A device for testing the durability of a shield tunnel joint waterproofing under the seabed, characterized by, include: The test chamber (1) has an opening on one side for easy observation, and a simulated tunnel (3) is fixedly installed at the bottom of the test chamber (1). A simulated trolley (4) is set on top of a simulated tunnel (3). The simulated trolley (4) is equipped with a motor for driving the simulated trolley (4) to move. The simulated trolley (4) moves laterally along the top of the simulated tunnel (3). Multiple load boxes (2) are fixed to the inner walls of both sides of the test chamber (1) by a snap-fit assembly. The multiple load boxes (2) on both sides are staggered. The top of the multiple load boxes (2) and the simulation trolley (4) are provided with connecting assemblies for connecting the load boxes (2) and the simulation trolley (4).
2. The apparatus for testing the durability of a shield tunnel joint waterproofing according to claim 1, wherein The locking assembly includes a positioning rod (13) that slides through the test chamber (1). One end of the positioning rod (13) is fixedly connected to a limiting plate (15), and the other end of the positioning rod (13) is fixedly connected to a connecting plate (12). Two locking blocks (11) are fixedly connected to one side of the connecting plate (12). Two symmetrically arranged first locking slots (10) are opened on one side of the load box (2), and the first locking slots (10) engage with the locking blocks (11).
3. The apparatus for testing the durability of a shield tunnel joint waterproofing according to claim 2, wherein, A tension spring (14) is fixedly connected to the side of the limiting plate (15) near the test chamber (1), and the tension spring (14) is sleeved on the positioning rod (13).
4. The apparatus for testing the durability of a shield tunnel joint waterproofing according to claim 2, wherein A protrusion (8) is also fixedly connected to one side of the connecting plate (12).
