[Landscape Construction] Tree planting avoid water / poor drainage areas.

It is a more difficult construction.

It's not that hard to think about, but it's a difficult decision to make and run.

I will show you a case where there is a lot of walking.

Tree planting work is given to the square in front of the main business section.

Plant zelkova in thermal form.

Zelkova is a species with difficulty in planting. R20 size should be planted.

Because it is a construction in the summer, the concern about planting trees is our top priority, and risk management was needed.

Korea's summer climate, Zelkova is not a suitable species for planting.

The square is already made up of existing stone pavement, so you need to set the interval and create blood.

Set the section and cut existing stone pavings.

 

Finish the composition by machine work after packing cut.

The planting hole size is 2mX2mXH2.0.

 

First of all, we make sure that the water is drained and the drainage is good.

 

Not all, but over time, there is a poor drainage section with poor drainage as in the above section.

My troubles started from here.

How do I do it. In the middle of such a place, if give up, there is a problem with the thermal concept food. 

So I thought about solving the problem with induction drainage.

After removing water, create a gravel layer to the height where the drainage was stagnated during fresh water.

Drainage stagnation should be maintained until a minimum safety layer is secured in the event of the same phenomenon.

 

After that, form a sand layer and prepare for drainage once more.

 

Then plant trees. Use underground landings instead of landings to minimize obstacles to street users' walking.

 

Except for the exposed section of the roots, install trusses to install the wooden deck and finish the deck.

To create comfort in walking on the square.

For a more clean finish, the intermediate finish between deck and stone is finished with an edge.

 

This is the last addition to induction drainage.

We pierce the core to form a ventilation hole around the hemorrhage of the poor drainage section.

The depth is 2m, it is the same depth as the depth of planting hole, and it is considered as two design places around the four sides.

The vent cover is finished with a built-in stainless steel finish.

 

It was planting construction of poor area of ​​drainage in the urban plaza.

Because there are various limitations such as equipment use when replacing defects, we had to plant in consideration of defects.

It seems to be growing well without defect now because it was difficult construction.
