Description

Technical Field

[0001] The invention relates to the field of ecological wall drip irrigation systems, and in particular to a non-powered drip irrigation system based on an assembled retaining wall. Background Art

[0002] In the engineering field, high slopes that need to be supported are often encountered. Pile-slab retaining wall support is often used in construction, highway, municipal engineering, etc. It has a wide range of applications and good effects in reinforcing and supporting slopes. Commonly used ecological retaining walls are cast-in-place reinforced concrete slabs, which are used to support the soil between piles.

[0003] At present, the existing ecological retaining walls that have been widely used have a long construction period for their support methods, and the living environment of surface plants is poor. Manual watering is often required to ensure that the soil inside the ecological retaining wall is moist and suitable for plant survival. Manual watering using equipment often cannot be sustained for many days. Often in dry weather, if there is no water for irrigation, the soil inside the ecological retaining wall will dry out and crack, causing the plants inside to dry up. Frequent use of equipment for irrigation will consume a lot of manpower and material resources. Summary of the invention

[0004] The technical problem to be solved by the present invention is that artificial irrigation of ecological retaining walls is often not possible for a long time, so that in dry weather, the soil inside the ecological retaining walls dries up and the plants wither. The purpose is to provide a non-powered drip irrigation system based on an assembled retaining wall, which can continuously irrigate the ecological retaining wall and keep the soil inside the ecological retaining wall moist.

[0005] The present invention is achieved through the following technical solutions:

[0006] A non-powered drip irrigation system based on an assembled retaining wall, comprising:

[0007] A retaining wall module, the retaining wall module comprising a supporting wall, a planting bottom plate and an extended outer plate, a through hole is opened at the center of the planting bottom plate, and a soil layer is arranged on the planting bottom plate;

[0008] A drip irrigation assembly, wherein the drip irrigation assembly penetrates the through hole and is arranged in the retaining wall module;

[0009] A water reservoir, wherein the water outlet of the water reservoir is connected to the upper end of the drip irrigation assembly;

[0010] Among them, the tops and bottoms of several of the retaining wall modules are spliced ​​together to form an ecological retaining wall, the water reservoir is arranged at the top of the ecological retaining wall, the water in the water reservoir enters the drip irrigation component through the water outlet of the water reservoir, and is drip-irrigated into the retaining wall module through the drip irrigation component.

[0011] Preferably, the water stored in the water reservoir will be drip-irrigated through the drip irrigation assembly, and a soil layer is provided in the retaining wall module, in which green plants can be planted. After the drip irrigation assembly is filled with water, the water reservoir will continue to inject water into the drip irrigation assembly, and the drip irrigation assembly will overflow to the outside, and the overflowed water will continue to drip into the soil layer, so that the soil layer in the retaining wall module remains moist, avoiding the soil from drying out and cracking in dry weather, which affects the growth of plants in the soil layer. In the prior art, the ecological retaining wall is often irrigated at regular intervals by manual labor and equipment. The ecological retaining wall is generally set up in areas such as high-altitude highways and is often not accessible frequently. Therefore, in dry weather, the soil in the ecological retaining wall cannot be irrigated in time, which will cause the green plants to dry up. The drip irrigation assembly and water reservoir in this solution can irrigate the soil layer for a long time. After the water reservoir is filled with water for the first time, the water flows along the drip irrigation assembly to the soil layer in each retaining wall module.

[0012] In view of the above problems, a non-powered drip irrigation system based on an assembled retaining wall is provided. A water valve can be set at the water outlet of the water reservoir or the drip irrigation component to adjust the water flow so that the water overflowing from the drip irrigation component is of drip irrigation type, and the overflowing water flow is controlled in a stable state, which can not only reduce unnecessary loss of water sources, but also keep the soil moist at all times. In rainy weather, the water reservoir on the top of the ecological retaining wall will prevent rainwater from eroding the soil layer, and the water reservoir can collect rainwater. There is a gap between the laterally adjacent retaining wall modules, and the rainwater can be discharged into the gap. The extended outer plate is inclined at the top surface of the retaining wall module. In heavy rain weather, rainwater falls into the retaining wall module, is blocked by the soil layer and exists on the extended outer plate, and the rainwater will flow to both sides along the inclined extended outer plate and fall on the ground, which will not cause water accumulation in the retaining wall module and affect the soil layer.

