It also refers to the general term for various paving and planting on the slope. In the rainy season, the water on the upper part of the slope flows in the water. In order to prevent the water from flowing into the river through the slope, the river bank will collapse continuously due to long-term erosion of water flow. Therefore, the slope protection support structure for water conservancy projects has a certain protective effect on the river bank.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] like Figure 1 As shown:

[0023] A slope protection support structure for water conservancy projects comprises a slope protection body 1.

[0024] In this implementation scheme: This application makes further improvements on this existing subject, and for details, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "it is currently inconvenient to drain the rainwater on the slope in a heavy rain environment. When there is too much rain, the impact force of the rainwater will impact the slope protection, thereby causing soil erosion on the slope protection and reducing the shear strength of the soil, which may increase the risk of landslides or collapses and reduce the protection effect of the slope. In addition, rainwater erosion may form grooves, further destroying the use effect of the slope structure reduction device." In terms of use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a drainage protection component 2 is added to the present application document.

[0025] More specifically:

[0026] like Figure 1-Figure 4 As shown:

[0027] A drainage protection assembly 2 is installed on the slope protection body 1, and the drainage protection assembly 2 includes a cavity 213 opened on the top of the slope protection body 1, a water inlet box 201 arranged inside the cavity 213, and multiple groups of tightly fitted filter covers 202 fixedly installed on the upper surface of the water inlet box 201, multiple groups of equidistantly arranged delivery pipes 203 are fixed on the surface of the water inlet box 201, and the slope surface of the slope protection body 1 is paved with sandstone blocks 204;

[0028] The delivery pipe 203 is connected to the water inlet box 201, the delivery pipe 203 is buried inside the sand and gravel block 204, and the filter cover 202 is laid in an inclined structure.

[0029] In this embodiment: the slope protection support structure for water conservancy projects, under heavy rain conditions, rainwater will flow into the water inlet box 201 along the filter cover 202. The filter cover 202 can filter the rainwater to a certain extent. Since the filter cover 202 is designed with an inclined structure, some garbage can fall along the inclined surface of the filter cover 202, which can effectively reduce the accumulation of garbage on the filter cover 202 and affect the clogging situation, further improving the use effect of the device. The rainwater in the water inlet box 201 can be discharged through the delivery pipe 203 and discharged into the river, thereby preventing rainwater from directly scouring the slope protection body 1 and reducing water Soil loss phenomenon, protect the stability of the slope protection body 1, reduce the risk of collapse, and at the same time, the erosion of rainwater on the soil of the slope protection body 1 can be reduced through centralized drainage of rainwater, and the large impact of rainwater can be avoided to form grooves on the slope protection body 1, further improving the use effect of the device. At the same time, the surface of the slope protection body 1 is paved with sand and gravel blocks 204. The paving of the sand and gravel blocks 204 can increase the stability of the slope protection body 1 and prevent landslides caused by rainwater erosion. Due to the good water permeability of the sand and gravel blocks 204, part of the rainwater is directly discharged to the surface of the sand and gravel blocks 204, which can quickly remove the accumulated water to prevent water accumulation and infiltration into the slope protection body 1 to cause collapse.

[0030] In an optional embodiment, a plurality of groups of tightly fitted U-shaped plates 208 are fixed on one side of the upper surface of the slope protection body 1 close to the filter cover 202, a buffer plate 209 is arranged inside the U-shaped plate 208, a rotating rod 211 is fixed at both ends of the buffer plate 209, the other end of the rotating rod 211 is rotatably connected to the U-shaped plate 208 through a bearing, an elastic torsion spring 212 is wound around the surface of the rotating rod 211, a mounting groove 210 is provided on the inner side wall of the U-shaped plate 208 close to the rotating rod 211, and the two ends of the elastic torsion spring 212 are respectively fixedly connected to the U-shaped plate 208 and the buffer plate 209;

[0031] A certain distance is set between the bottom of the buffer plate 209 and the top of the slope protection body 1 .

[0032] In this embodiment, when rainwater on the top of the slope protection body 1 flows into the water inlet box 201 through the gap between the buffer plate 209 and the slope protection body 1, the rainwater will have a greater impact in heavy rain. At this time, the buffer plate 209 is used to block and buffer the rainwater, so as to prevent excessive rainwater from flowing into the water inlet box 201 and passing over the filter cover 202 to the slope protection body 1, thereby improving the support effect of the slope protection body 1. In addition, due to the impact force of rainwater, the buffer plate 209 is impacted at this time. The U-shaped plate 208 is swung at an angle by the rotating rod 211, and the elastic torsion spring 212 is elastically deformed at this time. By setting the elastic torsion spring 212, the maximum flipping angle of the buffer plate 209 relative to the U-shaped plate 208 can be 60°. In this process, the gap between the buffer plate 209 and the slope protection body 1 becomes larger, so that the U-shaped plate 208 can be protected, and the U-shaped plate 208 and the buffer plate 209 are prevented from forming a whole, and the U-shaped plate 208 is prevented from toppling due to the large impact force of water.

