Description

Technical Field

[0001] This utility model relates to the field of municipal construction, and in particular to a tree drainage structure. Background Technology

[0002] Tree planting is an important part of urban greening, aiming to improve the urban environment, enhance the quality of life for residents, and promote ecological balance. However, many roads are now made of concrete. Planting trees on these roads often requires first creating designated trenches in the road, filling them with planting soil, and then allowing the trees to grow on the soil.

[0003] However, in actual tree planting, it was found that because concrete roads have poor drainage, if there is too much rain and it far exceeds the amount that trees can absorb, rainwater will accumulate in the trench and cannot be effectively drained. Excessive water can easily cause the roots of the planted trees to rot, affecting the growth of the trees, and in severe cases, it can even lead to the death of the trees. Utility Model Content

[0004] The purpose of this invention is to provide a tree drainage structure that can solve one or more of the above-mentioned problems.

[0005] According to one aspect of this utility model, a tree drainage structure is provided, comprising a backfill soil layer, a filter layer, a drainage layer, a drainage pipe, and an aeration rod.

[0006] A receiving groove is provided on the backfill soil layer, the bottom of the backfill soil layer is connected to the filter layer, and the bottom of the filter layer is connected to the drainage layer.

[0007] One end of the drainage pipe is embedded in the drainage layer, and the other end of the drainage pipe passes through the drainage layer, the filter layer, and the backfill soil layer in sequence before being exposed.

[0008] One end of the ventilator is embedded in the backfill soil layer, and the other end of the ventilator protrudes from the backfill soil layer.

[0009] The beneficial effects of this invention are as follows: The accommodating trough can accommodate tree roots for planting. When the backfill soil layer becomes excessively watery due to overwatering or rain, the excess water can pass through the filter layer into the drainage layer, preventing damage to the tree roots from excessive moisture and ensuring normal tree growth. When the drainage layer contains too much water, an external pump can remove the water through the drain pipe. The filter layer prevents debris from entering the drainage layer, ensuring its proper water storage and drainage. Furthermore, this invention includes a ventilation rod to facilitate air entry into the backfill soil layer, ensuring sufficient air for the tree roots to grow.

[0010] In some embodiments, the filter layer includes a grating and a first non-woven fabric, the first non-woven fabric covering the top of the grating and connected to the backfill layer. The first non-woven fabric facilitates the isolation of waste while allowing water to pass through, while the grating provides support and shaping to maintain the position of the first non-woven fabric, reducing the probability of displacement due to impacts from waste or water flow.

[0011] In some embodiments, the drainage layer is a gravel layer or a coarse sand layer. Both gravel layers and coarse sand layers have good water storage capacity.

[0012] In some embodiments, the ventilation rod comprises perlite and a second nonwoven fabric, the second nonwoven fabric being formed into a rod shape, and the rod-shaped second nonwoven fabric containing perlite. The second nonwoven fabric can reduce external contamination of the perlite, while both perlite and the second nonwoven fabric have good air permeability.

[0013] In some embodiments, the orifice diameter of the drain pipe is not less than 75 mm.

[0014] In some embodiments, the backfill layer has a sloping section on its side facing the centerline of the backfill layer, the sloping section extending to the filter layer and the drainage layer. The sloping section facilitates better flow of water from the backfill layer to the filter layer and from the filter layer to the drainage layer.

[0015] In some embodiments, the present invention further includes support strips, crossbars, and wire. Multiple support strips are present, with one end of adjacent support strips connected by a crossbar. The other end of each support strip is located around the perimeter of the backfill soil layer. The crossbars and support strips are connected by wire. The support strips are used to support trees to prevent them from falling over during initial planting, while the wire ensures an effective connection between the support strips and crossbars.

[0016] In some embodiments, the support strip is inclined to the horizontal plane, and the diameter of the support strip is 5-6 cm. This arrangement ensures the reliability of the support strip's support for the tree. Attached Figure Description
