Tree pool suitable for current tree root upheaval situation

Abstract

The utility model discloses a tree pool suitable for the current tree root upheaval situation, which comprises a sidewalk, a frame and wedge-shaped pieces, the frame is arranged on the sidewalk, the height of the frame is consistent with that of the sidewalk, planting soil is filled in the frame, and the wedge-shaped pieces are wedged into the planting soil at intervals. M10 cement mortar with the thickness of 20 mm is fixed on a concrete base with the section size of about 250 * 120 mm, a lower soil layer base is tamped (the tamping coefficient is not less than 0.90), a tree pool is filled by wedging small wedge-shaped dressed stones with the thickness of 80 * 80 * 200 mm into a planting soil layer (a coarse sand cushion layer with the thickness of 100 mm is added on the planting soil), the positions of tree roots are avoided, conventional seams with the thickness of 8 mm are reserved, and coarse sand is used for sweeping the seams, so that the situation that laying cannot be carried out due to the fact that the tree roots bulge is avoided, and the problem that the planting soil layer cannot be laid is solved.

Description

Technical Field

[0001] The utility model relates to the technical field of garden landscape, in particular to a tree pool suitable for the existing situation of raised tree roots. Background Art

[0002] At present, conventional tree pit filling methods include installing tree pit grates, laying small stones, and paving pebbles. However, for renovation projects, especially road sidewalks, it is often the case that the existing trees are large in size, the roots bulge during growth, and the impact range is large, resulting in damage to the tree pit filling. For such situations, there are the following common problems:

[0003] 1) Tree pool grates are difficult to lay;

[0004] 2) After paving the conventional 5cm thick small stones, they are easily lifted up by tree roots and easily loosened after being trampled for a long time, which will increase the subsequent maintenance cost;

[0005] 3) Scattered pebbles can be used; however, for narrow sidewalks, scattered pebbles provide a poor walking experience and it is difficult to achieve the need to widen the width of the passage by filling tree pits, and the minimum width requirement for road sidewalks is not met.

[0013] A wedge-shaped piece is wedged into the planting soil at intervals.

[0014] As a preferred solution of the tree pit suitable for the existing tree root bulge situation described in the utility model, the frame is made of non-polished granite, and cement mortar is arranged at the bottom of the frame.

[0015] As a preferred solution of the tree pit suitable for the existing tree root uplift situation described in the utility model, a concrete base is arranged at the bottom of the cement mortar, and a rammed earth layer is arranged at the bottom of the concrete base.

[0016] As a preferred solution of the tree pit suitable for the existing tree root uplift situation described in the utility model, seedlings are planted in the planting soil.

[0017] As a preferred solution of the tree pit suitable for the existing tree root uplift situation described in the utility model, a coarse sand cushion layer is filled between the wedge-shaped pieces, and an avoidance zone for avoiding the roots of saplings is provided between the wedge-shaped pieces.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the utility model is suitable for tree pits with existing tree root bulges. When laying, the paving will not be impossible due to the bulges of the tree roots. After the wedge-shaped small stones are installed, they are not easy to be lifted by the tree roots or loosened after long-term trampling. After laying, they are flat and firm, which can meet the needs of widening the passage width. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The utility model provides a tree pit suitable for the existing tree root bulge situation. When laying, it will not be impossible to lay due to the bulge of the tree roots. After the wedge-shaped small stones are installed, they are not easy to be lifted by the tree roots or loosened after long-term trampling. After laying, it is flat and firm, which can meet the needs of widening the passage width.

[0027] Figure 1-Figure 2 The structure diagram of a tree pit of the utility model applicable to the existing tree root uplift situation is shown. Figure 1-Figure 2 In this embodiment, a tree pit suitable for existing tree root uplift conditions is provided, and its main part includes a sidewalk 100, a frame 200 and a wedge 300.

[0028] Sidewalk 100;

[0029] The frame 200 is made of conventional granite and fixed on a concrete base 220 with a cross-sectional size of about 250*120mm using 20mm thick M10 cement mortar 210 (other specifications and sizes can be selected according to the actual situation of the construction site). The soil layer base thereunder should be compacted (the compaction coefficient is not less than 0.90). The length of the frame 200 can be appropriately adjusted according to the width of the on-site sidewalk 100 and the root range of the existing trees. The frame 200 is set on the sidewalk 100, and the frame 200 is at the same height as the sidewalk 100. The frame 200 is filled with planting soil 240. In this embodiment, the frame 200 is made of non-polished granite, and the bottom of the frame 200 is provided with cement mortar 210, and the bottom of the cement mortar 210 is provided with a concrete base 220, and the bottom of the concrete base 220 is provided with a rammed earth layer 230, and saplings 250 are planted in the planting soil 240.

[0030] The wedge 300 uses 80x80x200mm wedge-shaped small stones to wedge into the planting soil 240 (a 100mm thick coarse sand cushion layer 310 is added on the planting soil 240), avoiding the tree root position, and conventionally leaving a gap of 8mm. The laying of small stones should be trial-laid first, and the size details can be adjusted according to the on-site soil conditions to ensure that they can be smoothly wedged into the soil layer before purchasing and laying in large quantities. Specifically, the wedges 300 are wedged into the planting soil 240 at intervals. In this embodiment, the coarse sand cushion layer 310 is filled between the wedges 300, and an avoidance area 301 is provided between the wedges 300 to avoid the roots of the seedlings 250.

[0031] Combination Figure 1-Figure 2 The present embodiment is a tree pit suitable for the existing tree root bulge situation. The specific use process is as follows: the tree pit frame 200 is made of conventional granite whole stone, and is fixed on a concrete base 220 with a cross-sectional size of about 250*120mm using 20mm thick M10 cement mortar 210 (other specifications and sizes can be selected according to the actual situation of the construction site). The soil base below should be compacted (the compaction coefficient is not less than 0.90). The tree pit is filled with 80x80x200mm wedge-shaped small stones wedged into the planting soil 240 layer (a 100mm thick coarse sand cushion layer 310 is added to the planting soil 240), avoiding the tree root position, and conventionally leaving a gap of 8mm, and sweeping the gap with coarse sand. Therefore, when laying, it will not be impossible to lay due to the bulge of the tree roots. After the wedge-shaped small stones are installed, they are not easily lifted by the tree roots or loosened after long-term trampling. After laying, they are flat and firm, which can meet the needs of widening the passage width.

[0032] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
