Detailed ways

The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments. The present invention is not limited to the exemplary embodiments disclosed below, but can be implemented in various forms.

When it rains, part of the rainwater directly irrigates the middle planting area 2, and gradually infiltrates along the ceramsite layer 23, the planting soil layer 24, and the recycled aggregate layer 25, and is absorbed by the trees in the process, and the excess rainwater is stored in the regeneration area. In the collection layer 25. Another part of rainwater falls on the wooden grid seat 31, falls to the surface of the lower water layer 4 through the gap of the wooden grid, flows along the slope to the edge permeable through hole 41 and enters the lower hollow outer layer water collection area 3 to collect. A part of the rainwater in the outer catchment area 3 is discharged into the recycled aggregate layer 25 through the one-way valve II 22. When the recycled aggregate layer 25 is full of water, the excess water will flow out through the one-way valve. I21 discharges into the outer catchment area 4. The outer layer catchment area 4 continues to store water to a certain height and discharges to the underground pipe network from the water pipe 12. This part of water is unpolluted water and can be directly discharged into rivers.

In fair weather, trees can absorb water from the recycled aggregate layer through their roots. The one-way valve I21 and the one-way valve II22 on the concrete wall of the inner planting area cooperate with each other to ensure that the excess water overflows into the catchment area in one direction. In this way, trees can be avoided from waterlogging or lack of water, and water-saving self-irrigation can be realized.

Construction method.

1) Manufacturing process.

The production procedure of the prefabricated pool body of the ecological tree pool is: preparation of recycled concrete --- formwork --- pouring --- demoulding, placing and condensation --- taking the backing plate and sprinkling water for maintenance.

If the surface of the pool body is rough, it can be plastered with cement slurry.

As a specific embodiment, the outer diameter of the tree pool can be set to 2.8m, and the wall thickness of the box body is 20cm. The total height of the tree pond is 1.1m, of which the ceramsite layer is 50mm, the planting soil layer is 85cm, and the recycled aggregate layer is 20cm.

2) Earth excavation.

After the measurement and setting out, carefully dig the soil pit with a pick to avoid disturbing the foundation soil, and it is necessary to clean up the soil pit, clean up tree roots, turf, garbage, gravel, etc., to ensure that the soil layer and inner wall are smooth.

3) Site transportation of tree pool components.

Due to the large volume and weight of the tree pool, mechanical loading and unloading is used for transportation. Special attention should be paid during transportation, and attention should be paid to loading and unloading methods to avoid loss.

4) Installation of tree pond prefabricated components.

Install tree pool components according to the design elevation, ensure that the seat is just 0.5m above the ground, and consider factors such as buildings, garden roads, and pipelines beside the site, determine the vertical connection mode of the edge area, and confirm the position of the box drain, so that The underground pipe network is connected, and the contradictions in drainage and channels are minimized.

5) Sprinkle the filling.

According to the design height of each layer, pave the recycled aggregate-construction dregs-ceramsite successively to ensure that each layer is uniform and dense. Recycled aggregates should meet the maximum particle size of not more than 37.5mm, and the nominal maximum size is 33.7mm, and must be processed by impact crushing. Construction sites in urban or suburban areas must have measures to prevent dust and noise pollution to achieve green and clean production. It is recommended to choose three specifications of 20-30mm, 10-20mm, and 5-10mm for recycled aggregates for the grassroots. The second layer of flushing materials is slag. Pay attention to dust control when paving construction slag, and build dust-proof barriers in the construction area. When filling the slag, it is necessary to add the slag modifier in advance. The surface filler is ceramsite, and most of its appearance features are round or oval spheres. Fly ash ceramsite with a density grade greater than 400 should be used, the maximum particle size should not be greater than 33mm, the pavement height should be 50mm, and there should be no mixed inclusions or clay blocks.

6) Earthwork backfill and slope protection treatment.

After the filling of the tree pond is completed, the soil samples on both sides are manually transported and compacted with an iron rammer. After the backfilling work is completed, 4-6cm of sand and gravel is backfilled according to the designed section, and finally the finished product is accepted.

7) Finished product testing.

Check the integrity and elevation of the tree pool, and ensure that the tree pool is firmly built, the top surface is flat, beautiful, dense, and free from debris pollution.

8) Site clearing.

Remove remaining materials in time, and clean up polluted sites and roads.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
