Description

Technical Field

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

[0002] In water conservancy projects, in order to meet the requirements of anti-seepage and anti-scour, etc., it is often necessary to build revetments on both sides of the riverbank for protection. The common revetment method is direct protection, directly strengthening the riverbank slope to resist the scouring and erosion of water flow, and it is commonly built with riprap, dry-laid rubble masonry, grouted rubble masonry, stone cages and fascines, etc. The slope protection structure is also used to protect the road surface in some sections with higher road surfaces or on both sides of highways.

[0003] The existing slope protection design in water conservancy projects has defects. For example, a revetment bearing structure is set on both sides of the river channel, a waist beam is poured closely against the revetment bearing structure at the bottom of the river channel, several groups of concrete support beams are arranged between the waist beams on both sides of the river channel, vertical concrete support walls are poured between the two ends of each group of support beams and the waist beam, the lower end of the concrete support wall penetrates into the bottom of the river channel and the upper end is higher than the waist beam, and concrete piles and concrete retaining walls are lined between the higher part of the concrete support wall and the revetment bearing structure on the same side. Most of such designs have insufficient stability. A single concrete wall or riprap, rubble masonry, etc. may be displaced under the long-term scouring of floods, easily causing the collapse or even collapse of the slope protection, and there are certain safety hazards.

[0044] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0045] Please refer to Figures 1 to 3 , the slope protection provided by the embodiment of the present utility model includes a slope body and a buffer frame 6; the slope body includes a base layer 1, a first gravel layer 2, a concrete layer 3, a second gravel layer 4, and a cement board layer 5 that are sequentially laid upward along the vertical direction; the cement board layer 5 has an installation surface and an inclined surface arranged oppositely, and the inclined surface gradually inclines away from the installation surface from the top to the bottom of the slope body along the vertical direction; the buffer frame 6 is installed on the inclined surface.

[0046] Specifically, the base layer 1 is laid on the bottommost layer, and then the first gravel layer 2, the concrete layer 3, the second gravel layer 4, and the cement board layer 5 are sequentially laid upward. The slope body after laying is trapezoidal, the top surface is horizontal, and the inclined surface slopes gently from high to low; the buffer frame 6 is installed on the inclined surface.

[0047] This slope protection can be applied to water conservancy projects, sections of roads with a relatively high road surface, or both sides of highways; the installation surface of the cement board layer 5 is fixedly connected to the river bank or the roadbed, and the inclined surface of the cement board layer 5 is the slope surface. The slope body forms a multi-layer structure through the first gravel layer 2, the concrete layer 3, the second gravel layer 4, the cement board layer 5, and the buffer frame 6, and the multi-layer structure improves the stability of this slope protection; through the concrete layer 3 located between the first gravel layer 2 and the second gravel layer 4, the first gravel layer 2 and the second gravel layer 4 can be well fixed, making the slope body form a whole, thereby making the slope body have higher strength. The slope body can further wrap the second gravel layer 4 through the cement board layer 5, making the gravel inside the second gravel layer 4 not easy to disperse, more compact, and improving the stability of the slope body. The buffer frame 6 is installed on the inclined surface of the cement board layer 5, and during the scouring of floods, it protects the slope body from being damaged by the scouring of floods and is safer to use.

[0048] In an alternative solution of the embodiment of the present utility model, the buffer frame 6 is in plug-in fit with the inclined surface.

[0049] Specifically, refer to Figure 2, the bottom of the buffer rack 6 is inserted into the inclined surface of the cement board layer 5. After insertion, the top of the buffer rack 6 protrudes from the cement board layer 5, and the buffer rack 6 is fixed on the inclined surface of the cement board layer 5.

[0050] The buffer rack 6 is inserted on the cement board layer 5, which plays a buffering role during flood scouring, avoiding the entire slope from being further damaged and collapsed after the cement board layer 5 is impacted and pitted under the scouring of a large amount of water.

[0051] In an alternative embodiment of the present utility model, the inclined surface is provided with a plurality of slots 8, and the buffer rack 6 is provided with a plurality of insertion blocks 7. The plurality of insertion blocks 7 are arranged at intervals on the bottom surface of the buffer rack 6; the plurality of slots 8 are in one-to-one correspondence and insertion fit with the plurality of insertion blocks 7.

[0052] Specifically, in this embodiment, four insertion blocks 7 are provided at the bottom of the buffer rack 6, and four slots 8 are provided at the corresponding positions of the inclined surface. The insertion blocks 7 are all inserted into the slots 8 for fixation. The buffer rack 6 is of a hollow design, presenting an overall "day" shape, and the four insertion blocks 7 at the bottom of the buffer rack 6 are arranged at the four corners of the "day" shape.