[0013] In some optional technical solutions, a groove is provided on the bottom surface of the supporting wall, a protrusion is provided on the top surface of the supporting wall for engaging with the groove, the extended outer panel has an arc-shaped structure, and the height of the extended outer panel gradually decreases from the center toward the two sides of the extended outer panel.

[0014] Preferably, the retaining wall modules can be assembled by interlocking protrusions and grooves to form an ecological retaining wall. The assembled ecological retaining wall is convenient for assembly and disassembly. In heavy rain, the arc-shaped extended outer plate can direct rainwater to flow to both sides along the extended outer plate, and it is not easy to store rainwater on the surface of the soil layer, causing soil loss.

[0015] In some optional technical solutions, the drip irrigation assembly includes a plurality of branch pipes and a main pipe, the branch pipes are connected to the main pipe via pipe joints, and the branch pipes are arranged on both sides of the main pipe.

[0016] Preferably, the drip irrigation assembly is composed of several branch pipes and several main pipes connected to each other through pipe joints. The main pipe on the top layer is connected to the water reservoir. The main pipe guides the water in the water reservoir into the branch pipe. Branch pipes are arranged on both sides of the main pipe to fully moisten the soil layer.

[0017] In some optional technical solutions, the water storage pipe is of a U-shaped structure, the water storage pipe is arranged in the soil layer, the top of the water storage pipe is at a distance from the soil layer, a drip irrigation pool is arranged at the top of the water outlet of the water storage pipe, a water inlet hole connected to the inner cavity of the water storage pipe is provided on the bottom surface of the drip irrigation pool, a plurality of drip holes are provided on the outer wall of the drip irrigation pool, the diameter of the drip hole is 0.4 mm, and the water storage pipe is made of corrosion-resistant metal.

[0018] Preferably, when water flows in the branch pipe, the water will flow into the water storage pipe. According to the principle of communicating vessels, after the water enters the water storage pipe, it will continue to enter the drip irrigation tank along the water diversion hole. The water in the drip irrigation tank can overflow from the drip hole to gradually moisten the soil layer. The U-shaped structure allows the water storage pipe to still store part of the water when the water source is missing. When the water in the water storage tank dries up, the metal water storage pipe buried in the soil layer can keep the surrounding soil moist, thereby preventing the soil layer from drying up completely and causing the vegetation to wither.

[0019] A float valve is arranged at the water inlet, and the liquid level height when the float valve is closed is higher than the height of the drip hole.

[0020] Preferably, the float valve can be used to automatically draw water from the water storage pipe through the water diversion hole when there is a lack of water in the drip irrigation pool. When the water in the drip irrigation pool reaches the liquid level set by the float valve, the float valve closes, and the water source can no longer continue to supply water to the drip irrigation pool through the water diversion hole. The water in the drip irrigation pool can overflow through the drip hole to drip irrigate the soil layer, and the drip irrigation speed of each layer of the ecological retaining wall is the same.

[0021] A water-absorbing cotton rope is arranged in the water storage pipe. The water-absorbing cotton rope passes through the inner cavity of the water storage pipe, penetrates the water diversion channel of the float valve, passes through the drip irrigation pool and is buried in the soil layer.

[0022] Preferably, when the water source in the water reservoir is exhausted, the drip irrigation assembly can no longer supply water, but water is stored in the U-shaped water storage pipe. At this time, the float valve is in an open and closed state, and the internal absorbent cotton rope can introduce the water in the water storage pipe into the soil layer to keep the soil layer moist.

