Description

Technical Field

[0001] This utility model relates to the field of environmental greening, and in particular to a spherical greening structure based on earth mounds. Background Technology

[0002] In park landscaping, spherical greening structures are commonly seen, formed by planting shrubs in the soil within the spherical structure. Patent number CN202022686469.9 discloses a shrub-grass ecological spherical restoration structure, which uses a layered first shell, second shell, and third shell to cover different soil layers and shrub seeds. The growth of the shrub seeds binds the different soil layers together, ultimately forming the entire spherical greening structure. However, this spherical greening structure requires a long period of growth for the shrub seeds to achieve structural stability between the soil layers, resulting in low production efficiency. It cannot meet the rapid construction requirements of environmental greening operations and is unsuitable for environmental greening operations with short time constraints. Therefore, it is necessary to improve this structure. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a spherical greening structure based on earthwork that is structurally stable and allows for rapid construction.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A spherical greening structure based on soil mounds includes a fixed sphere, on the outer surface of which a grid is fixedly installed and covers the outer perimeter of the sphere. The grid and the outer surface of the fixed sphere are combined to form several rectangular cavities with external openings. Soil mounds are embedded in the rectangular cavities. A bottom positioning component and a side positioning component are provided in the rectangular cavities. One end of the bottom positioning component is connected to the outer surface of the fixed sphere, and the other end of the bottom positioning component is inserted into the soil mound. One end of the side positioning component is connected to the grid, and the other end of the side positioning component is inserted into the soil mound.

[0005] Furthermore, the grid member is composed of a number of transverse grid plates and a number of longitudinal grid plates. The transverse grid plates are all annular and are evenly spaced around the outer surface of the fixed sphere along the longitudinal direction of the fixed sphere. The longitudinal grid plates are all annular and are evenly spaced around the outer surface of the fixed sphere along the transverse direction of the fixed sphere. The transverse grid plates and longitudinal grid plates are perpendicularly connected to each other to form a rectangular frame structure for supporting the piled soil. The rectangular frame structure is combined with the outer surface of the fixed sphere to form a number of rectangular cavities with external openings.

[0006] Furthermore, the grid element is integrally formed or fixedly welded to the fixed sphere.

[0007] Furthermore, the bottom positioning component includes a positioning post, which is cylindrical. One end of the positioning post is fixedly connected to the outer surface of the fixed sphere, and the other end of the positioning post faces the opening direction of the rectangular cavity and is pointed. Several receiving grooves are evenly spaced on the circumferential sidewall of the positioning post. The length direction of the receiving groove is consistent with the length direction of the positioning post. An elastic rod is provided at one end of the receiving groove near the opening direction of the rectangular cavity. One end of the elastic rod is integrally formed with the positioning post, and the other end of the elastic rod tilts outward and extends to the outside of the receiving groove under the elastic action.

[0008] Furthermore, the length of the elastic rod is less than the length of the receiving groove, and the inner wall of the end of the elastic rod away from the positioning post is set as a beveled notch structure so that when the elastic rod is squeezed into the receiving groove, a feeding gap is formed between the end of the elastic rod away from the positioning post and the inner end wall of the receiving groove.

[0009] Furthermore, the side positioning component includes a positioning sleeve and a positioning pin. One end of the positioning sleeve is an open end and is detachably connected to the transverse grid plate. The other end of the positioning sleeve extends into the rectangular cavity and is sealed with a sharp point. Several through holes are evenly spaced on the circumferential sidewall of the positioning sleeve. The length direction of the through holes is consistent with the length direction of the positioning sleeve. A locking rod is provided in the through hole near the sealed end of the positioning sleeve. The locking rod is located in the through hole and one end of the locking rod is integrally formed with the positioning sleeve. A wedge block is provided on the inner wall of the locking rod. The wedge block is inclined and thicker on the side near the sealed end of the positioning sleeve and thinner on the side away from the sealed end of the positioning sleeve. The positioning pin is inserted into the positioning sleeve and, under the action of the wedge block, squeezes one end of the locking rod to the outside of the through hole.

[0010] Furthermore, the transverse grid plate is provided with a mounting through hole, which is located on one side of the rectangular cavity; the outer side of the opening end of the positioning sleeve is integrally formed with a limiting protrusion, the positioning sleeve is embedded in the mounting through hole and the end face of the limiting protrusion is in contact with the end face of the transverse grid plate.

[0011] Furthermore, the outer diameter of the positioning pin is adapted to the inner diameter of the positioning sleeve, and the positioning pin is engaged or threaded with the positioning sleeve.

Detailed Implementation

[0017] 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, any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art to all other embodiments obtained without creative effort should be included within the protection scope of the present utility model.