[0053] The design of the plurality of insertion blocks 7 and the plurality of slots 8 realizes the fixation and limitation of the buffer rack 6. When floods or heavy rains occur, the buffer rack 6 is not easily displaced or detached under the scouring of floods and heavy rains, enhancing the safety of use.

[0054] In an alternative embodiment of the present utility model, a plurality of buffer racks 6 are provided, and the plurality of buffer racks 6 are arranged at intervals along the inclined direction and / or the extending direction of the inclined surface.

[0055] Specifically, the inclined direction of the inclined surface in the above text refers to the direction from the top to the bottom of the inclined surface; the extending direction of the inclined surface refers to the length direction of the inclined surface. In this embodiment, several buffer racks 6 form a column, and a certain distance is spaced between each buffer rack 6 for spaced arrangement. Each column of buffer racks 6 is spacedly arranged on the inclined surface of the cement board layer 5 and extends along the horizontal direction of the slope protection. Of course, only one column of buffer racks 6 is provided on the inclined surface of the cement board layer 5 or only one buffer rack 6 is provided in each column on the inclined surface of the cement board layer 5 should also be within the protection scope of the present utility model, and the specific setting can be adjusted according to the on-site installation requirements.

[0056] When floods or heavy rains occur, the setting of the plurality of buffer racks 6 can effectively retain floods or heavy rains, avoid floods or heavy rains from repeatedly scouring the slope protection, and play a role in protecting the slope protection.

[0057] In an alternative solution of the embodiment of the present utility model, the first gravel layer 2 is located in the middle of the base layer 1, the concrete layer 3 covers the first gravel layer 2 and the bottom wall of the concrete layer 3 is attached to the base layer 1; the second gravel layer 4 covers the concrete layer 3 and the bottom wall of the second gravel layer 4 is attached to the base layer 1; the cement board layer 5 covers the second gravel layer 4 and the bottom wall of the cement board layer 5 is attached to the base layer 1.

[0058] Specifically, during laying, the first gravel layer 2 is laid in the middle of the base layer 1. When the concrete layer 3 and the second gravel layer 4 are laid in sequence, they completely cover the upper layer, and the bottom edge of each layer is fixed after contacting the upper surface of the base layer 1. When the last cement board layer 5 is laid, it covers all other layers including the upper surface of the base layer 1, and the edge of the cement board layer 5 is in the same vertical plane as the edge of the base layer 1.

[0059] The first gravel layer 2 is laid in the middle of the base layer 1, and the edge of the concrete layer 3 covering it contacts the base layer 1, completely wrapping the entire first gravel layer 2, which can effectively prevent the first gravel layer 2 from spreading or falling off. The second gravel layer 4 laid on the concrete layer 3 is also fixed by the concrete layer 3. The cement board layer 5 laid on the second gravel layer 4 completely wraps other layers including the upper surface of the base layer 1, so that only the cement board layer 5 and the base layer 1 of the entire slope protection are exposed, further improving the overall strength of the slope protection.

[0060] In an alternative solution of the embodiment of the present utility model, the slope protection further includes a protection board 10. A water collecting groove 9 is provided at the top of the cement board layer 5, and the water collecting groove 9 extends along the extension direction of the slope; an installation groove 11 is provided on the side wall of the water collecting groove 9, and the protection board 10 is detachably installed in the installation groove 11.

[0061] Specifically, installation grooves 11 are provided on two opposite side walls of the water collecting groove 9. The position of the installation grooves 11 is at the upper edge of the side wall, and the opening direction of the installation grooves 11 extends along the extension direction of the water collecting groove 9. In this embodiment, the protection board 10 is designed in a rectangular shape and has a grid board structure. The side edges of the protection board 10 are installed in the installation grooves 11 by an embedding method, and multiple protection boards 10 can completely cover the water collecting groove 9. Of course, protection boards 10 with other shapes and structures that can cover the water collecting groove 9 should also be within the protection scope of the present utility model.

[0062] The design of the water collecting groove 9 can drain the accumulated water on the embankment or the road surface into the water collecting groove 9, reducing the accumulated water on the road surface. After the protection board 10 covers the water collecting groove 9, it can prevent some sundries on the roadside or in the air from falling into the water collecting groove 9, reducing the possibility of the water collecting groove 9 being blocked. At the same time, the protection board 10 can also prevent pedestrians, vehicles, etc. on the roadside or the embankment from falling into the water collecting groove 9, increasing safety.

