Description

Technical Field

[0001] The invention relates to the technical field of landscape greening, and in particular to a structure for drainage and water collection and reuse applied to landscape greening tree pools. Background Art

[0002] In landscape design, tree pools are important greening elements that not only add greenery to the landscape, but also provide practical functions such as sunshade. However, the drainage problem of tree pools is often overlooked, resulting in frequent problems such as restricted tree growth and soil salinization.

[0003] As we all know, trees need a good soil environment to grow. However, if the soil is not well drained, it will cause the soil to be too wet, affecting the root respiration and nutrient absorption of the trees. At the same time, poor soil drainage will also cause the salt in the soil to rise with the water, which will cause soil salinization. Salinized soil will inhibit the growth of trees and even cause the death of trees. Therefore, the drainage system of the tree pool is crucial to ensure the growth of trees. Summary of the invention

[0019] In one embodiment, Figure 1-2 As shown, a structure for drainage and water collection and reuse in landscape tree pools includes a ground 1 and a landscape tree pool wall 2 built on the ground 1, the landscape tree pool wall 2 is filled with planting soil 3, and greening trees 4 are planted in the planting soil 3, a special drainage pipe 5 is buried at the bottom of the inner side of the landscape tree pool wall 2, a soil surface drainage pipe 6 is buried on the side wall of the inner side of the landscape tree pool wall 2, a sewage drainage pipe 7 is buried in the ground 1, and the water inlet end of the sewage drainage pipe 7 passes through the inner side of the special drainage pipe 5, a sludge collection well 8 is buried in the ground 1, and the water outlet end of the sewage drainage pipe 7 is fixedly connected to the sludge collection well 8 and passes through the inner side of the sludge collection well 8.

[0020] In order to effectively isolate the direct contact between the soil and the drainage pipe, prevent soil particles from clogging the drainage pipe, and maintain the integrity and stability of the soil, a non-woven fabric soil isolation layer 9 is laid on the inner side of the planting soil 3, and an expanded clay hydrophobic layer 10 is laid on the inner side of the non-woven fabric soil isolation layer 9. The special drainage pipe 5 is buried inside the expanded clay hydrophobic layer 10.

[0021] In order to allow water to be directly discharged into the expanded clay hydrophobic layer 10 after entering the soil surface drainage pipe 6, the water outlet end of the soil surface drainage pipe 6 is buried in the non-woven fabric insulation layer 9 and the expanded clay hydrophobic layer 10, and a filter pipe cover is installed at the water inlet end of the soil surface drainage pipe 6.

[0022] In order to allow the water on the ground 1 to be discharged into the sludge collection well 8 , a drain outlet 11 is opened on the ground 1 , a manhole cover is installed in the drain outlet 11 , and the drain outlet 11 is connected to the sludge collection well 8 .

[0023] In order to collect the water in the sludge collection well 8 after filtering, a clean water collection well 12 is buried in the ground 1. The sludge collection well 8 and the clean water collection well 12 are an integrated structure. The sludge collection well 8 and the clean water collection well 12 are connected to each other on the side walls and near the top and a connecting opening is commonly provided. An impurity filter net 13 is fixedly connected to the connecting opening.

[0024] In order to discharge the filtered water for secondary use, a water pump 14 is installed at the bottom of the inner side of the clean water collection well 12. The water outlet end of the water pump 14 is fixedly connected to a water pipe 15. The upper end of the water pipe 15 is fixedly sleeved on the top of the clean water collection well 12 and penetrates to the outside of the top of the clean water collection well 12.

[0025] In order to drain excess water through the overflow pipe 16 when the clean water collecting well 12 is full, an overflow pipe 16 is installed on the side wall of the clean water collecting well 12 near the top, and the overflow pipe 16 is buried in the ground 1.

[0026] Working principle: On the ground 1, a landscape tree pool wall 2 is constructed according to the requirements of the greening design, and a special drainage pipe 5 is buried at the bottom of the inner side of the landscape tree pool wall 2. The special drainage pipe 5 can be cut in half with an ordinary PVC round pipe, and then many small holes for drainage are opened on the pipe wall. The material is easy to obtain and the operation is simple. After the special drainage pipe 5 is installed, a ceramsite hydrophobic layer 10 is covered on the special drainage pipe 5, and a non-woven fabric soil barrier layer 9 is laid on the top of the ceramsite hydrophobic layer 10, and a soil surface drainage pipe 6 is installed on the side wall of the inner side of the landscape tree pool wall 2, and then the landscape tree pool wall 2 can be filled with planting soil 3 and greening planting trees 4 can be planted. When watering the greening, the excess water in the planting soil 3 penetrates downward, and quickly and comprehensively penetrates into the special drainage pipe 5 through the non-woven fabric soil barrier layer 9 and the ceramsite hydrophobic layer 10, and then discharged to the sediment collection well 8 through the sewage drainage pipe 7 buried in the ground 1.

[0027] When the soil seepage drainage flow rate cannot catch up with the rainfall during heavy rain, the water on the planting soil 3 in the landscape tree pool wall 2 will also be quickly discharged into the ceramsite hydrophobic layer 10 through the soil surface drainage pipe 6, and quickly drained away through the special drainage pipe 5, so that the soil can be prevented from being soaked in water for a long time when the rain is heavy, so that the plant roots can also breathe well, and there will be no root rot, which is beneficial to plant growth. The water on the ground 1 is discharged into the sediment collection well 8 through the drainage port 11. The sediment collection well 8 collects the excess water generated by rainwater and watering greening, and collects it for secondary use. After the water collected by the sediment collection well 8 is filtered by the impurity filter 13, it enters the clean water collection well 12 through the connecting interface, and the water pump 14 outputs the clean water through the water pipe 15 for secondary use. When the water in the clean water collection well 12 is full, the excess water will be drained through the overflow pipe 16 to prevent the excessive collection of water from affecting drainage.

[0028] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