[0018] like Figures 1 to 8 As shown, this embodiment discloses a spherical greening structure based on soil mounds. The spherical greening structure includes a fixed sphere 1, which is a hollow plastic sphere structure. A grid 2 is integrally formed on the outer surface of the fixed sphere 1 and the grid 2 covers the outer peripheral sidewall of the fixed sphere 1. After the grid 2 is combined with the outer surface of the fixed sphere 1, it forms a number of rectangular cavities 23 with external openings. The grid member 2 is composed of a number of transverse grid plates 21 and a number of longitudinal grid plates 22. The transverse grid plates 21 are all annular plates and are evenly spaced around the outer surface of the fixed sphere 1 along the longitudinal direction of the fixed sphere. The longitudinal grid plates 22 are all annular plates and are evenly spaced around the outer surface of the fixed sphere 1 along the transverse direction of the fixed sphere 1. The transverse grid plates 21 and the longitudinal grid plates 22 are perpendicularly connected to each other to form a rectangular frame structure for supporting the soil blocks 3. The rectangular frame structure is combined with the outer surface of the fixed sphere 1 to form a number of rectangular cavities 23 with external openings.

[0019] The rectangular cavity 23 is fitted with a soil block 3; the rectangular cavity 23 is provided with a bottom positioning component 5 and a side positioning component 6. One end of the bottom positioning component 5 is connected to the outer surface of the fixed sphere 1, and the other end of the bottom positioning component 5 is inserted into the soil block 3; one end of the side positioning component 6 is connected to the grid component 2, and the other end of the side positioning component 6 is inserted into the soil block 3.

[0020] Soil blocks are plastic fiber cultivation soil blocks, whose main components are agricultural waste such as straw and cotton stalks. Soil blocks are characterized by solidification and plasticity, lightweight, air permeability, moisture retention, and drainage. They resemble sponge-like planting bricks in appearance and can be applied to a variety of complex environments. When using them, it is usually necessary to cut the monolithic soil blocks into blocks according to shape and size requirements to meet the needs of different environmental scenarios.

[0021] In the design, the width of the horizontal and vertical grid plates can be selected according to the thickness of the soil blocks. The thickness of the soil blocks needs to be greater than the width of the horizontal and vertical grid plates. The multiple rectangular cavities formed by the cross combination of the horizontal and vertical grid plates should keep their inner diameters as similar as possible so as to fit the soil blocks with matching inner diameters.

[0022] like Figure 4 , Figure 5 , Figure 6 As shown, the bottom positioning component 5 includes a positioning post 51, which is cylindrical. One end of the positioning post 51 is fixedly connected to the outer surface of the fixed sphere 1, and the other end of the positioning post 51 faces the opening direction of the rectangular cavity 23 and is sharp. Several receiving grooves 511 are evenly spaced along the circumferential direction on the circumferential sidewall of the positioning post 51. The length direction of the receiving grooves 511 is consistent with the length direction of the positioning post 51. An elastic rod 512 is provided at one end of the receiving groove 511 near the opening direction of the rectangular cavity 23. One end of the elastic rod 512 is integrally formed with the positioning post 51, and the other end of the elastic rod 512 tilts outward and extends to the outside of the receiving groove 511 under the elastic action.

[0023] The length of the elastic rod 512 is less than the length of the receiving groove 511. The inner wall of the end of the elastic rod 512 away from the positioning post 51 is set as a beveled notch structure so that when the elastic rod 512 is squeezed into the receiving groove 511, a feeding gap 513 is formed between the end of the elastic rod 512 away from the positioning post 51 and the inner end wall of the receiving groove 511.

[0024] In its normal state, the elastic rod will be tilted and extend outside the receiving groove, such as... Figure 4 As shown; when the earthen block is embedded into the rectangular cavity, the top of the positioning post will insert into the earthen block. Simultaneously, the elastic rod will enter the receiving groove under the squeezing action of the earthen block, facilitating the rapid insertion of the positioning post into the earthen block as a whole. Figure 5 As shown, when the soil block detaches from the rectangular cavity, some soil debris will enter between the elastic rod and the receiving groove through the feeding gap, thereby pushing the elastic rod out of the receiving groove. The elastic rod is in an open state, which will block the detachment action of the soil block, so as to achieve the technical effect of preventing the soil block from detaching from the rectangular cavity, effectively ensuring the stability of the installation structure of the soil block in the rectangular cavity.

