Description

Technical Field

[0001] This utility model relates to the field of landscape road technology, specifically to a tree pit enclosure structure and a colored asphalt concrete ecological tree pit structure. Background Technology

[0002] Garden roads are common facilities in municipal construction. With the development and progress of technology, the requirements for the overall aesthetics and safety of garden cities are constantly increasing, and higher requirements are also placed on garden roads and their ancillary facilities. Therefore, the application of colored asphalt concrete in garden roads is becoming increasingly common. When colored asphalt concrete encounters tree pits during its application, current technology often uses bricks or stone structures to surround and retain water. However, due to factors such as construction technology, environmental climate, or drainage, the bricks or stone structures around the tree pits often crack, warp, or become uneven. The colored asphalt pavement around the tree pits also experiences gaps and cracks, seriously affecting the overall aesthetics of the road and posing safety hazards to vehicles or pedestrians.

[0003] Currently, the construction methods for tree pits attached to colored asphalt concrete roads still largely utilize larger, heavier, and more robust materials and construction techniques to enhance the strength of the tree pit's edging and water-retaining structure, preventing deformation and avoiding separation from the asphalt road surface due to compression or water seepage, which can lead to gaps and cracks. However, this also increases the manufacturing cost, and the abrupt, large-volume tree pit structure undermines the aesthetic, simple, smooth, and safe advantages of colored asphalt concrete pavements, thus reducing their visual quality and application effectiveness. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the prior art by providing a tree pit enclosure structure and a colored asphalt concrete ecological tree pit structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A tree pit enclosure structure includes a metal baffle. One side of the metal baffle is provided with a plurality of reinforcing tie rods, and the other side of the metal baffle is provided with an outer connecting side plate. The height of the reinforcing tie rods is higher than the height of the outer connecting side plate. The upper part of the metal baffle is also provided with a plurality of water-permeable holes, which are staggered from the reinforcing tie rods.

[0006] This tree pit enclosure structure is simple in structure, easy to manufacture and install. As a tree pit enclosure, it can leverage the advantages of combining with concrete to enhance mechanical properties and improve drainage performance. While meeting the growth needs of trees and plants, it reduces the long-term retention of rainwater under the road surface, prevents the road surface from loosening and causing separation, cracking, and other phenomena, and reduces the risk of road surface and tree pit collapse.

[0007] Furthermore, several of the reinforcing rods are arranged at equal intervals on the metal baffle, and several of the reinforcing rods on the same metal baffle are positioned at the same height.

[0008] Furthermore, water-permeable holes are provided between adjacent reinforcing tie rods, and the positions of the water-permeable holes are not lower than those of the reinforcing tie rods.

[0009] Furthermore, all the reinforcing tie rods are welded and fixed to the metal baffle. Both the outer connecting side plate and the metal baffle are cast iron plates. The outer connecting side plate is cast together with the metal baffle, or welded and fixed to the metal baffle.

[0011] A colored asphalt concrete ecological tree pit uses the tree pit enclosure structure as described above. The tree pit enclosure structure encloses and forms a tree pit. The tree pit is provided with a colored asphalt concrete surface layer, a colored asphalt concrete permeable layer, and a planting soil layer from top to bottom. The reinforcing tie rods extend into the colored asphalt concrete permeable layer. The permeable holes are located at the height of the colored asphalt concrete permeable layer. The outer connecting side plate is connected to the road surface structure outside the tree pit.

[0012] This colored asphalt concrete ecological tree pit fully considers the advantages of material performance and adopts the concept of ecological recycling, achieving good results in the following aspects.

[0013] First, the tree pit structure with permeable holes and functions solves the quality and safety hazards caused by slippery road surfaces due to long-term water accumulation in the road surface and tree pits during the rainy season. Second, the use of cast iron plates with reinforced tie rods as tree pit enclosures leverages the material advantages and tie structure to provide greater mechanical performance support, solving the problem of potential cracking and separation of the road surface and tree pits caused by tree root development and road load, thus reducing road collapse. Third, the use of thin-walled cast iron plates as tree pit enclosures, with permeable colored asphalt filling both the road surface and the inner surface of the tree pits, ensures that the colored pattern of the asphalt road surface is continuous with the inner surface of the tree pits, achieving an effect of enhancing the overall aesthetic appeal.

[0014] Furthermore, a permeable pipe is also provided below the planting soil layer.

[0015] Furthermore, the thickness of the colored asphalt concrete surface layer of the tree pit is less than the thickness of the colored asphalt concrete permeable layer of the tree pit, and the sum of the thicknesses of the colored asphalt concrete surface layer and the colored asphalt concrete permeable layer of the tree pit does not exceed half the vertical height of the metal baffle.