[0023] In some optional technical solutions, a water pump is provided on one side of the retaining wall module, an output port of the water pump is connected to a water diversion pipe, and the other end of the water diversion pipe is located directly above the water reservoir.

[0024] Preferably, after the retaining wall module is assembled, water can be pumped into the reservoir through a water pump to operate the drip irrigation assembly. In addition, in dry weather when the water source in the water pipe is exhausted, water can also be pumped into the reservoir through a water pump.

[0025] In some optional technical solutions, a cover plate is provided on the top of the water reservoir, and a through groove is opened in the center of the cover plate.

[0026] Preferably, the cover plate can block some garbage from entering the water reservoir, and the cover plate can reduce the evaporation rate in the water reservoir.

[0027] In some optional technical solutions, the top surface of the cover plate is recessed downward toward the center of the cover plate, and the side of the cover plate facing the water reservoir is covered with a waterproof tape.

[0028] Preferably, on rainy days or when the water pump is filling, the water source falling on the top layer of the cover plate can slide to the center of the cover plate and enter the water reservoir through the through groove. The waterproof tape on the bottom layer of the cover plate can make the evaporated water in the water reservoir form water droplets attached to the waterproof tape, and continue to fall into the water reservoir for reuse over time.

[0029] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0030] 1. The ecological retaining wall can be assembled through several retaining wall modules to improve work efficiency. The water in the reservoir on the top layer of the ecological retaining wall can be circulated through the drip irrigation component. According to the principle of the connecting vessel, the soil layer of each layer can be drip irrigated. No other power equipment is required to operate this system;

[0031] 2. The float valve in the drip irrigation pool can attract water from the water storage pipe. When the liquid level in the drip irrigation pool reaches the set value, the float valve closes and stops diverting water. At this time, the drip irrigation pools on each layer of the ecological retaining wall can drip irrigation to the soil layer along the drip holes at the same speed to keep the soil layer moist;

[0032] 3. The water storage pipe is a U-shaped structure. When the water source in the water storage tank and the drip irrigation assembly dries up, the water storage pipe can still store some water in the lumen. The absorbent cotton rope can infiltrate the soil layer through the water source in the water storage pipe, so that the soil layer can still be kept moist in dry weather and is not easy to crack;

[0033] 4. The bottom surface of the cover is provided with waterproof tape, which can reduce the evaporation rate of water in the reservoir. The top surface of the cover is concave downward toward the center of the cover, which is convenient for collecting rainwater when water is injected through the water injection pump or in rainy weather.

[0046] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. The schematic implementation modes and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0047] like Figures 1 to 3 As shown, this embodiment provides a non-powered drip irrigation system based on a prefabricated retaining wall, comprising:

[0048] The retaining wall module 1 includes a supporting wall 11, a planting bottom plate 12 and an extended outer plate 13. A through hole is opened at the center of the planting bottom plate 12, and a soil layer is arranged on the planting bottom plate 12;

[0049] A drip irrigation assembly, wherein the drip irrigation assembly is provided with a through hole in the retaining wall module 1;

[0050] A water reservoir 2, wherein the water outlet of the water reservoir 2 is connected to the upper end of the drip irrigation assembly;

[0051] Among them, the tops and bottoms of several retaining wall modules 1 are spliced ​​together to form an ecological retaining wall. The water reservoir 2 is arranged at the top of the ecological retaining wall. The water in the water reservoir 2 enters the drip irrigation component through the water outlet of the water reservoir 2, and is drip-irrigated into the retaining wall module 1 through the drip irrigation component.

[0052] like Figure 1 and Figure 2 As shown, a groove is provided on the bottom surface of the supporting wall 11, and a protrusion for engaging with the groove is provided on the top surface of the supporting wall 11. The extended outer plate 13 is an arc-shaped structure, and the height of the extended outer plate 13 gradually decreases from the center toward the two sides of the extended outer plate 13.

