Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and in particular to a drainage and dredging structure for a slope in a poor environment. Background Technology

[0002] Slopes are common engineering geological structures, widely present in infrastructure construction such as highways, railways, and water conservancy projects. For some special "adverse environment slopes," such as those with loose soil, poor vegetation cover, or located in areas prone to heavy rain and debris flows, their stability is often poor, making them highly susceptible to soil erosion and even landslides.

[0003] While existing slope protection and drainage technologies can address general runoff issues, they remain significantly inadequate when facing sudden, high-intensity water flow impacts on slopes in adverse conditions. Most drainage ditch structures, such as stepped or masonry structures, while diverting water flow, lack effective mechanisms to reduce and buffer the kinetic energy of the flow. When the flow rate and velocity are high, the high-energy water directly impacts the drainage ditch structure and the slope toe soil, easily damaging the structural integrity of the ditch itself and exacerbating erosion and scouring at the slope toe, ultimately leading to further slope instability. Simultaneously, existing slope stabilization structures, such as lattice beams or certain protective nets, often fall short in achieving a balance between physically blocking sediment and allowing water infiltration into the slope (i.e., reducing pore water pressure), making it difficult to simultaneously cope with the dual threats of high-energy water flow erosion and increased internal water pressure.

[0004] Therefore, this utility model proposes a drainage and dredging structure for adverse slopes to solve the problems of existing technologies lacking an effective step-by-step energy reduction and buffering mechanism when dealing with high-intensity water flow impacts on adverse slopes, and the insufficient synergy between slope stabilization and drainage functions. Utility Model Content

[0005] In view of the problems in the existing technology of drainage and dredging structures for slopes in adverse conditions, such as the lack of effective step-by-step energy reduction and buffering mechanisms, which leads to large water flow impact force and easy severe soil erosion, as well as insufficient coordination between slope stabilization and drainage functions, this utility model aims to provide a drainage and dredging structure for slopes in adverse conditions with improved structure that can effectively solve the above problems.

[0006] This utility model provides a drainage and dredging structure for adverse slopes, including a drainage ditch and a mounting frame fixedly connected to both sides of the drainage ditch. The structure is mainly used to collect water flow and serve as the main installation body.

[0007] The structure also includes a hydrophobic buffer component and an anti-slide component, which are used to reduce the energy of water flow and physically stabilize the slope.

[0008] The hydrophobic buffer assembly includes a connecting strip, a base, a hydrophobic shuttle block, and a buffer block. The connecting strip is fixedly connected between two mounting crossbeams, and is perpendicular to the crossbeams, providing support. The base has a shuttle-shaped structure and is fixedly connected to the top of the connecting strip, used for initial diversion of the water flow. The hydrophobic shuttle block, also a shuttle-shaped structure, is fixedly connected to the top of the base, used to cooperate with the base to further divert larger water flows, reducing impact force. The buffer block has a semi-cylindrical structure and is fixedly connected to the mounting crossbeams, used for final buffering and guiding of the diverted water flow.

[0009] The anti-slide component includes a wire mesh, screws, circular grooves, and screw holes. The wire mesh is a mesh structure laid on the surface of the mounting frame; the circular grooves are formed on the surface of the wire mesh; the screw holes are formed on the mounting frame; the screws pass through the circular grooves and are threaded into the screw holes, thereby detachably fixing the wire mesh to the mounting frame, achieving the interception of mud and sand and the penetration of water into the slope.

[0010] Preferably, the drainage ditch extends along the slope direction, and the mounting frame is arranged parallel to the length of the drainage ditch to adapt to the slope terrain and ensure the continuity of the installation foundation.

[0011] Preferably, the hydrophobic shuttle block is vertically aligned with the base, and the tip of the hydrophobic shuttle block faces the direction of the water flow to achieve the best water diversion effect.

[0012] Preferably, the arc surface of the buffer block faces the direction of the water flow, and the buffer block is located downstream of the water flow of the base and the water-repellent shuttle block, ensuring that the water flow can be smoothly buffered.

