FIELD: pipelines.
SUBSTANCE: invention is used in construction of pipelines of domestic sewage, rainwater, industrial and other gutters, pipelines for transportation of chemical liquids, relates to a device for application of mortar. Nozzle for automatic feed of bentonite in trenchless laying of glass composite pipes consists of polymer housing with stiffness ribs arranged along its perimeter. In the housing there is a check valve made with projections and slots and with possibility of axial movement. Check valve is also made of polymer. Besides, the nozzle consists of a nut installed on one threaded end of the housing with the possibility of being installed in a hole in the pipe wall made with splines, and a plug installed in the hole on the other end of the housing, which is made with the spline with possibility of its screwing in.
EFFECT: enabling efficient delivery of bentonite solution to the surface of the pushed glass composite pipe, thereby ensuring its effective pushing.
