The present invention relates to a water feeding device for road side trees, which can supply and store water, plant supplements, drugs for pests, growth regulators, etc., for trees including landscape trees, road side trees, fruit trees, etc. Pre-existing water bags for trees had to be installed on trees for supplying water, causing bark damage in the installation site and stress in the growth of tree, and had to be mounted on trees, and thus could only supply a small quantity of water. However, the water feeding device of the present invention is installed at a lower part of a tree above the ground, and thus can store and supply larger quantities of water, nutrients, and the like； and can act as a fence for protecting a tree by being installed at an external angle with respect to the diameter of root of the tree. Additionally, the water feeding device has excellent durability due to being made of plastic, and thus can be used semi-permanently； prevents in advance potential contamination by foreign materials and accidents involving children or babies by having a cover installed on an upper part thereof； and serves as a temporary chair by having a chair sheet installed on an upper end thereof. Further, one or more spraying cocks and a water container water line capable of sharing water inside a water container are installed at a lower part of the device, so supplying water to one container causes all the other water feeding containers connected thereto by the water container water line to be filled with water as well.COPYRIGHT KIPO 2017본 발명은 수목용 가로수 급수통에 관한 것으로, 조경수, 가로수, 과수, 유실수, 등의 가로수 및 식목을 대상으로 수분과 영양제, 병해충 약제, 생장조절제 등을 공급 및 보관할 수 있는 것인 바, 기존의 수목전용 물주머니는 수목에 설치하여 물을 공급함으로써 설치부위의 수피훼손과 수목생장 스트레스가 발생할 수 있으며, 종래의 물주머니는 수목에 거치함으로써 물의 공급량이 소량으로 한정되나, 본 고안은 수목 하단 지상부에 설치됨으로 보다 많은 양의 수분, 양분 등을 보관, 공급할 수 있으며, 수목 근원직경을 중심으로 외각에 설치됨으로써 수목을 보호할 수 있는 경계울타리 기능도 겸할 수 있도록 한 것으로, 본 고안의 급수탱크는 플라스틱으로 이루어져 있어 내구성이 뛰어나 반영구적이고, 상부에는 뚜껑을 설치하여 이물질의 오염 및 어린이 및 유아 등의 피해를 미연에 방지하며, 상단에