[0013] Preferably, the wire mesh structure is permeable, allowing water to seep out while blocking mud and sand, thereby reducing the pore water pressure inside the slope.

[0014] Preferably, the circular grooves are distributed along the edge of the wire mesh, and the screw holes correspond one-to-one with the positions of the circular grooves, which facilitates positioning and installation.

[0015] Preferably, the two ends of the connecting strip are welded and fixed to the inner sidewalls of the two side mounting frames, which improves the connection strength and overall stability of the structure.

[0016] Preferably, multiple sets of the hydrophobic buffer components are arranged at intervals along the length of the drainage channel to achieve continuous buffering of long-distance water flow.

[0017] Preferably, the diameter of the screw nut is larger than the diameter of the circular groove, which is used to effectively compress the wire mesh when tightening the screw to ensure the firmness of the fixation.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, by setting a double diversion structure consisting of a spindle-shaped base and a hydrophobic shuttle block, as well as a semi-cylindrical buffer block, achieves the gradual reduction and buffering of the impact force of water flow, effectively solving the problem that excessive impact force of large water flow in the prior art can easily cause serious soil erosion and structural damage, and achieves the effect of significantly reducing soil erosion and protecting slopes and drainage structures.

[0020] 2. This utility model, by setting up a mesh-like steel wire mesh, achieves the dual functions of physically intercepting and blocking mud, sand and gravel, and allowing water to seep out. It effectively solves the problems of unstable soil, high pore water pressure and easy landslides on slopes in adverse conditions, and achieves the technical effect of stabilizing the slope and soil and enhancing the safety of the slope.

[0021] 3. This utility model solves the problem of inconvenient maintenance and replacement of existing slope protection structures by using a detachable fixing method of screws passing through the circular groove and threaded into the screw hole to install the wire mesh, achieving the technical effect of simple structure, firm installation and convenient later maintenance operation.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 3 This utility model provides a drainage and dredging structure for adverse slopes, which aims to solve the structural defects of adverse slopes in the prior art, such as large water flow impact force, easy soil erosion and slope instability.

[0030] like Figure 1 and Figure 2 As shown, the drainage and diversion structure of this adverse slope includes a drainage channel 1 and mounting frames 2 fixedly connected to both sides of the drainage channel 1. The drainage channel 1 extends along the slope's inclination direction, serving as a basic platform for collecting and diverting slope runoff. The mounting frames 2, serving as the installation framework for the entire drainage structure and the anti-slide component 4, are arranged parallel to the length of the drainage channel 1, and there are two of them. The main functional components of the structure include a drainage buffer component 3 and an anti-slide component 4, both of which are mounted on the mounting frames 2.

[0031] The hydrophobic buffer assembly 3 is the core innovative structure of this utility model, used to divert and buffer water flow in stages to reduce the impact force of the water flow and thus reduce soil erosion. It includes a connecting strip 304, a base 303, a hydrophobic shuttle block 302, and a buffer block 301. The connecting strip 304 is fixedly connected between two mounting crossbeams 2, and the connecting strip 304 is distributed at right angles to the mounting crossbeams 2. The two ends of the connecting strip 304 are welded and fixed to the inner sidewalls of the two mounting crossbeams 2 respectively, providing support for the upper shuttle block assembly.

[0032] The base 303 is fixedly connected to the top of the connecting strip 304. The base 303 has a spindle-shaped structure and is mainly used to divert water flow when the flow is small, reducing the impact on the slope. A drainage shuttle block 302 is fixedly connected to the top of the base 303. The drainage shuttle block 302 also has a spindle-shaped structure and is used to further divert the high-speed water flow when the flow is large, in conjunction with the base 303, to more efficiently reduce the impact of the water flow. The drainage shuttle block 302 is vertically aligned with the base 303, with its tip facing the direction of the water flow. A buffer block 301 has a semi-cylindrical structure and is fixedly connected to the mounting frame 2. The arc surface of the buffer block 301 faces the direction of the water flow and is located downstream of the drainage shuttle block 302 and the base 303. It provides a final smooth buffer after the water flow is diverted by the base 303 and the drainage shuttle block 302, ensuring that the water flows smoothly and steadily into the drainage channel 1. Multiple sets of the hydrophobic buffer components 3 are arranged at equal intervals along the length of the mounting frame 2 to continuously buffer long-distance water flow in stages.

