[0035] As Figure 2 shown in the figure, the inner side of the telescopic pipe fitting 12 is provided with a first installation groove 122 with a "convex" cross-section, and a first straight profile 112 with a "convex" cross-section corresponding to two first plug-in grooves 121 is embedded on the two end faces on 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.

[0037] Implementation effect: During the process of the tree trunk diameter thickening and the root system development squeezing the telescopic frame 1 and the sealing plate assembly 3 of the tree pit, the telescopic frame 1 can be expanded outward, and the telescopic frame 1 can drive the sealing plate assembly 3 to expand outward. After being affected by the outward expansion force of the telescopic frame 1, the annular flexible compensation component 2 can deform, thus avoiding the occurrence of the tree pit arching.

[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 pipe fittings 12, so as to achieve the purpose that the telescopic frame 1 can expand outward during the process of being stressed inside. Most of the existing tree pits are square.

By having a first cavity 212 and a second cavity 213 in the cross-section of the first foam rubber strip 21, the deformation ability of the first foam rubber strip 21 during the stress process is improved. And an arc part 214 that extends obliquely downward in the direction away from the telescopic frame 1 is provided at the top of the cross-section of the first foam rubber strip 21. 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 part 214 extends obliquely upward 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 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 installation groove 122, and second sealing plates 32 are inserted at the connection between the end of each first installation groove 122 and the adjacent second installation groove 1131.
