Description

Technical Field

[0001] This invention relates to the field of ecological tree pit technology for large ancient trees, and more specifically, to an ecological tree pit suitable for large ancient trees and a method for its renovation. Background Technology

[0002] With the acceleration of urbanization, the number of impermeable surfaces has increased dramatically, cutting off the original infiltration channels of rainwater, greatly reducing the amount of rainfall infiltration, increasing the peak of rainstorms, and shortening the runoff time. Therefore, for large ancient trees, ecological tree pits are needed for watering to improve the appearance of large ancient trees and enhance drainage.

[0003] The invention patent with publication number CN113179793A in the existing references discloses a water-saving ecological tree pool for the protection of ancient trees and its control method. It belongs to the field of tree pool technology. It includes an ancient tree, a tree pool at the lower end of the ancient tree, a water collection tank at the lower end of the tree pool, a water spray ring pipe at the upper end of the tree pool, a water pump on the side of the water spray ring pipe, a water supply pipe between the water pump and the water spray ring pipe, a water pumping pipe between the water pump and the water collection tank, several downpipes connected to the water collection tank around the tree pool, several drainage pipes between the downpipes and the tree pool, a water-proof embankment between the tree pool and the water spray ring pipe, a drainage ring ditch connected to the downpipes around the water-proof embankment, a protective frame connected to the ancient tree at the upper end of the water-proof embankment, and a liquid replenishment component between the water pump and the water-proof embankment.

[0004] However, when using the aforementioned ecological tree pool, the overall renovation and construction requires measurement and installation at each point. Furthermore, the tree pool and the water-resistant embankment need to be excavated according to the specified dimensions, and then filled and constructed according to the specified dimensions. Therefore, the construction and renovation require measurement at each point. Moreover, the water stored inside evaporates significantly due to direct sunlight, affecting the use of ecological circulating water. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an ecological tree pit suitable for large ancient trees and a method for its transformation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ecological tree pool suitable for large ancient trees, comprising two symmetrically arranged edge positioning frames, wherein positioning support plates are inserted inside the edge positioning frames and near their two corners, one end of each positioning support plate is provided with a positioning mechanism, and one side of the arc-shaped positioning strip is provided with a positioning filling component. The positioning mechanism includes an arc-shaped positioning strip at one end of the positioning support plate. A T-shaped positioning block is welded to one end of each arc-shaped positioning strip. A connecting recess and a docking recess are provided on the lower surface of the edge positioning frame. A bottom fixing frame is provided on the lower surface of the connecting recess. A welded support recess is provided on the lower surface of the docking recess. An anti-evaporation mechanism is provided inside both the bottom fixing frame and the support recess.

[0007] Preferably, the multiple arc-shaped positioning strips are welded and fixed one-to-one with the multiple arc-shaped positioning strips, and both the arc-shaped positioning strips and the positioning support plate are made of stainless steel. Adjacent arc-shaped positioning strips are detachably snapped together by T-shaped positioning blocks, and the cross-sectional shape of the T-shaped positioning blocks is set to T-shape. The connecting concave frame and the docking concave frame are slidably inserted together, and the bottom fixing frame and the supporting concave frame are slidably inserted together. Two positioning rods are fixed on the lower surface of the bottom fixing frame and the supporting concave frame. The outer wall of each positioning rod is fixed with multiple insert blades in a circular ring at equal intervals, and one side of the insert blades is treated with a right angle.

[0008] Preferably, the bottom of the connecting recess, the bottom fixing frame, the docking recess, and the supporting recess are all embedded with through-holes for positioning, and positioning pins that are fixedly connected to the edge positioning frame are installed inside the positioning holes. The positioning pins are slidably connected to the connecting recess and the bottom fixing frame.

[0009] Preferably, the positioning and filling component includes a pebble covering layer on one side of the arc-shaped positioning strip, a green cold-mix asphalt layer on one side at the position between two adjacent positioning support plates, a granite positioning strip on one side of the green cold-mix asphalt layer laid inside the edge positioning frame, a dead wood nourishing layer covering and filling the lower surface of the green cold-mix asphalt layer, and a soil planting layer at the bottom of the dead wood nourishing layer.

