This creation is a kind of water pipe structure for livestock and poultry.The utility model mainly comprises a plurality of square water pipes connected in sequence and used for conveying a drinking water；Each square water pipe has a main pipe section and a square expansion section connected by a connecting section from one end of the main pipe section.The other end of the pipe section forms a pipe body structure consistent with the inner diameter of the expansion section.It is inserted and fixed in the square expansion section, and the two water pipes are connected to extend.Through the pipe body structure at the other end of the pipe section as the bonding surface,Glued to the inside diameter of the expansion section,Make the inner diameter of the water delivery holes of the two water pipes form the same straight line.Prevent the accumulation of impurities.Keep the water supply clean.本創作係為一種畜禽供水之水管構造，主要包含多數依序連接且用以輸送一飲用水的方形水管；每一方形水管具有一本管段以及一自該本管段之一端以連接段銜接之方形擴管段，該本管段之另一端部形成與擴管段內徑相符之管體結構，插接並固定在方形擴管段內而組接兩水管延長，透過本管段之另端管體結構作為粘貼面，粘合於擴管段內徑，使兩水管之輸水孔內徑形成同一直線，防止雜質堆積，保持供水清淨。
