Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy slopes, in particular to a slope protection structure used in water conservancy projects. Background Art

[0002] Slope protection structures in water conservancy projects are crucial for ensuring the safety and long-term stability of the project. Their primary function is to prevent slope landslides, soil erosion, and water scour, thereby protecting the project infrastructure and extending its service life. In terms of preventing landslides, the slope protection structure can enhance the stability of the slope and reduce the risk of landslides and soil erosion; in terms of water flow guidance, it can effectively reduce the direct impact of water flow on the slope and avoid soil erosion. At the same time, through reasonable design, the slope protection structure can also improve the bearing capacity of the slope and prevent the slope from being damaged by excessive loads; as disclosed in the authorization announcement number CN217399530U, a slope protection structure for water conservancy projects comprises a slope body, the top of the slope body is fixedly installed with a top slope, the bottom of the slope body is fixedly installed with a bottom slope, the top of the top slope is movably installed with a sliding cover, the top of the sliding cover is fixedly installed with a filter screen, the front of the slope body is fixedly installed with a drainage pipe, the front of the bottom slope is provided with a drainage hole, and the front and back of the top slope are provided with chutes. By setting the drainage pipe, the water entering the slope protection can be drained in time to avoid the occurrence of landslides caused by water accumulation inside the slope protection. The drainage ditch is protected to prevent debris from clogging the drainage ditch, and the sliding cover can be opened at any time to facilitate staff to clean the inside of the drainage ditch. However, during the use of the above technical solution, the drainage pipes used for water diversion are evenly spaced on the slope surface of the slope protection, that is, the design of the drainage pipes is based on a certain precipitation amount and water flow rate. However, the actual precipitation is often more severe than the design expectations, especially in extreme weather such as heavy rain. The capacity of the drainage pipes may not be able to meet the discharge needs of large-flow rainwater. If the diameter of the drainage pipes is too small or the number is insufficient, the flow of the drainage system cannot match the speed and magnitude of the downward flow of water, resulting in water accumulation on the surface of the slope protection, and even infiltration through the soil, forming waterlogging. At this time, the water flow directly impacts the soil, increasing the loss of surface soil and further damaging the slope structure. Especially when the surface cover of the slope protection is weak and the plants fail to form an effective root structure, the soil loss problem is more serious. Utility Model Content

[0003] The purpose of the utility model is to provide a slope protection structure for water conservancy projects, which is composed of a left L-shaped frame side, a right L-shaped frame side, a T-shaped middle frame and a plurality of herringbone longitudinal beams connected to the frame sides. When rainwater on the slope protection surface flows down the slope surface, the plurality of herringbone longitudinal beams block the rainwater and soil layer by layer, and the rainwater flows out through the notch, while the soil is blocked and retained by the herringbone longitudinal beams. At the same time, a gap for vegetation growth is provided between two adjacent herringbone longitudinal beams, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a slope protection structure for a water conservancy project, comprising a left L-shaped frame side and a right L-shaped frame side arranged on one side of the left L-shaped frame side, a T-shaped middle frame is arranged between the left L-shaped frame side and the right L-shaped frame side, a plurality of herringbone longitudinal beams are welded to the outer walls of both sides of the T-shaped middle frame, the end of the herringbone longitudinal beam away from the T-shaped middle frame is welded to the outer wall of the left L-shaped frame side or the right L-shaped frame side, a plurality of equally spaced notches are opened on the outer walls of both sides of the herringbone longitudinal beam, and a gap is provided between two adjacent herringbone longitudinal beams.

[0005] Preferably, the bottom ends of the left L-shaped frame side and the right L-shaped frame side are both provided with a plurality of positioning holes.

[0006] Preferably, the left L-shaped frame side, the right L-shaped frame side, the T-shaped middle frame, and the herringbone longitudinal beam are all made of alloy steel.

[0007] Preferably, a convex edge is fixed on the outer wall of the left L-shaped frame side away from the T-shaped middle frame, and limiting holes that completely pass through the surface of the convex edge are provided at both ends.

[0008] Preferably, a C-shaped frame is fixed on the outer wall of the right L-shaped frame away from the T-shaped middle frame, and a spring positioning pin is installed on the top of the C-shaped frame. After the convex edge and the C-shaped frame are plugged in, the pin end of the spring positioning pin and the limiting hole are plugged into each other.

[0009] Preferably, the cross section of the notch is circular.

[0010] Compared with the prior art, the beneficial effect of the present invention is as follows: the slope protection structure for water conservancy projects is composed of a left L-shaped frame edge, a right L-shaped frame edge, a T-shaped middle frame, and a plurality of herringbone longitudinal beams connected to the frame edges, and by providing a gap between adjacent longitudinal beams for vegetation growth, the purpose of water diversion, soil blocking and reinforcement, and plant soil consolidation is achieved. Each level of herringbone longitudinal beams forms a water cutoff layer, which can effectively slow down the speed of water flow, thereby reducing the direct scouring effect of water flow on the slope soil. The slower the water flow, the smaller the water scouring force and the weaker the erosion effect on the soil. This layered blocking method avoids large-scale water flow impact and reduces the loss of slope soil. The roots of plants can penetrate deep into the soil, fix the soil layer, reduce soil loss, and reduce soil evaporation through plant transpiration. The moisture in the soil can be reduced, the humidity fluctuation of the soil can be alleviated, thereby increasing the stability of the soil. In particular, for some water-loving plants or native plants, they can grow rapidly in the gaps, forming a cover layer, further enhancing the slope protection effect.

