s1: firstly, a concrete pipeline (1) is vertically placed, one of the expansion baffles (3) is opened to fill water between a front propping circular plate (2) and a rear propping circular plate (6) through an external water injection device, then the opened expansion baffle (3) is closed, the front propping circular plate (2) is in a closed watertight state, and then the front propping circular plate (2) is fixed in the concrete pipeline (1) through an external buckling device, so that subsequent pressing operation is facilitated;
s2: then when the whole compression resistance in the concrete pipeline (1) is tested, the positioning rod (15) is stirred to approach to one side of the rotating rod (13), one end of the positioning rod (15) is convenient to move to the fixed cylinder (16) and props against the fixed cylinder (16), then the rotating disc (14) is pushed at the moment, the rear propping circular plate (6) on the fixed cylinder (16) can be driven to move together and approach to the front propping circular plate (2), meanwhile, a water body can be extruded, if the quality of the concrete pipeline (1) is unqualified, namely, if the water pressure resistance is high, the concrete pipeline (1) can be propped up, and meanwhile, the slow pushing of the rear propping circular plate (6) can slowly press the concrete pipeline (1);
s3: after the whole resistance to compression in concrete pipe (1), just test concrete pipe (1) local water pressure impact, rotate rolling disc (14) this moment, because the position of locating lever (15) and side groove (9) position one-to-one, can confirm the position that telescopic baffle (3) was opened through rolling disc (14) pivoted position like this, then support round plate (6) removal and be close to preceding support round plate (2) after promoting again, let the water that exists before support round plate (2) and support round plate (6) after can strike concrete pipe (1) inner wall fast, if concrete pipe (1) quality is up to standard, can be broken by the rivers impact, and then can accomplish concrete pipe (1) internal local resistance to compression test equally.