[0053] A hanging hole is provided on one side of the supporting wall 11 close to the planting base plate 12. The opening shape of the hanging hole is elliptical. There are two hanging holes and they are mirror-distributed with the axis of symmetry of the retaining wall module 1. A through hole for the drip irrigation system is provided in the center of the planting base plate 12. The top surface of the soil layer is an inclined surface. The soil layer gradually increases from the extended outer plate 13 to the planting base plate 12. The extended outer plate 13 is an arc-shaped structure.

[0054] Specifically, the retaining wall modules 1 can be assembled with each other to form an ecological retaining wall. When assembling the ecological retaining wall, the hook of the crane can be used to hook the lifting hole on the supporting wall 11 to move the retaining wall module 1 to the specified position. After the retaining wall module 1 of the bottom layer is placed, the remaining retaining wall modules 1 are stacked in sequence on top of the retaining wall module 1 of the bottom layer by the crane, and the grooves and protrusions on the supporting wall 11 are engaged with each other to ensure the stability of the stacked retaining wall modules 1. The retaining wall modules 1 in the present invention are assembled with a total of 4 layers, and the water reservoir 2 is arranged on the top layer of the retaining wall module 1. The water reservoir 2 is connected to the drip irrigation assembly. When water is stored in the water reservoir 2, the water source will enter the drip irrigation assembly through the water reservoir 2, and the drip irrigation assembly will pass through all the retaining wall modules 1 through the through hole and transport the water source to the soil layer in the retaining wall module 1. The specific effect of the above implementation method is that, through the principle of communicating vessels, the water source enters the drip irrigation assembly through the water reservoir 2, and finally the water source drips to the surface of the soil layer to realize non-powered drip irrigation.

[0055] like Figure 4 and Figure 5As shown, the drip irrigation assembly includes a plurality of branch pipes 32 and a main pipe 31 . The branch pipes 32 are connected to the main pipe 31 through pipe joints. The branch pipes 32 are arranged on both sides of the main pipe 31 .

[0056] like Figure 4 As shown, one end of the branch pipe 32 away from the main pipe 31 is connected to a water storage pipe 33 through a pipe joint, and the pipe mouth of the water storage pipe 33 faces directly upward.

[0057] like Figure 4 As shown, the water storage pipe 33 is a U-shaped structure, the water storage pipe 33 is arranged in the soil layer, the top of the water storage pipe 33 is at a distance from the soil layer, a drip irrigation pool 4 is arranged at the top of the water outlet of the water storage pipe 33, the bottom surface of the drip irrigation pool 4 is provided with a water inlet hole connected to the inner cavity of the water storage pipe 33, a plurality of drip holes 42 are opened on the outer wall of the drip irrigation pool 4, the diameter of the drip hole 42 is 0.4mm, and the water storage pipe 33 is made of corrosion-resistant metal.

[0058] like Figure 7 and Figure 8 As shown, a float valve 41 is provided at the water inlet, and the liquid level height when the float valve 41 is closed is higher than the height of the drip hole 42 .

[0059] like Figure 6 As shown, a water-absorbing cotton rope 34 is arranged in the water storage pipe 33. The water-absorbing cotton rope 34 passes through the inner cavity of the water storage pipe 33, penetrates the water diversion channel of the float valve 41, passes through the drip irrigation pool 4 and is buried in the soil layer.

[0060] like Figure 5 As shown, the main pipe 31 and the branch pipe 32 are both straight cylindrical structures, and the water storage pipe 33 is a U-shaped structure. In the present invention, the main pipe 31 and the branch pipe 32 located at the bottom layer are connected through a three-way pipe joint, and both sides of the branch pipe 32 are also connected to the branch pipe 32 through an elbow pipe joint. Therefore, the main pipe 31 and the branch pipe 32 located at the bottom layer also form a U-shaped structure, and the main pipe 31 and the branch pipe 32 on the upper three layers of the present invention are connected to each other through a four-way pipe joint, and the two ends of the branch pipe 32 away from the main pipe 31 are connected to the water storage pipe 33 through elbow pipe joints.

