Grouting plugging test device for simulating water leakage of tunnel crack

Abstract

The invention discloses a grouting plugging test device for simulating tunnel crack water leakage, and relates to the technical field of simulation tests. The grouting plugging test device for simulating water leakage of the tunnel crack comprises a fixed top plate and a fixed bottom plate, the fixed top plate is connected with a guide rod, the guide rod is also connected with the fixed bottom plate, a transparent barrel is arranged between the fixed top plate and the fixed bottom plate, and the fixed bottom plate is provided with a simulation gap for simulating the tunnel crack. The guide rod is provided with an adjusting pressing plate for pressing the top end of the transparent barrel, the fixed top plate is provided with a telescopic adjusting mechanism, the telescopic adjusting mechanism is connected with a test pressing plate for compacting the test bottom layer in the transparent barrel, the adjusting pressing plate is provided with a water inlet hole, the test pressing plate is provided with a water seepage hole, and the side wall of the transparent barrel is provided with a grouting hole. The grouting plugging test device for simulating water leakage of the tunnel crack can accurately simulate the condition of water leakage of the tunnel crack, and has the advantage of good test effect.
