Description

Technical Field

[0001] This invention relates to the field of urban landscaping construction, and in particular to a combined and assembled root-controlling planting pool for tall trees on sidewalks in northern cities. Background Technology

[0002] In garden pedestrian walkways, tall trees typically have extensive root systems. Their taproots and numerous lateral roots intertwine and become intricate. As the trees grow, these root systems expand throughout the soil, causing significant damage to hardscape elements such as stone or brick paving. A common phenomenon is that the immense force generated by the root growth causes the ground to bulge and deform, forming uneven ridges. This not only affects pedestrian safety but also severely detracts from the overall aesthetics and smoothness of the landscape.

[0003] Currently, the common approach to addressing this issue is to excavate the damaged area of ​​the paving and manually trim the roots that extend beyond the designated area after the damage is discovered. However, this method has significant drawbacks: firstly, frequent excavation of the paving layer increases construction costs and maintenance workload; secondly, excessive pruning of the tree roots can damage the trees' health, affecting their growth stability and lifespan, and may even lead to weakened growth and reduced resistance to pests and diseases, failing to fundamentally solve the potential for root damage to the paving. Summary of the Invention

[0004] The purpose of this invention is to provide a modular root-control planting pool for tall trees on sidewalks in northern cities in order to solve the above-mentioned problems. This solves the problem of the roots of tall trees damaging the sidewalk pavement, while avoiding irreversible damage to plant growth.

[0028] The construction method of the present invention includes the following steps:

[0029] S1. Material preparation: Based on the specific species of tree, expected growth status and pre-designed size of the planting pond, customize root control blankets and hollow edge stones of appropriate length and roll up the root control blankets and put them inside the hollow edge stones for later use.

[0030] S2. Site construction: At the beginning of construction, precise measuring tools are used to locate the planting pits. The depth and diameter of the planting pits are scientifically determined based on the growth characteristics of the tree roots and the actual soil conditions to ensure that sufficient growth space is reserved for the roots and that there will be no adverse impact on the surrounding facilities. The sidewalk base is leveled and compacted to ensure the stability of the base and lay a good foundation for the subsequent installation of the equipment.

[0031] S3. Installation: According to the design plan, accurately install the hollow edging stone inside the planting hole. Use measuring tools to ensure that its verticality and horizontality meet the requirements. Use concrete or other suitable fixing materials to stabilize the hollow edging stone. Then, carefully pull out the root control blanket from the groove at the bottom of the hollow edging stone. According to the shape and size of the planting hole, evenly lay the root control blanket on the bottom and around the planting hole, ensuring that the root control blanket is in close contact with the soil and without wrinkles or damage, and ensuring that its laying range can completely cover the main growth area of ​​the tree root system.

[0032] S4. Seedling Planting: After the root control blanket is laid, the selected tall tree seedlings are planted in the center of the planting hole according to the conventional planting process. The seedlings are straightened and then the soil is filled in. During the filling process, special attention is paid to protecting the root control blanket and the root system of the seedlings. The soil is filled in layers and compacted appropriately to ensure that the soil and the root system are closely connected, creating an excellent soil environment for the growth of the seedlings.

[0033] The invention is used as follows: It features a reasonable and simple structure, low production cost, and convenient installation. Before construction, materials are prepared, and suitable root control mats 5 and hollow curb stones (including hollow curb stone one 4, hollow curb stone two 6, and hollow curb stone three 7) are customized according to actual needs. The root control mat 5 is then properly placed inside the hollow curb stone. After site construction, planting holes 12 are excavated after precise measurement and positioning, determining the appropriate depth and diameter. The surrounding sidewalk base layer is then treated. After treatment, the mats are assembled. First, multiple hollow curb stones three 7 are assembled around the bottom of the planting hole 12, and then connected using concrete or other methods. Suitable fixing materials are used to stabilize multiple hollow edging stones 3 7. Then, root control mat 5 is carefully pulled out from the groove 45 of the hollow edging stone and laid. Subsequently, soil layer 8 is filled into the space enclosed by these hollow edging stones 3 7. Then, hollow edging stones 2 6 are fixed on top of the hollow edging stones 3 7. The outer side of hollow edging stone 2 6 is tightly connected to the inner wall of the planting hole 12, and the space it encloses provides a space for soil layer 2 9. Similarly, hollow edging stone 4 is installed in the opposite direction on top of hollow edging stone 2 6 and fixed to the inner wall of the planting hole 12, also enclosing the space of soil layer 2 9. Then, the root control mat 5 in hollow edging stone 4 is placed inside. The root control blanket 5 is pulled out and laid around the planting hole 12 on the sidewalk base layer, followed by the laying of paving bricks 3. Another part of the root control blanket 5 extends to the bottom of paving bricks 3, soil layer 8, and soil layer 9, playing a role in root control. The tensile fiber mesh 51 (polyester fiber material) on its surface effectively protects the internal structure, while the one-way permeable membrane 52 (nanoporous material) in the middle guides nutrients to permeate downwards in one direction. The coarse fiber geotextile 53 (polypropylene material) at the bottom ensures long-term stability in the soil. Finally, the bottom of the U-shaped seat 1 is firmly connected to the top of the hollow vertical edge stone 4, and the locking groove 2 on the inner side of its bottom is tightly connected to the upper inner side of the hollow vertical edge stone 4, enhancing the root control function. The overall structure is stable. The landscape texture or decorative lines on the outer side of the U-shaped base 1 add beauty to the surrounding environment. The U-shaped base pad 10 (made of wood) is fixed to the top surface of the U-shaped base 1 by several fixing screws 11, providing a comfortable walking surface for pedestrians and also playing a certain protective role for the device. After the splicing and assembly is completed, the seedlings are planted. The tall tree seedlings are inserted into the center of the planting hole 12 and the soil layer 2 9 is filled. When filling the soil, the root control blanket 5 and the root system of the seedlings are protected to ensure that the whole device is in good working condition, effectively controlling the growth of tree roots, while protecting the sidewalk pavement and promoting the healthy growth of seedlings.