[0016] Furthermore, the road structure is provided from top to bottom as follows: a colored asphalt concrete surface layer, a colored asphalt concrete permeable layer, and a colored asphalt concrete subbase layer.

[0021] Example 1

[0022] like Figure 1 and Figure 2 As shown, a tree pit enclosure structure includes a metal baffle 1. A plurality of reinforcing tie rods 2 are provided on one side of the metal baffle 1, and an outer connecting side plate 3 is provided on the other side of the metal baffle 1. The height of the reinforcing tie rods 2 is higher than the height of the outer connecting side plate 3. The upper part of the metal baffle 1 is also provided with a plurality of water permeable holes 4, which are staggered from the reinforcing tie rods 2.

[0023] This tree pit enclosure structure is simple in structure, easy to manufacture and install. As a tree pit enclosure, it can leverage the advantages of combining with concrete to enhance mechanical properties and improve drainage performance. While meeting the growth needs of trees and plants, it reduces the long-term retention of rainwater under the road surface, prevents the road surface from loosening and causing separation, cracking, and other phenomena, and reduces the risk of road surface and tree pit collapse.

[0024] The metal enclosure 1 itself has superior mechanical properties, with good stability and strength. Combined with the reinforcing tie rods 2 and external connecting side plates 3 on both sides, its performance can be further improved. The reinforcing tie rods 2 can also bond with the concrete in the tree pit, enhancing the strength and stability of the concrete, preventing loosening, and reducing settlement. The external connecting side plates 3 can connect the tree pit enclosure with the surrounding road surface, forming an integrated structure with the road surface, further improving stability.

[0025] The permeable holes 4 are designed to guide water from the road surface and tree pits into the tree pits and discharge it through the drainage pipes inside the tree pits. This prevents water from accumulating on the road surface and in the tree pits and also solves the safety and quality hazards caused by long-term water accumulation on the road surface and in the tree pits during the rainy season.

[0026] Furthermore, several reinforcing rods 2 are arranged at equal intervals on the metal baffle 1, and several reinforcing rods 2 on the same metal baffle 1 are set at the same height position.

[0027] Through the above settings, the tree pit enclosure structure formed by the metal baffle 1 can be subjected to balanced forces, and together with these evenly distributed reinforcing tie rods 2, it can play a role in enhancing strength and stability.

[0028] Furthermore, water-permeable holes 4 are respectively provided between adjacent reinforcing tie rods 2. The water-permeable holes 4 are positioned at a position not lower than the reinforcing tie rods 2 to ensure that the water-permeable holes 4 can play a role in water drainage and drainage in the upper layer.

[0029] Furthermore, the reinforcing tie rods 2 are all welded and fixed to the metal baffle 1. The outer connecting side plate 3 and the metal baffle 1 are both cast iron plates. The outer connecting side plate 3 is cast together with the metal baffle 1, or welded and fixed to the metal baffle.

[0030] Tree pit enclosures made of cast iron (such as ductile iron, gray cast iron, etc.) have the advantage of providing a certain degree of earthquake resistance and are easy to manufacture. They can be mass-produced by casting, which is cost-effective. In addition, the outer connecting side plates can be cast together with the metal baffles, reducing the amount of work required for subsequent welding connections.

[0031] In some embodiments, the metal baffle 1 is a rectangular plate, and multiple rectangular plates are connected to form a rectangular tree pit enclosure; in other embodiments, the metal baffle 1 is an arc-shaped plate, and several arc-shaped plates are connected to form a ring-shaped tree pit enclosure.

[0032] Whether it is a rectangular tree pit enclosure or a circular tree pit enclosure, it can be manufactured according to actual needs. It can be assembled on-site or prefabricated in the factory and then transported to the site for installation.

[0033] Example 2

[0034] This embodiment provides a colored asphalt concrete ecological tree pit, which uses the tree pit enclosure structure as described in Embodiment 1, such as... Figure 3 As shown, the tree pit enclosure structure forms a tree pit. From top to bottom, the tree pit is provided with a tree pit colored asphalt concrete surface layer 5, a tree pit colored asphalt concrete permeable layer 6, and a tree pit planting soil layer 7. The reinforcing tie rods 2 extend into the tree pit colored asphalt concrete permeable layer 6. The permeable holes 4 are located at the height of the tree pit colored asphalt concrete permeable layer 6. The outer connecting side plate 3 is connected to the road surface structure outside the tree pit.