[0033] The anti-slide component 4 is another core innovative structure, set on two mounting crossbeams 2. It physically blocks mud, sand, and rocks while allowing water penetration. It includes a wire mesh 401, screws 402, circular grooves 403, and screw holes 404. The wire mesh 401 is laid on the surface of the mounting crossbeams 2. The surface of the wire mesh 401 has a mesh structure, which is permeable, allowing water from the soil to seep out while effectively trapping mud, sand, and gravel to prevent landslides. Circular grooves 403 are formed in the wire mesh 401, and screw holes 404 are formed in the mounting crossbeams 2. The screw holes 404 correspond one-to-one with the circular grooves 403. Screws 402 pass through the circular grooves 403 and are threaded into the screw holes 404. Tightening the screws 402 secures the wire mesh 401 to the mounting crossbeams 2, while loosening and removing the screws 402 allows for easy disassembly and maintenance of the wire mesh 401.

[0034] To explain the core technologies of this solution in more detail, please refer to the following references. Figure 1 and Figure 2 The internal structure and synergistic relationship of the hydrophobic buffer component 3 are described in detail below:

[0035] The purpose of setting up the hydrophobic buffer component 3 is to provide a multi-stage water flow energy dissipation mechanism. It is composed of multiple sub-components working together, including the connecting strip 304, the base 303, the hydrophobic shuttle block 302, and the buffer block 301.

[0036] The connecting strip 304 serves as a support structure, with its two ends fixedly connected between the inner sidewalls of two oppositely arranged mounting crossbeams 2. The connecting strip 304 is perpendicular to the mounting crossbeams 2, and the connecting strip 304 provides a stable mounting platform for the subsequent mounting base 303.

[0037] The base 303 is fixedly connected to the top of the connecting bar 304. The specific structure of the base 303 is a spindle-shaped structure. This streamlined structure enables it to smoothly divert the water flow to both sides when facing the water flow, and is mainly used to achieve initial impact reduction under the condition of small water flow.

[0038] The hydrophobic shuttle block 302 is fixedly connected to the top of the base 303. The hydrophobic shuttle block 302 is also constructed as a shuttle-shaped structure, with its tip facing the direction of water flow. The hydrophobic shuttle block 302 and the base 303 are aligned in the vertical direction. When encountering a large water flow, the water flow first impacts the hydrophobic shuttle block 302, and the hydrophobic shuttle block 302 achieves efficient secondary diversion, thereby forming a double diversion structure with the base 303, which greatly reduces the kinetic energy of the water flow.

[0039] The buffer block 301 is fixedly connected to the mounting frame 2, specifically to the upper surface of the mounting frame 2. The buffer block 301 is constructed as a semi-cylindrical structure with its arc surface facing the direction of water flow. The buffer block 301 is located downstream of the base 303 and the drainage shuttle block 302 in the direction of water flow. The buffer block 301 is used to receive and buffer the water flow after it has been processed by the aforementioned diversion structure, so that its energy can be further released. At the same time, its smooth semi-cylindrical curved surface ensures that the water flow will not stagnate here, but will be smoothly guided and eventually flow into the drainage channel 1 below.

[0040] The entire hydrophobic buffer assembly 3, through the structural combination and specific arrangement of the connecting strip 304, the shuttle-shaped base 303, the shuttle-shaped hydrophobic shuttle block 302 and the semi-cylindrical buffer block 301, forms a complete multi-stage diversion and buffering system, realizing effective guidance from the impact of high-energy water flow to the smooth inflow of low-energy water flow.