[0025] like Figure 7 , Figure 8As shown, the side positioning component 6 includes a positioning sleeve 61 and a positioning pin 62. The transverse grid plate 21 has a mounting through hole 211 located on the upper side of the rectangular cavity 23. One end of the positioning sleeve 61 is open, and a limiting protrusion 614 is integrally formed on the outer side of the open end. The positioning sleeve 61 is embedded in the mounting through hole 211, and the end face of the limiting protrusion 614 contacts the end face of the transverse grid plate 21. The other end of the positioning sleeve 61 extends into the rectangular cavity 23, and is sealed and pointed. A plurality of through holes 611 are evenly spaced along the circumferential direction on the circumferential sidewall of the positioning sleeve 61. The length direction of the through holes 611 is perpendicular to the positioning pin. The sleeves 61 are aligned along their length. A locking rod 612 is provided inside the through hole 611 on one side near the sealing end of the positioning sleeve 61. The locking rod 612 is located inside the through hole 611, and one end of the locking rod 612 is integrally formed with the positioning sleeve 61. A wedge block 613 is provided on the inner wall of the locking rod 612. The wedge block 613 is inclined, thicker on the side near the sealing end of the positioning sleeve 61 and thinner on the side away from the sealing end of the positioning sleeve 61. The outer diameter of the positioning pin 62 is adapted to the inner diameter of the positioning sleeve 61. The positioning pin 62 is inserted into the positioning sleeve 61, and under the action of the wedge block 613, one end of the locking rod 612 is pressed to the outside of the through hole 611. The positioning pin 62 is threadedly connected to the positioning sleeve 61.

[0026] When embedding the soil blocks into the rectangular cavity, each layer of the rectangular cavity needs to be embedded sequentially from bottom to top along the fixed sphere. During embedding, first embed the soil block into the rectangular cavity, inserting the bottom positioning component into the soil block. Then, insert the positioning sleeve into the mounting through hole on the upper side of the rectangular cavity. After passing through the mounting through hole, the positioning sleeve is inserted into the soil block from one side. During insertion, the locking rod is located in the through hole and will not obstruct the insertion of the positioning sleeve. Figure 8 As shown; after the positioning sleeve is inserted, the positioning pin is inserted into the positioning sleeve. As the positioning pin is inserted, the side wall of the positioning pin will squeeze the inclined surface of the wedge block, and under the squeezing action, one end of the locking rod will extend to the outside of the through hole, thereby achieving further locking and limiting of the soil block (as shown). Figure 7 As shown), this prevents the soil blocks from detaching from the rectangular cavity, further improving the stability of the installation structure of the soil blocks inside the rectangular cavity. After embedding the soil blocks into the rectangular cavity of this layer and installing the side wall positioning components, the same steps are repeated for embedding soil blocks into the rectangular cavity of the upper layer. For the rectangular cavity at the top of the fixed sphere, it is not necessary to set the side wall positioning components. The soil blocks can be directly embedded into the rectangular cavity and inserted into the bottom positioning components.

[0027] The bottom positioning component and the side positioning component can effectively realize the installation and positioning of the soil blocks in the rectangular cavity, ensuring a stable connection between the soil blocks and the entire fixed sphere. The soil blocks can also be stably embedded in the rectangular cavity at the bottom of the fixed sphere, preventing the soil blocks from detaching from the rectangular cavity under gravity. This improves the construction and assembly efficiency of the entire spherical greening structure and its structural stability.

[0028] The end of the elastic rod 512 away from the positioning post 51 is configured with a serrated structure along the width direction of the elastic rod 512; the end of the locking rod 612 away from the positioning sleeve 61 is configured with a serrated structure along the width direction of the locking rod 612.

[0029] The soil structure of the mound contains strips and filaments such as plant roots and straw fragments. By setting a serrated structure at one end of the elastic rod and the locking rod, the contact area and the obstructed area with the plant roots and straw fragments can be increased. When the serrated structure comes into contact with the plant roots and straw fragments, it will cause obstruction and locking phenomena, which improves the connection effect between the elastic rod, the locking rod and the mound, thereby improving the obstruction effect of the elastic rod and the locking rod on the mound and preventing the mound from detaching from the rectangular cavity. This further improves the insertion and positioning effect of the bottom positioning component and the side positioning component on the mound.

[0030] The bottom of the fixed sphere 1 is fixedly connected to a load-bearing column 4 and fixed to the ground by the load-bearing column 4. When the spherical greening structure is installed, it is supported by the load-bearing column 4. The top of the load-bearing column 4 is installed in the rectangular cavity at the bottom of the fixed sphere 1, which will not affect the soil blocks in other rectangular cavities.

[0031] This invention employs a design that uses grating components on a fixed sphere to form a rectangular cavity. This allows for direct embedding of rectangular soil blocks into the rectangular cavity during spherical greening structure construction. Finally, shrubs and grasses are planted within the soil blocks. Furthermore, bottom and side positioning components define the position of the embedded soil blocks at their bottom and sidewalls, preventing them from detaching from the rectangular cavity and effectively ensuring the structural stability of the entire spherical greening structure. This structure significantly improves construction efficiency, meeting the rapid construction needs of environmental greening operations. It can be used in environmental greening projects with short time requirements, expanding the applicability of spherical greening structures and bringing convenience to environmental greening work.
