A lateral union base (31, 17) for receiving water from a lateral irrigation pipe (2), which is employed for the connection and supply of distributors (3, 4). It consists of a curved surface (20) of very limited dimensions with an elevated protrusion (d4) preferably in the form of a tip (32) with a closed or open bottom. The bases (31, 17) are incorporated in the interior of the lateral irrigation pipe (2) at predefined distances by the method of simple extrusion during manufacturing of the pipe (2) and are covered by the pipe (2) which is swollen and protrudes locally at the welding areas. For the connection of the distributors (3, 4) which have a coupling nipple portion of respective form, a hole is opened on the pipe (2) at the area of the local swelling (d4). The distributor (3, 4) with its respective end (14,15) is inserted by applying radial pressure and is fixed in the interior of the socket (19) of the base (31, 17). |
