retaining wall on the outer side of steep slopes, effectively improving the safety of important structures below. It can be widely used in water conservancy and hydropower projects, railway and highway engineering, and other technical fields.

[0029] The drainage holes are spaced 2m apart, and geotextile can be installed at the hole openings for protection before concrete pouring. The spacing between the vertical and diagonal reinforcing bars is 50cm, which can be adjusted according to actual conditions during engineering application.

[0030] The spacing between the steel bars perpendicular to the water flow direction and the steel bars in the direction of water flow is 50cm, which can be adjusted according to actual conditions during engineering application.

[0031] The concrete retaining wall structure has a top width of 1m, a bottom width of 3m, and a height of 6m, which can be adjusted according to actual conditions during engineering application.