[0033] Going further;

[0034] In an optional embodiment, a protective wire mesh 205 is laid on the upper surface of the sandstone block 204 , and fixing pins 214 are provided at the four corners of the protective wire mesh 205 . The fixing pins 214 penetrate the protective wire mesh 205 and are inserted into the interior of the slope protection body 1 .

[0035] In this embodiment: the protective wire mesh 205 is laid on the sand and gravel blocks 204 to cover them. The scattered sand and gravel blocks 204 can be connected through the protective wire mesh 205 to form a whole, thereby improving the overall stability of the slope protection body 1 and preventing landslides or collapses. The fixing pin 214 passes through the protective wire mesh 205 and is inserted into the slope protection body 1 to fix the protective wire mesh 205.

[0036] Going further;

[0037] In an optional embodiment, the upper surface of the protective steel mesh 205 is provided with multiple groups of tightly fitted weighted frame plates 206 , and the lower surface of the weighted frame plates 206 is fixed with multiple groups of plugs 207 , which are inserted into the gaps of the protective steel mesh 205 .

[0038] In this embodiment: the plug 207 on the weighted frame plate 206 is then inserted into the gap of the protective wire mesh 205, which can facilitate the stable laying of the weighted frame plate 206. At the same time, the plug 207 can provide a certain downward pressure, which can protect the stability of the wire mesh and further improve the use effect of the device.

[0039] The working principle and use process of the utility model are as follows: the slope protection support structure used for water conservancy projects, under heavy rain conditions, rainwater will flow into the interior of the water inlet box 201 along the filter cover 202. The setting of the filter cover 202 can produce a certain filtering effect on the rainwater. Since the filter cover 202 is designed with an inclined structure, some garbage can fall along the inclined surface of the filter cover 202, which can effectively reduce the accumulation of garbage on the filter cover 202 and affect the blockage, thereby further improving the use effect of the device. The rainwater in the water inlet box 201 can be discharged through the delivery pipe 203 and discharged into the river, thereby preventing rainwater from directly scouring the slope protection body 1, reducing soil erosion, protecting the stability of the slope protection body 1, and reducing the risk of collapse. The concentrated drainage of rainwater can reduce the erosion of rainwater on the soil of the slope protection body 1, and avoid the formation of grooves on the slope protection body 1 due to the large impact force of rainwater, further improving the use effect of the device. At the same time, the surface of the slope protection body 1 is paved with gravel blocks 204. The paving of the gravel blocks 204 can increase the stability of the slope protection body 1 and prevent landslides caused by rainwater erosion. Since the gravel blocks 204 have good water permeability, part of the rainwater is directly discharged to the surface of the gravel blocks 204, which can quickly remove the accumulated water and prevent water accumulation from penetrating the slope protection body 1 and causing collapse. At the same time, when the rainwater on the top of the slope protection body 1 flows to the inside of the water inlet tank 201 through the gap between the buffer plate 209 and the slope protection body 1, the rainwater will have a greater impact in heavy rain conditions. At this time, the buffer plate 209 is used to block and buffer the rainwater, so as to prevent excessive rainwater from flowing into the water inlet tank 201 in time and passing over the filter cover 202 to be discharged onto the slope protection body 1, thereby improving the support effect of the slope protection body 1. In addition, due to the impact force of rainwater, the buffer plate 209 is impacted at this time, and the buffer plate 209 is swung on the U-shaped plate 208 through the rotating rod 211, and the elastic torsion spring 212 is elastically deformed at this time. Through the setting of the elastic torsion spring 212, the maximum flipping angle of the buffer plate 209 relative to the U-shaped plate 208 can be 60°. In this process, the gap between the buffer plate 209 and the slope protection body 1 becomes larger, so as to protect the U-shaped plate 208 and avoid the U-shaped The plate 208 and the buffer plate 209 form a whole, and the impact force of the water is large, causing the U-shaped plate 208 to topple over. Since the protective wire mesh 205 is laid on the sand and gravel blocks 204 to cover them, the scattered sand and gravel blocks 204 can be connected through the protective wire mesh 205 to form a whole, thereby improving the overall stability of the slope protection body 1 and preventing landslides or collapses. Since the fixing pin 214 passes through the protective wire mesh 205 and is inserted into the slope protection body 1 to fix the protective wire mesh 205, the plug 207 on the weighted frame plate 206 is then inserted into the gap of the protective wire mesh 205, which can facilitate the stable laying of the weighted frame plate 206, and the plug 207 can provide a certain downward pressure.It can protect the stability of the wire mesh and further improve the use effect of the device.