[0010] Preferably, the anti-evaporation mechanism includes a water storage tank installed inside the bottom fixed frame, and the inside of the water storage tank is provided with a connecting pipe. The top end of the connecting pipe is welded to an upper connecting pipe. A threaded ring is fitted on the outer wall of the upper connecting pipe near its top end. A fixed support is fixed to one side of the inner wall of the water storage tank. A sealing cover is rotatably connected to the outer wall of the fixed support. One side of the sealing cover is provided with a protective plate for filtering the water seeping into the soil planting layer, and one side of the protective plate has multiple water-permeable micropores. The upper surface of the sealing cover is rounded, and the sealing cover is made of stainless steel.

[0011] A method for transforming ecological tree pits suitable for large ancient trees, with the following specific steps: Step 1: During positioning and installation, the bottom fixing frame can be placed on one side of the large ancient tree, and the supporting recessed frame can be placed on the other side of the large ancient tree. The upper surface of the bottom fixing frame and the upper surface of the supporting recessed frame can be tapped, and the positioning rod can be squeezed into the soil. The positioning rod drives multiple insert blades to insert into the soil to complete the embedding and insertion. Then, the connecting recessed frame and the docking recessed frame are connected and spliced ​​above the bottom fixing frame and the supporting recessed frame. The two edge positioning frames are spliced, and the edge positioning frames drive two positioning pins to insert into the positioning holes to complete the positioning and insertion. After splicing, the four arc-shaped positioning strips can be spliced ​​downward one by one. The positioning support plate can be inserted into the corner of the inner wall of the edge positioning frame to achieve positioning and installation. This can quickly form the positioning and splicing assembly of the ecological pond. Step 2: During positioning and filling, pour the soil planting layer into the rectangular gap between the bottom fixed frame and the supporting concave frame to fill the soil planting layer. The soil planting layer should be filled to the height of the top surface of the bottom fixed frame. Then, continue to fill the rectangular gap between the connecting concave frame and the docking concave frame with the deadwood nutrient layer. The height of the top surface of the deadwood nutrient layer should be the same as the top surface of the bottom fixed frame. Next, lay the green cold-mix asphalt layer in the gap between the two positioning plates. Four green cold-mix asphalt layers can be laid at a time. Then, lay granite positioning strips on the inner wall of the edge positioning frame. The granite positioning strips can provide downward support for the edge positioning frame and increase its stability. Fill the area of ​​the circle formed by the four arc-shaped positioning strips with a pebble covering layer. This can increase the road surface strength through the green cold-mix asphalt layer, and water can seep into the root and stem parts of large ancient trees through the pebble covering layer. The deadwood nutrient layer can transport nutrients to the deadwood, and the soil planting layer can supply soil nutrients as a planting layer. Step 3: During rainwater collection and evaporation prevention, in heavy rain, rainwater seeps through the pebble covering layer into the deadwood nutrient layer, and then into the soil planting layer. Due to the large amount of rainwater, when the entire soil planting layer is filled, the rainwater enters the protective plate. Through multiple permeable micropores, the rainwater is transported to the gap between the sealing cover and the protective plate. Under the pressure of the rainwater, the sealing cover is squeezed, causing it to rotate upwards on the outer wall of the fixed support. This creates a gap between the sealing cover and the water storage tank, allowing rainwater to enter and fill the tank. When the tank is full of water, the water pressure inside and outside is the same. Therefore, the sealing cover rotates downwards on the outside of the fixed support, so that the sealing cover can be squeezed and fitted to the side of the tank to seal the opening. As a result, the water inside the tank does not easily evaporate in hot weather. In summer, the pump pipe is connected to the threaded ring. The threaded ring creates suction in the connecting pipe, which draws the rainwater stored inside the tank into the upper pipe. The water is then discharged to the location of the large ancient tree through the upper pipe, realizing drip irrigation and forming a rainwater ecological cycle. The storage time is longer and the water will not evaporate during droughts.

