Description

Technical Field

[0001] The utility model relates to the field of slope management, in particular to a system for irrigating slope vegetation by introducing groundwater from the slope without power. Background Art

[0002] Slope cutting and load reduction is one of the important means of slope management. It can improve the stability of the slope by reducing the load on the slope itself. After slope management, it is usually necessary to drain and prevent seepage on the slope surface after slope cutting to avoid the recurrence of landslides due to excessively high groundwater levels.

[0003] For groundwater in landslide bodies, traditional drainage holes are prone to blockage and it is difficult to reuse groundwater. Utility Model Content

[0004] The main purpose of the utility model is to provide a power-free system for introducing groundwater from a slope to irrigate vegetation on the slope surface, in the hope of effectively solving the problems in the background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A power-free slope groundwater irrigation system for slope vegetation, characterized in that it comprises a siphon, a reservoir, and an irrigation pipe, wherein the siphon comprises a first siphon section and a second siphon section, and the first siphon section is connected to the second siphon section;

[0007] The first siphon pipe section is arranged in an inclined borehole of the slope, and the second siphon pipe section is arranged on the surface of the slope and extends downward;

[0008] The free end of the first siphon section is immersed in the groundwater of the slope; the free end of the second siphon section is at least above the reservoir; the free end of the first siphon section is higher than the free end of the second siphon section; the vertical distance from the free end of the first siphon section to the highest point of the siphon is less than the water column elevation corresponding to the local atmospheric pressure;

[0009] The water reservoir is arranged on the horse trail;

[0010] The irrigation pipe is arranged obliquely on the slope, and the upper end of the irrigation pipe is connected with the bottom of the water reservoir.

[0011] While adopting the above technical solutions, the present invention can also adopt or combine the following technical solutions:

[0012] As a preferred technical solution of the present utility model: the number of the siphon tubes is no more than 600.

[0013] As a preferred technical solution of the utility model: the diameter of a single siphon tube is not greater than 4 mm.

[0014] As a preferred technical solution of the utility model: the siphon tube is a PU tube or a PV tube.

[0015] As a preferred technical solution of the utility model: the irrigation pipe includes a plurality of transverse irrigation pipe sections and a plurality of longitudinal irrigation pipe sections, the longitudinal irrigation pipe sections are arranged obliquely on the slope and the upper ends of the longitudinal irrigation pipe sections are connected to the bottom of the water reservoir; the transverse irrigation pipe sections are staggered and connected with the longitudinal irrigation pipe sections.

[0016] As a preferred technical solution of the utility model: the irrigation pipe is arranged in the soil below the plants on the slope surface.

[0017] As a preferred technical solution of the utility model: the irrigation pipe is a polymer microporous permeable water pipe.

[0018] The utility model provides a power-free slope groundwater irrigation system for slope vegetation, which has the following beneficial effects:

[0019] 1) Improve the landscape effect of slope vegetation. Since the water reservoir arranged on the horse path is used for irrigation below the ground, the green landscape of vegetation will not be blocked, thus bringing a refreshing emotional value to pedestrians and drivers.

[0020] 2) Reduce water resource consumption. This system directly draws groundwater from the inside of the slope to the slope surface for irrigation. There is no need to extract additional water resources from the outside, which can greatly reduce resource consumption and is environmentally friendly. The use of polymer microporous irrigation pipes can improve the utilization rate of irrigation water.

[0021] 3) Reduce the risk of landslide disasters caused by excessively high groundwater levels after slope reduction and load reduction. The power-free water diversion siphon can extract groundwater inside the slope to the reservoir. At the same time, due to the use of specific siphon materials and pipe diameters, the internal bubbles in the water will appear as slug flow under high lift conditions. In this form, the bubbles are discharged with the water under the siphon effect, which will not cause the siphon to be interrupted under long-term use, and has the advantage of long-term operation and maintenance-free.

[0025] The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1-2 As shown, a power-free groundwater irrigation system for slope vegetation includes a siphon 1, a reservoir 3, and an irrigation pipe 4. The siphon 1 includes a first siphon section 101 and a second siphon section 102. The first siphon section 101 is connected to the second siphon section 102.

[0027] The first siphon section 101 is arranged in the inclined borehole 2 of the slope 5, and the second siphon section 102 is arranged on the surface of the slope 5 and extends downward;

[0028] The free end of the first siphon section 101 is submerged in the groundwater of the slope; the free end of the second siphon section 102 is at least above the reservoir 3; the free end of the first siphon section 101 is higher than the free end of the second siphon section 102; the vertical distance from the free end of the first siphon section 101 to the highest point of the siphon 1 is less than the water column height corresponding to the local atmospheric pressure;

[0029] The water reservoir 3 is arranged on the horse trail;

[0030] The irrigation pipe 4 is arranged obliquely on the slope, and the upper end of the irrigation pipe 4 is connected to the bottom of the water reservoir 3.

[0031] The number of the siphon tubes 1 is no more than 600.

[0032] The diameter of a single siphon tube 1 is not greater than 4 mm.

[0033] The siphon tube 1 is a PU tube or a PV tube.

[0034] The irrigation pipe 4 includes a plurality of transverse irrigation pipe sections 401 and a plurality of longitudinal irrigation pipe sections 402. The longitudinal irrigation pipe sections 402 are arranged obliquely on the slope and the upper ends of the longitudinal irrigation pipe sections 402 are connected to the bottom of the reservoir 3. The transverse irrigation pipe sections 401 are staggered and connected with the longitudinal irrigation pipe sections 402.

[0035] The irrigation pipe 4 is arranged in the soil below the plants 6 on the slope.

[0036] The irrigation pipe 4 is a polymer microporous permeable water pipe.

[0037] Specifically, the above-mentioned power-free slope groundwater irrigation system is implemented in the following ways:

[0038] When the system is applied, water is firstly filled into the siphon 1 from the bottom of the second siphon section 102 until the entire siphon 1 is filled with water, and then the free end of the second siphon section 102 is placed in the reservoir 2. Since the top of the first siphon section 101 is connected to the groundwater in the slope, under the action of atmospheric pressure, the groundwater in the slope flows into the reservoir 3 along the siphon 1, and the bottom of the reservoir 3 is connected to the irrigation pipe 4 to irrigate the vegetation 6 on the slope surface. In this process, when the water level in the slope 5 drops below the top of the first siphon section 101, the siphon is suspended; when the water level in the slope 5 returns to above the top of the first siphon section 101, the siphon is restored. Under the conditions of the material and diameter of the siphon 1, the gas in the pipe exists in the form of slug flow, and when the siphon is restored, it is discharged from the siphon along with the groundwater.

[0039] The above-mentioned specific implementation methods are used to explain the present invention and are only preferred embodiments of the present invention, rather than limiting the present invention. Any modifications, equivalent substitutions, improvements, etc. made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
