[0002] The main purpose of a tree pit is to protect and promote the growth of plants while beautifying the environment. A tree pit is a piece of unpaved land reserved around a tree when it is planted. It provides the necessary growth environment for the roots of the tree, including soil, water and air circulation, thereby promoting the healthy growth of the tree.

[0003] As trees grow year by year, their diameters become thicker and their root systems develop, squeezing the surrounding tree holes, causing the tree holes to bulge. This not only affects the normal growth of trees and the road landscape, but also brings many safety hazards to citizens' travel. Summary of the invention

At the same time, the cross-section of the first foam strip 21 has a first cavity 212 and a second cavity 213 located below the first cavity 212. The top of the cross-section of the first foam strip 21 is provided with an arc portion 214 extending downwardly and obliquely in a direction away from the telescopic frame 1, and the upper end of the arc portion 214 extends upwardly and obliquely in a direction close to the telescopic frame 1.

[0035] like Figure 2 As shown, a first mounting groove 122 with a convex cross-section is provided on the inner side of the telescopic tube 12, and a first straight profile 112 with a convex cross-section and second plug-in grooves 1121 corresponding to the two first plug-in grooves 121 are respectively embedded on the two end surfaces of the outer side of the corner connector 11; the sealing plate assembly 3 includes a plurality of first sealing plates 31 and a plurality of second sealing plates 32, a plurality of first sealing plates 31 are inserted in the middle of each first mounting groove 122, a second sealing plate 32 is inserted in the connection between the end of each first mounting groove 122 and the adjacent second mounting groove 1131, and the two second sealing plates 32 close to the same corner connector 11 are in conflict with each other in the initial state.

[0037] Implementation effect: When the tree diameter becomes thicker and the root system develops to squeeze the tree hole, the retractable frame 1 and the sealing plate assembly 3 can be expanded outward, and the retractable frame 1 can drive the sealing plate assembly 3 to expand outward. The annular flexible compensation assembly 2 can be deformed after being subjected to the outward expansion force of the retractable frame 1, thereby avoiding the occurrence of arching of the tree hole.

[0038] In the structure of the telescopic frame 1, a polygonal telescopic structure is formed by a plurality of corner connectors 11 and a plurality of telescopic pipes 12, so that the telescopic frame 1 can be expanded outwards during the inner force process. Most existing tree holes are square, and at this time, four corner connectors 11 and four telescopic pipes 12 are provided to form a square frame, which is more in line with the shape of the existing tree holes, and linear plug-in parts 111 for telescopic insertion in the telescopic pipes 12 are provided at both ends of the corner connectors 11, so that the telescopic frame 1 can maintain a connection state during the inner and outer expansion process.

Since the soil layer will cover the first foam rubber strip 21 after installation, the deformation resistance of the first foam rubber strip 21 when being squeezed can be reduced; at the same time, the upper end of the arc portion 214 extends upwardly and obliquely in the direction close to the telescopic frame 1, so that when installed on the telescopic frame 1, it can be tightly pressed against the outside of the telescopic frame 1 through deformation. The sealing plate assembly 3 includes multiple first sealing plates 31 and multiple second sealing plates 32. Multiple first sealing plates 31 are inserted in the middle of each first mounting groove 122, and a second sealing plate 32 is inserted in the connection between the end of each first mounting groove 122 and the adjacent second mounting groove 1131.

[0043] Implementation effect: When the outer side of the corner connector 11 is arc-shaped, a third plug-in groove 123 with a "convex"-shaped cross-section is provided on the outer side of the telescopic tube 12, and a first arc-shaped profile 114 with a fourth plug-in groove 1141 with a "convex"-shaped cross-section and corresponding to the two third plug-in grooves 123 is provided at the corresponding position of the outer side of the corner connector 11.