[0012] The technical effects and advantages of this invention are as follows: 1. This invention uses a positioning mechanism to place the bottom fixed frame on one side of a large ancient tree, while the supporting concave frame is located on the other side of the large ancient tree. The upper surfaces of the bottom fixed frame and the supporting concave frame are tapped to achieve docking. The connecting concave frame and the docking concave frame are docked. The positioning support plate can be inserted into the corner of the inner wall of the edge positioning frame to achieve positioning and installation. The arc-shaped positioning strip can form a circular positioning splice. This multi-point rapid positioning and splicing allows for rapid construction of ecological tree pools during the renovation process, thus improving construction efficiency. 2. This invention uses a positioning and filling component to pour the soil planting layer into the rectangular gap between the bottom fixed frame and the supporting recessed frame. The soil planting layer filling height is located at the height of the upper surface of the bottom fixed frame. The green cold-mixed asphalt layer is laid in the gap between the two positioning support plates. Four green cold-mixed asphalt layers are laid at one time. Granite positioning strips are laid on the inner wall of the edge positioning frame and filled with a pebble covering layer. Corresponding ecological soil and ecological pebbles can be filled in each enclosed area. The ecological tree pool filling material required for positioning and filling at designated locations is faster and does not require location measurement. 3. The present invention uses an anti-evaporation mechanism so that when rainwater fills the entire soil planting layer, the rainwater enters the protective plate. Multiple permeable micropores can transport the rainwater to the gap between the sealing cover and the protective plate. The rainwater squeezes the sealing cover to rotate upward on the outer wall of the fixed support. In high-temperature weather, the water inside the water storage tank is not easy to evaporate, resulting in better ecological water retention. More water is stored during droughts, the water collection and storage time is longer, and the ecological water recycling is more sustainable. The integrated assembly of water storage does not require individual installation, and the overall molding and transformation efficiency is higher. In summary, through the interaction of the above-mentioned multiple functions, multi-point rapid positioning and splicing allows for the rapid construction of ecological tree pools during the renovation process. This results in faster construction efficiency. The corresponding ecological soil and ecological pebbles are filled into each enclosed area, and the required ecological tree pool filler is filled at designated locations more quickly without the need for location measurement. The integrated assembly and water storage eliminates the need for individual installations, and the overall molding and renovation efficiency is higher. In summary, this effectively improves the renovation and construction efficiency of ecological water pools, as well as the sustainability of ecological water circulation. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] As attached Figure 1-6 The diagram shows an ecological tree pool suitable for large ancient trees. This ecological tree pool is equipped with a positioning mechanism and a positioning filling component. The design of these mechanisms and components effectively improves the construction efficiency of the ecological water pool renovation and the sustainability of the ecological water circulation.

A supporting recess 8 is welded on the lower surface of the docking recess 7. An anti-evaporation mechanism is provided inside the bottom fixing frame 6 and the supporting recess 8. Multiple arc-shaped positioning strips 3 are welded and fixed to each other in a one-to-one correspondence. Both the arc-shaped positioning strips 3 and the positioning support plate 2 are made of stainless steel. Two adjacent arc-shaped positioning strips 3 are detachably snapped together by a T-shaped positioning block 4. The cross-sectional shape of the T-shaped positioning block 4 is T-shaped.

[0022] In some embodiments, as shown in the appendix Figure 3 As shown, two positioning rods 9 are fixed to the lower surfaces of the bottom fixing frame 6 and the supporting recessed frame 8. Each positioning rod 9 has multiple insert blades 10 fixed in a circular, equidistant arrangement on its outer wall. One side of each insert blade 10 is beveled to facilitate striking the upper surfaces of the bottom fixing frame 6 and the supporting recessed frame 8. The positioning rods 9 can be squeezed into the soil, and the multiple insert blades 10 are inserted into the soil to complete the embedding and connection. The bottom ends of the connecting recessed frame 5, the bottom fixing frame 6, the docking recessed frame 7, and the supporting recessed frame 8 are all embedded with through-holes 11. The positioning holes 11 are equipped with positioning posts 12 that are fixedly connected to the edge positioning frame 1. The positioning posts 12 are slidably connected to the connecting recessed frame 5 and the bottom fixing frame 6, so that the edge positioning frame 1 can drive the two positioning posts 12 to insert into the positioning holes 11 to complete the positioning and connection, thus completing the positioning and docking function.

[0023] In some embodiments, as shown in the appendix Figure 1-4As shown, the positioning and filling component includes a pebble covering layer 13 set on one side of the arc-shaped positioning strip 3, a green cold-mixed asphalt layer 14 laid on one side between two adjacent positioning support plates 2, a granite positioning strip 15 laid inside the edge positioning frame 1 on one side of the green cold-mixed asphalt layer 14, a dead wood nourishing layer 16 covering the lower surface of the green cold-mixed asphalt layer 14, and a soil planting layer 17 at the bottom end of the dead wood nourishing layer 16.

