Abstract
Description
Technical Field
[0001] This utility model provides a tree pit cover, and particularly relates to a permeable tree pit cover. Background Technology
[0002] Tree pit covers are covering devices installed around the roots of trees and inside the curb stones in urban roads or green belts. Their main function is to protect the soil around the tree roots from compaction caused by pedestrians and vehicles, while providing infiltration channels for rainwater and irrigation water to ensure the growth needs of trees. In addition, they also beautify the environment, prevent soil from overflowing from the tree pit, and reduce garbage entering the tree pit. They are an important part of urban greening and municipal facilities.
[0003] Existing tree pit covers are typically single-plate structures with several permeable holes and a central clearance hole for trees to pass through. They are laid directly on the soil surface beneath the tree or within the tree pit enclosed by curb stones. However, this type of structure has significant drawbacks: First, the permeable holes are directly connected to the soil below or drainage pipes, allowing rainwater to carry debris such as fallen leaves, silt, and gravel into the drainage system or deposit on the soil surface, easily causing blockages. Cleaning also requires completely removing the cover and reaching deep into the tree pit, a cumbersome and difficult process. Second, the cover lacks a dedicated support and fixing structure, making it prone to displacement or loosening under external forces when laid inside the curb, affecting overall stability. Third, the clearance holes are poorly adapted to the tree's diameter, failing to accommodate changes in tree diameter during growth. This can lead to gaps that are too large, allowing debris to fall in, or a tight fit that hinders tree growth. Utility Model Content
[0004] The present invention aims to provide a permeable tree pit cover with good water permeability, easy cleaning of debris, stable structure and good adaptability to trees, so as to solve the shortcomings of existing tree pit covers.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a permeable tree pit cover, comprising a square cover plate with multiple elongated permeable holes spaced apart along the length and width of the cover plate, and a clearance hole for avoiding trees in the middle of the cover plate; it also includes a receiving cavity disposed below the cover plate, the receiving cavity being a box-shaped structure with an open top, and the opening of the receiving cavity being adapted to the cover plate to receive the cover plate; at least four support members are disposed around the periphery of the receiving cavity, each of the support members being spaced apart along the periphery of the receiving cavity and used to support the receiving cavity and the cover plate; a permeable structure is provided at the bottom of the receiving cavity, and the receiving cavity forms a cavity for temporarily storing debris during the permeation process, so as to facilitate the cleaning of debris.
[0006] Furthermore, the cover plate is a rectangular plate, and the length direction of each of the elongated water-permeable holes is parallel to the length direction or width direction of the cover plate, and the elongated water-permeable holes are evenly distributed along the surface of the cover plate.
[0007] Furthermore, the clearance hole is a circular hole, and a buffer pad for adapting to the surface of the tree is provided on the hole wall.
[0008] Furthermore, the receiving cavity includes a rectangular surrounding plate and a bottom plate disposed at the bottom of the surrounding plate. The surrounding plate and the bottom plate enclose the cavity with an opening at the top. The water-permeable structure consists of a plurality of water-permeable holes formed on the bottom plate.
[0009] Furthermore, the bottom plate has a connection hole in the middle that is compatible with the drainage pipe below, and a connecting pipe for connecting with the drainage pipe is connected to the connection hole.
[0010] Furthermore, the support member is a long strip-shaped support block, the length direction of the support block is parallel to the side length direction of the receiving cavity, and at least four of the support blocks are respectively supported on the four outer corners of the receiving cavity.
[0011] Furthermore, a plurality of reinforcing ribs are provided on the inner wall of the receiving cavity, and each reinforcing rib extends along the height direction of the receiving cavity and is distributed at intervals along the circumference of the receiving cavity.
[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages compared with the prior art:
[0013] This permeable tree pit cover uses a square cover with elongated permeable holes and clearance holes to ensure water permeability and adaptability to trees. The box-shaped cavity below the cover can temporarily store permeable debris, preventing blockage of the drainage system and facilitating centralized cleaning. The permeable structure at the bottom of the cavity allows water to pass through normally while debris is stored. The supporting components around the cavity enhance the installation stability of the cover and cavity, making the structure more securely installed at the tree base within the curb. The reinforcing ribs on the inner sidewall of the cavity enhance its structural strength, and the connecting hole in the middle of the bottom plate cooperates with the connecting pipe to better connect to the drainage pipe, further optimizing water permeability and the convenience of debris cleaning. Overall, it improves the water permeability, debris management efficiency, structural stability, and durability of the tree pit area.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0023] like Figure 1 and Figure 2 As shown, a permeable tree pit cover includes a square cover plate 1. The cover plate 1 has multiple elongated permeable holes 2 spaced apart along its length and width. The cover plate 1 also has a clearance hole 3 in the middle for avoiding trees. The clearance hole 3 is a circular hole with a buffer pad on its wall to fit the surface of the tree. The cover plate 1 also includes a receiving cavity 4 located below the cover plate 1. The receiving cavity 4 is a box-shaped structure with an open top, and the opening is adapted to the cover plate 1 to receive the cover plate 1. At least four support members 5 are provided around the periphery of the receiving cavity 4. Each support member 5 is an elongated support block. The length direction of the support block is parallel to the side length direction of the receiving cavity 4, and at least four support blocks are respectively supported on the four outer corners of the receiving cavity 4 to support the receiving cavity 4 and the cover plate 1.
