The invention provides a water-tolerant test method of an adhesive under a static water pressure. The water-tolerant test method of the adhesive under the static water pressure comprises the steps of: taking a section of a polyethylene pipe; placing and fixing the pipe vertically, wherein the minimum distance from the pipe to a fixing material is about 100 mm, and the minimum distance from the pipe to the ground surface is 500 mm; mounting a bracket used for the placement of a pipe groove below a pipe orifice; arranging water pipe near the pipe and opening a water tap to fill the polyethylene pipe with water; using another section of the polyethylene pipe and a polyethylene plate to produce the pipe groove, and sticking and solidifying the pipe groove by using an adhesive for standby application; fixing the well-solidified pipe groove by using the bracket, cleaning a joint between the pipe groove and a hydraulic pressure pipe, and connecting the pipe orifice by using a hot melting belt; filling water into the pipe; placing the pipe statically so as to observe if the joint is leaked, and if not, confirming that the pipe is qualified. The water-tolerant test method of the adhesive under the static water pressure has the beneficial effect that the water-tolerant performance of the adhesive can be tested rapidly and efficiently.
