Description

Technical Field

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

[0002] The present invention relates to river bank protection structures for water conservancy projects, and in particular to a structural design for river bank stabilization and protection to prevent erosion and landslides while enhancing water flow management in rivers.

[0003] Among the existing river bank protection technologies, commonly used methods include using materials such as stones, concrete blocks or eco-bags to lay on the river bank slopes to reduce the direct scouring of the soil by water. Although these methods can stabilize the river bank and reduce erosion to a certain extent, they have many shortcomings. For example, when encountering a large flow of water, a single material is often unable to withstand the long-term impact of the water flow, and is prone to structural damage or material displacement, thus affecting the overall stability and durability. In addition, these structures usually lack an effective internal drainage mechanism, which causes water to accumulate inside the slope protection structure, increasing the risk of landslides and structural instability.

[0004] Therefore, we proposed a river slope protection structure for water conservancy projects. Utility Model Content

DETAILED DESCRIPTION

[0028] 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.

[0029] See also Figure 1-5 , a river slope protection structure for water conservancy projects,

[0030] It includes a river channel slope protection body 1, on the slope of which slope protection lawns 2 are crisscrossed, a drainage cavity 4 connected to the side of the bottom end of the river channel slope protection body 1 is opened on the inner bottom surface of the river channel slope protection body 1, and the opening of the drainage cavity 4 is connected to the river channel, and a supporting cylindrical mechanism is vertically cast inside the river channel slope protection body 1, and the upper end of each supporting cylindrical mechanism is connected to the inside of a slope protection groove 101 opened on the slope of the river channel slope protection body 1, and the slope protection lawns 2 are laid at the openings of the corresponding slope protection grooves 101, and the bottoms of the supporting cylindrical structures are connected to the inside of the drainage cavity 4, and the height of the supporting cylindrical mechanism gradually shortens as the slope of the river channel slope protection body 1 goes downward.

[0031] Furthermore, the interior of the river slope protection body 1 is filled with a sand and gravel mixture 103, and the sand and gravel mixture 103 wraps the outside of each supporting cylindrical structure.

[0032] Furthermore, the supporting cylindrical structure includes an outer cement column 3 and a drainage pipe 301 on the central axis of the cement column 3 .

[0033] Furthermore, a filter screen plate 401 is installed at the front end opening of the drainage cavity 4. Each of the filter screen plates 401 is made of stainless steel mesh and a corrosion-resistant coating is applied on the surface. The filter screen plate 401 is arranged at the opening of the drainage cavity 4 to filter out impurities in the intercepted river channel and prevent impurities from mixing into the interior of the drainage cavity 4 and clogging the bottom of the corresponding supporting cylindrical mechanism.

[0034] Furthermore, a scratch prevention groove 102 is opened at the lower end of the slope of the river channel slope protection body 1. By opening the scratch prevention groove 102 at the lowest end of the bottom slope of the river channel slope protection body 1, when someone accidentally slides down the slope of the river channel slope protection body 1, the scratch prevention groove 102 can have an interception effect, thereby improving the protection safety.

[0035] Furthermore, the height of the scratch prevention groove 102 is at least ten centimeters.

[0036] How it works

[0037] When in use, in the present technical solution, a sand and gravel mixture 103 is laid inside the channel slope protection body 1, and a supporting cylindrical mechanism is arranged below each slope protection lawn 2 on the inclined surface of the channel slope protection body 1. This can not only guide the excessive aqueous solution on the slope protection groove 101 from the inside of the drain pipe 301 to be discharged into the drainage cavity 4, and then flow into the river along with the drainage cavity 4, but also provide a multi-point support effect for the whole channel slope protection body 1, thereby strengthening the inclined surface support effect of the channel slope protection body 1. At the same time, the supporting cylindrical mechanism in the present technical solution adopts an inner and outer double-layer cement column 3 and a drain pipe 301 to strengthen the supporting effect. At the same time, the aqueous solution flowing into the supporting cylindrical mechanism along with the slope protection groove 101 will not penetrate into the sand and gravel mixture 103, thereby avoiding soil and water loss.

[0038] Main Effects

[0039] Improved slope stability:

[0040] The supporting cylindrical mechanism in the main body of the river channel slope protection provides multi-point support, thereby enhancing the structural stability of the slope protection. This supporting structure can effectively disperse the load of the main body of the river channel slope protection 1 and reduce the risk of slope sliding or collapse caused by lateral pressure.

[0041] Preventing soil erosion: The laying of slope protection lawn 2 not only helps control erosion and maintain soil stability, but also further consolidates the soil through its root system. The lawn is combined with the slope protection groove 101 to form a natural barrier layer to slow down the direct impact of rainwater erosion.

[0042] Drainage efficiency: The design of the internal drain pipe 301 and the drainage chamber 4 allows excess aqueous solution to be efficiently guided and discharged to the river channel, avoiding internal erosion or pressure accumulation caused by excessive accumulation of water, especially under heavy rainfall conditions.

[0043] Filtering function: The filter screen plate 401 (using a stainless steel mesh and a corrosion-resistant coating) at the front end of the drainage cavity 4 can effectively filter and intercept impurities in the river channel, preventing these impurities from entering the drainage system inside the slope protection, thereby reducing maintenance costs and blockage risks.

[0044] Improved protection safety: The lower end of the slope of the river slope protection body 1 is designed with a scratch prevention groove 102. This structure is specially designed to prevent injuries or further erosion when people slide down the slope, thereby improving the personal safety protection of the slope.

[0045] Enhanced durability: The internally filled sand and gravel mixture 103 not only increases the overall quality and stability of the structure, but also reduces the impact of direct water erosion on the cement column by surrounding the supporting cylindrical structure, thereby extending its service life.

[0046] In general, this river bank protection structure effectively combines stability, drainage, filtration and safety functions through its innovative design, adapts to the complex and changeable river environmental conditions, and improves the comprehensive performance and durability of the river bank protection.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
