MPP pipe for preventing post-construction settlement

The MPP pipe for preventing post-construction settlement comprises a pipe body, the pipe body is fixedly connected with a first mounting block and a second mounting block in a penetrating mode, and an anti-settlement mechanism is arranged in the first mounting block; the anti-sedimentation mechanism comprises two mounting grooves and two functional cavities, the mounting grooves and the functional cavities are formed in a first mounting block, lower sliding blocks are slidably connected in the mounting grooves, two liquid cavities are formed in the first mounting block, and driving plates are slidably connected in the liquid cavities in a sealed mode; the first mounting block is slidably connected with two driving rods in a penetrating mode, and one end of each driving rod penetrates and extends into the corresponding mounting groove and is fixedly connected with the side wall of the lower sliding block. The pipe fitting has the advantages that the pipe fitting can automatically prevent sedimentation through