[0041] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0042] In a preferred embodiment, in order to adapt to the sloping terrain of the adverse environment slope and ensure the stability of the overall structure's installation foundation, the drainage ditch 1 extends along the sloping direction of the slope, and the number of installation crossbeams 2 is two. The two installation crossbeams 2 are fixedly connected to both sides of the drainage ditch 1 in parallel and extend along the length of the drainage ditch 1, thereby providing continuous installation support for the anti-slide component 4 and the drainage buffer component 3.

[0043] As another preferred embodiment, in order to improve the connection strength to resist water flow impact, the two ends of the connecting strip 304 are fixed to the inner sidewalls of the two mounting crossbars 2 by welding. The hydrophobic shuttle block 302, the base 303 and the connecting strip 304 are preferably made of metal to enhance the impact resistance and durability of the overall structure.

[0044] As another preferred embodiment, in order to achieve continuous and gradual buffering of long-distance slope runoff, multiple sets of drainage buffer components 3 are arranged at equal intervals along the length of the mounting frame 2. Each set of drainage buffer components 3 works independently and together constitutes an array-type diversion buffer system to ensure that the water flow can be effectively dissipated throughout the entire process of flowing through the drainage ditch 1.

[0045] As another preferred embodiment, in order to facilitate the installation and disassembly of the anti-slip component 4 and ensure the tightness of the connection, the circular groove 403 is distributed along the edge of the wire mesh 401, and the screw holes 404 are opened on the mounting crossbeam 2 and correspond one-to-one with the positions of the circular groove 403. The screw 402 passes through the circular groove 403 and is threaded into the screw hole 404. The diameter of the screw nut is designed to be larger than the diameter of the hole in the circular groove 403, so as to effectively press the wire mesh 401.

[0046] As another preferred embodiment, in order to prevent water pressure buildup while blocking solid materials, the wire mesh 401 is constructed as a permeable mesh structure. This mesh structure allows water in the soil to seep out and drain, while intercepting mud, sand and gravel within the mesh, thus achieving the dual functions of physical blocking and drainage pressure relief of the slope.

[0047] The working principle of the drainage and dredging structure for adverse environment slopes of this utility model is as follows:

[0048] When the slope encounters rainfall or surface runoff, the water flows along the slope towards this device, first interacting with the drainage buffer component 3 installed on the crossbeam 2. At this time, if the water flow rate is small, the water mainly flows through the base 303, and the spindle-shaped structure of the base 303 initially diverts the water flow, reducing the concentrated impact force of the water flow on a single point; if the water flow rate is large and the flow velocity is fast, the water flow will first impact the drainage shuttle block 302 located above. The drainage shuttle block 302 uses its spindle-shaped structure with its tip facing the incoming flow to forcibly split the high-speed water flow to both sides, forming a three-dimensional double diversion effect with the base 303 below, greatly reducing the kinetic energy of the water flow.

[0049] After being diverted by the drainage shuttle block 302 and the base 303, the water continues to flow downstream and impacts the buffer block 301. Because the buffer block 301 has a semi-cylindrical structure and an arc-shaped surface facing the water, the water flow is flexibly buffered and guided here, avoiding direct and hard impact on the bottom of the drainage channel 1 that could cause structural damage. Finally, the water flow, having lost its destructive kinetic energy, is smoothly guided into the drainage channel 1 and discharged.

[0050] Meanwhile, the anti-slope component 4 continues to provide protection throughout the process. The wire mesh 401, laid on the surface of the installation frame 2, utilizes its high-strength physical properties to trap solid materials such as mud, sand, and gravel attempting to slide down with the water flow, effectively preventing landslides or collapses. Simultaneously, the mesh structure of the wire mesh 401 allows water to freely permeate and pass through the soil, avoiding excessive pore water pressure within the slope. When it is necessary to clear the trapped mud or replace damaged wire mesh 401, workers can quickly disassemble it by loosening the screws 402 to remove it from the screw holes 404, achieving convenient maintenance of the device.

[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
