Abstract
Description
Technical Field
[0001] This utility model relates to the field of irrigation and drainage technology, and in particular to an ecological tree pool structure and an ecological tree pool irrigation system. Background Technology
[0002] Ecological tree pits, as small-scale bioretention facilities, are typically installed along municipal roads and in parks or residential green spaces. The existing structure of ecological tree pits involves laying a waterproof geotextile first, then a sand and gravel filter layer, followed by a permeable geotextile, and finally covering it with planting soil. Drainage pipes are located within the sand and gravel filter layer. While this structure can serve both water storage and irrigation purposes, it relies on rainwater infiltration from the ground, resulting in low water storage efficiency and a tendency to clog. Furthermore, its water storage capacity is limited, necessitating the use of surface sprinkler irrigation.
[0003] Based on this, this application provides an ecological tree pit structure and an ecological tree pit irrigation system that can efficiently utilize rainwater or self-replenishment and are not easily clogged to solve the above problems. Utility Model Content
[0004] This invention aims to solve the technical problems existing in the prior art. Therefore, this invention provides an ecological tree pit structure and ecological tree pit irrigation system that can efficiently utilize rainwater or self-replenishment and is not easily clogged.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] In a first aspect, an ecological tree pool structure is provided, including an ecological tree pool and a water storage tank located at the bottom of the ecological tree pool. The top of the water storage tank is provided with an inwardly recessed pit for planting trees. The bottom surface of the pit is provided with a channel that communicates with the inner cavity of the water storage tank. Sand and gravel are filled into the water storage tank through the channel to form a filter layer. The side wall of the water storage tank is provided with an inlet and an overflow that communicate with its inner cavity, and the overflow is higher than the opening channel.
[0007] In some alternative embodiments, the bottom surface of the pit is also provided with a permeable geotextile to prevent planting soil from entering the filter layer from the channel and clogging the filter layer.
[0008] In some alternative implementations, the overflow outlets of the water storage tanks in two adjacent ecological tree pools are connected to the inlet via gravity flow pipes.
[0009] In some alternative implementations, the inlet of the water tank in the highest ecological tree pool is connected to a water supply pipe, and the overflow outlet of the water tank in the lowest ecological tree pool is connected to a municipal drainage pipe.
[0010] Secondly, an ecological tree pool irrigation system is provided, including the aforementioned ecological tree pool structure, a water storage tank, a first level gauge, and a water supply electric valve. The outlet of the water storage tank is connected to the inlet of the water storage tank in the highest ecological tree pool through a gravity flow pipe. The water supply electric valve is located at the outlet of the water storage tank. The first level gauge is located on the water storage tank in the lowest ecological tree pool for monitoring the water level in the tank. The overflow outlet of the water storage tank in the lowest ecological tree pool is connected to a municipal drainage pipe.
[0011] In some alternative embodiments, the bottom of the water storage tank is covered with a layer of sand and gravel, and the tank is further divided into a rainwater area and a clean water area by longitudinal partitions. The water inlet of the water storage tank is located in the rainwater area, and the water outlet is located in the clean water area and above the sand and gravel layer.
[0012] In some optional embodiments, the water purification area is further provided with a water supply pipe and a second level gauge, and the water supply pipe is provided with a water supply electric valve.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model achieves water storage in ecological tree pools by setting up water storage tanks in the ecological tree pools. Each water storage tank is connected by gravity flow pipes according to the terrain elevation. When rainwater is scarce, it can quickly replenish water in all the water storage tanks in the ecological tree pools. Compared with the ground sprinkler irrigation method for ecological tree pools, the water replenishment efficiency is high and it also saves manpower and material resources.
[0015] 2. Water storage tanks are used for irrigation, with the water level inside higher than the permeable geotextile. This allows the permeable geotextile to have upward water pressure when water is added, preventing mud and water from settling and clogging the permeable geotextile.
[0016] 3. By using prefabricated water tanks installed in the ecological tree pools, trees can be planted directly in the ecological tree pools. This method greatly improves construction efficiency compared to traditional construction methods. Attached Figure Description

[0028] Example 1
[0029] As attached Figure 1 and attached Figure 2 As shown, this embodiment provides an ecological tree pool structure, including an ecological tree pool 1 and a water storage tank 2 located at the bottom of the ecological tree pool. The top of the water storage tank 2 has an inwardly recessed pit 2.1 for planting trees. The bottom surface of the pit 2.1 has a channel 2.2 communicating with the inner cavity of the water storage tank. Sand and gravel are filled into the water storage tank through the channel 2.2 to form a filter layer 2.3. The side wall of the water storage tank 2 has an inlet 2.4 and an overflow 2.5 communicating with its inner cavity. The inlet is not lower than the overflow, and the overflow is higher than the opening channel. The inlet of the water storage tank is used to inject irrigation water into the water storage tank, and the overflow is used to overflow excess water. The water in the water storage tank enters the planting soil through the channel for irrigating the trees.