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-5The utility model provides an embodiment: a slope protection structure for a water conservancy project, comprising a left L-shaped frame side 1 and a right L-shaped frame side 2 arranged on one side of the left L-shaped frame side 1, a T-shaped middle frame 3 is arranged between the left L-shaped frame side 1 and the right L-shaped frame side 2, a plurality of herringbone longitudinal beams 4 are welded to the outer walls of both sides of the T-shaped middle frame 3, an end of the herringbone longitudinal beam 4 away from the T-shaped middle frame 3 is welded to the outer wall of the left L-shaped frame side 1 or the right L-shaped frame side 2, a plurality of notches 401 with equal spacing are opened on the outer walls of both sides of the herringbone longitudinal beam 4, and a gap 5 is provided between two adjacent herringbone longitudinal beams 4;

[0019] The bottom ends of the left L-shaped frame side 1 and the right L-shaped frame side 2 are both provided with a plurality of positioning holes 101. The left L-shaped frame side 1, the right L-shaped frame side 2, the T-shaped middle frame 3, and the herringbone longitudinal beam 4 are all made of alloy steel.

[0020] The herringbone longitudinal beams 4 need to be precisely arranged according to the design requirements to ensure that the width of the gaps 5 between the herringbone longitudinal beams 4 is suitable for the growth of vegetation. During installation, the welding strength of the longitudinal beams must be ensured so that they can withstand the impact of water flow during heavy rain.

[0021] The cross section of the notch 401 is formed to be circular. When rainwater flows down the slope, it will first be blocked by the layers of herringbone longitudinal beams 4. The herringbone longitudinal beams 4 can effectively slow down the speed of the water flow and prevent the water flow from directly eroding the slope soil. At the same time, the notch 401 on the outer wall of the herringbone longitudinal beam 4 allows the water to flow out of the frame area smoothly, avoiding water accumulation on the slope and reducing waterlogging.

[0022] A convex edge 6 is fixed to the outer wall of the left L-shaped frame side 1 on the side away from the T-shaped middle frame 3, and limiting holes 601 are set at both ends of the surface of the convex edge 6 and extend completely through it. A C-shaped frame 7 is fixed to the outer wall of the right L-shaped frame side 2 on the side away from the T-shaped middle frame 3, and a spring positioning pin 8 is installed on the top of the C-shaped frame 7. After the convex edge 6 and the C-shaped frame 7 are plugged into each other, the pin end of the spring positioning pin 8 and the limiting hole 601 are plugged into each other;

[0023] When the slope protection structure is arranged along the extension direction of the slope protection, the convex edge 6 is plugged into the C-shaped frame 7 to connect the left L-shaped frame side 1 and the right L-shaped frame side 2. At this time, the pin end of the spring positioning pin 8 is automatically pushed into the limiting hole 601, and the spring positioning pin 8 and the limiting hole 601 are used to lock the C-shaped frame 7 and the convex edge 6, so that the two adjacent slope protection structures are connected. Through multi-level physical barriers, ecological protection and water flow guidance functions, the problems of rainwater erosion, soil loss and slope sliding are effectively solved.

[0024] When the embodiment of the present application is in use, the staff first fixes the slope protection frame composed of the left L-shaped frame side 1, the right L-shaped frame side 2, and the T-shaped middle frame 3 on the slope surface of the water conservancy slope through ground bolts. The design of the L-shaped and T-shaped frames makes the entire frame structure have good bearing capacity, which can effectively disperse the impact force of rainwater and avoid excessive water flow directly acting on the slope surface. When there is rainwater on the slope surface, the shape design of the herringbone longitudinal beam 4 can make the rainwater evenly distributed on the longitudinal beam, slow down the flow rate of rainwater, and reduce the direct scouring force of water flow on the soil. In addition, the notch 401 on the outer wall of the herringbone longitudinal beam 4 allows the water flow to flow away directly. It avoids soil erosion caused by water gathering on the slope surface, and because the herringbone longitudinal beams 4 are arranged step by step along the slope surface, they can effectively retain the soil on the slope surface and prevent it from being lost with rainwater, which helps to maintain the stability of the slope soil and reduce the risk of landslide or collapse. The gaps 5 formed between adjacent herringbone longitudinal beams 4 provide space for growing vegetation. The roots of vegetation in the gaps 5 can effectively fix the soil and reduce the impact of water on the soil, so as to improve the problem of soil and water loss and further enhance the anti-scouring ability of the slope surface. As the vegetation grows, the gaps will gradually form a covering layer to enhance the natural protection ability of the slope.