[0024] In some embodiments, as shown in the appendix Figure 4-6 As shown, the anti-evaporation mechanism includes a water storage tank 18 installed inside the bottom fixed frame 6, and a connecting pipe 19 is provided inside the water storage tank 18. The top end of the connecting pipe 19 is welded to an upper connecting pipe 20. A threaded ring 21 is fitted on the outer wall of the upper connecting pipe 20 near its top end. A fixed support column 22 is fixed on one side of the inner wall of the water storage tank 18. A sealing cover plate 23 is rotatably connected to the outer wall of the fixed support column 22. A protective plate 24 is provided on one side of the sealing cover plate 23 for filtering the water permeating the soil planting layer 17. A plurality of water-permeable micropores 25 are opened on one side of the protective plate 24. The upper surface of the sealing cover plate 23 is rounded, and the sealing cover plate 23 is made of stainless steel.

[0025] Working principle of this invention: During positioning and installation, the bottom fixing frame 6 can be placed on one side of the large ancient tree, and the supporting recessed frame 8 can be placed on the other side of the large ancient tree. The upper surface of the bottom fixing frame 6 and the upper surface of the supporting recessed frame 8 can be tapped, and the positioning rod 9 can be squeezed into the soil. Multiple insert blades 10 are inserted into the soil to complete the embedding and insertion. Then, the connecting recessed frame 5 and the docking recessed frame 7 are docked, and the two edge positioning frames 1 are spliced. The positioning support plate 2 can be inserted into the corner of the inner wall of the edge positioning frame 1 to achieve positioning and installation. During positioning and filling, the soil planting layer 17 can be poured into the rectangular gap between the bottom fixed frame 6 and the supporting recessed frame 8. The filling height of the soil planting layer 17 should be at the height of the upper surface of the bottom fixed frame 6. The dead wood nourishing layer 16 can be filled into the rectangular gap formed between the connecting recessed frame 5 and the connecting recessed frame 7. The green cold-mixed asphalt layer 14 can be laid in the gap between the two positioning support plates 2. Four green cold-mixed asphalt layers 14 can be laid at one time. Granite positioning strips 15 are laid on the inner wall of the edge positioning frame 1 to increase the stability of the edge positioning frame 1. The area of ​​the ring formed by the four arc-shaped positioning strips 3 is filled with a pebble covering layer 13. When collecting rainwater to prevent evaporation, the rainwater seeps into the deadwood nutrient layer 16 along the pebble covering layer 13. Due to the large amount of rainwater, when the rainwater fills the entire soil planting layer 17, the rainwater enters the protective plate 24. Multiple permeable micropores 25 can transport the rainwater to the gap between the sealing cover 23 and the protective plate 24. The rainwater squeezes the sealing cover 23 to rotate upward on the outer wall of the fixed support 22, and the rainwater enters the water storage tank 18 to fill it. The water pressure inside and outside the water storage tank 18 is the same. The sealing cover 23 rotates downward on the outside of the fixed support 22. In high-temperature weather, the water inside the water storage tank 18 is not easy to evaporate. The connecting pipe 19 draws the rainwater stored inside the water storage tank 18 into the upper pipe 20, and discharges it to the location of the large ancient tree through the upper pipe 20 to realize drip irrigation. The following preliminary comparative implementation examples and specific modification steps are required during the above construction process; First, the original damaged surface coverings such as bricks were removed from the old tree pits, and the old tree pit curbs were also removed.

[0026] 2. Shape and compact the sidewalk around the tree pit, and level the curb stones to lay the foundation for the next renovation steps.

[0027] 3. For trees with a diameter of 40cm or more and a root thickness of 8-10cm, including surface protrusions and 10-15cm below the surface layer, manually cut off the roots and prune the roots that extend beyond the tree pit.

[0028] 4. After cutting the tree roots, apply a nourishing ointment by hand to help the pruned tree heal and maintain its wounds.

[0029] 5. Remove the excavated soil and pruned tree roots, and dispose of the stones.

[0030] 6. Backfill the planting soil according to the condition of the tree pit on site.

[0031] 7. Enclose the tree pit with a 60-meter fence. The 3mm thick stainless steel decorative strips, including the inner and outer frames and connecting strips, serve two purposes: firstly, to secure the cold-mix asphalt material and to provide a base space for the subsequent laying of pebbles; secondly, to allow for segmented repairs to be made in two to three years if the old tree roots grow and warp.

[0032] 8. Lay a reverse-seepage geotextile under the foundation of the stainless steel frame of the tree pit to prevent soil from seeping back and clogging the pores of the permeable tree pit after rainwater.

[0033] 9. Lay a 30mm thick layer of graded crushed stone on the laid reverse seepage geotextile to serve as the base layer for the cold-mixed asphalt surface layer.

