As shown in fig. 1 to 3, a root bottom drain apparatus includes a tree pit 1, a plurality of drain pipes 7 connected to a road bottom drain, and a transition device provided between the tree pit 1 and the drain; the transition device comprises a transition containing cavity 3, a buoy 4 arranged in the transition containing cavity 3, and the transition containing cavity 3 is communicated to the bottom of the tree pit 1; the shape and the size of the buoy 4 are matched with the transition accommodating cavity 3, a water retaining coaming is arranged at the bottom of the buoy 4, and the water retaining coaming respectively abuts against the two side walls of the transition accommodating cavity 3.

Compared with the prior art, in the prior art, the water collecting pipe 2 is arranged at the bottom of the reserved tree pit 1, and when rainwater or accumulated water in the soil of the tree pit 1 is excessive, the water permeates into the water collecting pipe 2 through the soil and is discharged into a drainage ditch at the bottom of a road through the accumulated water pipe. Can make the ponding of root department discharge rapidly, avoid dying because of the root soaks in ponding for a long time and rot, reduce the death rate of trees, save afforestation maintenance cost. However, the design mode has a single structure, and different living habits of different kinds of arbor after transplanting cannot be met through different arrangement. In the utility model, the provided drainage device is provided with the transition containing cavity 3 for transition, and the accumulated water in the water collecting pipe 2 is firstly discharged into the transition containing cavity 3, so that on one hand, for arbor with higher water repellency, such as ginkgo, the buoy 4 can be directly removed or the water retaining coaming is fixed by bolts, the drainage pipeline 7 at the lower part is exposed, and the drainage capacity is improved, so that the accumulated water in the transition containing cavity 3 can be directly discharged into a drainage ditch, and the water in the ginkgo tree pit 1 is effectively reduced. On the other hand, for the arbor with higher water-loving property, the accumulated water collected by the water collecting pipe 2 is preferentially discharged into the transition containing cavity 3, and in the initial stage, the water retaining coaming blocks the lower drainage pipeline 7, and only when the accumulated water in the transition containing cavity 3 is over the upper drainage pipeline 7 to a certain extent, the water is drained, and after the accumulated water is to a certain extent, the water discharging rate of the water collecting pipe 2 is reduced along with the increase of the water pressure in the containing cavity, so that the water in the tree pit 1 is ensured to be full. And when the water accumulation is reduced, the water retaining coaming falls down again due to dead weight and shields the drainage pipeline 7 below. The whole structure is more flexible and reliable.

The drainage pipeline 7 adopts PVC plastic pipes, and a plurality of drainage pipelines 7 are at least arranged in a plurality of rows and in a double-layer manner. The upper and lower double-layer drainage pipeline 7 automatically controls the opening and closing of the lower-layer drainage pipeline 7 when the water retaining coaming is driven to lift by the lifting of the buoy 4.

The water retaining coaming comprises a water retaining plate 6 close to one side of the drainage pipeline 7 and a filter screen plate 8 close to one side of the tree pit 1. The filter screen plate 8 near one side of the tree pit 1 shields impurities such as stone particles possibly brought from the water collecting pipe 2, and the later blockage is avoided.

The upper part of the water baffle 6 is provided with a strip-shaped empty groove 9, and the strip-shaped empty groove 9 is aligned to the upper drainage pipeline 7. The strip-shaped empty groove 9 is used for preventing the upper drainage pipeline 7 from being blocked in the process of driving the water baffle 6 to rise when the buoy 4 rises.

The lower part of the water baffle 6 is a solid plate and is blocked at the water inlet of the drainage pipeline 7 at the bottom layer. The solid part at the lower part of the water baffle 6 is used for shielding and opening the lower drainage pipeline 7 along with the lifting of the buoy 4.

The filter screen plate 8 is provided with a filter mesh screen.

In the actual use process, the two using modes are adopted when different trees are transplanted, after the trees with high water repellency are transplanted, the water drainage amount is increased, the buoy 4 is canceled or the water baffle 6 is fixed on the inner wall of the buffer containing cavity by using bolts, and the channel inlets of the upper layer of drainage pipeline 7 and the lower layer of drainage pipeline 7 are opened. Otherwise, the buoy 4 is enabled to work normally, and the lower layer drainage pipeline 7 is shielded by the solid part of the water baffle 6. In order to ensure that the shielding is in place, the water baffle 6 needs to be ensured to be directly upwards and downwards, and the water baffle 6 can be fixed by arranging a clamping groove on the inner wall of the buffer containing cavity. A bottom plate can be arranged at the lower part of the buoy 4, and the filter screen plate 8 and the water baffle 6 are respectively connected to the bottom plate to form a water baffle coaming, so that the stability of the framework is improved. The transplanting machine has various structural styles and high flexibility, and can make targeted adjustment for transplanting different trees.

The above embodiments are merely for illustrating the technical solution of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