[0024] In this implementation scheme, a square cover plate 1 and a box-shaped receiving cavity 4 with an open top are fitted together to achieve a closed fit. Four elongated support blocks 5 are distributed along the four outer corners of the receiving cavity 4, providing stable support for the receiving cavity 4 and the cover plate 1 above. The elongated permeable holes 2 on the cover plate 1 are spaced apart along the length and width of the plate. The wall of the circular avoidance hole 3 in the middle fits tightly with the buffer pad. From the perspective of implementation points and innovation, the beneficial effects of the combination of components are significant: the elongated permeable holes 2 ensure efficient infiltration of rainwater and irrigation water while initially intercepting fallen leaves and larger particles of debris, preventing them from directly entering the structure below; the circular avoidance hole 3, in conjunction with the buffer pad, provides ample avoidance space for tree growth and adapts to the growth of tree diameter, preventing debris from falling into the gap between the tree and the hole wall, while avoiding hard contact that could damage the tree bark, effectively solving the problem of poor adaptability of existing cover plates to trees. The support blocks 5 on the four outer corners provide multi-point symmetrical support, making it less likely for the receiving cavity 4 and the cover plate 1 to shift or loosen after installation in the tree base part inside the curbstone. This improves the overall structural stability and addresses the shortcomings of existing cover plates that lack effective support and are prone to swaying. The fitting of the cover plate 1 with the receiving cavity 4 provides a basic carrier for the temporary storage of debris. The coordinated action of each structure achieves the core permeable function while also taking into account tree protection and structural stability, laying the foundation for solving the key problems of existing tree pit cover plates.
[0025] like Figure 2 and Figure 3 As shown, the receiving cavity 4 of a permeable tree pit cover includes a rectangular surrounding plate and a bottom plate disposed at the bottom of the surrounding plate. The surrounding plate and the bottom plate enclose a cavity with an open top. The permeable structure at the bottom of the receiving cavity 4 consists of multiple permeable holes opened on the bottom plate. A connection hole adapted to the drainage pipe below is opened in the middle of the bottom plate. A connecting pipe for connecting with the drainage pipe is connected to the connection hole. Multiple reinforcing ribs are also provided on the inner side wall of the receiving cavity 4. Each reinforcing rib extends along the height direction of the receiving cavity 4 and is distributed at intervals along the circumference of the receiving cavity 4.
[0026] In this implementation scheme, the rectangular enclosure of the receiving cavity 4 is connected to the bottom plate to form a cavity with an open top. Multiple permeable holes on the bottom plate are evenly distributed to form a permeable structure. A connecting hole in the middle of the bottom plate is fixedly connected to a connecting pipe, which extends downwards to connect with the drainage pipe below. Each reinforcing rib on the inner wall of the receiving cavity 4 is connected at one end to the top of the enclosure and extends to the bottom plate at the other end, and is arranged at intervals along the circumference of the receiving cavity 4. From the perspective of implementation points and innovation, the beneficial effects of each structural combination are prominent: the cavity enclosed by the enclosure and bottom plate serves as a core area for temporary storage of debris, capable of receiving debris falling from the permeable holes of the cover plate, preventing debris from directly entering the drainage pipe or deep soil and causing blockages. This solves the pain point of difficult debris cleaning of existing cover plates; during cleaning, only the cover plate needs to be lifted for centralized treatment of debris in the cavity. The permeable holes on the bottom plate, while allowing rainwater and irrigation water to infiltrate and discharge, can further trap fine silt and other debris, ensuring the continuity of permeability and the smooth flow of the drainage system. The connecting hole in the middle of the bottom plate... The pipe connects with the drainage pipe, creating a more direct and efficient drainage path, accelerating the drainage of accumulated water, and preventing water accumulation in the tree pit from affecting the growth of tree roots. The reinforcing ribs on the inner wall extend along the height direction, effectively dispersing the vertical pressure and lateral force on the receiving cavity 4, preventing deformation of the enclosure due to the weight of accumulated debris or external forces during long-term use, and extending the service life of the receiving cavity 4. The coordinated action of each structure not only improves the efficiency of debris management and drainage, but also strengthens the structural stability of the receiving cavity 4 itself, making up for the shortcomings of existing tree pit covers that lack a debris storage structure and optimized drainage design.
[0027] Before installing the permeable tree pit cover, clean the area around the tree roots enclosed by the curb, removing gravel, weeds, and other debris. Then, pour a uniformly thick concrete foundation at the bottom of the tree pit according to the dimensions of the cavity, and level it using a spirit level to ensure the foundation surface is flat and maintains a suitable distance from the inner wall of the curb. Next, place the supports in the pre-set positions on the concrete foundation, and gently tap them with a rubber mallet to adjust their positions so that the tops of all supports are on the same level. Then, hoist the cavity above the supports and slowly lower it, ensuring the bottom of the cavity is in close contact with the supports. Align the connecting pipe at the bottom of the cavity with the municipal drainage pipe pre-laid under the tree pit, and seal the joint between the connecting pipe and the drainage pipe with sealant to prevent leakage. Finally, install the cover. Slowly slide the cover plate over the tree from above, allowing it to pass through the clearance hole and adjust its position so that the bottom of the cover plate is completely flush with the top opening of the receiving cavity. Finally, gently press the cover plate to ensure it is firmly in place. During daily use, when rainwater or irrigation water enters the tree pit, it flows into the cavity through the permeable holes on the cover plate. After the water drains into the drainage pipe through the permeable holes and connecting pipe, periodically use tools to lift the cover plate and use a broom to sweep and collect the temporarily stored debris in the cavity and transport it to the municipal garbage bin. After cleaning the debris, replace the cover plate on the receiving cavity. The entire process, including concrete foundation pouring, leveling with a level, sealing with sealant, and hoisting and positioning, all adopt conventional technical methods and operating procedures in existing municipal greening construction, forming a complete tree pit cover plate installation and usage solution in conjunction with the structure of this device.
[0028] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