[0035] By using the aforementioned tree pit enclosure structure, the colored asphalt concrete ecological tree pit not only fulfills the function of ancillary tree pits along garden roads, but also enhances the aesthetic effect together with the colored asphalt concrete pavement. By setting a cast iron plate with permeable holes 4 and reinforcing tie rods 2 between the colored asphalt concrete pavement and the tree pit, the permeable colored asphalt pavement is flush with the permeable colored asphalt concrete surface filled in the tree pit. This allows the colored pattern of the asphalt concrete pavement to be continuous with the inner surface of the tree pit, achieving the effect of enhancing the overall aesthetic appeal. It also allows water from the road surface and the tree pit to be channeled or seeped into the tree pit, which can meet the growth needs of trees and plants, and allow excess water to seep into the ground and be discharged through permeable pipes, thereby reducing the long-term retention of water under the road surface, preventing the road surface from loosening and causing separation, cracking, and reducing road collapse.

[0036] In this embodiment, the permeable hole 4 and the reinforcing tie rod 2 are basically at the same height. Since the reinforcing tie rod 2 is to be connected to the permeable concrete, the permeable hole 4 is located within the permeable concrete area and can play its role in drainage and water diversion.

[0037] Furthermore, a permeable pipe 8 is provided below the planting soil layer 7. The permeable pipe 8 can be used to drain excess water that has seeped into the bottom of the tree pit. Of course, some of the water that has seeped into the planting soil layer inside the tree pit will also be absorbed by the plant roots.

[0038] Furthermore, the thickness of the colored asphalt concrete surface layer 5 in the tree pit is less than the thickness of the colored asphalt concrete permeable layer 6 in the tree pit, and the sum of the thicknesses of the colored asphalt concrete surface layer 5 and the colored asphalt concrete permeable layer 6 in the tree pit does not exceed half the vertical height of the metal baffle 1.

[0039] With the above setup, a tree pit structure that is both structurally strong and permeable can be constructed, allowing the planted plants to grow normally inside the tree pit, and the surface of the tree pit can also be used as a walkway.

[0040] Furthermore, the road structure is provided from top to bottom as follows: a colored asphalt concrete surface layer 9, a colored asphalt concrete permeable layer 10, and a colored asphalt concrete subbase layer 11. The outer connecting side plate 3 is connected between the colored asphalt concrete permeable layer 10 and the colored asphalt concrete subbase layer 11. In practice, it can also be connected within the colored asphalt concrete permeable layer 10 or the colored asphalt concrete subbase layer 11. The thickness of the colored asphalt concrete permeable layer 10 is not less than the thickness of the tree pit colored asphalt concrete permeable layer 6.

[0041] The concrete structure above the road surface and tree pit structure is basically the same. It is filled with permeable colored asphalt, so that the colored pattern of the asphalt road surface is continuous with the colored pattern on the upper surface of the tree pit, thereby improving the overall aesthetic effect.

[0042] One construction method for this colored asphalt concrete ecological tree pit includes the following steps: (1) Pre-embedding of permeable pipes: When excavating the pipeline under the garden road, pre-embedding a continuous permeable pipe along the location of the tree, and connecting the parallel permeable pipes with a T-junction, and finally connecting them to the municipal drainage pipe or water storage tank. (2) Tree pit enclosure construction: After the garden road is pre-embedded, the colored asphalt concrete sub-layer is leveled. The tree pit enclosure is placed on the colored asphalt concrete sub-layer according to the road paving elevation, ensuring that the upper edge of the metal baffle is flush with the road paving. (3) Asphalt pavement filling: After the tree pit enclosure is in place, the colored asphalt concrete permeable layer and the colored concrete surface layer of the pavement are laid in sequence according to the construction order. During the construction process, the asphalt concrete paving material ratio, porosity and compaction are consistent with the design requirements. The outer connecting side plate of the metal baffle is embedded in the asphalt concrete. (4) Tree excavation and planting: After the road surface is paved, the tree pit is excavated according to the planting season. After planting trees with soil balls are planted, planting soil (i.e., planting soil) is filled in, and after watering, the soil is allowed to settle for a period of time and then compacted. (5) Filling the inner surface of the tree pit: The colored asphalt concrete permeable layer and the colored asphalt concrete surface layer of the tree pit are laid in sequence according to the construction order. During the construction process, the asphalt concrete paving material ratio, porosity and compaction degree are consistent with the design requirements. (6) Color surface painting: Paint colored patterns on the road surface according to the design.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