[0061] Specifically, when there is water in the water reservoir 2, according to the communicating vessel principle, water flows along the bottom surface of the water reservoir 2 into the main pipe 31. Under the action of gravity, the water in the main pipe 31 flows to the branch pipes 32 on both sides. The bottom branch pipe 32 is connected to the main pipe 31 through a tee and an elbow communicating vessel. An outlet pipe is provided at one end of the bottom branch pipe 32 away from the main pipe 31, so that the bottom branch pipe 32 forms a U-shaped water storage structure. The branch pipes 32 of other layers are connected to the water storage pipes 33. The water storage pipes 33 are U-shaped structures. The water source flowing into the branch pipes 32 will enter the outlet pipe or the water storage pipe 33. The water in the bottom branch pipes 32 first fills the inner cavity of the branch pipes 32 and continues to flow into the The outlet pipe is connected to a drip irrigation pool 4, and a float valve 41 is provided in the drip irrigation pool 4. When the outlet pipe flows into the drip irrigation pool 4, water will pass through the float valve 41, and the float valve 41 will introduce water into the drip irrigation pool 4. When the liquid level in the drip irrigation pool 4 reaches a certain height, the float valve 41 is closed, and the outlet pipe no longer continues to supply water to the drip irrigation pool 4. While the water in the main pipe 31 flows to the bottom branch pipe 32, it will also flow into the inside of the branch pipes 32 on other layers. The drip irrigation pool 4 on the bottom layer is first filled with a certain amount of water source, and then the drip irrigation pool 4 on each layer is gradually filled with a certain amount of water source from low to high. The water in the branch pipe 32 flows into the water storage pipe 33, and the water in the water storage pipe 33 flows into the connected drip irrigation pool 4.

[0062] The water storage pipe 33 includes a first pipe, a second pipe and a third pipe connected to each other through an elbow communicating device. The first pipe is connected to the branch pipe 32, one end of the third pipe is connected to the drip irrigation pool 4, the second pipe is connected to the end of the third pipe away from the drip irrigation pool 4, and the other end of the second pipe is connected to the end of the first section pipe away from the branch pipe 32. The first pipe, the second pipe and the third section pipe are combined into a U-shaped structure. After the water source enters the branch pipe 32 connected to the first pipe, according to the communicating device principle, the water source in the branch pipe 32 first enters the first pipe perpendicular to it, followed by the water source in the first pipe entering the second pipe, and finally the water in the second pipe enters the third pipe. As the water entering the second pipe gradually increases, the liquid level of the water in the third pipe will gradually rise and enter the drip irrigation pool 4 through the float valve 41.

[0063] The initial state of the drip irrigation pool 4 is that there is no water source. The float of the float valve 41 cannot float without water source, resulting in that the push rod of the float cannot resist the valve stem of the float valve 41, causing the valve to be in the open state. The water in the third connecting pipe continues to rise under the action of pressure and is slowly injected into the drip irrigation pool 4 through the channel of the float valve 41. When the liquid level of the water source in the drip irrigation pool 4 rises, the float will also rise. When the liquid level in the drip irrigation pool 4 submerges the drip hole 42, the water source in the drip irrigation pool 4 will overflow from the drip hole 42. The diameter of the drip hole 42 is 0.4mm, and the water source in the water storage pipe 33 flows fast. Therefore, the water at the drip hole 42 drips along the outer wall of the drip irrigation pool 4 to the surface of the soil layer in a drip-like manner to moisten the soil layer. The water inlet speed in the drip irrigation pool 4 is greater than the dripping speed of the drip hole 42. Therefore, the final liquid level in the drip irrigation pool 4 will The height of the drip irrigation pool 4 is higher than the drip hole 42. When the liquid level in the drip irrigation pool 4 reaches the set value of the float valve 41, the float has floated to the highest point, and the push rod of the float will push the valve stem of the float valve 41. The end of the valve stem blocks the pipe mouth of the float valve 41. The float valve 41 is closed, and the water source in the water storage pipe 33 can no longer be injected into the channel of the float valve 41 through the water diversion hole. The working principle of the branch pipe 32 and the drip irrigation pool 4 at the bottom layer is the same as the above content. After the float valve 41 is closed, the drip irrigation pool 4 of each layer of the ecological retaining wall can be drip-irrigated at the same drip irrigation speed, and the water output intensity of the drip hole 42 will not be affected by low or high pressure, and the drip irrigation method can keep the soil layer moist for a long time, and will not dry out the vegetation in the soil layer. In addition, this watering method can achieve the watering effect without the need for power sources such as electricity.