[0030] In practice, the water storage tank and its internal filter layer are prefabricated, then placed at the bottom of the ecological tree pit, and finally the trees are planted. Compared with traditional construction methods, this construction method greatly improves construction efficiency. At the same time, this ecological tree pit structure meets the requirements for rainwater storage and drainage, and also facilitates water replenishment through buried pipes, eliminating the need for surface sprinkler irrigation during the dry season.
[0031] Preferably, the bottom surface of the recess 2.1 is also provided with a permeable geotextile 2.6 to isolate the planting soil 3 from the filter layer 2.3, preventing the planting soil from entering the filter layer from the channel and clogging the filter layer. Since the water level in the water tank is higher than that of the permeable geotextile, the permeable geotextile can have upward water pressure when water is added, avoiding the sedimentation of mud and water and clogging of the permeable geotextile.
[0032] Preferably, the overflow outlets 2.5 of the water storage tanks 2 in two adjacent ecological tree pools 1 are connected to the inlets 2.4 via gravity flow pipes 4. Specifically, the overflow outlets of the water storage tanks in two adjacent ecological tree pools with the same elevation are connected to the inlets via gravity flow pipes, and the overflow outlets of the water storage tanks in the ecological tree pools with higher elevations are connected to the inlets of the water storage tanks in the ecological tree pools with lower elevations via gravity flow pipes. The inlet 2.4 of the water storage tank 2 in the ecological tree pool with the highest elevation is connected to the water supply pipe 5, and the overflow outlet 2.5 of the water storage tank 2 in the ecological tree pool with the lowest elevation is connected to the municipal drainage pipe 6, thus forming a water network connecting all the ecological tree pools.
[0033] During the rainy season, rainwater seeps into the storage tank and is stored there. Excess rainwater overflows into the municipal drainage network without affecting the water storage and drainage functions of the ecological tree pits. During the dry season, irrigation water is replenished to the storage tanks in each ecological tree pit through water supply pipes. Replenishing water is convenient, quick, and saves time and effort.
[0034] It is worth noting that the shape of the water tank in the accompanying drawings of this embodiment is only one example and does not limit the water tank of this application. Other water tank structures with recesses and internal cavities are also within the protection scope of this application.
[0035] Example 2
[0036] This embodiment provides an ecological tree pit irrigation system, as shown in the attached figure. Figure 3 As shown, the structure includes the ecological tree pool structure described in Embodiment 1, a water storage tank 7, a first level gauge 8, and a water supply electric valve 9. The outlet of the water storage tank 7 is connected to the inlet 2.4 of the water storage tank 2 in the ecological tree pool 1, which is at the highest elevation, through a gravity flow pipe 4. The water supply electric valve 9 is located at the outlet of the water storage tank 7. The first level gauge 8 is located on the water storage tank 2 in the ecological tree pool 1, which is at the lowest elevation, and is used to monitor the water level in the water storage tank. The overflow port of the water storage tank in the ecological tree pool at the lowest elevation is connected to the municipal drainage pipe.
[0037] Working principle: The water level in the lowest ecological tree pool is detected by the first level gauge. When it is lower than the set value, the water supply electric valve is opened to replenish the water in the ecological tree pool with the water stored in the storage tank. The water supply electric valve is closed when the water level detected by the first level gauge reaches the set value, thus completing the automatic water replenishment operation.
[0038] Preferably, the bottom of the water storage tank 7 is lined with a layer of sand and gravel 7.1, and the tank is further divided into a rainwater area and a clean water area by longitudinal partitions 7.2. The water inlet of the water storage tank is located in the rainwater area, and the water outlet is located in the clean water area and above the sand and gravel layer. The top of the water storage tank is provided with a vent 7.3. In this embodiment, the water inlet of the water storage tank 7 is connected to a rainwater collection trough. Rainwater collected through the rainwater collection trough flows into the water storage tank for storage. The sand and gravel layer inside the water storage tank is used to filter rainwater, and only the rainwater area needs to be cleaned periodically.
[0039] Preferably, the water purification area is further equipped with a water supply pipe 10 and a second level gauge 11, and the water supply pipe 10 is equipped with a water supply electric valve 12. This embodiment further includes a water supply pipe, which allows for water replenishment to the water storage tank during the dry season. The second level gauge detects the water level in the storage tank, and the water supply electric valve is controlled to automatically replenish water, ensuring a certain amount of irrigation water in the storage tank to meet the irrigation needs of each ecological tree pool.
[0040] It is worth noting that all the above controls are automatically controlled by the host computer in the control room. The water supply electric valve is equipped with a signal receiving and recording device. It opens after receiving a signal and records the opening time. If it does not open for a long time, an alarm will be triggered to prevent system failure.
[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