[0063] In an optional solution of the embodiment of the utility model, the bottom wall of the water collecting trough 9 is provided with a plurality of drainage holes 12 ; the plurality of drainage holes 12 are arranged along the extension direction of the water collecting trough 9 .

[0064] Specifically, in this embodiment, the drainage holes 12 are arranged at intervals on the bottom wall of the water collecting trough 9, and are arranged at one end of the water collecting trough 9 close to the inclined surface. The closer the bottom wall of the drainage trough is to the inclined surface, the lower the height is.

[0065] When a rainstorm occurs, the water collection tank 9 will be flooded quickly due to excessive water. The addition of the drainage holes 12 can effectively drain the excess water in the water collection tank 9. After the water on the road flows into the water collection tank 9, it will naturally fall into the drainage holes 12 under the action of gravity, thereby protecting the road surface and the slope.

[0066] In an optional solution of the embodiment of the utility model, the slope protection also includes a drainage channel 13; the drainage channel 13 is located at the bottom of the slope and is fixedly connected to the base layer 1; the side wall where the drainage channel 13 is connected to the base layer 1 is provided with a drainage hole 14 connected to the drainage hole 12.

[0067] Specifically, the drainage channel 13 is installed at the intersection of the bottom of the slope and the base layer 1. One side of the drainage channel 13 is fixedly connected to the base layer 1, the top of the drainage channel 13 is at the same height as the bottom of the slope, and the other side of the drainage channel 13 is at the same height. A drainage hole 14 is opened on the side wall of the drainage channel 13 connected to the base layer 1, and the cross section of the drainage hole 14 is perpendicular to the bottom wall of the drainage channel 13. The drainage holes 14 are arranged at intervals on the second side wall of the drainage channel 13, and the number of the drainage holes 14 corresponds to the drainage holes 12 one by one.

[0068] By setting up the drainage channel 13, the accumulated water can be guided to the required location, so as to buffer and guide a large amount of precipitation or flood in a short period of time; at the same time, by setting up the drainage holes 12 and the drainage holes 14, the function of discharging the accumulated water on the road surface can be further enhanced, the traffic safety hazards caused by the accumulated water can be eliminated, and the safety of pedestrians and vehicles on the road surface can be guaranteed.

[0069] In the optional scheme of the embodiment of the utility model, see Figure 3 A drainage pipe 15 is provided inside the slope; one end of the drainage pipe 15 is connected to the drainage hole 12, and the other end of the drainage pipe 15 is connected to the drainage hole 14.

[0070] Specifically, in this embodiment, the drainage hole 12 and the drainage hole 14 are connected by drilling, and a drainage pipe 15 is installed between each drainage hole 12 and its corresponding drainage hole 14. The drainage pipe 15 can be a metal pipe or a plastic pipe, without limitation. The path of the drainage pipe 15 is preferably directly connected to the drainage hole 12 and the drainage hole 14 along a straight line.

[0071] Through the connection function of the drain pipe 15, the water in the water collecting tank 9 can quickly flow into the drain hole 14 through the drain hole 12, and then flow into the drainage channel 13 and be discharged, further accelerating the drainage speed of the water accumulation on the road surface. The pipeline arranged between the drain hole 12 and the drain hole 14 can also reduce the soaking of the water accumulation on the first gravel layer 2, the second gravel layer 4 and the concrete layer 3 in the slope body, and extend the service life of the slope body.

[0072] In an alternative embodiment of the present utility model, a ladder 16 is embedded on the inclined surface of the cement board layer 5, and the ladder 16 is arranged along the inclined direction of the inclined surface; the ladder 16 and the buffer frame 6 are arranged at intervals along the extending direction of the inclined surface.

[0073] Specifically, the ladder 16 is installed on the inclined surface, with the upper edge connected to or close to the top end of the inclined surface, and the lower edge connected to or close to the bottom end of the inclined surface. In this embodiment, multiple ladders 16 can be provided, and the multiple ladders 16 are embedded at intervals on the inclined surface of the slope body, and several rows of buffer frames 6 can be arranged at intervals between the ladders 16. Preferably, the ladder 16 can also be arranged by directly excavating on the cement board layer 5. Preferably, a guardrail can also be arranged beside the drainage channel 13 to protect the drainage channel 13 and the drain hole 14, and prevent small animals, humans, etc. from accidentally falling into the drainage channel 13.

[0074] After the ladder 16 is arranged on the slope body, maintenance personnel can directly use the ladder 16 to go from the top of the slope to the bottom of the slope to repair facilities such as the drainage channel 13 and the drain hole 14; they can also replace and repair the buffer frames 6 arranged at intervals beside the ladder 16, etc., improving the maintenance convenience of the slope protection.