[0064] A water-absorbing cotton rope 34 is provided inside the bottom of the water storage pipe 33, one end of the water-absorbing cotton rope 34 is located on the inner circumferential wall of the bottom of the water storage pipe 33, and the other end passes through the pipeline of the float valve 41 along the inner cavity of the water storage pipe 33 to enter the drip irrigation tank 4, and finally the end thereof is buried in the soil layer through the drip irrigation tank 4. The water-absorbing cotton rope 34 is flexible and extensible, and the water-absorbing cotton rope 34 can use its own water absorption to lead the water source in the water storage pipe 33 to the soil layer. In dry weather, when the water source in the water storage tank 2 dries up, the water-absorbing cotton rope 34 can continue to irrigate the soil layer, so that in the case of drought and water shortage, the present invention can still keep the local area of ​​the soil layer moist.

[0065] The absorbent cotton rope 34 passes through the pipeline of the float valve 41. The end of the valve stem in the float valve 41 is made of rubber material and is used to seal the pipeline of the float valve 41. When the liquid level in the drip irrigation pool 4 reaches the set value of the float valve 41, the valve stem will block the pipeline of the float valve 41 and squeeze the absorbent cotton rope 34. The absorbent cotton rope 34 is deformed after being compressed and cannot continue to absorb water. When the water source in the drip irrigation pool 4 is exhausted, the float of the float valve 41 falls, the valve stem opens, and the absorbent cotton rope 34 can continue to absorb water. In addition, even if the absorbent cotton rope 34 affects the airtightness of the valve stem of the float valve 41, due to the good flexibility and ductility of the absorbent cotton rope 34 and the soft rubber material of the end of the valve stem, the water in the water storage pipe 33 will only rise slowly, and several drip holes 42 will also drip at the same time, and the two will reach a stable state, which will not cause the water source to overflow along the drip irrigation pool 4.

[0066] A water pump is provided on one side of the retaining wall module 1 , the output port of the water pump is connected to a water diversion pipe, and the other end of the water diversion pipe is located directly above the water reservoir 2 .

[0067] like Figure 1 and Fig. 9 As shown, a cover plate 21 is provided at the top of the water reservoir 2, and a through groove is opened in the center of the cover plate 21.

[0068] like Figure 1 and Fig. 9 As shown, the top surface of the cover plate 21 is recessed downward toward the center of the cover plate 21 , and the side of the cover plate 21 facing the water reservoir 2 is covered with a waterproof tape.

[0069] Specifically, after the retaining wall module 1 is assembled as an ecological retaining wall, water can be transported into the water reservoir 2 through a water pump. When the water reservoir 2 is filled, the drip irrigation system and the drip irrigation pool 4 can reach a stable value. When it rains, rainwater will flow into the water reservoir 2 through the cover plate 21. When the water in the water reservoir 2 evaporates and turns into water vapor, it will form water droplets on the waterproof tape on the bottom of the cover plate 21. As the volume of the water droplets increases, they will fall back into the water reservoir 2, which can slow down the evaporation of the water source in the water reservoir 2.

[0070] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