[0034] 10. Pour a 60mm thick layer of cold-laid, high-viscosity, colored permeable asphalt onto the gravel base layer to serve as a tree pit cover. This serves both an aesthetic purpose and allows rainwater to infiltrate into the soil for absorption during rainy weather.

[0035] 11. Apply a single-component polyurethane protective agent to the surface of cold-mixed asphalt to achieve wear resistance and aesthetic appeal.

[0036] 12. Adding pebbles to the tree pit cover and between trees can achieve an aesthetic effect and also filter out some larger garbage and debris to prevent them from sinking to the bottom of the tree pit. Therefore, in this embodiment, the construction efficiency is higher and the speed is faster compared to the previous embodiment.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

Tap the upper surface of the bottom fixed frame (6) and the upper surface of the support recessed frame (8). The positioning rod (9) is squeezed into the soil, and the positioning rod (9) drives multiple insert blades (10) to be inserted into the soil to complete the embedding and insertion. Then, connect the concave frame (5) and the docking concave frame (7) to complete the splicing above the bottom fixed frame (6) and the support recessed frame (8). The two edge positioning frames (1) are spliced. The edge positioning frame (1) drives two positioning pins (12) to be inserted into the positioning hole (11) to complete the positioning and insertion. After splicing, the four arc-shaped positioning strips (3) are spliced ​​downward one by one. The positioning support plate (2) is inserted into the corner of the inner wall of the edge positioning frame (1) to complete the positioning and installation. In this way, the positioning and splicing assembly of the ecological pool is quickly formed. Step 2: During positioning and filling, pour the soil planting layer (17) into the rectangular gap between the bottom fixed frame (6) and the supporting recessed frame (8) to fill the soil planting layer (17). The filling height of the soil planting layer (17) is at the height position of the upper surface of the bottom fixed frame (6). Then, continue to fill the rectangular gap formed between the connecting recessed frame (5) and the connecting recessed frame (7) with the deadwood nourishing layer (16). The filling height of the upper surface of the deadwood nourishing layer (16) is the same as the position of the upper surface of the bottom fixed frame (6). Then, lay the green cold-mixed asphalt layer (14) in the gap between the two positioning support plates (2) in one go. Four green cold-mix asphalt layers (14) are laid. Then, granite positioning strips (15) are laid on the inner wall of the edge positioning frame (1). The granite positioning strips (15) provide downward support to the edge positioning frame (1), increasing the stability of the edge positioning frame (1). A cobblestone covering layer (13) is filled in the area enclosed by the four arc-shaped positioning strips (3). In this way, the green cold-mix asphalt layer (14) increases the road surface strength. Water seeps into the root and stem parts of the large ancient tree at the location of the cobblestone covering layer (13). The dead wood nutrient layer (16) transports dead wood nutrients, and the soil planting layer (17) serves as the planting layer to supply soil nutrients. Step 3: During rainwater collection and evaporation prevention, in heavy rain, rainwater seeps into the deadwood nutrient layer (16) along the pebble covering layer (13), and then enters the soil planting layer (17) from the deadwood nutrient layer (16). Due to the large amount of rainwater, when the rainwater fills the entire soil planting layer (17), the rainwater enters the protective plate (24) and is transported to the gap between the sealing cover (23) and the protective plate (24) through multiple permeable micropores (25). Under the pressure of the rainwater, the rainwater squeezes the sealing cover (23), and the sealing cover (23) rotates upward on the outer wall of the fixed support (22). In this way, a gap is created between the sealing cover (23) and the water storage tank (18), and the rainwater enters the water storage tank (18) to fill it. When the water storage tank ( 18) When the water inside the water tank (18) is full, the water pressure inside and outside the water tank (18) is the same. Therefore, the sealing cover (23) rotates downward on the outside of the fixed support (22). In this way, the sealing cover (23) presses against the side of the water tank (18) to seal the opening of the water tank (18). Therefore, the water inside the water tank (18) is not easy to evaporate in hot weather. In summer, the pump pipe is connected to the threaded ring (21). The threaded ring (21) causes the connecting pipe (19) to generate suction. The connecting pipe (19) sucks the rainwater stored inside the water tank (18) into the upper pipe (20). The rainwater is discharged to the location of the large ancient tree through the upper pipe (20) to realize drip irrigation operation, form a rainwater ecological cycle, and the storage time is longer. It will not evaporate during drought.
