Patent No. 10-0553005 (Rooftop greening system and its construction method, hereinafter referred to as the conventional technology) for greening rooftops has been proposed.

The conventional technology is to protect the thermal energy of a building and implement a greening space on the roof of a building for the purpose of rooftop greening. It can be seen that it is composed so that various types of trees can be vegetated according to the depth of the tree. Since the conventional technology configured as described above is configured on the premise of rooftop greening, there is an inconvenience in water supply in the method of greening the rooftop using rainwater as in the present invention, and there is an inconvenient difference in management of automatic water supply. .

An object of the present invention is to provide a device and method capable of providing water to vegetation on a rooftop by storing even a small amount of rainwater in order to green the rooftop.

In the device and method of rooftop greening using rainwater according to this description, it is configured on the premise that waterproofing works 100% through waterproofing work whether it is an existing building or a new building.

The process of arranging several storage bins on the roof in a group by closely connecting them, the process of connecting each storage tank with a connector so that the entire storage tank can be filled with the same amount of water, the process of combining a pedestal on top of the storage tank, The process of arranging a wick from the pedestal to the bottom of the storage, the process of connecting one or more reservoirs and the water tank with a supply pipe, the process of installing a water level sensor in one or more of the storage, and the process of applying a nonwoven fabric to the pedestal on the storage. The process of laying, the process of designing a hill and a trail on the storage, the process of installing a fence on the boundary between the hill and the trail, the process of filling the inside of the fence with culture soil, and the grass mat on the strip of grass and the strip of grass on the promenade The process of excretion, the process of planting grass or plants on the culture soil, the process of supplying water from the water tank to the storage by operating the pump, the process of filling the entire storage with water through a connection pipe to one storage, The process of stopping or operating the pump by the water level sensor; It was constructed so that it could be transferred to a tank, and rainwater from the rooftop was automatically provided to the plants to green the rooftop.

In the rooftop greening method of the present invention, several water reservoirs are combined in front and rear and left and right on the roof of a building to form an integrated group.

The storage was constructed in a rectangular shape so that it could be closely connected in front and rear and left and right.

A groove is formed at the upper end of each side of the storage so that overflowing water in the storage can be easily overflowed, and a connecting rod is inserted in each side of the storage so that water can be supplied to other storage through the connecting rod.

A pedestal was coupled to the top of the storage and a pillar was formed at the bottom of the pedestal to support the weight acting on the pedestal.

The one or more reservoirs are connected to the rainwater tank so that the water in the water tank can be quickly transferred to the reservoir.

A nonwoven fabric was placed on the pedestal above the storage to prevent inflow of culture soil into the storage.

Several holes were drilled in the pedestal so that rainwater drained into the culture soil could be easily accommodated in the storage.

A plurality of wicks are fixed to the hole of the pedestal, and the end of the wick advances to the bottom of the storage to transport water in the storage to the nonwoven fabric through the wick.

As described above, when the storage is arranged on the roof and the wick and nonwoven fabric are installed, the hill to plant the plants is designed and the height of the culture soil is adjusted according to the height of the hill so that large plants and small plants can be easily planted.

A trail was designed between the hills, and a fence was installed at the boundary between the hill and the trail, but the height of the fence was adjusted according to the height of the hill, and the cultivation soil of the hill was prevented from leaking into the trail.

Since the fence is built on the non-woven fabric of the storage, the lower part of the fence is configured in a bent shape so that the fence does not fall, and the bent part is located under the culture soil and supported on the grass of the walkway so that the fence is not pushed to the walkway by the culture soil. composed.

The height of the fence was adjusted according to the height of the culture soil to prevent the culture soil from overflowing the trail.

The use of a fence can be omitted by adjusting the slope between the trail and the hill.

On the non-woven fabric above the storage designed as a walkway, strips of grass are closely laid and a grass mat is placed on top of it to prevent damage to the leaves of the grass even when taking a walk.

The non-woven fabric is not pushed by several protrusions formed on the upper surface of the support of the storage, and the protrusions penetrate the strip grass placed on the trail so that the grass is not pushed when a person walks.

On the roof constructed as described above, rain is drained from the garden and the trail to fill the storage tank, and the rainwater overflowing the storage storage is accommodated in the water tank.

It was configured to supply water from the water tank to more than one reservoir under the same conditions. Water is supplied to one or more reservoirs, and when the water in the reservoir fills up to the connecting pipe, it is transferred to the other reservoir through the connecting pipe so that all the reservoirs can store water at the same height, and the water in all reservoirs decreases is not the same. A water level sensor is installed in one or more reservoirs, and when the water level in the reservoir decreases, a pump in the water tank is operated to transfer water to the reservoir and fill the reservoir.

Installing the water tank at a location that can naturally receive rainwater on the roof can save power consumption for pumping the water in the water tank, and it may be preferable to install the water tank in a toilet on the lower floor.

In addition, the auxiliary water tank is installed on the roof to supply water from the auxiliary tank to the water tank without power, and the valve is operated according to the sensor of the water tank using a motorized valve.

The size of the water tank can be adjusted according to the width of the roof, and an auxiliary tank is installed so that water in the auxiliary tank can be used in case of severe drought, and water can be supplied from the outside.

As described above, the rainwater on the roof can be stored in the water tank, the water in the storage can be supplied from the water tank by the sensor of the storage, and the insufficient water in the water tank is operated by the sensor in the water tank to operate the valve of the auxiliary tank. It is configured to be supplied with water, and the water overflowing in the water tank is configured to be transferred to the auxiliary tank.

The water overflowing the auxiliary tank is configured to be discharged to the rainwater main tank (not shown).

The rooftop greening device and method according to the present invention use rainwater but can store and use it, and since plants can grow in any part under the same conditions, there is no need for special partial management, and there is no need for special management of rainwater. Since there is no need for management, labor costs are saved, and since the rooftop is filled with water, energy for heating and cooling can be saved. A promenade and garden are installed separately so that you can take a walk in the green area, recovering from physical and mental fatigue and emotional stability through the experience of the green area. can provide.
